You sign a car title in Texas on the front of the title, specifically in the section labeled "Assignment of Title by Owner(s)" (or similar wording). The seller must sign exactly as their name appears printed on the title. If there are multiple owners listed, all must typically sign. The buyer's information is filled out in this same section at the time of sale.
Getting this right is critical because an error can lead to the Texas Department of Motor Vehicles (TxDMV) rejecting the title transfer, causing significant delays for the new owner. The most important step, often required in Texas, is to have the seller's signature notarized. A notary public verifies the seller's identity to prevent fraud. While some county tax assessor-collector offices may provide notary services, it's best to arrange this beforehand.
Beyond the signature, correctly completing the entire assignment area is essential. This includes the date of sale, the sales price, and the vehicle's odometer reading. The odometer reading must be accurate and the appropriate box (e.g., "Actual Mileage," "Exceeds Mechanical Limits") must be checked. Both parties should keep a bill of sale as an additional record. The buyer then takes the fully signed and notarized title, along with other required documents, to their county tax office to complete the transfer, pay fees, and get a new title and registration in their name.
| Key Field on Texas Title | What to Do | Why It Matters |
|---|---|---|
| Seller(s) Signature(s) | Sign exactly as printed. All listed owners must sign. | Invalidates the title if mismatched or missing a signature. |
| Notary Acknowledgment | Seller's signature must be notarized. | A legal requirement in Texas to prevent title fraud. |
| Buyer(s) Information | Print full name(s) and complete address accurately. | Ensures the new title and tax bill are sent to the correct person/address. |
| Date of Sale | Record the exact date the vehicle and payment exchange hands. | Officially documents the transfer of ownership. |
| Sales Price | State the actual amount paid for the vehicle. | Used to calculate the standard presumptive value tax if applicable. |
| Odometer Reading | Record the mileage and check the correct disclosure statement. | Federal law requires accurate mileage disclosure during a sale. |

Front and center, literally. Look for the "Assignment of Title" box on the front page. You, the seller, sign there exactly how your name is shown. Don't forget the odometer reading and sales price—they need those details too. The big one in Texas: you'll likely need a notary to witness your signature. I learned that the hard way; had to track the guy down a week later. Just get it done at the sale.

As a buyer, my main concern is making sure the seller does their part correctly so I don't get stuck. I always meet at a bank or a UPS Store with a notary. I watch the seller sign the title in the assignment section, and the notary stamps it right then. I double-check that the odometer is filled out and that the price is written down. A clean, notarized title is my ticket to a smooth visit at the tax office. Anything less is a red flag.
