Thinking about cousin marriage in New Jersey and wondering what the law says? The topic might raise eyebrows socially, but when it comes to legal rules, New Jersey is clear and straightforward.
Is Cousin Marriage Legal in New Jersey?
Yes, marrying your cousin is legal in New Jersey.
The state’s marriage laws do not prohibit or restrict marriage between first cousins or more distant relatives. This means:
You can legally marry your first cousin (your aunt or uncle’s child).
You can also legally marry your second cousin or any more distant relative.
New Jersey law only bans marriage between very close blood relatives — such as parents and children, siblings, and uncles or aunts with their nieces or nephews. Cousins are not included in that list, which places New Jersey among the states that allow cousin marriages without restrictions.
What the Law Specifically Says
The New Jersey Revised Statutes (NJ Rev Stat § 37:1-1) outline the types of familial relationships where marriage is strictly forbidden. These include:
Parent and child
Brother and sister
Aunt and nephew
Uncle and niece
Importantly, first cousins are not listed, which confirms that the state permits cousin marriages.
Is Genetic Counseling Required?
While the law does not demand it, genetic counseling is often recommended for couples who are closely related. This is to assess any potential health risks for future children.
Generally, the risk of genetic disorders in first-cousin offspring is only slightly higher than in the general population. But if intermarriage has happened across several generations in a family, risks may increase.
What About Cultural and Social Views?
Even though it’s legal, cousin marriage may still carry social or cultural stigma. Some communities may be more accepting, especially where cousin marriages are common, while others may disapprove. It’s a personal decision that may involve navigating family expectations and cultural norms.
