How to File

Small claims are filed at the Hall of Justice (400 County Center, Redwood City). Office visits are by appointment only — schedule before going. Hearings may be held at the Redwood City Hall of Justice or the Northern Branch in South San Francisco — check your notice for the assigned location. Small claims appeals (SC-140) must be filed under 'New Case Filings,' not the existing case number.

Serving the Defendant

Serve the defendant at least 15 days before the hearing (20 days if the defendant lives outside San Mateo County). Service can be made by the San Mateo County Sheriff for a fee, by a registered process server, or by any adult who is not a party. File the proof of service (SC-104) with the court before the hearing.

Allowed methods: Personal service, Substituted service, Certified mail
Deadline: Serve at least 15 days before the hearing date.
