Free Proof of Service and Certificate of Service Generator
Build a complete proof of service form with the court caption, the documents served, the right declaration for personal delivery, mail, overnight delivery, or electronic service, and a signature block, then download it as a PDF or Word file. No signup, no email required.
Quick answer: A proof of service form is the signed statement filed with the court showing that the other parties received copies of a document: who served it, what was served, when, how, and on whom. It is usually signed under penalty of perjury by the person who did the serving, and courts will not act on a filing the other side never provably received. Use the generator below to build one, then compare it against your court's rules, because some courts require their own mandatory form.
Reuse your case details across our tools?
Type the caption once and fill it into the deadline calculator, proof of service, pleading paper, filing packet, and pre-flight checker. Saved on this device only, in this browser. It is never sent to us, and "Forget" deletes it rather than blanking it.
Document Title
Courts use two naming conventions for the same job. Federal courts and many state courts use "Certificate of Service"; many state courts, California among them, use "Proof of Service". Match whatever the other filings in your case use.
Court Caption
Copy the caption exactly as it appears on the complaint or petition in your case, including the case number. Anything left blank prints as a ruled line to complete by hand.
Documents Served
List the exact title of every document served, as it appears on the document's first page. Courts reject proofs of service that describe the papers vaguely.
Date & Method of Service
The method you choose controls the declaration language in the document. Confirm the method is one your court's rules allow for the papers you are serving.
The business-practice statement is the standard wording for offices where outgoing mail is collected and deposited the same day in the ordinary course of business.
Person(s) Served
Add every person or attorney served. For a represented party, serve the attorney of record and use a designation like "Attorney for Defendant Acme Widgets, Inc."
Who Served the Documents
The person who actually delivered, mailed, or transmitted the documents signs this form. The document recites that the server is at least 18 years old.
Declaration & Signature
Most proof-of-service forms are signed under penalty of perjury. The exact wording a court accepts varies by jurisdiction; the version here is generic, so compare it against your court's form if one exists.
Before you file this document: some courts require their own mandatory proof-of-service form, and the rules on who may serve, whether a party may serve, allowed service methods, and the exact perjury wording all vary by jurisdiction and by document type. Compare this document against your court's rules and any court-issued form before filing. This tool provides general information, not legal advice, and is not a substitute for a licensed attorney.

What a Proof of Service Form Does
Nearly everything filed in a lawsuit must also be delivered to every other party, and the court needs written evidence that the delivery happened. That evidence is the proof of service form: a short document reciting the case caption, the exact titles of the documents served, the date of service, the method of service, the people served with their addresses, and the identity of the server, closed with a signature, in most courts under penalty of perjury. Judges treat it as the record that due process was satisfied. If it is missing or defective, the filing it accompanies is vulnerable.
The same instrument travels under several names: proof of service, certificate of service, declaration of service, and, when it is sworn before a notary, affidavit of service. The substance barely changes across the names. What changes is the convention your court follows, who signs, and the exact declaration wording your jurisdiction accepts. If you need the underlying filing drafted as well, our legal document drafting services prepare motions, answers, and discovery documents to your court's format, with the service paperwork included, and you sign, serve, and file.
Key Point: Some Courts Require Their Own Mandatory Form
A number of courts publish a required proof-of-service form and expect filers to use it, and clerks in those courts can reject a home-built version even when its content is correct. Before filing, check your court's website or clerk's office for a mandatory or preferred form. If one exists, use it, and use the document from this generator as your worksheet so every blank on the official form is filled accurately.
Proof of Service vs Certificate of Service Template
The two names describe the same job done under different conventions, and using the right one makes your filing look like it belongs in the courtroom it lands in. A proof of service is the convention in many state courts: a standalone page, signed under penalty of perjury by the person who actually served the documents, often a non-party. A certificate of service template follows the convention used in federal court and many state courts: a brief certification, commonly placed at the end of the filed document itself, signed by the filer or the attorney of record, stating that a copy was served on all other parties on a stated date by a stated method.
The differences are real but mechanical: the title, who signs, whether it stands alone or rides with the filing, and whether the signature carries penalty-of-perjury wording or a simple certification. The generator above toggles between both title conventions and lets you switch the closing between a perjury declaration and a plain certification. What it cannot do is know your court's local practice, so match whatever the other filings in your case use, and when in doubt, ask the clerk. For a fill-in-the-blank starting point you can compare against, our proof of service template covers the same ground in static form.
