Sapinda and Prohibited Relationship: Who You Cannot Marry Under Hindu Law

The Question No One Wants To Ask Out Loud

The wedding date is fixed. The cards are at the printer. And then someone older in the family — a chacha, a maami, a buzurg from the village — calls you aside and says it gently. Beta, are these two even allowed to marry? It might be that the boy is the girl's mother's brother's son. It might be that the bride was once the wife of the groom's elder brother who passed away. It might just be that both families share the same gotra and one cousin is murmuring that this could be a problem.

You smile and say it is fine. But that night you cannot sleep. Because if the older relative is right and the marriage falls inside what Hindu law calls a "sapinda" or "prohibited" relationship, the wedding is not just culturally awkward — it is legally void from day one. No maintenance, no inheritance rights, your kids may need extra protection, and a quiet criminal penalty under Section 18(b) of the Hindu Marriage Act, 1955 is sitting on top of it.

This guide is the answer to that 11 PM question. It walks through exactly which relationships Hindu law prohibits, how to count yourself in or out of the prohibition, the narrow custom exception that sometimes saves a family marriage, and what actually happens if a sapinda or prohibited-degree marriage gets solemnised anyway.

The Three-Question Test the Hindu Marriage Act Uses

Section 5 of the Hindu Marriage Act, 1955 (HMA) lists the conditions for a valid Hindu marriage. Two of those conditions — Section 5(iv) and Section 5(v) — are about who you can marry. They ask, in plain English, three questions:

1. Are you within "prohibited degrees" of each other? (Section 5(iv) HMA, defined by Section 3(g) HMA)
2. Are you "sapindas" of each other? (Section 5(v) HMA, defined by Section 3(f) HMA)
3. If yes to either of the above — does a custom governing both of you specifically permit such a marriage?

If you breach Section 5(iv) or 5(v) and no saving custom applies, the marriage is void ab initio under Section 11 HMA — as the Bombay High Court put it in Mangala Bhivaji Lad v. Dhondiba Rambhau Aber, the marriage simply does not come into existence in the eyes of the law.

What "Prohibited Degrees" Actually Means — Section 5(iv) HMA

Section 3(g) HMA defines "degrees of prohibited relationship". The list is long but it falls into four neat buckets:

1. Lineal ascendants and descendants. Father, mother, grandfather, grandmother, son, daughter, grandson, granddaughter — straight up and straight down the family tree.
2. Spouses of lineal ascendants and descendants. Your father's wife (stepmother), your mother's husband (stepfather), the wife of your son or grandson, the husband of your daughter or granddaughter — and the same one degree further out.
3. Wives of certain brothers. Your brother's wife (bhabhi), your father's brother's wife (chachi/tai), your mother's brother's wife (mami), your grandfather's brother's wife and your grandmother's brother's wife — both on the paternal and maternal side.
4. Closely-blood cousins and aunt-nephew / uncle-niece. Brother and sister, uncle and niece (chacha-bhatiji, mama-bhanji), aunt and nephew (bua-bhatija, mausi-bhanja), and the children of two brothers, two sisters, or a brother and a sister.

The Act explicitly says that "relationship" for this purpose includes half-blood, uterine blood and even illegitimate relationships, as well as relationships by adoption — there is no escape route through "but only my half-brother's daughter" or "but he is not my legitimate son".

Two consequences flow once you fall inside this net.

One — the marriage is void and the doctrine of factum valet cannot save it. The Calcutta authority in Bijan v. Ranjit Lal is the classic statement: a prohibited-degree marriage is void absolutely, and the rule that "a fact accomplished cannot be undone" simply does not cure this defect. The marriage is treated as never having happened.

Two — the courts have actually applied this rule to real, common Indian family situations. In Pamwati Gupta v. State of Uttar Pradesh, a Hindu widow who married her deceased husband's brother saw her marriage held void. In D. Meenakshi Sundaram Pillai v. P. Nemmalwar, a man who married his sister's daughter (his bhanji) had the marriage struck down as void. Both fall squarely inside the Section 3(g) categories.

