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 would rather settle this without going to court if the law allows it, but I need to know my rights before I sign anything. Please tell me what to do first and what document to keep.

Under Indian law, Hindu Marriage Act 1955, Section 3 is the starting point for this family law question. What follows is the position in substance, together with the steps that usually make the difference in practice.

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.

Practical steps: 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 — remedies under Hindu Marriage Act 1955, Section 3 carry limitation periods, and unexplained delay weakens an otherwise strong case.
