California Civil Subpoena Checklist for Witnesses and Evidence
A practical overview of California civil subpoenas for a witness or documents at a trial or hearing, based on California Courts Self-Help. It provides general procedural information, not individualized legal advice.
- First decide what is needed: a nonparty witness's testimony, documents or other evidence, or both. A subpoena is a court order, so use the procedure that matches the request and the stage of the case.
- For a nonparty witness who only needs to appear and testify at a civil trial or hearing, California Courts identifies Civil Subpoena for Personal Appearance at Trial or Hearing, form SUBP-001.
- When the witness must appear and bring documents or other things to a trial or hearing, use the California Courts instructions for a subpoena duces tecum and the current form identified there.
- Complete the caption and witness information carefully, then take the unsigned subpoena to the court clerk for issuance. Do not sign for the clerk or assume a downloaded blank form is already enforceable.
- Arrange valid service by a qualified adult who is not a party to the case. Follow the current California Courts instructions for personal service, proof of service, witness fees and mileage.
- Describe requested records or things with enough specificity that the recipient can understand what must be produced. Avoid requesting irrelevant or unnecessarily broad material, and review privacy or consumer-notice rules when records concern a person.
- Calendar service and objection deadlines using the current official instructions and any local court rules. Build in time to address an objection or service problem before the hearing or trial.
- Keep copies of the issued subpoena, attachment, proof of service and fee payment, and confirm logistics with the witness without changing the court order. For questions about privilege, privacy, objections or case strategy, consult a qualified lawyer.
