Diminished value claims in Massachusetts

Law checked · General information, not legal advice

Short answer

Can I claim diminished value in Massachusetts?

It depends on the policy edition. The Supreme Judicial Court held inherent diminished value recoverable under Part 4 of the 2008 standard Massachusetts policy in McGilloway (2021), and held in Cubberley (2025) that Part 4 of the 2016 standard policy does not have to cover it. The at-fault driver can still be liable in tort for lost value you prove with individualized evidence, and you generally have three years to sue (M.G.L. c. 260, § 2A).

Who can claim diminished value in Massachusetts

  • Third-party claim against the at-fault driver's insurer: check which edition of the standard policy the driver carries. McGilloway (2021) covered the 2008 edition; Cubberley (2025) held the 2016 edition's Part 4 does not have to pay inherent diminished value.
  • Claim against the at-fault driver personally: Cubberley separates the insurer's policy obligation from what the driver owes in tort, so a proven loss in value can still be pursued against the driver.
  • The court put the burden on you: each owner must prove, with evidence about their own vehicle, that it lost value and by how much. A generic percentage will not meet that burden.
  • First-party claims under your own collision coverage are a different question, and standard policy language generally limits them to repair cost or actual cash value.

Massachusetts deadline: 3 years (M.G.L. c. 260, § 2A)

Three years for tort actions, including property damage from a collision.

Fault: M.G.L. c. 231, § 85

Modified comparative negligence: you recover if your negligence is not greater than the other party's, reduced by your percentage.

How Massachusetts law treats diminished value

McGilloway v. Safety Insurance Co., 488 Mass. 610 (2021) held that inherent diminished value damages, if adequately proved, are recoverable under Part 4 of the 2008 standard Massachusetts automobile policy.

Cubberley v. Commerce Insurance Co., SJC-13563 (Jan. 30, 2025) narrowed that: McGilloway does not provide an independent legal basis requiring insurers to cover third-party inherent diminished value claims under Part 4 of the 2016 standard policy. The court treated the insurer's policy obligation and the driver's liability in tort as separate questions.

The decision stresses individualized proof. In practice that means a written report on your car: its pre-accident value, the repair record, and market evidence of what similar cars with a reported accident sell for in Massachusetts.

Massachusetts is a no-fault PIP state for injuries, but property damage, including diminished value, is still claimed against the at-fault driver's property-damage coverage.

How insurers value a totaled car in Massachusetts

Massachusetts regulates damage appraisals more tightly than most states. Under 211 CMR 133, damage appraisals are made by appraisers licensed by the Auto Damage Appraiser Licensing Board (212 CMR 2.00), and when repair cost plus salvage may exceed actual cash value, a licensed appraiser completes a total-loss report.

When a car may be a total loss, 211 CMR 133 lists the factors the insurer must consider for actual cash value: the retail book value of a vehicle of like kind and quality, the price paid plus prior improvements less depreciation, any decrease from prior unrelated damage, and the actual cost of buying an available vehicle of like kind and quality.

Salvage value is based on bids from licensed salvage companies, and the appraiser must tell you who bid, how much, and when the offer expires. Ask for those details in writing.

The appraisal clause in Massachusetts

The Massachusetts standard auto policy includes an appraisal procedure for disputes about the amount of a covered physical-damage loss under your own coverage. Read the version of the policy you hold, since the standard form has been revised over the years.

Be precise about roles. A damage appraisal in Massachusetts must be written by a licensed Massachusetts auto damage appraiser. Our report is a market-value and diminished-value valuation. It is not a licensed Massachusetts damage appraisal, and we will tell you if your dispute needs one.

What else matters in Massachusetts

  • Massachusetts complaints about claim handling go to the Division of Insurance.
  • Small claims in Massachusetts cover cases up to $7,000, which covers many diminished-value disputes without a lawyer.
  • Keep the licensed appraiser's report the insurer produced. Its parts and labor lines are the starting point for measuring how severe the damage was.

What to gather for a Massachusetts diminished value claim

  • The final repair invoice, with every supplement
  • Photos of the damage before repair, and of the car after repair
  • Proof of the car's condition before the crash: service records, earlier photos, mileage, trim and options
  • A diminished value appraisal: a written valuation of what the accident did to your car's resale value
  • The crash report and the claim number on the at-fault driver's policy

For the appraisal, a formula figure is not market evidence. What holds up is a comparison of your car against Massachusetts-market listings with and without accident history.

How to ask the at-fault insurer in writing

  1. Get the claim number and adjuster for the property-damage claim on the at-fault driver's policy. It is a separate claim from anything on your own policy.
  2. Write a short letter or email: the date of loss, the claim number, your car (year, make, model and VIN), that you are claiming diminished value, the amount, and how it was worked out.
  3. Attach the appraisal, the final repair invoice and the photos. Keep the originals.
  4. Ask for a written response, and if the insurer disagrees, ask for its own valuation in writing.
  5. Send it in a way you can prove, such as email to the adjuster plus certified mail, and keep a copy of everything you send and receive.
  6. Watch the 3-year deadline under M.G.L. c. 260, § 2A. An open insurance claim does not stop it.

You send the request yourself. If it needs to go further, that is a decision for you or your attorney. General information, not legal advice.

2019 Tesla Model 3 total loss

$17,262 → $29,155

Our founder's own total-loss claim. The insurer's first valuation was $17,262. After a dispute built on comparable sales and a documented valuation, the agreed value was $29,155. That is a total-loss case, not a diminished-value case, and every claim turns on its own vehicle, market and insurer. Read the case.

Massachusetts diminished value FAQ

Is diminished value recoverable in Massachusetts?
It depends on the policy. McGilloway (2021) allowed it under Part 4 of the 2008 standard policy, but Cubberley v. Commerce Insurance Co. (2025) held the 2016 standard policy's Part 4 does not have to cover it. The at-fault driver can still owe proven lost value in tort.
What proof does Massachusetts require for diminished value?
Individualized proof that your vehicle lost value and how much. That usually means a written valuation of your car built from its repair record and Massachusetts market evidence, not a flat percentage.
Do I need a licensed appraiser in Massachusetts?
Damage appraisals (the cost to repair) must be written by an appraiser licensed by the Auto Damage Appraiser Licensing Board. A market-value or diminished-value valuation is a different document. Ask whoever prepares your report which one you are getting.
How long do I have to bring a diminished value claim in Massachusetts?
Generally three years for tort claims under M.G.L. c. 260, § 2A. Start the insurance claim as soon as repairs are complete.
