Definition
A Sworn Proof of Loss is a formal written statement, signed and notarized by the claimant under oath, detailing the facts of a loss, property damaged or destroyed, values, policy coverage, and the claimed amount. Most property and casualty policies require the claimant to file a Sworn Proof of Loss within a specified time frame (typically 60–90 days after the insurer requests it) or face claim denial. Because the statement is sworn and notarized, any material misrepresentation — intentional or negligent — can expose the claimant to criminal fraud charges. The Sworn Proof of Loss serves as the insurer's formal record of the claimant's account of events; it is binding on the claimant and cannot easily be contradicted later. Courts in many states have held that late filing of a Sworn Proof of Loss does not automatically void coverage unless the insurer proves actual prejudice from the delay. However, insurers routinely use late filing as grounds for denial, so meeting the deadline is critical. Public adjusters and insurance attorneys often assist policyholders in preparing Sworn Proofs of Loss to ensure accuracy and completeness, reducing the risk of technical denials or fraud exposure.
