To serve someone court papers, you arrange for a neutral adult to deliver the summons and complaint to the defendant, then file proof with the court that the delivery happened. You cannot hand-deliver your own papers. Under federal rules, the server must be at least 18 and not a party to the case, and you have 90 days from the date you filed your complaint to get it done.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons State court deadlines vary but the basic structure is the same.
Who Can Deliver the Papers
Federal Rule of Civil Procedure 4(c)(2) sets two rules for anyone who serves a summons and complaint: at least 18 years old, and not a party to the lawsuit.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons That disqualifies the plaintiff, any co-plaintiffs, and any co-defendants. Most state courts apply the same principle with local variations.
In practice, you have three choices.
- The local sheriff or marshal. Most counties will serve papers for a fee, typically $25 to $100. It carries built-in credibility with courts, though scheduling can be slow if the office is backlogged.
- A professional process server. Private servers specialize in finding people and getting documents delivered, generally $20 to $100 per job, more for hard-to-find defendants or rush work. Some states require servers to be licensed or certified; others let anyone who meets the age and neutrality rules do it.
- Any eligible adult you know. A friend, neighbor, or coworker who is 18 or older and has no stake in the case can serve papers for free. The trade-off is that inexperienced servers make more procedural mistakes, and opposing lawyers sometimes challenge service performed by non-professionals.
What Gets Delivered
Two documents form the core of the delivery: the summons and the complaint. The summons is a court-issued notice telling the defendant they are being sued, naming the court, and giving a response deadline. In federal court, that deadline is 21 days from the date of service.2United States Courts. AO 440 – Summons in a Civil Action The complaint is what you drafted explaining what the defendant did, why it harmed you, and what you want the court to do. Both must be served together.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons
You also need a proof of service form, sometimes called an affidavit of service or return of service. It is not handed to the defendant. The server fills it out after delivery and you file it with the court. Have this form ready before your server heads out so they can complete it immediately, while every detail is still fresh.
Ask for a Waiver First
Before paying for formal service, federal rules give you a cheaper path. Under Rule 4(d), you mail the defendant a copy of the complaint along with two copies of a waiver form and a prepaid return envelope. The notice has to explain what happens if the defendant accepts or refuses, name the court, and state the date it was sent.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons
The defendant gets at least 30 days to return the signed waiver, or 60 days if they are outside the United States. The incentive to cooperate is more time to answer: a defendant who waives service gets 60 days to respond instead of 21. The penalty for refusing without good cause is cost-shifting. A defendant inside the United States who ignores the waiver request must pay the expenses of formal service, including attorney’s fees for any motion needed to collect those costs.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons
When the signed waiver comes back, you file it with the court. That filing replaces formal service and proof of service altogether. The approach works well when the defendant is a known business or someone whose address you have. It will not help with a defendant who is hiding or uncooperative, and not every state court offers a comparable procedure.
How the Delivery Can Happen
When formal service is necessary, courts recognize several methods. Federal Rule 4(e) covers service on an individual within the United States, and state rules generally follow the same framework with local variations.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons
Personal Service
The server physically hands the summons and complaint to the defendant. Courts prefer this because it leaves the least room for the defendant to argue they never got the papers. The server does not need cooperation. In most jurisdictions, placing the papers in the defendant’s hand or at their feet after identifying them is enough, even if the defendant refuses to take them.
Substituted Service
When the defendant is not home or cannot be reached directly, federal rules allow the server to leave copies at the defendant’s home with someone of “suitable age and discretion” who lives there, usually another adult in the household.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons Papers can also be left with an authorized agent.3Legal Information Institute. Substituted Service Many state rules add a mailing requirement on top of the drop-off: after leaving the papers, the server must also send a copy by first-class mail to the same address. Some states call it “nail and mail” service when papers are posted to the door itself rather than handed to a person. Check your local rules carefully, because skipping the mailing step can invalidate the entire service.
Service by Mail
Many state courts allow service by certified or registered mail with a return receipt requested. The signed receipt proves someone at the defendant’s address accepted the package. This method is common in small claims cases and for out-of-state defendants. Federal courts do not list mail as a standalone method under Rule 4(e)(2), but Rule 4(e)(1) allows you to follow state law, so mailing is available in federal court whenever it would work under the law of the state where the court sits or where the defendant is located.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons If the mail goes unclaimed or the defendant refuses to sign, service fails and you have to try again.
