2.5 Common Property Policy Conditions and Clauses

Key Takeaways

  • Conditions set duties and procedures; breaching duties after a loss (notice, proof of loss within 60 days, protect property) can defeat a claim.
  • Appraisal settles disputes over the amount of loss, never over whether coverage applies.
  • Insurable interest must exist at the time of loss for property; commercial vacancy beyond 60 days cuts coverage (85% payout, several perils excluded).
  • The standard mortgage clause protects the lender even if the insured's act voids the policy; the open clause does not.

Conditions Are the Rules of the Deal

Conditions are the provisions that spell out the duties of the insured and insurer and the procedures for handling a loss. They are not coverage grants, but a breach can void or reduce a claim. ISO property forms carry these in the Common Policy Conditions (IL 00 17) and form-specific conditions sections. The exam expects you to recognize each condition by its function.

Duties of the Insured After a Loss

Most property forms require the insured to:

  • Give prompt notice of the loss to the insurer or agent.
  • Protect the property from further damage and keep records of expenses.
  • Provide an inventory of damaged property and a signed, sworn proof of loss, usually within 60 days of the insurer's request.
  • Cooperate, submit to examination under oath, and exhibit the damaged property.

Failure to perform these duties can be grounds to deny the claim.

Key Loss-Adjustment Conditions and Clauses

Condition / ClauseWhat It Does
SubrogationInsurer recovers from the at-fault third party after paying the insured
SalvageInsurer takes title to damaged property it has paid for and may resell it
AppraisalEither party may demand appraisal when they disagree on loss amount (not coverage)
AbandonmentInsured may not abandon property to the insurer
Loss PayableNames a lender/lienholder to receive payment
Mortgagee (Standard Mortgage)Protects the lender even if the insured's act voids coverage

Trap: Appraisal resolves value disputes, not coverage disputes; if the carrier denies coverage entirely, appraisal does not apply.

Cancellation, Nonrenewal, and Assignment

Property conditions govern how the contract ends or transfers:

  • Cancellation — the insured may cancel anytime; the insurer must give written notice, commonly 10 days for nonpayment and 30 days for other reasons (state law controls the exact periods).
  • Nonrenewal — the insurer declines to renew at expiration, again with advance written notice.
  • Assignment — the policy may not be transferred to a new owner without the insurer's written consent, because underwriting attached to the original insured.

Return premium on insurer-initiated cancellation is computed pro rata (full unearned share); insured-initiated cancellation may be short-rate (a penalty is retained).

Insurable Interest, Vacancy, and Concealment

  • Insurable interest must exist at the time of loss for property insurance (unlike life, where it must exist at inception). No interest, no recovery.
  • Vacancy clause — commercial property left vacant beyond 60 consecutive days suffers reduced coverage: vandalism, sprinkler leakage, glass breakage, water damage, and theft are excluded, and other losses are paid at 85%.
  • Concealment, Misrepresentation, or Fraud — a material misstatement or concealment voids coverage. Material means it would have changed the insurer's underwriting decision.

The Standard Mortgage Clause in Action

The standard (union) mortgage clause is heavily tested. If the insured commits an act that voids the policy (such as arson or fraud), the mortgagee is still protected and can collect up to its insurable interest, then assigns its rights to the insurer via subrogation.

  • The mortgagee receives its own notice of cancellation (typically 10 days).
  • The mortgagee must pay premium if the insured does not.

Contrast this with the older open (loss-payable) mortgage clause, where the lienholder's rights rise and fall with the insured's — if the insured voids the policy, the lender collects nothing.

Appraisal vs. Arbitration vs. Suit

When the parties agree there is coverage but disagree on the amount, the appraisal condition governs: each side names a competent appraiser, the two select an umpire, and an agreement by any two of the three sets the loss amount. Appraisal resolves value, never coverage. If the dispute is whether the loss is covered at all, appraisal does not apply and the insured must sue. The suit against the insurer condition typically requires the insured to have complied with all policy terms and to file within the policy's contractual limitation period.

Mortgage Clause, Vacancy, and Assignment

The standard (union) mortgage clause protects the mortgagee even when the insured's own acts (such as concealment or increasing the hazard) would void the named insured's coverage; the mortgagee gains independent rights, must pay premium on request, notify the insurer of hazard changes, and the insurer that pays the mortgagee gains subrogation against the borrower.

A vacancy condition cuts coverage for certain perils (vandalism, glass breakage, water, theft) and reduces other payments by a stated percentage (commercial BPP: 15%) once a building is vacant beyond 60 consecutive days. Assignment of the policy requires the insurer's written consent because insurers underwrite the specific insured, not the property alone.

Conditions Quick-Reference

ConditionWhat It Governs
Duties After LossNotice, protect property, proof of loss, cooperate
AppraisalDisputes over amount, not coverage
SubrogationInsurer inherits recovery rights; insured must not impair
Other InsurancePro rata, contribution by equal shares, or excess
SalvageInsurer's right to damaged property it pays for
AbandonmentInsured may not abandon property to the insurer
Loss PaymentTime within which insurer must pay after agreement

Concealment, Misrepresentation, and Fraud as Conditions

Most property forms include a "Concealment, Misrepresentation or Fraud" condition voiding coverage if any insured intentionally conceals or misrepresents a material fact, engages in fraudulent conduct, or makes false statements relating to the insurance, whether before or after a loss.

Because it reaches "any insured," the innocent co-insured is not always protected — a distinction many states soften by statute but the model condition does not. Pair this with the vacancy and increase-in-hazard conditions, which let the insurer reduce or suspend coverage when the insured changes the risk without notice.
