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

The topic of marrying a first cousin often provokes strong reactions, ranging from curiosity to disapproval. While marrying one’s cousin might be considered unusual or even taboo in some cultures, it’s a more common and accepted practice in others. Legality across the globe varies greatly; some nations have strict bans against cousin marriages, whereas others have little to no regulation on the matter.

In the United States, the legal landscape for marrying your cousin is a patchwork of different state laws. This article will focus specifically on the state of New Jersey, exploring the legality and surrounding issues of cousin marriages.

The Legality of Cousin Marriage in New Jersey

Yes, it is currently legal to marry your first cousin in New Jersey. It’s important to understand the historical context of this law. In the past, New Jersey, like many states, prohibited cousin marriages. However, this shifted in 1979, when laws criminalizing incest were revised, decriminalizing relationships between cousins. While civil law may no longer prohibit the act, there may still be social and cultural views that influence opinions on it.

At present, there are no specific restrictions or additional requirements in New Jersey for first cousins who want to marry. The marriage application process is the same as it would be for any other couple.

Reasons Behind Laws on Cousin Marriage

The primary reasons cited for laws prohibiting cousin marriage usually fall into three categories:

  • Concerns about Potential Genetic Risks: There is a prevailing concern that children born from marriages between close relatives may have a higher risk of genetic disorders. While this risk does exist, it is often overstated. The increased risk is relatively small unless there’s a family history of a specific genetic condition.
  • Religious and Moral Arguments: Some religious and cultural traditions strongly oppose cousin marriages, citing various ethical and scriptural reasons for their stance.
  • Changing Social Attitudes: With globalization and increasing awareness of diverse practices, social attitudes about cousin marriages are evolving, gradually becoming more accepting.
