Serving California Civil Lawsuit Papers: A Practical Checklist
A general-information checklist for formally serving a California civil Summons and Complaint and filing proof of service, based on official California Courts instructions. It is not individualized legal advice or a deadline calculation.
- After filing, collect file-stamped copies of the Summons, Complaint and every paper the court says must be served. California Courts explains that filing alone does not notify the defendant; formal service is required.
- Identify exactly who must be served and the correct person authorized to receive papers. Rules differ for an individual, business, public entity, minor, person under a conservatorship or someone outside California or the United States.
- Choose a permitted method using the current California Courts instructions. Personal service is the most direct method, while substituted service or service by mail with a notice and acknowledgment has additional conditions and completion rules.
- Use a server who is at least 18 and is not a party to the case. A sheriff, registered process server or another qualified adult may serve when the applicable rules allow it; the plaintiff cannot personally serve the papers.
- Give the server complete copies, accurate identifying information and enough time to complete service. Keep a log of attempts and communications, especially if the person or authorized agent is difficult to locate.
- Have the server complete Proof of Service of Summons, form POS-010, accurately. The server—not the plaintiff—signs the proof describing what was served, on whom, when, where and by which method.
- File the completed proof with the court and keep a filed copy. Review the docket to confirm receipt, but do not assume the defendant's response period or any later deadline without checking the rules for the actual method and date of service.
- If ordinary service cannot be completed, do not improvise. Alternative service can require additional efforts, declarations or a court order. Use the official resources below and consult a qualified lawyer or court self-help center for a specific case.
