Proof decides a diminished value claim in Wisconsin. The courts let you recover lost value from the at-fault driver, but only after you show that the repairs fell short.
Hellenbrand and the Burden of Proof
The leading case is Hellenbrand v. Hilliard, from 2004. The owner's minivan was worth about $23,000 just before the crash and $19,000 after it was repaired. A lower court had ruled for the insurer. The Court of Appeals reversed and sent the case back.
The Matthiesen, Wickert & Lehrer survey states the rule. An owner gets repair costs and loss of value after repair if the owner proves the repairs did not restore the car. In that case the gap was $4,000. A diminished value appraisal is how most owners show such a gap.
Wildin and Your Own Policy
Your own insurer is a dead end here. In Wildin v. American Family, from 2001, the policy let the company pay only for repairs. That held even if the repairs could not bring the car back to its value before the collision.
Three Years and the Fault Comparison
For property damage from an accident involving a motor vehicle, Wis. Stat. § 893.52(2) gives you 3 years after the claim accrues. Miss that date and the claim is barred.
Fault is compared under Wis. Stat. § 895.045. You may still collect as long as your negligence does not exceed the other driver's. Your award then drops in line with your share.
Small Claims Has Two Limits
Wisconsin small claims court takes claims of $10,000 or less. Tort claims, such as a negligence claim against another driver, are limited to $5,000, per the Wisconsin court system. Plan around the lower figure.
The required property damage liability is only $10,000. If the at-fault driver carries just that much, it must cover repairs and lost value together. For delays or vague offers, contact the Wisconsin Office of the Commissioner of Insurance.
