Hawaii courts have never ruled on lost value after a car repair, so a diminished value claim in Hawaii starts from general damage law. The claim is still open. It just leans hard on proof and timing.
An Open Question in the Courts
The MWL chart of all 50 states found no Hawaii decision on the lost value of a damaged car in a third-party claim. Hawaii judges have used the idea, but only to set value in condemnation cases. No ruling covers a claim on your own car policy either.
Without a case to cite, the adjuster will want hard numbers. A written appraisal shows the gap between the value before the crash and the value after the repair. Send it to the at-fault driver's insurer with a short demand letter.
Small Claims Court Takes Car Accident Cases
The Hawaii State Judiciary lists car accident damage claims among the cases its small claims court hears. The limit there is $5,000. A modest lost value claim can fit under that cap on its own. A bigger loss has to go to a higher court.
Two Years and the Fault Split
Hawaii sets a two-year limit for damage to persons or property in Haw. Rev. Stat. § 657-7. The time runs from when the cause of action accrued. Mark the date early, and do not let slow talks with the insurer drift past it.
Shared blame is handled by Haw. Rev. Stat. § 663-31. Your share of the fault only blocks the claim once it is larger than the other side's. The Justia survey calls this a 51 percent bar. Below that line, the award shrinks by your share of the fault.
Higher Policy Limits from 2026
New minimums took effect on January 1, 2026, per the Insurance Division FAQ. Every policy must now carry $20,000 in property damage liability per accident. Unless the other driver bought more, that figure is the most the policy pays for your repair and lost value combined.
If a claim stalls, the Hawaii Insurance Division asks drivers to speak with one of its investigators before filing a complaint. For a state where the rule is settled law, compare Georgia.
