Quick answer

Form POS-040, Proof of Service—Civil (Rev. January 1, 2020), is the Judicial Council of California form used to prove that court papers in a civil case — such as a motion, opposition, declaration (Form MC-030), continuation attachment (Form MC-025), or case management statement — were served on the other parties by an adult (age 18 or older) who is NOT a party to the action. It covers personal service, mail, overnight delivery, messenger, fax, and electronic service (or use POS-050/EFS-050 for dedicated electronic service, and POS-010 for a Summons and Complaint). Because the official Judicial Council PDF is an Adobe LiveCycle XFA file that triggers the "Please wait..." screen in Chrome, Safari, and Mac Preview, JustFill lets you fill POS-040 cleanly in any browser and download a court-ready PDF.

What is POS-040?

Filing a motion, declaration (Form MC-030), or response in a California Superior Court civil case and need to file Proof of Service? Under the California Code of Civil Procedure (§§ 1011, 1013, 1013a, 2015.5), a party to a lawsuit cannot serve their own court papers. Instead, someone who is at least 18 years old and not a party to the action delivers, mails, or transmits the copies and signs Form POS-040 under penalty of perjury. JustFill eliminates the Adobe LiveCycle XFA "Please wait..." error on the Judicial Council POS-040 PDF so self-represented litigants, paralegals, and law firms can complete Pages 1–3 in the browser and export a flattened PDF ready for California court e-filing portals.

The Judicial Council of California publishes Form POS-040 (Rev. January 1, 2020, Form Approved for Optional Use, 3 pages including instructions on Page 2–3) at courts.ca.gov/documents/pos040.pdf. Because the Judicial Council file is an Adobe LiveCycle XFA PDF that shows "Please wait... If this message is not eventually replaced" in Chrome, Edge, Safari, and macOS Preview, click "Fill the blank POS-040 now" above to open an interactive POS-040 worksheet in JustFill, or upload your POS-040 PDF to complete and flatten it for court e-filing.

Who fills out POS-040?

  • Non-party adults (friends, relatives, coworkers, legal assistants, or registered process servers) who served civil court documents on behalf of a litigant
  • California civil litigation paralegals and legal secretaries preparing Proofs of Service for motions, discovery, and MC-030 declarations
  • Self-represented plaintiffs and defendants preparing the POS-040 caption and document list for their server to review and sign
  • Registered California process servers documenting personal, mail, or overnight delivery of civil filings

Field-by-field breakdown

What each section of POS-040 asks for. JustFill’s AI will detect these fields automatically when you upload the PDF — review the breakdown below so you know what to enter.

Caption — Attorney or Party Without Attorney, Superior Court, Parties & Case Number

Filing party's or attorney's name, State Bar number, address, phone, and email; Superior Court county and courthouse address; Plaintiff/Petitioner, Defendant/Respondent; Case Number; and optional Hearing Date, Time, and Department.

Items 1–3 — Server Qualification, Server Address & List of Documents Served

Confirms the server is over 18 and not a party to the action (Item 1), gives the server's residence or business address (Item 2), and lists the exact title of every document served (Item 3 — or checks the box for Attachment POS-040(D) if the list is long).

Item 4 — Date, Time & Address of Service (Persons Served)

Date and (when applicable) time of service, plus the name and physical/mailing/fax/electronic service address of the person served (or check the box for Attachment POS-040(P) when serving multiple parties/attorneys).

Item 5a–f — Method of Service Checkboxes

Selects how the documents were served: 5a Personal Service (with details if left at an attorney's office or party's residence), 5b United States Mail (direct deposit or ordinary business practice for collection and mailing), 5c Overnight Delivery, 5d Messenger Service, 5e Fax Transmission, or 5f Electronic Service.

Item 6 / Server Declaration & Signature Block (Page 1)

Server's printed name, date, and signature under penalty of perjury under the laws of the State of California (plus an optional non-perjury certificate block for a California sheriff or marshal).

