Proof of Loss: The Sworn Claim Statement Explained

Quick answer

A proof of loss is a formal, signed statement you give your insurer that describes a loss and the amount you are claiming, and some policies require it to be sworn.

Its purpose is to give the insurer the information it needs to decide how much it owes. The deadline, contents and form differ by policy and state. Flood policies from the National Flood Insurance Program have a federal rule. Nothing here promises that any claim will be approved or paid.

Quick facts

The key facts about Proof of Loss, with sources:

Purpose: A formal statement to the insurer about the loss, to help it determine the extent of its liability ³
NFIP flood policy deadline: Within 60 days after the loss, signed and sworn ¹
ISO sample homeowners form: Within 60 days after the insurer requests it; signed and sworn ²
Who may help: An NFIP adjuster may supply the form as a courtesy; you must still send it on time ¹
Typical contents: Time and cause of loss, your interest, other insurance, repair estimates, inventory of damaged belongings ¹²
Texas note: Deadlines for filing claims vary by policy; some are one year, others much sooner ⁵
What it is not: An approval or a promise of payment ²

Key takeaways

A proof of loss is your formal statement of what was lost and what you claim. Many policies require it, and some require it to be sworn.
The deadline comes from your policy and state law. A federal flood policy sets 60 days after the loss. The ISO sample homeowners form sets 60 days after the insurer asks.
A proof of loss can need repair estimates, an inventory of damaged belongings and facts such as the time and cause of the loss.
It is a request for payment, not a decision. Coverage depends on policy wording, endorsements, exclusions, the facts and state law.
Because it is sworn, accuracy matters. Keep a copy, send it by a trackable method and ask your insurer for the deadline in writing.

What a proof of loss is, in plain terms

After a loss you tell the insurer. The insurer may then ask you for a proof of loss: a written statement, on a form, in which you say what happened, what was damaged and how much you claim.

The California Department of Insurance describes it this way: a proof of loss is a formal statement made by a policy owner to an insurer regarding a loss, intended to provide the insurer with information to determine the extent of its liability ³.

On the federal flood policy it has a sharper definition. The National Flood Insurance Program’s Standard Flood Insurance Policy calls it your statement of the amount you are claiming under the policy, signed and sworn to by you ¹.

FEMA’s forms page describes the building and contents form as the policyholder’s statement of the amount of money being requested, signed and sworn to by the policyholder, and says it must be accompanied by documentation supporting the amount requested ⁴.

In short, it turns your claim from a phone call into a record. It is not the insurer’s estimate, not a contractor’s bid and not an approval. This page explains the term in general. HyreRestore does not adjust claims or prepare these forms.

General information, not legal or insurance advice

The deadline, form and contents come from your own policy and your state’s law. A sworn statement has legal weight, so read it carefully, tell the truth to the best of your knowledge and consider asking a licensed professional if you are unsure.

How the proof of loss process works

The order below combines the ISO sample form and the NFIP flood policy. Your policy’s order and time limits may differ.

You report the loss. Policies require prompt notice ².
The insurer sends a form or asks for one. The California Department of Insurance says your insurer may send you a proof of loss form to complete ³. On an NFIP policy, the adjuster may furnish the form and may help you complete it, but only as a courtesy ¹.
You gather the facts and documents. That means the time and cause of loss, who has an interest in the property, other insurance, repair estimates and an inventory of damaged belongings ²¹.
You complete and sign the statement in the way the policy requires, signed and sworn on the sample form, to the best of your knowledge and belief ².
You send it before the deadline and keep proof you sent it.
The insurer reviews it. On the NFIP policy, if the insurer rejects it in whole or part, you may accept the denial, exercise your rights under the policy, or file an amended proof of loss within 60 days of the date of the loss ¹.
The insurer decides and pays what it owes. The ISO sample form makes loss payable 60 days after the insurer receives your proof of loss and an agreement, judgment or appraisal award occurs ².