But not every distant family link puts you inside the prohibition. Bayabai v. Mukund is an instructive example: a man married his paternal grandmother's brother's daughter's son's child, and the Bombay High Court held that this relationship was outside the prohibited-degree net. The web is real but it is also bounded — read the four buckets above carefully before you panic.

What "Sapinda" Actually Means — Section 5(v) HMA

Section 3(f) HMA defines sapinda relationship using a generation-counting rule. The rule has three parts:

1. Sapinda relationship extends five generations on the father's side (in the line of ascent through the father).
2. It extends three generations on the mother's side (in the line of ascent through the mother).
3. The line is traced upwards from the person concerned, counting that person as the first generation.

Two persons are "sapindas" of each other if one is a lineal ascendant of the other within these limits, or if both are sapindas to a common ancestor within these limits. The Punjab & Haryana High Court restated this in Prabhjot Singh v. Prabhjit Kaur in the context of a Section 11 HMA challenge.

The history matters because it explains why the rule looks the way it does. Under classical Hindu law, sapinda relationship extended seven degrees on the father's side and five on the mother's. The 1955 Act narrowed this to 5/3, and as the Privy Council had earlier explained in Buddhu Singh v. Laltu Singh, the Mitakshara theory of sapinda is grounded in "particles of one body" — that is, community of blood from a common ancestor — rather than in religious offerings. Modern Section 3(f) HMA simply codifies that biological reading.

The Dayabhaga tradition was slightly different. Under Dayabhaga, a maternal uncle is a sapinda — a point that Aswind Kumar Barik v. Pal Kumari Dassi records explicitly. So a Dayabhaga family in Bengal that wants a mama-bhanji marriage cannot rely on the textual narrowness of Section 3(f) alone; it must lean on a saving custom (which is exactly what the South Indian custom in Venkata v. Subhadra allowed for nephew-niece-of-maternal-uncle marriages, but Bengali custom typically does not).

A Worked Example — Counting Generations the Way the Act Counts Them

Hindu Law commentaries always start the count from the person concerned as generation 1. This trips many people up because in casual conversation we tend to start the count from the parent. Use the Act's method, not the kitchen-table method.

Father's side — five generations:

1. You
2. Your father
3. Your grandfather
4. Your great-grandfather
5. Your great-great-grandfather

Anyone who shares an ancestor up to and including generation 5 with you on the father's side is your sapinda. Generation 6 (great-great-great-grandfather) is no longer sapinda.

Mother's side — three generations:

1. You
2. Your mother
3. Your maternal grandmother

Anyone within those three generations through your mother's line is your sapinda; generation 4 (maternal great-grandmother) is no longer sapinda.

For two collaterals (people on different branches), the test is whether both trace a common ancestor within the relevant 5-generation or 3-generation window. If yes, they are sapindas to each other. If only one is within the window and the other is outside it, they are not sapindas.

Where the line "passes through" a female intervening relative (a mother in the chain of ascent), the proper construction is that the count then drops to three generations rather than five — otherwise the rule produces absurd asymmetric results where the daughter is sapinda but her father is not.

The Custom Carve-Out — And Why It Is Rarely Won

Both Section 5(iv) and Section 5(v) HMA contain identical saving language: "unless the custom or usage governing each of them permits a marriage between the two". This is the carve-out that allows certain South Indian and Punjabi communities to continue their traditional intra-family marriages without breaching the Act.

The most cited example is the Aroras of Punjab. Shakuntala v. Amar recorded a custom permitting marriage between the children of a brother and a sister, or the children of two sisters. Even though such marriages fall squarely inside Section 3(g) HMA's "children of brother and sister" prohibition, they are saved by the proven custom — and the children of those marriages are legitimate.

The catch is the standard of proof. The Karnataka High Court in Thimakku v. Bandhu laid down the four pillars: a custom must be proved with reasonableness, antiquity, continuity and certainty. The Punjab & Haryana High Court reinforced the practical bite in Asha Rani v. Gulshan Kumar, where a customary divorce was claimed but the custom itself was not proved — the marriage was held void. The same evidentiary burden applies here.