Service Methods: Proof of Service by Mail, Personal Delivery, Overnight, and E-Service
Each method of service carries its own declaration language, because the server is swearing to different facts. The generator swaps in the correct declaration for the method you pick. The table below summarizes what each declaration states and what to watch for. Which methods are allowed for which documents varies by court and by document type.
| Method | What the Declaration States | Watch For |
|---|---|---|
| Personal delivery | A true copy was hand delivered to each person at the address shown, on the stated date | Note who accepted the papers if it was not the named person |
| A sealed, addressed envelope with prepaid postage was deposited with the postal service, or placed for collection under ordinary business practice | State the city and state of mailing; mail service often adds response time | |
| Overnight delivery | The package was placed with an overnight carrier, fees paid, addressed to each person served | Name the carrier and keep the tracking record |
| Electronic service | Documents were emailed to agreed electronic service addresses, or served through the court's e-filing system to its registered users | Usually requires the recipient's consent or a court e-service order |
Warning: Electronic Service on a Party Often Requires Their Consent
Emailing a filing to the other side feels like service, but in many courts it only counts if that party expressly consented to electronic service or the court ordered e-service. The trap snaps shut most often on service to self-represented parties, who typically have not consented and are not registered in the court's e-filing system, so system notifications never reach them. From our own drafting work we can say this is one of the most common ways an otherwise clean filing gets challenged. Before serving electronically, confirm consent or an order, and when in doubt, serve by mail or personal delivery as well.
Who Can Serve, and Who Signs the Declaration of Service
The person who signs a declaration of service must be the person who actually did the serving: whoever handed over, mailed, or transmitted the documents. Courts commonly require that person to be at least 18 years old, and many require the server to be someone who is not a party to the action, especially for the summons and complaint that start a case. Some jurisdictions go further and require certain papers to be served by a sheriff, marshal, or registered process server. Whether a party may serve, and which documents they may serve, varies by jurisdiction, so we will not pretend there is one national rule: check the rules of the court where your case is pending.
The signature itself matters as much as the signer. Most proof-of-service forms are signed under penalty of perjury, and the exact perjury wording a court accepts also varies by jurisdiction; a few courts still expect a notarized affidavit of service in some situations. The generator on this page uses generic declaration wording and marks the state line as a blank when you have not filled it, precisely so you compare it against your own court's form. If your case involves heavier lifting than a service form, our litigation support services handle drafting, document review, and deposition summaries for cases at any stage.
How to Fill Out a Proof of Service, Step by Step
Knowing how to fill out a proof of service comes down to five sections done precisely. First, the caption: copy the court name, party names, and case number exactly as they appear on the complaint or petition, because clerks match filings by caption. Second, the document list: state the full title of every document served, as printed on its first page, not a summary like "discovery papers". Third, the date and method: pick the method actually used and keep the declaration language that matches it, since each method swears to different facts. Fourth, the people served: list each person with their party designation, for a represented party that means the attorney of record, and the address or electronic service address where service was made. Fifth, the server's details and signature: the server's name and address, the recital that the server is at least 18, whether the server is a party, and the signed declaration with its date and place.
Two habits prevent most rejections. Fill the form out the same day service happens, while the details are exact, and keep the supporting record: the certified mail receipt, the tracking number, the sent email, or the e-filing confirmation. The proof of service says what happened; the record proves it if service is ever challenged. If you are serving an answer, our answer to civil complaint template pairs naturally with this form, and a subpoena template is the other filing that nearly always travels with a service declaration.
Common Defects That Get Filings Bounced
The Wrong Server
A party serves papers in a court that requires a non-party server, or a document that required a sheriff or registered process server was served by a friend. The service can be invalid even though the papers arrived.
A Method the Rules Do Not Allow
Email service without consent or a court order, or mail service for a document the rules say must be personally delivered. The method must match what the rules permit for that specific document.
Vague Document Descriptions
Listing "motion papers" instead of the exact titles. If the proof of service does not identify precisely what was served, the other side can dispute what they received.
Caption and Case Number Errors
A caption that does not match the case, or a wrong or missing case number, can send the filing to the wrong file or back to you. Copy the caption from the operative complaint or petition.
Dates That Do Not Add Up
A service date after the filing date it claims to support, a missing date, or a signature dated before service occurred. Judges and clerks check the arithmetic.
Missing Signature or Wrong Signer
The form is unsigned, or signed by someone other than the person who actually served. The declaration only works when the person who did the serving swears to it.
Frequently Asked Questions
What is a proof of service form?
