Diminished Value Claims in Massachusetts

How Diminished Value Works in Massachusetts

Massachusetts is unique: whether you can recover diminished value depends on which edition of the standard auto policy the at-fault driver carries. There are two forms in circulation, and they produce opposite results.

The 2008 edition of the Massachusetts Standard Auto Policy covers “amounts for which a person is legally liable because of an accident.” In McGilloway v. Safety Insurance (2021), the Massachusetts Appeals Court held that this language includes diminished value — the insurer must pay it as part of the at-fault driver’s liability coverage.

The 2016 edition, however, includes an explicit exclusion for “any decrease in value of the vehicle or any intangible loss claimed to result from it.” In Cubberley v. Commerce Insurance (January 2025), the Massachusetts Supreme Judicial Court upheld this exclusion, ruling that the 2016 form unambiguously bars DV claims.

In practice, most current policies use the 2016 form. But some drivers with long-standing policies may still be on the 2008 edition. The key question is: which form did the at-fault driver have at the time of the accident? If they have a 2008 policy, your DV claim is viable through their insurer. If they have a 2016 policy, their insurance won’t pay DV — but you can still pursue the at-fault driver personally. The underlying tort right to recover diminished value from the negligent driver still exists; the policy exclusion just means their insurance won’t cover it.

Massachusetts’ Key Court Rulings

McGilloway v. Safety Insurance Co., 100 Mass. App. Ct. 1113 (2021): The plaintiff sought diminished value from the at-fault driver’s insurer under a 2008 edition policy. The Appeals Court held that the policy’s liability coverage — “amounts for which a person is legally liable because of an accident” — encompassed diminished value. This ruling established that DV is a recoverable component of third-party property damage liability under Massachusetts law, at least where the policy language doesn’t explicitly exclude it.

Cubberley v. Commerce Insurance Co., SJC-13585 (January 2025): The Supreme Judicial Court addressed the 2016 edition of the standard policy, which added language expressly excluding “any decrease in value of the vehicle or any intangible loss claimed to result from it.” The Court held that this exclusion was unambiguous and enforceable — the insurer had no duty to pay DV. Critically, the Court noted that its ruling addressed only the insurance contract, not the underlying tort claim against the at-fault driver.

The practical outcome: ask which policy edition the at-fault driver carries. If it’s a 2008 form, you have a strong claim against their insurance. If it’s a 2016 form, you must pursue the driver directly — a more difficult path but not a legal dead end.

How to File a Diminished Value Claim in Massachusetts

Step 1: Determine the at-fault driver’s policy edition. This is the most important step in Massachusetts. Request this information in writing from the at-fault driver’s insurer. If they won’t disclose it voluntarily, you may need to file a claim to trigger their obligation to provide coverage details.

Step 2: If the 2008 form applies — file a third-party claim normally. Send a demand letter with your repair documentation, a certified diminished value appraisal, and the amount you’re claiming. Reference McGilloway (2021) if they resist.

Step 3: If the 2016 form applies — you’re filing against the driver, not the insurance. The insurer will deny your claim based on the DV exclusion. At this point, send a demand letter directly to the at-fault driver (not their insurer). They may not realize they’re personally exposed — their insurance has denied coverage, but they remain liable. Many drivers at this point pressure their insurer to settle.

Step 4: If the driver won’t pay, file in small claims court. Massachusetts has a $7,000 small claims limit. Small claims is designed for self-representation, and the procedures are straightforward. You’ll need to prove the at-fault driver’s negligence, the amount of diminished value (via your appraisal), and that you’ve been damaged. The driver can then try to force their insurer to defend them, which sometimes leads to a settlement.

Frequently Asked Questions About DV in Massachusetts

How do I find out which policy edition the at-fault driver has?

Request a copy of the declarations page and policy language from the at-fault driver’s insurer. Massachusetts policies are standardized, so the edition date will appear on the declarations page. If the insurer refuses to disclose, file a third-party claim anyway — they’ll have to respond, and the denial letter (if under the 2016 form) will cite the applicable policy language.

What if the at-fault driver has no assets — can I still recover under the 2016 form?

The 2016 form exclusion applies to the insurance contract only. If the driver has no assets to collect against, your practical recovery options are limited. However, most people have some assets or wages that can be reached. The threat of a judgment — even a small one — often motivates settlement.

Does my own uninsured motorist coverage help?

Not for property damage in Massachusetts. Massachusetts UM coverage does not extend to property damage claims. Your only path is third-party: either through the at-fault driver’s insurance (2008 form) or directly against the driver (2016 form).

How long does a DV claim take in Massachusetts?

A straightforward claim under a 2008 policy typically resolves in 6–10 weeks. Claims under the 2016 form that require pursuing the driver directly can take 3–6 months or longer, depending on whether it goes to small claims court. The 3-year SOL gives you breathing room, but don’t wait — evidence and witness memories fade.

Claim Types Available in Massachusetts

• Third-party claim — file against the at-fault driver's insurance.

Key Court Ruling for Massachusetts

McGilloway v. Safety Insurance (2021) — 2008 policy; Cubberley v. Commerce Insurance, 495 Mass. --, SJC-13594 (Jan 2025) — 2016 policy — DV recoverability depends on which policy edition the at-fault driver carries. 2008 Standard Policy (McGilloway, 2021): third-party DV IS recoverable. 2016 Standard Policy (Cubberley, Jan 2025, 6-0 SJC): DV explicitly excluded as 'any decreased value or intangible loss.' The 2016 form became mandatory for policies on/after Jan 1, 2018. Even under the 2016 form, the underlying tort right to recover DV from the at-fault driver personally still exists — but collection is harder.

What Makes Massachusetts Different

• DV recoverability depends on the at-fault driver's policy edition — 2008 form covers DV; 2016 form excludes it. Nearly all current MA policies are now on the 2016 form
• Motor vehicle property damage claims are EXEMPT from the $7,000 small claims limit (M.G.L. c. 218, § 21) — there is NO dollar cap for vehicle damage in MA small claims court
• Even under the 2016 form, the underlying tort right to recover DV from the at-fault driver personally still exists
• Modified comparative negligence with 51% bar — at 51%+ fault you recover $0

How to File a Diminished Value Claim in Massachusetts

1. Get a professional diminished value appraisal. The 17c formula (our calculator) gives you a starting point, but insurance companies will demand a certified appraisal for any claim above the 17c result.
2. Gather documentation: pre-accident photos, repair invoices, the accident report, and before/after market value comparisons.
3. Send a written demand letter to the at-fault driver's insurance company including your appraisal, documentation, and the amount you're claiming.
4. Negotiate. Insurance companies typically start low. Be prepared to go back and forth with counteroffers based on your independent appraisal.
5. If they won't settle fairly, file in small claims court.

Frequently Asked Questions

Does Massachusetts allow diminished value claims?

Yes, via third-party claim against the at-fault driver's insurance.

How long do I have to file in Massachusetts?

3 years from the accident date.

Can I file without an attorney in Massachusetts?

Yes — most DV claims fall under Massachusetts's $7000 small claims limit.

Does the 17c formula determine what I'll actually get?

No. The 17c formula is a starting point. Insurers use it as a low baseline. Independent appraisals commonly find 2–4× the 17c result. Never accept the 17c figure as the final offer without pushing back.

What if I was partially at fault for the accident?

Your recovery is reduced by your percentage of fault (comparative negligence). For example, if you were 20% at fault, your recovery is reduced by 20%.
