Cousin Marriage Laws are laws that regulate whether or not cousins can get married to one another. In most case, the word "cousin" refers to first cousins; usually the law will specify if they are referring to other terms such as first cousins once removed or second cousins. Cousin marriage laws are sometimes closely related to incest laws and other types of sex crime laws.

Which States Prohibit Cousin Marriages?

Currently, several states prohibit marriages between first cousins. These states are: Arkansas, Delaware, Idaho, Illinois, Kansas, Kentucky, Louisiana, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, South Dakota, Texas, Utah, Washington, West Virginia, Wisconsin, and Wyoming.

Some states have additional restrictions or details regarding their cousin marriage laws. For instance, Arizona allows cousin marriages, but only if at least one spouse is unable to reproduce. In Maine, cousin marriages or relations may be considered a civil violation punishable by a slight fee. So, the legality of cousin marriages varies widely from state to state.

In addition to marriage rules, some states also prohibit any sexual relations or cohabitation between cousins for relationship purposes.

Are Cousin Marriage Licenses from Out of State Valid?

Again, this depends on the state. For instance, some states such as Arizona, Illinois, and others consider out-of-state cousin marriages to be void. Other states like California, Florida, and many others do not void out-of-state cousin marriages.

Lastly, cousin marriage laws can also get quite technical. For example, some states make many distinctions between types of cousins as well as half-cousins and adopted cousins. A general rule of thumb is that the more distant the blood relationship is between the parties, the more likely it is that states will allow a marriage to occur between them.
