Legal Concepts Applied to Insurance
This section covers the legal concepts tested in CPCU 530 and how they surface in coverage and claims decisions. The exam rewards applying doctrine to facts-who is an agent, when a defense is owed, whether wording is ambiguous-rather than reciting statutes.
Sources of law and regulation
Insurance is governed by state statutes and regulations, common-law contract and tort doctrine, and case law interpreting policy wording. Under the McCarran-Ferguson Act, states primarily regulate insurance; federal antitrust law reaches insurer conduct only in limited circumstances such as boycott, coercion, or intimidation. Statutes and regulations override conflicting policy terms, while policy language overrides general common-law defaults. Courts construe ambiguity against the drafter-contra proferentem-but only when the wording is reasonably susceptible to two meanings.
Contract, agency, and claims duties
- Formation requires offer, acceptance, consideration, capacity, and lawful purpose. An application commonly serves as the offer; a binder can create temporary coverage before the policy issues.
- A producer usually acts as the insurer's agent, so notice to the producer can bind the insurer; apparent authority can arise from the insurer's conduct.
- A material misrepresentation permits rescission when the statement is false, material, and relied upon. Representations induce the contract; warranties are promises or conditions, and modern statutes often require materiality or increased hazard before a breach avoids coverage.
- The duty to defend is broader than the duty to indemnify and is triggered by allegations potentially within coverage. A reservation of rights preserves denial grounds but still requires a defense; a conflict may entitle the insured to independent counsel.
- Waiver is intentional relinquishment of a known right; estoppel requires detrimental reliance and can bar a coverage defense.
Worked example
An insured runs a fee-based daycare in her home. A parent alleges negligent supervision after a child is injured. The homeowners policy excludes "business pursuits." The complaint does not mention payment, but the insured charges fees. The insurer compares the allegations with the policy: the claim potentially falls within the exclusion, so the insurer should defend under a reservation of rights and seek a declaratory judgment. It cannot simply deny and walk away. If a covered negligence theory remains or the exclusion is ambiguous, refusing to defend may estop the insurer from later asserting the exclusion and expose it to bad-faith liability. The duty to defend is measured by the allegations, not by facts the insurer learns later.
Traps that cost marks
- Treating the duty to defend and duty to indemnify as identical.
- Assuming breach of warranty always voids coverage, ignoring materiality or statutory limits.
- Finding estoppel without detrimental reliance.
- Confusing representations with warranties.
- Treating federal law as the primary regulator of insurance.
