Not legal advice. This page explains what the form asks; it does not tell you what to put in your case.

What it is

A record of completed service

POS-010 tells the court what papers were served, on whom, where, when, how and by whom. The form requires a separate proof for each party served. It is a record of service, rather than a request to have someone served.

When it is used

The server supplies the service facts

The official service guide describes a server who is at least 18 and not a party to the case. The server completes the proof and signs it. Which service method is allowed depends on the case and the papers.

Before you file

Common filing problems to check

These checks come from the official form and instructions. They are not a ranking of rejection reasons; the court decides whether a filing meets its requirements.

  • The server’s signature or date is missing.
  • A date, time, service address or document list required by the selected method is incomplete.
  • An acknowledgment, mailing or diligence attachment referenced by the selected method is absent.
  • One proof is used for several parties despite the form’s separate-proof instruction.

Questions

POS-010 questions

Who signs POS-010?

The person who served the papers signs the declaration. A California sheriff or marshal may use the form’s certification.

Does a completed proof guarantee valid service?

No. The facts and method must satisfy the applicable law. Lexary’s document check cannot decide a disputed service issue.

Does Legal Hub Group offer process serving?

Yes. Legal Hub Group offers process serving in all 50 states. Ask about service separately from the e-filing of a proof.

Not legal advice. This page explains public filing information. It does not tell you what to put in your own case. Legal Hub Group is a certified e-filing service provider for California courts, not a law firm.
