Yes, cousin marriage is legal in California under specific conditions. The state permits first-cousin unions but prohibits marriages between closer relatives, aligning with California Family Code § 2200. No state license restrictions exist for cousins, though local clerks may require additional documentation.
Key Regulations for Cousin Marriage in California
- Prohibited Degrees of Relationship: California Family Code § 2201 explicitly bans marriages between siblings, half-siblings, parents/children, aunts/uncles, and nieces/nephews. Violations invalidate the union.
- First-Cousin Eligibility: First cousins may marry if both parties are 18+ and not otherwise prohibited by § 2200. No additional permits are required beyond standard marriage licenses.
- Local Clerk Discretion: County registrars (e.g., Los Angeles County Registrar-Recorder) may request proof of relationship (e.g., birth certificates) to verify eligibility, per § 306.1 of the California Code of Regulations.
Compliance Note: While no 2026 statutory changes are pending, the California Department of Public Health monitors marriage license trends for potential regulatory review. Out-of-state residents must comply with California’s laws if marrying within the state.
