In the United States, the laws regarding cousin marriage differ from state to state.

This article will delve into the legality of marrying your cousin in the state of Florida, examining historical context, the current law, potential benefits and risks, and frequently asked questions about this topic.

The concept of cousin marriage sparks a range of reactions, from curiosity to disapproval. While the idea may seem taboo to some, it has a long history across various cultures. The legality of cousin marriage, however, is not uniform. Florida has specific laws regarding marrying within familial relationships.

Historical Perspective on Cousin Marriage

Historically, cousin marriage was quite common and sometimes even preferable. It was seen as a way to strengthen family ties, consolidate wealth and property, and maintain cultural traditions. Famous examples of cousin marriages include Charles Darwin and Emma Wedgwood, Albert Einstein and Elsa Einstein, and Queen Victoria and Prince Albert.

However, over time, as scientific understanding of genetics advanced, concerns about the potential health risks for offspring from such unions began to surface. Today, societal and legal views on cousin marriage are more divided, with some cultures continuing to embrace the practice while others heavily restrict or ban it.

Florida Law on Cousin Marriage

Florida Statute Section 741.21 directly addresses marriages between relatives:

  • Prohibited Marriages: “No person may marry a lineal ancestor or descendant or a sister or brother, whether the relationship is by the half or the whole blood.” [Florida Statutes 741.21]

This law clearly states that marriages between siblings, parents and children, grandparents and grandchildren, etc., are illegal. However, it does not specifically mention cousins. Therefore, first-cousin marriage is legal in the state of Florida.
