4.5 Policy Structure, Policy Conditions & Insurer and Third-Party Provisions

Key Takeaways

  • Standard property and casualty policies follow the D-I-C-E-E structural framework: Declarations, Insuring Agreement, Conditions, Exclusions, and Endorsements.
  • Under standard property policy conditions, the insured must provide prompt notice of loss, protect property from further harm, prepare an itemized inventory, and submit a sworn proof of loss within 60 days of the insurer's request.
  • The Standard Mortgage Clause establishes an independent contract between the insurer and lender, ensuring the mortgagee's coverage remains fully intact even if the insured intentionally commits arson or fraud.
  • Louisiana property and casualty policies subject to R.S. 22:887 require at least 60 days’ written notice of cancellation, except 10 days for nonpayment of premium, and 60 days’ notice of nonrenewal stating the cause; auto and commercial policies follow R.S. 22:1266 and 22:1267.
  • Other insurance clauses share a loss by pro rata liability (each limit divided by total limits), contribution by equal shares, or primary and excess positions.

Core Focus: Every property and casualty policy is constructed upon a standardized five-part architectural framework known as D-I-C-E-E. Claims adjusters must navigate these sections effortlessly to verify coverage, enforce post-loss duties, handle mortgagee rights, and calculate multi-carrier pro rata liability apportionments under standard ISO policy language.


The Five Standard Policy Parts: D-I-C-E-E

Whether examining a personal homeowners policy, an auto policy, or a complex commercial package, virtually all standard insurance contracts follow the five-part D-I-C-E-E structure:

D - Declarations       (The "Who, What, Where, When, and How Much")
I - Insuring Agreement (The broad contractual promise of coverage and perils)
C - Conditions         (The ground rules, rights, duties, and obligations)
E - Exclusions         (What is explicitly NOT covered)
E - Endorsements       (Written modifications, riders, and amendments)

1. Declarations (The "Dec Page")

The Declarations page is the personalized first page of the policy contract. It contains the specific factual data that tailors a generic policy form to a particular insured and risk:

  • Identity: Named insured(s) and their legal mailing address.
  • Policy Period: Inception and expiration dates and times (standard industry practice is 12:01 AM Standard Time at the location of the insured premises).
  • Property Location & Description: Physical street address and structural details (e.g., masonry veneer, frame, roof type, occupancy).
  • Coverage Limits: Maximum dollar amounts the insurer will pay for each coverage section (e.g., Coverage A Dwelling: $350,000; Coverage C Personal Property: $175,000; Coverage E Liability: $300,000).
  • Deductibles: The applicable flat or percentage deductibles for all perils, including separate hurricane or named storm deductibles.
  • Premium Details: Total policy premium and schedule of billing.
  • Loss Payees & Mortgagees: Names and addresses of lienholders or mortgage lenders holding a financial interest in the covered property.
  • Schedule of Forms: A list identifying all form numbers and endorsements attached to the policy.

2. Insuring Agreement

The Insuring Agreement is the engine of the policy. It contains the insurer's fundamental, broad contractual promise to pay covered claims, indemnify the insured, or provide a legal defense.

  • Scope of Coverage: Defines whether the contract is a Named Perils policy or an Open Perils (Special Form) policy:
    • Named Perils: Only losses caused by perils explicitly listed in the policy (e.g., fire, lightning, windstorm, explosion) are covered. The burden of proof rests on the insured to prove a listed peril caused the damage.
    • Open Perils (All-Risk / Special Form): All causes of direct physical loss are covered except those specifically excluded. The burden of proof rests on the insurer to demonstrate that an exclusion applies.
  • Liability Defense: In casualty sections, the insuring agreement states the insurer's duty to defend any suit seeking covered damages, specifying that the duty to defend is broader than the duty to indemnify and that defense costs are paid outside policy limits.

D-I-C-E-E Policy Framework and Post-Loss Conditions

3. Conditions

The Conditions section establishes the contractual ground rules, rights, duties, and procedural obligations governing both the insurer and the insured throughout the life of the policy.

If the insured fails to satisfy these conditions, the insurer may be relieved of its obligation to pay. Key conditions include post-loss duties, cancellation and nonrenewal rules, appraisal, subrogation, and assignment.

4. Exclusions

The Exclusions section enumerates specific perils, hazards, property types, or loss circumstances that are carved out and removed from coverage.

