Process Serving in Utah

Utah’s District Court is the state trial court of general jurisdiction, with original jurisdiction to try all civil cases. Justice Courts, established by counties and municipalities, handle small claims and certain minor offenses within their boundaries. Civil service of process is governed by Rule 4 of the Utah Rules of Civil Procedure, which covers the summons, the 120-day service deadline, the methods of service on individuals, businesses and public bodies, acceptance of service, court-ordered alternative service and proof of service. The Process Server Act, Utah Code § 78B-8-302, amended effective September 1, 2026, sets who may serve a complaint, summons or subpoena and who may serve other court process.

Under Utah Code § 78B-8-302(2), a complaint, a summons or a subpoena may be served by an individual who is 18 or older at the time of service and is not a party to the action or a party’s attorney. Rule 4(d)(1) states the same requirement for personal service of the summons and complaint, and Utah’s courts remind parties that they cannot serve the papers themselves. The statute sets no licence requirement for this kind of service.

Other process issued by Utah courts is more limited. Under § 78B-8-302(3), all process may be served by a peace officer acting within the scope of employment, a sheriff or appointed deputy, a constable or deputy (who must be licensed under the Constables Licensing Act beginning January 1, 2027), a state investigator authorized to serve civil process, or a private investigator agent, registrant or apprentice licensed under the Private Investigation Licensing Act. A licensed private investigator serving process must tell the person served that the investigator is acting as a process server and print the investigator’s name and licence number on the first page of each document served. Some law enforcement and special function officers may serve only when force is authorized on the face of the document or a breach of the peace is imminent or likely (§ 78B-8-302(6)).

Rule 4(d)(1)(A) allows personal delivery to the individual, leaving the summons and complaint at the individual’s dwelling house or usual place of abode with a person of suitable age and discretion who resides there, or delivery to an agent authorized by appointment or law to receive process. If the person refuses the papers, service is sufficient if the server states the name of the process and offers to deliver it. Corporations, LLCs, partnerships and unincorporated associations are served through an officer, a managing or general agent, or another agent authorized by appointment or law, with any mailing a statute requires; if no officer or agent can be found in Utah, through the person in charge of a place of business (Rule 4(d)(1)(E)). Cities, counties, school districts, the State and other public bodies are served as the statute directs or on the officials Rule 4 lists.

Service by mail or commercial courier is valid only if the defendant, or an entity’s authorized agent, signs a document indicating receipt (Rule 4(d)(2)). A party or the party’s attorney may accept service in writing (Rule 4(d)(3)). If the defendant cannot be found with reasonable diligence or is avoiding service, the court may order another method, including publication in a designated newspaper (Rule 4(d)(5)).

Unless the summons and complaint are accepted, they must be served no later than 120 days after the complaint is filed, unless the court orders a different period under Rule 6. If they are not timely served, the action against the unserved defendant may be dismissed without prejudice on motion of any party or on the court’s own initiative (Utah R. Civ. P. 4(b)).

Unless a statute or court order provides otherwise, a defendant must file and serve an answer within 21 days after service of the summons and complaint within Utah, and within 30 days after service outside the state (Rule 12(a)). Utah’s court self-help page applies the same 21- and 30-day periods after a signed acceptance of service, and three days in eviction cases. Mail or courier service is complete on the date the receipt is signed, acceptance of service is effective on the date of acceptance, and an order for alternative service specifies the event on which service is complete (Rule 4(d)). When an action is begun by serving the summons before the complaint is filed, the summons must state that the complaint will be filed within 10 days after service (Rule 4(c)).

The server of a summons, complaint or subpoena must be at least 18 and must not be a party or a party’s attorney (Utah Code § 78B-8-302(2); Rule 4(d)(1)). Under § 78B-8-302(7), an individual convicted of a felony offense that would make the individual a sex offender under § 53-29-202(2)(b), and an individual who is the respondent in a protective-order proceeding in which a protective order was granted, may not serve process issued by a court. Licensed private investigators may not make an arrest under a bench warrant (§ 78B-8-302(4)).

Rule 4 has special methods for minors under 14 (service on a parent or guardian), individuals judicially declared incapacitated (service on the individual and the guardian or conservator), and people held in state or local facilities (delivery through the person with custody, who must promptly pass the papers on). A request to accept service must not be deceptive, including by implying that it comes from a court or public official (Rule 4(d)(3)(B)(ii)). Neither Rule 4 nor § 78B-8-302 addresses Sunday or holiday service, and the sources cited here do not establish a Sunday prohibition.

The person effecting service must file proof of service stating the date, place and manner of service, including a copy of the summons. When service is made by anyone other than an attorney, sheriff, constable, U.S. Marshal or their deputies, the proof must be an affidavit or an unsworn declaration under the Uniform Unsworn Declarations Act, Title 78B, Chapter 18a (Rule 4(e)(1)), so a compliant declaration needs no notary. Utah Code § 78B-8-302(8) also requires every server to document legibly the date and time of service on the front page of the document served, print the server’s name, address and telephone number on the return, and sign the return in substantial compliance with the Unsworn Declarations Act. Officers add a badge number, constables add the details required for constables, and private investigators add their identification number.

Filing a signed acceptance of service is itself proof of service (Rule 4(d)(3)(D)). Failure to file proof does not affect the validity of service, and the court may allow the proof to be amended (Rule 4(e)(4)). Utah’s courts advise filing the Proof of Service together with a copy of the summons.
