What is a written condition in an insurance policy that must be fulfilled?

The correct answer is a warranty. In insurance terms, a warranty is a written condition within the policy that the insured must fulfill. This can be a specific requirement that, if not met, may lead to the nullification of the policy or a denial of a claim.

Warranties serve as a crucial part of the contractual relationship between the insurer and the insured, establishing clear expectations and obligations. For example, if a warranty states that a property must be maintained to certain standards, failure to comply can significantly affect the validity of coverage during a claim incident.

Understanding warranties is essential, as they are typically more stringent than representations or other conditions; they require absolute adherence. In contrast, other terms such as waivers refer to relinquishing a right, disclosures involve providing necessary information, and concealment relates to intentionally omitting facts. Each of these has different implications within the insurance context, but warranties specifically denote conditions that must be met for the insurance policy to remain valid, which is why they are the correct answer in this context.
