What is a sworn written statement that must be furnished by the insured to the insurer before any loss can be paid called?

The term that refers to a sworn written statement required from the insured to the insurer before any loss can be paid is known as proof of loss. This document serves as an essential part of the claims process, detailing the nature of the loss and the circumstances surrounding it. It typically includes information such as the date of the loss, what was lost or damaged, and the value of the damages. Insurers require this documentation to verify the claim and assess the extent of the loss in determining the insurance payout.

This documentation is crucial because it provides the basis for the insurer's evaluation of the claim against the terms of the insurance policy. Without submitting this proof of loss, the insurer is not obligated to move forward with the claims process, hence why it is a prerequisite for the payment of any damages incurred by the insured.
