In Arizona, marriage between first cousins is generally prohibited, but there are two important exceptions.
General Rule
- First cousin marriage is prohibited and void under Arizona law. This means that, by default, you cannot legally marry your first cousin in the state.
Exceptions: When Can First Cousins Marry?
Arizona law allows first cousins to marry only under specific circumstances:
- If both cousins are at least 65 years old, they may legally marry in Arizona.
- If one or both cousins are under 65, they may marry only with approval from a superior court judge. To get this approval, they must present proof that one of the cousins is unable to reproduce (i.e., is sterile).
If neither of these exceptions applies, a marriage between first cousins in Arizona is void and not legally recognized.
Other Relatives
- Marriages between closer relatives (parent/child, siblings, uncle/niece, aunt/nephew) are always prohibited and void in Arizona.
Out-of-State Marriages
- Arizona may not recognize first cousin marriages performed in other states unless the marriage meets Arizona’s exception criteria.
