A Texas bill of sale is a written record that you and the buyer (or seller) sign to document the transfer of personal property — usually a vehicle, boat, or equipment — and the price paid
Texas does not require a bill of sale by law for most personal property transactions, but having one protects both parties by creating a clear record of who owned what, when the ownership changed, and for how much. The document is especially important for vehicles because the Texas Department of Motor Vehicles uses it as evidence of ownership when you register a car or transfer a title. Without one, disputes over who actually bought or sold something can become expensive and time-consuming to resolve.
A bill of sale is not the same as a title or deed. A title is the legal document that proves ownership and is issued by the state. A bill of sale is the receipt and agreement that shows a transaction happened. For vehicles in Texas, you need both: the bill of sale to prove the sale occurred, and the title transfer to officially change the owner's name in the state system.
Key Takeaways
- Texas law does not require a bill of sale for personal property, but creating one protects both buyer and seller by documenting the transaction and price.
- For vehicles, the Texas Department of Motor Vehicles accepts a bill of sale as proof of ownership when you register or transfer a title.
- A bill of sale should include the names and addresses of both parties, a description of the item (including VIN for vehicles), the sale price, and the date signed by both parties.
- You can use a straightforward handwritten bill of sale or a printed form; Texas does not specify a required format, but both parties must sign it.
- The seller should keep a copy for their records, and the buyer should keep a copy to present to the DMV or other agencies when registering the item.
What information must go on a Texas bill of sale
A bill of sale should identify both the seller and the buyer by full legal name and address. This prevents confusion if there are multiple people with the same name or if someone later claims they did not agree to the sale. For a vehicle, include the vehicle identification number (VIN), the year, make, model, and color. For other property like boats or equipment, describe it in enough detail that someone reading the document months or years later would know exactly what was sold.
The sale price must be stated clearly. Write out the dollar amount in both numbers and words to prevent disputes over whether the price was $5,000 or $50,000. If the sale included a trade-in, note that separately — for example, "Buyer trades in 2015 Honda Civic valued at $8,000 and pays $12,000 cash for total consideration of $20,000." Both the seller and buyer must sign and date the document. Some people also add the date the buyer takes possession if it differs from the signing date, which can matter for insurance and liability purposes.
Texas does not require the bill of sale to be notarized, though having it notarized adds a layer of proof that both parties actually signed it. A notary public can witness the signatures for a small fee, usually $5 to $15. This is optional but useful if you think there is any chance the other party might later deny they signed.
Handwritten versus printed forms
You can write a bill of sale by hand on plain paper, and it is legally valid in Texas as long as both parties sign it and it contains the key information. Many people do this for informal sales between friends or family. The advantage is simplicity and speed — you do not need to find a form or pay anyone.
Printed forms are available free from the Texas Department of Motor Vehicles website, from office supply stores, and from online legal document services. A printed form can be helpful because it reminds you what information to include and looks more official, which can reduce the chance of disputes later. Some lenders and insurance companies prefer a printed form because it is easier to read and harder to alter. Choose whichever method you are comfortable with; the law does not prefer one over the other.
How the bill of sale connects to vehicle registration and title transfer
When you buy a vehicle in Texas, the seller must sign over the title to you. The title is the state document that proves ownership. The bill of sale is the receipt that shows you paid for it. The Texas Department of Motor Vehicles requires the bill of sale as supporting documentation when you register the vehicle in your name or when you transfer the title from one owner to another.
If you buy a used car from a private seller, bring the signed bill of sale to your local county tax assessor-collector's office along with the signed title, proof of insurance, and your ID. The tax assessor-collector will process the title transfer and register the vehicle to you. If the seller does not have the title (for example, because the lender still holds it), the bill of sale becomes even more important as proof that you own the vehicle and have the right to register it.
For new vehicles from a dealer, the dealer usually handles the paperwork and provides the bill of sale as part of the purchase agreement. For private sales, you are responsible for creating or obtaining the bill of sale and making sure both parties sign it before money changes hands.
What to do with your copy after the sale
The seller should keep a copy of the signed bill of sale for their records. This protects them if the buyer later claims the vehicle was defective or if there is a dispute over the price or terms. The seller may also need it for tax purposes or if the buyer does not register the vehicle and the seller is later contacted by law enforcement or a creditor.
The buyer should keep the original signed bill of sale and bring it to the county tax assessor-collector when registering the vehicle. Keep a copy for your insurance company and your personal records. If you ever sell the vehicle yourself, you may need to show the bill of sale as proof that you own it. Do not throw it away after registration — keep it for at least as long as you own the vehicle.
Common mistakes to avoid when signing a bill of sale
Do not leave the price blank or write it in pencil. Use pen and fill in the amount before both parties sign. Do not sign a bill of sale that the other party has already filled out without reading it first — verify that the vehicle description, price, and terms are correct. Do not assume that a bill of sale signed by only one party is valid; both the buyer and seller must sign for it to be enforceable.
Do not use a bill of sale to hide the true price of a vehicle for tax purposes. The Texas tax assessor-collector uses the stated price to calculate the motor vehicle sales tax owed on registration. Understating the price can result in penalties and back taxes. Do not sign a bill of sale if you are not sure you own the vehicle or have the right to sell it — for example, if a lender still holds the title. The buyer will discover this when they try to register the vehicle, and you could face legal liability.
Frequently Asked Questions
Does Texas require a bill of sale for a used car purchase?
Texas law does not require a bill of sale, but the Texas Department of Motor Vehicles accepts one as proof of ownership when you register the vehicle. Most private sales include a bill of sale because it protects both parties and is needed for the title transfer process at the county tax assessor-collector's office.
Can I use a bill of sale instead of a title to prove I own a vehicle?
No. A bill of sale shows that a sale happened, but the title is the official state document that proves ownership. You need both: the bill of sale to show you purchased the vehicle, and the title in your name to show you legally own it. If the seller has not signed over the title to you, you do not own the vehicle yet.
What if the seller will not sign a bill of sale?
Do not complete the purchase. A seller who refuses to sign a bill of sale is a red flag that they may not own the vehicle, may owe money on it, or may be hiding something. You cannot safely register the vehicle without a signed bill of sale and a signed title from the seller. Walk away from the deal.
Is a notarized bill of sale required in Texas?
No, notarization is not required by law. However, having a notary public witness both signatures adds proof that the document is genuine and can help prevent disputes later. It costs a few dollars and takes a few minutes, and some lenders or insurance companies may prefer it.
Can I write a bill of sale on any piece of paper?
Yes. Texas does not require a specific form or format. You can write a bill of sale by hand on plain paper as long as it includes the seller's name and address, the buyer's name and address, a description of the item, the price, and both signatures with the date. A printed form is not required but can be helpful as a reminder of what to include.
