First notice of loss is the formal report to the insurer that a loss has occurred. It is the event that activates the claims process, opens a file at the insurer's office, and triggers the insurer's obligation to investigate and assess the claim. Most policies require the policyholder to provide first notice as soon as practicable after becoming aware of a loss, which courts have interpreted to mean within a reasonable time under the circumstances.
The restaurant operator's first notice was submitted on Monday afternoon, approximately fifty-four hours after the loss was discovered on Saturday morning. This timeline was reasonable. The operator spent the weekend dealing with the immediate crisis: shutting off the water, protecting undamaged inventory, arranging for a plumber and an extraction company, and stabilizing the premises. The broker was called first thing Monday morning, and the notice was submitted the same day. Nobody would argue that fifty-four hours was unreasonable under these circumstances.
But the timing of first notice is only part of the story. The purpose of prompt notice is to give the insurer the opportunity to investigate the loss while the evidence is fresh. When notice is prompt and the adjuster arrives quickly, the adjuster can observe the scene, photograph the damage, inspect the cause of the failure, interview witnesses, and assess the scope of the loss based on direct observation. When notice is delayed, or when the adjuster arrives days after the cleanup has been completed, the adjuster is working from secondhand information: the extraction company's reports, the plumber's invoice, the operator's description of what things looked like before the cleanup began. Secondhand information is less reliable than direct observation, and it gives both parties less confidence in the accuracy of the assessment.
