To serve someone in the military, you confirm they are on active duty, locate their duty station, and then choose a method the court will accept: a mailed waiver of service, a civilian process server coordinated through the installation’s legal office, or, for members abroad, service through the Hague Service Convention or a letter rogatory. Federal law adds two things a civilian case does not have: you must tell the court whether the defendant is on active duty before any default judgment, and the defendant can ask the court to pause the case while military duties prevent them from responding.
Confirm Active-Duty Status Before You Do Anything Else
The Defense Manpower Data Center runs a public website for exactly this purpose. You create an account, enter the person’s name and Social Security number, and the system checks DEERS to confirm whether the individual is on active duty, left active duty within the past 367 days, or has orders to report. It returns a downloadable certificate you can file with the court.1Defense Manpower Data Center. Servicemembers Civil Relief Act The site will not tell you where the person is stationed; it only confirms status.
This step is not optional if there is any chance the defendant will not appear. Before a court can enter a default judgment in any civil case where the defendant has not appeared, the plaintiff must file an affidavit stating whether the defendant is or is not in military service, backed by facts showing how the plaintiff knows. If you cannot determine the answer, the affidavit has to say so. Knowingly filing a false military status affidavit is a federal crime carrying a fine, up to a year in prison, or both.2Office of the Law Revision Counsel. 50 USC 3931 – Protection of Servicemembers Against Default Judgments Run the check even when you believe the person has separated.
If the court confirms active-duty status and the defendant has not appeared, it cannot enter judgment until it appoints an attorney to represent them.2Office of the Law Revision Counsel. 50 USC 3931 – Protection of Servicemembers Against Default Judgments If status is genuinely unknown, the court may require you to post a bond to cover losses the defendant would suffer if the judgment were later overturned.
Find the Duty Station
Every branch except the Coast Guard operates a locator service that can help you find an active-duty member’s current duty station. You will generally need the full name plus identifying details such as rank, Social Security number, date of birth, or last known assignment. The Army, Navy, Air Force, and Marine Corps each maintain separate locator offices reachable by phone or mail.3USAGov. Contact an Active Duty Service Member or Retiree
If you already know the branch and general location, you can often skip the locator and contact the installation’s legal office directly. In family cases, a leave and earnings statement sometimes lists the member’s legal domicile, but domicile is not the same as the physical duty station where you would deliver papers.
Start With a Waiver of Service
Before arranging base access or a process server, consider Federal Rule of Civil Procedure 4(d). You mail the service member a written notice that the lawsuit has been filed, a copy of the complaint, two copies of a waiver form, and a prepaid return envelope. The request must give at least 30 days to respond, or 60 days if the defendant is outside the United States.4Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons
If the service member signs and returns the waiver, you file it and the case proceeds as though formal service occurred. They then have 60 days from the date the request was sent to answer, or 90 days if overseas. Signing a waiver does not surrender any objection to personal jurisdiction or venue. If a defendant located within the United States refuses to return the waiver without good cause, the court must impose the cost of formal service on them, including attorney fees for a motion to collect those costs.4Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons
For a military defendant, this route often works better than any other. It sidesteps base access entirely, it works whether the member is stateside or abroad, and it puts a cost consequence on refusal. If the waiver does not come back, every other method is still open to you.
Serving on a U.S. Military Installation
You cannot walk onto a base to hand someone papers. Security controls access, and each branch has its own regulations governing how civilian process is handled on federal property. Call the installation’s legal office before you do anything else.
Coordinating With the JAG Office
Contact the Judge Advocate General office or staff legal office. Under Army regulations, the staff judge advocate advises law enforcement on service-of-process situations, and the provost marshal’s office (military police) is typically the first contact for a civilian process server seeking base access.5eCFR. 32 CFR Part 516 – Litigation Navy installations follow a comparable procedure, with jurisdiction questions referred to the staff judge advocate or local naval legal service office.6eCFR. 32 CFR 720.20 – Service of Process Upon Personnel Other branches operate similarly.
