Personal laws in India govern the most intimate legal events of a person’s life, and they do so by a method no other branch of Indian law uses. A contract is a contract whoever signs it, and a theft is a theft whoever commits it, because the general law of India is territorial: it applies to everyone within the territory on the same terms. Marriage, divorce, maintenance, adoption, guardianship and succession work differently. For those subjects, the first question a court asks is not what happened but who the parties are, because the applicable law is assigned by religious community. A Hindu couple divorces under one statute, a Muslim couple under a mixture of statute and uncodified religious law, a Christian couple under a statute first enacted in the nineteenth century, and a couple who marry before a marriage officer under a secular code that either of them could have chosen. The same legal system therefore contains several family laws running in parallel, and the map of which law governs whom is the subject of this guide.

Two features of that map surprise most readers who meet it for the first time. The first is that personal law in India is neither wholly religious nor wholly statutory. Some of it is codified in Acts of Parliament that a court applies as it applies any other statute. Some of it is found in classical texts, commentaries and precedent, administered by courts but never enacted by any legislature. Some of it is custom, which the law recognises as binding where a community has followed it long enough and consistently enough. The second surprise is constitutional. The subjects that make up personal law sit on the Concurrent List of the Seventh Schedule, which means Parliament and the state legislatures share competence over them, and the long national argument about reforming personal law has been conducted for decades as though only Parliament could act. Both surprises are structural, and both explain more about the field than any single statute in it.

Personal laws in India: the shape of the field

Personal law is best understood as a defined territory inside private law. Inside the territory, the rule of decision depends on the community to which the parties belong. Outside it, the ordinary territorial law governs everyone alike. The territory’s boundaries were drawn by history rather than by logic, and they cover the events that mark a family’s legal existence: whether a marriage is valid and how it may be dissolved, what a spouse may claim when a marriage ends or a partner dies, who inherits property and in what shares, who may adopt a child and with what consequences, who is the guardian of a minor and who manages the minor’s property, and how a joint family’s property is held and divided. The Constitution’s own drafting preserves the boundary almost exactly as it found it, because Entry 5 of the Concurrent List, examined in detail below, closes with a sweeping clause covering all matters in respect of which parties in judicial proceedings were, immediately before the Constitution commenced, subject to their personal law.

Why does a person’s religion decide which family law governs them?

Because the colonial state chose to administer family matters through the religious law of the parties rather than through a single territorial code, and the republic kept that architecture. The choice hardened into precedent over a hundred and fifty years and was carried into the Constitution, whose lists assume personal law exists and distribute power over it without abolishing it.

The depth of that inheritance is easy to underestimate. When the Constitution commenced in 1950, it did not create the personal law system; it received one that was already more than a century and a half old, with its own case law, its own translated texts and its own professional habits. What the Constitution changed was the distribution of power over the system and the rights framework surrounding it. Parliament and the state legislatures acquired concurrent power to legislate on every subject in the field. The freedom of religion provisions guaranteed communities a protected space for religious practice while expressly preserving the state’s power to legislate for social welfare and reform. The directive principles recorded an aspiration toward a uniform civil code without making it enforceable. Everything that has happened in the field since 1950, every codification, every amendment, every constitutional challenge, is a working out of tensions that the constitutional text itself built in.

A reader who grasps the shape of the field can predict the shape of almost every controversy within it. A dispute about a rule of Muslim divorce is never only a dispute about divorce; it is also a dispute about whether the rule is codified or uncodified, because that determines whether it can be tested against fundamental rights at all. A dispute about a Hindu succession amendment is never only about shares; it is also a dispute about which legislature may act, because the subject is concurrent and several states amended the law for their own territories before Parliament acted for the whole country. A dispute about a uniform civil code is never only about uniformity; it is also a dispute about consent, because the communities whose law would be replaced did not all arrive at the existing settlement by the same route. The sections that follow take the field apart in the order that makes those connections visible: first the colonial settlement that created it, then the constitutional architecture that houses it, then the doctrine that decides what may be challenged, then the statutes community by community, then the secular overlays and exceptions, and finally the two standing positions between which every reform argument moves.

One institution recurs through the field’s modern history so regularly that it deserves naming in the map: the Law Commission of India. The Commission is not a legislature and binds no one, but the rhythm of personal law reform in the republic has repeatedly run through it: a reference or a suo motu study, a consultation paper that maps the disagreement, a report that recommends a drafted solution, and then, after an interval that varies from years to decades, legislation that follows the report in whole or in part. The equalisation of Christian divorce in 2001 followed that rhythm, as did the official thinking on marriage registration and on the reform of family law as a whole, where the Commission’s consultation paper of 2018 and its successor body’s reopening of the uniform code question in 2023 mark the two poles of the institutional debate. A reader tracing any live controversy in the field will usually find, behind the parliamentary positions, a Commission document in which the arguments were first set out in their durable form, and the habit of looking for it is worth acquiring early. The Commission’s role also explains a feature of the field that puzzles newcomers: how much of its law reform is drafted before it is decided. The bills exist, in draft, for years before the politics exists to pass them, which is why the field’s history reads so often as a story of old drafts awaiting their moment.

A word about names will prevent a confusion that runs through popular writing on the subject. Lawyers in India use personal law and family law for overlapping but distinguishable things. Family law names the subject matter: marriage, divorce, maintenance, children, succession. Personal law names the assignment mechanism: the body of rules that governs a person on those subjects because of the community to which that person belongs. The two terms cross because most family law in India is personal law, but they are not interchangeable. The Indian Succession Act is a personal law for Christians and a secular statute in its drafting character at the same time. The Special Marriage Act is family law that is deliberately not personal law, since it governs by election rather than by birth. And much of what fills the family courts, the procedure code’s maintenance remedy, the child marriage prohibition, the violence protection statute, is family law of general application that no one calls personal law at all. The distinction matters because arguments that are true of one category are routinely transferred to the other: a claim that personal law is religious in origin, true of much of it, tells nothing about whether family law should be codified, and a claim that family law is a fit subject for uniform legislation, which hardly anyone denies in the abstract, settles nothing about which community’s rules the uniform law should carry. This guide uses personal law in the assignment sense throughout.

The map also decides cases at the country’s edges, where the personal law system meets foreign law. A marriage celebrated abroad between two persons domiciled in India raises the question whether its validity is tested by the law of the place of celebration or by the personal law of the parties, and Indian courts have generally tested capacity to marry by the parties’ personal law while accepting the form of the place of celebration. A decree of divorce granted by a foreign court to a couple married under an Indian personal law raises the harder question whether the decree will be recognised, and the courts, applying the principles the Law Commission examined in its sixty-fifth report on the recognition of foreign divorces, have refused recognition where the foreign court took jurisdiction on a ground unknown to the law under which the parties married, or granted relief on a ground that law does not recognise. The Foreign Marriage Act of 1969, Act 33 of 1969, supplies a statutory channel for marriages of Indian citizens abroad before Indian diplomatic and consular officers. These border questions are not a footnote to the system; they are one of its working proofs, because they show that personal law in India functions as a genuine system of private international law inside a single state, assigning each person a law that travels with them in a way territorial law does not.

The colonial settlement: how religion became a rule of decision

The founding document of the personal law system is a regulation of 1772. Warren Hastings’s judicial plan for Bengal, embodied in Regulation II of that year, directed that in all suits regarding inheritance, marriage, caste and other religious usages or institutions, the laws of the Koran with respect to Muhammadans and those of the Shaster with respect to Hindus should be invariably adhered to. The formula was repeated, with variations, as British administration spread, and the later instruments that carried it, including provisions of the Punjab Laws Act of 1872, the Madras Civil Courts Act of 1873 and the Oudh Laws Act of 1876, show how durable the settlement proved. Its logic was administrative. The East India Company took revenue, crime, commerce and policing into its own legal order, and left the family and religious life of its subjects to laws it regarded as theirs. The result was a durable division of the legal field into a religiously determined core and a territorially applicable remainder, a division the Constitution inherited rather than designed.

Administering the religious law of two civilisations was a task the Company’s courts were not equipped for, and the way they equipped themselves shaped the law they produced. Courts at first sat with Hindu pandits and Muslim law officers who stated the applicable rule from the texts. The office of court pandit and court maulavi was abolished in 1864, by which time the courts had accumulated translations, digests and a body of precedent of their own. William Jones’s translation of the Institutes of Manu and Charles Hamilton’s translation of the Hedaya, a Hanafi legal compendium, gave English-speaking judges direct access to texts they treated as authoritative codes. The body of law that emerged from this process is conventionally called Anglo-Hindu law and Anglo-Muhammadan law, and the names are honest: it was Hindu and Muslim law as selected, translated and systematised by British courts, increasingly governed by precedent in the English manner, so that a rule once decided tended to displace the textual diversity from which it had been drawn.

The translation enterprise that underpinned the system deserves a closer look, because it selected the law it claimed merely to find. In 1776 Nathaniel Brassey Halhed published A Code of Gentoo Laws, compiled by a committee of pandits and rendered into English through a Persian intermediary, the first attempt to give the Company’s judges a Hindu code between covers. Sir William Jones, himself a judge of the Calcutta Supreme Court, translated the Institutes of Manu at the end of the century, and Jagannatha Tercapanchanana’s great digest, translated by Henry Thomas Colebrooke and published in 1798 as A Digest of Hindu Law, supplied the courts with an ordered statement of the law of contracts and succession drawn from the commentarial tradition. For Muslim law, Hamilton’s Hedaya gave the courts a single Hanafi authority of great prestige. The consequence of building a legal system on a small shelf of translations was a double narrowing. Within Hindu law, the digest tradition of the commentaries was privileged over the diversity of regional practice, and the Mitakshara’s authority expanded in the courts beyond the place it had occupied in life. Within Muslim law, the Hanafi school of the Hedaya became the presumptive law for Sunni litigants generally. Above the Indian courts sat the Judicial Committee of the Privy Council in London, whose appeals in personal law cases, decided by judges trained in English law working from translations and counsel’s arguments, settled points of doctrine with an authority no Indian institution could match. When the republic abolished Privy Council jurisdiction and vested final appeal in its own Supreme Court, the body of doctrine the Committee had built remained, and much of it remains the governing statement of the uncodified law.

Who actually stated the law when a colonial court applied it?

In the early decades, religious scholars attached to the courts stated it: pandits for Hindu law and maulavis for Muslim law, answering questions put by judges who could not read the sources. After those offices were abolished in 1864, judges worked from translations and earlier decisions, which is why precedent sits at the centre of the inherited law.

The colonial settlement also produced the system’s escape hatches and safety valves, several of which remain in force. The Caste Disabilities Removal Act of 1850, Act 21 of 1850, provided that a person who renounced their religion or was excluded from caste would not for that reason forfeit property or inheritance rights, a statute aimed at converts to Christianity whom the older law would have stripped of their patrimony. The Converts’ Marriage Dissolution Act of 1866, Act 21 of 1866, allowed a spouse whose partner refused to follow a conversion to Christianity to seek dissolution. The Special Marriage Act of 1872, enacted as Act III of that year after Henry Sumner Maine’s efforts, created the first civil form of marriage, though at a price that limited its use for decades: the parties had to declare that they professed none of the listed religions, so the secular route originally required a formal renunciation of faith. The Act of 1954 that replaced it, examined below, removed that condition and turned the exception into a general alternative. Each of these statutes illustrates the working method of the system: the religious core was left in place, and pressure was relieved at its edges by targeted legislation rather than by replacing the core.

One further feature of the colonial period matters for everything that follows. The personal law administered by the courts was never the whole of a community’s lived law. Custom, where it was ancient, certain and continuously observed, could displace the textual rule, and the courts developed tests for recognising it, insisting that a custom be proved as a fact and that it not be unreasonable or opposed to public policy. Whole regions and communities lived substantially by custom: the matrilineal systems of the Malabar coast, the customary law of Punjab that colonial administrators recorded in manuals of customary law, and the usages of tribal communities across the country. The system’s official picture, a Hindu law, a Muslim law and a small set of statutes for the rest, was always a simplification of a more varied reality, and careful writers on every side of the modern debate concede that personal laws are not uniform within each community, because custom, region and sect produce substantial internal variation.

