1.2 Insurable Interest, Indemnity, and Insurance Principles

Key Takeaways

  • Life insurance requires insurable interest only at application; property/health requires it at the time of loss.
  • Indemnity restores the insured to their pre-loss financial position and prevents profiting from a loss.
  • Life insurance is a valued (stated-amount) contract, not a pure indemnity contract.
  • Coordination of benefits caps total payment at 100% of the actual expense across multiple health plans.
  • Application answers are representations, so only a material misrepresentation can void the policy.

Insurable Interest

Insurable interest means the policyowner must stand to suffer a genuine financial or emotional loss if the insured event occurs. Without it, a contract is a wager and is void. The exam draws a sharp line on when insurable interest must exist, and life insurance differs from property/health insurance.

  • Life insurance: insurable interest must exist only at the time of application (policy inception), not at the time of the insured's death. A wife who insures her husband's life keeps a valid claim even after they divorce, because the interest existed when the policy was bought.
  • Property and health insurance: insurable interest must exist at the time of loss.

Who has insurable interest in a life? You always have an unlimited insurable interest in your own life. You also have it in the life of a spouse, and in persons on whom you depend financially — a business partner, a key employee, or a debtor (a creditor may insure a debtor up to the loan balance). A stranger has none.

The Principle of Indemnity

Indemnity means restoring the insured to the same financial position held before the loss — no better, no worse. Its purpose is to prevent the insured from profiting from a loss, which would create moral hazard. Property and health insurance are indemnity contracts.

Life insurance is not a pure contract of indemnity. Because a human life has no fixed dollar value, life policies are valued (or stated-amount) contracts: they pay the agreed face amount regardless of "actual" economic loss. This is why a $500,000 life policy pays $500,000 even though no one can prove the deceased was "worth" exactly that.

Several mechanisms enforce indemnity in health and property lines:

  • Deductibles and coinsurance — the insured shares part of the loss.
  • Coordination of benefits (COB) — prevents collecting more than 100% of expenses across multiple health plans.
  • Subrogation — after paying, the insurer takes the insured's right to recover from a negligent third party, so the insured is not paid twice.

Coordination of Benefits: A Worked Example

When a person is covered by two group health plans, COB rules decide which pays primary (first, up to its limits) and which pays secondary (covers remaining eligible expenses, never producing a total above 100% of the bill).

Worked example. Maria has a $1,000 covered medical bill. Her own employer's plan is primary and pays 80%, or $800. Her spouse's plan, secondary, would normally pay 80% too, but COB caps total payment at the actual expense. The secondary plan pays only the remaining $200, not another $800. Maria's out-of-pocket cost is $0, and she does not profit.

The birthday rule determines primary coverage for a dependent child covered by both parents: the plan of the parent whose birthday falls earlier in the calendar year (month and day, not year of birth) is primary. If both parents share the same birthday, the plan in force longer is primary.

Additional Insurance Principles

  • Utmost good faith — both parties rely on each other's honesty. The insured must disclose material facts; the insurer must deal fairly.
  • Representations vs. warranties — a representation is a statement believed true to the best of the applicant's knowledge; a warranty is guaranteed absolutely true. Application answers are treated as representations, so only a material misrepresentation (one that affected the underwriting decision) lets an insurer void the contract.
  • Concealment — the deliberate withholding of a material fact; it too can void coverage.
  • Fraud — intentional deceit to gain an unfair advantage.
  • Stranger-originated life insurance (STOLI) — arrangements where investors with no insurable interest fund a policy on a stranger; these violate insurable-interest law and are prohibited.

Insurable Interest in Life vs. Property Insurance — Timing Trap

A heavily tested distinction is when insurable interest must exist. In life insurance, insurable interest must exist only at the inception (application) of the policy — not at the time of the insured's death. A creditor who insures a debtor's life keeps the full policy even if the debt is later repaid. In property and casualty insurance, insurable interest must exist at the time of loss. This timing split is a guaranteed exam item.

Who has insurable interest in a life? You always have unlimited interest in your own life. You have interest in another person's life if there is a close family/blood/marriage relationship or a bona fide financial/business relationship (creditor-debtor, business partners, key employee). A stranger may not buy a policy on you — that would be a wagering contract, which is void as against public policy.

Indemnity and Related Concepts

The principle of indemnity says a person is restored to approximately the same financial position after a loss, with no profit. Life insurance is technically a valued contract (it pays a stated face amount, not a measured loss) rather than a pure indemnity contract, but the underlying insurable-interest requirement still prevents profiting from a stranger's death.

Supporting doctrines: subrogation lets an insurer that paid a claim pursue a negligent third party (it prevents double recovery and applies mainly to health/property, not life). Stop-loss/coordination of benefits provisions likewise enforce indemnity in health coverage. Misrepresentation, concealment, and fraud undermine the good-faith basis of the contract: a material misrepresentation — one that would have changed the underwriting decision — can void coverage during the contestable period.
