Diminished value claims after a Massachusetts car accident.

Can you claim diminished value in Massachusetts?

Diminished value is the gap between what your car was worth immediately before a crash and what it’s worth after it has been fully repaired. Even a well-done repair often leaves that gap, because the vehicle now carries an accident history that shows up in a title check and depresses resale value. Massachusetts treats this loss very differently depending on whose insurer you ask.

Against your own insurer, the answer is no. The Massachusetts Division of Insurance states plainly that if you file a diminished value claim with your own insurance company, there is no coverage under your policy.

Against the at-fault driver, the answer is yes, with real limits. The Supreme Judicial Court ruled in October 2021 that diminished value caused by a collision may be recoverable from the at-fault party, at least for claims involving the 2008 edition of the Standard Massachusetts Automobile Insurance Policy. A second ruling in January 2025 addressed what happens when the at-fault driver’s policy is the newer 2016 standard form instead. Either way, you’re recovering from the at-fault driver’s side of the claim, not your own, and you carry the burden of proving the loss.

Why your own insurer won’t pay it

This split between first-party and third-party diminished value claims isn’t unique to Massachusetts. A national review of diminished value law distinguishes the two categories and notes they have to be handled differently to reconcile diminished value with the principle of indemnity: your insurer’s job is to put you back where you were before the loss, not better and not worse.

In practice, your own collision coverage pays to repair the physical damage, minus your deductible, and stops there. Except in a very few states, standard auto policy language clearly excludes coverage for diminished value when the policyholder is at fault in a crash. Massachusetts isn’t one of the exceptions; the Division of Insurance’s consumer guidance confirms the exclusion applies here.

One complication worth flagging: Massachusetts insurers don’t all write identical policies. Depending on the carrier, you might be dealing with the 2008 standard policy, the 2016 standard policy, or a proprietary form the Division has separately approved. None of those forms cover your own at-fault diminished value, but the distinction matters a great deal once you’re pursuing a claim against someone else. If you want to see how your own policy’s coverages fit together before you need any of them, our guide to how car insurance works in Massachusetts walks through the standard parts.

The 2021 and 2025 SJC rulings that created third-party recovery

Before October 2021, Massachusetts had no clear rule allowing diminished value recovery at all. That changed when the Supreme Judicial Court ruled, for claims involving the 2008 standard policy, that diminished value caused by a collision may be recoverable from the at-fault party. The court put the burden of proof on the claimant to show two things: that the vehicle suffered diminished value even after being fully repaired, and the dollar amount of that loss.

In January 2025, the SJC revisited the question for at-fault drivers holding a 2016 standard policy instead of the 2008 form, in a case cataloged as Cubberley v. Commerce Insurance Company. The court held that where the at-fault driver’s policy is based on the 2016 standard policy, the insurance company itself is not required to cover claims for inherent diminished value. The ruling didn’t close the door entirely, though: the at-fault driver personally could still be held responsible for inherent diminished value if the claimant independently establishes it.

The practical upshot is that which standard policy the at-fault driver happens to carry can determine whether their insurer pays your diminished value claim directly, or whether you’re pursuing the at-fault driver personally for a loss their insurer won’t cover. The Division of Insurance advises contacting the at-fault driver’s insurer directly to find out which policy edition applies and whether it responds to diminished value at all.

The liability-limit ceiling on what you can actually collect

Even a strong diminished value claim runs into a hard ceiling: the at-fault driver’s property-damage liability limit. A third-party diminished value award is paid out of that same coverage that pays for your vehicle’s repair costs, so your repair bill and any diminished-value award have to share one limit.

For policies issued or renewed on or after July 1, 2025, Massachusetts raised its compulsory minimum for property damage to others to $30,000 per accident, up from the prior $5,000 minimum, under Chapter 275 of the Acts of 2024 amending M.G.L. c. 90. Bodily injury minimums rose to $25,000 per person and $50,000 per accident, up from the former 20/40, and PIP stayed at $8,000 per person. It’s the property-damage figure that caps a diminished value recovery. If the at-fault driver carries only the compulsory minimum, $30,000 is the entire pool available for your repair costs and diminished value combined. If your repair bill alone runs close to that number, there may be little left for diminished value no matter how well you prove it. This is one more reason your own uninsured or underinsured motorist coverage matters when the other driver is thin on liability limits; see our guide to uninsured and underinsured motorist coverage in Massachusetts for how that layer works.

Proving the loss and calculating the amount

Massachusetts gives you no formula to lean on. The claimant carries the burden to independently establish both that diminished value exists and its dollar amount, according to the Division of Insurance’s description of both SJC rulings. A national review of diminished value practice found no consistency across states in how the number gets calculated, and singled out Georgia as the only state with a clear statutory formula for first-party claims, a formula the reviewers themselves describe as not well-received. Massachusetts has nothing comparable. You’re proving a fact, not filling in a state-mandated number.

Documentation matters more here than in almost any other kind of auto claim. Repair records, the vehicle’s pre-loss condition and mileage, and comparable sales of similar unwrecked vehicles are the raw material for building that proof. Diminished value doesn’t apply to every repaired car; an older vehicle can sometimes be worth the same or more after repair because worn parts got replaced with new ones. That cuts both ways. It means insurers and courts may reasonably ask why an older car’s value dropped at all, and it means your evidence has to speak to your specific vehicle rather than a general rule of thumb.

Deadlines and where to bring the claim

A diminished value claim against an at-fault driver is a tort claim, and Massachusetts tort actions must be commenced within three years after the cause of action accrues, under M.G.L. c. 260, section 2A. That clock is the outer boundary; insurers typically want to hear from you well before that.

For smaller claims, Massachusetts small claims court carries a useful exception. Small claims are generally capped at $7,000, but the District Court’s own guidance carves out property damage from an automobile accident specifically, noting the award may exceed $7,000 in that circumstance. The filing fee for an automobile property-damage claim over $7,000 is $150, the same tier as claims between $5,001 and $7,000. That path can be worth considering for a diminished value claim that doesn’t justify hiring counsel for a full civil suit.

What this means before your next accident

Diminished value law in Massachusetts is newer and more unsettled than most drivers assume. It has been built almost entirely through two Supreme Judicial Court rulings rather than a statute, and lawmakers have separately filed bills, such as House Bill H.1070, to create an optional diminished-value coverage option that doesn’t yet exist in current law. Until something like that passes, your best protection is understanding your own policy’s liability and collision limits before you need them, since the at-fault driver’s limits determine what’s actually available to you after a crash. Our guide to Massachusetts auto insurance requirements and laws covers what compulsory coverage looks like today, and if your vehicle ends up totaled rather than merely diminished in value, the analysis shifts entirely; see how insurers value a total loss in Massachusetts.
