Yes, cousin marriage is legal in Denmark under strict conditions. The Danish Marriage Act permits first-cousin unions if both parties are 25+ years old, provide genetic counseling certificates, and demonstrate no familial dependency risks. Local municipalities enforce these rules, with the Agency for Family Law (Familieretsstyrelsen) overseeing compliance.
Key Regulations for Cousin Marriage in Denmark
- Age and Counseling Requirement: Both parties must be at least 25 years old and submit genetic counseling reports from certified Danish health authorities to assess hereditary risks.
- No Dependency Clauses: Marriages are prohibited if one cousin is financially or emotionally dependent on the other, as determined by municipal social services.
- 2026 Compliance Shift: New EU-aligned regulations, effective January 2026, mandate additional psychological evaluations for first-cousin applicants to align with broader Nordic family law harmonization efforts.
