Cousin marriage is a topic that often raises eyebrows, especially in the United States where the laws differ from state to state. While it might be allowed in some places, it’s strictly banned in others.
If you’re in Kentucky and wondering whether marrying your cousin is legal, the answer is clear—and the consequences can be serious. Let’s break down exactly what the law says about cousin marriage in Kentucky.
What Does the Law Say About Marrying Your Cousin in Kentucky?
In Kentucky, it is illegal to marry your first cousin. The law clearly prohibits marriage between close relatives, including:
Parents and children
Siblings
Grandparents and grandchildren
Aunts/uncles and nieces/nephews
First cousins
This rule is found in Kentucky Revised Statute (KRS) 402.010, which states that marriages between closely related individuals are void and not recognized by the state.
Why Is Cousin Marriage Illegal in Kentucky?
The main reasons for banning cousin marriages are:
Health concerns: Children born to closely related parents may have a higher risk of genetic disorders.
Social norms: In many parts of the U.S., marrying a close relative is seen as socially unacceptable.
Legal consistency: The law aims to prevent potential complications related to family inheritance, guardianship, and custody.
Are Any Types of Cousin Marriage Allowed?
Kentucky’s law only bans first cousin marriages. That means:
Second cousins or more distant relatives can legally marry in Kentucky.
Step-cousins or adopted cousins (if not biologically related) may not fall under the same restrictions.
However, if there’s any doubt, it’s best to consult a legal expert before proceeding with a marriage.
What Happens If You Marry Your Cousin Anyway?
If two first cousins get married in Kentucky—either by mistake or knowingly—the marriage is considered void, meaning it’s not legally valid. This can have serious consequences:
The couple won’t be recognized as legally married.
They may face legal penalties, especially if the marriage was entered into knowingly.
Any children from the union may face issues regarding inheritance and custody.
If a cousin marriage was legally done in another state where it’s allowed, Kentucky may still not recognize it, depending on the circumstances.
Can You Marry Your Cousin in Another State and Move to Kentucky?
Some states, like California or New York, allow first cousins to marry. But if a couple legally marries in one of those states and then moves to Kentucky, their marriage might not be recognized.
Kentucky law gives the state the right not to recognize a marriage that goes against its public policy. Since cousin marriage is clearly against Kentucky’s policy, there’s a strong chance it would not be valid in the state.
States That Allow First Cousin Marriage
If you’re considering marrying your cousin and are looking for legal options, here are some U.S. states where first cousin marriage is legal:
California
New York
Florida
New Jersey
Colorado
But always remember: just because it’s legal in one state doesn’t mean it will be recognized everywhere else.
In Kentucky, marrying your first cousin is illegal under state law. The marriage is not recognized, and attempting it could lead to legal trouble. While other states may have different laws, Kentucky strictly prohibits marriage between close blood relatives.
If you’re unsure about your relationship status or family connection, it’s always best to check with a lawyer before making any decisions. Understanding the law helps you avoid complications and make informed choices about your future.
