1. Sources, Scope and Application of Hindu Law

This is the first post in Family Law-I (Hindu Law), Unit I — before we get to Joint Family or Karta, we need to know what "Hindu law" actually is, who it governs, and where its rules come from.

The Problem This Topic Solves

Ask a hundred people "who is a Hindu?" and you will get a hundred different answers — some religious, some cultural, some legal. But when a court has to decide a case on marriage, succession, or adoption, it cannot work with a vague answer. It needs to know exactly which persons a rule applies to, and exactly where that rule comes from — a 3,000-year-old text, a custom followed in one village, or an Act passed by Parliament last century. This post answers both questions: the scope of Hindu law (who it applies to) and its sources (where its rules come from).

What "Hindu Law" Means

"Hindu law" is the body of personal law that governs Hindus — and, by legal extension, Buddhists, Jains, and Sikhs — in matters like marriage, divorce, adoption, guardianship, succession, and joint family property. It is not one single code. It is a layered system: ancient religious and customary material at its base, reshaped and largely codified by Parliament in the 1950s into a handful of modern Acts that most courts now apply directly.

Scope and Application — Who Does Hindu Law Govern?

There is, surprisingly, no single exhaustive statutory definition of the word "Hindu." Instead, Section 2 of the Hindu Marriage Act, 1955 — the provision courts rely on for the application of Hindu law generally — describes who the Act (and by extension, Hindu law) applies to:

1. Any person who is a Hindu by religion in any of its forms or developments, including a Virashaiva, a Lingayat, or a follower of the Brahmo, Prarthana, or Arya Samaj.

2. Any person who is a Buddhist, Jaina, or Sikh by religion. Even though these are separate religions, the law treats them as governed by Hindu law for these purposes.

3. Any other person domiciled in India who is not a Muslim, Christian, Parsi, or Jew by religion — unless it is proved that such a person would not have been governed by Hindu law had this Act not been passed. This is effectively a negative or residuary test: if you don't belong to one of the four excluded religions and you live in India, you are presumed to be governed by Hindu law.

The Explanation to Section 2 clarifies three categories of persons who count as Hindu, Buddhist, Jain, or Sikh "by religion": (a) a child, legitimate or illegitimate, both of whose parents belong to one of these four religions; (b) a child with only one such parent, if raised as a member of that parent's community; and (c) any person who converts or re-converts to one of these religions.

• Section 2 does not define "Hindu" positively for every case — it works largely by exclusion: not Muslim, Christian, Parsi, or Jew, and domiciled in India.
• Buddhists, Jains, and Sikhs are separate religions but are statutorily brought under Hindu law for matters like marriage and succession.
• Section 2(2) excludes members of Scheduled Tribes from the Act unless the Central Government specifically directs otherwise by notification.

• Courts have repeatedly held that a person does not lose their status as a Hindu under this Section merely by holding a separate "minority" status for other constitutional purposes — Jains and Sikhs, for example, remain governed by Hindu law for marriage and divorce even though they are recognised as religious minorities under the National Commission for Minorities Act, 1992.
• A person converting away from Hinduism, Buddhism, Jainism, or Sikhism to another religion generally ceases to be governed by Hindu law, subject to specific statutory provisions on the consequences of such conversion (relevant later, in the context of adoption and maintenance).

Sources of Hindu Law

Hindu law draws on two broad categories of sources — the ancient, religious and customary material that shaped it for centuries, and the modern, State-made law that governs most day-to-day questions today.

1. Shruti Literally "that which is heard." Shruti refers to the four Vedas (Rig, Yajur, Sama, and Atharva), along with the Brahmanas and Upanishads attached to them. Traditionally regarded as of divine origin and the most authoritative source of all, Shruti today is of limited practical use in courts — its content is largely religious and ritualistic rather than a working code of civil rules — but it remains historically foundational.

2. Smriti Literally "that which is remembered." Smritis are texts composed by sages who recollected and systematised the teachings of the Shruti into workable rules of conduct. They fall into two groups: the earlier Dharmasutras (e.g., by Gautama, Baudhayana, Apastamba, and Vasishtha), written in prose, and the later Dharmashastras, written in verse — most importantly the Manusmriti, and the Yajnavalkya Smriti, which became the base text for the most influential commentary in Hindu law, the Mitakshara.

3. Commentaries and Digests (Nibandhas) Written roughly between 700 and 1700 CE, these are detailed explanations and reconciliations of the Smritis by later scholars, often resolving direct contradictions between different Smriti texts. The two most important — the Mitakshara (by Vijnaneshwara, a commentary on the Yajnavalkya Smriti) and the Dayabhaga (by Jimutavahana) — are so influential that they gave rise to the two major Schools of Hindu law, which is the subject of our next post.

4. Custom Long-established practice, followed consistently by a family, caste, community, or locality, which has acquired the force of law. Custom holds a genuinely powerful place in Hindu law — strong enough, in fact, to override the written texts themselves.

Sources of Hindu Law — At a Glance

5. Legislation Since the 1950s, Parliament has codified most of Hindu personal law into statute — principally the Hindu Marriage Act, 1955, the Hindu Succession Act, 1956, the Hindu Minority and Guardianship Act, 1956, and the Hindu Adoptions and Maintenance Act, 1956 (together sometimes called the "Hindu Code Bills"). For any matter these Acts cover, the statute is the first and controlling source — courts turn to the older Shastric or customary sources only where the statute is silent or expressly preserves custom.

6. Judicial Precedent Decisions of the Supreme Court are binding on all courts in India under Article 141 of the Constitution, and High Court decisions bind courts within their jurisdiction. Precedent is essential wherever a codifying Act uses a term or leaves a gap that only the courts have since clarified.

7. Justice, Equity, and Good Conscience Where neither statute, custom, nor binding precedent covers a situation, courts fall back on general principles of fairness and reason. This is a residuary source — used sparingly, but it has genuinely shaped Hindu law in areas the codifying Acts did not fully anticipate.

A Practical Example

Suppose a Hindu couple from a community that traditionally marries through a specific customary ceremony wants to know if their marriage is legally valid. The starting point is the modern source — Section 5 of the Hindu Marriage Act, 1955, which lays down the general conditions for a valid Hindu marriage. But Section 7 of the same Act expressly preserves the older, ancient source: a marriage is valid if solemnised according to the customary rites and ceremonies of either party. So the legislation (modern source) sets the framework, while custom (ancient source) fills in the actual ceremonial content — showing how the two categories of sources work together rather than one simply replacing the other.

Quick Revision Points

• Hindu law applies to Hindus, Buddhists, Jains, and Sikhs by religion, and residually to anyone domiciled in India who is not Muslim, Christian, Parsi, or Jew (Section 2, Hindu Marriage Act, 1955).
• Scheduled Tribes are excluded from the Act unless the Central Government directs otherwise.
• Ancient sources: Shruti (Vedas), Smriti (Dharmasutras and Dharmashastras), Commentaries and Digests (Mitakshara, Dayabhaga), and Custom.
• Modern sources: Legislation, Judicial Precedent, and Justice, Equity and Good Conscience.
• Custom can override the written Shastric text if proved — Collector of Madura v. Moottoo Ramalinga Sathupathy (1868).
• Where a codifying Act like the Hindu Marriage Act applies, it is the primary source; older sources fill gaps or are expressly preserved (e.g., customary marriage rites under Section 7).
