Is It Illegal to Marry Your Cousin in California? Check out Here!

Cousin marriage is a subject of contention in various countries, characterized by diverse laws and social attitudes surrounding the practice. Cultural perspectives vary, with some societies viewing cousin marriage as a normal means of preserving family connections and ensuring compatibility, while others consider it taboo, citing genetic and moral concerns.

In the United States, the legality of cousin marriage differs from state to state, ranging from being legal in some regions to constituting a criminal offense in others. However, even in states where it is legal, the prevalence of cousin marriages is limited. According to a 2012 estimate, only around 0.2% of marriages in the U.S. involve first cousins. 

In this article, we delve into the legal aspects and societal perceptions of cousin marriage in California, one of the states permitting cousin marriage without restrictions.

Legal Considerations in California

In California, cousin marriage is not explicitly prohibited by law, allowing cousins to marry each other legally. State laws explicitly restrict closer relationships such as siblings but remain silent on cousin marriages. The marriage application form in California does not inquire about the relationship between applicants; instead, it confirms the absence of any legal impediments to marriage. 

However, the legality of cousin marriages in California may not be recognized in other states or countries. Some U.S. states may not acknowledge cousin marriages performed in California if they prohibit such unions within their jurisdictions. This could pose challenges for cousin couples relocating or visiting other states, particularly if they encounter issues related to divorce, property inheritance, or benefits. 


Similarly, some countries may not validate cousin marriages conducted in California if their legal systems prohibit such unions. This may impact cousin couples with international travel plans or dual citizenship, particularly if they face legal disputes or immigration-related matters. 

Therefore, couples considering cousin marriage in California should be cognizant of potential legal ramifications and challenges that may arise in other jurisdictions.

Social Perceptions of Cousin Marriage in California

Beyond legal considerations, cousin marriage carries social implications. In California, much like the rest of the U.S., cousin marriage is generally frowned upon and stigmatized within mainstream society. Many people associate cousin marriage with incest, genetic issues, and cultural backwardness. 

Cousin couples may encounter discrimination, prejudice, and harassment from various quarters, including family, friends, neighbors, employers, and strangers. They may grapple with feelings of isolation, shame, and guilt due to societal disapproval. Seeking support and acceptance from their communities and society at large may prove challenging. 

Additionally, cousin couples may need to address the health risks and ethical considerations associated with having children. While the genetic risks are often exaggerated, there is a slightly higher chance of birth defects or genetic disorders compared to non-related couples. Genetic counseling and testing may be necessary for cousin couples planning to have children, and they may encounter moral and religious objections from those viewing cousin marriage as unnatural or sinful. 

Cousin couples contemplating marriage in California should prepare for potential social challenges and pressures in their lives.


Cousin marriage remains a complex and controversial issue, intertwining legal, social, and personal facets. In California, cousin marriage is legally permitted but not widely embraced. Couples considering marriage in California should be mindful of the legal and social implications, seeking professional and personal guidance as needed. They should also respect differing viewpoints, finding a balance between their happiness and the well-being of their families and society.
