Indiana Diminished Value Claims — The Complete Guide.

Indiana's Three-Method Proof Framework.

Indiana's controlling case is Wiese-GMC, Inc. v. Wells, 626 N.E.2d 595 (Ind. Ct. App. 1993). The Court of Appeals laid out a clear framework: "the fundamental measure of damages in a situation where an item of personal property is damaged, but not destroyed, is the reduction in fair market value caused by the negligence of the tortfeasor." This reduction may be proved in three ways: (1) by evidence of fair market value before and fair market value after; (2) by evidence of the cost of repair where repair will restore property to its fair market value before; or (3) by cost of repair PLUS reduction in fair market value if repair doesn't fully restore.

Indiana's first-party path is foreclosed. Allgood v. Meridian Security Insurance Co., 836 N.E.2d 243 (Ind. 2005), held that an insurance policy providing coverage for loss limited to the lesser of actual cash value or amount necessary to repair or replace does not obligate the insurer to compensate for diminution after adequate repairs have been made. The Indiana Supreme Court denied transfer 5-0, making this controlling first-party authority. The framework is therefore third-party only via tort, with UMPD as an optional path for hit-and-run scenarios.

Indiana Authority: Two Decisions, Different Directions

Indiana DV law has clear third-party authority and equally clear first-party foreclosure. The combination produces a tort-only recovery framework.

Indiana Insurers Use 17c — Wiese-GMC Doesn't.

Indiana's controlling standard from Wiese-GMC is market-based and offers three proof methods, including cost of repair PLUS residual diminution. The 17c formula's mechanical multipliers don't match this framework. Major Indiana insurers default to 17c when calculating initial offers. A demand letter quoting Wiese-GMC's three-method framework and citing Indiana's tort-only DV recovery posture (post-Allgood) puts the claim on solid Indiana appellate footing.

Run 17c first to anticipate the insurer's initial offer, then quantify the gap to Wiese-GMC's market-based standard:

Filing a Diminished Value Claim in Indiana.

Indiana's framework is well-developed for third-party. The 2-year SOL means timing matters. UMPD provides backup for uninsured-driver scenarios (but not hit-and-run).

1. Document liability. Indiana applies modified comparative negligence — recovery barred at 51% or more fault. Police report, witnesses, dashcam, traffic camera footage.
2. Determine recovery path. Three options: third-party against at-fault driver's liability insurer (most common), UMPD against your own policy if at-fault driver is uninsured (NOT hit-and-run; Indiana UMPD doesn't cover that), or UIMPD if at-fault liability coverage is inadequate.
3. Complete repairs. Indiana DV is calculated post-repair under Wiese-GMC. Document repairs comprehensively.
4. Establish pre-accident market value. Indiana-market comparables — Indianapolis, Fort Wayne, Evansville, South Bend, Carmel, Bloomington. Indianapolis metro produces dense comparable data.
5. Document post-repair value. Two written dealer trade-in offers post-repair plus comparable sales of similar Indiana vehicles with accident-history Carfax. Discount typically runs 12-22%.
6. Prepare a USPAP-compliant appraisal. The appraisal cites Wiese-GMC v. Wells, references the three-method framework, and uses Indiana-market comparables. The appraisal should support whichever of the three methods you elect.
7. Send a demand letter. Quote Wiese-GMC's three-method language. Elect Method 3 (repair cost PLUS residual diminution) when you can support both elements. Send certified mail.
8. Allow 30 days for response. Indiana insurers familiar with Wiese-GMC typically respond within 14-30 days.
9. File an Indiana Department of Insurance complaint. in.gov/idoi handles complaints. IDOI complaints add regulatory pressure.
10. Small claims for $10,000 or less; circuit court above. Indiana small claims handles claims up to $10,000. Attorneys are permitted. Filing fees are modest. Above $10,000, circuit court handles the case with full procedure.
