Massachusetts: Private-Party Vehicle Title Transfer Requirements
The short answer
The seller signs the assignment on the back of the Massachusetts title—filling in the actual odometer reading, sale date, and price—and both seller and buyer sign; no notarization is required. To register and title, the buyer first has a licensed Massachusetts insurance agent stamp and sign the Registration and Title Application, then files it with the assigned title at the RMV, paying a $75 title fee, the registration fee, and 6.25% sales tax. Apply for the title within 10 days; the plates stay with each owner, and the buyer must get an inspection sticker within 7 days of registering.

This is the general rule in Massachusetts. Ezel applies current Massachusetts law to your specific facts and answers with citations to the statutes.
| Governing law, agency, and scope | Mass. Gen. Laws ch. 90D (certificates of title) and ch. 90 (registration); administered by the Registry of Motor Vehicles (RMV), part of MassDOT. Ordinary same-state private sale of a currently Massachusetts-titled used passenger vehicle. Vehicles too old to be titled instead transfer on the previous registration plus a bill of sale. |
|---|---|
| Title assignment, owner signatures, and lien release | At delivery the owner executes on the certificate an assignment 'including the actual odometer reading and warranty of title' and delivers it to the buyer or the registrar (ch. 90D, § 15(a)); the buyer then executes the application for a new title (§ 15(b)). The RMV requires the back of the title to carry the signatures of both sellers and buyers and the recorded mileage, with no erasures, white-outs, or alterations. If a lienholder holds the certificate, it delivers the title for the transfer (§ 15(c)-(d)). |
| Notarization, witness, or agent verification | No notary or witness is required for the title assignment. Massachusetts instead requires an insurance step: a licensed Massachusetts insurance agent must complete, stamp, and sign the Registration and Title Application (RTA) to bind coverage before the RMV will register and title the vehicle. That agent stamp, not a notarization, is the distinctive Massachusetts verification. |
| Bill of sale requirement and contents | For a titled vehicle the assigned certificate of title is the proof of ownership; a bill of sale is supporting evidence. A bill of sale becomes mandatory only for a vehicle exempt from title because of its age, where the buyer presents the previous owner's registration plus the bill of sale in place of a title. The RMV also advises private buyers to get a proper title and bill of sale as good practice. |
| Odometer, damage, and title-brand disclosures | The seller must enter the actual odometer reading in the title assignment (ch. 90D, § 15(a)); the RMV requires mileage recorded in the proper area. Separately, the Massachusetts used-vehicle Lemon Law requires a private seller to tell the buyer about any known defect that impairs safety or substantially impairs use—regardless of price or mileage—and a buyer who proves a concealed known defect may cancel within 30 days. Salvage and total-loss vehicles follow the separate ch. 90D, § 20 salvage-title process. |
| Seller notice, plate handling, and liability | There is no separate private-seller report-of-sale filing to the RMV for an ordinary sale. Registration plates stay with the owner, not the vehicle: the seller keeps or cancels the plates and the buyer uses their own. An owner who delivers the vehicle and completes the § 15 steps 'shall not be held liable' for later operation or automobile-law violations, even before a new title issues (ch. 90D, § 15(e)); a seller not buying a replacement should cancel the plates and registration to stop excise-tax bills. |
| Buyer deadline, forms, tax, and fees | The buyer must apply for a certificate of title within 10 days (ch. 90D, § 4, per the RMV). To register and title, take the assigned title and the insurance-agent-stamped Registration and Title Application to an RMV Service Center. Fees: a $75 title fee plus the registration fee, and 6.25% sales/use tax computed on the sale price or NADA book value, whichever is higher. The sales/use tax is due to the Department of Revenue by the 20th of the month after purchase. |
| Inspection, emissions, insurance, and operation | Active Massachusetts motor-vehicle insurance is required before registration—the insurance agent stamps the RTA to certify it. After registering, the buyer must obtain a Massachusetts vehicle inspection sticker (the combined annual safety and emissions inspection) within 7 days. Under the 7 Day Transfer Law, a buyer 18 or older who has disposed of a previous vehicle may attach their existing plates to the newly purchased vehicle and drive for up to 7 days while completing the registration. |
| Penalties, rejection, and failed transfer | A transfer 'is not effective' between the parties and the state until the § 15 (and § 18) steps are done, though the complying seller is shielded from post-delivery liability (ch. 90D, § 15(e)). Late payment of the sales/use tax 'subjects you to penalties and interest' from the Department of Revenue. The RMV will reject an application or proof of ownership that has erasures, white-outs, or alterations, or that does not match the supporting documents; missing signatures, mileage, insurance, or tax can also stop the transfer. |

Requirements one by one
The seller assigns the title; both parties sign
Massachusetts keeps the transfer on the certificate. Chapter 90D, § 15(a) says
the owner "shall, at the time of the delivery of the vehicle, execute an
assignment including the actual odometer reading and warranty of title" and
deliver the certificate to the buyer or the registrar. The buyer then "promptly
after delivery" executes the application for a new title (§ 15(b)). On the back
of the title the RMV needs the signatures of both the seller and the buyer, the
odometer reading in the correct area, and no erasures, white-outs, or
alterations.