  • Purposes of Exclusions:
    1. Eliminate uninsurable catastrophic hazards that threaten insurer solvency (e.g., war, nuclear hazard).
    2. Eliminate catastrophic perils managed by specialized federal or state programs (e.g., flood under the National Flood Insurance Program).
    3. Exclude predictable, unfortuitous maintenance events (e.g., wear and tear, rust, rot, mechanical breakdown, insect/vermin infestation).
    4. Prevent moral hazard by excluding intentional losses caused by the insured.

5. Endorsements (Riders)

An Endorsement is a written form attached to the policy that modifies, amends, expands, or deletes provisions of the original printed contract.

  • Precedence Rule: In the event of a direct conflict between the language in the base policy and an attached endorsement, the endorsement strictly takes precedence. Endorsements allow policies to be customized with special protections (e.g., water backup, scheduled personal property) or to comply with Louisiana statutory requirements (e.g., standard Louisiana amendatory endorsements).

Standard Policy Provisions & Key Clauses

Insured's Duties After a Loss

When a property loss occurs, the policy conditions impose strict, mandatory affirmative duties upon the insured. The claims adjuster must verify compliance with each of the following:

  1. Give Prompt Notice: Notify the insurer or its agent promptly of the loss, providing details of how, when, and where the loss occurred.
  2. Protect the Property (Mitigation): Take all reasonable and necessary steps to protect the property from further damage (e.g., tarping a damaged roof, boarding up broken windows, shutting off the main water valve). The policy covers reasonable emergency mitigation expenses incurred by the insured.
  3. Separate Damaged and Undamaged Property: Keep damaged items in good order to permit a thorough claims inspection.
  4. Provide a Detailed Inventory: Prepare an itemized list of damaged personal property showing quantity, description, actual cash value, age, and replacement cost, supported by purchase bills, receipts, and related records.
  5. Exhibit Property & Cooperate: Show the damaged property to the adjuster as often as reasonably required and cooperate fully throughout the investigation.
  6. Submit a Sworn Proof of Loss: Complete, sign, and swear to a formal Proof of Loss statement within 60 days after the insurer's request (or within the statutory timeframe). The proof of loss establishes the time and cause of loss, the interest of the insured and all others, all encumbrances, other insurance, and the actual cash value and repair scope.

Cancellation and Nonrenewal Under Louisiana Law

  • Cancellation: The insurer's termination of a policy before its expiration date. Under R.S. 22:887, written notice of cancellation must be delivered or mailed to the insured not less than 60 days before the effective date, except when cancellation is for nonpayment of premium, which requires at least 10 days' notice. The 60-day period took effect July 1, 2026; the earlier rule was 30 days. Like notice goes to each mortgagee or other person the policy shows as having an interest in any loss.
  • Nonrenewal: An insurer that will not renew a property or casualty policy subject to R.S. 22:887(G) must mail or deliver notice of its intention not to renew at least 60 days before the nonrenewal date and must state the cause, with like notice to mortgagees and other interested parties.
  • Other Louisiana notice statutes: Personal auto policies follow R.S. 22:1266 and commercial policies follow R.S. 22:1267, which R.S. 22:887(G) excludes. Check which statute governs the policy in the claim file before relying on a cancellation.

The Liberalization Clause

The Liberalization Clause protects the policyholder against obsolescence when policy forms are updated:

  • How It Works: If an insurer adopts a revision that broadens or expands coverage under the current edition of its policy form without charging an additional premium, that broadened coverage automatically and immediately applies to all existing in-force policies of that same form.
  • Window of Application: Under standard ISO forms, the liberalization clause applies to revisions adopted during the policy period or within 45 to 60 days prior to the effective inception date of the policy.

Mortgageholder / Loss Payee Rights (The Standard Mortgage Clause)

Under property insurance covering mortgaged real estate, the Standard Mortgage Clause (often called the Union or New York Standard Mortgage Clause) creates an independent contract between the insurance company and the mortgage lender (mortgagee):

  • Immunity from Insured's Wrongdoing: The mortgagee's right to receive insurance proceeds is not invalidated or defeated by any act, neglect, breach of condition, or intentional fraud (such as arson) committed by the mortgagor (insured homeowner). Even if the homeowner burns down their own house and is denied coverage for arson, the insurer must still pay the mortgage bank up to the bank's insurable interest (the outstanding mortgage balance).
  • Lender's Obligations: If the insured fails to do so, the mortgagee must:
    1. Pay any overdue premiums upon demand;
    2. Submit a sworn proof of loss within 60 days of receiving notice from the insurer; and
    3. Notify the insurer of any known substantial increase in hazard or change in occupancy/ownership.
  • Subrogation Rights Against the Insured: If the insurer pays the mortgagee for a loss caused by the insured's intentional arson, the insurer is subrogated to all the mortgage rights of the lender and can foreclose upon or sue the insured homeowner to recover the money paid.