The sources from which personal law is drawn

A reader who asks where a rule of personal law is written down receives five different answers, and knowing which answer applies to a given rule is most of what expertise in this field consists in. The first source is legislation, and it needs no elaboration beyond the statutes mapped in this guide. The second is the classical text: the Dharmashastra literature for Hindu law, of which the Manusmriti is the best known and the commentaries are the most legally operative, and for Muslim law the Quran, the traditions of the Prophet, and the juristic elaboration built on them, of which the Hedaya for Hanafis and the Shara’ya-ul-Islam for Shias are the works Indian courts have most used. The third source is the commentary and the digest, the layer at which the classical texts were systematised: the Mitakshara of Vijnaneshvara and the Dayabhaga of Jimutavahana for Hindu law are not ancient scriptures but medieval juristic works whose authority the courts elevated into the organising schemes of two schools. The fourth source is precedent, which in the Anglo-Indian system does not merely evidence the law but makes it, so that a Privy Council ruling of the nineteenth century on a point of adoption or succession can govern a dispute between parties whose families never heard of the case. The fifth source is custom, which operates inside every system in the field, recognised under conditions each system states differently.

The interaction of the five sources explains behaviour that puzzles outsiders. A Hindu law question on a subject the code statutes cover is answered from the statute, and the older sources are consulted only to interpret it, because the code declares its own overriding effect. A Hindu law question outside the codes, or a Muslim law question on an uncodified subject, is answered from precedent first, from the commentaries and texts behind the precedent second, and from custom where custom is pleaded and proved. A court asked to depart from an old precedent in the uncodified field faces the discipline of stare decisis in its strictest form, because the precedent is frequently the only ascertainable statement of the rule, which is one reason uncodified personal law changes slowly even when judges doubt its justice. The professional literature mirrors the structure: the standard modern works, of which Mulla’s treatises on Hindu law and on Mohammedan law are the enduring examples, organise the uncodified law as a body of propositions supported by case citations, so that the law a practitioner advises on is, in form, a synthesis of decisions rather than a translation of scripture. The religious text is the system’s ultimate warrant; the case report is its working text. Holding both halves of that sentence is essential to describing the field honestly, because partisans of every position habitually quote only the half that serves them.

Two gap-filling devices complete the account of the sources. Where no text, precedent or custom supplied a rule, the colonial courts decided by justice, equity and good conscience, a formula that in practice imported English law principles judged suitable to Indian conditions, and through which doctrines of English equity entered the personal law’s interstices, in guardianship above all. Within Hindu law, the doctrine of factum valet, that an act which ought not to have been done is nonetheless valid when done, drawn from the commentaries, allowed courts to sustain transactions, adoptions among them, that violated directory texts, and its contests with the stricter reading of the same texts run through the classical case law. Both devices matter to the modern reader for the same reason: they show the uncodified law possessing its own internal techniques of change, slower than legislation and narrower than constitutional review, but real, and they explain why the boundary between the uncodified law’s content and its judges’ preferences has been contested in every generation.

The constitutional architecture: Entry 5 and the Concurrent List

The Constitution distributes legislative power through the three lists of the Seventh Schedule, and the entire personal law field sits in a single entry of the third list. Entry 5 of the Concurrent List reads: marriage and divorce; infants and minors; adoption; wills, intestacy and succession; joint family and partition; all matters in respect of which parties in judicial proceedings were immediately before the commencement of this Constitution subject to their personal law. Every element of the entry repays attention. The named heads cover the field’s working subjects one by one. The closing clause then sweeps in anything the named heads might have missed by tying the entry to the historical personal law jurisdiction, so the entry is simultaneously a list and a historical reference. The fuller treatment of how the three lists divide competence, and of what follows when entries overlap, belongs to the guide to the Seventh Schedule and its three lists, which owns that ground; what matters here is what the entry’s placement does to personal law.

Placement on the Concurrent List means that both Parliament and a state legislature may legislate on marriage, divorce, adoption and succession, with neither level of government excluded. This is the article’s central constitutional fact, and it is the one most often misstated in public discussion, where personal law is routinely described as a central subject and reform is debated as though the Union government were the only possible author. The correct position is the one the entry states. A state legislature that wishes to amend the operation of a personal law statute within its territory is exercising a competence the Constitution gives it, subject to one control: the repugnancy rule in Article 254. Where a state law on a concurrent subject conflicts with a parliamentary law, the parliamentary law prevails and the state law is void to the extent of the repugnancy, unless the state law was reserved for the President’s consideration and received the President’s assent, in which case it prevails within that state, though Parliament remains free to legislate over it later. Reform of personal law has therefore always had two possible doors, and the history of the field shows both being used.

States have used the power in ways that changed the law for millions of people. A Kerala statute of 1975 abolished the joint Hindu family system outright in that state, ending by legislation a form of property holding that the central succession statute continued to recognise elsewhere. Several states, beginning with Andhra Pradesh and followed by Tamil Nadu, Karnataka and Maharashtra, amended the Hindu Succession Act in its application to their territories to make unmarried daughters coparceners by birth in joint family property, years before Parliament made the same change for the whole country by the amendment of 2005 whose own history is told in its specialist article. The state of Uttarakhand has carried the logic furthest by enacting a uniform civil code for its residents, the Uniform Civil Code, Uttarakhand, 2024, Act 3 of 2024, passed by the state assembly in February 2024, assented to by the President in March 2024 and brought into force on 27 January 2025, which replaces the community-specific rules with a single code for the state’s residents while excluding Scheduled Tribes from its scope. That experiment, its drafting history and its contested reception are the property of the article that owns the uniform civil code debate, linked below; its significance here is narrower and purely constitutional. It is the standing proof that the Concurrent List placement is not a technicality. A state did what the national debate assumed only Parliament could do.

Nor was the placement new in 1950. The Government of India Act of 1935, whose three-list distribution of legislative power the Constitution adapted, had likewise placed marriage and divorce, infants and minors, adoption, wills, intestacy and succession in its concurrent list, and the Constituent Assembly’s choice was to continue a federal allocation that had operated through the provincial autonomy years, during which provincial legislatures had already legislated on the field, as the Bombay bigamy statute that produced the 1952 case itself demonstrates. The continuity matters for interpretation: arguments that the framers of 1950 invented the concurrent placement to enable a future uniform code, or conversely that they placed the subjects concurrently by oversight, both read too much into a deliberate inheritance.

Against the concurrent competence stands the Constitution’s statement of aspiration. Article 44, in the chapter on directive principles of state policy, provides that the state shall endeavour to secure for the citizens a uniform civil code throughout the territory of India. Three features of that provision determine its legal weight. It is a directive principle, and Article 37 declares the principles in that chapter fundamental in the governance of the country while expressly providing that they shall not be enforceable by any court. It is addressed to the state, a term that covers state governments as much as the Union, which fits the concurrent placement of the subject. And its verb is endeavour: it records a direction of travel rather than a completed obligation. In the Constituent Assembly, the provision, then numbered as draft Article 35, was debated on 23 November 1948. Members including Mohammad Ismail Sahib, Naziruddin Ahmad and Pocker Sahib Bahadur moved amendments to protect personal law from the reach of a future code, arguing that a community’s law of marriage and inheritance was part of its religion and culture. K. M. Munshi and Alladi Krishnaswami Ayyar defended the clause as a measure of national unity and eventual equality. B. R. Ambedkar, steering the draft, answered that the provision conferred a power rather than imposing a duty, and that a future Parliament could, if it chose, begin by applying a code only to those who declared themselves willing to be bound by it. The amendments were rejected and the aspiration entered the Constitution in its unenforceable form, which is where it has remained.

The courts have policed the boundary between the aspiration and the enforceable rights on either side of it. In Minerva Mills v. Union of India in 1980, the Supreme Court held that the Constitution rests on a harmony between fundamental rights and directive principles, and that to give absolute primacy to one over the other would disturb that harmony; Article 44 could therefore not be read as a licence to override Part III, nor Part III as a reason to treat the directive as meaningless. In Sarla Mudgal v. Union of India in 1995, a bench of the Court held that a Hindu husband who converted to Islam and married again without dissolving his first marriage committed the offence of bigamy, because conversion does not dissolve a marriage solemnised under the Hindu Marriage Act, and the judgment went on to urge the government to look afresh at Article 44. Five years later, in Lily Thomas v. Union of India in 2000, the Court clarified that the Sarla Mudgal judgment had issued no direction to enact a uniform civil code and that the observations on Article 44 were not a mandate; the question of when and whether to legislate remained with the legislatures. The constitutional position is therefore a three-part settlement: the aspiration is recorded, the competence to act on it is concurrent, and the decision to act is legislative rather than judicial. Any account that collapses those three parts into a claim that the Constitution commands a code, or forbids one, misstates all of them.

The mechanics of concurrence deserve one further step, because they explain how the state amendments already mentioned were legally possible against the text of a central Act. A state amendment to a parliamentary statute on a concurrent subject is itself a law on that subject, and where it conflicts with the central text it survives only through the assent route in the second limb of Article 254: the state bill is reserved by the Governor for the President’s consideration, the President assents, and the amended law then prevails in that state notwithstanding the repugnancy. The state succession amendments that made daughters coparceners travelled exactly this road, which is why the map of Hindu succession between the middle of the 1980s and 2005 was a patchwork: a daughter’s right to a birth share in joint family property depended on the state in which the family property lay, and the national rule arrived only when Parliament amended the central Act. The same mechanics govern any future state experiment in the field, and they impose a discipline on commentary. A state reform of personal law is neither automatically valid because the subject is concurrent nor automatically void because a central Act exists; its fate turns on the content of the conflict and the use of the assent route, and the Uttarakhand code’s passage through presidential assent is part of its legal design rather than a ceremonial extra, since a code replacing central statutes within a state could not otherwise withstand the repugnancy rule.

Which law applies to a person: the classification question

Before any question of substance arises, a court must assign the parties to a system, and the rules of assignment are themselves a body of doctrine. The starting point is birth and parentage: a child born to Hindu parents is governed by Hindu law, a child born to Muslim parents by Muslim law, and so on. Domicile matters at the edges, because the personal law statutes frame their application partly in terms of persons domiciled in India, and a person who leaves the country may carry their personal law with them for some purposes while falling under another system for others. Conversion changes the assignment, and the courts’ working rule is that a genuine conversion to a religion subjects the convert to the law of the adopted religion for the future, a rule with sharp limits: conversion does not dissolve an existing marriage, does not retrospectively alter succession that has already opened, and, as Sarla Mudgal established in the criminal context, cannot be used as a device to acquire a second spouse while the first marriage subsists. The Act of 1850 already mentioned protects the convert’s property and inheritance from forfeiture, so the legal consequences of conversion are deliberately asymmetrical: status follows the new faith, vested property rights survive, and an existing marriage survives too.

How does a court decide which personal law applies to a person?

It begins with the religion of the parties, proved like any other fact, and applies the statutory definitions. For the Hindu code statutes the definition is expansive: Hindus by religion, Buddhists, Jains and Sikhs, converts to those religions, children of mixed parentage brought up in the community, and any domiciled person who is not Muslim, Christian, Parsi or Jew.

That residual clause deserves emphasis because it reverses the assumption many readers bring to the subject. The Hindu Marriage Act of 1955, by Section 2, applies to Hindus in any of their forms and developments, to Buddhists, Jains and Sikhs, to converts, and to a legitimate or illegitimate child one of whose parents falls within the definition where the child is brought up as a member of that community; and it then provides that it applies also to any other person domiciled in the territories to which the Act extends who is not a Muslim, Christian, Parsi or Jew by religion. A person of no religion, or of a small faith without its own code, who is domiciled in India is therefore swept into the Hindu code statutes by default unless one of the named exclusions applies, while the same statutes expressly do not apply to members of Scheduled Tribes within the meaning of the Constitution unless the central government directs otherwise by notification. Classification litigation, disputes about whether a community is Hindu or a separate faith, whether a marriage was contracted under one system or another, whether a reform movement such as the Lingayat or the Brahmo tradition falls inside or outside the statutory fold, recurs throughout the case law because the answer determines the entire applicable law. The Brahmo Samaj’s history illustrates the stakes: marriages within the movement were first validated by the Act of 1872 precisely because Brahmos were not accepted as Hindus for marriage purposes, and later case law treated the community as within the Hindu fold for succession, so the same community stood outside one statute and inside another.

