2.5 Common Property Policy Conditions and Clauses

Key Takeaways

  • Insured duties after loss include prompt notice, protecting property, inventory, EUO, and a sworn proof of loss (often within 60 days).
  • Appraisal resolves disputes over the amount of loss, not coverage; subrogation lets the insurer pursue negligent third parties.
  • The standard mortgage clause protects the lender even when the owner's acts void coverage and gives separate cancellation notice.
  • Vacancy beyond 60 days excludes some perils and pays other covered losses at 85%.
  • Cancellation notice is commonly 10 days for nonpayment and 30 days for other reasons, subject to state law.

Property Policy Conditions and Clauses

Conditions are the rules both parties must follow for coverage to apply. They sit in the Conditions section of the policy and in the Common Policy Conditions (IL 00 17) attached to commercial packages. The exam tests the insured's post-loss duties, the insurer's rights, and a handful of named clauses that recur on every property policy.

Insured's Duties After a Loss

The insured must: give prompt notice; protect the property from further damage (and keep records of those expenses); prepare an inventory of damaged property; permit inspection and examination under oath; cooperate; and submit a signed, sworn proof of loss, usually within 60 days of the insurer's request. Failure to perform these duties can void or reduce the claim.

Key Property Clauses

ClauseEffect
Insurable interestInsured must stand to suffer financial loss; required at the time of loss
AppraisalEither party may demand appraisal to resolve a dispute over the amount (not coverage) — each picks an appraiser, who pick an umpire
SubrogationAfter paying, insurer assumes the insured's right to recover from a negligent third party
SalvageInsurer may take damaged property after paying a total loss
AbandonmentInsured may NOT abandon property to the insurer
AssignmentPolicy cannot be assigned without insurer consent
VacancyCoverage reduced/suspended after a building is vacant 60+ days

Mortgage and Loss-Payable Clauses

The standard mortgage clause protects the lender's interest even if the insured's own acts would void coverage (e.g., arson by the owner). The mortgagee gets separate notice of cancellation (commonly 10 days), can pay premium to keep coverage in force, and is paid to the extent of its interest. A loss-payable clause is similar but used for general secured creditors and is not as protective as the standard mortgage clause.

Vacancy, Concealment, and Other Conditions

Under commercial property, a building vacant more than 60 consecutive days before a loss triggers a penalty: certain perils (vandalism, sprinkler leakage, glass, theft, water) are excluded outright, and other covered losses are paid at 85%. The concealment, misrepresentation, or fraud condition voids coverage for any insured who intentionally conceals a material fact or commits fraud. Liberalization automatically extends a broadened form to existing policyholders at no charge.

Cancellation and Nonrenewal Mechanics

Most forms allow the insured to cancel anytime. The insurer must give written notice: commonly 10 days for nonpayment and 30 days for other reasons, though state law controls. A policy in force 60+ days generally limits the insurer's cancellation grounds to nonpayment, fraud, or a substantial increase in hazard. Nonrenewal also requires advance written notice under most state codes.

Subrogation, Appraisal, and Assignment in Depth

Several standard conditions decide how disputes and recoveries are handled after a loss, and each is a reliable exam topic.

  • Subrogation - after paying, the insurer succeeds to the insured's right to recover from the at-fault party. The insured must not impair that right; a pre-loss waiver of subrogation (common in construction contracts) is allowed, but a post-loss waiver can void coverage.
  • Appraisal - when the insurer and insured agree that a loss is covered but dispute the amount, either may demand appraisal. Each side picks an appraiser, the two select an umpire, and agreement of any two sets the amount. Appraisal resolves value, not coverage.
  • Assignment - the policy generally cannot be assigned to another party without the insurer's written consent, because the insurer underwrote a specific insured. A post-loss claim payment, however, can often be assigned.

Appraisal vs. arbitration trap: Appraisal settles only the amount of a covered loss; it cannot decide whether coverage applies. A dispute over coverage goes to the courts, not the appraisal panel.

Salvage and the Abandonment Bar

When the insurer pays a total loss, it may take salvage (the damaged property) and resell it to offset the payment. Correspondingly, the insured may not abandon damaged property to the insurer and demand a total-loss payment - the no-abandonment condition prevents the insured from forcing the insurer to take unwanted property.

Loss Payment Timing and Proof of Loss

Most forms require a sworn proof of loss within a set number of days of the insurer's request and obligate the insurer to pay within a stated period (commonly 30-60 days) after reaching agreement or an appraisal award. Failure by the insured to submit timely proof can bar the claim; failure by the insurer to pay timely can trigger the state's unfair claims rules and interest.

The Mortgage Clause and Lender Protections

Two conditions decide how third parties and overlapping policies interact with a property claim.

The Standard (Union) Mortgage Clause

The standard mortgage clause gives the mortgagee independent rights: the lender is paid for its interest even if the insured's own act (arson, misrepresentation) voids the insured's coverage. In exchange, the mortgagee must notify the insurer of known hazard increases, pay premium on the insured's default if asked, and submit proof of loss. Loss payments go to the mortgagee as its interest appears, ahead of the owner.

Exam trap: Under the standard mortgage clause the lender still collects after the insured's fraud or arson; under a weaker loss-payable clause the payee's rights are derivative and fall with the insured's. Know which clause protects the lender independently.
