What a Texas bill of sale is and why you need one
A bill of sale is a written record that you sold a vehicle to someone else and they paid you for it. In Texas, it is not required by law to transfer ownership — the title document itself does that — but a bill of sale protects both the seller and the buyer by creating a paper trail of the transaction. If you sell a car privately, a bill of sale documents the sale price, the vehicle details, the date, and both signatures. It becomes proof that you no longer own the vehicle if something goes wrong after the sale, and it gives the buyer proof of purchase if they need to show it to a lender or insurance company.
The Texas Department of Motor Vehicles does not mandate a bill of sale, but many private sales include one anyway because it answers questions that come up later. If the buyer gets into an accident and the previous owner is sued, a signed bill of sale shows you transferred ownership on a specific date. If the buyer never registers the vehicle and it racks up parking tickets, the bill of sale is your defense that you are not responsible. For the buyer, it proves they paid for the vehicle and what they paid, which matters if they finance it or insure it.
Key Takeaways
- Texas does not legally require a bill of sale to transfer vehicle ownership, but one protects both parties by documenting the sale price, date, and vehicle identification.
- The bill of sale should include the vehicle's VIN, year, make, model, sale price, odometer reading, and the full names and signatures of both buyer and seller.
- You can use the Texas DMV's optional form or write your own bill of sale as long as it includes all required information and is signed by both parties.
- The buyer needs the bill of sale along with the title to register the vehicle at the Texas DMV within 30 days of purchase.
- Keep a copy of the signed bill of sale for your records even after you sell the vehicle, in case questions arise about the transaction later.
What information must go on a Texas bill of sale
A bill of sale should include the vehicle's VIN (Vehicle Identification Number), year, make, model, and color so there is no confusion about which vehicle changed hands. It must also show the sale price in dollars, the odometer reading at the time of sale, and the date of the transaction. Both the seller and buyer must print their full legal names and sign the document. If either party is a business, include the business name and the person's title or role.
You should also note whether the vehicle is being sold as-is, with any known defects disclosed. For example, if the transmission needs work or the check engine light is on, write that down. This protects the seller from later claims that the buyer did not know about the problem, and it protects the buyer by creating a record of what they were told at the time of sale. Some sellers add a line stating the vehicle is sold with no warranty, which is common in private sales.
The bill of sale does not need to be notarized in Texas, though some buyers or lenders may ask for it. A notary public can stamp and sign the document for a small fee if you want that extra layer of authentication, but it is not required by the state.
Using the Texas DMV form or writing your own
The Texas Department of Motor Vehicles provides an optional bill of sale form, but it is not the only way to document the sale. You can read the form from the DMV website or write your own bill of sale as long as it includes all the information listed above. Many people use a straightforward one-page document with the seller's and buyer's information, vehicle details, price, and signatures.
If you write your own, keep the language plain and straightforward. You do not need legal jargon — just state the facts: "I, [seller name], sold the vehicle described below to [buyer name] on [date] for [price]." Include the VIN, odometer reading, and any known issues. Both parties sign and date it. A handwritten bill of sale is legally valid in Texas as long as both parties sign it and it contains the key information.
Some sellers and buyers prefer the DMV form because it is a standard document that lenders and insurance companies recognize when ready. Others use a bill of sale template from a legal website or create their own. The form you use matters less than making sure all the required details are there and both parties have signed copies.
What happens after you sign the bill of sale
Once both parties sign the bill of sale, the buyer becomes the legal owner of the vehicle, but they still need to register it with the Texas DMV to get a new title in their name. The buyer should take the bill of sale, the current title, proof of insurance, and proof of residency to a local DMV office or an authorized agent within 30 days of the purchase. The DMV will issue a new title showing the buyer as the owner.
As the seller, your job is done once you sign the bill of sale and hand over the title. However, you should keep a copy of the signed bill of sale for your records. If the buyer does not register the vehicle and it gets towed or ticketed, or if it is involved in an accident, you want proof that you transferred ownership on a specific date. Some sellers also notify their insurance company that they no longer own the vehicle, which removes it from their policy.
If you are trading in a vehicle at a dealership, the dealership will handle the bill of sale and title transfer. If you are selling privately, you and the buyer are responsible for making sure the paperwork is correct and signed.
Common mistakes to avoid when writing a bill of sale
The most common mistake is leaving out the VIN or writing it incorrectly. The VIN is the unique identifier for the vehicle, and if it does not match the title, the DMV will not process the registration. Double-check the VIN on the title and the vehicle itself before you write it on the bill of sale. Another frequent error is not including the odometer reading, which the buyer will need when they register the vehicle.
Some sellers forget to sign and date the bill of sale, or they sign it but the buyer does not. Both signatures are necessary for the document to be valid. If you are selling to someone out of state or out of the country, make sure you understand their state's or country's requirements for a bill of sale, because they may need additional information or a notarized copy.
Do not leave the sale price blank or write "cash" without a dollar amount. The price matters for tax purposes and for the buyer's insurance and financing. If the buyer is paying in installments, note that on the bill of sale and include the terms — for example, "$5,000 down, $200 per month for 24 months." This protects both parties if there is a dispute about how much was owed.
When a bill of sale is especially important
A bill of sale becomes critical if you are selling a vehicle with a lien on it — that is, if you still owe money to a lender. In that case, the bill of sale documents that the buyer is aware of the lien and agrees to take on the debt or pay it off. You should also use a bill of sale if you are selling a vehicle that has been in an accident, has high mileage, or has mechanical issues. Documenting those facts in writing protects you from later claims that the buyer did not know about them.
If you are selling a vehicle to a family member or friend, a bill of sale may feel unnecessary, but it is still a good idea. It keeps the relationship clear and prevents misunderstandings about whether the vehicle was a gift or a sale, and at what price. If the buyer later finances or insures the vehicle, they will have proof of purchase.
Frequently Asked Questions
Does Texas require a bill of sale to transfer a vehicle?
No, Texas does not legally require a bill of sale. The title document itself transfers ownership. However, a bill of sale is strongly recommended because it creates a record of the sale and protects both the seller and buyer if questions arise later.
Can I sell a car without a title in Texas?
No. The title is the legal proof of ownership, and you cannot transfer ownership without it. If you have lost the title, you must request a replacement from the Texas DMV before you can sell the vehicle. The buyer will also need the title to register the vehicle in their name.
What if the buyer does not register the vehicle after I sell it?
If you have a signed bill of sale, you have proof that you transferred ownership on a specific date. Keep that copy. If the vehicle is later towed, ticketed, or involved in an accident, you can show the bill of sale to prove you no longer owned it. You may also want to notify your insurance company and the DMV that you sold the vehicle.
Do I need to get the bill of sale notarized?
No, notarization is not required in Texas. However, some lenders or out-of-state buyers may request a notarized copy. If you want one, you can take the signed bill of sale to a notary public, who will verify your identity and stamp the document for a small fee.
What should I do if the buyer wants to pay in installments?
Write the payment terms clearly on the bill of sale — for example, the down payment amount, the monthly payment, the number of months, and the total price. Both parties should sign and keep a copy. Consider whether you want to keep the title until the final payment is made, which gives you security if the buyer stops paying.