Three things you should know before you bank on custom:

• You cannot deduce one custom from another by analogy. If the Aroras of Punjab can do it, that does not mean the Khatris or Banias can do the same. Each community must prove its own custom from scratch.
• Both sides must be governed by the same custom. If the bride's community recognises the marriage but the groom's community does not, the saving clause does not engage.
• Recent practice is not enough. Custom must be ancient and continuous. A handful of post-1955 instances within a community is generally treated as insufficient — the practice must predate the Act and have been observed without break.

If a saving custom genuinely exists in your community, do not just rely on family tradition. Get an opinion from a matrimonial lawyer with affidavits from senior community members and historical evidence — well before the wedding. The cost of doing this in advance is small; the cost of fighting a Section 11 HMA petition years later is enormous.

Use this table as a starting filter, not a final answer. The exact relationship matters, and the existence (or absence) of a community custom is fact-specific.

If You Go Ahead Anyway — Void Marriage and Section 18(b) Penalty

Suppose the marriage happens despite the prohibition. What follows?

The marriage is void ab initio. Section 11 HMA declares it so. As Mangala Bhivaji Lad v. Dhondiba Rambhau Aber records, no decree of court is strictly required to "end" it — there is nothing to end. The wife is not a wife in the eyes of law. She cannot claim maintenance under personal law as a wife, cannot inherit from the man as his widow, and cannot resist his second marriage as a "first wife" because in law she never was.

That said, both Book 1 and Book 2 of the standard Hindu Law commentaries record that the woman of a void marriage can still ask the court for a formal decree of nullity under Section 11 HMA — and once that decree is granted, she becomes entitled to ancillary relief, including permanent alimony under Section 25 HMA. Getting the decree, even though "not strictly required", is what actually unlocks her financial protection.

Section 18(b) HMA adds a criminal penalty. Anyone who procures a marriage for themselves in contravention of Section 5(iv) or Section 5(v) HMA is liable to simple imprisonment which may extend to one month, or a fine which may extend to Rs 1,000, or both. The penalty is small in absolute terms — but it is criminal in nature, and a complaint under Section 18(b) HMA can quietly run alongside a civil Section 11 nullity petition.

Children's rights are protected, but only narrowly. Section 16 HMA, as amended in 1976, deems children of void marriages legitimate — even without any decree of nullity, as Parayan Kandiyal Eravath v. K. Devi made clear. But Section 16(3) HMA limits their inheritance right to the separate property of their parents; they do not become coparceners in the joint family property (Shantaram v. Dagubai). Read together with our companion guide on void vs voidable marriages under Hindu law if you want the full picture.

The criminal angle of bigamy is separate. If a sapinda or prohibited-degree marriage was contracted while one of the parties already had a living spouse, the bigamy provisions in Section 17 HMA and Sections 494/495 IPC also kick in. Sarla Mudgal v. Union of India warns that conversion will not save such a marriage. Bhaurao Shankar Lokhande remains the cautionary case on what counts as a "marriage" for prosecution purposes — proof of valid Hindu ceremonies in the second event is essential.

The Pre-1955 Saving — When the Old Rules No Longer Bite

Section 29(1) HMA contains an important saving for older marriages. A Hindu marriage solemnised before the commencement of the Act — in 1955 — that was otherwise valid will not be deemed invalid only because the parties belonged to the same gotra or pravara, or to different religions, castes or sub-divisions of the same caste.

This saving matters in two situations. First, very old family marriages that the younger generation might want to challenge today on a technical gotra ground — they cannot. Second, court records and probate proceedings involving deceased persons whose marriages happened in the 1940s or earlier — those marriages enjoy this protective shield.

Section 29(1) HMA does not save pre-1955 marriages from challenges based on bigamy, prohibited degrees or sapinda relationship. Those grounds still apply. What it saves is the narrower category of pre-Act gotra/pravara/caste challenges, which were a serious concern under classical Hindu law but were swept away by the Act.

What Should I Actually Do Now?