Two further classification problems recur often enough to deserve statement. The first concerns the children of mixed marriages. Where parents belong to different systems, the child’s governing law is determined in practice by the community in which the child is brought up and the faith in which the child is raised, a test the statutory definition of the Hindu code partly codifies by covering a child one of whose parents is within the definition where the child is brought up as a member of that parent’s community or tribe. The second concerns the sincerity and form of conversion. The courts have held that conversion to Hinduism requires no particular ceremony where the community accepts the convert, the Supreme Court so holding in Perumal v. Ponnuswami in 1971, and that a conversion adopted as a device, without belief, to defeat a subsisting marriage or a prosecution for bigamy will be disregarded for the purpose it was meant to serve. Territory adds one celebrated peculiarity: in Puducherry, descendants of those who, under French rule, formally renounced the French Civil Code’s opposite number, the renoncants, elected to be governed by their personal law, while those who did not renounce remained under the French civil law the territory retained, so that within one small Union territory the two great organising principles of this article, election and assignment, have coexisted by recorded individual choice for over a century.

The classification question has a denominational variant that has occupied the Supreme Court at intervals: when is a movement a separate religion entitled to its own law, and when is it a denomination within a larger faith and therefore inside that faith’s code? In Bramchari Sidheswar Shai v. State of West Bengal in 1995, the Court held that the Ramakrishna Mission, notwithstanding its distinct organisation and its claim to be a separate religion, was a religious denomination within Hinduism, with the consequence that its institutions stood within the Hindu fold for the purposes in issue. The Ananda Marga litigation raised the cognate question from the other side, a movement claiming denominational status within Hinduism to protect its own practices, which the Court recognised while holding the particular practice in dispute not essential to the faith. The stakes of these classifications are the stakes of this whole section: a finding of separate religion takes a community toward its own personal law or toward the residual categories, while a finding of denomination keeps it inside an existing code, and the movements that litigate the question understand precisely what turns on it, since governance of their institutions, the application of reform legislation and the law of their members’ marriages and inheritances all follow the answer.

The religion clauses and the power to reform

The constitutional framework around personal law is completed by the provisions on religious freedom, and the critical point about them is that they were drafted with personal law in view. Article 25 guarantees freedom of conscience and the right freely to profess, practise and propagate religion, subject to public order, morality and health and to the other provisions of the fundamental rights chapter. The same article then authorises the state to regulate or restrict economic, financial, political or other secular activity which may be associated with religious practice, and, in a clause aimed squarely at this field, provides that nothing in the article shall prevent the state from making any law providing for social welfare and reform or the throwing open of Hindu religious institutions of a public character to all classes and sections of Hindus. An Explanation to the article provides that the reference to Hindus in that reform clause includes persons professing the Sikh, Jaina or Buddhist religion, the same grouping the Hindu code statutes would later adopt. Article 26 gives every religious denomination the right to manage its own affairs in matters of religion, again subject to public order, morality and health. Article 29 protects the right of any section of citizens having a distinct language, script or culture to conserve it. Read together, these provisions do not answer the reform question; they frame it. Religious practice is protected, denominational self-management is protected, cultural conservation is protected, and legislative power to reform in the name of social welfare is expressly preserved against the argument that the protection of practice disables it.

Two provisions from the fundamental rights chapter itself complete the frame. Article 13 declares that all laws in force in the territory of India immediately before the commencement of the Constitution shall be void to the extent of their inconsistency with fundamental rights, and defines law, in Article 13(3)(a), to include any ordinance, order, bye-law, rule, regulation, notification, custom or usage having in the territory of India the force of law. Article 372 continues existing laws in force until altered or repealed. The juxtaposition produced the field’s central doctrinal puzzle. If custom or usage having the force of law is law for the purposes of Article 13, and personal law is substantially custom, usage, text and precedent, then pre-constitutional personal law inconsistent with fundamental rights should be void to the extent of the inconsistency. Whether that syllogism works is the question the next section examines, because a great deal turns on it: if it works, every rule of uncodified personal law is open to an equality challenge; if it does not, only the rules a legislature has enacted can be challenged, and the rest can be changed only by legislation.

One doctrine mediates between the religion clauses and the personal law field, and an aspirant is expected to know it. In the Shirur Mutt case of 1954, Commissioner, Hindu Religious Endowments v. Sri Lakshmindra Thirtha Swamiar, the Supreme Court held that the protection of Article 25 and Article 26 extends to rituals and observances that are essential and integral to a religion, judged by the doctrines of the religion itself, and not to every activity a community associates with its faith. The essential practices test became the gate through which claims of religious protection must pass, and it has been applied, praised and criticised ever since: applied, in cases from temple administration to the entry of women into places of worship; praised, as the instrument that lets a court protect the core of a faith without disabling reform of its secular accretions; criticised, on the ground that it makes judges into theologians, deciding which parts of a religion are essential with a confidence the religions themselves do not always share. In the personal law field the test operates one step removed: a rule challenged as violating religious freedom, or defended as protected by it, is first sorted by whether the practice it governs is essential to the faith, and the sorting frequently decides the case before the reform power in Article 25(2) is even reached. The temple entry litigation of 2018 turned in part on exactly that sorting, which is why its opinions, and the later reference of aspects of the question to a larger bench, belong to the doctrinal core of this subject and not to its margins.

The doctrine that decides what can be challenged: Narasu Appa Mali and its long shadow

The question was answered within two years of the Constitution, and the answer has never been squarely reversed. The Bombay High Court was asked to strike down the Bombay Prevention of Hindu Bigamous Marriages Act of 1946, a provincial statute that made bigamy an offence among Hindus while leaving other communities untouched; the challenge argued discrimination. In State of Bombay v. Narasu Appa Mali, reported at AIR 1952 Bom 84, a bench of Chief Justice Chagla and Justice Gajendragadkar upheld the statute as a measure of social reform. On the doctrinal question, the court held that personal law is not law in force within the meaning of Article 13(1), reasoning that the framers, who knew how to mention personal law expressly when they wished to, had not included it, and that the expression laws in force referred to laws enacted by legislatures and the like. The two judges differed on one part of the ground: the Chief Justice was inclined to treat custom or usage as falling within the definition of law in Article 13, while Justice Gajendragadkar held that uncodified personal law, custom included, stood outside it. On the conclusion that mattered, that the personal law of the parties could not be struck down for inconsistency with fundamental rights, the bench spoke with one voice.

The judgment contains a second strand that later reform legislation would repeatedly invoke. The bench treated the bigamy statute as social reform legislation of the kind Article 25(2)(b) expressly saves, and declined to treat polygamy as an integral part of the Hindu religion that the state was disabled from regulating, distinguishing between religious belief and practices the state may reform in the interest of social welfare. That distinction, between the protected core of a faith and the reformable practices associated with it, is the same sorting the essential practices doctrine would formalise two years later in the Shirur Mutt case, and its appearance here, in the field’s founding doctrinal decision, shows the two doctrines growing from a single root. The 1952 court was therefore reformist and abstentionist at once: reformist about the legislature’s power, which it upheld in wide terms, and abstentionist about the judiciary’s power, which it confined by holding the uncodified law beyond the reach of the voiding clause. Much of the later confusion about the case comes from reading only one of its two strands.

The consequences of that conclusion structure the whole field, and they are worth stating plainly. A provision of a codified statute, being a law made by a legislature, may be challenged under Part III and struck down, and provisions of the personal law statutes have been. A rule of uncodified personal law, resting on text, commentary and precedent rather than enactment, cannot on the 1952 reasoning be challenged at all, however unequal its operation, because it is not law in force for the purposes of the voiding clause. The same rule of substance is therefore reviewable or unreviewable depending on its form. Litigation strategy in the field has followed from this ever since: a challenger looks for a statutory hook, a provision that touches the practice, because the hook converts an untestable rule into a testable law. The maintenance litigation that produced the Shah Bano judgment in 1985 travelled exactly that route, resting on Section 125 of the Code of Criminal Procedure, a religion-neutral provision of a general code, rather than on any rule of Muslim law; and the judgment itself, delivered by a Constitution Bench of five judges under Chief Justice Y. V. Chandrachud, held that the provision applied to a divorced Muslim woman because it was a general law of the land, not a rule of her personal law.

The authority of the 1952 doctrine has been doubted at the highest level without being displaced. In Shayara Bano v. Union of India in 2017, the case of the instantaneous divorce, a five-judge bench set aside the practice of talaq-e-biddat by a majority of three to two. Justice Nariman, writing for himself and Justice Lalit, reasoned that the practice was regulated by the Muslim Personal Law (Shariat) Application Act of 1937, which directed that the rule of decision in questions of dissolution of marriage shall be Muslim personal law; the practice therefore fell to be tested as law under Article 13, and it failed the test of manifest arbitrariness under Article 14. That reasoning travelled through the statutory hook and did not need to disturb the 1952 case, whose correctness Justice Nariman nonetheless doubted, recording that it was unnecessary to decide whether the judgment was good law. The dissent of Chief Justice Khehar, with Justice Abdul Nazeer, treated the practice as a matter of personal law and religious practice beyond that route. A year later, in the temple entry litigation, Indian Young Lawyers Association v. State of Kerala in 2018, Justice Chandrachud’s opinion addressed the 1952 doctrine directly and held that to immunise custom, usage and personal law from constitutional scrutiny would deny the primacy of the Constitution, observing that the judgment required reconsideration. These are separate and concurring opinions doubting a High Court decision that only a considered Supreme Court ruling can displace. The accurate statement of the position is the careful one: the doctrine of 1952 remains the operative starting point, it has been doubted by judges of the Supreme Court in terms that weaken its authority, and it has not been overruled. The position is unsettled, not resolved in either direction, and any account that reports it as settled, whether by saying personal law is immune from the Constitution or by saying the immunity has been abolished, goes beyond the record.

The doctrine’s later career shows it being used as a reason for judicial abstention as much as for decision. In Ahmedabad Women Action Group v. Union of India in 1997, the Supreme Court was asked to declare void a set of personal law rules, including polygamy and unilateral divorce practices, as offending Articles 14, 15 and 21. The Court declined, holding that the matters were for the legislature and not for judicial invalidation, and observing that the removal of personal law disparities by judicial order was beyond the appropriate reach of the writ jurisdiction in that form. The decision is the abstentionist pole of the field: even rules whose inequality was fully argued were left to the political process, and the petitioners were directed, in substance, to Parliament. Read with the 1952 doctrine, the 1997 refusal completes a pincer: uncodified personal law cannot be struck down because it is not law in force, and the courts will in any event remit its reform to the legislature. The Danial Latifi decision of 2001 shows the third judicial technique in the field, neither invalidation nor abstention but construction: confronted with a statute widely read as confining a divorced Muslim woman’s claim against her former husband to the iddat period, a Constitution Bench upheld the Act by construing its central phrase, a reasonable and fair provision, to include a provision for her future needs, made within the iddat period, so that the statute survived the equality challenge by being read to deliver substantially what the challenge demanded. Between the three techniques a court in this field always has a choice, and the pattern of choices over seventy years, abstention for the uncodified, construction for the codified where construction is possible, invalidation reserved for provisions that admit of neither, is the closest thing the field has to a judicial philosophy.

The practical teaching of the doctrine for a reader of the statutes is a habit of attention to form. When a rule in this field is described as unjust or indefensible, the legally operative question is where the rule lives. If it lives in an Act, it can be challenged, amended or repealed, and the argument belongs in court or in the legislature as a matter of ordinary law reform. If it lives in the uncodified stratum, the court route is blocked or at best uncertain on the 1952 reasoning, and the realistic routes are legislative codification, which converts the rule into testable law, or the slow movement of precedent within the personal law itself, where courts have on occasion read a rule in the light of its own sources and declined to apply its harsher historical forms. The field’s reform history shows all three routes in use, and the statutes examined next cannot be understood without seeing which route produced each of them.

The statutes, community by community

The codification map is asymmetric, and the asymmetry is the single most instructive fact in the field. One community’s law was codified comprehensively after independence, in a project whose drafting and passage history is told in the history of the Hindu Code Bills and their passage. Other communities received statutes at different times, from different hands, for different reasons, and in one case the governing law remains substantially uncodified. Taking the communities in turn shows the pattern.

