Marriage Name Change in Montana

Agency: Montana Motor Vehicle Division (MVD). Deadline: Montana asks that you complete the Social Security update at least 24 hours before your MVD visit; MVD does not publish a fixed post-marriage deadline for the license update itself.

Montana's MVD requires you to update your name with the Social Security Administration at least 24 hours before applying for a new driver license or ID in your married name. MVD verifies your identity against SSA records at the time of your visit, and you'll need to bring supporting documents in person.

Bring these documents:

• Updated Social Security card or SSA confirmation (reflecting your new name)
• Certified copy of your marriage certificate from the Clerk of District Court
• Current Montana driver license or ID card
• Proof of Montana residency (as listed on MVD's required documents page)

The one order that matters is Social Security first, then your driver license — state offices verify your new name against SSA records. Your U.S. passport can be updated whenever it suits you; it is not required before your license.

Update Social Security first, then your Montana driver license — Montana agencies verify your new name against Social Security records, so going the other way causes rejections and wasted trips. Your U.S. passport is a separate, independent update: you do not need a new passport to get your license, and you can renew it whenever it suits your travel plans. Banks, employer, insurance, and the rest come after your license.
