(d) Methods of service. The summons and complaint may be served in any state or judicial district of the United States. Unless service is accepted, service of the summons and complaint must be by one of the following methods:
(1) Personal service. The summons and complaint may be served by any person 18 years of age or older at the time of service and not a party to the action or a party’s attorney. If the person to be served refuses to accept a copy of the summons and complaint, service is sufficient if the person serving them states the name of the process and offers to deliver them. Personal service must be made as follows:
(A) Upon any individual other than one covered by paragraphs (d)(1)(B), (d)(1)(C) or (d)(1)(D), by delivering a copy of the summons and complaint to the individual personally, or by leaving them at the individual’s dwelling house or usual place of abode with a person of suitable age and discretion who resides there, or by delivering them to an agent authorized by appointment or by law to receive process;
(B) Upon a minor under 14 years old by delivering a copy of the summons and complaint to a parent or guardian of the minor or, if none can be found within the state, then to any person having the care and control of the minor, or with whom the minor resides, or by whom the minor is employed;
(C) Upon an individual judicially declared to be incapacitated, of unsound mind, or incapable of conducting the individual’s own affairs, by delivering a copy of the summons and complaint to the individual and to the guardian or conservator of the individual if one has been appointed; the individual’s legal representative if one has been appointed, and, in the absence of a guardian, conservator, or legal representative, to the person, if any, who has care, custody, or control of the individual;
(D) Upon an individual incarcerated or committed at a facility operated by the state or any of its political subdivisions, by delivering a copy of the summons and complaint to the individual personally, to the person who has the care, custody, or control of the individual, or to that person’s designee or to the guardian or conservator of the individual if one has been appointed. The person to whom the summons and complaint are delivered must promptly deliver them to the individual;
(E) Upon a corporation not otherwise provided for in this rule, a limited liability company, a partnership, or an unincorporated association subject to suit under a common name, by delivering a copy of the summons and complaint to an officer, a managing or general agent, or other agent authorized by appointment or law to receive process and by also mailing a copy of the summons and complaint to the defendant, if the agent is one authorized by statute to receive process and the statute so requires. If no officer or agent can be found within the state, and the defendant has, or advertises or holds itself out as having, a place of business within the state or elsewhere, or does business within this state or elsewhere, then upon the person in charge of the place of business;
(F) Upon an incorporated city or town, by delivering a copy of the summons and complaint as required by statute, or in the absence of a controlling statute, to the recorder;
(G) Upon a county, by delivering a copy of the summons and complaint as required by statute, or in the absence of a controlling statute, to the county clerk;
(H) Upon a school district or board of education, by delivering a copy of the summons and complaint as required by statute, or in the absence of a controlling statute, to the superintendent or administrator of the board;
(I) Upon an irrigation or drainage district, by delivering a copy of the summons and complaint as required by statute, or in the absence of a controlling statute, to the president or secretary of its board;
(J) Upon the state of Utah or its department or agency by delivering a copy of the summons and complaint to the attorney general and any other person or agency required by statute to be served; and
(K) Upon a public board, commission or body by delivering a copy of the summons and complaint as required by statute, or in the absence of a controlling statute, to any member of its governing board, or to its executive employee or secretary.
(2) Service by mail or commercial courier service.
(A) The summons and complaint may be served upon an individual other than one covered by paragraphs (d)(1)(B) or (d)(1)(C) by mail or commercial courier service in any state or judicial district of the United States provided the defendant signs a document indicating receipt.
(B) The summons and complaint may be served upon an entity covered by paragraphs (d)(1)(E) through (d)(1)(I) by mail or commercial courier service in any state or judicial district of the United States provided defendant’s agent authorized by appointment or by law to receive service of process signs a document indicating receipt.
(C) Service by mail or commercial courier service shall be complete on the date the receipt is signed as provided by this rule.
(3) Acceptance of service.