Common mistakes to avoid

  • 1Signing Form POS-040 yourself when you are the plaintiff, defendant, petitioner, or respondent — California law strictly prohibits a party to the action from serving their own papers or signing the Proof of Service.
  • 2Using Form POS-040 to prove service of an initial Summons and Complaint — the face of POS-040 explicitly warns "Do not use this Proof of Service to show service of a Summons and complaint"; use Form POS-010 instead.
  • 3Uploading the unflattened Judicial Council XFA PDF directly to a California Superior Court EFSP e-filing portal, which rejects encrypted LiveCycle XFA streams.
  • 4Checking Item 5b(2) ("placed the envelope for collection and mailing, following our ordinary business practices") when the server is an individual mailing the envelope at a USPS mailbox rather than an office employee using a regular business mail-collection system (an individual drops it in the mail and checks Item 5b(1)).

POS-040 example — what a filled-out form looks like

In a fictional Sacramento County Superior Court civil case, an adult non-party friend (Marcus Sample) mails copies of the defendant's Notice of Motion to Continue Trial and Declaration on Form MC-030 to the plaintiff's attorney via first-class U.S. Mail and completes Form POS-040.

Caption — Party, Court, Case Name, Case Number & Hearing Details

Jane Sample (In Pro Per), 100 Sample St, Sacramento, CA 95814 · Superior Court of California, County of Sacramento · Sample Property Management LLC v. Jane Sample · Case No. 26CV•••••• · Hearing: 10/12/2026, Dept. 53

Matches the caption of the motion and Form MC-030 declaration being served.

Items 2 & 3 — Server's Address & Documents Served

Item 2 Server Address: 450 Sample Oak Ave, Sacramento, CA 95816 · Item 3 Documents: (1) Defendant's Notice of Motion and Motion to Continue Trial; (2) Declaration of Jane Sample in Support of Motion (Form MC-030)

Lists the server's address and the exact title of every document placed in the envelope.

Items 4 & 5b — Person Served & Service by United States Mail

Item 4: Served on 09/02/2026 to Richard Roe, Esq., Counsel for Plaintiff, 800 Sample Mall Suite 400, Sacramento, CA 95814 · Item 5b ☑ By United States mail · ☑ 5b(1) Enclosed in a sealed envelope and deposited with USPS with postage fully prepaid in Sacramento, CA

Because the server personally dropped the stamped envelope at the post office in Sacramento, Item 5b(1) applies.

Declaration & Signature of Server (Bottom of Page 1)

Dated: September 2, 2026 · MARCUS SAMPLE · Signed by Marcus Sample (Non-party adult server)

Must be signed under penalty of perjury by the non-party adult who performed the mailing — never by the party in the case.

These values are made up. They are here to show what belongs on each line, not to be copied — every name, number, and address on your own POS-040 has to be your own.

Frequently asked questions

The Judicial Council of California distributes Form POS-040 as an Adobe LiveCycle XFA PDF with owner-password restrictions. Chrome, Edge, Safari, Firefox, and macOS Preview cannot render LiveCycle XFA scripts, and California court e-filing portals reject unflattened XFA files. JustFill lets you complete POS-040 in any browser and exports a standard flattened PDF.
No. Even when you are self-represented, Item 1 of Form POS-040 states: "At the time of service I was over 18 years of age and not a party to this action." Ask a friend, relative, coworker, or professional process server who is at least 18 and not named in the case to mail or deliver the papers and sign POS-040.
Use Form POS-010 (Proof of Service of Summons) only to prove service of the initial Summons and Complaint. Use Form POS-040 for subsequent filings in civil cases (such as motions, oppositions, and Form MC-030 declarations). In family law cases (divorce, custody, FL-150, FL-300), California courts commonly use Form FL-335 (Proof of Service by Mail) or Form FL-330 (Personal Service).
Check the attachment box in Item 3 and attach Form POS-040(D) (Attachment to Proof of Service—Civil: Documents Served) for extra documents, or check the attachment box in Item 4b and attach Form POS-040(P) (Persons Served) when serving multiple parties or attorneys.
