Quick answer: a surviving spouse uses the Affidavit of Surviving Spouse directly at the RMV — no probate at all. Anyone else needs a court-appointed personal representative first.
A legal presumption that skips the estate entirely
What the surviving spouse actually submits
A new title and registration require the decedent's certificate of title assigned by the surviving spouse, a completed Registration and Title Application (stamped by an insurance agent if the car will stay registered), an Affidavit of Surviving Spouse, and a copy of the death certificate listing the spouse's name — all in person at any RMV Service Center.
Everyone else needs the court first
All other transfers of a decedent's automobile must go through a court-appointed administrator or executor. Once appointed, that person signs the original certificate of title, provides a bill of sale detailing the transaction, and gives the buyer a copy of the death certificate and the certificate of appointment.
Registration status can hold up the transfer
The registration must be active to process the surviving spouse transaction. An expired registration can be renewed once in the deceased spouse's name first; a suspension, revocation, or non-renewal action must be resolved before the transfer can proceed.
A local probate attorney can review your estate — many offer a free consultation.
The RMV processes surviving spouse transactions the same way at any Service Center statewide — in Suffolk, Middlesex, Norfolk, or any other county — regardless of which county's Probate and Family Court would otherwise have jurisdiction.
