Car Sale Dispute in Washington Small Claims Court

A buyer is suing you over a car you sold privately. Maybe the engine died a week later, or they discovered rust the test drive didn't reveal. Private vehicle sale disputes are among the most common small claims cases in Washington, and how you documented the sale matters as much as what actually happened to the car.

The "As-Is" Question

Washington does not have a state-level "lemon law" that covers private sales between individuals. Lemon law protections under RCW 19.118 apply only to purchases from licensed dealers. A private sale can include an "as-is" term, but any express promise about the car's condition can still matter, whether made orally or in writing.

If you sold the car "as-is" — and especially if the bill of sale says so — that term can support a defense that the buyer accepted the risk of mechanical problems. That's your strongest defense. Bring the signed bill of sale showing the as-is language, the sale price, and both parties' signatures.

If there's no written bill of sale, the case turns on what you said and what the buyer can prove you said. Text messages and emails from before the sale become critical evidence.

When the Buyer Has a Case

An as-is sale doesn't protect you from fraud. If you knew about a serious defect and lied about it — told the buyer the transmission was fine when you knew it was failing, or rolled back the odometer — the buyer can argue fraudulent misrepresentation. The as-is disclaimer doesn't override intentional deception.

The buyer would need to show:

1. You knew about the defect before the sale
2. You made a false statement about the car's condition
3. The buyer relied on that statement when deciding to buy
4. The buyer suffered actual financial loss

If the buyer is simply unhappy that a used car had problems, without evidence that you concealed anything, the claim is much weaker.

Dollar Limits

Private vehicle sale disputes between individuals fall under the $10,000 small claims cap for natural persons under RCW 12.40.010. Venue is typically the county where you (the defendant) reside, or where the sale took place under RCW 3.66.040.

What to Bring to the Hearing

• The bill of sale — especially if it includes "as-is" language, a description of the vehicle, and the sale price
• Department of Licensing transfer documents — proof that you transferred title properly
• Pre-sale communications — text messages, emails, and online marketplace listings (Craigslist, Facebook Marketplace) showing exactly what you advertised about the car's condition
• Maintenance records — if you performed any maintenance before the sale
• Photos of the car taken before the sale — showing its visible condition at the time
• Mechanical inspection records — if the buyer had the car inspected before purchasing (or chose not to)

If the buyer claims the car had an undisclosed defect, you'll need evidence that either you didn't know about it or you disclosed it. A pre-sale mechanic's inspection that didn't find the problem, or messages where you told the buyer about the issue, both work in your favor.

The Price Matters

Judges consider the sale price when evaluating expectations. A buyer who paid $1,200 for a 15-year-old car with 180,000 miles has a different reasonable expectation than someone who paid $8,000 for a 5-year-old car with 40,000 miles. The purchase price is an implicit acknowledgment of the car's condition.

Should You Settle?

If the defect was something you genuinely didn't know about but the buyer can show they relied on your statements, a partial settlement might make sense. Offering to split the repair cost avoids the risk of a full judgment. Put any settlement in writing and file notice with the court.