Other Insurance Clauses & Pro Rata Liability

When two or more insurance policies cover the same property or liability exposure for the same insurable interest, Other Insurance clauses prevent double recovery and uphold the principle of indemnity.

Pro Rata Liability Formula

Most property policies contain a Pro Rata Liability condition stating that the insurer will pay only that proportion of the loss that its limit of liability bears to the total limit of all valid and collectible insurance covering the property:

Insurer's Share = (Insurer's Policy Limit / Total Limits of All Applicable Policies) × Covered Loss

Step-by-Step Calculation:

  • Insurer A Limit: $300,000

  • Insurer B Limit: $100,000

  • Total Combined Limits: $400,000

  • Covered Fire Loss: $80,000

  • Insurer A Share: ($300,000 / $400,000) = 75%
    Insurer A Payout: 0.75 × $80,000 = $60,000

  • Insurer B Share: ($100,000 / $400,000) = 25%
    Insurer B Payout: 0.25 × $80,000 = $20,000

  • Total Indemnification: $60,000 + $20,000 = $80,000 (exactly 100% of the covered loss, fully making the insured whole without financial windfall).

Other Named Insured, Insurer & Third-Party Provisions

PSI's outline groups several more policy provisions by whose rights they describe.

Named Insured Provisions

  • Insureds: the named insured on the declarations, often a resident spouse, and other persons the policy defines as insureds, such as resident relatives, employees using covered property, or anyone using a covered auto with permission.
  • First named insured: in commercial forms, the first name shown on the declarations receives cancellation notices and premium refunds and is responsible for paying premiums.
  • Policy period and territory: coverage applies only to losses or occurrences during the policy period and within the coverage territory stated in the policy.
  • Assignment: the insured may not transfer the policy to someone else without the insurer's written consent. After a loss, the right to collect the claim payment can generally be assigned, because the risk the insurer accepted has already occurred.

Limits of Liability

Limit typeHow it works
Per personMost paid for bodily injury to any one person in an accident
Per accident or per occurrenceMost paid for all claims from one accident or occurrence
AggregateMost paid for all claims during the policy period, such as a CGL general aggregate
Split limitsSeparate limits, such as 100/300/50 for bodily injury per person, bodily injury per accident and property damage
Combined single limitOne limit for bodily injury and property damage combined in each accident

Insurer Provisions

  • Settlement options: property policies let the insurer pay cash, repair, rebuild or replace property with like kind and quality, or take damaged property at an agreed or appraised value.
  • Duty to defend: liability policies obligate the insurer to defend suits seeking covered damages. The duty to defend is broader than the duty to indemnify and usually ends when the applicable limit is used up paying judgments or settlements.
  • Transfer of rights of recovery (subrogation): after paying a claim, the insurer takes over the insured's rights against a responsible third party, and the insured must not impair those rights after a loss.

Third-Party Provisions

  • Mortgage clause: see the Standard Mortgage Clause above.
  • Loss payable clause: used for personal property such as autos, boats and equipment. Under a basic loss payable clause, the loss payee, such as a lender or lessor, is named on the claim check but has no greater rights than the insured.
  • No benefit to bailee: a person or business holding covered property for a fee, such as a warehouse, carrier or repair shop, cannot claim the benefit of the owner's insurance. The condition preserves the insurer's subrogation rights against a negligent bailee.

Other Insurance Methods

MethodHow the loss is shared
Pro rata liabilityEach policy pays the share its limit bears to the total limits of all applicable insurance
Contribution by equal sharesEach insurer pays equal amounts until its limit is exhausted; the remaining insurers keep paying equally until the loss is paid
Primary and excessThe primary policy pays first up to its limit; the excess policy pays only what remains

Nonconcurrency exists when policies covering the same property have different terms, such as different perils or property descriptions, which complicates apportionment.