What goes in a proof of loss: the items the sample policies list

The list below is taken from the NFIP policy and the ISO sample homeowners form. Your own policy’s list may differ.
Item	What it covers	Source
Time and cause of loss	When it happened and a brief explanation of how	Both forms list it ²¹
Your interest and others’ interests	For example “owner,” plus mortgagees and anyone with a lien or claim on the property	Both forms ²¹
Other insurance	Details of any other insurance that may cover the loss	Both forms ²¹
Changes in title or occupancy	Changes during the policy term; on NFIP also who occupied the building at the time of loss	Both forms ²¹
Specifications and repair estimates	Specifications of damaged buildings and detailed repair estimates	Both forms ²¹
Inventory of damaged personal property	Quantity, description, actual cash value and amount of loss, with bills and receipts attached	Both forms ²¹
Additional living expense records	Receipts for extra living costs and records supporting fair rental value loss	ISO sample form ²
Amount claimed and justification	Your own judgment of the amount of loss, which you must justify	NFIP policy ¹

Proof of loss, estimate and inventory are three different papers

The estimate prices the repair. The inventory lists damaged belongings. The proof of loss is your sworn statement that pulls them together and states the amount claimed. See restoration scope of work for how repair scopes differ.

Example: two different deadline clocks

The example below compares the two clocks the sample forms use. The dates are invented to show how the counting differs. It does not describe any real claim, and your policy’s clock may differ.

Policy	What starts the clock	Example dates	Deadline
NFIP Standard Flood Insurance Policy	60 days after the loss ¹	Loss on March 1	60 days later is April 30, even if the adjuster has not supplied a form ¹
ISO sample homeowners form	60 days after the insurer’s request ²	Loss on March 1; the insurer requests the proof on March 20	60 days after March 20 is May 19
Policy that sets its own period	Whatever your policy says	Read the Conditions section	Ask your insurer for the date in writing
Texas homeowners policies in general	Deadlines vary by policy; some are one year, others much sooner ⁵	Check your declarations and conditions	Do not assume one year

The difference matters. On the flood policy, the clock starts at the loss and an adjuster’s help does not stop it. On the sample homeowners form it starts at the insurer’s request. Find the trigger and the number in your own policy.

Where you will meet the proof of loss

A proof of loss reaches you as a form in the mail or an online document sent by your insurer or its adjuster after you report a loss.

On flood claims the form is a FEMA form; FEMA’s page lists the Proof of Loss (Building and Contents) form as FEMA Form 206-FY-21-108 ⁴.

Your policy’s “duties after loss” or “requirements in case of loss” section is where the obligation is written ²¹.

It also appears in disaster-claim checklists. The Texas Department of Insurance, for example, lists “complete a proof of loss statement to support your claim” among the steps for flood claims ⁵. And it may be requested again if the insurer needs more information.

Our insurance claims hub and claim timeline show where it sits in the sequence.

Date everything and keep a copy

Keep a copy of the signed form and everything you attached. Send it by a method that gives you proof of delivery, and note the date. If you ask for an extension, get the answer in writing.

What a well-prepared proof of loss does for you

What it gives you

Puts your claim and amount on the record in the form your policy requires ²¹.
Meets a policy condition that, if missed, can give the insurer a reason to question or refuse the claim; the ISO sample form says there is no duty to provide coverage if failure to comply with the duties is prejudicial to the insurer ².
Forces you to organize estimates, an inventory and records in one place.
Starts or supports the insurer’s payment clock on the sample form ².

What it does not do

It is not an approval and does not guarantee payment.
A sworn statement can carry consequences if it is inaccurate, so errors matter.
It does not replace the adjuster’s own estimate, which can differ from yours.
It cannot extend a deadline or change policy wording.

Limits: what a proof of loss cannot do

A proof of loss does not decide coverage. Your insurer applies the policy, its endorsements and exclusions and the facts, as explained on sudden and accidental water damage and gradual water damage exclusion. A well-prepared statement helps you present facts, but it does not change what the policy says.

It does not fix the amount either. On the NFIP policy you must use your own judgment about the amount of loss and justify it ¹.

The insurer’s adjuster, its estimate and any appraisal can reach a different figure. The ISO sample form even provides an appraisal process if you and the insurer disagree on the amount of loss ².

The time rules are not universal. The NFIP rule is federal. Homeowners policy deadlines come from the policy and state law, and the Texas Department of Insurance says deadlines for filing claims vary by policy, with some at one year and others much sooner ⁵.

A deadline in a sample form is not your deadline.

Finally, extensions and waivers exist at times, but this page does not list any. Ask your insurer in writing whether any extension applies to your event.

What it costs, and what affects the effort

There is no fee to submit a proof of loss to your insurer. We publish no prices. What costs money or time is the evidence that goes with it: repair estimates, an inventory with receipts, and sometimes a professional who helps prepare it.

The effort rises with the size of the loss and the number of items. A claim with building damage and a large contents inventory needs more documentation than a small repair.

If you hire a public adjuster to help prepare your claim, that is a separate cost under a separate contract. See public adjuster vs. company adjuster.