If a lender holds the title, § 15(c)-(d) lets the lienholder deliver it so the
transfer can go through.
No notary—but an insurance agent must stamp the application
Massachusetts does not notarize the title. Instead it front-loads insurance: a
licensed Massachusetts insurance agent must complete, stamp, and sign the
Registration and Title Application (RTA) to confirm active coverage before the
RMV will register and title the vehicle. That agent stamp is the step people
from other states do not expect.
A bill of sale matters mostly for older, title-exempt cars
For a titled vehicle, the assigned certificate is the ownership document, and a
bill of sale is just supporting evidence. A bill of sale becomes required only
when the vehicle is too old to be titled: the buyer then presents the previous
owner's registration plus the bill of sale in place of a title.
Odometer and the used-car Lemon Law disclosure
The seller enters the actual mileage in the title assignment (§ 15(a)).
Massachusetts adds a private-seller honesty rule: the used-vehicle Lemon Law
requires the seller to disclose any known defect that impairs safety or
substantially impairs use, on every private sale regardless of price or mileage.
A buyer who proves the seller hid a known defect may cancel within 30 days.
The buyer's 10 days, tax, and fees
The RMV, applying Chapter 90D, § 4, requires the buyer to apply for a
certificate of title within 10 days. Bring the assigned title and the
insurance-agent-stamped RTA to an RMV Service Center and pay a $75 title fee,
the registration fee, and 6.25% sales tax. For a private sale the tax is figured
on the sale price or the NADA book value, whichever is higher, and it is due to
the Department of Revenue by the 20th of the month after the purchase.
Plates stay with each owner; inspect within 7 days
Massachusetts plates belong to the owner, not the car. The seller keeps or
cancels the plates; the buyer uses their own. Under the 7 Day Transfer Law, a
buyer 18 or older who has disposed of a previous vehicle may bolt their existing
plates onto the new car and drive for up to 7 days while registering. After
registering, the buyer must get a Massachusetts inspection sticker (the combined
annual safety and emissions inspection) within 7 days.
What trips people up
- The insurance agent is a required stop. You cannot title and register a
Massachusetts car without a licensed insurance agent stamping the RTA first. - The tax deadline is a calendar date, not a countdown. Sales/use tax is due
by the 20th of the month after purchase; paying late brings DOR penalties and
interest, even if you titled on time. - The plates do not travel with the car. Each owner keeps their own plates;
the buyer's 7-day grace is for the buyer's own plates, not the seller's. - Alterations void the paperwork. Any erasure or white-out on the title or
application gets the transfer rejected.
Common questions
Does a Massachusetts car title need to be notarized?
No. The seller and buyer sign the title assignment without a notary. The extra
step is an insurance agent's stamp on the Registration and Title Application.
How long does the buyer have to title the car?
Apply for the title within 10 days (ch. 90D, § 4). Sales/use tax is separately
due by the 20th of the following month.
Do I keep my license plates when I sell my car?
Yes. Massachusetts plates stay with the owner. Cancel them if you are not moving
them to a replacement vehicle, to stop excise-tax bills.
Do I need a bill of sale?
For a titled car the assigned title is what counts, though a bill of sale is
good practice. It is required only for a vehicle too old to be titled, alongside
the previous registration.
