Vehicle bill of sale requirements in California

In California, ownership transfers through the California DMV using the signed title (and REG 262 verification of vehicle for some sales). A bill of sale is not legally required, but both buyer and seller benefit from having one as proof of the sale price, date, and terms.

California does not require notarization for a vehicle bill of sale. Record the sale price, the vehicle's VIN, the odometer reading, and an 'as-is' statement so there is no confusion later.

Keep your copy with the title paperwork and any smog certificate until the DMV completes the transfer.