1. Draw the family tree honestly. Both sides. List names, generations, and the path connecting the bride and groom to any common ancestor. Do not paper over half-blood, illegitimate or adopted links — the Act counts them all.
2. Run the three-question test. Apply Section 3(g) HMA (prohibited degrees) first; then Section 3(f) HMA (sapinda — 5 generations on father's side, 3 on mother's, counting yourself as 1). If the answer is "no" on both, you are clear.
3. If a prohibition seems to bite, ask whether a saving custom applies. The custom must be reasonable, ancient, continuous and certain (Thimakku v. Bandhu) and it must govern both sides. Recent practice or a handful of post-1955 instances will not do.
4. Get the custom proved properly, before the wedding. Affidavits from senior community members, references in older legal commentaries or gazettes, and a written legal opinion. This is far cheaper than a contested Section 11 HMA petition years later.
5. If no saving custom is available, do not "register and hope". The marriage will be void from day one. Postpone the wedding, consult a family-law lawyer and look at honest alternatives.
6. If the marriage has already happened and you have just realised the problem, get advice on a Section 11 HMA petition. The party to the marriage can file. Children's legitimacy is preserved by Section 16 HMA, and ancillary relief such as alimony is available under Section 25 HMA after a nullity decree.
7. Watch the connected risks. Section 18(b) HMA carries a small criminal penalty. If a prior marriage of either spouse was already subsisting, Section 17 HMA + Sections 494/495 IPC add a serious criminal exposure. Plan all three angles together — civil annulment, criminal complaint, maintenance — rather than picking one and hoping the others go away.

A Final Word — Better an Honest Question Than a Lifetime of Doubt

Most families that worry about sapinda or prohibited-degree problems are worrying about distant relationships that, on a careful reading of Section 3(f) and Section 3(g) HMA, fall safely outside the net. A few families — usually those tied to a clearly-recognised community custom — find that their marriage is saved by Section 5(iv) or 5(v)'s carve-out. A small minority discover that the marriage genuinely cannot be solemnised under the Act, and have a clean choice between the Special Marriage Act, 1954 (which has its own list of prohibited degrees but no sapinda concept) or simply not proceeding.

The single mistake to avoid is the third option that some families take — registering the marriage anyway, in the hope that no one will challenge it. That hope often holds for ten or fifteen years, and then breaks at exactly the worst moment: a partition fight, a maintenance suit, an inheritance dispute. By then, the bride is older, the children are older, and the legal cost of unwinding the consequences is enormous.

An honest question to a lawyer today saves a lifetime of doubt. The Hindu Marriage Act, 1955 is firm on the prohibitions but it is also fair: where a custom genuinely exists, the carve-out works; where the relationship is genuinely distant, the marriage is unconditionally valid. Find out which side you are on, and act on the answer.

Frequently Asked Questions

Can first cousins marry under Hindu law?

Generally no. Children of two brothers, two sisters, or a brother and a sister are all within the prohibited degrees defined by Section 3(g) HMA, and a marriage between them is void under Section 11 HMA. The narrow exception is a saving custom that genuinely permits the marriage in your community — for example, the Aroras of Punjab in Shakuntala v. Amar, where children of a brother and a sister, or of two sisters, were allowed to marry. Bijan v. Ranjit Lal makes it clear that the doctrine of factum valet cannot cure this defect — the custom must be actively proved.

How is sapinda relationship counted? Why 5 and 3?

Section 3(f) HMA traces sapinda relationship five generations on the father's side and three on the mother's side. The crucial point is that you count yourself as generation 1, not your parent. So on the father's side, generation 1 is you, generation 2 is your father, generation 3 your grandfather, generation 4 your great-grandfather, generation 5 your great-great-grandfather. Anyone within that line is your sapinda. The 5/3 asymmetry follows the Mitakshara theory of sapinda explained by the Privy Council in Buddhu Singh v. Laltu Singh — community of blood, traced more strictly through the male line.

My uncle wants me to marry his daughter. Is that allowed?

It depends on which uncle. If he is your father's brother (chacha) or your mother's brother (mama), his daughter is your first cousin and the marriage is normally void under Section 3(g) HMA. There is one well-known exception: in many South Indian communities, the maternal uncle's daughter (mama's daughter) can marry her cousin under a long-standing custom — Venkata v. Subhadra is the classical authority. The custom must be proved with reasonableness, antiquity, continuity and certainty as required by Thimakku v. Bandhu, and it must govern both sides of the family.

