Your car gets hit, the body shop restores it to like-new condition, and it drives perfectly again. But the vehicle is now worth less than it was the day before the crash, because it carries a documented accident history that buyers can see. A well-repaired car with a collision on its record still sells for less than an identical car without one. That lost value is called diminished value, and it is a real financial loss that most drivers never claim.
Massachusetts recognizes diminished value, but the question of who has to pay for it has changed in recent years, and the rules are not intuitive. Two decisions from the Massachusetts Supreme Judicial Court reshaped this area of the law, and the answer today depends on whose insurance is involved and what you are able to prove.
This article explains what diminished value is, how recent Massachusetts court rulings changed who owes you, and how to document a claim. Importantly, diminished value is a property claim that is separate from any claim for your injuries, and it is one of the most overlooked losses after a crash.

Even when a body shop restores your vehicle to its pre-accident condition, the car can be worth less on the open market simply because it now has a documented accident history. This lost market value is known as inherent diminished value. Massachusetts courts have defined it as the difference between the market value of a vehicle immediately before a collision and the vehicle's market value after the collision and subsequent repairs, even when those repairs fully restore the vehicle to its pre-accident condition. A buyer who sees a crash on a vehicle history report will typically pay less, and that gap is your loss.
The Three Types of Diminished Value
Inherent diminished value is the loss that remains after quality repairs, caused by the accident history itself. It is the type most commonly claimed and the one Massachusetts courts have addressed. Immediate diminished value is the difference in the vehicle's value right after the crash, before any repairs are made. Repair-related diminished value is the additional loss that results when repairs are incomplete or substandard. In Massachusetts, the case law and the disputes with insurers have centered on inherent diminished value.
When Diminished Value Applies
A diminished value claim generally applies when your vehicle was damaged and then repaired, not when it was declared a total loss. If the car is totaled, you are instead paid its actual cash value. Diminished value tends to matter most on newer vehicles, low-mileage vehicles, and models that hold their value well, because those cars have the most value to lose in the first place.
Massachusetts recognizes diminished value, but who has to pay depends on whose policy is involved and which version of the standard auto policy applies. Two Supreme Judicial Court decisions define the current landscape.
Your Own Insurer (First-Party Claims)
If you file under your own collision coverage, diminished value is generally not covered. Standard Massachusetts auto policies typically exclude it, unless your specific policy provides that coverage. As a result, most drivers cannot recover diminished value from their own insurance company.
The At-Fault Driver's Insurer (Third-Party Claims)
This is where the law recently shifted. In McGilloway v. Safety Insurance Company (2021), the Supreme Judicial Court held that under the 2008 edition of the Standard Massachusetts Automobile Insurance Policy, an at-fault driver's insurer could be required to pay inherent diminished value. Insurers then revised the policy language. In Cubberley v. Commerce Insurance Company (2025), decided in a unanimous ruling on January 30, 2025, the Supreme Judicial Court held that the 2016 edition of the standard policy does not provide coverage for third-party inherent diminished value claims. Because most policies in force today are based on the 2016 edition, the at-fault driver's insurer is generally not required to pay diminished value.
The At-Fault Driver Personally
Even under the 2025 ruling, the court left an important door open. The at-fault party can still be held responsible for inherent diminished value if that loss can be independently established. In other words, the claim may shift from the insurer to the at-fault driver, and the burden falls on you to prove both that your vehicle lost value after being fully repaired and the amount of that loss. This is exactly why thorough documentation is essential.
Because the burden of proof is on you, a diminished value claim rises or falls on the strength of your evidence. A well-supported claim usually includes a professional diminished value appraisal from a qualified independent appraiser, establishing your vehicle's value before the accident and its reduced value after repair. It also includes the full repair estimate and final invoices showing the nature and extent of the damage, proof of the vehicle's pre-accident condition and value such as service records and comparable market listings, the vehicle history report that now reflects the accident, and photographs of the damage and the repairs performed.
Act promptly. Evidence is easiest to gather soon after the crash, while records are complete and the details of the damage and repairs are fresh. The longer you wait, the harder it becomes to prove what your vehicle was worth before it was hit.
How a Diminished Value Claim Differs From Your Injury Claim
A diminished value claim is a property claim, and it is separate from any claim for your injuries. The two follow different paths. Your injury claim in Massachusetts generally runs first through no-fault Personal Injury Protection benefits, and to pursue pain and suffering against an at-fault driver you must meet the state's tort threshold under Massachusetts General Laws Chapter 231, Section 6D, which requires medical expenses over $2,000 or a serious injury. A diminished value claim has no such threshold. It is measured by the lost market value of your vehicle and proven with appraisals and market data rather than medical records.
Both types of claim are subject to the state's modified comparative negligence rule under Massachusetts General Laws Chapter 231, Section 85, so if you were partly at fault for the crash, your diminished value recovery is reduced by your share of the blame. And like other claims arising from a collision, a claim for property damage must generally be brought within three years under Massachusetts General Laws Chapter 260, Section 2A.
If Your Vehicle Was Damaged in a Massachusetts Crash
Diminished value is real money, and it is one of the most overlooked losses after an accident. If you were hurt in the same crash, your property losses, including diminished value, can be pursued alongside your injury claim. The recent changes in Massachusetts law make it more important than ever to document the loss carefully and to identify exactly who is responsible for paying it. Kiley Law Group investigates every crash thoroughly, gathering police reports, repair records, and the evidence needed to pursue the full value of your claim.
