- Federal law, Title 49 of the Code of Federal Regulations (CFR), Part 580, requires a written odometer disclosure on almost every private sale. The only exceptions are a 2010-or-earlier model year car already past 10 years old, or a 2011-or-newer model year car that has reached 20 years old.
- The Federal Trade Commission (FTC)’s Used Car Rule and its Buyers Guide window sticker apply only to dealers who sell more than five used vehicles a year, not to someone selling their own car.
- California’s release-of-liability filing, the Notice of Transfer and Release of Liability (NRL) on form REG 138, has to reach the state’s Department of Motor Vehicles (DMV) within 5 calendar days of the sale. Miss that window and the seller stays tied to the buyer’s tickets.
- California separately gives the buyer 10 days after the purchase to complete the title transfer, a different clock than the seller’s 5-day filing deadline.
A private seller stops being legally tied to a car by filing their state’s release-of-liability notice within days of the sale, not by signing the title. A signed title alone does not update the state’s ownership record or remove the seller’s name from citations the car picks up later.

David Ferreira sold his 2015 Honda Accord for $8,600 on a Saturday in June, in a Sacramento parking lot, cash from a stranger he met through a classifieds app. He signed the title over and drove home in his wife’s car. He never filed California’s release-of-liability form. Three months later, two toll-crossing citations for a bridge he had not driven since 2019, $137 combined, showed up in his mailbox, addressed to him.
The odometer disclosure rule
Federal law, 49 U.S.C. § 32705 and its implementing regulation at 49 CFR Part 580, requires a written odometer disclosure at the moment a vehicle changes hands. The National Highway Traffic Safety Administration (NHTSA) administers the rule. Most states build the disclosure into the title’s transfer section, so signing the title usually makes the disclosure too.
Not every sale needs one. NHTSA’s exemption rule depends on the car’s model year. A vehicle from model year 2010 or earlier is exempt once it is 10 years past that model year. A vehicle from model year 2011 or newer does not become exempt until it turns 20 years old, a threshold NHTSA finalized in 2019, effective January 1, 2021, extending disclosure to millions more vehicles. David’s 2015 Accord is nowhere near either cutoff. It will not be exempt until 2035, so he still had to give the buyer an accurate mileage statement, apart from anything about the car’s condition.
What “as-is” actually waives
Many private sellers write “as-is, no warranty” on the bill of sale and assume the phrase closes the door on every future complaint. It closes fewer doors than most sellers think. The FTC’s Used Car Rule, the regulation behind the familiar window-sticker Buyers Guide, applies only to dealers who sell or offer for sale more than five used vehicles in a 12-month period. Someone selling their own car once is not a “dealer” under that rule and never has to post a Buyers Guide.
That gap in dealer regulation does not create a blanket shield for private sellers, though. “As-is” generally waives a claim that the car has to keep working a particular way, so ordinary wear and defects the seller never knew about are usually covered. It typically does not waive liability for misrepresenting a known problem, such as claiming a transmission was just rebuilt when it was not, or hiding a title brand. State fraud law, not “as-is” language, governs that, and it varies enough that a seller should not assume the phrase covers everything.
The release-of-liability filing

This is the piece that determines whether the state keeps associating a seller’s name with a car after the sale, and it is not federal at all. Every state runs its own version, under its own name and deadline, so a seller has to check their own state’s motor vehicle agency rather than assume a nationwide rule applies.
California’s version is a well-documented example of how the mechanic works. Under California Vehicle Code § 5900, a seller has to get the Notice of Transfer and Release of Liability to the Department of Motor Vehicles within 5 calendar days of the sale. Once the DMV has it, the state treats any parking or moving violation, or civil claim, tied to the car after that date as the buyer’s problem. That holds regardless of whether the buyer ever finishes their own paperwork. That is what caught David. A signed title sitting in a drawer does not update a state database on its own. His name stayed attached to the car until the day he filed the notice, three months and two toll citations later.
The title-transfer clock
A private sale runs on two separate clocks that belong to two different people, and mixing them up is the most common paperwork mistake in a private sale. The seller’s clock is the release-of-liability filing above, measured in days from the sale. California gives the buyer a separate clock: 10 days after the purchase to complete the title transfer on their end.
A buyer who drives around for weeks meaning to get to the Department of Motor Vehicles eventually is burning through that 10-day window with every day the car sits unregistered. The seller cannot force the buyer to hit that deadline. What the seller can control is their own filing, and filing it early removes the seller from the picture regardless of what the buyer does next. A seller who has made the disclosure and filed the release of liability has done everything the law asks of them.
| Situation | Does “as-is” cover it? |
|---|---|
| The transmission fails a week later from ordinary wear | Yes. No implied repair promise survives an as-is sale. |
| The seller said the transmission was just rebuilt, and it was not | No. Misrepresenting a known fact is not covered by as-is language. |
| The mileage stated on the odometer disclosure | No. Federal odometer disclosure law applies regardless of as-is terms. |
| A pre-existing defect the seller genuinely never knew about | Yes. As-is protects against defects the seller had no knowledge of. |
| A branded or salvage title the seller failed to disclose | No. Concealing a known title brand is treated as misrepresentation. |
Frequently asked questions
Do I have to give the buyer a written odometer disclosure if I’m just selling my own car privately? Yes, unless the car is old enough to be exempt. Federal law requires a written odometer statement on almost every private sale. The exceptions are a 2010-or-earlier model year already 10 years past that model year, or a 2011-or-newer model year that has reached 20 years old.
Does writing “as-is” on the bill of sale protect me from being sued later? Partly. “As-is” generally waives a claim that the car has to work in some particular way, so ordinary wear and unknown defects are usually covered. It typically does not protect a seller who lied about a known problem, hid a branded title, or misstated the odometer reading, since those count as misrepresentation rather than a condition dispute.
What happens if I never file my state’s release-of-liability form? Your name can stay attached to the car in the state’s own records even after you hand over the keys and cash. Parking tickets, toll citations, or camera violations the new owner racks up can keep arriving addressed to you. The state has no record that you are no longer the owner until you file the form yourself.
Does the FTC’s Buyers Guide requirement apply to me if I’m selling my own car? No. The Federal Trade Commission’s Used Car Rule and its Buyers Guide window sticker apply only to dealers who sell or offer for sale more than five used vehicles in a 12-month period. Someone selling one personal vehicle is not a dealer under that rule and does not have to provide a Buyers Guide.
How soon does the buyer have to put the car in their own name? That depends on the buyer’s state, and it is a separate deadline from the seller’s release-of-liability filing. In California, the buyer has 10 days after the purchase to complete the title transfer. The seller has a separate 5-day deadline to file the release-of-liability notice, regardless of whether the buyer has finished their side yet.
