Legal Separation and Annulment in Michigan

Yes. A spouse may file an action for separate maintenance in circuit court on the same no-fault ground as a divorce. If the other spouse files a counterclaim for divorce and the ground is proven, the court enters a divorce instead of separate maintenance. Property may be divided and spousal support ordered in a separate maintenance judgment.

A marriage performed in Michigan is void if the spouses are too closely related by blood or marriage, if either spouse was already married, or if either spouse was not legally capable of marrying. A marriage is also void if a spouse was under the age of consent and the couple separated during that time and did not live together afterward, or if a spouse's consent was obtained by force or fraud and the couple did not voluntarily live together afterward. Either spouse may file in circuit court to have the marriage declared void, using the same procedure as a divorce. Children of a void marriage are legitimate.
