Idaho Small Claims Counterclaim: How to Sue Back

You've been sued in Idaho small claims court, but the plaintiff actually owes you money too. Maybe the contractor who's suing you for unpaid work left your kitchen half-demolished. Maybe the landlord claiming damages never returned your security deposit. You want to counterclaim — and Idaho makes that surprisingly complicated.

Why You Can't Counterclaim on the Answer Form

Under I.R.S.C.A. Rule 5, counterclaims are strictly prohibited within a small claims proceeding. You cannot write a counterclaim on your Answer form (CAO SC 3-1), attach it as a separate page, or ask the judge to hear your affirmative claim during the small claims trial. It simply won't be considered.

This catches a lot of defendants off guard, especially those who've been through small claims court in other states where counterclaims are standard.

Route 1: File a Separate Small Claims Case

The more straightforward option is to file your own, independent small claims action against the person suing you. You become the plaintiff in a second case.

Here's how it works:

• File a new Small Claim using Form CAO SC 1-1 at the Magistrate Clerk's office or through Guide & File
• Pay the $69 filing fee
• Serve the other party (who is the plaintiff in the original case)
• Once both cases are filed, the Magistrate Judge can consolidate them under I.R.S.C.A. Rule 6 — meaning both cases get heard together at a single hearing

For actions filed on or after July 1, 2026, the small claims monetary limit is $15,000; actions filed before that date remain subject to the $5,000 limit. This route works when your claim is within the applicable small claims limit and involves money or specific personal property. The consolidation means you're not attending two separate hearings on the same dispute.

Route 2: Transfer to District Court

If your cross-claim arises from the same transaction or occurrence as the plaintiff's claim and exceeds the applicable small claims limit, or if it requires a remedy small claims can't grant — like an injunction or specific performance — you'd need to file a regular civil action in the Magistrate Division or District Court. For actions filed on or after July 1, 2026, the limit is $15,000; earlier cases remain subject to the $5,000 limit. A claim arising from the same transaction may be a compulsory counterclaim under Idaho Rule of Civil Procedure 13(a).

Under I.R.S.C.A. Rule 7, the judge in your regular civil case can order the original small claims action transferred and consolidated. Once that happens, summary small claims procedures end. Both cases proceed under standard civil rules with formal discovery, regular pleading requirements, and attorney representation on both sides.

This route is more expensive and complex, but it's the only option when your claim doesn't fit within small claims jurisdiction.

Don't Forget to File Your Answer First

Regardless of which counterclaim route you choose, you still need to file your Answer in the original case within 21 days of being served. The counterclaim process is separate from — and doesn't replace — your obligation to respond to the case against you. If you miss the 21-day deadline while figuring out your counterclaim, you'll face a default judgment on the plaintiff's claim.

File the Answer first, then pursue your counterclaim through one of the two routes above.