Using a Civilian Process Server on Base
A hired process server can serve papers on base, but the server has to coordinate access through the installation. The commanding officer is not required to act as a process server. The installation will normally designate a location, such as the legal office, where the server and the service member can meet privately, away from the workplace.6eCFR. 32 CFR 720.20 – Service of Process Upon Personnel
Whether the member can refuse depends on jurisdiction. When the process comes from a court in the same state as the installation, the commander can direct the member to report to the designated location to meet the server. When the process comes from a court in another state, the service member is not required to accept it. They are told they may accept or refuse, and if they refuse the documents are returned to the server.6eCFR. 32 CFR 720.20 – Service of Process Upon Personnel On Army installations in areas of exclusive federal jurisdiction, the member is asked whether they accept voluntarily; if they decline, the requesting party is told federal jurisdiction precludes state service.5eCFR. 32 CFR Part 516 – Litigation
Service by Mail
Certified or registered mail with return receipt is sometimes an option, but whether it counts as valid service depends entirely on the rules of the court where you filed. Federal Rule of Civil Procedure 4(e) allows service under the law of the state where the district court sits or where service happens, and many states permit mail service for certain case types.4Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons If a service member refuses mail from out of state, the refusal is noted and the documents are returned.6eCFR. 32 CFR 720.20 – Service of Process Upon Personnel Check your court’s rules first, especially for divorce actions where many jurisdictions require personal delivery.
Serving a Service Member Overseas
International rules add another layer. The method depends on whether the host country has signed the Hague Service Convention and on the agreement governing the U.S. military presence there.
Hague Service Convention Countries
For signatory countries, you send a formal request to the host country’s designated Central Authority, which handles service under its own procedures. The request uses a standard form and must include copies of the documents. Most non-English-speaking countries require a translation into the official language, or at minimum a translated summary.7Hague Conference on Private International Law. Convention of 15 November 1965 on the Service Abroad of Judicial and Extrajudicial Documents in Civil or Commercial Matters The completed form and copies go directly to the Central Authority, with no transmittal letter required.8U.S. Department of Justice. Instructions on Serving Under the Hague Convention
Military cases carry an extra wrinkle. Status of Forces Agreements between the U.S. and the host country define the legal status of American military personnel and property on foreign soil, and can restrict foreign authorities’ access to U.S. installations. The Central Authority may not be able to physically serve papers on a U.S. base even after receiving a Hague request.9U.S. Department of State. Report on Status of Forces Agreements Coordinating with the installation’s JAG office or using a waiver under Rule 4(d) is usually more effective.
Non-Hague Countries and Letters Rogatory
If the country has not signed the Hague Convention, Federal Rule of Civil Procedure 4(f) still provides paths. A court can authorize service by a method prescribed by the foreign country’s law, through a letter rogatory (a formal request from the U.S. court to a foreign court asking for help), or by personal delivery or signed-receipt mail if the foreign country’s law does not prohibit it.4Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons Letters rogatory travel through the U.S. Department of State or directly between courts.10Office of the Law Revision Counsel. 28 USC 1781 – Transmittal of Letter Rogatory or Request The route is slow, dependent on diplomatic channels, and faces the same base-access limits as the Hague process.
For overseas members in either scenario, the Rule 4(d) waiver is often the practical choice. A letter to the member’s installation address asking them to accept the lawsuit voluntarily avoids foreign government involvement entirely, and the 60-day overseas response window accommodates military mail.
What Happens After Service: The SCRA Stay
Serving papers does not force the case forward on your schedule. The Servicemembers Civil Relief Act lets a properly served service member ask the court to pause the proceedings while military duties prevent them from appearing. The court must grant an initial stay of at least 90 days if the member submits two documents: a written statement explaining how current duties prevent them from appearing along with a date they expect to be available, and a letter from their commanding officer confirming that military duty prevents attendance and that leave has not been authorized.11Office of the Law Revision Counsel. 50 USC 3932 – Stay of Proceedings When Servicemember Has Notice
The 90 days is a floor. A member whose duties continue to interfere can apply for additional stays using the same documentation, and the court has discretion over whether to grant them. If the court refuses an additional stay, it must appoint an attorney to represent the service member going forward.11Office of the Law Revision Counsel. 50 USC 3932 – Stay of Proceedings When Servicemember Has Notice Expect a deployed defendant to receive at least one stay, and plan the litigation timeline around that.
The SCRA covers members of the Army, Navy, Air Force, Marine Corps, Space Force, and Coast Guard, commissioned officers of the Public Health Service and NOAA, and National Guard members called to active duty for more than 30 consecutive days under a presidential national emergency declaration.12Office of the Law Revision Counsel. 50 USC 3911 – Definitions Reservists who have received orders but have not yet reported also receive some protections.13United States Courts. Servicemembers Civil Relief Act The SCRA does not prevent you from suing any of them; it only shapes how the case moves.
