Allstate diminished value claims in North Dakota
North Dakota is one of the few jurisdictions that does not allow the standard third-party diminished value claim, and that is true whichever carrier insured the at-fault driver. What remains against Allstate is narrow, and it is set out honestly below.

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 North Dakota is different
Unsettled but very unlikely. There are no North Dakota decisions allowing DV under an insured's own physical-damage coverage, and standard policies limit the carrier to repair cost or actual cash value. Given the Sullivan holding on the tort side, a first-party DV theory faces long odds. Treat as effectively unavailable.
What remains
Your options in North Dakota
Read the rule first
North Dakota does not allow the standard third-party diminished value claim, so the usual demand-letter route against Allstate is not available. The routes below are what remain.Check the narrow routes
North Dakota is an outlier: it effectively does NOT allow an inherent diminished value claim. N.D.C.C. § 32-03-09.1 presumes damages are reasonable repair cost plus loss of use, switching to a before/after market value measure only when restoration is impossible or impracticable. In Sullivan v. Pulkrabek the ND Supreme Court held a plaintiff who took the cost of repair had already received the full statutory measure and could not also recover diminution in value. DV is reachable only by arguing the vehicle could not be properly restored. ND's no-fault act (ch. 26.1-41) limits only bodily-injury tort claims, the DV bar comes from § 32-03-09.1.Document everything anyway
If one of the narrow routes fits your facts, it will turn on documentation: the repair invoice, the history report, and a supported valuation of the loss.
FAQ
Allstate in North Dakota
Does Allstate pay diminished value claims in North Dakota?
North Dakota is one of the few states that does not allow a standard third-party diminished value claim, against Allstate or any other carrier. Unsettled but very unlikely. There are no North Dakota decisions allowing DV under an insured's own physical-damage coverage, and standard policies limit the carrier to repair cost or actual cash value. Given the Sullivan holding on the tort side, a first-party DV theory faces long odds. Treat as effectively unavailable.
How long do I have to file against a Allstate driver in North Dakota?
North Dakota allows 6 years from the date of the accident for a vehicle property damage claim (N.D.C.C. § 28-01-16(4)). 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 Allstate denies the diminished value claim?
Step 1: put the request in writing to the assigned adjuster and ask for (a) a written denial or a written DV calculation, (b) every input value used, and (c) the name of any outside vendor that valued the loss. Step 2: if the number is low or the answer is silence, ask the adjuster in writing to escalate to their supervisor or claim team manager, and record names, titles and dates - Allstate publishes no dedicated DV appeals desk, so this front-line escalation is the real internal route. Step 3: if the adjuster stops responding, log a complaint through Allstate's general customer service channels published at allstate.com/help-support/contact - online email/chat, or the call centre on 1-800-726-6033 - and separately mail a written escalation, certified, to Allstate Insurance Company, PO Box 660636, Dallas, TX 75266, referencing the claim number. Note the limit: the appraisal clause in the auto policy belongs to Allstate's own insured, so as a third-party claimant you generally cannot invoke it. Once internal escalation is exhausted your leverage is a state Department of Insurance market-conduct complaint (which Allstate must respond to in writing) or small claims court against the at-fault driver, which forces Allstate to defend and usually produces a settlement offer. Beyond the carrier's own process, you can file a complaint with the North Dakota Insurance Department, and court remains available for the limited claims North Dakota does recognise.
