How to File Small Claims in Idaho — Step-by-Step Filing Process

Step 1: Confirm Your Claim Qualifies

Before anything else, check three things:

• Dollar amount: small claims jurisdiction covers money claims up to $15,000 (the limit since July 1, 2026 under SB 1330). If your claim is higher, you can use small claims only if you waive recovery above the cap.
• Type of claim: you're seeking money or the return of personal property — not an injunction, punitive damages, or emotional distress
• Statute of limitations: written contracts get 5 years (Idaho Code § 5-216), oral contracts 4 years (§ 5-217), property damage 3 years (§ 5-218), personal injury 2 years (§ 5-219)

If you need a remedy small claims cannot award, file in regular Magistrate or District Court. If your claim exceeds the small-claims limit, you can file there for the full amount or use small claims only if you waive the excess.

Step 2: Identify the Defendant Correctly

Get the defendant's exact legal name. For a person, use their full legal name. For a business, search the Idaho Secretary of State's business registry (SOSBiz at sosbiz.idaho.gov/search/business) to find the registered entity name and registered agent address.

Common mistake: naming a trade name or storefront instead of the actual LLC or corporation. A judgment against "Joe's Plumbing" is unenforceable if the legal entity is "Joseph Smith Plumbing Services, LLC." Get the registered name right.

Step 3: Send a Demand Letter

A written demand letter isn't strictly required for most claims, but it's smart for two reasons: it often triggers a settlement without court, and it shows the judge you tried to resolve the dispute first.

For security deposit claims, the demand letter is mandatory. Idaho Code § 6-320 requires tenants to give landlords a written 3-day notice and demand before filing. Skip this step and your case gets dismissed for lack of standing.

Step 4: Determine the Right County

Under Idaho Code § 1-2301, you file in the county where:

• The defendant lives, or
• The dispute arose (where the contract was performed, where the rental property is, where the damage happened)

Filing in the wrong county means the defendant can move to dismiss or transfer your case.

Step 5: Complete and File Your Forms

You need two forms to start:

• CAO SC 1-2 (Claim of Plaintiff) — your complaint stating the facts and the amount claimed
• CAO SC 1-1 (Summons) — issued by the clerk after you file

Bring these to the magistrate clerk's office with the $69 filing fee. You can also file electronically through iCourt Guide & File. Business entities must e-file; Guide & File may be used for Court Assistance Office forms when available, while other documents must be filed through File & Serve.

The clerk stamps your documents, assigns a case number, issues the summons, and returns service copies to you.

Step 6: Serve the Defendant

You cannot serve the defendant yourself. Idaho law requires one of three methods:

1. County sheriff ($30–$45) — hand-delivers the packet
2. Private process server — any adult over 18 who isn't a party to the case
3. Certified mail through the clerk ($10.10 through Oct. 22, 2026; $11.35 starting Oct. 23) — service is complete when the return receipt is signed by the defendant or an authorized agent

The service packet must include four documents: the summons, your complaint, a blank answer form (CAO SC 3-1), and defendant instructions.

After service, file the Affidavit of Service (Form CAO SC 2-1) with the clerk. Under I.R.S.C.A. Rule 10, if the summons has not been issued and served within 30 days, the court may dismiss the action without prejudice after notice. The court may reopen it without another filing fee if you request this within six months of the original filing and it appears the defendant can be served.

Step 7: Wait for the Response

The defendant has 21 calendar days from service to file a written answer. If they don't answer, you can apply for a default judgment — but it's not automatic. You still need to submit evidence of your claim and proof of proper service.

Step 8: Prepare for the Hearing

Bring four complete printed copies of every document supporting your claim: contracts, receipts, bank statements, photos, text messages, emails. The judge won't look at your phone screen.

Organize your materials so you can present your case clearly in a few minutes. The magistrate judge will ask questions, and the defendant gets to cross-examine.

Step 9: Attend the Hearing

The hearing is informal — no jury, no attorneys (they're prohibited under I.R.S.C.A. Rule 8(b)). The judge hears both sides, reviews the evidence, and either rules from the bench or mails a written decision.

If you win, the judgment includes your damages plus any court costs you asked for. The losing side has 30 days to file an appeal.