For repair estimates, the cost guide and estimate checker explain how line items add up, and the contents inventory tool helps with the belongings list. There is no lifespan or warranty on the document; its practical life is the policy deadline.

How to prepare and send one

The steps below combine the sample policies and regulator guidance. Follow your own policy’s instructions first.

Find the deadline. Read your policy’s duties after loss. Ask your insurer for the date in writing.
Gather estimates. The sample forms ask for specifications of damaged buildings and detailed repair estimates ²¹. Written bids should detail materials, prices and labor line by line, per the NAIC ⁶.
Prepare the inventory. List damaged personal property by quantity, description, actual cash value and amount, and attach bills and receipts ².
State the facts to the best of your knowledge and belief: time and cause of loss, interests, other insurance ².
Justify the amount. On the NFIP policy you must use your own judgment about the amount and justify it ¹.
Review before signing. A sworn statement should be accurate. Ask a licensed professional if something is unclear.
Send and keep proof. Keep copies, note the date and keep every reply.

After you send it: keeping the claim file in order

The statement is one document in a longer file. These habits help.

Keep a log of calls and letters. The California Department of Insurance recommends this ³.
Send additional documents promptly if the insurer asks, and note when.
Report new damage found later. California says that “under most circumstances” you can reopen a claim for additional damage, and you must notify the insurer immediately ³.
File amended statements on time where the policy allows. The NFIP policy allows an amended proof within 60 days of the date of the loss ¹.
Track the payment clock your policy sets after receipt of the proof ².
Keep final invoices and completion records for any depreciation holdback. See insurance depreciation.

Warning signs and when to get help

You cannot find your deadline. Ask your insurer in writing, and ask your state department of insurance if it is unclear.
An adjuster says “do not worry about the form.” On the NFIP policy the adjuster’s help is a courtesy only, and you must still send the proof of loss on time ¹.
The insurer’s estimate is far below yours, and you are asked to sign something that adopts it. Read before signing.
Someone else offers to sign or prepare your statement for a fee and wants control of the claim. See assignment of benefits before signing anything.
Pressure to sign immediately. The California Department of Insurance warns to be wary of initial offers presented as full settlements requiring a release ³.

Do not rush paperwork over safety

Do not enter a building that has not been cleared, work around standing water and electricity, or delay emergency drying to finish a form. Protect the property and people first, document it, and use the deadline you confirmed in writing.

Where the rules come from

Your policy. The duty and the deadline live in the policy.

In the ISO sample form, Section I Conditions, “Duties After Loss” says to send, within 60 days after the insurer’s request, a signed, sworn proof of loss stating, to the best of your knowledge and belief, the time and cause of loss, interests, other insurance and related items ².

Insurers file their own forms, so your wording may differ. This is a 2000 edition sample.

Federal flood policy. The NFIP Dwelling Form, Section VII.J, says to send a proof of loss within 60 days after the loss, signed and sworn, with the information listed in J.4.

It adds that the adjuster’s help is a courtesy only and the insurer may, at its option, accept the adjuster’s report instead if you sign it ¹.

State law. States regulate claim handling and some set requirements that affect forms and time. The California Department of Insurance describes the proof of loss form and when an insurer may send it ³. We do not generalise beyond the sources we loaded; ask your state department of insurance.

Suits and time limits. The ISO sample form says no action can be brought against the insurer unless there has been full compliance with the terms of Section I and the action is started within two years after the date of loss ². State law can change that period, so check yours.

Proof of loss vs. related claim documents

Document	What it is	How it differs
Claim report or notice	Your first notice that a loss happened ²	Starts the claim; the proof of loss states the amount
Proof of loss	Signed, sworn statement of the amount claimed ¹	The formal statement
Contractor estimate	A priced list of repair work	An attachment, not the statement
Insurer’s estimate or scope of loss	The insurer’s own list of damage and measurements ³	Its view, not yours
Contents inventory	A list of damaged belongings ²	Attached to the proof of loss
Adjuster’s report	The adjuster’s report of the loss, which the NFIP insurer may accept instead of your proof of loss if you sign it ¹	Prepared by the adjuster, not by you

Decision guide What to do when a proof of loss request arrives

If The insurer sends a form with a deadline: Then Put the date in your calendar and gather estimates and the inventory
If You are on an NFIP flood policy: Then Count 60 days from the loss, whatever the adjuster says
If You have no form but a policy requires one: Then Ask the insurer in writing for the form and the deadline
If You disagree with the insurer’s estimate: Then State your amount and justify it, and attach your estimates

