Title Transfer
Jefferson County Title Transfers Need Form 130-U and a Signed Title
Four things make a clean title transfer in Jefferson County: the Texas title application (Form 130-U) signed by both buyer and seller, the title itself signed by both parties, proof of liability insurance in the buyer's name, and a current, unexpired ID or driver license. The buyer has 30 days from the sale date to apply, and missing that window adds a penalty to the bill.
Any of the three offices can handle it: Beaumont, Nederland (Mid-County), or Port Arthur. Before you head over, think about whether your sale has a wrinkle: a lien release, a gift, an inherited vehicle, a power of attorney, an out-of-state title, or a lost title. Each of those usually needs an extra form, and discovering that at the counter turns one trip into two.
If you're the seller, file a vehicle transfer notification with TxDMV so you're not on the hook for tickets or tolls the new owner racks up before they retitle. That one step keeps a sold car from following you around.
