What a Texas vehicle bill of sale is and why you need one

A vehicle bill of sale is a written record that documents the transfer of ownership of a car, truck, motorcycle, or other motor vehicle from one person to another. In Texas, it serves as proof that a sale took place, who bought it, who sold it, and for how much. The state does not require a bill of sale to register a vehicle, but the Texas Department of Motor Vehicles recognizes it as evidence of ownership transfer, and most lenders, insurance companies, and title services will ask for one.

The bill of sale protects both the buyer and seller. For the buyer, it shows they purchased the vehicle legitimately and establishes their claim to ownership. For the seller, it proves they no longer own the vehicle and removes their liability once the sale is complete. Without a bill of sale, disputes over who owns the vehicle or who is responsible for it can become difficult and expensive to resolve.

Key Takeaways

  • Texas does not legally require a bill of sale, but the DMV recognizes it as proof of ownership transfer and most title companies will not process a transfer without one.
  • A bill of sale must include the vehicle identification number (VIN), the sale price, the date of sale, and the signatures of both buyer and seller.
  • You can use the Texas DMV Form 14-10 (Affidavit of Motor Vehicle Transfer and Reassignment of Title), a template from an online source, or write your own as long as it contains all required information.
  • The buyer should keep the bill of sale with their title documents and insurance records; the seller should keep a copy for their records.
  • A bill of sale does not transfer the title itself — the buyer must still submit the title and bill of sale to the DMV to register the vehicle in their name.

What information must be included on a Texas bill of sale

A valid Texas bill of sale must contain specific details about the vehicle and the transaction. The vehicle identification number (VIN) is the most important piece of information — it uniquely identifies the vehicle and prevents confusion if the buyer or seller owns multiple vehicles. The bill of sale must also list the year, make, and model of the vehicle, the odometer reading at the time of sale, and the sale price in dollars.

Both the buyer and seller must sign and print their names on the bill of sale. The seller should include their printed name, signature, and the date. The buyer should do the same. Some transactions also benefit from including the buyer's and seller's addresses and phone numbers, though Texas law does not strictly require them. If the vehicle has a lien (a loan against it), the name of the lienholder should be noted as well.

The date of the sale should be written clearly. This date matters because it establishes when ownership transferred and can affect insurance coverage and liability. If the sale happened on one date but the bill of sale was signed later, use the actual sale date, not the signing date.

Using the official Texas DMV form versus writing your own

The Texas Department of Motor Vehicles publishes Form 14-10, titled "Affidavit of Motor Vehicle Transfer and Reassignment of Title." This form is designed specifically for Texas vehicle transfers and is widely accepted by title companies, lenders, and the DMV itself. You can read it from the DMV website at txdmv.gov at no cost. Using the official form removes guesswork about what information to include and is often the fastest route to a smooth title transfer.

You are not required to use Form 14-10. Texas law allows you to write your own bill of sale as long as it includes all the required information: VIN, year, make, model, odometer reading, sale price, date, and signatures of both parties. Many people use templates from online sources or write a straightforward document on plain paper. The key is that the document must be clear, legible, and contain all the facts about the transaction.

If you use your own form, keep it straightforward and factual. Avoid vague language like "sold as-is" or "no warranty" — those statements do not belong on a bill of sale and can create confusion. The bill of sale is a record of the transaction, not a warranty document or service agreement.

How to handle the sale price and payment method

The bill of sale should state the actual amount paid for the vehicle, whether that is cash, a check, a wire transfer, or another form of payment. Write out the dollar amount in numbers (for example, $8,500) and, if you prefer, also write it in words. Do not leave the price blank or write "paid in full" without a number — title companies need the specific amount to process the transfer.

The bill of sale does not need to describe the payment method itself (cash, check, etc.). It only needs to record that a price was agreed upon and paid. If the buyer is financing the vehicle through a lender, the bill of sale still shows the full purchase price, not just the down payment. The lender's involvement is separate from the bill of sale and will be handled through the title transfer process.

If you are selling the vehicle for less than its market value — for example, to a family member or as a gift with a nominal price — still record the actual amount exchanged. Underreporting the price on a bill of sale can raise red flags with the DMV and title companies and may delay the transfer.

