What Goes Into a Proof of Loss

A proof of loss isn't a casual claim description. Insurers expect a specific, documented package that typically includes:

• The date, time, and cause of the loss
• An itemized list of damaged, destroyed, or stolen property with individual values
• Details of any other insurance policies covering the same property
• Any interests other parties, such as a lender or landlord, have in the damaged property
• A signed statement, sometimes notarized, affirming the information is true and accurate

Submission Deadlines and Insurer Requests

Most commercial property policies give the insurer the right to demand a proof of loss in writing after a claim is filed, and the policyholder is then required to submit it within a set window, commonly 60 days. Missing that deadline, or submitting an incomplete one, doesn't automatically kill a claim, but it gives the insurer grounds to slow down payment while they sort out the gap.

Why Accuracy Here Matters

An inflated or sloppy proof of loss invites scrutiny and delay, while an incomplete one can get bounced back and restart the clock on payment. Businesses that keep current inventory records, equipment lists, and receipts before a loss ever happens are able to complete this document in days instead of weeks, which is often the difference between a claim that pays quickly and one that drags into a dispute.
