How to Sell a Car Privately in Massachusetts: Title, Plates and Lemon Aid Rules
To sell a car privately in Massachusetts, sign the title over to the buyer (with the sale date, price and odometer reading), give them a bill of sale, remove your license plates, then cancel your registration with the RMV (or transfer the plates to your next car) before you cancel your insurance. Massachusetts’ Lemon Aid law applies to private sales too: if the car fails inspection within 7 days of the sale and repairs would cost more than 10% of the price, the buyer can cancel the sale for a refund. You must also disclose known defects that affect safety or use.
Selling your car yourself in Massachusetts usually gets you more money than a trade-in, but the state has a few rules that private sellers need to know, especially the Lemon Aid law and the steps for cancelling your registration and plates.
This guide walks through a private sale in Massachusetts from start to finish.

How to Sell a Car Privately in Massachusetts
Find the Massachusetts title in your name. If there is a loan, pay it off and get the lien release or the clear title from the lender first. If it is lost, apply for a duplicate with the RMV.
Check values on pricing guides, gather service records, clean the car and list it with clear photos and an honest description.
Tell buyers about any problems you know of that affect safety or use. Under Massachusetts law a buyer may be able to cancel the sale if you hid one.
Sign the seller section of the title, enter the sale price, date and odometer reading, and give the buyer a signed bill of sale. Keep copies.
Use cash checked at your bank or a cashier’s check verified with the issuing bank before you hand over the title and keys.
Take off your plates. Cancel the registration with the RMV (online or in person) or transfer the plates to another vehicle, then cancel or move your insurance.
Massachusetts Lemon Aid Law for Private Sales

Many sellers are surprised that Massachusetts’ used vehicle protections cover private sales, not just dealers. According to the state’s consumer guidance:
- Failed inspection rule: if the car fails a Massachusetts safety or emissions inspection within 7 days of the sale and repairs would cost more than 10% of the purchase price, the buyer can cancel the sale and get a refund.
- Buyer’s deadline: the buyer must notify you and return the car within 14 days of the sale, with a written statement of why it failed and a repair estimate.
- Hidden defects: if the buyer can prove you knew of a defect that impairs safety or use and did not disclose it, they may cancel within 30 days.
- It applies to cars and motorcycles bought for personal or family use, regardless of age or mileage.
The best protection is to get the car inspected or checked before you list it, and to write any known issues on the bill of sale.
