Colorado Diminished Value Claims — The Complete Guide.

Colorado's Century-Old Framework.

Colorado's DV law rests on two Colorado Supreme Court decisions: Larson v. Long (1923), which established that depreciation evidence is admissible as an element of damage, and Trujillo v. Wilson (1948), which clarified the measure of damages as "the difference between [the property's] value immediately before its damage and immediately thereafter, together with any expense of reasonable efforts to preserve or restore it." These decisions remain controlling.

Notably, Colorado's Pattern Civil Jury Instructions explicitly direct juries on how to calculate DV — instructing them to award compensation equal to the difference between the property's market value immediately before and after the accident. This jury-instruction framework gives Colorado DV claimants a clear standard that insurers must answer to. Colorado applies modified comparative negligence under C.R.S. § 13-21-111, which means recovery is barred only if you're 50% or more at fault.

Colorado Authority: 100 Years of Case Law

Colorado's DV framework is built on two Colorado Supreme Court decisions, codified in the Pattern Jury Instructions, and constrained by the modified comparative negligence statute.

17c Conflicts With Colorado's Pattern Jury Instructions.

Colorado's Pattern Jury Instructions direct juries to compare pre-accident and post-repair market value — a direct, market-based standard. The 17c formula's mechanical multipliers don't match this standard. State Farm and other major Colorado insurers default to 17c anyway. A demand letter that contrasts the Pattern Jury Instruction standard against 17c demonstrates that you understand how a Colorado jury would actually decide your claim.

Run 17c yourself to anticipate the insurer's initial offer, then compare against the Pattern Jury Instruction's market-based measure in your appraisal:

Filing a Diminished Value Claim in Colorado.

Colorado's framework is well-settled. Three Colorado Supreme Court / appellate authorities (Larson, Trujillo, the Pattern Jury Instructions) align on the measure of damages. The 3-year SOL provides reasonable time. Modified comparative negligence allows partial recovery in shared-fault situations.

1. Document liability. Colorado's modified comparative negligence is more forgiving than VA/NC's pure contributory rule, but fault percentage still affects recovery. Police report, witness statements, and any available camera footage establish your fault percentage.
2. Complete repairs. Colorado DV is calculated post-repair. Document repairs: estimates, invoices, parts list, scan reports, paint thickness, frame measurements.
3. Establish pre-accident market value. Colorado-market comparables — Denver, Aurora, Colorado Springs, Fort Collins, Lakewood, Boulder. Mountain region buyers (Vail, Aspen, Steamboat) often pay premium for AWD/4x4 vehicles.
4. Document the post-repair value. Two written dealer trade-in offers post-repair plus comparable sales of similar Colorado vehicles with accident-history Carfax. Discount typically runs 12-22%.
5. Prepare a USPAP-compliant appraisal. The appraisal cites Larson v. Long and Trujillo v. Wilson, uses Colorado-market comparables, and aligns with the Pattern Civil Jury Instructions' standard.
6. Send a demand letter. Cite both Larson and Trujillo. Reference the Pattern Jury Instructions to signal your awareness of how a Colorado jury would decide. Note the 3-year SOL window. Send certified mail.
7. Allow 30 days for response. Colorado insurers familiar with the controlling case law typically respond within 14-30 days.
8. File a Colorado Division of Insurance complaint. doi.colorado.gov handles consumer complaints. DOI complaints add regulatory pressure.
9. Small claims for $7,500 or less; county court above. Colorado small claims is capped at $7,500 (C.R.S. § 13-6-403). No attorneys allowed in small claims. County court handles up to $25,000.
10. Consider district court for larger claims. Above $25,000, Colorado district court handles the case with full procedure. Most DV claims fit within county court's $25,000 jurisdiction.