The Hindu code consists of four statutes. The Hindu Marriage Act of 1955, Act 25 of 1955, in force from 18 May 1955, codified marriage and divorce: it imposed monogamy, prescribed conditions and ceremonies for a valid marriage, recognised customary rites, and introduced judicial separation and divorce into a system in which classical law had treated marriage as indissoluble. The Hindu Succession Act of 1956, Act 30 of 1956, in force from 17 June 1956, codified intestate succession and curtailed the classical joint family by stages that later amendments, state and central, extended. The Hindu Minority and Guardianship Act of 1956, Act 32 of 1956, in force from 25 August 1956, codified guardianship for Hindu minors and declared itself supplementary to the general guardianship statute of 1890. The Hindu Adoptions and Maintenance Act of 1956, Act 78 of 1956, in force from 21 December 1956, codified adoption, which it confined to Hindus, and placed the obligations of maintenance on a statutory footing. Four features of the code define the modern Hindu law. It applies to the wide statutory class already described, Buddhists, Jains and Sikhs included. It overrides inconsistent texts, rules and customs on the subjects it covers, so codification here meant displacement of the uncodified stratum, not mere restatement. It retains internal plurality, recognising custom for marriage ceremonies and for certain other purposes, so a codified system still runs on custom at defined points. And it was built by a Parliament in which the community it governed held a large majority, a fact about consent that the reform debate returns to repeatedly. Sikhs also have the Anand Marriage Act of 1909, Act 7 of 1909, which validates marriages by the Anand ceremony and was amended in 2012 to provide for their registration, a small statute that coexists with the code because a Sikh marriage is equally valid under the Marriage Act itself.

What did codification change for the communities it covered?

It changed the source of the law before it changed the content. A rule in a code can be amended by a legislature in a single session and tested against the Constitution; a rule in the uncodified stratum moves only by precedent or by the codification that displaces it, which is why uncodified communities inhabit a different reform world.

Muslim personal law presents the opposite configuration: a small number of statutes surrounding a large uncodified core. The Muslim Personal Law (Shariat) Application Act of 1937, Act 26 of 1937, is a statute about sources rather than substance. Its Section 2 provides that, notwithstanding any custom or usage to the contrary, in questions regarding intestate succession, the special property of females, marriage, dissolution of marriage including talaq, ila, zihar, lian, khula and mubaraat, maintenance, dower, guardianship, gifts, trusts and wakfs, the rule of decision where the parties are Muslims shall be the Muslim personal law, the Shariat. The Act thus displaced custom in favour of scriptural law across much of the field, a reform demanded by Muslim legislators of the period against the customary regimes, some of them markedly unfavourable to women on inheritance, that governed many Muslim communities in practice. Its Section 3 allows a Muslim to declare that the Act’s rule shall extend also to adoption, wills and legacies, matters otherwise left to custom or choice. Beyond the Application Act, the substance remains largely uncodified, drawn from the Hanafi school for most Indian Sunnis and from Ithna Ashari law for Shias, as stated in the classical texts and the precedent built on them. Parliament has intervened at points of acute controversy. The Dissolution of Muslim Marriages Act of 1939, Act 8 of 1939, gave Muslim women statutory grounds to obtain a decree of dissolution, and removed the rule that a wife’s renunciation of Islam itself dissolved the marriage. The Muslim Women (Protection of Rights on Divorce) Act of 1986, Act 25 of 1986, answered the Shah Bano judgment by prescribing its own scheme of provision and maintenance for a divorced woman within and after the iddat period, a scheme the Supreme Court later construed in Danial Latifi v. Union of India in 2001, upholding the Act while reading it to require a reasonable and fair provision for the divorced woman’s future, made within the iddat period. The Muslim Women (Protection of Rights on Marriage) Act of 2019, Act 20 of 2019, assented to on 31 July 2019 and deemed in force from 19 September 2018, gave statutory effect to the Shayara Bano result by declaring a pronouncement of instant triple talaq void and illegal and making it an offence. Each of these statutes is owned by its own specialist article; their collective significance here is the pattern they form: episodic, controversy-driven enactment at the margins of an uncodified system, the mirror image of the comprehensive codification of 1955 and 1956.

The economic institutions inside the uncodified Muslim law deserve the same structural attention as its divorce law, because they carry much of its practical protection for women. The dower, the mehr, is a sum the husband is bound to pay the wife by virtue of the marriage contract itself, fixed at the contract or assessed by law where the parties fixed none, payable in part promptly and in part deferred to the dissolution of the marriage, and enforceable by the wife as a debt, with a right in classical law to retain her deceased husband’s property in lieu of unpaid dower until her claim is satisfied. Whatever the system’s other asymmetries, the mehr is a mandatory financial incident of marriage that no party can contract out of the wife’s disfavour below the legal minimum the courts will imply, and comparisons between the systems that omit it understate the protection the uncodified law builds in. The institutional fringe of the system is statutory in the older style: the Kazis Act of 1880, Act 12 of 1880, empowers state governments to appoint kazis for defined local areas to perform marriages and other functions, a colonial recognition that the community’s offices would be serviced but not directed by the state. And where the uncodified law provides no adoption, Muslim families have for generations used the guardianship statute of 1890 to take a child into their care with the court’s authority, acquiring custody and responsibility without the parentage adoption creates, the distinction the adoption article in this series works through in full.

Christian family law is codified, but by the colonial state rather than by the republic. The Indian Christian Marriage Act of 1872, Act 15 of 1872, governs the solemnisation of marriages to which at least one party is a Christian, prescribing who may solemnise, the notices and certificates required and the registers to be kept. The Divorce Act of 1869, Act 4 of 1869, governs dissolution, nullity, judicial separation and the matrimonial relief of Christians; in its original form its grounds were markedly unequal, a husband being able to sue on adultery alone while a wife had to prove adultery aggravated by a further offence, and the inequality stood for over a century until the Indian Divorce (Amendment) Act of 2001, Act 51 of 2001, substituted equal grounds for both spouses and introduced dissolution by mutual consent. Succession for Christians is governed by the Indian Succession Act of 1925, and the Supreme Court confirmed in Mary Roy v. State of Kerala in 1986 that Christians in Kerala take under that Act rather than under the Travancore Christian Succession Act of 1916, a ruling that substantially improved the shares of Syrian Christian women in their fathers’ estates. Christians have no personal statute of adoption, and adoption for a Christian family runs through the secular route described below. The community’s law thus demonstrates a third pattern: complete codification, achieved early, frozen for long periods, and amended late.

Parsi family law follows the same pattern in miniature. The Parsi Marriage and Divorce Act of 1936, Act 3 of 1936, which replaced an Act of 1865, codifies marriage and divorce for Parsis and constitutes special Parsi Matrimonial Courts, in which the presiding judge sits with delegates drawn from the community, an institutional survival of the principle that a community’s family disputes are heard with the community present. Parsi intestate succession is governed by a special set of provisions within the Indian Succession Act of 1925, notable among other things for giving the widow and widower defined shares alongside children and for treating the parents of the deceased within the scheme. Guardianship and adoption follow the general pattern: the guardianship statute of 1890 applies, and adoption, which classical Parsi law did not provide, is available through the secular route.

The Jewish community has no personal law statute at all. Marriages are contracted by religious rite and recognised by the courts, matrimonial relief has been granted by the courts working from the community’s law and from general principles of justice, equity and good conscience, and succession is governed by the Indian Succession Act of 1925, whose intestacy provisions do not exclude Jews. The community’s small size explains the absence of legislation, and its position in the map is a reminder that the system’s categories were fixed by the political weight of communities in the nineteenth century, not by any principle that every faith receives a code.

The final element is the route that belongs to no community. The Special Marriage Act of 1954, Act 43 of 1954, assented to on 9 October 1954 and in force from 1 January 1955, provides a form of civil marriage available to any two persons regardless of religion, solemnised before a marriage officer after public notice, with divorce, nullity, maintenance and succession governed by the Act and by the Indian Succession Act, subject to a statutory exception preserving the Hindu Succession Act where both parties belong to the classes that Act covers. The statute’s own depth, its notice regime and the litigation its procedures have generated, belong to the pillar article on the Special Marriage Act of 1954; its function in the map is to be the standing alternative, the proof that the personal law system is, for marriage at least, a default rather than a compulsion, since any couple may step outside their assigned laws by marrying under it. The Indian Succession Act of 1925, Act 39 of 1925, completes the secular side of the map: a consolidating statute whose intestacy provisions govern Christians, Parsis, Jews and those married under the Special Marriage Act while expressly standing aside for Hindus, Muslims, Buddhists, Sikhs and Jains, whose testamentary law it partly governs and for Muslims does not govern at all, Muslim wills remaining subject to the uncodified law and its limits on testamentary freedom.

Two details of the Application Act of 1937 repay notice before the table, because they display the statute’s character better than any summary. The first is its agricultural land saving: Section 2 opens by excluding questions relating to agricultural land from its list, a carve-out reflecting the provincial politics of land in the 1930s, with the result that succession to agricultural holdings among Muslims continued in many regions to be governed by the customary law the Act elsewhere displaced, and in places still interacts with state tenancy legislation. The second is what the Act did not do: it laid down no rule of substance at all. It is a choice-of-law statute, a direction to courts about which body of rules to apply, and its brevity, six sections in its operative part, contrasts with the bulk of the law it set in motion. The contrast generalises. The most consequential personal law statutes are often the shortest, because their function is to assign questions to systems rather than to answer them.

Marriage formation, the gateway to every system, displays the diversity the assignment produces. A Hindu marriage is solemnised by customary rites, of which the saptapadi, the taking of seven steps before the sacred fire, is the binding element where it is part of the applicable custom, and the statute treats the ceremony as constitutive: no registration creates the marriage, registration being a record of a marriage the rites have made. A Muslim marriage, the nikah, is in juristic analysis a civil contract, constituted by offer and acceptance in the presence of witnesses, with the dower, the mehr, as an incident fixed by agreement or by law. A Christian marriage under the Act of 1872 is constituted by solemnisation before an authorised person, a minister of religion, a marriage registrar or a person licensed for the purpose, within a framework of notices, certificates and registers that makes the state a participant from the start. A Parsi marriage is constituted by the Ashirvad ceremony performed by a priest before two Parsi witnesses. A marriage under the Special Marriage Act is constituted by the civil ceremony before the marriage officer and the entry in the marriage certificate book. On the same human event the systems therefore distribute constitutive force very differently, between rite, contract, authorised solemnisation and state ceremony, and the Supreme Court’s direction in Seema v. Ashwani Kumar in 2006, that marriages of all communities should be compulsorily registrable, with the states directed to frame rules, was an attempt to lay a common evidentiary floor under the diversity without disturbing the constitutive rules themselves, an attempt whose implementation through state rules remains uneven in coverage and consequence.

The Hindu code’s own territorial and personal edges repay a moment’s attention, because they show even the most complete codification leaking at its borders. The Marriage Act as enacted extended to the whole of India except the then state of Jammu and Kashmir, and it has never extended to Goa, where the Portuguese code continued, so that a Hindu domiciled in Goa marries, divorces and inherits under the Goan system while a Hindu domiciled across the border in Maharashtra lives under the code; the position of the erstwhile state of Jammu and Kashmir changed with the reorganisation of 2019, by which the central family statutes were extended to the successor Union territories. Within its territory, the Act’s application to Scheduled Tribes is switched off by default and switched on only by notification, a provision that has left many tribal communities governed by their own law of marriage and succession while their neighbours live under the code, and has generated its own line of disputes about whether a community has become Hinduised enough, in the language of the cases, to be treated as Hindu for the statute. At the other edge stand the converts and the children of converts, whose classification the courts decide by the community’s acceptance and the person’s observance rather than by formal rite alone. A code, in short, does not abolish the classification question; it relocates it to the code’s own boundaries, where it continues to be litigated.

Codification projects for the uncodified systems form a literature of their own, and its unfinished character is itself evidence about the politics of the field. Within the Christian community, organisations of the churches prepared draft bills to replace the Acts of 1869 and 1872 with a single modern Christian marriage and matrimonial causes statute, and drafts circulated through the law ministry and the Law Commission for years without reaching introduction, the 2001 amendment arriving instead as a repair of the old Act rather than its replacement. Within the Muslim community, the codification question divides differently: the Personal Law Board has resisted codification as such, while the Bharatiya Muslim Mahila Andolan published a draft Muslim family law of its own, drawn from the Quran and constitutional values, proposing among other things a regulated, arbitrated model of divorce and the abolition of unilateral extra-judicial forms, a draft whose significance lies less in its prospects than in its authorship, since it relocates the demand for a code from the state to the community’s women. The Hindu code itself supplies the standing precedent that comprehensive codification of a living religious law is possible in India, and the standing warning that it consumed a decade, a constituent assembly’s worth of political capital, and the resignation of the law minister who steered it. Which of those two lessons a given codification project should draw is the question its sponsors and opponents are really arguing about.

