01Signing over the title
Sign the title on the seller line (line 1) and hand it to the buyer, who submits it to the DMV. Record the odometer reading and sale details as the title directs. If the title is lost, you must first get a replacement using form REG 227. The DMV pages we reviewed do not call for notarization of a seller's signature on an ordinary title.
Official source ↗02License plates
In general, license plates stay with the vehicle they were issued to, so standard plates normally stay on the car. Personalized, special recognition and special interest plates are different: they can be moved to another vehicle if the owner asks and pays the fees. If you have those, remove them before the buyer takes the car.
Official source ↗03Telling the state you sold it
File a Notice of Transfer and Release of Liability (NRL, form REG 138) within 5 calendar days of the sale. You need the plate number, last five digits of the VIN, the buyer's name and address, the odometer reading and the sale date. Once the DMV records it, parking tickets, traffic violations and civil claims after the sale shift to the buyer. Save your online confirmation or a photocopy of the paper form.
