When serving a federal subpoena, the following witness fees and mileage rules apply under FRCP 45 and 28 U.S.C. §1821:
Always document fee tender in your affidavit of service to ensure full compliance with FRCP 45(b).
Serving a federal subpoena is a precise legal process that extends beyond simple document delivery. It involves strict adherence to the Federal Rules of Civil Procedure (FRCP) Rule 45(b) and 28 U.S.C. §1821, which outline the Federal Subpoena Witness Fees that must accompany service. These statutory payments ensure that witnesses are fairly compensated for their time, travel, and related expenses when compelled to appear in federal proceedings.
Failure to properly tender the required fees can invalidate the subpoena or delay proceedings. This makes understanding Federal Subpoena Witness Fees essential for attorneys, process servers, and litigants. Whether you’re serving an expert witness across state lines or a third party in a federal civil matter, knowing the exact fee requirements is critical for lawful, efficient service.
According to FRCP Rule 45(b), every federal subpoena commanding attendance must be served with payment for one day’s attendance and the appropriate mileage compensation. However, there is an exception when the Federal Government itself issues the subpoena—under those circumstances, no fees or mileage are required at the time of service.
The payment of these fees is not optional. The absence of proper tendering may result in the witness’s noncompliance being excused, leaving your subpoena unenforceable. Proper understanding of these fee obligations ensures both fairness to the witness and compliance with procedural law.
Under 28 U.S.C. §1821(b), witnesses attending proceedings in federal court are entitled to $40.00 per day for each day of required attendance. This per diem is applicable whether the witness testifies, waits to testify, or appears for a deposition. In multi-day proceedings, the attendance fee accrues for each day the witness is required to be present.
This daily rate applies to all witnesses, regardless of professional background or travel distance, unless a specific statute authorizes a different rate (such as expert witnesses under contractual agreements).
In addition to the per diem attendance fee, witnesses are entitled to reimbursement for mileage expenses. The standard rate under 28 U.S.C. §1821(c)(2) is $0.70 per mile, calculated on a round-trip basis between the witness’s residence and the place of testimony.
Mileage reimbursement applies whether the witness drives their personal vehicle or travels by another method. Courts typically accept mileage calculations verified through reputable mapping tools such as Google Maps, MapQuest, or Rand McNally.
Historically, mileage was determined using the “uniformed table of distances” from the Department of Defense’s Military Traffic Management Command or other official references. Today, practical tools such as Streets & Trips, MapQuest, and Google Maps are acceptable for computing distances. Courts expect reasonableness and documentation rather than reliance on outdated tables.
If the witness’s home address is unavailable, it may be acceptable to calculate mileage from their business address or another verifiable location. Should an error occur in the initial fee tender, it can be corrected by supplemental payment.
Beyond per diem and mileage, witnesses may recover reasonable travel-related expenses. Under 28 U.S.C. §1821(c)(3), allowable reimbursements may include:
If records are subpoenaed instead of personal testimony, the witness fee is not required, but reasonable copying or production costs may be claimed.
1. What are federal witness fees?
Federal witness fees are statutory payments made to individuals subpoenaed to testify in federal court or provide evidence in a federal case. These payments compensate for time, travel, and related expenses.
2. What law governs federal witness fees?
Federal witness fees are governed by 28 U.S.C. § 1821, which outlines the rates and reimbursement rules for witnesses appearing in U.S. federal courts.
3. How much is the standard federal witness fee?
Under federal law, witnesses are entitled to $40.00 per day for each day of attendance at court or deposition.
4. Are travel expenses reimbursed in addition to the daily fee?
Yes. Witnesses are reimbursed for mileage, tolls, and necessary travel expenses at the rate established by the General Services Administration (GSA) for federal employees.
5. Are witnesses paid for travel days?
Yes. Witnesses receive both the daily attendance fee and travel reimbursement for the days spent traveling to and from court, provided travel is necessary.
6. How are mileage and travel costs calculated?
Mileage is typically reimbursed based on the round-trip distance from the witness’s residence to the court or deposition site, using the current GSA mileage rate (which adjusts annually).
7. Are expert witnesses entitled to higher compensation?
Yes. Expert witnesses may receive reasonable compensation for their time and expertise, which is negotiated or set by the court, and exceeds the $40 per day statutory amount.
8. When must the federal witness fee be paid?
The fee and estimated travel expenses must be tendered at the time the subpoena is served. Without payment, a witness is not legally required to appear.
9. Are government employees or law enforcement officers paid the same fee?
Federal employees testifying in an official capacity are not paid a witness fee; their attendance is considered part of their duties. If testifying in a personal capacity, they are entitled to the standard witness payment.
10. What if a subpoena is served without the required fee?
A subpoena that fails to include the required witness fee and mileage is not legally enforceable until the proper payment is made.
11. Do federal witness fees apply to depositions as well as trials?
Yes. Witnesses attending federal depositions are entitled to the same statutory daily and mileage fees as those appearing in court.
12. How are federal witness fees requested or claimed?
Witnesses typically complete a Standard Form 1157 (Claim for Witness Attendance Fees, Travel, and Miscellaneous Expenses) or provide an itemized receipt submitted to the court or issuing agency for reimbursement.

Case Study 1 — Fee Deficiency Dismissal Avoided
A litigant in the Southern District of New York initially served a subpoena without including witness mileage. Upon realizing the deficiency, they immediately corrected the payment before the compliance date. The court recognized the prompt correction and upheld the subpoena’s validity, reinforcing the importance of timely rectification.
Case Study 2 — Invalid Subpoena Due to Missing Fee
In another federal case, the failure to include the required Federal Subpoena Witness Fees resulted in the court denying a motion to compel testimony. The judge ruled that without proper tender of statutory fees, the subpoena was procedurally defective and unenforceable.
These examples underscore that compliance with Rule 45(b) and 28 U.S.C. §1821 is not merely administrative—it’s a substantive requirement for enforceable service.