A proof of service form is a signed statement filed with the court that tells the judge who was served with a document, what was served, when it was served, how it was served, and who did the serving. Courts rely on it to confirm that the other side actually received the papers, because most orders and judgments are only valid if every party had notice. The form is usually signed by the person who delivered, mailed, or transmitted the documents, and in most courts it is signed under penalty of perjury. Without a proof of service on file, a court can refuse to hear a motion, reject a filing, or set aside a judgment.
What is the difference between a proof of service and a certificate of service?
They do the same job under different conventions. A proof of service is the name most state courts use, and it is typically a standalone declaration signed under penalty of perjury by the person who actually served the documents. A certificate of service is the convention used in federal court and many state courts: usually a short paragraph or page attached to the filed document, signed by the filer or the attorney of record, certifying that a copy was served on every other party. The federal certificate convention differs from state proof-of-service forms in wording, placement, and who signs, so match the convention your court and the other filings in your case use.
How do I fill out a proof of service form?
To fill out a proof of service, complete five things accurately: the case caption (court name, party names, and case number, copied exactly from the complaint or petition), the exact titles of every document served, the date of service, the method of service with the declaration language that matches it, and the name and address of every person served. The server then signs and dates the form, usually under penalty of perjury. The generator on this page walks through each of these sections and prints ruled blanks for anything you leave empty, so nothing is guessed for you.
Who can serve court papers?
It varies by jurisdiction and by document type. A common baseline is that the server must be at least 18 years old, and many courts require the server to be someone who is not a party to the case, especially for the initial summons and complaint. Some states require certain documents to be served by a sheriff, marshal, or registered process server. Because who may serve is set by each jurisdiction's rules, check the rules of the court where your case is pending, or your state's civil procedure statutes, before deciding who signs the proof of service.
Can a party to the case serve the documents?
Often not, and this is one of the most common service mistakes self-represented people make. Many courts prohibit a party from serving documents in their own case, particularly the papers that start the lawsuit, and some restrict party service for later filings as well. Other courts allow a party to serve routine papers by mail. The safest course is to have a non-party adult, a friend, coworker, or professional process server, do the serving and sign the proof of service, and to confirm your court's rule either way.
What is proof of service by mail?
Proof of service by mail is the declaration used when documents are served by first-class mail rather than hand delivery. The server declares that they placed a true copy of the documents in a sealed envelope addressed to each person served, with postage fully prepaid, and either deposited it with the postal service or placed it for collection and mailing under the office's ordinary business practice, the standard business-practice mailing declaration used by law office mailrooms. The declaration also states the city and state of mailing and the date, because many courts add extra response time when service is made by mail.
Does a proof of service have to be notarized?
Generally no. In most United States courts a proof of service is signed under penalty of perjury as an unsworn declaration, which substitutes for a notarized affidavit. A minority of courts and a few situations still call for a notarized affidavit of service instead, and the exact perjury wording a court accepts varies by jurisdiction. Check whether your court asks for a declaration or an affidavit, and if a court-issued form exists, use its wording.
What is a declaration of service?
A declaration of service is the same instrument as a proof of service: a written statement, signed under penalty of perjury by the person who served the documents, describing what was served, on whom, when, and how. Some courts title the document Declaration of Service, others Proof of Service, Certificate of Service, or Affidavit of Service when it is notarized. The substance is nearly identical across the names; what changes is the title convention, who signs, and the exact declaration wording your jurisdiction requires.
Can I serve court documents by email?
Only in the situations your court's rules allow. In many courts, electronic service on a party is valid only if that party has expressly consented to it, or the court has ordered electronic service, and this trips people up most often with self-represented parties, who frequently have not consented and are not registered in the court's e-filing system. Where a case is in an electronic filing system, service through that system usually counts only for the people who are registered users of it. Before relying on email service, confirm consent or a court order, and keep the transmission record.
When do I file the proof of service with the court?
Practice varies. In many state courts the proof of service is filed with the document it accompanies or promptly after service, and for a summons it must generally be filed before the court will enter a default or move the case forward. Under the federal certificate-of-service convention, the certificate is normally part of the filed document itself. Some courts also set specific deadlines for filing proof that a summons was served. Check the rules of the court where your case is pending and any scheduling order in your case.
What happens if my proof of service is defective?
A defective proof of service can get a filing rejected by the clerk, a motion taken off calendar, a default judgment denied or later set aside, or a deadline dispute decided against you. Common consequences flow from common defects: a server who was not allowed to serve, a method the rules do not permit for that document, a missing or wrong date, papers described too vaguely to identify, or a missing signature. If you discover a defect, the usual fix is to serve again properly and file a corrected proof of service, and if a deadline is involved, to address it before the other side does.
