Is It Illegal to Marry Your Cousin in Mississippi? Here’s What the Law Says

The idea of marrying a cousin might seem taboo to many people, but it’s a surprisingly common practice in certain parts of the world and even within the United States. While some states have strict bans against cousin marriages, others are more permissive. If you’re a resident of Mississippi and are wondering about the legal ramifications of marrying a cousin, read on for a deep dive into the state’s laws.

Mississippi’s Stance on Cousin Marriages

Mississippi is one of the states in the US that does allow first-cousin marriages. There is no specific legislation prohibiting marriages between people who are first cousins. Essentially, if you and your partner are legally old enough to marry and share the kinship of first cousins, your marriage would be considered valid under Mississippi law.

Historical and Cultural Context

  • Global Perspective: Cousin marriages have been historically common in various parts of the world, including Europe, the Middle East, and Asia. Often, these marriages were arranged for purposes of consolidating wealth, preserving family ties, or addressing cultural preferences.
  • US History: In the past, cousin marriages were more prevalent in the United States. However, starting in the late 19th century, many states began passing laws restricting marriages between close relatives due to concerns about genetic risks.

Scientific and Genetic Considerations

  • Increased Risks: Children born from first-cousin marriages have a slightly higher risk of birth defects and genetic disorders compared to children of unrelated parents. This risk increase is relatively small but still important to acknowledge.
  • Genetic Counseling: Couples considering a first-cousin marriage may benefit from genetic counseling. These sessions involve an assessment of family history and potential genetic risk factors, informing couples about any potential health concerns for their future children.
