Diminished value claims in Hawaii

Can you claim diminished value in Hawaii?

Short answer: Hawaii courts have not clearly decided whether you can recover it from the at-fault driver's insurer.

No Hawaii appellate decision allowing or rejecting diminished-value recovery for a repaired car was found. A law-firm 50-state survey (Matthiesen, Wickert & Lehrer, updated 3/16/2022) reports no Hawaii decisions on third-party vehicle DV; Hawaii courts have used diminution in value only in condemnation and real-property contexts. First-party DV depends on the policy wording. A third-party claim under general tort damages principles may be possible but is unconfirmed.

How to file a diminished value claim in Hawaii

1. Finish the repair and get the final invoice showing every part and labor operation.
2. Document the pre-accident value of your exact trim and mileage.
3. Collect proof of the loss: a vehicle history report showing the accident, written trade-in offers, or an independent appraisal.
4. Send a written demand to the at-fault driver's insurer with a specific amount and your evidence.
5. If they refuse or lowball, you can sue the at-fault driver in small claims court before the deadline.

How to document the value before and after

• Before: save listings for cars of the same year, trim and mileage from just before the accident, and any records of options, upgrades and maintenance.
• After: get at least two written trade-in or purchase offers from dealers who see the repaired car and its history report.
• Keep the repair invoice, photos of the damage and the history report entry; they show what a buyer will see.

Will the insurer use the 17c formula in Hawaii?

Many adjusters calculate diminished value by capping it at 10% of the car's value and then applying damage and mileage multipliers. The result is often a few hundred dollars. It is not based on what buyers actually pay, and you do not have to accept it. How the 17c formula works.

Deadline to file a diminished value claim in Hawaii

Short answer: You generally have 2 years to sue the at-fault driver for damage to your car (HRS s. 657-7). That is the shorter of two possible deadlines in state law. Send your written demand well before then.

Property damage claims in Hawaii generally must be filed in court within 2 years of the accident.
