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 ↗02Bill of sale
A separate bill of sale is not required when the title is properly signed, but both sides may want to complete one and keep a copy. The DMV publishes an optional Bill of Sale (REG 135), and any bill of sale that identifies the vehicle is acceptable. It does not need to be notarized or witnessed.
Official source ↗03License 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 ↗04Telling 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.
Official source ↗05Smog, emissions or safety inspection
The seller must give the buyer a valid Smog Check certification. For a private sale it must have passed within the last 90 days, and you should hand the buyer a copy of the vehicle inspection report. Exempt: gas, hybrid or alternative-fuel vehicles four model years old or newer (the buyer pays a smog transfer fee), gas 1975 and older, diesel 1997 and older, electric vehicles, and transfers between immediate family.
Official source ↗06If you still owe money on the car
If a bank or lender is listed as legal owner, the lienholder holds the title, so pay off the loan first and get the title or a Lien Satisfied/Title Holder Release (REG 166) from the lender. The DMV also has a tool to find a lender that has closed or merged.
Official source ↗07Odometer disclosure
Odometer disclosure is required on transfer for vehicles less than 20 model years old (rule in effect for transfers since January 1, 2021). Older vehicles are exempt from the written disclosure, though the DMV encourages disclosure anyway. Photocopied disclosures are not acceptable on the original.

Follow the current instructions from the California DMV for your vehicle, especially for lost titles, several owners, out-of-state buyers or a car that is not fully paid off.
