Subpoena Service in Contra Costa County, CA — All Court Branches

California Subpoena Service Requirements — What Applies in Contra Costa
Under CCP §1987, subpoenas in California civil cases generally require personal delivery to the named witness. Personal appearance subpoenas must include a witness fee check and mileage reimbursement per California Evidence Code §1563 — failing to tender fees can void the subpoena. Business records subpoenas served on third-party custodians are governed by CCP §2020.410 and may qualify for certified mail service depending on the entity type. Deposition subpoenas have their own format and notice requirements distinct from trial subpoenas. We confirm the correct subpoena type, service method, and fee requirement for every order before dispatch.
