What Is a Sworn Proof of Loss Form?

Written and reviewed by Cory Cannon, Esq.

A sworn proof of loss is a notarized form, signed under oath, that states the amount and details of your insurance claim. It is not the same thing as filing the claim: you report the loss first, and the proof of loss is a formal document your policy can require after the claim is already open. Most Florida homeowners policies give you 60 days from the insurer’s written request to return it, but that deadline comes from your policy contract, not from a statute. Check the “Duties After Loss” section of your policy for the exact number.

Handle it carefully, for two reasons. Miss the deadline, and the insurer can argue you breached a policy condition and forfeited coverage. Guess at figures, and a later correction can be recast as material misrepresentation on a sworn document. The form also works for you: under Fla. Stat. 627.70131, the insurer must begin investigating within 7 days of receiving your proof-of-loss statement and inspect within 30 days.

Findings Summary

A sworn proof of loss is a notarized, under-oath statement of the amount and details of your loss, separate from the initial claim report.
The deadline comes from your policy, most commonly 60 days from the insurer’s written request.
Fla. Stat. 627.70131 also requires the insurer to pay or deny the claim within 60 days of notice.
Errors on a sworn form can be characterized as material misrepresentation.
Write “undetermined” where a figure is genuinely unknown. Never guess under oath.
Keep a complete copy and proof of delivery.

How Do I Fill Out a Sworn Proof of Loss?

Work from documents, not memory.

Read your policy first. Confirm the deadline and whether the insurer requires its own form.
Use documented figures. State replacement cost value (what repair or replacement costs today, with like materials) and actual cash value (replacement cost minus depreciation) from a written contractor estimate. Fla. Stat. 627.7011 controls which measure your policy pays.
Attach the estimate. Supporting documents are what make sworn numbers defensible.
Write “undetermined” where you genuinely do not know. Hidden damage is common; an honest blank is safer than a sworn guess.
Sign before a notary, keep a complete copy, and send it by a method that proves delivery.

Where Does the 60-Day Deadline Come From?

From the policy itself. Some policies require a proof of loss only after a written demand; a few require one automatically after any loss. That is separate from the one-year statutory deadline to report the claim under Fla. Stat. 627.70132, covered in our guide to Florida hurricane claim filing deadlines. Our insurance claim deadline calculator maps both dates, and the insurer response timeline checker tracks the carrier’s own countdown after you submit.

Have It Reviewed Before You Sign

We recommend attorney review of any sworn claim document before it is notarized, the same caution we give about recorded statements. Cory Cannon comes from generations in the Florida construction trades, and we check proof of loss figures against written bids from licensed local contractors before a client swears to them. If the carrier pays less than the documented loss, our underpaid claim practice reviews the file; if it denies outright, start with our denied claim page. Our Florida property insurance claim process overview and resource library explain what follows. A consultation costs nothing: send us the form before you sign it.

Frequently Asked Questions

What happens if I miss the 60-day proof of loss deadline?

Submit it as soon as possible anyway. A missed deadline lets the insurer argue you breached a post-loss condition of the policy, but under Florida case law a late proof of loss is not automatically fatal: courts often ask whether the delay actually prejudiced the insurer's investigation. The longer you wait, the stronger the carrier's argument becomes. If the insurer has already cited the missed deadline in a denial letter, have an attorney review the policy language and the timeline before you accept that answer.

Can I amend a sworn proof of loss after I submit it?

Yes. Amended and supplemental proofs of loss are common, because hidden damage and updated contractor estimates change the numbers after the first form goes in. Submit the amendment in writing, attach the documentation that supports the new figure, and explain what changed. Keep the statutory clock in mind: Fla. Stat. 627.70132 gives you 18 months from the date of loss to give notice of a supplemental claim.

Does submitting a proof of loss lock in my claim amount?

No. The form states your loss as documented on the date you sign it. It is not a cap on recovery, and you can supplement as damage is uncovered. It is sworn evidence, though. Large unexplained swings between versions invite a misrepresentation argument. That is why documented figures, attached estimates, and the word "undetermined" for anything you cannot yet support matter so much.

Is a sworn proof of loss the same as an examination under oath?

No. A proof of loss is a written, notarized form. An examination under oath (EUO) is live questioning by the insurer's lawyer, under oath, transcribed by a court reporter. Both are post-loss duties your policy can require, and carriers often demand them together. The same caution applies to both: your sworn answers must match your sworn form, so prepare with counsel before either.
