Yes, it is illegal to marry your first cousin in Pennsylvania. State law explicitly prohibits marriages between first cousins, and such marriages are considered void if performed within Pennsylvania.
What Pennsylvania Law Says
Pennsylvania’s marriage statutes are clear:
- A man may not marry his first cousin.
- A woman may not marry her first cousin.
These prohibitions are found in the state’s official code and are enforced by the state’s marriage licensing authorities.
If a marriage between first cousins is performed in Pennsylvania, it is considered void under state law. This means the marriage is not legally recognized, and the couple does not have the legal rights or responsibilities of married spouses in Pennsylvania.
Out-of-State Marriages
Some couples may consider marrying in a state where first cousin marriage is legal and then returning to Pennsylvania.
However, Pennsylvania courts may refuse to recognize such marriages if they are deemed to violate the state’s strong public policy against cousin marriage.
The recognition of out-of-state cousin marriages is not guaranteed and can be challenged in court, especially if issues of inheritance, divorce, or child custody arise.
