[W009]
warranty
A statement by the insured about the literal truth on which the insurance contract depends. Warranties may relate to matters existing at or before the issuance of the policy (affirmative warranties) or may be undertakings by the insured that something be done or omitted after the policy takes effect and during its continuance (promissory warranties). Many states have restricted by statute the common law rule that "any breach of warranty avoids an insurance policy"; for example, under the New York law, a breach of warranty to avoid the policy must have "materially increased the risk of loss, damage or injury within the coverage of the contract."
