State laws dictate the grounds under which an annulment may be granted and which types of marriage are prohibited. Examples of marriages that are prohibited are those between closely related family members or those where a previous marriage was not ended either through a divorce or a spouse's death. In Montana, laws related to civil annulments and prohibited marriages are very similar to those of other states.
Montana Prohibited Marriages
In Montana, certain types of marriage are prohibited. These include marrying your first cousin or other closely related family member such as a sibling or parent. In addition, you can't get married if you already have a spouse. You'll have to have a formal divorce first. Also, you have to be of legal age, unless you obtain the consent of a parent or guardian.
Same-sex marriage is now legal in the state of Montana. In 2015, the U.S. Supreme Court ruled that same-sex marriage is protected and guaranteed under the Fourteenth Amendment's Equal Protection Clause. In that year, the U.S. Supreme Court did so in a case called Obergefell v. Hodges.