Restitution of conjugal rights: the remedy every system shares

One remedy appears in system after system with a persistence that makes it the field’s best specimen of a shared institution differently housed. The Hindu Marriage Act provides, in its Section 9, that a spouse whose partner has withdrawn from the society of the other without reasonable excuse may petition for restitution of conjugal rights, and the Special Marriage Act and the Parsi statute carry corresponding provisions, while the Divorce Act gives the Christian spouse the same relief and Muslim law reaches a cognate result through suits for restitution that the courts entertained from the classical authorities. The remedy’s career in constitutional litigation is the instructive part. In T. Sareetha v. T. Venkata Subbaiah in 1983, the Andhra Pradesh High Court struck down Section 9 of the Hindu Marriage Act as a violation of the rights to privacy and human dignity, reasoning that a decree compelling cohabitation, backed by attachment of property on disobedience, treated the person as a means. The Delhi High Court took the opposite view, and in Saroj Rani v. Sudarshan Kumar Chadha in 1984 the Supreme Court upheld the provision, treating the decree as an inducement to reconciliation serving a social purpose, while observing that it functions in practice as a step toward divorce, since a spouse who defies it for the statutory period hands the other a ground of dissolution. The remedy thus survives across the codes in a form its critics regard as coercive and its defenders as conciliatory, largely unused for its stated purpose and heavily used as a procedural lever, and its history compresses the whole field’s method into one provision: a classical institution, codified without examination in the 1950s, tested against the Constitution once the rights framework matured, saved by construction and by a benign account of its purpose, and left in the statute book to do work quite different from the work its text describes.

Divorce across the systems: one institution, four architectures

No subject shows the plurality of the field more concretely than the ending of a marriage, because the systems built genuinely different machines for it. The Hindu code treats divorce as a judicial act available on fault grounds stated in the statute, to which the Marriage Laws (Amendment) Act of 1976, Act 68 of 1976, added divorce by mutual consent and recast the grounds of cruelty and desertion in the form the courts have applied since; the theory is that a marriage the statute constitutes, the court dissolves, on proof. The Special Marriage Act mirrors that architecture for the civil route, with its own consent provision and a set of additional grounds for a wife. The Parsi statute routes the same judicial model through its special courts with delegates, and acquired its mutual consent provision by the amendment of 1988. The Divorce Act carried the oldest model of all, an ecclesiastical inheritance in which dissolution was confined for over a century to narrow and unequal fault grounds, until the amendment of 2001 equalised the grounds and admitted consent. Beside these judicial machines stands the uncodified Muslim law, in which divorce was classically an act of the parties rather than of a court: the husband’s talaq in its regulated forms, dissolution by agreement in khula and mubaraat, the wife’s delegated and negotiated routes, and, since the Act of 1939, her statutory suit for a decree on grounds the Act enumerates. The legislature’s interventions in that system have been characteristically surgical, voiding the instant form of talaq in 2019 while leaving the architecture of extra-judicial divorce standing. A reform argument conducted at the level of divorce in India therefore misses its object: there is no single institution to reform, only a set of exit mechanisms whose costs fall differently on husbands and wives in each system, and the comparative question a serious reader asks is not which system is strictest but in which system a spouse who needs an exit, and lacks money, evidence and family support, can actually obtain one. On that question the systems’ reputations and their operation diverge in both directions, which is why the specialist articles treat each machine separately.

Who is governed by what: the codification table

The table below compresses the map into a single object. Read across a row to see one community’s law; read down a column to see which subjects the legislatures have codified and which they have left alone. The final column records the fact that organises the whole article: whether the governing law on the row is codified, uncodified, or a mixture of the two.

Community or route	Marriage	Divorce	Maintenance	Adoption	Guardianship	Succession	Codified or uncodified
Hindus, with Buddhists, Jains and Sikhs	Hindu Marriage Act 1955	Hindu Marriage Act 1955	Hindu Adoptions and Maintenance Act 1956	Hindu Adoptions and Maintenance Act 1956	Hindu Minority and Guardianship Act 1956 with the Act of 1890	Hindu Succession Act 1956	Codified
Muslims	Uncodified law, with the Application Act 1937 directing its use	Uncodified law; wives’ suits under the Act of 1939; instant talaq void under the Act of 2019	Act of 1986 for divorced women; general law besides	No personal statute; the secular adoption route applies	Uncodified law with the Act of 1890	Uncodified law under the Application Act 1937	Mostly uncodified
Christians	Indian Christian Marriage Act 1872	Divorce Act 1869, as amended in 2001	Divorce Act 1869 and general law	No personal statute; the secular adoption route applies	Guardianship and Wards Act 1890	Indian Succession Act 1925	Codified, by colonial statutes
Parsis	Parsi Marriage and Divorce Act 1936	Parsi Marriage and Divorce Act 1936	Parsi Marriage and Divorce Act 1936	No personal statute; the secular adoption route applies	Guardianship and Wards Act 1890	Indian Succession Act 1925, Parsi provisions	Codified
Jews	Custom and religious rite; no statute	Court relief on general principles; no statute	General law	The secular adoption route applies	Guardianship and Wards Act 1890	Indian Succession Act 1925	Uncodified
The secular route, open to all	Special Marriage Act 1954	Special Marriage Act 1954	Special Marriage Act 1954 and general law	Juvenile Justice Act adoption machinery	Guardianship and Wards Act 1890	Indian Succession Act 1925, with a statutory exception for Hindu code couples	Codified and elective

Two readings of the table repay the attention of any reader who intends to argue about reform. The first is horizontal: no two communities stand in the same relation to the legislature, so a proposal framed for one row does not transfer to another, and the phrase personal law reform conceals at least four distinct legislative tasks. The second is vertical: adoption and guardianship are the columns where the personal law system is thinnest, and it is there that general statutes have done most of the work, a pattern the next section develops.

The secular overlays: general law inside the personal law field

No resident of India lives wholly inside a personal law, because a set of general statutes cuts across the whole field and applies to everyone regardless of community. These overlays are where the territorial remainder of the colonial settlement meets the personal core, and several of the field’s most consequential rules live there rather than in the community statutes.

Which parts of family life does personal law not govern at all?

The criminal law of the family, the protection statutes and the floor of maintenance are general. Bigamy is an offence where a personal law forbids a second marriage; child marriage is prohibited for every community; dowry is barred by a statute of 1961 without exception; and the protection statute of 2005 gives women the same orders against violence.

The maintenance example shows the overlay at work in its most litigated form. The criminal procedure codes, the Code of 1973 in Section 125 and its successor code in the same function, empower a magistrate to order a person of sufficient means to maintain a wife unable to maintain herself, children and dependent parents, on a summary procedure designed to prevent vagrancy rather than to settle matrimonial rights. Because the provision is part of a general code, the Supreme Court could hold in 1985 that it applied to a divorced Muslim woman without touching any rule of Muslim law, and because it is summary and secular, it coexists with the personal law remedies rather than replacing them; a claimant may hold rights under both and pursue the one that serves. The child marriage overlay works in the other direction: the Prohibition of Child Marriage Act of 2006, Act 6 of 2007, in force from 1 November 2007, makes a child marriage voidable at the option of the party who was a child and void in aggravated cases, and it does so for every community, overriding the position under several personal laws that treated a minor’s marriage, once performed, as valid; the courts have repeatedly had to mediate between the overlay and the personal law beneath it, and the overlay has prevailed on the question of the marriage’s enforceability. The Protection of Women from Domestic Violence Act of 2005, Act 43 of 2005, supplies protection orders, residence orders and monetary relief to women in domestic relationships, defined widely enough to include relationships in the nature of marriage, and its remedies are expressly in addition to any other law. The Dowry Prohibition Act of 1961, Act 28 of 1961, completes the standard set.

Adoption and guardianship show the overlay becoming the main road. The Guardians and Wards Act of 1890, Act 8 of 1890, is a general statute under which a court appoints guardians of the person and property of any minor, directing itself by the minor’s welfare and by the personal law of the minor so far as it speaks; for Hindus the Act of 1956 supplements it, for other communities it works alongside the uncodified law. Adoption was for over a century available by right only to Hindus under their code, since classical Muslim, Christian, Parsi and Jewish law in India provided no adoption. The Juvenile Justice legislation, in its successive forms and in the form given by the Act of 2015, built a secular adoption system administered through specialised agencies and a central authority, open to persons of every religion, and in Shabnam Hashmi v. Union of India in 2014 the Supreme Court confirmed that a person may adopt under that legislation regardless of personal law, while declining to declare adoption itself a fundamental right. The result is that the most tradition-bound subject in the classical laws is, in practice, governed for many families by a welfare statute of general application, and the personal law position survives mainly as a statement about what the religious law does not provide. The wider frame within which these overlays protect women across communities is mapped in the guide to women’s rights legislation in India.

Registration is the overlay still under construction. The Supreme Court’s direction of 2006 that the states frame rules for compulsory registration of marriages has produced a patchwork of state registration regimes of varying coverage, some folded into general registration statutes and some standing alone, and the Law Commission added its recommendation in a report of 2017 that a central law make registration of marriages compulsory without disturbing the validity conferred by religious rites. The distinction the reform preserves is the constitutive one drawn earlier: registration evidences a marriage, it does not create it, and a failure to register exposes the parties to penalty and to serious evidentiary difficulty without dissolving a marriage the rites have validly made. The practical consequence falls hardest where proof matters most, on a widow claiming succession or maintenance whose marriage was never recorded, which is why registration, the least theological subject in the field, is among the most consequential for women in every community.

Procedure is an overlay too. The Family Courts Act of 1984, Act 66 of 1984, created a tier of courts charged with deciding matrimonial and family disputes by a procedure oriented to settlement, with simplified evidence rules and the assistance of counsellors, and the personal law causes of the whole country are increasingly heard in those courts where they have been established. The substantive law remains plural; the forum is progressively common. A reader who wants to know how the system feels in use should attend to that divergence, because it explains how a plural law can nonetheless produce a recognisably national litigation culture.

Succession across the systems: the deepest divergence

If divorce shows the systems building different machines, succession shows them answering different questions. The classical Hindu law asked how the family’s property, held in significant part as a coparcenary in which sons acquired an interest by birth, should devolve, and the Act of 1956 answered with a scheme of Class I and Class II heirs for a man’s separate property, a parallel scheme for a woman’s property that the courts and the amendment of 2005 progressively equalised, and the conversion of the coparcenary itself, completed for daughters by that amendment, into a birthright shared by sons and daughters alike. Muslim law asks a different question: how an estate is to be distributed among the Quranic sharers, spouse, parents and daughters among them, whose fixed fractions are stated in the text, with the residue passing to the residuaries and the distant kindred behind them, under a scheme that operates on every death without exception and admits no disinheritance of a sharer. The Indian Succession Act asks a third question for the communities it covers: what order of kinship should take where the deceased has left no will, and answers it with the surviving spouse’s defined share, one third where there are children in the standard Christian case, and equal division among the children of the remainder, with parents and remoter kin succeeding in stated orders behind them. Testamentary freedom completes the divergence. A Hindu, Christian or Parsi testator may in principle dispose of the whole of the self-acquired estate by will, subject in Goa to the legitime; a Muslim testator may bequeath no more than one third of the net estate without the consent of the heirs, the limit the classical law places on the power to divert the Quranic scheme. A reader comparing the systems on women’s shares, the comparison the reform debate makes most often, should therefore compare outcomes across whole schemes rather than single fractions: a daughter’s fixed Quranic share of half a son’s portion operates in a system with no testamentary escape from it, while a daughter’s equal share under the Hindu Act operates in a system where a will can redirect the self-acquired estate, and the systems’ practical generosity to daughters is a function of both rules together.

Above the separate systems sits one unifying power that the courts have taught litigants to invoke across all of them. Article 142 empowers the Supreme Court to pass such decree or make such order as is necessary for doing complete justice in any cause or matter pending before it, and in Shilpa Sailesh v. Varun Sreenivasan in 2023 a Constitution Bench of five judges held that the power extends to dissolving a marriage that has broken down irretrievably, dispensing with the waiting periods and procedural steps the matrimonial statutes prescribe, where the Court is satisfied that the marriage is beyond repair and that dissolution serves complete justice between the parties. The holding operates across the personal law systems because its source is not any of them: a Hindu, Christian, Parsi or civil marriage that reaches the Court in a pending proceeding may be dissolved on the breakdown ground that none of the governing statutes, the uncodified law included, states in terms. The decision has been read narrowly by its defenders, as an exceptional power of the apex court tied to cases before it, and widely by its critics, as the arrival by the judicial door of the breakdown ground that legislatures had declined to enact since the Law Commission first recommended it. Either way it is the clearest modern instance of the pattern this guide has traced throughout: where the plural systems converge too slowly for the case in hand, a general institution, here the constitutional court armed with a general power, supplies the common rule.

