An as-is bill of sale in California is a signed record of a private sale in which the buyer accepts the item in its current condition and the seller disclaims any implied warranties about it. California Commercial Code Section 2316 lets a seller use the words “as is” or “with all faults” to cut off those warranties, and the document itself locks in the price, the parties, and the date the item changed hands. For most Californians, the item is a used vehicle, and the bill of sale is one piece of a slightly larger paperwork job.
What “As Is” Actually Does Under California Law
Section 2316 of the Commercial Code allows a seller to exclude implied warranties by using language a reasonable person would read as “no guarantees.” “As is” does that automatically. So does “with all faults.”1California Legislative Information. California Code COM 2316 – Exclusion or Modification of Warranties
Two implied warranties get stripped away. The warranty of merchantability is the unspoken promise that an item works for its ordinary purpose. The warranty of fitness is the unspoken promise that it suits a specific use the buyer told the seller about. An “as is” clause wipes out both. The statute goes further: if the buyer had the chance to inspect the item and either did so or refused, there is no implied warranty covering defects that a reasonable inspection would have caught.1California Legislative Information. California Code COM 2316 – Exclusion or Modification of Warranties
California’s stronger consumer warranty law, the Song-Beverly Act, only reaches goods sold at retail. Private sales between individuals sit outside it, which is why an “as is” disclaimer between two people carries real weight.
What to Include in the Document
California doesn’t require a specific format. The DMV publishes a bill of sale form, the REG 135, and the Vehicle/Vessel Transfer and Reassignment Form (REG 262) contains a section that also works as a bill of sale.2California Department of Motor Vehicles. Vehicle Industry Registration Procedures Manual – Bill of Sale Whether you use one of those or draft your own, the document should carry:
- Full legal names, addresses, and signatures of the buyer and seller.
- A clear description of the item. For a vehicle, that means make, model, year, VIN, and license plate number.
- The odometer reading, when the vehicle falls within the reporting thresholds below.
- The exact sale price and the date of the transaction.
- A prominent “as is” clause stating the item is sold in its present condition with no warranties of any kind. Fine print invites arguments; plain, visible language avoids them.
Both parties should walk away with a signed copy. The buyer needs it for registration and use tax; the seller needs it as proof of what was sold and on what terms.
Vehicle Paperwork Beyond the Bill of Sale
A bill of sale and a title do different jobs. The bill of sale records the transaction. The title, issued by the state, proves legal ownership, and signing it over is what actually transfers a vehicle in California. The DMV requires a signed title for registration and only requires a bill of sale in specific situations, such as when the seller isn’t the person named on the title.3California Department of Motor Vehicles. Registration for a Vehicle Purchased from a Private Party
Two deadlines matter after the sale. Any change in ownership must be reported to the DMV within 10 days and the title must be updated. The seller must submit a Notice of Transfer and Release of Liability within 5 days. Miss that NRL and the seller can be chased for parking tickets and liability tied to a car they no longer own.4California Department of Motor Vehicles. Title Transfers and Changes
Smog Certification Is Not Waivable
Selling “as is” does not release the seller from California’s smog obligation. Before a private-party sale closes, the seller must provide a valid smog check, and the inspection report has to be current, meaning the vehicle passed within the prior 90 days.5California Bureau of Automotive Repair. Smog Check: When You Need One and What’s Required
This one catches sellers by surprise. The “as is” clause disclaims warranties between buyer and seller. Smog is a regulatory duty owed to the state, and no private agreement can disclaim it.
Some vehicles are exempt at change of ownership:
- Gasoline, hybrid, and alternative-fuel vehicles four model years old or newer. The seller pays a smog transfer fee to the DMV instead.
- Gasoline, hybrid, and alternative-fuel vehicles from model year 1975 or older.
- Diesel vehicles from model year 1997 or older, or those with a gross vehicle weight rating above 14,000 pounds.
- Electric vehicles and motorcycles, which are always exempt.
Transfers between immediate family members also skip the smog requirement.5California Bureau of Automotive Repair. Smog Check: When You Need One and What’s Required
Odometer Disclosure Rules
California requires an odometer reading on the title or REG 262 for vehicles that are nine model years old or newer. Subtract 10 from the current calendar year to find the cutoff; anything older is exempt. Also exempt: commercial vehicles with a gross vehicle weight over 16,000 pounds, motorcycles beyond the age threshold, and low-speed vehicles.6California Department of Motor Vehicles. Chapter 5 Odometer Mileage Reporting
Federal law layers on top. For model year 2011 and newer vehicles, odometer disclosure is required for the first 20 years of the vehicle’s life. Model year 2010 and older vehicles remain exempt federally.7NHTSA. Consumer Alert: Changes to Odometer Disclosure Requirements Vehicles with a gross vehicle weight rating over 16,000 pounds are also exempt from the federal rule.8eCFR. 49 CFR 580.17 – Exemptions Misstating the number is a federal offense, and no “as is” clause changes that.
Where the “As Is” Clause Stops Working
The disclaimer is powerful, but it has a ceiling. California Civil Code Section 1668 voids any contract that tries to exempt someone from responsibility for their own fraud or willful injury.9California Legislative Information. California Civil Code 1668 A seller cannot contract out of fraud liability.
Civil Code Section 1710 defines deceit to include stating something as fact you don’t believe, asserting a fact without reasonable grounds to believe it, suppressing a fact you’re obligated to disclose, or making a promise you never intend to keep.10California Legislative Information. California Civil Code 1710 The suppression prong is the one sellers stumble into most often. If a buyer asks whether the transmission has problems and the seller stays quiet knowing it’s failing, that silence can amount to fraud even with “as is” in bold across the top of the bill of sale.
Puffery is different. A seller who says “this car runs great” while genuinely believing it isn’t liable when the engine fails next week. Vague, subjective claims like “it’s a solid truck” aren’t actionable. But “the engine was rebuilt last year,” said when it wasn’t, is misrepresentation, and the “as is” clause offers no defense.
Use Tax the Buyer Will Owe
A California buyer owes use tax when registering a private-party vehicle at the DMV. The rate matches the sales tax rate for the buyer’s registration address and varies by county. It applies to the total purchase price, including loans assumed, trade-ins, or any other consideration exchanged.11California Department of Tax and Fee Administration. Tax Guide for Purchasers of Vehicles
The price written on the bill of sale is the number the DMV and the California Department of Tax and Fee Administration use. If it looks suspiciously low against the vehicle’s market value, the state can assess tax on fair market value instead. Title transfer fees and registration fees are separate.
What a Buyer Should Do Before Signing
Buying “as is” means the moment you sign, every problem the item has is yours. Your inspection beforehand is the real protection.
For a vehicle, an independent pre-purchase inspection typically runs $100 to $200 and can surface problems worth thousands. Pull the vehicle history using the VIN to check for accident reports, salvage or flood titles, and odometer discrepancies. Ask the seller direct questions about the car’s condition and history. If the seller makes a specific factual claim you care about, write it into the bill of sale. That written record is what turns a broken promise into a documented misrepresentation if the claim later proves false.
