Minnesota is a purely "no-fault" divorce state, meaning that you can't allege that your spouse's wrongdoing was the cause of the divorce. Instead, most divorces are based on the grounds that the parties have irreconcilable differences that have led to the breakdown of the marriage. However, fault may be considered by the court as a factor in dividing property or awarding alimony. To learn more about whether Minnesota uses fault as a determining factor in alimony and property issues, see Nolo's Essential Guide to Divorce, by Emily Doskow.
Effective August 1, 2013, the law in Minnesota allows same sex couples to get married or divorced in this state. To file for divorce in Minnesota, at least one party must be living in Minnesota for at least 180 days before starting the divorce case. A same sex couple may also file for divorce in Minnesota if they got married in Minnesota on or after August 1, 2013, and each party to the marriage now lives in a state that does not allow the dissolution of the parties' same sex marriage. See Minn. Stat. § 518.07, subd. 2.
