What is a sworn proof of loss in property insurance?
A sworn proof of loss is a notarized statement of your claim: the date and cause of loss, the amount claimed, and the documents supporting it. Carriers can demand one as a policy condition, and missing the deadline in the policy or in the demand letter can forfeit the claim outright.
| What goes in it | Date and cause of loss, amount claimed, your interest in the property, other insurance, supporting documents |
|---|---|
| Form | Sworn and notarized, on the carrier blank when one is furnished |
| South Carolina | The insurer must furnish the blank within 20 days of notice, or written proof filed in the policy's time satisfies the condition, S.C. Code 38-59-10 |
| Florida clock it starts | On written request, the insurer must affirm or deny coverage within 30 days after proof-of-loss statements are completed, Fla. Stat. 626.9541(1)(i)3.e |
| Inspection deadline | Any physical inspection must happen within 30 days of the insurer's receipt of the proof-of-loss statements, Fla. Stat. 627.70131(3) |
What a sworn proof of loss actually means
A proof of loss turns a phone call into a formal, sworn claim. It states the date and cause of the loss, what you are claiming and how much, what interest you hold in the property, and what other insurance covers it, and it is signed under oath in front of a notary. Most property policies make it a condition: the carrier may demand one, and the policy sets the number of days you have to return it.
It also starts clocks that run against the carrier. In Florida, once proof-of-loss statements are completed, Fla. Stat. 626.9541(1)(i)3.e makes it an unfair claim practice to fail to affirm or deny coverage, or to state in writing that the claim is being investigated, within 30 days of your written request. Under Fla. Stat. 627.70131 the insurer must begin its investigation within 7 days of receiving the proof-of-loss statements and complete any physical inspection within 30 days of receiving them.
South Carolina puts the first obligation on the insurer. Under S.C. Code 38-59-10, if the company does not furnish a proof of loss blank within 20 days after receiving notice of the loss, written proof of the loss filed within the time the policy allows satisfies the requirement without the company's form.
What a sworn proof of loss does to a hurricane claim
Treat the date as real. Proof-of-loss windows in the policy are short and courts enforce them. Diary the day the demand arrived and the day it is due, and send the response certified with proof of delivery.
Do not guess at the number. The amount claimed should tie to a written scope and estimate you can defend line by line, because a figure invented under oath becomes the material for an examination under oath and for any misrepresentation defense the carrier raises later.
Say so when the number is not final. Reserving the right to amend or supplement as damage is discovered is normal practice and far safer than a precise wrong number. The sample response letters carry the language.
Then use the clock it starts. Ask in writing for the carrier to affirm or deny coverage, cite Fla. Stat. 626.9541(1)(i)3.e, and put the 30-day date in the file. A letter that comes back deficient can be tested against the legality checklist.
Notice of loss
The first report of the claim to the carrier. Deadlines to give notice are set by policy and by statute and have tightened significantly in Florida since 2022, so check the version that applies to your policy period.
Examination under oath (EUO)
A recorded, sworn questioning of the policyholder by the carrier's counsel, allowed by most policies as a condition of coverage. Refusing one is generally treated as breach of a policy condition, so it is the point at which most policyholders retain counsel.
Supplemental claim
An additional demand on an already-adjusted claim when the full extent of damage is discovered during repairs. Supplemental deadlines are shorter than most policyholders expect, particularly in Florida.
Reservation of rights
A letter saying the carrier will keep investigating or handling the claim without giving up any defense it may have to coverage. It is not a denial and it is not an approval, and it extends none of your deadlines or its own.
