In Utah, you can still get divorced if your spouse disappears, but only after proving you made a diligent search and using court-approved alternative service of process methods. Missing spouse divorce cases require strict compliance with Utah Rules of Civil Procedure 4, and courts will not simply rubber-stamp a request for judgment by default.
It is not unusual in Utah divorce cases for one spouse to “disappear.” Sometimes it is intentional: a spouse does not want to be found because he/she is afraid of paying child support or alimony, or because he/she wants to delay the inevitable property division. Sometimes it is just being a flake—someone moving without telling anyone where he/she went and leaving no means of future contact. Regardless of the motive, a missing spouse creates legal problems, one of which is: you cannot just skip over the requirement of notice and get divorced.
The law in Utah requires that the respondent be served with a copy of the divorce petition and summons (this is known as “service of process”) before the court can exercise jurisdiction. Without valid service, the case goes nowhere.
Why Service of Process Matters
Utah Rule of Civil Procedure 4 governs service of process. It requires that a petition and summons be personally served on the respondent. This is not a technicality—it is a constitutional due process requirement. Before the government can order rights in marital (and even pre-marital) property, enter child custody orders, or impose support obligations, the affected person must be given notice and an opportunity to be heard. That is why Utah courts will not let you simply declare your spouse “missing” and move forward.
Proving “Reasonable Diligence”
What if you cannot find your spouse? Utah law allows for “alternative service,” but only if you first demonstrate that you exercised “reasonable diligence” in trying to locate him/her to serve him/her personally.
Reasonable diligence means more than checking one address and giving up. Courts expect you to check last known residences, talk to friends and family members, ask employers, and search social media.
Utah appellate courts have emphasized that diligence is not optional. In Jackson Constr. Co. v. Marrs, 2004 UT 89, the Utah Supreme Court explained that a party must strictly comply with diligence requirements before the court can authorize alternative service. In that case, the Court stressed that minimal effort is not enough—the petitioner must show genuine, diligent, documented effort to locate the missing party.
Alternative Service Options
If the court is satisfied that you made duly diligent efforts to locate the party you are trying to serve, you can move for an order permitting alternative service under Utah Rule of Civil Procedure 4(d)(5). Alternative service may include mailing documents to the last known address, sending notice by email or social media, or even publishing the summons in a newspaper (service by publication in a newspaper was a lot more popular when people read newspapers).
Moving Forward Without the Missing Spouse
If alternative service is approved and your spouse still does not respond, you can request a default judgment under Utah Rule of Civil Procedure 55. At this stage, many people assume the court will simply give them whatever they asked for in their petition. That assumption is incorrect.
Even when a spouse defaults, the court still has to ensure that custody, property, and support orders comply with Utah law and that what is sought is equitable. Custody must be decided based on the “best interest of the child” standard under Utah Code § 81-9-204. Property and debt must be divided equitably under Utah Code § 81-4-406. Judges are reluctant to award everything to the appearing spouse simply because the other side is absent. Expect scrutiny.
Risks of Cutting Corners
If you did not exercise true diligence before obtaining alternative service, your missing spouse can later challenge the judgment. Utah Rules of Civil Procedure 55(c) and/or 60(b)(4) allows a party to move to set aside a judgment if notice was defective. That can mean years of delay and additional litigation.
Disappearing does not mean a spouse loses all rights permanently. Courts take defaults seriously, but they also scrutinize them carefully.
A missing spouse complicates a Utah divorce but does not make it impossible.
The petitioner must follow Rule 4, document all efforts to locate the respondent, and be prepared for the reality that default does not guarantee everything requested will be granted. Courts demand fairness, even when one spouse is absent.
