At some point after you file a contents claim, your insurer will likely hand you a form called a sworn proof of loss and ask you to sign it. It looks intimidating — there's usually a notary line and language about penalties for false statements — but it's really just your claim, put formally in writing. Here's what the form does, how your room-by-room inventory attaches to it, and the handful of mistakes worth avoiding.
A proof of loss is a formal statement, signed by you, saying what happened, what was lost or damaged, and what you're claiming. The sworn part means you're signing under oath — many insurers require notarization — so it carries more weight than the notes and phone calls that came before it. Think of it as the moment your claim stops being a conversation and becomes a document. That's not a reason to be afraid of it; it's a reason to get the details right before you sign.
The form serves both sides. For the insurer, it fixes your claim in writing — one official statement they can evaluate and pay against, and a deterrent against inflated claims, since you're swearing to its accuracy. For you, it creates a clear record of exactly what you claimed and when, which matters if anything is disputed later. It's a standard step in most contents claims, not a sign that anyone doubts you. The honest, boring approach — accurate items, good-faith values — is also the approach that tends to go smoothest.
The proof of loss form itself is usually short: names, dates, policy number, cause of loss, and a total amount claimed. The substance lives in the itemized inventory you attach to it — the room-by-room list of what was lost, with a description, approximate age, and estimated replacement value for each item. Label the attachment clearly, reference it on the form (something like "see attached contents inventory"), and make sure the total on the form matches the total on the list. A mismatched total is the kind of small error that invites slow, back-and-forth questions.
Policies commonly give you a window — often somewhere in the range of 60 to 90 days, counted from the loss or from the insurer's request — to submit the proof of loss. Check your own policy and any letters from your insurer, because the window and the start date vary. If you genuinely need more time, ask for an extension in writing before the deadline passes; adjusters grant them more often than stressed claimants expect. And a complete-enough inventory submitted on time usually serves you better than a perfect one that's late — especially because you can often add to it, as covered next.
Almost everyone keeps remembering items for weeks after a loss — that's normal, not a failure. Many policies and adjusters allow you to supplement your inventory in writing after the proof of loss is submitted, as long as the claim hasn't been finally settled. The true point of no return is typically signing a final settlement or release, not the proof of loss itself. So sign the proof of loss as accurate to the best of your knowledge, keep a copy of everything, and send additions to your adjuster in writing as you remember them. If you're unsure whether your claim allows supplements, ask your adjuster — in writing — before you assume it's too late.
Three patterns cause most of the trouble. Guessing values wildly — this is a sworn document, so estimate in good faith, note age and condition, and resist rounding everything up; inflated numbers invite scrutiny of the whole list. Leaving rooms out — closets, the garage, the attic, under-bed storage; skipped spaces quietly lowball your own claim. Signing a broad release too early — read anything called a release or final settlement carefully, and don't sign one while you're still counting. ClaimList exists for the first two: it walks you room by room with a catalog of common household items and typical replacement values, so the itemized attachment builds itself as you go. It's free to build and preview your whole list; you only pay if you want the adjuster-ready spreadsheet export.
Many insurers require it — that's what makes it "sworn" — but requirements vary by insurer and jurisdiction. Look at the form itself and your policy, and ask your adjuster in writing if it's unclear. Notary services are widely available at banks, shipping stores, and online in many places.
Send the additions to your adjuster in writing as soon as you remember them. Many claims allow supplements up until final settlement, though policies vary — so ask your adjuster how they want additions handled, and avoid signing any final release while you're still finding items.
Many people handle a straightforward contents claim themselves — the form is short, and the real work is the inventory. Some hire help when a claim is large, complex, or disputed. That's a personal decision; this guide is practical documentation help, not legal or insurance advice.
ClaimList replaces the empty spreadsheet with a room-by-room catalog of 1,300+ household items with editable typical prices. Free to build and preview everything; $12 once to export the adjuster-ready spreadsheet. Runs entirely in your browser — nothing uploaded.
