Idaho Small Claims Court Rules — What Every Filer Needs to Know

Idaho small claims cases run under a separate rulebook from regular civil court, and the differences trip up filers who assume the standard process applies. The Idaho Rules for Small Claims Actions (I.R.S.C.A.), issued by the Idaho Supreme Court, govern everything from who can appear to how evidence gets presented. Here are the rules that actually matter when you're filing or defending a claim.

The $15,000 Jurisdictional Limit

Senate Bill 1330, effective July 1, 2026, raised the small claims ceiling from $5,000 to $15,000 under Idaho Code § 1-2301. That limit covers claims for money owed or the return of specific personal property. If your claim exceeds $15,000, you can still file in small claims, but you must waive everything above the cap in your complaint — and you cannot split a single debt into multiple lawsuits to stay under the line.

Claims for injunctions, specific performance, or punitive damages fall outside small claims jurisdiction entirely. Those go to the standard Magistrate Division or District Court.

No Attorneys in the Courtroom

Idaho Code § 1-2308 bans attorneys from representing parties during a small claims trial. You can hire a lawyer to help you prepare your paperwork or review your evidence beforehand, but no lawyer may speak for you in front of the magistrate judge.

The one exception: business entities (corporations, LLCs, partnerships) can send an officer, partner, or full-time employee to appear on their behalf — as long as that person is not an attorney. They need to bring written authorization, like a corporate resolution or a signed letter from management.

Counterclaims Are Prohibited

Under I.R.S.C.A. Rule 5, a defendant cannot file a counterclaim inside the plaintiff's small claims case. If the defendant believes the plaintiff owes them money from the same transaction, they must file a completely separate small claims action, pay the $69 filing fee, and serve the plaintiff independently.

The court can consolidate both cases for a single hearing under I.R.S.C.A. Rule 6, but they remain procedurally separate filings. If the defendant's cross-claim exceeds $15,000 or involves relief beyond small claims jurisdiction, it goes to Magistrate Division or District Court, and the original small claims case may be transferred up under I.R.S.C.A. Rule 7.

The 21-Day Answer Window

After a defendant receives the summons and complaint, they have exactly 21 calendar days to file a written answer (Form CAO SC 3-1) with the court clerk. This is different from states where defendants simply show up on the trial date. Missing the 21-day deadline opens the door to a default judgment against the defendant.

Relaxed Evidence Rules With Real Requirements

Formal Idaho Rules of Evidence are relaxed in small claims hearings, but "relaxed" does not mean "anything goes." The burden of proof stays on the plaintiff — you must prove your case by a preponderance of the evidence (more likely than not). Magistrate judges expect printed documents: contracts, invoices, bank statements, dated photographs, and text message screenshots. Evidence stored only on a phone screen will not be admitted. Bring the original plus three copies — one for the judge, one for the opposing party, one for your own reference, and the original for marking as an exhibit.

Venue Rules

You must file in the Magistrate Division of the county where the defendant lives or where the dispute arose (where the contract was performed, where the property is located, or where the damage happened). Filing in the wrong county can result in a venue transfer or dismissal.

What Happens at the Hearing

Small claims trials are informal bench trials before a magistrate judge. The sequence: the plaintiff presents first (opening statement, evidence, witnesses), the defendant cross-examines, then the defendant presents their side. The judge may ask direct questions to both parties. The judge may rule from the bench or take the matter under advisement and mail a written judgment to the parties.

An aggrieved party who did not default or fail to appear may appeal within 30 calendar days of the judgment's entry by paying the $81 fee. The appeal is a trial de novo — a completely fresh trial in front of a lawyer magistrate or district judge, where attorneys are permitted.

Plan Your Filing Around These Rules

Understanding Idaho's small claims rules before you file prevents the procedural mistakes that delay or sink otherwise valid claims.
