Minnesota Annulment and Prohibited Marriage Laws

Getting married, or not getting married, is a very personal decision based on a number of considerations. But since marriage is a legal contract between partners granted by the state, not all types of marriages are approved. In Minnesota and all other states, for instance, you may not marry someone if you have a previous marriage that has not been dissolved -- that is considered bigamy. Similarly, there are certain circumstances under which one or both parties may have the marriage annulled (or treated as if it never happened in the eyes of the law), such as the inability to consummate the marriage.

The basics of Minnesota's annulment and prohibited marriage laws are listed in the chart below. Additional articles and resources can be found in FindLaw's Marriage Law Overview section.

Same-Sex Marriage in Minnesota

Minnesota began recognizing same-sex marriages throughout the state in 2013, after state lawmakers passed a bill removing the ban. This legislation was influenced by a ballot initiative rejected by voters that would have prohibited same-sex marriage through a state constitutional amendment. As a result, Minnesota became one of the first states to legalize gay marriage through statute (as opposed to case law). Finally, in 2015, the U.S. Supreme Court found that state bans on same-sex marriage were unconstitutional. The case, Obergefell v. Hodges, supported the decision of states such as Minnesota and legalized same-sex marriage in states that had not yet done so.
