1.2 Insurable Interest, Indemnity, and Other Insurance Principles

Insurable Interest

An insured must suffer a genuine financial loss if the covered property is damaged or the covered person is held liable. This is insurable interest, and without it a policy is an unenforceable wager.

Timing rule — memorize the difference:

• Property & casualty: insurable interest must exist at the time of loss (you can insure a car you are about to sell, but you must still own/owe on it when it is wrecked).
• Life insurance: insurable interest must exist only at policy inception (issue).

Insurable interest can arise from ownership, a secured creditor's stake (a mortgagee or lienholder), a contractual obligation (a bailee responsible for goods), or potential legal liability.

Trap: A bank lending $300,000 on a $400,000 home has insurable interest only up to its outstanding loan balance, not the full value.

The Principle of Indemnity

Indemnity restores the insured to approximately the same financial position held just before the loss — no better, no worse. P&C insurance is built on indemnity to remove any profit motive (which would create moral hazard).

Provisions that enforce indemnity

ACV worked example: A 6-year-old roof with a 20-year life costs $18,000 to replace. Depreciation = (6 ÷ 20) × $18,000 = $5,400. ACV = $18,000 − $5,400 = $12,600 (before any deductible).

Beyond Indemnity: Valued and Replacement-Cost Policies

Two exceptions go beyond strict indemnity:

• Replacement Cost (RCV): pays to repair/replace with no deduction for depreciation, subject to the insured actually rebuilding and to coinsurance compliance. Common on homeowners dwelling coverage.
• Valued policy / agreed value: the face amount is paid regardless of ACV — used for fine art, antiques, and in states with valued-policy laws for total fire losses to real property.

Subrogation, Contribution, and Other Insurance

• Subrogation — after paying its insured, the carrier steps into the insured's shoes to sue the negligent third party. The insured must not waive or impair this right after a loss.
• Contribution / Other Insurance — when two policies cover the same loss, they share it. Pro rata splits by limit; primary and excess stacks one over the other.

Pro-rata worked example: A $60,000 loss is covered by Carrier A ($100,000 limit) and Carrier B ($50,000 limit). Total limits = $150,000. A pays 100/150 × $60,000 = $40,000; B pays 50/150 × $60,000 = $20,000.

Utmost Good Faith and Its Doctrines

Insurance contracts demand utmost good faith (uberrimae fidei) — full, honest disclosure by both parties. Four supporting doctrines appear constantly:

• Representation — a statement believed true when made; a false one is a misrepresentation.
• Material misrepresentation — a false statement that, if known, would have changed the underwriting decision; grounds to rescind (void) the policy.
• Warranty — a guarantee whose breach can void coverage (rarer in personal lines).
• Concealment — silence about a material fact the applicant knew; intentional concealment voids coverage.

Trap: Innocent misrepresentation of an immaterial fact does not void coverage; only material misstatements do.

Timing of Insurable Interest

A critical exam distinction: in property insurance, insurable interest must exist at the time of loss (not necessarily at policy inception); in life insurance, it must exist only at inception. A buyer who purchases property after the policy starts can still recover if they hold interest when the loss occurs.

Supporting Principles of Indemnity

Worked subrogation example: an insurer pays its insured $30,000 for collision damage caused by a negligent third party. The insurer then pursues the at-fault driver's carrier and recovers $30,000. If it recovers only $24,000 after a $6,000 deductible was involved, many policies return the deductible to the insured first (the "make-whole" practice). Either way the insured cannot keep both the claim payment and a separate recovery from the tortfeasor - that would violate indemnity.

Stated-Value and Valued Policies

Most property policies are indemnity contracts paying actual loss up to the limit. A valued policy (common for fine arts, antiques, ocean-marine hull) pays an agreed amount regardless of actual cash value, because depreciation is hard to prove. Some states impose a valued policy law for total fire losses to real property, requiring the insurer to pay the full face amount.
