Is marriage between cousins valid under Hindu law prohibited degrees rules?

Question

My family wants to arrange my marriage with a cousin, but I heard this may be prohibited under Hindu law. Is such a marriage legally valid? I have been reading conflicting things online and I would like to understand what Indian law actually says about this, which Act and Section applies, what the realistic timelines and costs are, and what I should be doing right now to protect my position. If the matter can be resolved without litigation I would prefer that route, but I want to know what my rights are before I agree to anything or sign any document.

Is marriage between cousins valid under Hindu law prohibited degrees rules? is governed in India primarily by Hindu Marriage Act 1955, Section 3, Hindu Marriage Act 1955, Section 5 and Hindu Marriage Act 1955, Section 11. The short answer is set out below, followed by the practical steps most people in this situation need to take. Read it alongside the specific provisions named, because the exact relief available to you turns on the facts you can prove on paper.

Section 5 of the Hindu Marriage Act 1955 requires that neither party be within the 'degrees of prohibited relationship' or be 'sapindas' of each other unless a custom or usage governing each of them permits such a marriage.

Section 3 defines 'degrees of prohibited relationship' and 'sapinda relationship' in detail, generally covering close blood relatives such as first cousins on either side within specified generations.

Many South Indian communities have long-recognised customs permitting cross-cousin or uncle-niece marriages, and courts have upheld such marriages as valid where the custom is proved to be ancient, certain and reasonable.

Section 11 declares a marriage in contravention of Section 5's prohibited relationship clause to be void from the outset, unless it falls within a recognised customary exception applicable to the parties.

Parties relying on custom to validate a cousin marriage should be prepared to prove the existence and continuity of that custom in their community if the marriage is ever challenged in court.

What to do next: 1) Check whether the proposed relationship falls within the 'prohibited relationship' or 'sapinda' definitions under Section 3; 2) If a community custom permits the marriage, gather evidence such as prior instances or community affidavits proving the custom; 3) Consult a family lawyer before solemnising the marriage if there is any doubt about the degree of relationship; 4) Register the marriage after solemnisation to create documentary proof for future reference.

If the other side has already issued a notice, filed a case or set a deadline, treat the matter as time-sensitive — most remedies under Hindu Marriage Act 1955, Section 3 carry limitation periods, and a delay you cannot explain weakens an otherwise strong case.
