Marrying Your First Cousin in Michigan is Illegal, but Here’s What the Law Says


Although it may not seem socially acceptable to others, marrying your first cousin is quite frequent in several cultures and parts of the world. Regarding the legitimacy and legality of cousin marriages, state laws in the US differ from one another. This article will concentrate on the state of Michigan, where it is unlawful to marry your first cousin, albeit there are some subtle legal distinctions.

What Do The Michigan Marriage Laws Say About First Cousins?

The website of the Michigan legislature makes it abundantly evident that it is against the law to wed first cousins in Michigan. Marriage between the following relatives is forbidden by law:

  • ancestors or descendants
  • brother and sister (blood or affinity)
  • aunt and nephew
  • uncle and niece
  • first cousins

Being connected by marriage, such as a spouse’s brother or a step-sibling, is called affinity. It is believed that any degree of first cousin kinship is prohibited because the legislation is silent on the minimum level of consanguinity (blood relation) needed for the prohibition to be in effect.

Are There Any Exceptions to the Law?

Michigan has a complete ban on first cousin marriages, in contrast to several other states that have certain exclusions or requirements for permitting first cousin marriages, such as age, infertility, or genetic testing. In Michigan, there are no unique rules or situations that would allow first cousins to get married.

However, as long as they were lawful in the jurisdiction in which they were performed, Michigan has always acknowledged first cousin marriages that were celebrated outside the state. This implies that if two first cousins moved to Michigan after getting married in a state or nation that permits cousin marriages, their union would be regarded as lawful and recognized in Michigan.

The Michigan Attorney General corroborated this in 1939, as did a number of court cases pertaining to inheritance and immigration. For instance, in the 1980 case of Matter of Balodis, the immigrant and Naturalization Service reversed a ruling that had refused immigrant status to his first cousin’s wife, a resident of Michigan. The court decided that their marriage, consummated in Latvia, was lawful and duly acknowledged in Michigan.

Does The Michigan Marriage Application Form Ask If You re Related?

You must apply for a marriage license at the county clerk’s office if you intend to get married in Michigan. You will be asked to fill out an application form with details about you and your intended spouse, including names, dates of birth, addresses, social security numbers, and parent names.

Additionally, the form will inquire as to if and how you are linked to one another. Checking one of the following boxes is required:

  • Not related
  • Related by blood
  • Related by marriage

If you select the “You are related by blood” box, you will be prompted to indicate the specific level of relationship, e.g., first cousin, second cousin, etc. In case you select the “you are related by marriage” box, you will have to indicate the specific kind of relationship, like being a step-sibling or your spouse’s sibling.

If you can demonstrate that your marriage was lawfully consummated in a state or nation that permits cousin marriages, you will be able to secure a marriage license in Michigan even if you are first cousins.
