What's included in the California Bill of Sale
California Bill of Sale Requirements
California requires a bill of sale (REG 135) when transferring a vehicle between private parties. The California DMV requires the Notice of Transfer and Release of Liability (NRL) to be filed by the seller within 5 days of the sale at dmv.ca.gov. This is critical in California because it releases the seller from liability for parking tickets, accidents, and other incidents. The bill of sale must include the vehicle's VIN, license plate number, odometer reading, sale price, and signatures of both parties. California does not require notarization for a vehicle bill of sale. The buyer has 10 days to transfer the title and register the vehicle with the CA DMV.
