Williamson County Title Transfers Need the Tax Office Paper Trail
A private vehicle sale in Williamson County needs clean paper on both sides. The county title page separates seller steps from buyer steps, including the signed title, Form 130-U, valid ID, and proof of insurance.
TxDMV says the buyer must title the vehicle within 30 days from the sale date. It also recommends a seller transfer notice, which can help if tolls or tickets appear later.
Before going to the Tax Office, look for lien releases, gifts, powers of attorney, out-of-state titles, bonded titles, and inspection records. Those details are what turn one trip into two.
