No, it is not illegal to marry your cousin in California.
California law allows marriage between first cousins. There are no prohibitions against first-cousin marriages in the state, and such unions are fully recognized under California law.
Legal Details
- First Cousins:
Marriage between first cousins is legal in California. The state’s Family Code does not prohibit marriages between first cousins, and there are no special restrictions or requirements beyond those that apply to any other marriage. - Other Relatives:
California law does prohibit marriage between closer blood relatives, such as siblings, parents and children, aunts/uncles with nieces/nephews, and ancestors/descendants of any degree1. - Age Requirement:
Both individuals must be over the age of 18 to marry without special court approval.
Recognition and Interstate Issues
- Recognition in California:
Marriages between first cousins performed in California are legally valid and carry the same rights and responsibilities as any other marriage. - Moving to Other States:
If you marry your first cousin in California and move to a state where cousin marriage is prohibited, your marriage may not be recognized in that new state. Laws on cousin marriage vary significantly across the U.S., so it’s important to check local laws if you plan to relocate.
