In Ohio, marrying a first cousin is effectively illegal due to statutory restrictions. Ohio Revised Code Section 3101.01 states that individuals can only marry if they are not “nearer of kin than second cousins,” which prohibits first cousins from legally marrying each other.
Legal Framework
- Prohibition: Ohio law restricts marriage to those who are second cousins or more distantly related, effectively prohibiting first cousin marriages.
- Consequences: Marriages between first cousins are considered void under Ohio law and will not be recognized by the state, affecting property rights and inheritance.
- No Exceptions: Ohio has a blanket ban on first-cousin marriages with no special exceptions.
- Out-of-State Marriages: Ohio does not recognize first cousin marriages that were legally performed in other states.
Other Considerations
- Second Cousins: Marriages between second cousins and more distant relatives are generally permissible in Ohio.
- Sexual Relations: Sexual relations between first cousins are not classified as incestuous in Ohio.
- Age and Consent: Ohio law states that males may marry at the age of 18 and females at the age of 18, and those who are younger must obtain consent.
- Same-Sex Marriage: Same-sex marriage is legal in Ohio.
It is essential to consult with legal professionals for accurate and up-to-date information, as laws can change.
