California DMV does not have an official bill of sale form, but you can create your own or use a template. The important forms are the title (REG 227 for duplicate title) and the Release of Liability filed online at dmv.ca.gov.
Required Clauses in a California Vehicle Purchase Agreement
Every vehicle purchase agreement in California should include the following elements to be legally complete and enforceable:
- 1Buyer and seller full legal names and addresses
- 2Vehicle identification number (VIN)
- 3Year, make, model, and color of the vehicle
- 4Odometer reading at time of sale
- 5Sale price in dollars
- 6Date of sale
- 7Seller's signature (notarization not required)
- 8Buyer's signature (notarization not required)
- 9Statement of any known defects or 'AS IS' language
Omitting any of these elements can create legal ambiguity and make the agreement harder to enforce if a dispute arises.
Seller Disclosures Required in California
Private sellers in California have a legal obligation to disclose known material defects that affect the vehicle's safety, value, or operation. Failing to disclose known issues can expose the seller to fraud or misrepresentation claims even in an as-is sale.
- Known mechanical defects that affect safe operation
- Prior salvage or rebuilt title status
- Flood or fire damage history
- Known odometer discrepancy (if odometer is inaccurate)
- Smog certificate status
As-Is Sales in California: What Sellers Must Know
California private party sales are sold 'as is' by default. Dealers (not private parties) are required to provide buyer guides. For private sales, include 'Sold As Is, No Warranty' in the agreement to protect yourself from post-sale claims.
Private sellers in California are not required to provide any warranty. Dealer sales include implied warranties unless specifically disclaimed with a Buyer's Guide.
Sample As-Is Language
THIS VEHICLE IS SOLD "AS IS — NO WARRANTY." The seller makes no representations or warranties, express or implied, regarding the condition, merchantability, or fitness for a particular purpose of the vehicle described herein. The buyer acknowledges that they have had the opportunity to inspect the vehicle prior to purchase and accepts the vehicle in its current condition.

Buyer Protections: Lemon Law and Warranty Coverage in California
California Lemon Law: Does not apply to private party sales
California's lemon law (Song-Beverly Consumer Warranty Act) applies only to NEW vehicles and used vehicles purchased from a dealer. Private party used car sales are NOT covered by the California lemon law.
For private party used car purchases in California, your primary legal protection is accurate seller disclosure. If a seller knowingly conceals a material defect, you may have a fraud or misrepresentation claim — but this requires proving the seller had knowledge of the defect at the time of sale.
Deposits and Earnest Money in California
California has no specific statute governing vehicle purchase deposits in private sales. A written deposit agreement specifying refund conditions is strongly recommended. Deposits are typically non-refundable if the buyer backs out.
Cancellation Rights: Is There a Cooling-Off Period in California?
Cooling-Off Period: Not available for private vehicle sales
California's cooling-off (right to cancel) law does NOT apply to vehicle sales. Once a private sale is complete and the title is signed, it is final. There is no legal right to return a privately purchased vehicle.
Because private vehicle sales are generally final in California, buyers should complete all due diligence — vehicle history report, independent mechanical inspection, title verification — before signing any purchase agreement or handing over payment.
