California Small Claims — Key Facts

Step-by-Step: Suing a Contractor in California
Confirm your claim is within California's $12,500 limit
California's small claims limit is $12,500 (Individuals. Businesses capped at $6,250.). If your damages are higher, you can reduce your claim to the limit or file in California civil court. Use our California Small Claims Limit guide for the full details.
Send a demand letter first
Send a certified mail demand letter giving the contractor 10–14 days to refund or return to complete the work. Courts view this positively and it may resolve the dispute without trial. Courts in California expect plaintiffs to have made a good-faith attempt to resolve the dispute. A demand letter also creates a paper trail and often prompts payment without any court filing.
Gather your evidence
Your case is only as strong as your evidence. Collect everything before filing — see the checklist below for exactly what you need for a contractor dispute.
Find the right California courthouse
File at the Small Claims Court in the California county where the contractor is located, does business, or where the dispute occurred. Before filing, look up the contractor's correct legal name and registered agent on the California Secretary of State →. Using the wrong legal name is a common reason cases are dismissed.
Pay the filing fee ($30–$100)
California small claims filing fees range from $30 to $100 depending on your claim amount. Use our California Filing Fee Calculator to find the exact amount for your claim. Keep your file-stamped copy.
Serve the defendant properly
The contractor must be formally notified of the lawsuit. California courts provide specific instructions — follow them exactly. Improper service is one of the most common reasons cases are dismissed.
Present your case at the hearing
Bring 3 organized copies of all evidence. Present your case in order: what happened, how much you lost, and why the contractor is responsible. Most California small claims hearings last 15–30 minutes. Stay calm, stick to facts, and let the judge ask questions.
Sample Demand Letter: Contractor Dispute
Send this demand letter via certified mail before filing. Courts view prior good-faith attempts favorably, and many disputes settle at this stage. Replace the bracketed placeholders with your details.
I am writing to demand payment of $[AMOUNT] in compensation for [INCIDENT DESCRIPTION], which arose from work performed by [DEFENDANT NAME] on or around [DATE] that was incomplete, defective, or failed to meet the agreed specifications. As [PLAINTIFF NAME], I hired you under a written agreement, paid in full or in part, and the work you delivered has required remediation at my expense or remains unfinished. This letter is my formal demand for reimbursement of costs incurred to correct your work, or for a refund of monies paid for work not completed. If I do not receive payment or a written resolution within 14 days, I will file a claim against you in small claims court.

Tips for Winning Your Contractor Case in California
Get at least one written estimate from another licensed contractor to fix or finish the work — this becomes your damages evidence.
Check if the contractor is licensed and bonded in your state. Unlicensed contractors may have committed fraud — a stronger claim.
If the contractor is a business (LLC or corporation), sue the business entity AND the individual owner if they personally dealt with you.
Bring the original contract, any change orders, and all payment receipts. Courts need to see the full financial picture.
