The Personal Auto Policy & Diminished Value Claims


When a car is damaged in an accident, then repaired, the resale value may be less than that for a comparable car that has not been damaged. In other words, the damage results in a reduction, or “diminution,” in the resale value of the auto. An insured’s claim for this reduction in value may be made against a third party that negligently caused the damage to the insured’s auto, or it may arise from a first-party claim against the insured’s own physical damage coverage.

With regard to first-party claims, while it is perhaps arguable, the ISO Personal Auto Policy contract language appears to cover only the actual cash value of the damage or the actual cost to repair the damage. It does not appear to contractually cover any reduction in market value even if the insured was able to prove such.

Third-party claims for “diminution of value,” on the other hand, have generally been found by the courts to be covered by auto insurance. The Liability Coverage section of the Personal Auto Policy pays for any property damage for which the insured is legally responsible. Such legal liability may be established by case law or it may be statutory.

According to our research, most courts have recognized diminution of value as being legally compensable to the extent that the plaintiff can demonstrate such reduction in market value. Also, most case law seems to have held that, in first-party claims, the contract governs.

For example, several Texas court cases have found that legal liability for third-party damages includes diminution of value. In Ludt v. McCollum, 762 S.W.2d 575 (Tex. 1988); Terminix International, Inc. v. Lucci, 670 S.W.2d 657 (Tex. App. 1984):

“An aggrieved consumer may be able to plead, prove and obtain favorable jury findings establishing both costs to repair and permanent reduction in market value notwithstanding such repairs, as cumulative rather than mutually exclusive measures of damages.”

“An award of diminished value is recoverable in addition to the costs of repair, assuming that the permanent reduction in value refers to that reduction occurring even after repairs are made.”

In Northwestern Nat. Ins. Co. v. Cope, 48 S.W.2d 717 (Tex. Civ. App. 1969), the court stated:

“Three months after purchase of new car, insured Cope was involved in accident. Cope contended that after repairs to her auto, its value would be $1,440 less than prior to the accident.”

“Thus, she argued that the measure of her recovery should be the difference in the reasonable cash market value of the auto immediately before and after accident, and should not be tested by reasonable cost of repair.”

“Held, such measure of damages is proper.”

In summary, there appears to be nothing in the ISO standard Personal Auto Policy (PAP) that requires the carrier to compensate the insured for diminution of value in physical damage claims…in fact, the contract seems to support the position that such consequential loss is not covered.

In contrast, there is ample case law to demonstrate that such diminution of value is legally recoverable from a third party and, thus, covered under the liability section of the auto policy.

Note: Some insurance companies may be using a relatively new endorsement called the Coverage for Damage to Your Auto Exclusion Endorsement, which is not yet approved in all states (in fact, some states have specifically disapproved this form). The endorsement clarifies that diminution of value claims are NOT covered by the PAP. If your policy has such an endorsement, then you can be assured that diminution claims are not covered by your policy.

    Thanks for the informative article! Very informative, especially in discerning between 1st party and 3rd party claims. In my understanding, the stipulations for diminished value claims varies on a state-by-state basis depending on the laws of that state. I know in Georgia, any damage to your vehicle at all is eligible for a diminished value claim. Even if lets say…a tree fell on your car. I would like to get a discussion going concerning this subject. I know there are differing opinions on the matter.

    Thanks again for this post!
