When a property insurance claim reaches an impasse over value, not over whether the loss is covered, but over what it is actually worth, most policies include a built-in remedy: the appraisal clause. Invoking it correctly matters. A demand made informally, sent to the wrong party, or missing a policy-required element can create unnecessary delay or, in rare cases, give the other side grounds to challenge it later. This guide walks through what the appraisal clause says, when it makes sense to use it, and the specific steps for invoking it properly.
What the Appraisal Clause Actually Says
Most homeowners, commercial, and dwelling property policies include an appraisal provision, typically found in the conditions section. The exact wording varies by carrier and by state, but the core mechanics are consistent: if the policyholder and insurer agree a loss is covered but disagree on the amount of loss, either party can make a written demand for appraisal. Once invoked, each side selects a competent, disinterested appraiser, and the two appraisers work toward an agreed value or, if they cannot agree, jointly select a neutral umpire to break the tie.
It is worth reading your policy's exact appraisal language before invoking it, since some policies specify a deadline for invoking appraisal, require a particular format for the demand, or spell out how appraiser and umpire costs are split. The clause is a contract term, and the process it describes controls exactly how appraisal unfolds for your specific claim.
When It Makes Sense to Invoke Appraisal
Appraisal only resolves disputes over the dollar value of a loss that both sides already agree is covered. It does not decide coverage disputes, such as whether a specific cause of loss falls within the policy's terms or whether an exclusion applies. If the disagreement is about whether something is covered at all, appraisal is the wrong tool for that part of the dispute.
Appraisal tends to make the most sense once negotiations between the policyholder, or their public adjuster, and the insurance company have genuinely stalled on scope or price, when the gap between the two valuations is significant enough to justify the appraisal cost, and when both sides are working from complete documentation rather than a preliminary estimate that has not been fully developed yet. Invoking appraisal too early, before documentation is complete, can lock in a number that does not reflect the full scope of the loss.
Step 1: Review Your Policy's Appraisal Language
Before drafting anything, pull your complete policy and locate the appraisal clause, usually listed under "Conditions." Confirm three things: whether there is a deadline for invoking appraisal after a disagreement arises, what the policy requires the written demand to include, and how appraiser and umpire fees are allocated between the parties. Some policies are silent on timing, but many specify a window, and missing it can complicate your ability to invoke the clause later.
Step 2: Put Your Demand in Writing
The appraisal demand should be a clear, written notice sent to the insurance company (or, if the insurer is invoking, sent to the policyholder) stating that appraisal is being invoked under the policy's appraisal provision, identifying the claim number and date of loss, and naming the appraiser you have selected. Send it by a method that creates a paper trail, certified mail or email with delivery confirmation, and keep a copy for your file. A verbal request or an informal mention during a phone call with the adjuster does not satisfy most policies' appraisal provisions.
Step 3: Select a Competent, Impartial Appraiser
Each side selects its own appraiser, and most policies require that appraiser to be competent and impartial, meaning experienced in evaluating the type of property and loss at issue, and free of a financial stake in the outcome beyond their fee. This is where the role sometimes gets misunderstood: an appraiser's job is to reach a defensible, methodologically sound valuation, not to advocate for the highest possible number on behalf of whoever hired them. Catalyst's insurance appraisal services are structured around that independence, since our appraisers can be retained by either a policyholder or an insurer for the same reason: the process only holds up if both sides are working from an honest, defensible number.
Step 4: What Happens After You Invoke
Once appraisal is invoked and both sides have selected appraisers, the two appraisers exchange information, inspect the property, and attempt to agree on the value of the loss. If they reach agreement, that figure becomes the resolved value and the claim moves forward for payment. If they cannot agree on every point, they jointly select a neutral umpire, and any two of the three, the two appraisers or one appraiser and the umpire, can sign a binding award. For a full walkthrough of what happens once both sides have selected appraisers, see our guide to how the insurance appraisal process unfolds.
Appraisal generally moves faster than litigation, often resolving in weeks to a few months, and each side typically pays its own appraiser while splitting the umpire's fee, though the exact allocation depends on your policy language.
What Documentation Strengthens Your Position
The appraisers on both sides can only work with what they are given. A thorough file, complete photos and video from the initial inspection, a detailed scope of repairs, contractor bids, receipts for any emergency mitigation, and copies of every prior estimate exchanged with the carrier, gives your appraiser a real basis for a defensible number instead of a rough approximation. Gaps in documentation do not disappear during appraisal; they simply become questions the other appraiser, or the umpire, has to resolve without complete information, which tends to work against whichever side left the gap.
It also helps to organize the file chronologically, from the date of loss through every communication with the carrier, so your appraiser can quickly identify where the two valuations diverged and why. Retaining an appraiser before the demand is sent, rather than after, gives them time to flag missing documentation while there is still an opportunity to gather it.
Appraisal on Commercial and Large-Loss Claims
Commercial property disputes, hotels, apartment complexes, retail centers, and industrial facilities, tend to involve more moving parts than a residential claim: business interruption calculations, multiple buildings or units, and repair scopes that touch specialized systems. Appraisal still works the same way procedurally, but the appraiser's qualifications matter even more, since a generalist with no background in commercial construction or business interruption accounting can slow the process down or produce a valuation that does not hold up under scrutiny.
Attorneys representing either a commercial policyholder or an insurer in a valuation dispute should also confirm that the appraiser and any umpire involved understand how appraisal interacts with the broader claim file, since large commercial losses sometimes involve coverage questions running in parallel with the value dispute that appraisal alone will not resolve.
Common Mistakes When Invoking Appraisal
Waiting too long. Some policies impose a deadline for invoking appraisal after a dispute arises. Waiting too long to invoke, or waiting until a lawsuit is already underway, can complicate or foreclose the option entirely.
Invoking before documentation is complete. Appraisal works best when both appraisers have a full record to evaluate. Invoking before photos, estimates, and contractor evaluations are gathered can shortchange the outcome.
Sending an informal demand instead of a written one. A phone call or an email that does not clearly invoke the appraisal clause, name an appraiser, and reference the policy provision may not satisfy the policy's requirements.
Selecting an appraiser without relevant expertise. An appraiser needs genuine experience with the type of property and damage at issue. A generalist unfamiliar with, for example, commercial business interruption losses or complex roofing systems can slow the process down.
Assuming appraisal resolves coverage disputes. Appraisal settles the amount of a covered loss. It does not determine whether a loss is covered in the first place, and treating it as a substitute for a coverage argument is a common and costly misunderstanding.
Frequently Asked Questions
Can I invoke appraisal if my whole claim was denied? Generally, no. Appraisal is built for value disputes on losses both sides agree are covered. If the entire claim was denied on coverage grounds, that is a different kind of dispute.
Who pays for the appraiser and the umpire? Each side typically pays its own appraiser's fee. The umpire's fee, when one is needed, is usually split evenly between the policyholder and the insurer, though your specific policy language controls the exact allocation.
Is the appraisal award final? Yes. A signed award from any two of the three participants, the two appraisers or one appraiser and the umpire, is binding on both the policyholder and the insurance company.