Serving a Business Instead of a Person
Suing a company means serving the right person inside it. Under Federal Rule 4(h), a corporation, partnership, or unincorporated association can be served by delivering the summons and complaint to an officer, a managing or general agent, or any agent the company has authorized to accept legal papers.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons You can also use any method that would work to serve an individual under state law.
Every state requires registered businesses to designate a registered agent whose job is to accept legal documents. To find one, search the business entity database maintained by the secretary of state where the company is registered. These databases are free and online in every state. You get the agent’s name and address, and that is all your server needs. Handing papers to a random employee at a front desk is risky. Unless that person is an officer or authorized agent, the defendant can argue the service was defective.
Filing Proof of Service
After the delivery, the server fills out the proof of service form documenting what happened: the name of the person served, the date and time, the address, and the method used. The server signs under penalty of perjury, and some jurisdictions require notarization.
Filing this form with the court clerk is what puts service on record. Until that form is on file, the court has no evidence the defendant was notified and the case will not move forward. Filing also starts the clock on the defendant’s deadline to respond. If you used a waiver instead, filing the signed waiver replaces the proof of service requirement.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons
The 90-Day Deadline
Federal courts give you 90 days from the date you file your complaint to serve the defendant. Miss that deadline and the court must dismiss the case without prejudice unless you can show good cause for the delay.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons Refiling is allowed, but that is cold comfort when the statute of limitations is running. If the filing deadline for your type of claim expires while you scramble to re-serve, you lose the right to sue at all. This is where cases quietly die.
State courts set their own deadlines, and they range widely. Some give 60 days, others 120, and a few leave it to the judge. Whatever the deadline is in your jurisdiction, put it on a calendar the day you file. If you are running up against it and still have not served the defendant, file a motion asking for an extension before the deadline passes. Judges are far more sympathetic to a plaintiff who asks in advance than one who shows up after the deadline with excuses.
When the Defendant Is Hard to Find
Some defendants move without leaving a forwarding address, use fake names, or actively dodge the server. Before a court will authorize any alternative method, you have to show “due diligence,” which means a documented trail of serious attempts to locate and serve the person through standard methods. A single failed visit to an old address will not cut it. Courts want multiple attempts at different times, searches of public records, and any other reasonable steps.
Professional process servers sometimes use skip tracing to locate evasive defendants, searching public records, property ownership databases, DMV records, social media, and other data sources to find a current address. Skip tracers must comply with federal privacy laws, and their findings can support the due diligence showing you eventually make to the court.
Service by Publication
When every standard method has been exhausted and the defendant’s location is still unknown, a court may authorize service by publication. That means running a legal notice in a newspaper of general circulation in the area where the defendant was last known to live. Courts are reluctant to approve this because a newspaper ad may never reach the defendant.4Legal Information Institute. Service by Publication You will need a court order, and the judge will typically want an affidavit detailing every failed attempt at personal or substituted service.
Electronic Service
Courts have increasingly authorized service through email, social media, and other digital channels when traditional methods fail. Federal courts have approved service by email in cases where the defendant conducted business online and could not be reached physically, and at least one court has authorized service via Twitter where the platform was reasonably calculated to give actual notice. These orders are the exception, not the rule. You need a court order, and judges typically want electronic service combined with another method, like publication, rather than standing alone.
The Military Status Check Before Any Default
One boundary worth knowing before you get near a default judgment: the Servicemembers Civil Relief Act. Before a court can enter any default judgment, the plaintiff must file an affidavit stating whether the defendant is in military service. If you do not know, you must say so.5Office of the Law Revision Counsel. 50 USC 3931 – Protection of Servicemembers Against Default Judgments You can check military status through the Department of Defense Manpower Data Center.
If the defendant is in military service, the court must appoint an attorney to represent them before entering judgment. If military status cannot be determined from the affidavits, the judge can require the plaintiff to post a bond to protect the servicemember against losses if the judgment is later set aside. Filing a false affidavit about military status is a federal crime punishable by up to one year in prison.5Office of the Law Revision Counsel. 50 USC 3931 – Protection of Servicemembers Against Default Judgments Skipping this step does not just risk your judgment being overturned. It puts you on the wrong side of federal law.
