How to Serve a Subpoena and File a Return of Service

To serve a subpoena and file a return of service in federal court, have a qualifying adult hand the subpoena to the named recipient along with the required witness fee, then file the signed return of service with the clerk of the court that issued it. Both steps have to be done correctly. A flaw in either one can void the subpoena and force you to start over.

Who Is Allowed to Serve It

The server must be at least 18 years old and cannot be a party to the case.1Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena If you are the plaintiff or defendant, you cannot deliver the subpoena yourself. Attorneys typically hire professional process servers, and fees for standard service generally run between $20 and $100 depending on location and urgency. Any adult friend, coworker, or relative who is not a party to the lawsuit can also do it. If the person who hands over the subpoena does not meet these requirements, the court can quash the subpoena entirely.

Where and When to Serve

A subpoena may be served at any location within the United States. There is no geographic limit on where the delivery itself can happen. Do not confuse this with the separate 100-mile rule, which governs where a witness can be commanded to physically appear, not where they can be served.1Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena

Federal Rule 45 does not fix a specific number of days between service and the compliance date. The standard is “reasonable time to comply,” and a court must quash a subpoena that fails to give the recipient enough time.1Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena Two days before a cross-country deposition will almost certainly fail that test. Two or three weeks before a local hearing will almost certainly pass it.

One step gets overlooked and matters: if the subpoena commands production of documents or inspection of premises before trial, you have to serve notice and a copy of the subpoena on every other party in the case before you serve the witness.1Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena Skip that, and the subpoena is vulnerable to challenge.

How to Deliver the Subpoena

Personal Service

Personal service means physically handing the subpoena to the named person. It provides the strongest proof of delivery and is the default method for good reason: it leaves the least room for later dispute.

Substituted Service

If the recipient cannot be reached after genuine effort, substituted service allows the server to leave the documents with a responsible adult at the recipient’s home.2Legal Information Institute. Substituted Service That person has to be someone likely to pass the papers along, not just whoever happens to open the door. Courts that permit substituted service often require a follow-up mailing to the recipient as well.

Mail and Electronic Service

Some jurisdictions authorize service by certified mail or commercial carrier when local rules specifically allow it. Those methods usually require a signed return receipt as proof the recipient took possession. Service by email is rare for an initial subpoena. A court will generally only allow it after the requesting party files a motion for alternative service and demonstrates that conventional methods failed despite multiple attempts at different times of day.

Serving a Business

Rule 45 does not spell out who receives a subpoena when the recipient is a corporation or other business entity. Courts often look to Rule 4(h)(1), which governs service of a summons on corporations, for guidance. In practice, that means serving an officer, a managing agent, or, depending on state law, a registered agent or a receptionist at the company’s principal office. Courts are split on exactly how flexible these methods can be, but the standard stays the same: the method has to be reasonably calculated to give actual notice.3United States Courts. Is Personal Service of a Subpoena Required Under Rule 45?

Tender the Witness Fee at the Time of Service

Handing over the subpoena is not enough by itself. When the subpoena requires the person to attend a proceeding, the server must also tender the witness fee and mileage allowance at the moment of delivery.1Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena Skipping this step can render the service defective on its face.

The attendance fee is $40 per day, which also covers travel time to and from the proceeding.4Office of the Law Revision Counsel. 28 USC 1821 – Per Diem and Mileage Generally Mileage is reimbursed at the rate the General Services Administration sets for official federal employee travel. Federal law also provides a subsistence allowance for witnesses who need overnight stays. The usual practice is to give the witness a check for the estimated total when the papers change hands.

One exception: when the subpoena is issued on behalf of the United States or a federal agency, fees and mileage do not have to be tendered at service.1Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena

Filling Out the Return of Service

The return of service is the server’s sworn statement that delivery actually happened. Most subpoenas include a return of service form as the last page of the document itself. If none is attached, the server can usually download one from the clerk of court’s website.

The completed form must include the full name of the person who received the documents, the exact date of service, the physical address where the interaction occurred, and the method of delivery used. The date has to reflect when the subpoena was actually handed over, not when the server signed the form or dropped it in the mail.5U.S. District Court for the District of Columbia. Returns of Service – ECF User’s Manual The server checks the box for the service method used, records the witness fee tendered, and signs the document under penalty of perjury.

The federal rules only require the server to certify the statement, but some local court rules require the signature to be notarized before filing. When you are unsure which applies, notarizing the form eliminates any jurisdictional argument about its validity.

Filing the Proof With the Court

The completed return of service goes to the clerk of the court that issued the subpoena. Most federal courts use electronic filing systems where the document is uploaded as a PDF.5U.S. District Court for the District of Columbia. Returns of Service – ECF User’s Manual Courts without e-filing require hand-delivery of the paper document to the clerk’s office, where it gets stamped with the date and time of receipt. Filing a return of service does not typically carry a separate court fee in federal court. State courts vary.

After filing, send a copy of the file-stamped proof to all other attorneys or self-represented parties in the case. That puts everyone on notice that the witness is now under a legal obligation to comply.

Why Getting This Right Matters

A properly served subpoena is enforceable through the court’s contempt power under Rule 45(g), which can lead to fines or imprisonment for a witness who ignores it without adequate excuse.1Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena A defectively served one is not. If service was flawed, if witness fees were never tendered, or if the paperwork on file does not match what actually happened, the recipient has a ready defense and you have to serve them all over again, often after the proceeding date has already slipped. The mechanical steps in this rule exist precisely so that the enforcement power on the other side of them holds up.
