Idaho Demand Letter

Introduction

Key Things to Know

1. 1

   Idaho Code Section 12-120(1) conditions attorney's-fee shifting on a written demand for payment sent at least 10 days before you file suit, for a civil claim of $35,000 or less; you lose that right if the other side tenders at least 95 percent of the eventual award before you sue. A personal-injury claim of $35,000 or less instead requires a 60-day written demand under Section 12-120(4).

2. 2

   If this claim instead arises from a commercial transaction, such as an open account, a note, or a contract for the sale of goods or services, Idaho Code Section 12-120(3) shifts fees to the prevailing party with no dollar cap and does not require a pre-suit demand.

3. 3

   No Idaho statute requires pre-suit notice before a private damages claim under the Idaho Consumer Protection Act, Idaho Code Section 48-608, but a prevailing consumer recovers actual damages or $1,000, whichever is greater, plus mandatory attorney's fees, and a consumer who is 62 or older or disabled can recover an enhanced penalty of $15,000 or treble actual damages on specific court findings.

4. 4

   A dishonored check pays differently depending on where you sue: Idaho Code Section 1-2301A lets you recover the check amount plus the greater of $100 or three times the check amount, capped at $500 over the check's value, but only in the Small Claims Department and only after a 10-day written demand.

5. 5

   If you sue on a dishonored check in district court instead of small claims, Idaho Code Section 28-22-105 gives you 12 percent annual interest from the date of dishonor and a collection cost capped at $20, but only after a separate 15-day notice of dishonor in the statutory form Idaho Code Section 28-22-106 prescribes.

6. 6

   Idaho's Small Claims Department of the Magistrate's Division hears claims up to $15,000 for a natural person or a business under a 2026 amendment to Idaho Code Section 1-2301, but no attorney may appear for either side at the trial itself under Section 1-2307, though you may consult one beforehand.

7. 7

   Idaho's Collection Agency Act, Idaho Code Sections 26-2221 to 26-2233, regulates third-party collection agencies and buyers of already-delinquent debt, not an original creditor collecting its own account; regardless, never threaten arrest, jail, or criminal prosecution to collect a civil debt.

Idaho Requirements for Demand Letter

• Idaho Code 12-120(1): 10-Day Fee-Shifting Demand

  For a civil claim of $35,000 or less, Idaho Code Section 12-120(1) lets a court award attorney's fees to the prevailing party only if the plaintiff sent a written demand for payment at least 10 days before filing suit, and only if the defendant did not tender at least 95 percent of the eventual award before suit. A personal-injury claim of $35,000 or less instead requires a 60-day written demand under Section 12-120(4).

• Commercial Transactions Skip the Demand Requirement

  Idaho Code Section 12-120(3) shifts attorney's fees to the prevailing party in a commercial transaction, such as an open account, a note, or a contract for the sale of goods or services, with no dollar cap and no pre-suit written demand required.

• ICPA Has No Pre-Suit Notice, But Fees Are Mandatory

  No Idaho statute requires pre-suit notice before a private damages claim under the Idaho Consumer Protection Act, Idaho Code Section 48-608. A prevailing consumer recovers actual damages or $1,000, whichever is greater, plus mandatory attorney's fees under Section 48-608(1) and (5), and an elderly (62 or older) or disabled consumer can recover an enhanced penalty of $15,000 or treble actual damages on specific court findings under Section 48-608(2).

• Bad-Check Recovery Differs by Forum

  Idaho Code Section 1-2301A lets a Small Claims Department plaintiff recover the check amount plus the greater of $100 or three times the check amount, capped at $500 over the check's value. A district-court plaintiff instead gets no multiplier, but under Section 28-22-105 recovers 12 percent annual interest from the date of dishonor, a collection cost capped at $20, and court-awarded attorney's fees.

• Small-Claims Bad-Check Demand Delivery Method

  Idaho Code Section 1-2301A requires the written demand to be sent at least 10 days before filing, by certified mail to the check writer's last known address, or by regular mail supported by an affidavit of service to the address on the check, deemed served 3 days after the affidavit is executed.

• District-Court Notice of Dishonor Uses a Statutory Form

  Idaho Code Section 28-22-106 prescribes the required content of the notice of dishonor that starts the 15-day cure period before interest, collection costs, and attorney's fees attach under Section 28-22-105; this letter does not replicate that statutory form and a separate notice following it is needed.

• Small Claims Limit and No Attorneys at Trial

  Idaho's Small Claims Department hears claims up to $15,000 for a natural person or a business under a 2026 amendment to Idaho Code Section 1-2301. No attorney may appear for either side at the trial itself under Section 1-2307, though a party may consult one beforehand.

• Statute of Limitations by Claim Type

  Idaho gives 5 years to sue on a written contract under Idaho Code Section 5-216, 4 years on an oral contract or an unwritten open account under Section 5-217, and 3 years for injury to or taking of personal property under Section 5-218.

• Interest Runs From the Due Date, Not the Demand

  Idaho Code Section 28-22-104(1) allows interest of 12 percent per year on money due by contract when the parties set no rate, running from the date the amount became due rather than from the date of a demand letter. A post-judgment rate of 5 percent plus a base rate the state treasurer sets annually applies once a judgment is entered, under Section 28-22-104(2).