(A) Duty to avoid expenses. All parties have a duty to avoid unnecessary expenses of serving the summons and complaint.
(B) Acceptance of service by party. Unless the person to be served is a minor under 14 years old or an individual judicially declared to be incapacitated, of unsound mind, or incapable of conducting the individual’s own affairs, a party may accept service of a summons and complaint by signing a document that acknowledges receipt of the summons and complaint.
(i) Content of proof of electronic acceptance. If acceptance is obtained electronically, the proof of acceptance must demonstrate on its face that the electronic signature is attributable to the party accepting service and was voluntarily executed by the party. The proof of acceptance must demonstrate that the party received readable copies of the summons and complaint prior to signing the acceptance of service.
(ii) Duty to avoid deception. A request to accept service must not be deceptive, including stating or implying that the request to accept service originates with a public servant, peace officer, court, or official government agency. A violation of this paragraph may nullify the acceptance of service and could subject the person to criminal penalties under applicable Utah law.
(C) Acceptance of service by attorney for party. An attorney may accept service of a summons and complaint on behalf of the attorney’s client by signing a document that acknowledges receipt of the summons and complaint.
(D) Effect of acceptance, proof of acceptance. A person who accepts service of the summons and complaint retains all defenses and objections, except for adequacy of service. Service is effective on the date of the acceptance. Filing the acceptance of service with the court constitutes proof of service under Rule 4(e).
(4) Service in a foreign country. Service in a foreign country must be made as follows:
(A) by any internationally agreed means reasonably calculated to give notice, such as those means authorized by the Hague Convention on the Service Abroad of Judicial and Extrajudicial Documents;
(B) if there is no internationally agreed means of service or the applicable international agreement allows other means of service, provided that service is reasonably calculated to give notice:
(i) in the manner prescribed by the law of the foreign country for service in that country in an action in any of its courts of general jurisdiction;
(ii) as directed by the foreign authority in response to a letter of request issued by the court; or
(iii) unless prohibited by the law of the foreign country, by delivering a copy of the summons and complaint to the individual personally or by any form of mail requiring a signed receipt, addressed and dispatched by the clerk of the court to the party to be served; or
(C) by other means not prohibited by international agreement as may be directed by the court.
(5) Other service.
(A) If the identity or whereabouts of the person to be served are unknown and cannot be ascertained through reasonable diligence, if service upon all of the individual parties is impracticable under the circumstances, or if there is good cause to believe that the person to be served is avoiding service, the party seeking service may file a motion to allow service by some other means. An affidavit or declaration supporting the motion must set forth the efforts made to identify, locate, and serve the party, or the circumstances that make it impracticable to serve all of the individual parties.
(B) If the motion is granted, the court will order service of the complaint and summons by means reasonably calculated, under all the circumstances, to apprise the named parties of the action. The court’s order must specify the content of the process to be served and the event upon which service is complete. Unless service is by publication, a copy of the court’s order must be served with the process specified by the court.
(C) If the summons is required to be published, the court, upon the request of the party applying for service by other means, must designate a newspaper of general circulation in the county in which publication is required.
(e) Proof of service.
(1) The person effecting service must file proof of service stating the date, place, and manner of service, including a copy of the summons. If service is made by a person other than by an attorney, sheriff, constable, United States Marshal, or by the sheriff’s, constable’s or marshal’s deputy, the proof of service must be by affidavit or unsworn declaration as described in Title 78B, Chapter 18a, Uniform Unsworn Declarations Act.
(2) Proof of service in a foreign country must be made as prescribed in these rules for service within this state, or by the law of the foreign country, or by order of the court.
(3) When service is made pursuant to paragraph (d)(4)(C), proof of service must include a receipt signed by the addressee or other evidence of delivery to the addressee satisfactory to the court.
(4) Failure to file proof of service does not affect the validity of the service. The court may allow proof of service to be amended.

