Used car sold with undisclosed problems — suing in California small claims court
Get a mechanic to put in writing that the defect pre-dated the sale and would have been known to the owner. That written opinion is what turns "as-is" from a shield into a side issue.
General information about California procedure. We are not a law firm and cannot advise on your case.
Your deadline to file
3 years — Fraud or deceit, where the seller concealed a known defect (Code Civ. Proc. § 338(d)).
4 years for breach of a written warranty or contract (Code Civ. Proc. § 337).
The rule that decides most of these cases
A private "as-is" sale is genuinely as-is in California, but as-is does not license active concealment. A seller who knew about and hid a defect, or lied when asked, can still be liable for fraud.
What this kind of case is worth
Used car dispute claims in California small claims court typically run from $500 to $12,500. An individual may claim anything under $12,500; an entity is capped at $6,250.
| Amount you are claiming | Filing fee |
|---|---|
| up to $1,500 | $30 |
| over $1,500 up to $5,000 | $50 |
| over $5,000 up to $12,500 | $75 |
| More than 12 small claims filed in the past 12 months | $100 |
How to start
Before you file, you have to have asked the defendant to pay — the SC-100 asks you to confirm it. A written demand with a deadline does three useful things at once: it satisfies that requirement, it creates a dated record the judge can see, and quite often it ends the dispute without a filing fee.
If the letter does not work, file SC-100 with the small claims division of the Superior Court in the right county — generally where the defendant lives or does business, or where the deal was made or performed.
What to bring to the hearing
A small claims judge has minutes, not hours. Walk in with these, each one labelled, plus a copy for the judge and a copy for the other side.
- The bill of sale and the advertisement as it appeared
- The title and odometer disclosure
- Messages where you asked about condition and what they answered
- A mechanic's written inspection identifying the defect and how long it existed
- Repair estimates and invoices
- Vehicle history report
What they will argue back
Expect one of these. Knowing which is coming is most of the preparation.
- They rely on the as-is term
- They claim they did not know
- They claim the problem developed after the sale
Serving the papers
Filing is not the hard part. Service of process is where self-represented cases most often come apart. The defendant has to be formally notified, you cannot do it yourself, and you must file proof that it happened on form SC-104 before the hearing. Use the sheriff, a registered process server, or any adult who is not a party to the case.
The hearing
You cannot bring a lawyer to argue for you at a California small claims hearing. Neither can the other side. That is the whole point of the forum: the rules are simplified so two people can explain a disagreement to a judge without needing representation. You may get advice from an attorney before and after, and lawyers are permitted on appeal — but on the day, it is you.
Common questions
I bought it as-is. Do I have any claim?
Possibly, if the seller actively concealed or misrepresented something. As-is allocates the risk of unknown faults to you; it does not protect a seller who knew the transmission was failing and said it drove perfectly. The case turns on proving knowledge, which is why a mechanic's opinion on how long the defect existed matters so much.
Is a dealer different from a private seller?
Very. Licensed California dealers are subject to extensive regulation, implied warranties can apply, and the DMV has an investigations division that takes complaints. If you bought from a dealer, complain to the DMV as well as sending your demand — you have considerably more leverage than against a private seller.
