Definition
A Proof of Loss (POL) is a formal written statement—typically sworn and notarized—that a policyholder submits to their insurance company after a covered loss. It itemizes the date, cause, and extent of the loss; identifies all damaged property; states the policy limits and applicable coverage; lists any other insurance covering the same loss; and specifies the dollar amount the insured is claiming. Most standard homeowners policies (based on the ISO HO-3 form) and commercial property policies require the insured to file a signed POL within 60 days of the insurer's request, though this deadline varies by policy and state law—some states allow extensions or waiver if the insurer fails to properly request the form. Failing to submit a timely POL can result in claim denial, though courts in many states have ruled that late filing does not automatically void coverage unless the insurer proves actual prejudice from the delay. The POL is a legally binding document; misrepresentations on it can constitute insurance fraud and void the policy under the concealment or fraud condition found in virtually all property policies.
