When it comes to dating and marriage laws in the United States, one area that often sparks curiosity — and sometimes controversy — is cousin relationships. While the legality of cousin dating and marriage varies widely by state, the question remains: Is dating your cousin illegal in Wyoming?
In this article, we’ll explore the legal landscape in Wyoming regarding cousin relationships, including what’s allowed, what’s not, and how the state compares to others across the country.
Understanding the Basics: Cousin Relationships Defined
Before diving into the law, it’s important to understand what is meant by “cousin” in this context. Typically, state laws that address cousin relationships are referring to first cousins — that is, people who share a set of grandparents.
There are also second cousins (who share great-grandparents), and more distant relatives such as third or fourth cousins. These distinctions are important because most laws that regulate or prohibit relationships focus primarily on first cousins.
What Wyoming Law Says About Cousin Dating
As of 2025, Wyoming does not have any laws that prohibit dating between first cousins. Dating, in and of itself, is a social relationship and is generally not governed by criminal statutes — unless other legal concerns, such as age of consent or coercion, are involved.
So, to answer the question directly:
Yes, it is legal to date your cousin in Wyoming.
There are no criminal or civil laws in the state that prevent two consenting adults, even if they are first cousins, from engaging in a romantic relationship.
Can First Cousins Get Married in Wyoming?
While cousin dating is legal, marriage laws are often more strictly regulated. In Wyoming, marriage between first cousins is not permitted.
According to Wyoming Statutes § 20-1-106, individuals may not marry their immediate family members, which includes:
- Parent and child
- Siblings (full or half)
- Grandparent and grandchild
- Aunt/uncle and niece/nephew
- First cousins
This means that first cousins cannot legally marry in the state of Wyoming, even if they are both consenting adults.
What About Second Cousins or Distant Relatives?
Second cousins and more distant relatives are not restricted under Wyoming law when it comes to either dating or marriage. This is common across most U.S. states, as the degree of genetic relation is considered minimal.
In short:
- Second cousins can legally date and marry in Wyoming.
- The law specifically prohibits marriage only between first cousins and closer relatives.
Why Do Some States Allow Cousin Marriage While Others Don’t?
The legal stance on cousin marriage varies significantly across the U.S.
- Around 19 states allow first cousins to marry (such as California, New York, and Florida).
- 24 states ban first cousin marriages, including Wyoming, Texas, and Kentucky.
- The remaining states have conditional allowances (e.g., permitting marriage if the couple is past reproductive age or infertile).
The reasoning behind such laws often stems from concerns about genetic risks to offspring, religious or cultural norms, or outdated taboos. However, modern studies suggest that the actual genetic risk of first-cousin couples having children with health issues is often overestimated.
Are There Any Exceptions in Wyoming Law?
Currently, Wyoming does not offer any exceptions to its first cousin marriage ban. Even if a couple does not plan to have children or are past childbearing age, the law remains firm.
Additionally, Wyoming does not recognize first cousin marriages that were legally performed in other states or countries where such unions are allowed. This could affect things like spousal benefits, inheritance rights, or legal guardianship if the couple resides in Wyoming.
Social Acceptance vs. Legal Standing
Even when a relationship is legally permitted, it may not always be socially accepted. Dating a cousin—especially a first cousin—can still carry a stigma in many communities, including those in Wyoming. Cultural and familial reactions may vary, so anyone considering such a relationship should be prepared for both legal and social implications.
Conclusion
While laws surrounding cousin relationships might seem unusual or outdated to some, they continue to vary across the country. If you’re in a cousin relationship and live in Wyoming—or are considering marriage—it’s important to be informed about both state statutes and the potential legal consequences.
For those unsure about their specific situation, it’s always a good idea to consult with a family law attorney who understands Wyoming’s marriage laws and can help navigate any complex legal questions.
