Contract law
An insurance policy is a contract. This page covers what makes it valid, its special legal characteristics, and the doctrines that decide disputes. All STABLE.
The four elements of a valid contract
Section titled “The four elements of a valid contract”Every contract (insurance included) needs:
- Offer and acceptance (agreement) — one party offers, the other accepts. (In insurance the applicant usually makes the offer via the application + premium; the insurer accepts by issuing the policy.)
- Consideration — each side gives something of value. (Insured gives premium + truthful statements; insurer gives the promise to pay covered losses.)
- Competent parties — legal capacity (of age, mentally competent, not intoxicated; the insurer must be authorized).
- Legal purpose — the contract must be for a lawful objective (and requires insurable interest).
Special characteristics of insurance contracts
Section titled “Special characteristics of insurance contracts”These five are a perennial exam favorite — remember “A CUP of Coffee… + Personal” (Adhesion, Conditional, Unilateral, aleatory (“P”… actually use the set below):
| Characteristic | Meaning |
|---|---|
| Adhesion | “Take it or leave it” — the insurer writes it, the insured can’t negotiate terms. Ambiguities are construed against the drafter (the insurer). |
| Aleatory | Exchange of unequal amounts — a small premium may yield a large claim payment (or none). Outcome depends on chance. |
| Unilateral | Only one party (the insurer) makes a legally enforceable promise. The insured isn’t obligated to pay premium, but if they don’t, there’s no coverage. |
| Conditional | Coverage depends on conditions being met (e.g., paying premium, giving notice of loss, cooperating). |
| Personal | Insurance follows the person/insurable interest, not the property; generally can’t be assigned without insurer consent (life insurance is the exception — proceeds/ownership can be assigned). |
Legal doctrines that decide disputes
Section titled “Legal doctrines that decide disputes”- Representations — statements believed true on the application. A misrepresentation is a false one; if material, it can void the policy.
- Warranty — a statement guaranteed true (a higher bar than a representation); breach can void coverage. (Most personal-lines statements are treated as representations, not warranties.)
- Concealment — silence — deliberately withholding a material fact you had a duty to disclose. Material concealment can void the policy.
- Fraud — intentional deception to gain an unfair/unlawful advantage.
- Waiver — the voluntary giving up of a known right (e.g., an insurer accepting a late premium waives the right to deny on lateness).
- Estoppel — once you’ve waived/led someone to rely, you’re stopped from asserting the right later. (Waiver and estoppel travel together and tie back to apparent authority in 02 Agency law.)
- Parol evidence rule — the written policy is the whole agreement; prior oral statements generally can’t contradict it.
Why “material” is the magic word
Section titled “Why “material” is the magic word”Across representations, concealment, and misrepresentation, the question is usually “was it material?” — i.e., would it have changed the insurer’s decision to issue or its terms? Materiality is the hinge between “harmless mistake” and “voidable policy.” This is also why the application’s background questions must be answered truthfully.
Connection to underwriting and E&O
Section titled “Connection to underwriting and E&O”- These doctrines are how an underwriter can rescind a policy obtained by misrepresentation — a core risk-management tool. See 01 Risk selection.
- And they’re why an E&O policy exists: a producer who fills out an application carelessly, or fails to disclose a material fact, can be sued. See 02 E&O / professional liability.
