Why the Question 'Which Law Applies?' Comes First
Indian succession law is not a single, uniform code. Where a person dies without leaving a valid Will, dying 'intestate', the rules that decide who inherits, in what shares, depend on the deceased's personal law, which in India generally tracks religion. Before any family can work out who is entitled to what, it has to answer a threshold question that is sometimes more complicated than it looks: which personal law actually governs this succession? This guide walks through the major regimes and flags where inter-faith marriages and conversions complicate the picture. For a deeper, NRI-specific comparison between the Hindu Succession Act and the Indian Succession Act, see our companion guide linked in the sidebar.
Hindus, Buddhists, Jains and Sikhs: The Hindu Succession Act
The Hindu Succession Act, 1956 governs intestate succession for Hindus, and, by its own definition, extends to Buddhists, Jains and Sikhs as well. For a male dying intestate, Section 8 sets out Class I heirs (widow, sons, daughters, mother, and certain other specified relatives) who inherit simultaneously and in equal shares, ahead of Class II heirs. For a female dying intestate, Section 15 applies a different scheme, generally favouring her own sons and daughters (including a predeceased child's children) and husband first, before property she inherited from her parents or husband reverts, in certain circumstances, along a source-based route back toward that side of the family. Amendments to the Act have also given daughters equal coparcenary rights in ancestral Hindu Undivided Family property, on par with sons.
Muslims: Personal Law, Not a Codified Statute
Succession among Muslims in India is governed by uncodified Muslim personal law, applied by courts through Shariat principles rather than through a single consolidated statute equivalent to the Hindu Succession Act. Sunni succession generally follows the Hanafi school, under which specific, fixed shares are prescribed for certain heirs (Class I 'Sharers', such as the spouse, parents and children, whose entitlements are set at defined fractions of the estate), with the residue distributed among 'Residuaries' according to a defined order of priority. Shia succession follows a somewhat different scheme reflecting Ithna Ashari principles. A distinguishing feature of Muslim succession compared to the Hindu and Indian Succession Act regimes is that even where a valid Will exists, a Muslim testator can generally bequeath no more than one-third of the estate by Will without the consent of the other heirs: intestate-style personal-law shares still govern the remaining two-thirds regardless of the Will.
Christians, Parsis and Most Others: The Indian Succession Act
The Indian Succession Act, 1925 governs intestate succession for Christians, Parsis, and most other communities not covered by a separate personal-law statute (and also governs the making and probate of Wills generally, including for Hindus). For Christians, Part V of the Act allocates the estate among the surviving spouse and children (or, absent children, more remote kindred) according to a defined statutory scheme. Parsis are governed by a separate, more detailed set of provisions within the same Act (Sections 50–56), reflecting distinct Parsi community succession customs that were specifically codified into the Act.
Inter-Faith Marriages and Conversions
Complications arise where a family includes an inter-faith marriage, or where a deceased person converted religions during their lifetime. As a general rule, a person's own personal law, determined by their religion at the time of death, governs the succession to their own estate, regardless of a spouse's or child's different religion. So a Hindu husband's estate is generally governed by the Hindu Succession Act even if his wife is Christian, and vice versa for her own estate. Marriages solemnised under the Special Marriage Act, 1954, however, follow a different rule: succession to the estate of a person whose marriage was registered under the Special Marriage Act is generally governed by the Indian Succession Act's intestate succession provisions (Sections 33 and following), regardless of the deceased's religion, unless the parties were both Hindu, Buddhist, Sikh or Jain: in which case the Hindu Succession Act continues to apply. Families in this situation should identify precisely how the marriage was solemnised and registered before assuming which statute governs.
Getting the Threshold Question Right
Because the applicable law changes so much about who inherits and in what proportion, families dealing with an intestate estate should resolve the threshold question, which personal law actually applies here, before assuming any particular distribution. Where the answer is genuinely unclear (a conversion, an inter-faith Special Marriage Act union, or a mixed-heritage family), it is worth confirming the position formally rather than assuming the majority-religion rule of the extended family automatically applies.
Frequently Asked Questions
Which law decides who inherits if someone dies without a Will in India?
The applicable personal law, which generally tracks the deceased's religion: the Hindu Succession Act, 1956 for Hindus, Buddhists, Jains and Sikhs; uncodified Muslim personal law for Muslims; and the Indian Succession Act, 1925 for Christians, Parsis and most other communities.
Can a Muslim testator leave their entire estate by Will?
Generally no: under Muslim personal law, a testator can ordinarily bequeath no more than one-third of the estate by Will without the consent of the other legal heirs; the remaining two-thirds passes according to the fixed personal-law shares regardless of the Will.
How does a Hindu woman's intestate succession differ from a Hindu man's?
A Hindu woman's intestate estate is governed by Section 15 of the Hindu Succession Act, which generally prioritises her own sons, daughters and husband first, with a separate, source-based rule applying to property she inherited from her parents or husband in certain circumstances: a materially different scheme from Section 8, which governs a Hindu man's estate.
Which law applies if a couple married under the Special Marriage Act?
Succession to the estate of a person whose marriage was registered under the Special Marriage Act, 1954 is generally governed by the Indian Succession Act's intestate provisions, regardless of the deceased's religion: unless both spouses were Hindu, Buddhist, Sikh or Jain, in which case the Hindu Succession Act continues to apply.
Does a person's religion at death or at birth determine which succession law applies?
Religion at the time of death generally governs, so a person who converted religions during their lifetime is typically succeeded to under the personal law of the religion they held when they died, not the religion they were born into.
