Iowa law prohibits marriage between first cousins, classifying such unions as void from the start. More distant relatives like first cousins once removed or second cousins face no such ban.
State Marriage Statutes
Iowa Code Section 595.19 explicitly lists first cousins among prohibited relationships, including parents, siblings, aunts, uncles, nieces, and nephews. These marriages hold no legal validity, denying rights like inheritance or spousal benefits.
The prohibition stems from concerns over genetic risks in offspring, though cultural norms also play a role. No exceptions exist for age, fertility, or counseling, unlike some states.
Allowed Relationships
Second cousins and beyond can marry freely. First cousins once removed—your parent’s first cousin or your first cousin’s child—are permitted since shared DNA drops significantly.
Out-of-state first cousin marriages by Iowa residents remain unrecognized, creating potential complications for couples.
Comparison to Other States
Iowa joins 32 states banning first cousin marriage outright. Neighboring states vary: Kansas and Nebraska allow it, while Minnesota restricts under certain conditions.
| State | First Cousins Allowed? | Key Restriction |
|---|---|---|
| Iowa | No | Void marriages |
| Kansas | Yes | None |
| Nebraska | Yes | Age 50+ or infertile |
| Minnesota | No | Criminalized |
Legal Consequences
Attempting marriage triggers no criminal penalties, but the union is automatically invalid. Courts uphold this in disputes over property or custody.
Bigamy charges could arise if one party is already married elsewhere.
Practical Advice
Verify family trees via records before pursuing marriage licenses—county clerks check IDs and affidavits. Genetic counseling helps for close relations.
Iowa prioritizes public health in kinship rules. For borderline cases, consult an attorney to navigate nuances.
