What a blank auto bill of sale is and why you need one
A blank auto bill of sale is a document that records the transfer of a vehicle from one owner to another. It serves as proof that money or other value changed hands, and it protects both the buyer and seller by documenting the transaction in writing. When you buy or sell a car privately — not through a dealer — a bill of sale becomes your legal record of the deal.
The document itself is straightforward: it has spaces for the seller's name and address, the buyer's name and address, the vehicle identification number (VIN), the sale price, and the date of the transaction. Some versions include odometer readings or notes about the vehicle's condition. A blank bill of sale is a template you fill in by hand or on a computer before signing.
You need one because it protects you if a dispute arises later. If the buyer claims the car had hidden damage, or the seller claims they were never paid, the signed bill of sale is your evidence of what was agreed and when. It also serves as the starting point for the buyer's title transfer at the DMV — most states require it or will ask for it.
Key Takeaways
- A bill of sale documents the vehicle's VIN, the sale price, the names and addresses of both parties, and the date of sale.
- Both the buyer and seller should sign and keep a copy; some states require the seller to provide one to the buyer.
- You can read a blank template from your state's DMV website, use a generic template, or write one yourself as long as it includes the essential information.
- The bill of sale is not the same as the title — it is a supporting document that helps the buyer transfer the title into their name.
- Odometer readings and notes about the vehicle's condition should be included to prevent later disputes over mileage or defects.
Where to find a blank bill of sale template
Your state's DMV website usually offers a free blank bill of sale form specific to your state's requirements. Search "[your state] DMV bill of sale" to find the official version. If your state does not provide one, generic templates are available from legal document sites, though you should check your state's DMV to see if there are any specific fields or language required.
Some states have no official form and accept any bill of sale as long as it includes the essential information: both parties' names and addresses, the vehicle's VIN, the sale price, and the date. In those cases, you can use a generic template or even write one yourself on plain paper. The key is that both parties sign it and each keeps a copy.
If you are buying or selling through a private transaction, ask the other party whether they have a preferred template. Some people keep their own version from a previous transaction. As long as it covers the basics and both of you are comfortable with it, that works.
What information to include on the bill of sale
The essential fields are the seller's full name and address, the buyer's full name and address, the vehicle's VIN (found on the dashboard or in the title), the make and model of the car, the year, the sale price in dollars, and the date of the sale. Both parties must sign and print their names.
Beyond the basics, include the odometer reading on the date of sale. This protects the buyer by documenting the mileage at the time of purchase and prevents the seller from later claiming the car had lower mileage. It also helps the DMV verify the title history when the buyer applies for transfer.
You can also add a section for the vehicle's condition — for example, "sold as-is" or notes about any known defects. This is optional but useful if the buyer has seen the car and agreed to purchase it despite visible wear or mechanical issues. If there are no known defects, you can straightforward write "vehicle inspected and accepted by buyer" or leave that section blank.
How to fill in the bill of sale correctly
Use black or blue ink and write legibly, or type the information if you are filling it out on a computer. Do not leave blank spaces — if a field does not explore, write "N/A" or draw a line through it. This prevents someone from adding information after you have signed.
Enter the VIN exactly as it appears on the title or the vehicle itself. Mismatched VINs can delay the buyer's title transfer at the DMV. Double-check the spelling of both parties' names and addresses. The sale price should be written in numbers and words — for example, "$5,000 (five thousand dollars)" — to prevent disputes over the amount.
Both the buyer and the seller must sign and date the document in front of each other, or at minimum, each party should sign their own copy. Some states do not require a notary, but having the document notarized adds an extra layer of proof that both parties signed willingly. Check your state's DMV website to see if notarization is recommended or required.
When to sign the bill of sale and what happens next
Sign the bill of sale on the day of the sale, after the money has changed hands and the keys have been transferred. Both parties should sign the same document, or each should sign a copy that the other receives. Keep your signed copy in a safe place — you will need it if any dispute arises later.
