Michigan Annulment and Prohibited Marriage Laws

Annulment is the legal process of declaring a marriage invalid, which is different than a divorce, while each state has laws prohibiting certain types of marriage. Grounds for annulment in Michigan include being underage, legally insane, physically incapable of consummating the marriage, and marriage by force or fraud.

Same-Sex Marriage in Michigan

Michigan annulment and prohibited marriage laws banned same-sex marriage, although same-sex unions performed during the brief time it was legal in Michigan were recognized by the federal government. In 2015, however, the U.S. Supreme Court issued a decision on the landmark case Obergefell v. Hodges, finding that denial of marriage to same-sex couples and failure to acknowledge the marriages of same-sex couples from other states constituted a violation of the Fourteenth Amendment's Equal Protection guarantees. Since that time same-sex marriage has been available in Michigan and all other states.
