Filing in Contra Costa County, step by step

Every step below happens at Superior Court of California, County of Contra Costa — Small Claims or through the system it uses.

1. 1. Check the amount is within the limit. Contra Costa County small claims handles claims up to $12,500 (individual limit; an entity or other non-natural person may claim only up to $6,250). Above that, the case belongs in a different division and the clerk will refuse it.
2. 2. Name the defendant exactly. A judgment against a misspelled name or a trade name that is not the legal entity is difficult to collect. For a business, use the registered legal name.
3. 3. Fill out the claim form. Contra Costa County uses SC-100 Plaintiff's Claim and ORDER to Go to Small Claims Court, SC-104 Proof of Service, SC-140 Notice of Appeal (Small Claims). The blank forms are free. What you write in the statement of what happened is what gets the case accepted or sent back.
4. 4. File it and pay. Contra Costa County accepts filings in person at the martinez (725 court street), pittsburg (1000 center drive), or richmond (100 37th street) courthouse; by mail or courthouse drop box to the filing location (small claims cannot be e-filed). The fee is $30–$75.
5. 5. Serve the defendant. Filing does not notify the defendant — service does, and the case cannot proceed without it. Contra Costa County charges $15 per defendant. The plaintiff arranges and pays for service and may not serve the papers personally. Service is made by any adult 18 or older who is not a party, by the county sheriff or marshal for a fee, by a registered process server, or by the court clerk by certified mail where that option is offered.