Common myths about the proof of loss

Myth The adjuster’s estimate replaces my proof of loss.: Reality On an NFIP policy the insurer may accept the adjuster’s report instead, at its option and if you sign it; otherwise you must send the proof within 60 days ¹.
Myth A proof of loss means the claim is approved.: Reality It states what you claim. The insurer decides under the policy ².
Myth Every policy gives 60 days.: Reality The NFIP rule is 60 days after the loss. The ISO sample is 60 days after the request. Texas notes policy deadlines vary ¹²⁵.
Myth I can leave out receipts if I explain.: Reality The sample forms ask for estimates and an inventory with bills and receipts attached ².
Myth It is only for flood claims.: Reality Homeowners policies also require one when the insurer asks, per the ISO sample form and the California Department of Insurance ²³.

The regional variable: federal flood rule and state claim rules

Two layers decide your deadline. For a flood policy through the National Flood Insurance Program the rule is federal: 60 days after the loss ¹, and FEMA publishes the form ⁴.

For homeowners policies the policy and your state decide. The Texas Department of Insurance, for example, says deadlines for filing claims vary by policy, with some one year and others much sooner ⁵, and the California Department of Insurance notes that insurers may send a proof of loss form ³.

Do not borrow another state’s deadline. Ask your state department of insurance and your insurer which deadline applies to you.

When this matters most, and your next step

A proof of loss matters most the day an insurer or adjuster mentions a form, and in the weeks before its deadline. Missing it, or sending an inaccurate one, can create problems that are hard to fix later.

Your next step is to ask your insurer in writing: do you require a proof of loss, what is the deadline and how should I send it.

Then gather your repair estimates and an inventory, and review the draft with someone you trust.

See should I file a claim if you are still deciding whether to claim, and choosing a restoration company for the repair estimate side.

Questions about Proof of Loss

What is a proof of loss?

A proof of loss is a formal statement you give your insurer about a loss and the amount you claim.

The California Department of Insurance describes it as a formal statement to the insurer meant to help it determine the extent of its liability. Some policies require it to be signed and sworn. It is not an approval of the claim.

How long do I have to file a proof of loss?

It depends on the policy. The NFIP flood policy requires one within 60 days after the loss. The ISO sample homeowners form says within 60 days after the insurer requests it. The Texas Department of Insurance says deadlines vary by policy. Ask your insurer for your date in writing.

Does it have to be notarized?

Policies say how it must be signed. The NFIP policy requires it to be signed and sworn, and the ISO sample form calls for a signed, sworn proof of loss. Whether a notary is needed depends on your policy and state. Ask your insurer what form of oath it accepts. This is general information.

What goes into a proof of loss?

The sample policies list the time and cause of loss, the interests of everyone with a stake in the property, other insurance, changes in title or occupancy, specifications of damaged buildings and detailed repair estimates, and an inventory of damaged personal property. The NFIP form also asks you to justify the amount claimed.

Can the adjuster fill it out for me?

On the NFIP flood policy the adjuster may give you the form and help you complete it, but only as a courtesy.

You must still send it within 60 days after the loss. Under other policies, ask who is responsible.

A public adjuster can help prepare a claim for a fee, but you still sign it.

What if I miss the deadline?

That can create a problem for the claim, and the result depends on your policy and state law.

The ISO sample form says there is no duty to provide coverage if failure to comply with the duties is prejudicial to the insurer.

Contact your insurer at once, ask about extensions in writing and consider asking a licensed professional.

Can I change my proof of loss after sending it?

Sometimes. On the NFIP policy, if the insurer rejects your proof of loss in whole or in part, you may file an amended proof of loss as long as it is filed within 60 days of the date of the loss.

For other policies, ask your insurer what amendment rules apply and send changes in writing.

Is a proof of loss the same as an estimate?

No. An estimate prices repairs. The proof of loss is your sworn statement of the amount you claim, and it can attach estimates and an inventory. Your insurer may also write its own estimate or scope of loss, which can differ from yours. Differences are common and are worked out in the claim.

Do I need a proof of loss for a small claim?

Only if your policy and insurer require one. The duty is stated by the policy. Check your policy and ask your insurer. A small claim may also not be worth filing; see the should I file tool.

Where do I get the form?

Your insurer or its adjuster sends it. For flood claims, FEMA lists the Proof of Loss (Building and Contents) form among its policyholder forms. Do not use a form from a contractor or a stranger. If you have not received one, ask your insurer in writing and keep the reply.
