Understanding Diminished Value Claims
Diminished value represents the gap between your vehicle’s market value before an accident and its value after repairs. Even high-quality repairs cannot fully restore market value. In New Hampshire, you may recover this loss from the at-fault driver’s liability insurer.
New Hampshire law treats failure to pay valid claims as an unfair trade practice. See N.H. Rev. Stat. Ann. § 412:13.
Step-by-Step Submission Process
- Review Your Policy and Identify the At-Fault Insurer
You file a diminished value claim with the at-fault driver’s liability insurer, not your own company. - Gather Documentation
Collect your insurance policy declarations, accident report, repair invoices, photos of damage, and pre- and post-repair market valuations. - Obtain an Independent Appraisal
Hire a certified appraiser to calculate diminished value. This professional report strengthens your demand. - Draft a Demand Letter
Address the insurer, summarize the accident, attach all documentation, state your diminished value amount, and cite N.H. Rev. Stat. Ann. § 412:13. - Submit Your Claim
Send your demand letter and attachments by certified mail or via the insurer’s online portal. Keep proof of delivery. - Follow Up in Writing
If the insurer requests more information, respond promptly. Document each communication by email or letter. - Escalate if Needed
If the insurer denies or undervalues your claim, file a complaint with the New Hampshire Insurance Department: nh.gov/insurance/consumers/complaints.