The literature of the field records the same layering. For the uncodified law, the practitioner’s working authorities remain the great treatises in the Mulla tradition, restating the law as propositions footnoted to decisions, periodically revised, and treated by courts as persuasive statements of the law they organise. For the codes, the commentary tradition runs section by section, and its bulk is a fair index of the litigation each provision has generated: the definition clauses and the divorce grounds of the Hindu Marriage Act have each accumulated a jurisprudence denser than many entire statutes in this series. Between the treatise and the commentary stands the case law of the Supreme Court, which, because it speaks to all systems from a single bench, has become the field’s informal harmoniser, aligning the reading of parallel provisions across the codes on maintenance, custody and the proof of marriage ceremonies, even where it disclaims any power to unify the substantive law. A researcher who understands why the same maintenance principle appears, in near-identical language, in judgments arising under four different statutes has understood the mechanism by which a plural system acquires a common law without acquiring a common code.

Maintenance and the child: the two subjects where the systems converge

Standing back from the community statutes, two subjects show the systems converging toward common answers by different roads, and the convergence qualifies any simple picture of fragmentation. The first is the maintenance of dependants after family breakdown. Every system in the field obliges a husband to maintain a wife during marriage, and the systems diverge mainly on what survives the end of the marriage and for how long. The Hindu code places the obligation in the maintenance statute of 1956, which gives a wife a right to maintenance including, in defined circumstances, while living separately, and charges the heirs of a deceased person with the maintenance of dependants from the inherited estate. The Divorce Act gives the Christian wife alimony during the suit and permanent alimony after it, modelled on the English practice of its century. The Parsi statute does the same within its own courts. Muslim law obliges maintenance during marriage and through the iddat after divorce, and the Act of 1986 then superimposes its scheme of provision and maintenance for the divorced woman, backed, where the husband and her relatives fail, by the state waqf board. Above all of them sits the summary remedy of the procedure code, available to every wife, child and parent on proof of neglect and inability, and deliberately indifferent to the personal law of the parties. A maintenance lawyer therefore works with a stack of remedies ranked by speed and generosity, and the personal law layer is rarely the layer that decides the outcome in a hurry, whatever its importance to the theory.

The second subject is the child, and here the convergence is driven by a principle the general statute of 1890 carried from the start: in appointing a guardian, the court’s controlling consideration is the welfare of the minor, a consideration to which the personal law of the minor is relevant but subordinate in the modern case law. The Hindu guardianship statute of 1956 named the father the natural guardian of a minor’s person and property and the mother after him, a formula the Supreme Court read in Gita Hariharan v. Reserve Bank of India in 1999 to mean that the mother may act as natural guardian during the father’s lifetime where the father is absent from the child’s care in fact, construing the word after as in the absence of rather than after the lifetime of, and thereby saving the provision from the charge of sex discrimination by interpretation. The technique is the same constructionist one visible in the maintenance cases: where a codified text admits of an egalitarian reading, the courts have preferred it to invalidation. Custody disputes across communities are decided on welfare with a consistency that makes custody the least plural corner of the plural system, and adoption, since the secular machinery described earlier became available to all, has joined it.

Goa: the code that is common but not uniform

One territory in India tests what a single civil code actually looks like in operation. The Portuguese Civil Code of 1867 was extended to Goa by royal decree of 18 November 1869 and took effect there in 1870. When Goa became part of India in December 1961, Section 5(1) of the Goa, Daman and Diu (Administration) Act of 1962 provided that all laws in force immediately before the appointed day should continue in force until amended or repealed by a competent legislature or other competent authority, and the code accordingly continued, its family and succession provisions surviving in substantial part ever since; the central personal law statutes, the Hindu code included, were not extended to the territory. Goa therefore has what no other state has: a single code of family law that applies to residents irrespective of religion, under which marriage is registered before a civil authority, the default property regime between spouses is a communion of assets, and parents must reserve a compulsory portion of their estate for their children, daughters included.

The code is common; it is not wholly uniform, and the qualifications are part of its instruction. Marriages celebrated in church by Catholics have civil effect under arrangements descending from a canonical marriage decree of 1946, so the civil system incorporates a religious ceremony for one community. The communion of assets regime can be displaced by an antenuptial contract, so couples may contract into different property consequences. Older decrees preserved certain usages of the Hindu community of the territory, and special rules historically applied to defined groups within it. Succession has been substantially re-legislated by the territory’s own hand, in the Goa Succession, Special Notaries and Inventory Proceedings Act of 2012, which replaced the code’s succession provisions. The Goan experience therefore supports two conclusions at once, between which the national debate chooses according to taste. It demonstrates that a common code can be administered for a century and a half in a society of several religions without the sky falling, which is the point its admirers press. It also demonstrates that a code called uniform accommodates community-specific provisions and private ordering from the start, which is the point its critics press when they observe that uniformity in practice is a matter of degree. Both conclusions are true of the same instrument, and the evaluation of the model belongs to the debate article rather than to this map.

The Goan code also travels with the Goan. In Jose Paulo Coutinho v. Maria Luiza Valentina Pereira in 2019, the Supreme Court was asked whether the succession of a man of Goan domicile, who had lived and acquired property in Bombay, was governed by the Portuguese Civil Code or by the Indian Succession Act. The Court held that the civil code of Goa governs the succession of Goans domiciled in Goa even in respect of property situated outside the state, reasoning from the code’s character as the personal law of the Goan community in the territory. The decision is doctrinally interesting beyond its facts, because it treats a territorial code as functioning, for those domiciled under it, exactly as a personal law functions for everyone else in this guide: as the law of the person, carried across internal borders, and it confirms that the distinction between territorial and personal law in India is a distinction of organising technique rather than of practical effect.

The Goan property regime deserves a closer statement, because it is the element of the code newcomers find most foreign. Under the communion of assets, which is the default regime where the spouses have made no antenuptial convention, the property acquired by either spouse during the marriage, and in the full form of the regime much that each brought to it, forms a common mass in which each spouse holds an undivided half, administered under rules that restrain either spouse from alienating common property alone. On dissolution, by death or divorce, the mass is divided, and the surviving spouse’s half is separated before the deceased’s estate is computed. The legitime then operates on that estate: a fixed portion, one half of it in the standard case, is reserved to the compulsory heirs, children in the first line, and the deceased’s free power of disposition extends only to the remainder. Daughters take within the legitime on the same terms as sons, which is why the Goan law of succession was, for most of the twentieth century, markedly more favourable to women than the classical Hindu law of the neighbouring states or the uncodified law of several other communities, a comparison the code’s admirers press and its critics answer by pointing to the regimes the code permits couples to contract out of, and to the special provisions, noted earlier, that temper its uniformity for defined groups.

Internal diversity: custom, region, sect and tribe

The table’s rows name communities; the ground truth is finer-grained. Within Hindu law, the classical schools divided the country long before codification, the Mitakshara across most of India and the Dayabhaga in Bengal and Assam, with sub-schools beneath them, and the codifying statutes, while displacing the schools on the subjects they cover, expressly preserved custom at points where local practice was strongest, notably in the ceremonies of marriage and in the prohibited degrees, where a custom permitting a marriage the statute’s schedule would otherwise bar can save it. Within Muslim law, the Hanafi doctrine that governs most Indian Sunnis differs from the Ithna Ashari doctrine of the Shias on inheritance, temporary marriage and other questions, and smaller communities, the Khojas, Bohras and Memons among them, carried customary inheritance regimes into the modern period, some of which the Application Act of 1937 displaced and some of which survived by the interaction of statute and precedent. Matrilineal systems, under which property descended through women, governed the Marumakkathayam communities of Kerala until the state abolished the joint family system there, and continue in modified forms among the Khasi and Garo peoples of Meghalaya. A statement of the form Hindu law requires, or Muslim law provides, is therefore always an abbreviation, and the abbreviation conceals the strongest shared observation in the scholarly literature of both reform camps: that the argument is frequently conducted as though personal laws were uniform within each community, and they are not.

Tribal customary law stands in a distinct constitutional position, protected not merely by judicial recognition of custom but by text. The Fifth Schedule empowers the Governor, in the scheduled areas, to direct that an Act of Parliament or of the state legislature shall not apply, or shall apply with modifications, to a scheduled area, and to make regulations for the peace and good government of such areas, including on the allotment and transfer of land. The Sixth Schedule goes further for the autonomous districts it covers, empowering district councils themselves to make laws on inheritance of property, marriage and divorce, and social customs. Articles 371A and 371G add state-specific protection for Nagaland and Mizoram: no Act of Parliament in respect of religious or social practices, customary law and procedure, or the administration of justice under customary law applies to those states unless the legislative assembly so resolves. The Uttarakhand code’s exclusion of Scheduled Tribes from its scope is a recognition of the same settlement from the other side: the one community category the Constitution textually insulates from general legislation is the one a uniform code, state-made, left out. How tribal customary law is treated in individual family questions is answered among the frequently asked questions below; the architectural point here is that the pluralism of the system is not a single policy but a stack of settlements, colonial, constitutional and scheduled, reached at different times for different reasons.

The tribal settlement also has an institutional working life that a bare statement of the schedules understates. The autonomous district councils of the Sixth Schedule are not consultative bodies on family matters; they are legislatures for them, and the Khasi Hills Autonomous District Council, to take the most legally active example, operates in a society where descent and ancestral property run through the female line and the youngest daughter is the customary custodian of the ancestral house, a system no Indian statute created and none has displaced. Proposals within Meghalaya to restate or alter the customary law of succession, including debates about the position of Khasi women who marry outside the community, are conducted in the councils and the community’s own institutions in the first instance, which is precisely the allocation of authority the Sixth Schedule was designed to produce. Goa supplies the contrasting case of a community-specific usage absorbed into a code: the Portuguese administration codified the usages and customs of the Hindus of the territory in a separate compilation, so that even inside the common code, the plural method survived as a scheduled exception. The pattern across both examples is the one this section has pressed: at every level of the Indian system, the uniform instrument contains a deliberate aperture for the particular community, and the argument about reform is in large part an argument about the size of apertures.

The two standing positions, stated at full strength

Every argument about this field is a movement between two positions, and the discipline this article has imposed on itself throughout, description without adjudication, applies with special force here. Each position is stated as its serious proponents state it.

The reform position begins from the constitutional text. The personal laws, its proponents say, contain rules that treat women less favourably than men in the core transactions of family life: in the grounds and modes of divorce, in the shares of inheritance, in guardianship, where the father is named the natural guardian in terms the mother is not, and in the exposure of a wife to unilateral divorce in the uncodified systems. The Constitution promises equality before the law and forbids discrimination on the ground of sex, and it expressly preserves the power of the state to legislate for social welfare and reform, so the constitutional order itself contemplates the reform of religiously grounded law; the Constituent Assembly members who defended Article 44, Munshi on the ground that a common code would consolidate a fragmented national life and Alladi Krishnaswami Ayyar on the ground that it would promote amity, made the argument in that form at the founding. The modern carriers of the position include the Bharatiya Muslim Mahila Andolan, an organisation of Muslim women that campaigned against instant triple talaq and for a codified Muslim family law drawn from the Quran read with constitutional values, and scholars such as Tahir Mahmood, who argued across a long career that the personal laws should be reformed toward common and gender-just standards and that the state has been too timid in using the powers it plainly has. The Law Commission’s twenty-second incarnation renewed the official inquiry in 2023 by inviting public views on a uniform civil code afresh. The reform position’s strongest single exhibit is the asymmetry of codification itself: the community whose law was reformed comprehensively is the community whose women litigate from a code, while women of other communities litigate from texts and precedent administered through a doctrine that may bar constitutional challenge altogether.

