In federal court, a subpoena has to be served in person. Federal Rule of Civil Procedure 45 requires that a copy be delivered by hand to the individual named in the document, and courts read the word “delivering” strictly: not mail, not email, not leaving it with a roommate.1Legal Information Institute. Federal Rule of Civil Procedure 45 – Subpoena State courts sometimes permit alternatives such as certified mail or substituted service, so the answer can change if your case is in state court. But for anything moving through a federal courtroom, plan on hand-delivery or expect the service to fail.
What Personal Service Actually Requires
Personal service under Rule 45 means the server identifies the correct person and places the subpoena in that person’s hands. Leaving it on a doorstep does not count. Slipping it under a door does not count. Handing it to a spouse, a roommate, or a receptionist does not count. The recipient has to receive it directly.
This is stricter than the rule for starting a lawsuit. When a plaintiff files a civil case, Federal Rule of Civil Procedure 4 lets the summons and complaint be left at the defendant’s home with a responsible adult, delivered to an authorized agent, or served through state-law alternatives that can include mail.2Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons Rule 45 offers none of those fallbacks. The reason is practical: ignoring a subpoena can lead to contempt, fines, or jail time, so the courts want proof that the person actually got the document.
Who Is Allowed to Deliver It
Any person who is at least 18 years old and is not a party to the case may serve a federal subpoena.1Legal Information Institute. Federal Rule of Civil Procedure 45 – Subpoena No badge, no license, no special training is required by the rule itself.
In practice, most subpoenas go out through professional process servers or sheriff’s deputies. Servers who do this work full-time know how to locate people, document the delivery, and deal with someone who is trying to avoid being found. Fees for professional service usually run between $45 and $125 for a standard delivery, with higher charges for rush jobs or hard-to-locate recipients. The party issuing the subpoena pays for service.
What Must Be Handed Over With the Subpoena
When a subpoena requires someone to appear and testify, the server must also tender fees for one day of attendance and mileage at the moment of delivery.1Legal Information Institute. Federal Rule of Civil Procedure 45 – Subpoena Failing to include those fees can render the service defective and give the recipient grounds to challenge the subpoena.
The attendance fee is $40 per day, set by federal statute.3Office of the Law Revision Counsel. 28 USC 1821 – Per Diem and Mileage Generally Mileage is paid at the rate the General Services Administration sets for federal employees driving private vehicles, currently 72.5 cents per mile for 2026.4General Services Administration. GSA Bulletin FTR 26-02 One exception applies when the federal government itself issues the subpoena: no fees or mileage need to be tendered at service.1Legal Information Institute.

Where Service Can Happen
Rule 45 also caps how far a subpoena can reach. A person can be compelled to attend a trial, hearing, or deposition only within 100 miles of where they live, work, or regularly conduct business in person.1Legal Information Institute. Federal Rule of Civil Procedure 45 – Subpoena The same 100-mile ceiling applies to subpoenas demanding documents or inspection of property.
Two narrow exceptions extend that reach for trial attendance. A party, or an officer of a party, can be required to attend trial anywhere within the state where they live or work. A nonparty witness can be required to attend trial anywhere in the same state as long as doing so would not cause substantial expense.1Legal Information Institute. Federal Rule of Civil Procedure 45 – Subpoena Outside those situations, a subpoena that pulls someone beyond 100 miles must be quashed if challenged. Service delivered outside those geographic bounds is a common defect.
Can a Subpoena Be Served by Mail or Email in Federal Court
No, not under Rule 45 as written. The rule does not authorize service by certified mail, email, fax, leaving copies with a family member, or any method other than personal delivery. This makes subpoena service one of the strictest corners of federal civil procedure. Attorneys sometimes ask judges to permit substituted service when a recipient is actively dodging a process server, but the outcomes vary and any departure from hand-delivery generally requires a specific court order allowing it.
State Courts Are Different
State-court rules do not all follow the federal approach. Some states allow subpoenas to be served by certified mail. Some allow copies to be left with an adult at the recipient’s home. Others carry their own alternatives spelled out in their procedural codes. If your case is pending in state court, look at that state’s rules directly rather than assuming the federal in-person requirement controls. The answer to whether personal service is required can flip entirely depending on the courthouse.
What Happens if Service Is Defective
Proper service is the foundation for everything a subpoena can do. If the delivery was flawed, the recipient has no legal duty to comply and cannot be held in contempt for ignoring it. That is why defective service is the first thing a lawyer checks when a client wants to fight a subpoena.
The recurring defects are the same ones described above: the document was left with someone other than the named recipient, the required attendance fee and mileage were not tendered, or the subpoena was served at a place outside the 100-mile limit. Any of these can support a motion to quash.1Legal Information Institute. Federal Rule of Civil Procedure 45 – Subpoena When a subpoena is quashed on service grounds, the issuing party has to re-serve it correctly and absorb the added cost and delay. In a case with tight deadlines, that failure can mean losing access to a witness or a set of records entirely.
If you are the one issuing the subpoena, the safest path is a professional server, personal delivery to the named individual, the correct fees in hand, and a location within the geographic reach of the rule. If you are the one receiving a subpoena and something about how it arrived seems off, that detail is worth flagging to a lawyer before the compliance date runs.
