There are three ways to get married in Montana. The most common is ceremonial marriage. To do this you need a marriage license from your county Clerk of the District Court. The fee is $53 (in cash). The license is in effect as soon as you get it, and works for up to 180 days. Someone authorized by the state must perform the marriage. The marriage needs at least two witnesses.
You can also get married by common law or by declaration of marriage. These are both described later in this article.
You must be at least 16 years old. If you are 16 or 17, the law requires consent of your parents or a judge, as well as pre-marriage counseling. If you are 18, you are legally an adult and do not need consent.
There is no residency requirement in Montana for getting a marriage license.
The woman must get the medical certificate for ceremonial marriage. Then the couple must file a written declaration. This must be signed by both husband and wife and filed with the local Clerk of District Court. Contact your local Clerk of Court for more information. The fee for this is $53 (in cash).
You and your partner must do all of the following:
If you don't do all of these things, you might not have a common law marriage. Living together, even for a long time, does not create a common law marriage. Important property, support and inheritance rights, and benefits such as insurance, social security, and worker's compensation all depend upon whether or not you are married.
If you are married by common law, you will need a divorce to end the marriage. This is no different than if you had been married by ceremony or by declaration. If you have a question about whether or not you are married by common law you must talk to a lawyer. Each common case depends on its own facts, and a lawyer will need to help sort out the details.
