To marry in Montana, applicants must present government-issued photo identification and proof of age, along with a Social Security number. The state does not impose a residency requirement. Individuals aged 18 and older may marry without consent. Those aged 16 or 17 may marry with both parental consent and court approval. Applicants under age 16 are not permitted to marry in the state. No witnesses are required to obtain a marriage license.
Montana maintains a rubella-immunity blood test requirement for female applicants under age 50, making it the final state to retain such a requirement. However, the test is waivable; applicants may decline it by signing an informed-consent declination form. Marriage license fees are set by the applicant's county of application. Those seeking to marry should confirm all current requirements and procedures directly with their county clerk or through Montana's official state statutes, as eligibility rules and fees may change.