The preservation position begins from a different article of the same Constitution. Religious freedom, its proponents say, is not exhausted by worship; Article 26 protects a denomination’s right to manage its own affairs in matters of religion, Article 29 protects a community’s right to conserve its culture, and for many believers the law of marriage and inheritance is not a policy preference but an obligation of faith, a position the All India Muslim Personal Law Board, constituted in 1973 to defend the Shariat’s application, has maintained institutionally for five decades: that Muslim personal law rests on divine command and is not open to legislative reconstruction. The members who opposed the uniform code clause in the Constituent Assembly, Mohammad Ismail Sahib and his colleagues, made the consent argument in its original form: a code imposed on a minority by a majority legislature takes from that minority, by number, what the Constitution promised it in right. The position draws strength from two observations about the record. The codified Hindu law, produced by the majority community’s own Parliament, nonetheless retains provisions that are not uniform and not equal, the guardianship hierarchy among them, which suggests that codification is not by itself the equality it advertises. And the scholar Flavia Agnes, no defender of patriarchal rules, has argued that uniformity and equality are different projects, that a single code drafted in a majoritarian climate may generalise the majority’s customs rather than the Constitution’s values, and that the harder, less dramatic work of reforming each law toward gender justice protects minorities and women together. The twenty-first Law Commission’s consultation paper on the reform of family law, issued on 31 August 2018, gave that view an institutional form, concluding that a uniform civil code was neither necessary nor desirable at that stage and recommending instead the reform of discriminatory provisions within each personal law. The preservation position’s strongest single exhibit is the Goan and Uttarakhand evidence read in reverse: codes that call themselves uniform exclude, exempt and accommodate, so the uniformity being sold is never the uniformity delivered.

A third strand runs beneath the two positions and is claimed by reformers in both camps: reform from within the tradition. Its method is to argue from a system’s own sources that the rule under attack is not the system’s best reading of itself. The Bharatiya Muslim Mahila Andolan’s campaign against instant triple talaq was framed in those terms, as a recovery of the Quran’s staged and arbitrated model of divorce against a later juristic practice, and the Supreme Court’s own reasoning in setting the practice aside included opinions that tested it against the Quran and found it contrary to the text’s injunctions. The Hindu code’s defenders in the 1950s made the same form of argument in reverse, presenting codification as the recovery of a dynamic shastric tradition against its frozen colonial statement. Critics of the third strand observe that it concedes the premise that religious warrant is the test of a rule’s legitimacy, which the constitutional order, with its reform power and its equality guarantee, does not concede. Its defenders answer that a reform a community recognises as its own outlasts a reform imposed on it, and that the durability of a rule change, not the purity of its pedigree, is the measure that matters to the women who must live under it. The strand is recorded here because any honest map of the debate shows three routes in use, legislation from outside, adjudication at the margins, and reinterpretation from within, and because the settlements that have lasted in this field, the code of the 1950s among them, have typically travelled on more than one route at once.

A variant of the reform position that surfaces in every consultation deserves separate statement, because it is frequently mistaken for the preservation position by both camps. It proposes uniformity of rights rather than uniformity of rules: let each community keep its law of marriage and succession in form, the argument runs, but let a floor of entitlements, on age of marriage, consent, maintenance, shares of daughters and widows, and access to divorce, be enacted across all systems so that the substance of citizenship is equal while the forms remain plural. The women’s organisations that pressed versions of this proposal in the decades after the Hindu code argued that the historical demand had always been for gender justice and that a single code was one instrument among others, not the object itself. The twenty-first Law Commission’s family law paper moved in a cognate direction, recommending the amendment of discriminatory provisions across the personal laws rather than a single code. The preservation camp answers that a legislated floor is a code by instalments, achieving by accumulation what its proponents disclaim attempting at once, and that the consent objection applies to each instalment. The reform camp answers that the floor concedes on substance the very majoritarian drafting it professes to fear, since a legislature writing minimum rights for other communities’ laws is exercising the same power a code would use, with less honesty about it. The exchange is recorded here because it locates the true fault line of the modern debate, which runs not between unity and plurality but between two accounts of what equality requires of family law: sameness of rule, or equivalence of protection.

Federalism supplies each camp with one of its favourite arguments, and the symmetry is instructive. The preservation camp argues that the Constitution’s own distribution of the subject, concurrent rather than central, is a considered endorsement of plurality in family law: the framers who declined to place personal law in the Union List cannot be supposed to have intended its compulsory national unification, and the state-level variation the entry produces, Goa’s code, Kerala’s abolition of the joint family, the scheduled protections for tribal custom, is the federal structure working as designed rather than a defect awaiting repair. The reform camp answers from the same text that concurrence is a grant of power to both levels precisely so that reform need not wait for a national consensus that may never form: a state may move first, as Uttarakhand has, and the republic’s family law has repeatedly advanced by state experiment later generalised, the daughters’ coparcenary amendments being the clearest case, in which four states wrote the rule before Parliament adopted it for the country. Both arguments are faithful readings of Entry 5, and their collision is the deepest form of the debate this article maps: whether the concurrent placement is a settlement to be honoured or an instrument to be used. The entry itself, characteristically, supports both descriptions, because it is both.

Between the positions lie the facts neither side disputes. The competence to legislate is concurrent. The aspiration to a code is recorded and unenforceable. Codified law can be tested and uncodified law, on the governing doctrine, largely cannot, and that doctrine stands doubted but unreversed. The full debate, the parliamentary history of the code proposal and the merits of the competing drafts, is conducted in the article that owns the uniform civil code debate, and this guide takes no side in it; its work is done if the reader can no longer mistake the map for either side’s pamphlet.

The comparative glance outward, which this guide permits itself once, sharpens the Indian choices by contrast. Pakistan codified much of Muslim family law by the Muslim Family Laws Ordinance of 1961, regulating the registration of marriages, the procedure of talaq through notice and a reconciliation window, and the succession rights of orphaned grandchildren, and the ordinance survived the constitutional changes of that country to remain the region’s standing example of codification within a single tradition rather than across traditions. Sri Lanka maintains a plural system of its own, with the general law beside Kandyan law, the Tesawalamai of the Tamils of the north, and Muslim law administered through specialised Quazi courts. The Indian arrangement differs from both in the feature this article has made central: the plural systems are not a survival the Constitution tolerates at its edges but a field the Constitution itself allocates, entry by entry, between two levels of legislature, and insulates, in the tribal schedules, by name. Comparisons that treat the Indian system as an unmodernised residue therefore miss its character. It is a designed pluralism, designed in layers by administrators, judges and constitution-makers who each knew the alternative and chose, for reasons they recorded, to keep the assignment of family law by community and to argue about its contents instead.

How to navigate the field

A reader facing an actual family law question works through a fixed sequence, and the sequence is the article’s payload in its most usable form. First, classify: determine the personal law of each party by birth, faith and domicile, remembering the wide statutory definition of the Hindu code and the exclusions from it, because classification selects the system. Second, locate the subject: marriage, divorce, maintenance, adoption, guardianship and succession each have their own sources within the system, and a subject codified for one community may be uncodified for another. Third, check the overlays: the general statutes on child marriage, dowry, domestic violence, maintenance under the criminal procedure code and adoption under the juvenile justice legislation apply across systems and frequently supply the operative remedy. Fourth, check the territory: Goa runs on its own code, scheduled and tribal areas carry constitutional protections for custom, and a state amendment may have altered the central statute’s operation within the state. Fifth, where the question is contested, identify the form of the rule attacked, because the codified or uncodified character of the rule decides the forum in which it can be fought. The general position described in this guide is legal information, not advice on an individual matter, and questions of classification, limitation and forum should be taken to a practitioner with the documents in hand, since in this field the answer turns on facts of birth, rite and domicile that no general account can weigh. An aspirant preparing the subject for examination will find that the examinable core is exactly the architecture set out here, Entry 5, Article 44, the religion clauses and the 1952 doctrine, and can work through previous-year questions on the personal law cluster through the ReportMedic presentation viewer to test the distinctions this guide has drawn.

The sequence can be watched working on a single illustrative set of facts, stated abstractly so that the method and not any person’s case is the subject. Take two spouses married by Hindu rites, later living in Goa, where one dies leaving ancestral property in a second state and a self-acquired house in Goa. Classification places both parties within the Hindu code. Location of the subjects splits the estate work: the marriage’s validity is a Hindu Marriage Act question, tested by the rites and the custom of the community, while the succession work divides, because the parties’ domicile in Goa engages the Goan code for the property it reaches, as the Coutinho decision illustrates, and the Hindu Succession Act for the ancestral property in the state where that Act runs. The overlays then do their quiet work: any minor child’s guardianship engages the welfare principle under the general statute of 1890, any maintenance claim by a dependent parent engages the summary remedy, and the whole estate plan, if the deceased had made a will, is tested against the testamentary rules of whichever system the classification and the domicile select. No single statute in the field answers more than part of the file, and the part each answers is determined before any question of substance is opened, which is the sense in which the architecture, rather than any provision, is the law a practitioner in this field principally knows.

For the reader who intends to work in the field, the reading order that builds the architecture fastest is the order of this guide itself. Begin with the constitutional text: Entry 5, Articles 25, 26, 29, 13 and 44, and the two decisions that organise them, Narasu Appa Mali for the immunity and Minerva Mills for the relation between the rights and the aspiration. Then read the shortest consequential statute in the field, the Application Act of 1937, entire, because its six operative sections teach more about how the system assigns questions than volumes of commentary. Then read one code statute against its uncodified counterpart on a single subject, the divorce provisions of the Hindu Marriage Act beside the dissolution scheme of Muslim law, ground by ground, until the difference between a judicial and an extra-judicial architecture is felt rather than recited. The table in this guide, used as a checklist against the bare Acts, will expose any error in the comparison within an hour.

The verdict the map supports is the namable claim with which this article began. Personal law in India is concurrent, not central: the Constitution placed the whole field in the list that two levels of legislature share, and the seventy-year argument about its reform, conducted as a national argument about a single future code, has systematically understated the power that state legislatures have always held and have repeatedly used, from abolishing the joint family in Kerala to amending succession state by state to enacting a complete code in Uttarakhand. A reader who holds that one fact, together with the doctrine that the form of a rule decides its testability, holds the two keys that open nearly every door in the field. The statutes will change; amendments are pending in the ordinary way of legislation, and the doctrine of 1952 awaits the considered ruling that will confirm or displace it. When that ruling comes, it will have to choose between the text of Article 13, which counts custom or usage having the force of law as law, and a practice of seven decades built on the narrower reading; and whichever way it chooses, the codified law stands unaffected on one side of the line and the legislatures’ concurrent power stands unaffected on the other. The map, in other words, survives its own largest uncertainty. The architecture, an assigned law, a concurrent competence, a recorded aspiration and an unsettled immunity, is the durable object, and it is the architecture that the next cluster of articles, on the Hindu code, the secular marriage statute and the Muslim women statutes, will each be found working within.

Frequently Asked Questions

Q: What does personal law govern in India?

Personal law governs the family-centred subjects of private law: the validity and dissolution of marriage, judicial separation and restitution of conjugal rights, maintenance during and after marriage, the legitimacy and guardianship of children, adoption, wills, intestate succession, and the holding and partition of joint family property. It governs those subjects community by community, so the rule that decides a question depends on the religious community of the parties. Matters outside the family core, crime, contract, property transfer, taxation and evidence, are governed by general law that applies to everyone in the territory alike. The constitutional source of the field is Entry 5 of the Concurrent List, whose closing words cover all matters in respect of which parties in judicial proceedings were subject to their personal law when the Constitution commenced.

Q: Which communities are governed by which personal law?

Hindus, a statutory class that includes Buddhists, Jains and Sikhs, are governed by the four codified statutes of 1955 and 1956 on marriage, succession, guardianship, adoption and maintenance. Muslims are governed mainly by uncodified Muslim law, applied through the Application Act of 1937, with particular statutes on wives’ dissolution suits, divorced women’s maintenance and instant talaq. Christians take marriage from the Act of 1872, divorce from the Act of 1869 as amended in 2001, and succession from the Indian Succession Act of 1925. Parsis take marriage and divorce from the Act of 1936 and succession from the Succession Act. Jews have no statute and rely on custom and the Succession Act. Anyone may instead use the secular route of the Special Marriage Act of 1954.

Q: Is personal law a state or a central subject?

