Liberty Mutual diminished value claims in Michigan

Michigan is one of the few states that does not allow a standard third-party diminished value claim, against Liberty Mutual or any other carrier. No. An insurer's obligation to 'repair or replace' does not require payment for post-repair diminution in value where the policy expressly limits coverage to the lesser of actual cash value or cost of repair. Driscoll v. State Farm Mut. Auto. Ins. Co., 227 F. Supp. 2d 696 (E.D. Mich. 2002). Michigan collision policies carry that limitation.

Michigan allows 3 years from the date of the accident for a vehicle property damage claim (Mich. Comp. Laws § 600.5805(2)). The deadline is on filing suit, not on sending a demand letter, and negotiating with an adjuster takes weeks, so start well before it.

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 Michigan Department of Insurance and Financial Services (DIFS), and court remains available for the limited claims Michigan does recognise.
