Your situation

Where did you buy the vehicle?
Online or in person
Depends on the county · County treasurer's officeThe agency's page only sends you to your County Treasurer's office. County pages differ: Cascade County offers an online portal (title paperwork must be at the office with all signatures before registration is completed online), Flathead County lists online services, Gallatin County has an online form for dealership purchases and for out-of-state title transfers where the lienholder sent the original title to its office, and Yellowstone County lists online renewals (all county-specific). The agency says to visit your County Treasurer's office and to check whether appointments are required or encouraged; an appointment can save you from a long line.

Common reasons people get turned away

  • Dealer paperwork can take several weeks to reach the county treasurer; confirm before you visit.
  • Cascade County (county-specific): a notarized Power of Attorney is required if you do business for another owner; for a vehicle newer than 11 years old it must be a Secure Power of Attorney listing the VIN and mileage.
  • New residents must apply for a Montana vehicle title and register their vehicles within 60 days of establishing residency.
