Insurable Interest, Indemnity, and Other Insurance Principles

Insurable Interest, Indemnity, and Other Insurance Principles

Once vocabulary is set, the exam tests the doctrines that keep insurance from becoming a wager. Each has a precise timing rule and a precise dollar consequence.

Insurable interest

An insured must stand to suffer a genuine financial loss if the covered property is damaged. In property and casualty, insurable interest must exist at the time of loss (unlike life insurance, where it must exist only at policy inception). A buyer who sold the insured building last month has no insurable interest in it and collects nothing, even with a paid policy. Sources of insurable interest include ownership, a secured creditor’s lien (a mortgagee), a lessee’s improvements, and contractual or bailee responsibility for others’ property.

Principle of indemnity

Indemnity restores the insured to the same financial condition that existed just before the loss — no better, no worse. The insured should not profit. Several mechanisms enforce this:

• Actual cash value and policy limits cap recovery.
• Other-insurance clauses prevent double recovery.
• Subrogation prevents collecting twice (from insurer and tortfeasor).
• Salvage rights pass damaged property to the insurer once it pays.

Exceptions where the insured may recover more than strict ACV: replacement cost coverage, valued policies (agreed value paid regardless of ACV — common for fine art and on autos in valued-policy states), and stated-amount coverage.

Valuation: ACV vs. replacement cost

The most-tested numeric in this domain. Actual Cash Value (ACV) = Replacement Cost − Depreciation.

Worked ACV: A roof costs $15,000 new, has a 20-year life, and is 8 years old. Depreciation = (8/20) × $15,000 = $6,000. ACV = $15,000 − $6,000 = $9,000 (before deductible). Replacement-cost coverage would pay the full $15,000 after the insured actually replaces the roof, often holding back the depreciation until proof of completion.

Coinsurance

Property forms require the insured to carry insurance equal to a stated percentage (usually 80%) of replacement value, or share the loss. The coinsurance formula:

Recovery = (Amount carried ÷ Amount required) × Loss − deductible, capped at the policy limit.

Worked coinsurance: A building has a replacement value of $500,000 with an 80% coinsurance clause, so the insured must carry $400,000. The insured carries only $300,000 and has a $100,000 loss with a $1,000 deductible.

• Required: 0.80 × $500,000 = $400,000
• Penalty ratio: $300,000 ÷ $400,000 = 0.75
• Recovery: 0.75 × $100,000 = $75,000, minus $1,000 deductible = $74,000

Trap: coinsurance is measured against value at the time of loss, not the original purchase price, and the deductible is subtracted after applying the penalty ratio.

Other insurance, subrogation, and contribution

• Pro rata other-insurance clause: each insurer pays its share of the limit — Insurer A’s limit ÷ total limits × loss.
• Contribution by equal shares: each insurer pays equally until its limit or the loss is exhausted (common in CGL).
• Subrogation: after paying, the insurer steps into the insured’s shoes to recover from the at-fault party. The insured must not impair this right (no signing waivers after loss).
• Utmost good faith (uberrimae fidei): both parties rely on each other’s honesty; concealment or misrepresentation of a material fact can void coverage.

Subrogation, Salvage, and Collateral Source

The principle of indemnity is enforced by three supporting doctrines the exam tests in pairs. Subrogation transfers the insured's right to recover from a negligent third party to the insurer after the insurer pays the claim; the insured cannot collect from both the carrier and the wrongdoer and keep both. A signed release the insured gives the at-fault party before the loss can void the carrier's subrogation right and prejudice the claim. Salvage lets the insurer take title to damaged property it pays for as a total loss (the wrecked auto, the smoke-damaged inventory) and sell it to offset the loss.

The collateral source rule and the other-insurance provisions also protect indemnity: when two policies cover the same loss, pro-rata, excess, and primary clauses prevent the insured from collecting more than the loss.

Stated, Valued, and the Exception to Indemnity

The exam contrasts ordinary indemnity with the valued policy exception. Under a valued policy law (many states, for total fire losses to real property) the insurer pays the face amount agreed at issue without proving actual value. Ocean marine agreed-value hull and cargo policies work the same way. These are exceptions — they intentionally may pay more than strict indemnity to avoid post-loss valuation fights.

Utmost Good Faith, Representations, Warranties, and Concealment

Insurance is a contract of utmost good faith (uberrimae fidei). A representation is a statement believed true when made; a material misrepresentation lets the insurer rescind. A warranty is a promise guaranteed to be literally true; in P&C a breach of a material warranty can void coverage. Concealment is silence about a material fact the applicant knew should be disclosed — actionable when intentional and material. Distinguishing these three from one another is a recurring multiple-choice pattern, and the trigger word is usually material — immaterial misstatements do not defeat coverage.
