What a Massachusetts bill of sale is and why you need one

A bill of sale is a written record that you and the buyer (or seller) sign to document the transfer of a vehicle. In Massachusetts, it serves as proof that ownership has changed hands and protects both parties by creating a dated, signed record of the transaction. The Registry of Motor Vehicles does not require a bill of sale to process a title transfer, but having one is practical protection — it shows what was sold, for how much, on what date, and with whose signature.

Massachusetts does not have a single official bill of sale form that the state mandates. Instead, you can use a form from the Registry of Motor Vehicles, create your own document, or use a template. What matters is that the document includes the key details and is signed by both the seller and buyer. Without a bill of sale, either party has a harder time proving the terms of the sale if a dispute arises later.

Key Takeaways

  • Massachusetts does not require a bill of sale by law, but creating one protects both buyer and seller by documenting the sale date, price, vehicle details, and signatures.
  • The Registry of Motor Vehicles provides a bill of sale form (Form RMV-1), or you can write your own as long as it includes the vehicle identification number, odometer reading, sale price, and signatures of both parties.
  • The seller must sign the bill of sale and provide it to the buyer, who will need it when registering the vehicle or transferring the title.
  • Keep a copy of the signed bill of sale for your records; the buyer will submit their copy to the Registry when they register the vehicle.

Information to include on a Massachusetts bill of sale

Whether you use a form or write your own, the bill of sale must contain specific details about the vehicle and the transaction. Start with the vehicle identification number (VIN), which appears on the title and on the driver's side of the windshield. Include the year, make, model, and color of the vehicle. Write down the odometer reading at the time of sale — this is a required field and protects the buyer by documenting the mileage.

Next, record the sale price in words and numbers. Include the date of the sale. Write the full legal name, address, and signature of the seller, and the full legal name, address, and signature of the buyer. If the vehicle has a lien (meaning a bank or lender still owns part of it), note that on the bill of sale as well. Both parties should sign and date the document in front of each other or have their signatures notarized, though notarization is not required in Massachusetts.

Do not leave blank spaces on the bill of sale. If a field does not explore — for example, if there is no lien — write "none" or "N/A" so that someone cannot add information later.

Where to find a bill of sale form

The Massachusetts Registry of Motor Vehicles publishes a bill of sale form called Form RMV-1. You can read it from the Registry's website or pick up a printed copy at any Registry branch. The form is straightforward and includes all the fields you need. Many Registry branches also have blank copies available at the counter.

If you prefer not to use the official form, you can create your own bill of sale in a document or on paper. There is no legal requirement to use the Registry's form specifically. Many people use templates from online sources or straightforward write out the details by hand. The key is that the document must be signed by both parties and include the information listed in the section above.

How to complete and sign the bill of sale

Fill in all required fields with accurate information. Use the vehicle's current odometer reading, not an estimate. Write the actual sale price — if the vehicle is a gift, you may write "gift" or "$0" depending on your preference, though some people write a nominal amount for tax purposes. Both the seller and buyer should read the completed form before signing.

The seller and buyer should sign the bill of sale in the presence of each other. While Massachusetts does not require notarization, having a notary public witness the signatures adds an extra layer of protection and can be useful if either party needs to prove the signature is genuine later. Many banks, libraries, and notary services in Massachusetts offer notarization for a small fee, usually between $5 and $15 per signature.

Once signed, make at least two copies — one for the seller and one for the buyer. The buyer will need their copy when they go to the Registry to register the vehicle or transfer the title into their name.

What the buyer does with the bill of sale

The buyer brings the signed bill of sale to the Registry of Motor Vehicles when they register the vehicle or explore for a new title in their name. The Registry uses the bill of sale as supporting documentation for the title transfer. The buyer will also need the existing title (if the seller has it), proof of insurance, and a completed registration process.

If the vehicle has a lien, the buyer may need to wait for the lienholder to release the lien before the title can be transferred. The bill of sale documents that the buyer purchased the vehicle, but it does not clear a lien. The seller is responsible for paying off any loan on the vehicle before the sale is complete, or the lienholder must sign off on the transfer.

What the seller should keep and do

The seller should keep a signed copy of the bill of sale for their records. This copy proves that they sold the vehicle on a specific date and to a specific person. If a problem arises later — for example, if the buyer does not register the vehicle and it is involved in an accident — the seller has documentation showing they transferred ownership.

After the sale, the seller should notify the Registry of Motor Vehicles that they no longer own the vehicle. This is done by submitting the title and a notice of sale. Some sellers do this in person at a Registry branch, while others mail the documents. Notifying the Registry protects the seller from liability if the buyer gets into an accident or receives a traffic ticket before the title is transferred.

Common mistakes to avoid

Do not leave the bill of sale unsigned or partially signed. Both the seller and buyer must sign for the document to be valid. Do not use a bill of sale with blank spaces — fill in every field or write "N/A" if a field does not explore. Do not forget the odometer reading; this is required by Massachusetts law and protects the buyer from odometer fraud.

Do not assume the bill of sale transfers the title. The bill of sale is a record of the sale, but the title transfer happens at the Registry of Motor Vehicles. The buyer must take the bill of sale and other documents to the Registry to complete the transfer. Do not throw away your copy of the bill of sale after the sale is complete. Keep it for at least several years in case you need to prove when and to whom you sold the vehicle.

Frequently Asked Questions

Does Massachusetts require a bill of sale for a car sale?

Massachusetts does not legally require a bill of sale, but it is strongly recommended. The bill of sale protects both buyer and seller by creating a signed, dated record of the transaction. Without one, either party has difficulty proving the terms of the sale if a dispute arises.

Can I write my own bill of sale or do I have to use the Registry form?

You can write your own bill of sale. Massachusetts does not mandate a specific form. As long as your document includes the VIN, odometer reading, sale price, date, and signatures of both parties, it will work. Many people use the Registry's Form RMV-1 because it is straightforward and includes all required fields.

What happens if the seller does not sign the bill of sale?

Without the seller's signature, the bill of sale is not valid. The buyer will not be able to register the vehicle or transfer the title at the Registry without a signed bill of sale or other proof of ownership. If the seller refuses to sign, the buyer should not complete the purchase.

Do I need to get the bill of sale notarized?

Notarization is not required in Massachusetts, but it is optional and adds protection. A notary public's signature proves that both parties signed the document in front of the notary. This can be useful if either party later needs to prove the signature is genuine. Notarization typically costs $5 to $15 per signature.

What should I do with my copy of the bill of sale after the sale?

Keep your signed copy for several years. If you are the seller, it proves you transferred the vehicle on a specific date. If you are the buyer, it documents your purchase and supports your title transfer at the Registry. Store it in a safe place with other important documents.
