How to Get Married in Montana (2026)
Reviewed by DocDraft Legal Team · Montana · Last updated 2026-05-18
Getting married in Montana means working through Montana-specific rules on the marriage license, the timing around it, and the ceremony itself. On the timing side: A license to marry is effective upon issuance. The window during which the license remains usable: 180 days. Common-law-marriage status: Recognized. This guide walks the Montana marriage-license steps, the documents required, and the officiant rules that apply.
Key Considerations
The Montana marriage code carries two timing layers. The first is the waiting period between issuance and lawful solemnization: A license to marry is effective upon issuance. The second is the license's validity period, after which a fresh license is required: 180 days. See the state agency website. Both are statutory; neither is negotiable with the clerk.
Two formation rules complete the Montana marriage picture. Recognized. A marriage may be solemnized by a judge of a court of record, by a public official whose powers include solemnization of marriages, by a mayor, city judge, or justice of the peace, by a notary public authorized pursuant to 1-5-630, by a tribal judge, or in accordance with any mode of solemnization recognized by any religious denomination, Indian nation or tribe, or native group. The first tells you whether Montana will recognize a marriage that never went through a ceremony at all; the second tells you which ceremonies the state will recognize.
Two of the first questions any Montana couple asks about a wedding are what the marriage license costs and who is old enough to apply. On the fee side, 53. On the age side, A party 16 or 17 years of age requires consent of both parents (or the custodial parent or guardian), must complete at least two marriage counseling sessions, and must receive judicial approval from the district court. See the state agency website. Confirm both with the issuing office before scheduling the ceremony.
