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

A bill of sale for a trailer is a written record that documents the transfer of ownership from one person to another. In Texas, it serves as proof that you bought or sold a trailer and establishes who owns it on a specific date. The state does not require a bill of sale by law for all trailers, but you will need one if you want to register the trailer with the Texas Department of Motor Vehicles or if you are financing the purchase through a lender.

The bill of sale protects both the buyer and seller. For the buyer, it proves you paid for the trailer and own it. For the seller, it shows you transferred ownership and are no longer responsible for the trailer. Without a bill of sale, disputes about who owns the trailer or when the sale happened become much harder to resolve.

Texas does not have a single official bill of sale form that you must use. You can write your own, use a template, or purchase a pre-printed form from an office supply store or online. What matters is that the document includes the required information and is signed by both parties.

Key Takeaways

  • A bill of sale must include the names and addresses of both buyer and seller, a description of the trailer, the sale price, and the date of the sale.
  • Both the buyer and seller must sign the bill of sale in front of a notary public if you plan to register the trailer with the state.
  • Texas does not require a specific form, but the document must be clear enough to prove ownership transfer if a dispute arises.
  • Keep a copy of the signed bill of sale for your records, and provide the original or a certified copy to the buyer or to the DMV if registration is needed.

What information must go on a Texas trailer bill of sale

The bill of sale must clearly identify both parties to the transaction. Write the full legal name and current address of the seller and the full legal name and current address of the buyer. If either party is a business, use the business name and the address where the business is located.

Describe the trailer in enough detail that someone reading the bill of sale could identify which specific trailer you are talking about. Include the year, make, model, and color. If the trailer has a Vehicle Identification Number (VIN), write that down. If it does not have a VIN, describe any unique features—such as the size, number of axles, or condition—that set it apart from other similar trailers.

State the sale price in dollars. Write out the amount in both numbers and words to avoid confusion—for example, "One Thousand Five Hundred Dollars ($1,500.00)." If the trailer is being given as a gift or transferred for no money, write "No consideration" or "Gift" in the price field.

Include the date the sale took place. This is the date both parties signed the document, not the date you agreed to buy it or the date you picked it up. Write the date in a clear format, such as "January 15, 2025."

Whether you need a notary and when to get one

If you are registering the trailer with the Texas Department of Motor Vehicles, the bill of sale must be notarized. This means both the buyer and seller must sign the document in front of a notary public, who will then sign and stamp it to confirm they witnessed the signatures.

You can find a notary public at most banks, credit unions, law offices, and UPS stores. Some charge a small fee, usually between $5 and $15 per signature. Call ahead to confirm they are available and ask what documents they need you to bring. You will need to bring a photo ID and the unsigned bill of sale.

If you are not registering the trailer with the state—for example, if you are selling a trailer that will not be used on public roads—you may not need a notary. However, having the document notarized adds legal weight to it and is a good practice even when it is not required.

How to sign the bill of sale correctly

Both the buyer and the seller must sign the bill of sale. If a notary is involved, you must both sign in front of the notary at the same time or at separate appointments, depending on what the notary allows. The notary will watch you sign, confirm your identity using your photo ID, and then sign and stamp the document themselves.

If you are not using a notary, both parties should still sign the document in the presence of each other if possible. This makes it harder for either party to later claim they did not agree to the sale. Each person should sign their full legal name, not a nickname or initials.

Some bill of sale forms include a line for a witness signature. A witness is a third person who sees both parties sign. Witnesses are not required in Texas, but adding one can strengthen the document if a dispute arises later.

What to do with the signed bill of sale

After both parties have signed, make at least two copies of the bill of sale—one for the buyer and one for the seller. If the document was notarized, ask the notary for certified copies, which have the notary's seal and signature on them. Certified copies carry more weight in legal situations than regular photocopies.

If you are the buyer and you plan to register the trailer with the Texas Department of Motor Vehicles, you will need to submit the original signed bill of sale or a certified copy along with your registration process. The DMV will use it to confirm ownership and issue a title in your name.

If you are the seller, keep a copy for your records. This protects you if the buyer later claims you did not transfer ownership or if there is a dispute about the sale price or condition of the trailer. Store it in a safe place, such as a filing cabinet or safe deposit box.

Registering the trailer after the sale

Once you have a signed bill of sale, the buyer can register the trailer with the Texas Department of Motor Vehicles. Registration is done through your county tax assessor-collector's office, not directly through the DMV. You will need to bring the bill of sale, proof of ownership (such as the previous title), proof of insurance, and a completed process for Texas Title and/or Registration form (Form 130-U).

The tax assessor-collector will charge a registration fee based on the trailer's value and weight. Fees vary by county, so call your local office to find out the exact cost. Registration is valid for one or two years, depending on the type of trailer and what you choose when you register.

If the trailer does not have a title from a previous owner—for example, if it is a homemade or very old trailer—you may need to explore for a new title through a different process. Contact your county tax assessor-collector to ask what documents they need.

Common mistakes to avoid when writing a bill of sale

Do not leave any required fields blank. If a field does not explore—for example, if there is no VIN—write "N/A" or "Not applicable" instead of leaving it empty. Blank spaces can make the document look incomplete and may cause the DMV to reject it.

Do not use informal language or abbreviations that might be unclear. Write out the full names of both parties, spell out the trailer's make and model, and use standard date formats. A bill of sale is a legal document, and clarity matters if it ever needs to be used in court.

Do not sign the document before both parties have agreed on all the terms. Once it is signed, it becomes a binding record of the sale. If you discover an error after signing, both parties should initial the correction or create a new bill of sale with the correct information.

Do not forget to keep a copy. Many people sign a bill of sale and then lose track of it. Store your copy somewhere safe and accessible, so you can find it if you need to prove ownership or resolve a dispute.

Frequently Asked Questions

Can I write my own bill of sale or do I have to use an official form?

Texas does not require a specific official form. You can write your own bill of sale as long as it includes the seller's name and address, buyer's name and address, trailer description, sale price, and date. Many people use templates from office supply stores or online sources, which is also acceptable.

What if the trailer does not have a VIN?

Write "No VIN" or "Not applicable" on the bill of sale and describe the trailer in as much detail as you can instead. Include the year, make, model, color, size, number of axles, and any other features that would help someone identify it. This is especially common with older or homemade trailers.

Do both the buyer and seller have to be present when the bill of sale is notarized?

Most notaries require both parties to be present at the same time, but some allow them to sign at separate appointments. Call the notary ahead of time to ask about their policy. If you cannot both be there, you may be able to have one person sign and then have the other sign later, though this is less common.

What if I lost my copy of the bill of sale?

If you have the notarized original, the notary may be able to provide you with a certified copy for a small fee. If you do not have the original, contact the other party and ask them to provide a copy. If neither of you has it, you may need to create a new bill of sale and have it notarized again, though this is unusual.

Do I need a bill of sale if I am giving the trailer away as a gift?

If you plan to register the trailer with the Texas Department of Motor Vehicles, you will need a bill of sale even for a gift. Write "Gift" or "No consideration" in the price field instead of a dollar amount. The notarization and registration process remain the same.