Plain-English Summary

Rule 4 is the mechanics manual for getting a defendant properly notified of a lawsuit. The summons must be signed and issued by the plaintiff or the plaintiff's attorney, and Rule 4(b) sets the outside clock: unless service is accepted, the summons and complaint must be served no later than 120 days after the complaint is filed, unless the court orders a different period under Rule 6. Miss that window, and the action against the unserved defendant can be dismissed without prejudice, either on a party's motion or on the court's own initiative.

Rule 4(c) spells out what a summons must say — the court's name and address, the parties' names, the county, the defendant's obligation to answer, the deadline for doing so, a warning that a default judgment can follow a failure to answer, whether the complaint is already on file or will be within ten days, and a bilingual notice in the court-approved form. If the case was commenced by service rather than filing, the summons must also tell the defendant that no answer is required if the complaint is not filed within ten days, and must give a phone number the defendant can call, no sooner than 14 days after service, to check whether the complaint has been filed.

Rule 4(d) lists the methods for delivering the summons and complaint. Personal service — by anyone 18 or older who is not a party or a party's attorney — has separate delivery rules depending on who is being served: individuals generally, minors under 14 (served through a parent or guardian), individuals judicially declared incapacitated, incarcerated individuals, corporations and similar entities, and various government bodies such as cities, counties, school districts, and the state itself through the attorney general. Service can also be made by mail or commercial courier if the recipient signs a document acknowledging receipt, or a party or their attorney can accept service instead by signing an acknowledgment — a path the rule encourages by imposing a duty on all parties to avoid the unnecessary expense of formal service, while also barring deceptive tactics in requesting acceptance. For defendants abroad, the rule looks first to internationally agreed methods such as the Hague Convention, then to other means reasonably calculated to give notice. And when a defendant's identity or location cannot be found despite reasonable diligence, or the defendant appears to be avoiding service, a party can ask the court by motion, supported by an affidavit or declaration describing the efforts made, to approve some other means of service.

Finally, Rule 4(e) requires the person who served the summons and complaint to file proof of service stating the date, place, and manner of service. Anyone other than an attorney, sheriff, marshal, or their deputies must submit that proof by affidavit or unsworn declaration. Failing to file proof of service does not undo the service itself — the court may allow the proof to be filed or amended later.

Frequently Asked Questions

How long do I have to serve a defendant after filing a complaint in Utah?

120 days from the date the complaint is filed, unless service is accepted or the court orders a different period under Rule 6. If service isn't timely made, the action against that defendant can be dismissed without prejudice.

Who is allowed to serve a summons and complaint?

Any person 18 or older who is not a party to the action and not a party's attorney, subject to the specific delivery requirements for the type of defendant being served.

How do I serve a corporation or LLC in Utah?

By delivering a copy of the summons and complaint to an officer, a managing or general agent, or another agent authorized by appointment or law to receive process, and also mailing a copy if a statute authorizing the agent requires that. If no such officer or agent can be found in the state, service can be made on the person in charge of the defendant's place of business.

Can a defendant just accept service instead of being formally served?

Yes, in most cases. A party (other than a minor under 14 or a judicially incapacitated individual) or their attorney can accept service by signing a document acknowledging receipt. Accepting service preserves all other defenses except a challenge to the adequacy of service itself.

What if I can't find or identify the person I need to serve?

Rule 4(d)(5) allows a party to move the court for permission to use another method of service, supported by an affidavit or declaration describing the efforts made to identify, locate, or serve the person, or explaining why serving all individual parties is impracticable.

How is a defendant served in a foreign country?

Primarily through any internationally agreed method reasonably calculated to give notice, such as those under the Hague Convention. If no such agreement applies or it permits other means, service can follow the foreign country's own law, a letter of request to a foreign authority, personal delivery, or signed-receipt mail, or another method the court directs.

What happens if proof of service is never filed?

The service itself remains valid — failing to file proof of service does not affect its validity. The court may allow the proof of service to be filed or amended after the fact.
