You'll need to sign the car purchase agreement (or dealer bill of sale), the title, an odometer statement, and sometimes a damage disclosure statement. Vehicle forms: Application for Texas Title (130-U), Application for Motor Vehicle Title, Service and Runner License.Please include a copy of your title to the mobile home or a verified copy of your purchase contract along with your exemption form. Buying a car without a title is a risk, and will require extra effort to get a valid title before you can register it.
