The appraisal clause in commercial property disputes
How the appraisal clause settles disagreements over the amount of a property or income loss, what it cannot decide, and Texas and Florida rulings on causation.
The appraisal clause is a property policy's built-in way to settle a disagreement about how much a covered loss is worth. Either side can demand it in writing; each picks an appraiser, the appraisers pick an umpire, and any two of the three can set a binding amount. Appraisal decides the amount of loss. It does not decide whether the policy covers the loss, and the insurer keeps its right to deny the claim afterward.
For a business with a large fire, storm or water loss, appraisal can end a standoff over repair scope or lost income in months rather than the years a lawsuit takes. It can also backfire if used too early or on the wrong question.
What the standard form says
In the ISO building and personal property form (CP 00 10 10 12; see commercial property insurance: what it covers and what it doesn't), the appraisal condition reads in substance as follows. If you and the insurer disagree on the value of the property or the amount of loss, either may make written demand for an appraisal. Each party selects a competent and impartial appraiser. The two appraisers select an umpire; if they cannot agree, either may ask a judge of a court with jurisdiction to choose one. The appraisers state separately the value of the property and the amount of loss. If they fail to agree, they submit their differences to the umpire, and a decision agreed to by any two is binding. Each party pays its own appraiser and the two split the other expenses of the appraisal and the umpire equally. The condition closes by saying that having an appraisal does not take away the insurer's right to deny the claim.
The business income form (CP 00 30 10 12; see documenting a business interruption claim, from day one to final payment) has a parallel clause covering a disagreement about the amount of net income and operating expense or the amount of loss. The loss payment condition of CP 00 10 ties payment to appraisal: the insurer pays within 30 days after receiving the sworn proof of loss (see the sworn proof of loss: what it is, when it's due and how to prepare it) if there is agreement on the amount or an appraisal award has been made.
Other forms differ. FEMA's Standard Flood Insurance Policy General Property Form (see Commercial flood insurance: NFIP limits and private options) (the October 2015 edition on FEMA's site) requires each party to choose an appraiser within 20 days after a written request and gives the appraisers 15 days to agree on an umpire. Carrier forms vary: some add time limits to name an appraiser, require appraisers to be "disinterested" or exclude appraisal where coverage or causation is disputed. Read yours.
What appraisal can and cannot decide
Appraisal answers questions like: how many square feet of roof were damaged, whether a boiler can be repaired or must be replaced, what the replacement cost of the inventory is, what income the business would have earned. It does not construe the policy. Whether an exclusion applies, whether a limit or sublimit caps recovery, whether the claim was reported on time and whether the insurer acted in bad faith (insurer bad faith: what it is and the remedies) are for a court.
The hard cases are those where cause of damage and amount of loss overlap, for example storm damage versus long-standing wear. Courts disagree, and the rule in your state matters.
- Texas (see Texas). In State Farm Lloyds v. Johnson, 290 S.W.3d 886 (Tex. 2009), the Supreme Court of Texas held that setting the amount of loss necessarily involves some causation element, because appraisers must separate damage from the claimed event from damage caused by everything else, and that appraisals should generally go forward without early court intervention. On May 8, 2026, in In re ACE American Insurance Co., No. 25-0461, the court applied that rule to a commercial property claim: a ruptured fire-suppression water line under a Dallas food-distribution warehouse. The insurers had paid about $1.2 million on the mold claim and the insured said the $10 million mold sublimit applied. The court held that dispute was over the amount of loss and ordered the trial court to compel appraisal. It also held that an insurer's alleged bad faith in handling a claim is not an exception to enforcing an appraisal clause. Texas recognizes illegality and waiver as the exceptions, and the court left any remaining coverage questions for the court after appraisal. (Opinion.)
- Florida (see Florida). In Johnson v. Nationwide Mutual Insurance Co. (Fla. Sept. 26, 2002), the Supreme Court of Florida held that causation is a coverage question for the court when the insurer wholly denies that there is a covered loss, and an amount-of-loss question for the appraisal panel when the insurer admits a covered loss and disputes its amount. (Opinion on FindLaw.)
