Homeowners Conditions and Duties After Loss

Key Takeaways

  • Dwelling losses settle at replacement cost only if the insured carries at least 80% of full replacement cost; otherwise the greater of ACV or the (Did/Should) x Loss coinsurance formula applies.
  • The insured's duties after loss include prompt notice, protecting property, preparing an inventory, submitting to examination under oath, and filing a sworn proof of loss within 60 days of request.
  • Appraisal resolves disputes over the AMOUNT of loss only - never coverage; two appraisers select an umpire and any two agreeing sets the amount.
  • Suit against the insurer must be brought within two years; the insured may never abandon property to the insurer.
  • The mortgagee clause protects the lender even when the insured's own act would void coverage, and concealment or fraud voids the policy.

Policy Conditions: The Rules of Engagement

Conditions are the contractual rules that govern how Section I and Section II respond. The national exam tests conditions heavily because they decide whether a claim is paid in full, paid in part, or denied. The ISO Homeowners form groups conditions into Section I Conditions, Section II Conditions, and Conditions Applicable to Both Sections. Learn the numeric triggers and the difference between an insured's duties (what the insured must do) and the insurer's options (what the company may do).

Loss Settlement and Coinsurance (Section I)

Dwelling losses (Coverage A) settle on a replacement cost basis only if the insured carries at least 80% of full replacement cost at the time of loss. If the insured carries less than 80%, the insurer pays the greater of actual cash value (ACV) or the coinsurance formula:

Payment = (Did / Should) x Loss - Deductible

Where Did = limit carried and Should = 80% of replacement cost.

Worked example: Replacement cost = $400,000. Required 80% = $320,000. Insured carries only $240,000. A partial loss of $100,000 occurs; deductible $1,000.

  • Ratio = $240,000 / $320,000 = 0.75
  • Indemnity = 0.75 x $100,000 = $75,000
  • Less deductible = $74,000 paid; the insured absorbs the $25,000 coinsurance penalty plus the deductible.

Note that personal property (Coverage C) settles at ACV unless a replacement-cost endorsement (HO 04 90) is attached. ACV = replacement cost minus depreciation.

Duties After Loss (Section I)

After a loss, the insured must satisfy specific duties as a condition of recovery. Failure can void or reduce a claim. The duties:

  1. Give prompt notice to the insurer or agent.
  2. Notify the police in case of theft.
  3. Notify the credit card/fund transfer company for those losses.
  4. Protect the property from further damage; make reasonable temporary repairs (and keep records of expenses).
  5. Cooperate with the investigation and settlement.
  6. Prepare an inventory of damaged personal property.
  7. Exhibit the damaged property as often as reasonably required.
  8. Submit to examination under oath while not in the presence of another insured.
  9. Send a signed, sworn proof of loss within 60 days of the insurer's request.

Key Procedural Conditions

ConditionTrigger / time frameExam point
Loss paymentWithin 60 days after proof of loss and agreement/court judgmentInsurer's obligation, not the insured's
Suit against insurerMust be brought within 2 years of the lossStatute-style limitation
AppraisalEither party may demand if they disagree on amount (not coverage)Each picks an appraiser; the two pick an umpire
Our optionInsurer may repair/replace with like propertyReduces moral hazard
Mortgagee (loss payable)Protects lender even if insured's act voids coverageLender gets notice of cancellation/nonrenewal
AbandonmentInsured may NOT abandon property to the insurerCommon trap

Under appraisal, disputes are limited to the amount of loss, never whether coverage exists. The two appraisers select an umpire; agreement by any two of the three sets the amount.

Conditions Applicable to Both Sections

These include the policy period (losses must occur during it), concealment or fraud (material misrepresentation voids coverage), liberalization (broadened forms apply automatically without extra premium), waiver or change of provisions (changes must be in writing), and cancellation/nonrenewal rules. The exam often pairs concealment/fraud with the duty to submit to examination under oath, and contrasts the insurer's right to cancel for nonpayment (short notice) versus other reasons (longer notice, typically 30 days).

Section II Conditions

Section II has its own conditions that mirror but differ from Section I:

  • Limit of liability - Coverage E is the most the insurer pays for all damages from one occurrence, no matter how many insureds, claims, or persons are involved. This caps stacking.
  • Severability of insurance - the policy applies separately to each insured, but this does not increase the limit. A claim by one insured against another may still be barred by the exclusion for injury to an insured.
  • Duties after loss (Section II) - the insured must give written notice of the occurrence, forward legal papers (suits, summonses) immediately, cooperate, and not voluntarily make payments or assume obligations except for first aid to others at the time of the accident.
  • Duties of an injured person (Coverage F) - the injured party must give proof of claim and authorize the insurer to obtain medical records.
  • Bankruptcy of an insured does not relieve the insurer of obligations.

Deductibles and Other-Insurance

The deductible applies to Section I property losses only - it never reduces Coverage E or F payments. A standard deductible is often $500 or $1,000; raising it lowers premium. The other-insurance condition in Section I states that if a loss is covered by other insurance, the policy pays only its pro-rata share (its limit divided by total applicable limits). For liability, Section II is generally excess over other collectible insurance only for certain situations, but typically responds on a primary basis at the residence. Understanding pro-rata sharing is a recurring numeric exam item.

Test Your Knowledge

A home has a replacement cost of $500,000. The owner insures Coverage A for $300,000. A kitchen fire causes $80,000 in damage with a $2,000 deductible. Applying the 80% coinsurance condition, how much will the insurer pay?
