1.2 Insurable Interest, Indemnity, and Insurance Principles
Key Takeaways
- Life insurance requires insurable interest only at inception; property insurance requires it at the time of loss.
- Indemnity restores the insured to pre-loss position; life insurance is a valued (not indemnity) contract paying a stated face amount.
- Subrogation and coordination of benefits prevent double recovery and over-payment beyond 100% of allowable expense.
- Under COB the birthday rule decides which parent's plan is primary for a dependent child.
- Utmost good faith is enforced through representations, concealment, warranties, materiality, and waiver/estoppel.
Insurable Interest
Insurable interest means a person stands to suffer a genuine financial or emotional loss if the insured event occurs. Without it, an insurance contract is an illegal wager and is void.
The critical exam rule concerns timing:
- In life insurance, insurable interest need only exist at the time the policy is issued (inception) — not at the time of death. A wife who insures her husband, then divorces him, keeps a valid policy even though the interest later disappears.
- In property insurance, insurable interest must exist at the time of loss.
A person always has unlimited insurable interest in their own life. Insurable interest in another life arises from: a close family relationship (spouse, parent, child), or a financial relationship — a creditor in a debtor, a business in a key employee, or partners in one another. A stranger has none.
When Insurable Interest Must Exist in Life vs. Property
A subtle, heavily tested timing rule distinguishes the lines. In life insurance, insurable interest must exist only at the time of application (policy inception); it need not survive to the date of death. A wife who insures her husband keeps a valid claim even after divorce, because interest existed at issue. In property and casualty insurance, by contrast, insurable interest must exist at the time of loss. Confusing these two timing rules is one of the most common fundamentals misses on the exam.
| Line | When insurable interest must exist |
|---|---|
| Life | At application (inception) |
| Property/casualty | At the time of loss |
Who Has Insurable Interest in a Life
A person automatically has insurable interest in their own life, in a spouse, and in those on whom they depend for support or money. A business has insurable interest in a key employee or business partner. Insuring a stranger's life for profit is a wagering contract that violates legal purpose and renders the policy void.
Indemnity, STOLI, and the Principle of Reimbursement
The principle of indemnity restores the insured to the pre-loss financial position and no further, preventing profit from insurance. Life insurance is technically a valued (stated-amount) contract rather than a strict indemnity contract, yet the anti-wagering purpose still bars Stranger-Originated Life Insurance (STOLI) schemes in which investors with no insurable interest finance a policy to collect the death benefit.
Worked Insurable-Interest Scenario
A bank lends a business $500,000 and insures the owner's life for $500,000 to protect the loan -- valid, because the creditor has insurable interest up to the debt. As the loan is repaid to $200,000, the creditor's insurable interest shrinks, and a policy grossly exceeding the remaining debt edges toward a wagering contract. For life insurance the interest is tested at issue, but regulators scrutinize creditor policies that vastly exceed the obligation.
Additional Exam Traps
- Life insurable interest is tested at application; property at the time of loss.
- A STOLI arrangement lacks insurable interest and is void as wagering.
- You always have unlimited insurable interest in your own life.
When must insurable interest exist for a life insurance policy to be valid?
The Principle of Indemnity
Indemnity means restoring an insured to the same financial position held before a loss — no better, no worse. It prevents the insured from profiting from insurance. Most health insurance (medical expense, reimbursement plans) is governed by indemnity: it pays actual covered expenses, not a windfall.
Life insurance is NOT a contract of indemnity — this is a heavily tested point. The value of a human life cannot be precisely measured, so life insurance is a valued contract: it pays a stated face amount regardless of any measurable economic loss. Likewise, certain health products pay on a valued basis: an Accidental Death & Dismemberment (AD&D) policy or a flat-rate hospital indemnity plan pays a set sum per day or per event, not actual cost.
Supporting Principles That Enforce Indemnity
Several doctrines exist to keep indemnity (and to prevent over-recovery):
- Subrogation — after paying a claim, the insurer takes over the insured's right to recover from a negligent third party. This stops the insured from collecting twice (once from the insurer, once from the wrongdoer).
- Coordination of Benefits (COB) — when a person is covered by two group health plans, COB rules name one plan primary and the other secondary so total payments never exceed 100% of the allowable expense.
- Coinsurance — the insured shares a percentage of covered costs (e.g., the plan pays 80%, the insured pays 20%) after the deductible.
Worked COB Example
A child is covered under both parents' group medical plans. The total allowable charge is $1,000.
| Step | Calculation | Result |
|---|---|---|
| Primary plan pays (80% of $1,000) | 0.80 × 1,000 | $800 |
| Remaining balance | 1,000 − 800 | $200 |
| Secondary plan pays remaining | up to allowable | $200 |
| Total paid | 800 + 200 | $1,000 |
The family is reimbursed exactly the allowable expense — never more than 100%. Under the birthday rule, the plan of the parent whose birthday falls earlier in the calendar year is primary.
A person is insured under two group health plans. Coordination of benefits ensures that:
Utmost Good Faith and Its Doctrines
Insurance contracts demand utmost good faith — both parties rely on the honesty of the other. Three doctrines police this duty and appear repeatedly on exams:
- Representations — statements believed true by the applicant. If a material representation is false, it is a misrepresentation, which may void the contract.
- Concealment — the deliberate withholding of a material fact. Intentional concealment lets the insurer void the policy.
- Warranty — a statement guaranteed to be true; in insurance, applicant statements are usually treated as representations, not warranties, to protect consumers.
- Materiality — a fact is material if the insurer would have made a different underwriting decision had it known the truth. Only material misstatements affect the contract.
Closely related is estoppel: when an insurer waives a right (a waiver — voluntarily giving up a known right), it is later barred (estopped) from asserting that right. Waiver and estoppel travel together on the exam.
