How Liberty Mutual approaches these claims
Liberty Mutual routinely resists third-party DV demands. In a documented May 2026 case a not-at-fault North Carolina driver whose nearly new car was rear-ended was denied repeatedly for over a year; the company would not engage with her appraiser's $5,675 report and paid that full amount only after a TV consumer reporter contacted it. Appraisers also report it anchors offers to a 17c-style formula rather than market comparables. Outcomes vary by state law more than company policy: DV is recoverable from the at-fault carrier in most states, is barred or limited first-party in states like Florida and Texas, and Georgia's Mabry rule requires DV evaluation even first-party.
The Massachusetts rules that shape the claim
McGilloway v. Safety Ins. Co., 488 Mass. 610 (2021) (inherent diminished value recoverable under Part 4 of the 2008 Standard Massachusetts Auto Policy), superseded for current policies by Cubberley v. Commerce Ins. Co., 495 Mass. 289 (Jan. 30, 2025), holding the 2016 standard policy form expressly excludes 'any decreased value or intangible loss.'
Massachusetts uses one 3-year tort limitations period for both personal injury and property damage: 'actions of tort... shall be commenced only within three years next after the cause of action accrues.' Verified against the official malegislature.gov text. There is no longer property-damage period in Massachusetts.

FAQ
Liberty Mutual in Massachusetts
Does Liberty Mutual pay diminished value claims in Massachusetts?
Massachusetts allows a not-at-fault driver to recover diminished value from the at-fault driver's liability insurer, and that applies to claims against Liberty Mutual. This carrier has a documented pattern of resisting diminished value claims. Put everything in writing, keep the certified mail receipts, and plan for escalation from the start.
How long do I have to file against a Liberty Mutual driver in Massachusetts?
Massachusetts allows 3 years from the date of the accident for a vehicle property damage claim (Mass. Gen. Laws ch. 260, § 2A). The deadline is on filing suit, not on sending a demand letter, and negotiating with an adjuster takes weeks, so start well before it.
What if Liberty Mutual denies the diminished value claim?
Get a written denial with reasons from the assigned claims representative, then ask in writing for escalation to their supervisor and then the claims manager, recording names and dates. Liberty Mutual publishes no dedicated DV appeals unit; the general claims line is 800-225-2546 and documents can be filed at secureupload.libertymutual.com. The appraisal clause sits in the Liberty Mutual policyholder's contract, so a third-party claimant normally cannot invoke it. Once internal escalation stalls, the realistic routes are a state DOI complaint and small claims court against the at-fault driver. Beyond the carrier's own process, you can file a complaint with the Massachusetts Division of Insurance, and Massachusetts's small claims court hears claims up to $7,000, which covers most vehicle diminished value amounts.
