What to do with Montana plates after moving to New Mexico
The answer can be return, cancel, destroy, recycle, or keep. Follow the reviewed Montana instruction only after the New Mexico registration and insurance handoff are safe.
Complete the replacement record
Title and register at an MVD field office with the ownership document, odometer reading, identity, two New Mexico residency proofs, and insurance evidence. The current new-resident page does not publish a general day-count deadline.
Bring a current insurance card, policy copy, or insurer letter showing the required liability coverage.
Cancel the Montana registration with MV60 after the new registration is active
After the destination registration is active, complete Montana MV60 and select permanent cancellation. Every listed owner must consent, and the plates must be removed when they remain in the owner's possession. Keep the signed form and submission proof with the destination registration before treating the old record as closed.
