Maine Diminished Value Claims — The Complete Guide.

A Recognized Loss, and a Long Runway.

Maine treats the residual drop in your vehicle's market value after a proper repair as compensable property damage when another driver is at fault, and it has long-standing case law saying so. In Collins v. Kelley, the Maine Supreme Judicial Court held that the established rule for vehicle damage is recovery of the difference in the car's value before and after the accident, and that the cost of repairs, while an important factor, is not conclusive. Recovery is pursued against the at-fault driver's liability insurer.

So if you were rear-ended in Portland, Lewiston, Bangor, South Portland, Auburn, or Augusta and your car was properly repaired, the at-fault driver's insurer owes you the gap between your vehicle's pre-accident market value and its lower post-repair value, and Maine gives you up to six years to pursue it.

Three facts define a Maine DV claim:

1. The right is well-grounded. Maine case law (Collins v. Kelley; Moore v. Daggett) measures vehicle damage by the before-and-after value difference, with repair cost not as a ceiling, so the existence of the right is rarely the fight, the amount is.

2. The clock is long, six years. Maine's statute of limitations for property damage (and personal injury) is six years (14 M.R.S. § 752), among the longest anywhere.

3. Fault is apportioned, with a 50% bar and an equitable reduction. You recover if under 50% at fault; the jury then reduces the award in dollars as it considers just and equitable.

The Rules That Govern Maine DV Claims

Maine's framework is favorable: long-standing precedent measuring vehicle damage by the before-and-after value difference, a generous six-year window, and a modified-comparative rule with an unusual equitable reduction. The open question is the amount, which a credible appraisal is built to settle.

Insurers May Quote 17c in Maine — But It Has No Legal Force Here.

The 17c formula originated in Georgia's State Farm v. Mabry settlement and carries no statutory or precedential weight in Maine. Maine measures the loss as the difference in the vehicle's value before and after the accident (Collins v. Kelley), so an insurer that opens with a 17c-based number is offering a negotiating anchor, not applying Maine law.

That cuts in your favor. The 17c formula caps DV at a small fraction of pre-accident value and applies aggressive damage and mileage modifiers, so its output is almost always far below the true market loss a comparable-sales analysis documents. Because Maine measures the loss as the full before-and-after difference, with repair cost not conclusive, an insurer's 17c offer is simply the floor of the negotiation. Run the number so you know what they are anchoring to, then counter with market evidence of the actual loss.

Filing a Diminished Value Claim in Maine.

Maine recognizes your right to recover the value your vehicle lost from the at-fault party, with precedent behind it and a long six-year window. The process is about building credible evidence, pressing a documented demand, and not signing away the claim in a repair settlement.

1. Identify the at-fault driver and your lane. Maine DV is a third-party claim against the at-fault driver's liability insurer. First-party collision generally excludes DV, and UM coverage for DV is uncertain in Maine, so a clear at-fault, insured other driver is the foundation.
2. Do not cash a "payment in full" repair check. Payment for repairs does not include diminished value. Accepting a check marked as full settlement, or signing a broad release, can forfeit your DV claim. Keep the DV claim explicitly open from the start.
3. Complete repairs and gather documentation. The crash report, repair invoices, pre- and post-repair photographs, and a Carfax/accident-history record establish both the loss and the liability picture.
4. Establish pre-accident market value (PAMV). Use actual comparable sales from Maine markets, Portland, Lewiston, Bangor, Augusta. Local comparable sales control; book values are only a starting point.
5. Commission a USPAP-grade valuation report. Collins v. Kelley requires proof the value was diminished (repair cost alone is not conclusive), so the appraisal does double duty: it proves the loss and sets the number. The report must show comparable selection, condition and mileage adjustments, and working calculations.
6. Send a written demand with the appraisal attached. Cite Maine's before-and-after measure (Collins v. Kelley), frame the loss as the difference in value the repair could not restore, state your documented number, attach the appraisal, and set a reasonable response deadline.
7. Counter the 17c lowball with market evidence. Expect a 17c-based offer. Do not argue the formula on its own terms, replace it with your comparable-sales analysis, which reflects the actual market loss Maine recognizes.
8. Mind comparative fault. If some fault may be assigned to you, remember Maine bars recovery at 50% and reduces an allowed recovery by an amount the jury considers just and equitable. Build the liability record carefully.
9. Escalate to the Maine Bureau of Insurance if needed. The Bureau takes consumer complaints about insurer claims handling. A complaint frequently moves a stalled or unreasonably low claim.
10. Consider small claims, and use the long clock wisely. Maine small claims court handles disputes up to $6,000, a fast, attorney-optional venue. The SOL is six years (14 M.R.S. § 752), but document early regardless, evidence is freshest soon after the loss.

Documented Number, Claim Kept Open.

Maine gives you a recognized right with precedent behind it and the longest clock in the region. Three things determine how much you collect:

1. The quality of your valuation evidence. Collins v. Kelley requires proof the value dropped (repairs are not conclusive), so a USPAP-grade report with real Maine comparable sales is what satisfies the rule and beats the 17c anchor.

2. Keeping the claim open. Because a "payment in full" repair check or broad release can waive DV, the most common way Maine claims are lost is by accidentally settling them, keep the DV piece explicitly alive.

3. Fault. You recover if under 50% at fault; the jury then reduces an allowed award in dollars as it considers just and equitable, so a clean liability record protects the full number.
