Verified against Montana District Court and .gov sources · Last verified July 16, 2026.

What it costs
No court petition needed to take a spouse's name
District Court in the county where you live
Step by step
- 1
Order a certified copy of your marriage certificate from the Clerk of District Court in the Montana county where your marriage license was filed — in Montana the county clerk, not the state, issues the certified record, and this copy is your legal proof of the new name.
- 2
Update Social Security first with Form SS-5 (free); the new card takes about 7–10 business days and the Montana MVD will verify your name against SSA records.
- 3
Take the certified marriage certificate and your identity documents to a Montana MVD Driver Exam Station (by appointment) to update your driver's license or ID.
- 4
Update your US passport (Form DS-5504 is free if issued within the last year), then banks, employer, and USPS.
Official forms
Every link goes to the official court or government host — never a paid re-host.
- • Montana marriage records are held by the Clerk of District Court in the county where the license was purchased — not necessarily where the ceremony took place.
- • No court order is required to take a spouse's surname; the certified marriage certificate is sufficient proof.
Then update your IDs
Once you have the certificate, update Social Security first, then your Montana license, then your passport and accounts.
