Car Sale Contract in California
Everything you need to know about writing a valid, enforceable car sale contract for a private vehicle transaction in California.
Bill of Sale vs. Sale Contract in California
In California, a bill of sale (REG 135) is the standard document for private vehicle sales. A separate written contract adds legal clarity but is not separately required by law.
CA DMV accepts REG 135 as the official bill of sale. Courts recognize any written contract meeting basic contract law requirements.
Required Provisions
California courts apply standard contract law. All six provisions must be present for an enforceable agreement.
Recommended Contract Clauses
Include all four clauses verbatim to maximize seller protection under California law.
"This vehicle is sold as-is, where-is, with all faults. No warranties express or implied."
"Seller certifies odometer reads [X] miles and to the best of seller's knowledge reflects actual mileage."
"Buyer acknowledges receipt and inspection of the vehicle prior to purchase."
"This agreement constitutes the entire agreement between the parties."
Dealer vs. Private Sale Contracts
California dealers must use the Retail Installment Sales Contract (RISC) or equivalent. Private sellers use a simple written agreement or REG 135.
Licensed dealers are subject to the California Automobile Sales Finance Act and must use approved contract forms.
Notarization Requirements
California does not require notarization of a private car sale contract. Notarization adds evidentiary weight but is not legally required.
