Allstate diminished value claims in Michigan

How Allstate approaches these claims

Third-party DV outcomes with Allstate are driven almost entirely by the law of the state where the crash happened, because Allstate publishes no DV position at all. Verified: a crawl of Allstate's own sitemap (allstate.com/sitemap-main.xml) returns zero pages mentioning diminished value, and its consumer article on third-party claims (allstate.com/resources/car-insurance/third-party-insurance-claims) lists only repairs, transportation and medical expenses as recoverable - DV is never mentioned. So there is no carrier-published formula, standard or entitlement to point to. What IS documented at the carrier level is the opposite direction: Allstate's own auto policy contains an express diminished-value exclusion. In Watkins v. Allstate Prop. & Cas. Ins. Co., 2024 WL 135458 (5th Cir. Jan. 12, 2024), the Fifth Circuit quoted the Allstate provision excluding "any decrease in the property's value, however measured, resulting from the loss and/or repair or replacement," and enforced it - even against an uninsured/underinsured motorist property damage claim, holding there is no such thing as an underinsured vehicle for DV purposes once statutory minimum limits are met. Practical effect: first-party and UM-PD routes to DV against Allstate are closed wherever that form is used and the state permits the exclusion. Your claim must be a third-party tort claim against Allstate as the AT-FAULT driver's carrier, where the policy exclusion does not apply and state negligence law governs the measure of damages. State variation is decisive. Georgia is the strongest jurisdiction: State Farm Mut. Auto. Ins. Co. v. Mabry, 274 Ga. 498, 556 S.E.2d 114 (2001) held that "loss" includes post-repair loss of value and required insurers to assess and offer DV even on FIRST-party physical damage claims. Mabry is a State Farm case and binds State Farm directly, but it is a construction of Georgia insurance law and the Georgia Insurance Department applied it industry-wide, so Georgia claimants can invoke it against Allstate as well - and Georgia's separate third-party rule (Perma Ad Ideas of Am., Inc. v. Mayville, 158 Ga. App. 707 (1981)) lets a not-at-fault owner recover repair cost plus post-repair depreciation. North Carolina is likewise claimant-friendly. Michigan and North Dakota are cited by appraisal firms as unfavorable. LOWER CONFIDENCE on Allstate's actual negotiating behaviour: the only carrier-specific account is from DVCHECK, a commercial DV appraisal firm (post dated 31 March 2025), which says Allstate "will pay a diminished value claim in most instances," is "generally one of the better companies when it comes to paying diminished value claims," and "will typically make an offer after you submit a professional appraisal." That is a vendor with a commercial interest in selling appraisals, not the carrier or a regulator - treat it as directional only. On the evidence available, the honest summary is: pays negotiated amounts off a submitted appraisal where state law clearly allows third-party DV, offers nothing proactively, and relies on a contractual exclusion to shut the door on first-party and UM routes.

Why Michigan is different

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.
