Which of the following is required at the time of an insured's loss?

The requirement of notice of loss and proof of loss at the time of an insured's loss is fundamental in the insurance process. When an insured event occurs, the policyholder must promptly notify the insurer about the loss so that the insurer can initiate the claims process. This notification allows the insurer to evaluate the situation, assess the damage, and understand the circumstances surrounding the incident.

Additionally, proof of loss serves as a formal statement of the claim, providing detailed information about what happened, the nature of the loss, and often includes documentation of the value of the loss. This is crucial for the insurer to determine the validity of the claim and the appropriate compensation based on the policy coverage. Without it, the claim may be delayed or denied, as the insurer relies on this information to proceed with the claim investigation and settlement.
