Warranty

Guarantee of a true statement and, if proven to be false, would make an insurance policy void (e.g., insured states he or she has or does not have a specific condition).
***
Where an insured or reassured promises that something will or will not be done during the period of cover or that a particular state of affairs exists or does not exist at the inception of cover. If the promise is untrue or is not kept then the insurer/reinsurer may disclaim all liability under the policy from the date of the breach, regardless as to whether the false declaration was material to the underwriting of the contract or causative of any loss.
***
UK: A condition that must be complied with literally. A breach precludes the insured from recovering under his policy, although the loss may not have been affected by the warranty. Insurance warranties may consist of undertakings that certain things shall be done (waste removed from premises daily) or things shall not be done (certain changes in risk factors) or a declaration whereby the insured affirms or negatives a certain state of affairs, e.g. representations in a proposal form.
***
US: (1) A guarantee of the performance of a product. Product warranties are included within the definition of the named insured’s product in general liability policies. (2) A statement of fact given to an insurer by the insured concerning the insured risk which, if untrue, will void the policy.
