Which States Still Allow Cousins to Marry? A Detailed Look at U.S. Marriage Laws
The question of whether or not cousins can legally marry in the United States is a surprisingly nuanced one. While many people assume it's a blanket prohibition or a widespread allowance, the reality is that marriage laws are determined at the state level. This means that the legality of cousin marriage varies significantly from one state to another. As of today, a substantial number of states still permit first cousins to marry, though a significant minority have restrictions or outright bans.
Understanding the Legal Landscape
The laws surrounding cousin marriage are rooted in a complex history that blends concerns about genetics, social norms, and religious beliefs. Historically, many states enacted laws to prevent consanguineous marriages (marriages between closely related individuals) out of fear of genetic defects in offspring. However, modern scientific understanding of genetics has led many to re-evaluate these laws. It's important to note that "first cousin" refers to individuals who share a common grandparent. This is the most common definition when discussing marriage laws.
States Where First Cousin Marriage is Generally Permitted
As of the most recent available information, there are a significant number of states where first cousins can marry without any special conditions or restrictions. These states recognize such unions as legally valid. Here is a list of states where, in general, first cousins are permitted to marry:
- Alabama

States with Restrictions or Conditions
While the majority of states allow first cousin marriage, a smaller group has put specific limitations in place. These restrictions can range from requiring that the couple be of a certain age, that one or both individuals are infertile, or that they have obtained a doctor's certificate regarding their fertility. In some cases, these laws were enacted before a complete understanding of genetic risks, and the conditions are now considered outdated by some.
Here are the states that have restrictions on first cousin marriage:
- Georgia: While generally allowed, there are specific historical limitations that are rarely enforced in practice but can technically exist. It's often considered permitted.
- Kentucky: Generally allowed, but if the couple has offspring, the children are considered legitimate. This implies a historical concern.
- Maryland: Permitted.
- Missouri: Permitted.
- Nebraska: Permitted.
- Nevada: Permitted.
- New Hampshire: Permitted.
- New Jersey: Permitted.
- New Mexico: Permitted.
- New York: Permitted.
- North Carolina: Permitted.
- North Dakota: Permitted.
- Ohio: Permitted.
- Oklahoma: Permitted.
- Oregon: Permitted.
- Pennsylvania: Permitted.
- Rhode Island: Permitted.
- South Carolina: Permitted.
- South Dakota: Permitted.
- Tennessee: Permitted.
- Texas: Permitted.
- Utah: Permitted.
- Vermont: Permitted.
- Virginia: Permitted.
- Washington: Permitted.
- West Virginia: Permitted.
- Wisconsin: Permitted.
- Wyoming: Permitted.
Please note: The landscape of marriage laws can evolve. It is always advisable to consult with local authorities or legal counsel for the most up-to-date and specific information regarding marriage in a particular state.
States Where First Cousin Marriage is Prohibited
Conversely, a smaller but notable group of states outright prohibits first cousins from marrying. These prohibitions are generally absolute and do not come with exceptions based on age or fertility. The reasons for these bans are often tied to historical concerns about genetic inheritance and social norms.
Here are the states where first cousin marriage is prohibited:
- District of Columbia
- Illinois
- Louisiana
- Michigan
- Mississippi
- Montana
- Ohio
- Oregon
- Washington
It is important to understand that the laws are complex. For example, in some states, while marriage between first cousins is prohibited, the marriage may still be considered valid if it was legally performed in another state where it is permitted. This is due to the Full Faith and Credit Clause of the U.S. Constitution.
Second Cousins and Beyond
When discussing cousin marriage, it's usually first cousins that are the primary focus. Relationships that are more distant, such as second cousins (individuals who share a great-grandparent) or third cousins, are almost universally permitted to marry in all U.S. states. The genetic risks associated with more distant cousin relationships are generally considered negligible.
Why the Variation in Laws?
The reasons behind the differing state laws are multifaceted. Historically, concerns about the increased risk of recessive genetic disorders in offspring of closely related parents were a significant driver for these laws. However, with advances in genetic counseling and a greater understanding of these risks, many states have reviewed and updated their legislation. Social and religious viewpoints have also played a role in shaping these laws over time.
What About Marriage Between More Distant Cousins?
Generally, marriage between second cousins (you share a great-grandparent) or more distant cousins is legal in all U.S. states. The genetic concerns associated with these relationships are considered minimal.
Is It Legal to Marry Your First Cousin in [Specific State]?
To determine the legality of marrying your first cousin in a specific state, you would need to consult the marriage laws of that particular state. The lists provided above offer a general overview, but it's always best to get confirmation from official sources or legal professionals in that jurisdiction.
Are There Any Exceptions to the Rules?
Yes, in some states that have restrictions, there might be exceptions. These can include requirements that one or both individuals are infertile, that they have obtained a doctor's certificate confirming infertility, or that they are of a certain age. However, these exceptions are not universal and depend entirely on the specific state's laws.
Why Did Some States Ban Cousin Marriage in the First Place?
The primary historical reason for banning cousin marriage was the concern about an increased risk of genetic disorders in the children of such unions. This was based on the principle that closely related individuals are more likely to share the same recessive genes that can lead to health problems. Social and religious views also played a part in shaping these early laws.
Does This Apply to Same-Sex Couples?
The laws regarding cousin marriage apply equally to all couples, regardless of sexual orientation. Marriage equality in the United States means that if a particular state permits first cousins to marry, it does so for all couples within that state.
