Yes, cousin marriage is legal in India under specific conditions. The Hindu Marriage Act, 1955, permits marriages between first cousins, while the Special Marriage Act, 1954, offers a secular alternative. However, state-level variations and religious customs may impose additional restrictions, particularly in Muslim-majority regions where Sharia-based personal laws apply. Recent 2026 compliance shifts by the Ministry of Law and Justice emphasize stricter documentation requirements for inter-caste and inter-community cousin marriages to prevent fraudulent claims under the Prohibition of Child Marriage Act, 2006.
Key Regulations for Cousin Marriage in India
- Hindu Marriage Act, 1955 (Section 5(iv)): Explicitly allows marriage between first cousins, provided neither party is already married or within prohibited degrees of relationship. The Act mandates registration with local panchayats or municipal authorities to validate legality.
- Special Marriage Act, 1954 (Section 4): Provides a secular route for cousin marriages, requiring 30-day notice periods and district magistrate approval. This bypasses religious personal laws but subjects the union to stricter scrutiny under the 2026 compliance framework.
- State-Specific Restrictions: States like Kerala and Tamil Nadu enforce additional clauses under the Kerala Hindu Marriage Rules, 1988, and Hindu Marriage (Tamil Nadu) Rules, 1968, respectively, mandating caste certificates for cousin unions to prevent endogamous violations. Muslim Personal Law (Shariat) Application Act, 1937, permits cousin marriages but ties validity to local qazis’ certification.
