When your insurer asks for a proof of loss
After you report damage, the insurer may send a proof of loss form rather than relying only on the adjuster's inspection. You fill it in yourself. List what was damaged, what it costs to repair or replace, and the amount you're claiming, backed by receipts, photos, contractor estimates, whatever shows the number is real. You sign it under oath, which is why the details have to match what you actually find and claim elsewhere in the process. Your policy sets a deadline for sending it back, often 60 days from the insurer's request, though the exact window is on your declarations page or the letter that came with the form. Missing that deadline gives the insurer grounds to deny the claim outright, so if you need more time or help putting the figures together, ask for an extension in writing before the date passes.
A mismatched number is worth checking
If the figures on your proof of loss don't match what the adjuster offered, your policy's actual terms decide who's right. Comparing coverage now shows whether your payout gap is normal or a sign to look elsewhere.
What happens after you submit the proof of loss
Once the insurer has your signed form, it reviews the numbers against the adjuster's own estimate and the coverage limits on your policy. If everything lines up, payment usually follows within a few weeks, though the exact timeline depends on your state's prompt-payment rules and how complex the claim is. If the figures don't match, the insurer will usually come back with questions or a revised offer before paying anything, so don't expect a check to show up automatically just because you filed the form.
A denial or a lowball offer at this stage is not the end of the process. You can push back with more documentation, a second contractor estimate, or a written explanation of why your number is correct. Many policies also have an appraisal clause, which lets you and the insurer each hire an independent appraiser to settle a dollar dispute without going to court. If your policy has this, the declarations page or the claims section will say so, along with how the two appraisers resolve a disagreement between them.
Keep a copy of everything you submit, the proof of loss itself, the receipts and estimates behind it, and any letters you send asking for more time. If the claim ends up in a formal dispute or you need to involve your state's insurance department, this paper trail is what shows you filed accurately and on time. Verbal conversations with an adjuster don't carry the same weight as what's in writing and signed.
If the insurer denies the claim outright after reviewing your proof of loss, the denial letter has to state a reason, usually tied to a specific policy exclusion or a problem with the documentation. Read that reason against your actual policy language, not just what the adjuster says over the phone. Exclusions get misapplied, and a denial based on a misunderstanding of your coverage is something you can contest with your insurer directly or, if that doesn't resolve it, with help from your state's insurance regulator.
What if damage already happened and you haven't filed yet
If you're reading this before you've filed anything, the proof of loss comes later. What you do now still decides how strong that form will be. Document the damage before any repairs happen, even temporary ones. Photos and video of every room or area affected, taken before you move or discard anything, are the foundation for the numbers you'll eventually put on the form.
Most policies require you to prevent further damage. Covering a hole in the roof or shutting off water to a broken pipe is expected and usually reimbursable. Keep receipts for anything you buy to do this, tarps, plywood, a plumber's emergency visit. These become part of your claim, separate from the repair or replacement costs themselves, and the proof of loss form usually has a line for exactly this kind of expense.
Report the loss to your insurer as soon as you reasonably can. Many policies set a deadline for initial notice separate from the proof of loss deadline. Waiting too long to report can create the same kind of problem as missing the proof of loss window later. The adjuster's visit, the proof of loss request, and the eventual payout all start from that first report. The sooner it happens, the sooner the clock starts moving in your favor instead of against you.
If the damage involves a type of loss your policy treats differently, say exactly what happened rather than a general description. Water from a burst pipe is not the same as water from a flood. A flood is excluded from a standard homeowners policy and falls under separate flood coverage if you have it, while a pipe that bursts inside your house usually is not. Getting that distinction right from the first phone call affects whether the claim moves forward as a covered loss or gets flagged for exclusion before a proof of loss is ever requested.
Before you sign anything
Find the deadline in your insurer's letter and mark it now. If your numbers don't match the adjuster's offer, check your declarations page before accepting either figure.