The two states agree that appraisers set the amount and judges decide liability; they differ on how much causation work is part of setting the amount. Other states fall on both sides, and some carrier forms say the clause is unavailable when causation or coverage is disputed.
How the process runs
- Disagree on the amount. Both sides have stated positions (the insurer's estimate and your documented claim). Appraisal is for a real gap, not a claim with no estimate yet.
- Written demand. Send it to the claims contact and keep proof of delivery. Check the policy for deadlines to name an appraiser.
- Choose a competent, impartial appraiser. Look for experience with the loss type: a commercial roofing estimator, a restoration contractor, a forensic accountant for income. Ask about conflicts and about fees; an appraiser paid a share of the award invites a challenge to the "impartial" requirement in some states.
- Appoint an umpire. The two appraisers choose; if not, a court does under the policy's terms.
- Exchange documents and inspect. Appraisers visit the property and review estimates, financial records and photographs.
- Award. If the appraisers agree, that is the amount. If not, the umpire decides the difference, and an award agreed to by any two is binding as to the amount.
- Payment. The insurer applies the deductible, coinsurance and prior payments, and pays under the loss payment condition. Replacement cost holdbacks are still subject to the replacement-cost terms (replacement cost vs actual cash value for business property); see the commercial property claim process, step by step.
What it costs
Each side pays its own appraiser, and the umpire and other expenses are split equally. Your own attorney, public adjuster and experts are separate. Appraiser and umpire fees are real costs, so compare them to the amount in dispute: if the gap between the parties is small, appraisal may cost more than it saves.
A hypothetical example
Say a distribution warehouse has a burst sprinkler line. The insurer's estimate for repair is $380,000 and the owner's contractor's is $610,000. The gap is in the scope of flooring replacement, the number of electrical panels to replace, and the method for drying the slab. The owner demands appraisal. The owner's appraiser values the loss at $590,000 and the insurer's appraiser at $400,000. They cannot agree and submit the differences to the umpire, who sets $520,000, which the owner's appraiser signs. The award of $520,000 sets the amount of loss, and the insurer pays that figure less the deductible and what it already paid. Each side bears its own appraiser's fee and half of the umpire's. The insurer's reservation of rights on a separate mold question stays unresolved, because appraisal did not decide coverage. These numbers are invented to illustrate the mechanism.
When appraisal helps and when to wait
| Appraisal tends to help | Pause first |
|---|---|
| The dispute is about price, scope or the extent of damage | The real dispute is whether the loss is covered at all |
| The facts are documented and the cause is not contested | Your documentation is incomplete or the sworn proof of loss is not filed |
| You want a faster, cheaper route than litigation | You have claims you want a court to decide, such as unfair claims practices |
| Both sides have credible technical support | An appraiser's fee would exceed the amount in dispute |
Delay can waive the right to demand appraisal in some states; the Supreme Court of Texas measures reasonableness from the point of impasse, when further negotiation appears futile. Speak with a coverage attorney before demanding or refusing appraisal on a large claim, especially because the award is hard to undo. Courts set awards aside only on narrow grounds. In Texas, for example, those include fraud, accident or mistake, or an award made without authority. See coverage litigation and declaratory judgment actions: when you and your insurer end up in court, mediation and arbitration in insurance disputes and what to do when your business insurance claim is denied.
Key takeaways
- The appraisal clause settles disagreements over the amount of loss; the insurer keeps its right to deny coverage, and courts decide liability.
- Each side pays its own appraiser and splits the umpire and other costs; an award agreed to by any two of the three is binding on the amount.
- Whether appraisers may decide causation varies: Texas allows the causation work needed to set the amount, while Florida sends causation to the court when the insurer wholly denies coverage.
- In May 2026 the Supreme Court of Texas held that alleged bad-faith claims handling does not excuse a party from appraisal.
- Use appraisal for real price and scope gaps, with documentation ready and an attorney's advice on larger claims.
