Tennessee Diminished Value Claims — The Complete Guide.

Tennessee's Either-Or Recovery Limitation.

Tennessee is unique among the states we cover in limiting DV recovery to an either-or election. The Tennessee Court of Appeals in Grimes v. Hancock (M2011-01940-COA-R3-CV, June 2012) held: "the measure of damages is either repair costs or the difference in market value immediately before the accident and that immediately after the accident. It is not both. Unlike the Restatement provision, decrease in value measured after the repair is not a recognized element of allowable damages in Tennessee."

This makes Tennessee less favorable than the both-elements states (Ohio, Illinois, New Jersey, Pennsylvania, Maryland). Tennessee claimants must choose: either accept repair costs (typically what the insurer pays) OR pursue the gross diminution (pre- minus post-accident market value). The earlier GEICO v. Bloodworth class action framework still applies as the procedural baseline, and Tennessee UMPD coverage can include DV as optional coverage. T.C.A. § 28-3-105 provides a 3-year SOL.

Tennessee's Two-Decision Framework

Tennessee DV law rests on a 2007 class action and a 2012 limiting decision. The framework is restrictive compared to most states.

Tennessee's Calculation: Pick the Higher One.

Under Grimes, Tennessee claimants choose between (1) reasonable repair costs and (2) the difference in market value before and after the accident. The calculator shows the market difference. Compare against the actual repair cost to determine which is higher — that's the recoverable amount under Grimes. In most cases, the gross-diminution measure produces a larger number than repair costs alone, so the calculator's output is typically the right basis for the demand.

Calculate the gross diminution. Compare against repair costs. Demand the higher of the two:

Filing a Diminished Value Claim in Tennessee.

Tennessee's restrictive framework requires careful claim structuring. The either-or election under Grimes is the central procedural choice.

1. Document liability. Tennessee applies modified comparative negligence — recovery barred at 50%+ fault, reduced proportionally below that. Police report, witnesses, dashcam.
2. Complete repairs. Tennessee DV is calculated post-repair. Document the repair cost separately because under Grimes, you'll choose between repair cost and market diminution.
3. Establish pre-accident market value. Tennessee-market comparables — Nashville, Memphis, Knoxville, Chattanooga, Clarksville. TN's growing population (especially Nashville metro) produces dense comparable data.
4. Document post-accident market value. Critical for Tennessee under Grimes: you need pre-accident AND post-accident market values to establish the gross diminution measure. The post-repair value is also relevant for showing the repair didn't restore the vehicle.
5. Compare repair cost vs. gross diminution. Under Grimes, you must elect one. Calculate both. Demand the higher amount.
6. Prepare a USPAP-compliant appraisal. The appraisal cites GEICO v. Bloodworth for the three-element proof framework, addresses Grimes's either-or rule, and produces both the gross diminution number and repair cost figure.
7. Send a demand letter. Cite Bloodworth for the proof framework. Address Grimes by demanding the higher of (1) repair cost or (2) gross diminution. Send certified mail.
8. Allow 30 days for response. Tennessee insurers typically respond within 14-30 days. Be prepared for the insurer to argue for the lower of the two measures.
9. File a Tennessee Department of Commerce and Insurance complaint. tn.gov/commerce handles complaints. TDCI complaints add regulatory pressure.
10. Small claims (General Sessions Court) for $25,000 or less. Tennessee General Sessions Court handles civil claims up to $25,000 — one of the highest small claims caps in the country. Attorneys are permitted. Most TN DV claims fit within this jurisdiction.