For the seller, the bill of sale is your proof that you sold the vehicle and received payment. You should also notify your insurance company and your state's DMV that you no longer own the car, usually by submitting a release of liability or notice of sale form. This protects you if the buyer gets into an accident or receives a traffic ticket in the car.
For the buyer, the bill of sale is the first document you will need when you go to the DMV to transfer the title into your name. Bring the bill of sale, the original title signed by the seller, proof of insurance, and a completed title process form. The DMV will use these documents to issue a new title in your name. The timeline varies by state, but title transfers usually take one to four weeks.
Common mistakes to avoid when using a bill of sale
Do not sign a blank bill of sale or one with empty spaces. If you sign before all the information is filled in, the other party could add details you did not agree to. Similarly, do not accept a bill of sale that has been altered or crossed out without both parties' initials next to the change.
Do not rely on a bill of sale alone to prove ownership. The bill of sale is a record of the sale, but the title is the legal proof of ownership. As a buyer, you must transfer the title into your name at the DMV to be the official owner. As a seller, you remain the legal owner until the buyer completes the title transfer, so notify your state promptly that you have sold the vehicle.
Do not assume the bill of sale is the same across all states. Some states have specific requirements for the format, wording, or fields. Before you sign, check your state's DMV website to see if there is an official form or any rules about what must be included. Using the wrong form can delay the buyer's title transfer.
Bill of sale versus title: what is the difference
The bill of sale is a record of the transaction — it shows that a sale occurred, when it occurred, and for how much money. The title is the legal document that proves who owns the vehicle. You need both: the bill of sale to document the sale, and the title to prove ownership.
When you buy a car, the seller gives you the signed title and a bill of sale. You take both to the DMV, which cancels the seller's title and issues a new one in your name. The bill of sale is supporting evidence; the new title is your proof of ownership. Once the DMV issues your title, the bill of sale's main job is done, though you should keep it in your records in case a dispute arises later.
If you are selling a car, you sign the title over to the buyer and provide a bill of sale. The buyer takes both documents to the DMV. You keep a copy of the bill of sale as proof that you sold the vehicle and received payment. You do not keep the title — that goes to the buyer.
Frequently Asked Questions
Can I write a bill of sale on a piece of paper instead of using a form?
Yes, in most states. As long as the document includes both parties' names and addresses, the vehicle's VIN, the sale price, and the date, and both parties sign it, the DMV will usually accept it. Check your state's DMV website to confirm there are no specific format requirements, but a handwritten bill of sale is legally valid in most places.
Do I need to get the bill of sale notarized?
Notarization is not required in most states, but it is recommended. A notary's signature proves that both parties signed the document in front of a neutral witness, which adds credibility if a dispute arises later. Some states recommend it; a few require it. Check your state's DMV website or ask the DMV directly whether notarization is necessary.
What if I lost my copy of the bill of sale after the sale?
If you are the seller, contact the buyer and ask for a copy. If you are the buyer, check your records or ask the seller. If neither party has a copy, you can still transfer the title at the DMV using the original title and a completed process, though the process may take longer. Going forward, keep your bill of sale in a safe place with your other vehicle documents.
Can the buyer transfer the title without a bill of sale?
It depends on your state. Some states require a bill of sale as part of the title transfer; others do not. The DMV will tell you what documents are needed when you explore. If your state does not require it, the buyer can transfer the title using just the signed title and the process form, but having a bill of sale is still a good idea for both parties' protection.
Should I include the trade-in value if I am trading in my old car toward a new one?
If you are selling the car outright for cash, the bill of sale should show the cash price. If you are trading it in at a dealership, you typically do not need a bill of sale — the dealer handles the paperwork. If you are selling it privately and the buyer is giving you cash plus a vehicle in trade, you can note the cash amount and describe the trade-in vehicle, or you can list only the cash price. Consult your state's DMV for guidance on how to handle trades in your area.