What is the difference between sapinda and prohibited degrees?

Both make a marriage void, but they target different relationships. Prohibited degrees under Section 5(iv) HMA (defined by Section 3(g) HMA) cover specific named relationships — lineal ascendants and descendants, spouses of those ascendants and descendants, certain brothers' wives, and aunts/uncles/nieces/nephews and first-cousins-through-siblings. Sapinda relationship under Section 5(v) HMA (defined by Section 3(f) HMA) is broader and based on generation count — five through the father, three through the mother. A relationship can fall within sapinda even if it is not specifically named in the prohibited-degrees list.

Same gotra — is it actually a problem after the Hindu Marriage Act?

No. Section 29(1) HMA explicitly saves the validity of marriages between persons of the same gotra or pravara, including marriages performed before the Act came into force in 1955. The classical Hindu law rule that same-gotra marriages were void was swept away. Lata Singh v. State of UP, although focused on inter-caste marriages, reinforces the same liberal direction. So a same-gotra marriage today is fully valid; the only live questions are sapinda relationship and prohibited degrees.

My family belongs to a community where mama-bhanji marriages are common. Is mine safe?

Probably yes, if you can prove the custom. The saving clause in Section 5(v) HMA recognises a custom that permits sapinda marriages, and Venkata v. Subhadra is the classical authority for the South Indian custom of marrying a maternal uncle's daughter. But you must produce real evidence — affidavits from senior community members, historical references, gazettes, decided case law — not just family practice. And the custom must govern both sides, with reasonableness, antiquity, continuity and certainty as Thimakku v. Bandhu requires. A short legal opinion before the wedding is far safer than discovering, ten years later, that your community's practice was not properly recorded.

If our marriage is void for sapinda reasons, what happens to our children?

They are protected. Section 16(1) HMA deems children of a void marriage to be legitimate, even if no decree of nullity is ever passed — Parayan Kandiyal Eravath v. K. Devi delinked Section 16 from Section 11 and made this clear. They cannot be branded illegitimate. The one limit is Section 16(3) HMA — their right to inherit is restricted to the parents' separate property, not the wider Hindu coparcenary. Shantaram v. Dagubai is the leading authority on this restriction.

Can we get married under the Special Marriage Act if Hindu law forbids us?

Possibly not. The Special Marriage Act, 1954 has its own list of prohibited degrees, which broadly mirrors Section 3(g) HMA — first cousins (paternal and maternal, parallel and cross), aunt-nephew, uncle-niece, brother-sister, and the spouses of lineal ascendants and descendants are all blocked under the 1954 Act as well. The Special Marriage Act does not have the sapinda concept, so a relationship that is sapinda but outside the named prohibited-degree list might be marriable under the 1954 Act even if it is void under the HMA. Get specific advice on your relationship before assuming the Special Marriage Act is a way out.

What is the punishment under Section 18(b) HMA?

Simple imprisonment which may extend to one month, or a fine which may extend to Rs 1,000, or both. The penalty applies to anyone who procures a marriage for themselves in contravention of Section 5(iv) HMA (prohibited degrees) or Section 5(v) HMA (sapinda). The amounts are small in absolute terms but the conviction is criminal in nature, and a complaint under Section 18(b) HMA can run alongside a Section 11 HMA civil nullity petition. Where bigamy is also involved, Section 17 HMA read with Sections 494 and 495 of the IPC adds a much heavier criminal exposure on top.

If I have already married my cousin and there is no saving custom, what is my way out?

The cleanest route is a petition for a decree of nullity under Section 11 HMA. Only a party to the marriage can file it. The decree is not strictly necessary because the marriage is already void from day one, but obtaining the decree formally is what actually unlocks ancillary protections — most importantly permanent alimony under Section 25 HMA for the wife, which several High Courts have read to extend to the wife of a void marriage in this narrow sense. Children's legitimacy is already protected by Section 16 HMA. Speak to a family-law lawyer about timing and evidence before filing.