Signing and witnessing the bill of sale

Both the buyer and seller must sign the bill of sale in front of each other or at least acknowledge their signatures. Texas does not require the signatures to be notarized for a basic bill of sale, though some people choose to have it notarized for extra protection. A notarized bill of sale carries more legal weight if a dispute arises later.

Witnesses are not required by Texas law, but having a neutral third party sign as a witness can be helpful if questions arise about whether both parties actually agreed to the sale. If you include a witness, they should print their name, sign, and write the date. The witness does not need to be notarized either, but their presence adds credibility to the document.

Make sure both parties sign in ink, not digitally, unless you are using an electronic signature service that both parties trust. Keep the original signed bill of sale — photocopies or digital scans may not be accepted by the DMV or title company.

What happens after the bill of sale is signed

Once the bill of sale is signed, the buyer should keep it in a safe place with their other vehicle documents. The buyer will need the bill of sale, the title certificate, and proof of insurance to register the vehicle with the Texas DMV. The registration process is separate from the bill of sale — the bill of sale is evidence of the transfer, but the title transfer itself happens when the buyer submits the title and bill of sale to the DMV.

The seller should also keep a copy of the signed bill of sale for their records. This protects the seller by proving they no longer own the vehicle and are not responsible for it after the sale date. If the vehicle is involved in an accident, traffic violation, or other incident after the sale, the seller can show the bill of sale to prove the vehicle was no longer theirs.

The buyer typically has 30 days from the date of purchase to register the vehicle with the DMV. During that time, the buyer should carry the bill of sale and proof of insurance. After registration, the buyer will receive a new title certificate in their name.

Common mistakes to avoid when writing a bill of sale

One frequent error is leaving out the VIN or writing it incorrectly. Double-check the VIN against the vehicle's title certificate or the dashboard placard — a wrong VIN can delay or prevent the title transfer. Another mistake is not signing the document or having only one party sign. Both buyer and seller must sign for the bill of sale to be valid.

Do not post-date or back-date the bill of sale. Use the actual date the sale occurred. Changing the date can raise suspicion and may be treated as fraud by the DMV. Similarly, do not leave the price blank or write "negotiable" or "to be determined" — the price must be a specific dollar amount at the time of signing.

Avoid adding conditions or warranties to the bill of sale, such as "buyer agrees to fix the engine" or "seller guarantees no mechanical problems." Those belong in a separate purchase agreement, not on the bill of sale. The bill of sale is a record of the transfer, not a contract about the vehicle's condition.

Frequently Asked Questions

Do I have to use the official Texas DMV form?

No. Texas law does not require you to use Form 14-10, but it is widely accepted and removes the risk of missing required information. If you write your own bill of sale, make sure it includes the VIN, year, make, model, odometer reading, sale price, date, and signatures of both parties. Many title companies prefer the official form because it is standardized.

What if I sell a vehicle with an outstanding loan on it?

The bill of sale should note the lienholder's name and the fact that the vehicle has a lien. The seller is responsible for paying off the loan before the title can transfer to the buyer's name. The bill of sale does not clear the lien — that happens through the lender when the loan is paid in full. The buyer should not take possession of the vehicle until the lien is removed from the title.

Can I use a bill of sale instead of a title certificate?

No. A bill of sale is proof that a sale occurred, but it does not transfer ownership. The title certificate is the legal document that proves ownership. The buyer must submit both the bill of sale and the title certificate to the DMV to register the vehicle in their name. Without the title, the transfer cannot be completed.

Is a notarized bill of sale required in Texas?

No, notarization is not required by Texas law. However, having the bill of sale notarized adds an extra layer of legal protection and may be useful if a dispute arises later. Some lenders or title companies may request a notarized bill of sale, so it is worth asking before you sign.

What should I do if I lost the bill of sale after the sale?

If you are the buyer, contact the seller and ask for a copy. If the seller will not provide one, you can still register the vehicle using the title certificate alone, though some title companies may ask for the bill of sale. If you are the seller and lost your copy, keep the title certificate showing the transfer to the new owner. The DMV records will show the transfer date and new owner's name.
