How to Serve Small Claims Papers in Utah
Short answer: In Utah small claims cases, the affidavit and summons must be served on the defendant by a sheriff, constable, or process server — or by the defendant agreeing to accept service — at least 30 calendar days before your trial date. You then have to file proof of service with the court within 10 business days of serving them.
Who this guide is for
Anyone who has filed a Utah small claims case (or is about to) and needs to understand how to legally notify the defendant that they've been sued. Filing your affidavit isn't enough on its own — the case can't move forward until the defendant has been properly served.
Who can serve the papers
- A sheriff, constable, or deputy
- A U.S. Marshal's deputy
- A private process server
- The defendant directly, if they agree to accept service — in that case, you can deliver the documents by any method you both agree to
You (the plaintiff) generally cannot personally hand the papers to the defendant yourself in a way that counts as valid service — use one of the methods above.
Timing
- The affidavit and summons must be served at least 30 calendar days before the trial date.
- Service follows Utah Rule of Civil Procedure 4.
- Proof of service must be filed with the court no later than 10 business days after service is completed.
Missing either deadline can delay or jeopardize your case, so build in buffer time — don't wait until the last week before trial to attempt service.
Serving documents other than the affidavit and summons
Once the case is underway, other papers (not the original affidavit and summons) can generally be served by first-class mail to the other party's last known address — a simpler standard than the requirements for that first, critical notice.
What happens if you can't serve the defendant
If the defendant is avoiding service or you can't locate them, talk to the court clerk or Utah Courts' Self-Help Center about your options — this is exactly the kind of situation where a quick question to the Self-Help Center (selfhelp@utcourts.gov, text 801-742-1898, or 888-683-0009) can save you from an avoidable procedural mistake.
Common mistakes
- Trying to serve the papers yourself informally — e.g., mailing them yourself or leaving them at the defendant's home without using an authorized method.
- Serving too close to the trial date, leaving no room to fix a problem if the first attempt fails.
- Forgetting to file proof of service — even if you served the defendant correctly, the court needs the paperwork showing it happened.
Frequently asked questions
Can I serve the papers on the defendant myself? Not by personally handing them over — you can arrange for the defendant to accept service by agreement, or use a sheriff, constable, or process server.
What if the defendant refuses to accept the papers? A sheriff, constable, or process server can generally still complete valid service even if the defendant is uncooperative — this is part of why using an authorized server matters. Talk to your process server or the court if this happens.
Does service cost money? Yes — sheriffs, constables, and process servers generally charge a fee for service, separate from your court filing fee.
