In Indiana, it is generally illegal for first cousins to marry. The law specifically prohibits marriage between individuals who are more closely related than second cousins. However, there is a notable exception: first cousins may legally marry if-and only if-both individuals are at least 65 years old.
Why the Age Exception?
This age-based exception is rooted in concerns about potential health risks for children born to closely related parents. Since couples over 65 are less likely to have children, the state allows first cousin marriage at that age.
What About Other Cousins?
- Second cousins and more distant relatives can marry at any age in Indiana.
- First cousins once removed are also permitted to marry under state law.

Key Takeaway
