Idaho Diminished Value Claims — The Complete Guide.

Idaho's Boel v. Stewart Title Recognition Applied to Vehicles.

Idaho courts have addressed diminution-in-value in the real property context. Boel v. Stewart Title Guaranty Co., 43 P.3d 768 (Idaho 2002), addressed the requirement to show diminution in value of real property in a suit against a title company. While the case addresses real property and title insurance rather than vehicle DV, the decision recognizes diminution-in-value as a valid measure of damages in Idaho — supporting the doctrinal foundation for vehicle DV recovery in third-party tort claims.

Idaho's substantive vehicle DV framework rests on standard property damage tort principles: difference between fair market value before the loss and fair market value after the loss, plus reasonable cost of repairs where applicable. Idaho's 3-year SOL under Idaho Code § 5-218 governs property damage tort actions. Idaho Small Claims Department of Magistrate Court handles claims up to $5,000 and prohibits attorney representation in small claims. Modified comparative negligence under Idaho Code § 6-801 (50% bar).

Idaho Authority: Real Property Recognition + Standard Tort Framework

Idaho's DV recognition in real property cases supports the doctrinal foundation for vehicle DV recovery in tort.

Idaho Insurers Use 17c — The Tort Framework Doesn't.

Idaho's third-party tort framework is market-based: pre-loss market value minus post-loss market value, plus reasonable cost of repairs. The 17c formula's mechanical multipliers don't match this. Idaho insurers default to 17c. A demand letter citing Idaho's property damage tort framework and Boel v. Stewart Title's recognition of diminution-in-value puts the claim on solid Idaho Supreme Court footing.

Run 17c first to anticipate the insurer's initial offer, then quantify the gap to Idaho's tort framework:

Filing a Diminished Value Claim in Idaho.

Idaho's framework is evolving but doctrinally recognized. Boel v. Stewart Title recognizes diminution-in-value. The 3-year SOL gives reasonable time. Modified comparative with 50% bar.

1. Document liability. Idaho applies modified comparative negligence under Idaho Code § 6-801 with a 50% bar. Police report, witnesses, dashcam, traffic cameras.
2. Complete repairs. Idaho DV is calculated post-repair under the property damage tort framework.
3. Establish pre-accident market value. Idaho-market comparables — Boise, Meridian, Nampa, Idaho Falls, Pocatello, Coeur d'Alene, Caldwell. Idaho's growing market produces solid comparable data.
4. Document post-repair value. Two written dealer trade-in offers post-repair plus comparable sales of similar Idaho vehicles with accident-history Carfax. Discount typically runs 12-22%.
5. Prepare a USPAP-compliant appraisal. The appraisal cites Boel v. Stewart Title Guaranty Co. for Idaho's recognition of diminution-in-value, references the standard property damage tort framework, and uses Idaho-market comparables.
6. Send a demand letter. Quote Boel's recognition of diminution-in-value. Reference Idaho Code § 5-218's 3-year SOL window. Send certified mail.
7. Allow 30 days for response. Idaho insurers may resist longer than in stronger DV states given the absence of reported Idaho vehicle-DV authority. Be patient but firm.
8. File an Idaho Department of Insurance complaint. doi.idaho.gov handles complaints. Idaho DOI complaints add regulatory pressure.
9. Small Claims Department for $5,000 or less; Magistrate Court above. Idaho Small Claims Department of Magistrate Court handles claims up to $5,000. Note: Idaho prohibits attorney representation in small claims. Above $5,000, full Magistrate Court procedure applies.
10. Consider full Magistrate Court for borderline claims. Given Idaho's small claims attorney prohibition and $5,000 cap, claims above $5,000 or those benefiting from attorney representation should pursue full Magistrate Court procedure.
