Who May Serve
Rule 4(c)(2) answers the question that arises once the plaintiff holds a complete set of papers: who may carry them to the defendant? Any person who is at least 18 years old and not a party may serve a summons and complaint.1 That sentence sets two independent conditions, one about the server's age and one about the server's place in the lawsuit. Rule 4 treats the server as one of several matters it regulates in detail, alongside the documents to be delivered, the manner and timing of delivery, and waiver.2 A delivery must satisfy both conditions, and a defendant who shows that it did not may challenge the service as insufficient under Rule 12(b)(5).3
The rule makes more sense once you see what it replaced. Before 1983 the marshal normally served the summons and complaint, and the principal purpose of the 1983 amendments was to end that practice.4 The Marshals Service's appropriations had been reduced, so the amendments relieved marshals of the duty of serving papers in private civil litigation. Since then a marshal will not ordinarily make service, and any person who is not a party and is at least 18 may.5 The plaintiff's lawyer could deliver the papers herself, but more likely she will hire a private process server or a sheriff or deputy authorized to serve process.6
Opening the field of servers does not shift the plaintiff's duty. The plaintiff remains responsible for having the summons and a copy of the complaint served within the time Rule 4(m) allows, and she must furnish the necessary copies to whoever makes service.7 Yet she does not serve the papers herself.8 She owns the task but may not perform it, so a server who fails to deliver leaves the consequences with her. This unit takes the two conditions in order, party status first and then age, and then turns to the one setting in which the court itself chooses the server: service by a marshal or a court appointee.9
The Non-Party Requirement
A party to the action may not serve the summons and complaint, however proper the rest of the delivery. Marvell, a plaintiff proceeding pro se, shows how the bar operates. He has the right documents, and he hands them to Donne in person, a method Rule 4(e)(2)(A) authorizes. But Marvell is a party, and Rule 4(c)(2) bars him from serving the summons and complaint himself.10 The method was sound and the server was not. A fact pattern that describes flawless in-hand delivery should still be read for the identity of the person holding the papers.
The test is status in the lawsuit and nothing broader. Employment by the plaintiff, kinship, and friendship do not disqualify a person who is not a party, so the plaintiff may use a process server, a sheriff or deputy, a paralegal, or an adult friend.11
The sources offer several reasons for keeping the parties out of the delivery. A party who confronts an adversary with the papers risks a physical confrontation.12 A hand-off between the parties might also lead to an immediate but distinctly nonjudicial settlement of their differences.13 Both explanations are offered tentatively, with a "perhaps." A third reason concerns proof of delivery. A sheriff or constable is a neutral person with a professional reputation to protect, so his or her certification that service was made is more trustworthy than that of a party or someone working for a party.14 A party who served personally would be vouching for the success of his own lawsuit. The rule does not carry that logic to its end, because a non-party who works for the plaintiff may still serve, and the text draws its line at party status.
The bar is a prudential limit that Rule 4 imposes. Nothing in Mullane suggests that it is constitutionally required.15 A defendant who objects to service by a party therefore stands on the text of Rule 4, through a Rule 12(b)(5) motion, and does not need to claim that the papers failed to give notice.16
The lawyer who represents a party presents a closer-looking case. Counsel is not herself a party to the action, so service by counsel is permissible.17 It is nonetheless poor practice. If service is later disputed, the lawyer who made it may be called to testify about the delivery, which is why process servers or paralegals typically do the work.18
The Age Requirement
The server must also be at least 18 years old.20 The line is a number, not a judgment about maturity or experience. A 17-year-old fails and an 18-year-old qualifies, however capable either appears, so a court applying Rule 4(c)(2) asks one factual question about the server's age.
The age condition stands apart from the party condition. A server can satisfy one and fail the other, and the defendant needs to show only a single failure. Private service is now the default, and the rule's text screens servers by age and party status alone.21
The nephew's defect is one the defendant can raise by a motion for insufficient service of process under Rule 12(b)(5).22 The method, the documents, and the server's non-party status were all correct, so the age of the person holding the papers decided the result.
A second age standard appears elsewhere in Rule 4, and students often merge it with the first. Service on an individual at the individual's dwelling must be made on a person of "suitable age and discretion."23 That standard describes the recipient, the person who answers the door, and has nothing to do with who delivers the papers. It sets no number and does not require an adult. It asks whether the person is mature enough to understand that the papers matter and must be passed along to the defendant.24 In Universal Property & Casualty Insurance Co. v. Melendez-Grant (D.S.C. 2013), a federal district court approved service on the defendant's 11-year-old son. In Metropolitan Life Insurance Co. v. Hunter (E.D. Va. 2013), another found service on a defendant's 16-year-old son proper.25 Neither decision says anything about whether a minor may serve. The server's qualification is categorical, while the recipient's is functional: the question is whether this particular person can be trusted to pass the papers on.
A fact pattern that mentions a teenager therefore asks one of two questions, depending on where the teenager stands. A teenager answering the door raises the recipient standard, which is flexible and judged on maturity. A teenager carrying the papers raises the server requirement, which is a fixed floor of 18.
Marshals and Court Appointees
Rule 4(c)(3) governs the one situation in which a federal judge helps choose who delivers the papers. At the plaintiff's request, the court may order that service be made by a United States marshal or deputy marshal or by a person the court specially appoints. The court must so order if the plaintiff is authorized to proceed in forma pauperis under 28 U.S.C. § 1915 or as a seaman under 28 U.S.C. § 1916.27 A plaintiff who proceeds in forma pauperis, Latin for in the manner of a pauper, is one the court has permitted to sue without paying the usual costs of litigation. The single sentence therefore carries two commands, and the verb decides which governs: discretion for the ordinary plaintiff, obligation for the two named groups. An order under this provision changes only the identity of the server. The summons still must be served with the complaint, and the plaintiff still answers for the timing.28
The discretionary half follows from the default that Rule 4(c)(2) set. Since the 1983 amendments a marshal will not ordinarily make service in private civil litigation, because the marshals were relieved of that work when the Marshals Service's appropriations shrank.29 A paying plaintiff can hire a process server, so a request for a marshal asks the court to spend a scarce federal resource on a task that private parties already perform. The rule leaves the choice to the judge, who can grant the request when the circumstances call for official help and refuse it when the request rests on convenience alone.
The mandatory half works differently. The rule gives no reason for it, but the effect is plain: for a plaintiff authorized to proceed in forma pauperis or as a seaman, the court, not the plaintiff, arranges who delivers the papers. The trigger is authorization under the statute. A plaintiff who has only said she cannot afford a server, without authorization under § 1915, falls outside the command.
A fact pattern that mentions a marshal therefore asks two questions in order: does the plaintiff hold the status that makes the order mandatory, and, if not, has the court chosen to exercise its discretion? Treating marshal service as the federal default carries over the practice before 1983, when the marshal normally served the summons and complaint.30 Treating every plaintiff's request as binding on the court overlooks the word may.