It is both. Marriage and divorce, infants and minors, adoption, wills, intestacy and succession, joint family and partition, and all matters historically subject to personal law form Entry 5 of the Concurrent List in the Seventh Schedule. Parliament and every state legislature are therefore competent to legislate on personal law. Where a state law conflicts with a parliamentary law on the same entry, Article 254 resolves the conflict: the parliamentary law generally prevails, but a state law reserved for the President’s consideration and assented to prevails within that state until Parliament legislates over it. States have used the power repeatedly, amending succession law for their territories, abolishing the joint family in Kerala, and, in Uttarakhand, enacting a complete civil code for the state’s residents.

Q: Can personal law be tested against fundamental rights?

A codified provision can: a statute is law for the purposes of Article 13 and may be struck down for inconsistency with fundamental rights, as provisions of family statutes have been. An uncodified rule stands differently. In Narasu Appa Mali in 1952 the Bombay High Court held that uncodified personal law is not law in force within the meaning of Article 13 and so cannot be voided under it, however unequal its operation. Judges of the Supreme Court have since doubted that doctrine, Justice Nariman in the triple talaq case of 2017 and Justice Chandrachud in the temple entry case of 2018, but no binding decision has overruled it. The honest summary is that the immunity of uncodified personal law is doubted and unsettled, not abolished.

Q: Which family law statutes are secular rather than religious?

The secular statutes are those that apply irrespective of the parties’ religion. The Special Marriage Act of 1954 provides a civil form of marriage and divorce open to any two persons. The Guardians and Wards Act of 1890 governs court-appointed guardianship for any minor. The Indian Succession Act of 1925 governs succession for Christians, Parsis, Jews and couples married under the Special Marriage Act. The adoption machinery of the juvenile justice legislation is open to adopters of every faith. Alongside these stand the protective overlays that bind all communities: the prohibition of child marriage, the Dowry Prohibition Act of 1961, the domestic violence statute of 2005, and the maintenance provisions of the criminal procedure codes, which the courts have always treated as religion-neutral.

Q: Does Goa have a different family law system?

Yes. Goa continues under the Portuguese Civil Code of 1867, extended to the territory in 1869 and preserved after 1961 by Section 5(1) of the Goa, Daman and Diu (Administration) Act of 1962, which kept in force all laws operating there until a competent legislature amended or repealed them. One code therefore governs marriage, divorce and much of succession for all Goans regardless of religion, with compulsory civil registration of marriage, a default regime of communion of assets between spouses, and a compulsory share reserved for children in a parent’s estate. The system is common rather than perfectly uniform: Catholic church marriages carry civil effect, couples may vary the property regime by antenuptial contract, and succession has been substantially recast by a Goan statute of 2012.

Q: Can a person choose which law governs their marriage?

Yes, within limits the statutes define. Any two persons, whatever their religions, may marry under the Special Marriage Act of 1954 before a marriage officer, and their marriage, divorce and succession are then governed by that Act and the Indian Succession Act, with a statutory exception preserving the Hindu Succession Act where both parties belong to the Hindu code classes. A couple may alternatively marry by the rites of one party’s religion, which brings that party’s personal law into operation and may require the other party’s conversion where the rite demands a shared faith. What a person cannot do is select a personal law at will while marrying by religious rite, or change the governing law of an existing marriage by converting, since conversion does not dissolve a subsisting marriage.

Q: How is tribal customary law treated in family matters?

Tribal customary law receives express constitutional protection beyond the ordinary recognition of custom. In the scheduled areas under the Fifth Schedule, the Governor may direct that Acts of Parliament or of the state legislature shall not apply, or shall apply with modifications, and may make regulations on matters including land transfer. In the autonomous districts under the Sixth Schedule, district councils may themselves make laws on inheritance, marriage, divorce and social customs. Articles 371A and 371G shield the customary law of Nagaland and Mizoram from parliamentary legislation unless the state assembly resolves otherwise. The codifying statutes respect the same boundary: the Hindu Marriage Act does not apply to members of Scheduled Tribes unless the central government directs otherwise by notification, and the Uttarakhand civil code excluded Scheduled Tribes from its scope.

Q: What is Entry 5 of the Concurrent List?

Entry 5 of the Concurrent List, List III of the Seventh Schedule, is the constitutional entry that assigns the personal law subjects to the shared competence of Parliament and the state legislatures. Its text covers marriage and divorce; infants and minors; adoption; wills, intestacy and succession; joint family and partition; and then adds a closing sweep, all matters in respect of which parties in judicial proceedings were immediately before the commencement of the Constitution subject to their personal law. The closing words matter because they tie the entry to the historical personal law jurisdiction rather than to a closed list, capturing subjects the named heads might miss. Every statute discussed in this guide, central and state alike, traces its legislative authority to this entry or to its corresponding place in the scheme of distribution.

Q: What did the Bombay High Court decide in Narasu Appa Mali?

In State of Bombay v. Narasu Appa Mali, decided in 1952 and reported at AIR 1952 Bom 84, a bench of Chief Justice Chagla and Justice Gajendragadkar upheld the Bombay Prevention of Hindu Bigamous Marriages Act of 1946 as a legitimate measure of social reform against a challenge that it discriminated by restraining Hindus alone. On the wider question, the court held that personal law is not included in the expression laws in force in Article 13(1) of the Constitution, so an uncodified rule of personal law cannot be struck down for inconsistency with fundamental rights. The judges differed on whether custom or usage stood inside the definition of law in Article 13, the Chief Justice inclining one way and Justice Gajendragadkar the other. The decision has been doubted by Supreme Court judges since, but never overruled.

Q: What is the difference between codified and uncodified personal law?

Codified personal law is personal law enacted by a legislature: the Hindu code statutes of 1955 and 1956, the Christian marriage and divorce Acts, the Parsi Act of 1936 and the Special Marriage Act of 1954. It can be amended by ordinary legislation and challenged in court under Article 13. Uncodified personal law is the law a court administers without an enacting statute, drawn from classical texts, commentaries, custom and precedent: most of Muslim personal law in India, including marriage formation, divorce by the husband’s modes other than the voided instant form, and intestate succession. The difference is not antiquarian. It decides who can change the rule, a legislature or only the slow movement of precedent, and whether the rule can be tested against fundamental rights at all, which on the 1952 doctrine it cannot.

Q: Which law governs communities that have no personal law statute of their own?

Communities without a statute are governed by a combination of their own custom, as recognised and applied by the courts, and the general statutes that do not exclude them. The Jewish community is the standing example: marriages are contracted by religious rite and recognised, matrimonial relief is fashioned by courts from the community’s law and general principles, and succession falls under the Indian Succession Act of 1925, whose intestacy provisions do not exclude Jews. Small communities and new religious movements face the same position until legislation or precedent settles their status, and classification disputes are decided as questions of fact and law by the courts. A member of such a community who wants a fully statutory framework can marry under the Special Marriage Act of 1954 and adopt through the secular adoption machinery.

Q: How does the Indian Succession Act fit into the personal law system?

The Indian Succession Act of 1925, Act 39 of 1925, is the consolidating succession statute, and its place in the system is deliberately partial. Its intestacy provisions govern Christians, Parsis, for whom it contains a special set of rules, Jews, and persons married under the Special Marriage Act, while standing aside for Hindus, Muslims, Buddhists, Sikhs and Jains on intestacy. Its testamentary provisions reach further, governing wills for most communities, but they do not govern Muslim wills, which remain subject to the uncodified law and its restriction on bequeathing more than a third of the estate without the heirs’ consent. The Act is therefore both a personal law, for the communities it covers, and the secular default into which the elective route leads, and courts have used it to displace older community regimes, as the Kerala Christians learned in Mary Roy in 1986.

Q: What role does custom play in personal law?

Custom is a source of law inside the personal law system, not merely evidence about it. A custom that is ancient, certain, continuously observed and not unreasonable or opposed to public policy can displace the textual rule of the system it belongs to, and Article 13(3)(a) of the Constitution counts custom or usage having the force of law within the definition of law. The codifying statutes regulate custom’s place rather than abolishing it: the Hindu Marriage Act saves customary rites for the validity of a marriage and customary exceptions to its prohibited degrees, while the Muslim Application Act of 1937 moved in the opposite direction, displacing custom in favour of the Shariat across a list of subjects. Tribal customary law stands highest in the hierarchy of protection, with the Fifth and Sixth Schedules and Articles 371A and 371G insulating it from general legislation.

Q: Have Indian states ever legislated on personal law themselves?

Repeatedly, because Entry 5 makes the field concurrent. Kerala abolished the joint Hindu family system by a state statute of 1975, ending a form of property holding that continued elsewhere under the central Act. Andhra Pradesh, Tamil Nadu, Karnataka and Maharashtra each amended the Hindu Succession Act for their own territories to make daughters coparceners in joint family property, years before Parliament extended the same right nationally in 2005. Goa’s distinct system survives by state-level choice under the continuance provision of 1962, and its succession law was recast by a Goan Act of 2012. Uttarakhand carried state competence furthest, enacting a uniform civil code of its own in 2024, assented to by the President and brought into force on 27 January 2025 for the state’s residents, Scheduled Tribes excepted.

Q: Has the Supreme Court struck down a personal law practice?

The clearest instance travelled through a statute. In Shayara Bano in 2017 a five-judge bench set aside instant triple talaq by three votes to two; the leading opinion reasoned that the practice was regulated by the Application Act of 1937, which made it law testable under Article 13, and held it manifestly arbitrary under Article 14. Parliament then declared the practice void and penal by the Act of 2019. Codified provisions have also fallen: the Supreme Court struck down Section 118 of the Indian Succession Act in John Vallamattom in 2003 as discriminating against Christians in testamentary gifts for religious and charitable purposes. What the Court has never done is strike down a rule of purely uncodified personal law standing on its own, which is the space the 1952 doctrine reserves from review.

Q: What does Article 25 of the Constitution protect, and what does it allow the state to do?

Article 25 guarantees freedom of conscience and the right freely to profess, practise and propagate religion, subject to public order, morality and health and to the other fundamental rights. The same article authorises the state to regulate secular activity associated with religious practice, and provides expressly that nothing in it prevents the state from making any law providing for social welfare and reform or for throwing open Hindu religious institutions of a public character to all classes and sections of Hindus, a term the article’s Explanation extends to Sikhs, Jains and Buddhists for that clause. Article 26 adds the right of a religious denomination to manage its own affairs in matters of religion. The architecture is deliberate: practice is protected, denominational management is protected, and the legislative power to reform in the name of social welfare is preserved against both.

Q: Does a person lose property rights by converting to another religion?

No, and the protection is older than the Constitution. The Caste Disabilities Removal Act of 1850, Act 21 of 1850, provides that a person who renounces their religion, or is excluded from its communion or deprived of caste, shall not for that reason lose property or inheritance rights that would otherwise have been enjoyed. The Act was aimed at the classical rule under which a convert, particularly a convert to Christianity, forfeited patrimony. Conversion does change the personal law that governs the convert’s future transactions, and succession to the convert’s own estate may follow the adopted religion’s law, producing results that surprise families, such as a convert’s descendants taking under a different system from their ancestors. But the act of conversion itself strips the convert of nothing already held, and the courts have maintained that distinction.

Q: What are Anglo-Hindu law and Anglo-Muhammadan law?

They are the names given to the bodies of personal law as administered by the British Indian courts, and the names record their hybrid origin. From the judicial plan of 1772, which directed courts to apply the law of the Koran to Muhammadans and the law of the Shaster to Hindus in inheritance, marriage, caste and religious usages, the courts built a system from translations of selected texts, the opinions of court pandits and maulavis until those offices were abolished in 1864, and an accumulating body of precedent in the English manner. The result was Hindu and Muslim law systematised, and in places reshaped, by judicial decision: rules drawn from one school or text could harden into the law for a whole community, and the diversity of lived practice narrowed to what the reports contained. The republic inherited those bodies of law as its starting point in 1950.

Q: Which personal law disputes are heard by family courts?

The Family Courts Act of 1984, Act 66 of 1984, established family courts to hear the disputes the personal laws generate: suits for nullity, restitution of conjugal rights, judicial separation and divorce, declarations about the validity of a marriage or the matrimonial status of a person, disputes over the property of spouses, injunctions arising from a marital relationship, declarations of legitimacy, guardianship and custody of minors, and claims to maintenance. The Act directs the court to attempt settlement first, permits a simplified procedure with relaxed rules of evidence, and provides for the assistance of counsellors and welfare experts. Where family courts have been established, the personal law causes of all communities within their area go to them, so the forum is common even though the substantive law applied remains the parties’ own personal law.
