Short answer
If your vehicle lost market value after a crash, you can request a diminished value quote in New Jersey by collecting evidence of pre- and post-accident condition, obtaining an independent appraisal or written estimate from a trained appraiser, and presenting that documentation to the at-fault driver’s insurer (or to your own insurer if appropriate). Keep careful records, ask for a written decision, and escalate if the insurer refuses to pay. This article explains the steps, the evidence you should gather, and practical next steps under New Jersey consumer-insurance practices.
Detailed Answer
What diminished value means
Diminished value is the difference between a vehicle’s fair market value immediately before an accident and its fair market value after repairs. Even flawlessly repaired vehicles often sell for less than similar, undamaged vehicles because buyers prefer cars with no prior damage history.
Who can seek diminished value in New Jersey
Anyone whose vehicle was damaged by another driver’s negligence can typically seek diminished value from the at-fault driver’s liability insurer as part of the property-damage claim. You may also try a first‑party claim with your own insurer depending on your policy and circumstances, but pursuing the at-fault carrier is the common route.
How insurers usually handle diminished value
Insurers evaluate diminished value claims differently. Some accept independent appraisals; others rely on internal assessments. In any event, you should present documentation and a clear valuation method to make your claim persuasive.
Step-by-step process to get a reliable diminished value quote
- Document the accident and vehicle condition. Take clear photos of all damage, the repaired areas, the vehicle’s exterior, interior, odometer, VIN plate, and any previous damage stickers or notes. Save the police report and all communications with insurers.
- Gather repair and maintenance records. Keep the repair estimate, final invoice, parts receipts, and any written warranty for repairs. These show what was fixed and how.
- Obtain a vehicle history report. Order a VIN vehicle-history report (e.g., Carfax or AutoCheck). This shows whether the accident appears on the vehicle’s record; many buyers check these reports when buying a used car.
- Collect comparable market data. Search for comparable vehicles (same make, model, year, mileage, condition) for sale in your region. Record listing prices and links or screenshots to support your market-value comparison.
- Hire an independent diminished value appraiser. Use a licensed appraiser or an appraiser experienced with diminished value reports in your area. Ask for a written, itemized diminished value report that explains the methodology and shows supporting comparables and adjustments.
- Ask for a written diminished value quote. The appraiser or appraisal company should produce a written dollar amount showing the calculated diminished value and the basis for the number. That is your quote to present to the insurer.
- Submit the claim package to the at-fault insurer. Send the estimate, repair invoices, photos, vehicle history, market comparables, and the independent appraisal. Demand a written response within a reasonable time.
- Negotiate or appeal. If the insurer offers less than your quote, ask for their basis for valuation, provide counter-evidence, and request re-inspection if needed. If negotiations fail, you can consider an appraisal clause (if in contract), filing a complaint with the New Jersey Department of Banking and Insurance, small-claims court, or hiring a New Jersey attorney to sue the at-fault driver/insurer.
What a strong diminished value quote includes
- Written appraisal with the appraiser’s credentials and contact information.
- Clear formula or valuation method (market-comparison approach is common).
- Photographs and vehicle history report showing the accident entry (if present).
- Repair invoices and parts receipts tied to the damage.
- Comparable listings showing pre- and post-repair market values.
- A concise executive summary stating the dollar figure sought and how it was calculated.
How appraisers calculate diminished value
Appraisers usually use one of these approaches:
- Market-comparison approach: Compare your repaired vehicle to identical vehicles without accident history and quantify the price gap.
- Damage-severity adjustment: Start with a baseline percentage of loss based on severity (minor, moderate, severe) and adjust for mileage, age, market demand, and quality of repairs.
- Cost-based approaches: Less common—focus on costs of repairs and parts, but courts and buyers prefer market-based evidence of depreciation.
If the insurer denies or undervalues your claim
- Request a written denial or explanation of the valuation methodology.
- File a complaint with the New Jersey Department of Banking and Insurance for review: https://www.state.nj.us/dobi/.
- Consider small-claims court for modest amounts, or hire a lawyer for larger claims to demand arbitration or litigation.
Timing and recordkeeping
Act promptly. Preserve all original documents, photos, and invoices. Obtain the appraisal while the vehicle and repair documentation remain current — evidence often loses persuasive value over time.
Costs you should expect
Independent appraisals cost money; expect appraisal fees and possibly inspection fees. Balance appraisal cost against likely recovery. If the diminished value is small, the cost of a full appraisal may exceed recovery; in that case, a well-documented written estimate from a reputable source may suffice.

Helpful Hints
- Take high-quality photos immediately after the crash and again after repairs.

- Get at least one independent diminished value appraisal if your expected loss is significant.
- Ask the insurer to explain any low valuation in writing and demand re-inspection if you disagree.
- Compare the cost of appraisal with the expected recovery; for small claims, consider negotiating without an appraisal.
