California REG 135 — Bill of Sale
REG 135 is the California DMV's official bill of sale form. It is not legally required — a privately drafted document with the same fields is also accepted — but DMV clerks process REG 135 without question. Sellers should also file REG 138 (Notice of Transfer and Release of Liability) within 5 days of the sale.
