Annulling a Marriage

Judicially decreed annulment of a marriage is extremely rare under Wyoming law. This is because, unlike in many other states, the grounds for annulment in Wyoming are very limited.

Wyoming Statute §20-2-101 says that marriages contracted in Wyoming are void without any decree of divorce if either spouse has another husband or wife living at the time the marriage was performed, or if either party was mentally incompetent at the time the marriage was performed, or if the parties are parent and child, grandparent and grandchild, brother and sister of half or whole blood, uncle and niece, aunt and nephew, or first cousins.

The statute goes on to say that any marriage wherever performed is voidable if either party was under the age of consent (unless a judge gave his consent) at the time of the marriage, or if the parties separated while still minors and never lived together after their separation, or if the consent to marry given by one of the parties was obtained by force or fraud and there was no subsequent cohabitation by the parties.

A marriage that is void or voidable under one of the grounds listed above is annulled when one of the parties files a petition for an annulment in the district court of the judicial district where one of the parties or both of them resides and the court proceedings are similar to the proceedings for a divorce. The statute says that upon due proof the court will issue a decree of nullity.
