In Ohio, marrying your first cousin is illegal. The law explicitly states that individuals who are “nearer of kin than second cousins” are not permitted to marry each other. This means that first cousins-who share a set of grandparents-cannot legally marry in Ohio.
What Does “Nearer of Kin Than Second Cousins” Mean?
- First cousins: Share grandparents. Marriage is not allowed.
- Second cousins: Share great-grandparents. Marriage is allowed.
The law is clear that only couples who are at least second cousins or more distantly related may be legally joined in marriage in Ohio.
Criminal Penalties and Recognition of Out-of-State Marriages
While marrying a first cousin is prohibited, Ohio law does not currently criminalize adult incestuous relationships, meaning that while such a marriage cannot be legally performed or recognized in Ohio, engaging in a relationship with a first cousin is not a criminal offense.
However, marriages between first cousins performed in another state where it is legal are not recognized as valid in Ohio.
