Most of a claim happens in conversation - calls with adjusters, emails about inspections, photographs sent back and forth. The proof of loss is where it stops being a conversation.
It is a formal, usually sworn statement of what was lost and what you are claiming. Once signed, it is the document your claim is measured against, and the deadline attached to it is one of the stricter ones in insurance.
What this guide covers
- It is a sworn statement, not a summary - accuracy matters legally
- The deadline usually runs from the insurer's request, not the loss
- Submit within the deadline even if figures are still estimated
- Say clearly which items are estimates and reserve the right to supplement
- Ask for extensions in writing before the deadline, never after
- Keep a complete copy of everything submitted
What it is for
A proof of loss serves the insurer's need for a definite statement of the claim: what happened, when, what was damaged, and how much is sought. Up to that point the file is a collection of impressions. Afterwards there is a number and a signature.
Most policies contain a provision requiring the insured to submit one on request, within a stated period, and treat compliance as a condition. That is why the form matters more than its plain appearance suggests.
Whether one is required in a specific claim depends on the policy and sometimes on state law. Some insurers request one routinely; some only for larger losses; some rarely. Do not assume it will not be requested.
What it asks for
Forms vary between insurers and by line of insurance, but the substance is consistent:
- The policy number and claim number.
- The date, time and cause of loss.
- A description of what happened, usually brief.
- The property involved and its location.
- The amount claimed, often split between building, contents and additional living expenses.
- Other insurance covering the same loss.
- Encumbrances such as a mortgage or lienholder.
- A declaration that the statement is true, signed and frequently notarised.
Attachments carry the weight: itemised contents lists, repair estimates, invoices, photographs and receipts.
Completing it when figures are not final
This is the practical difficulty in almost every property claim. Repairs are ongoing, estimates are outstanding, and the deadline arrives before the numbers do.
Submitting nothing is the worst option. The workable approach:
Submit within the deadline with the best supported figures available.
Label estimates as estimates. Where a figure is based on a quote rather than a completed invoice, say so on the form or in an accompanying letter.
State that you reserve the right to supplement as final costs are determined, and explain why - repairs incomplete, contractor estimates outstanding, contents inventory still being compiled.
Ask for an extension in writing where you genuinely need one, before the deadline passes, and keep the response.
Attach what you have, even if incomplete, and note what is still to come.
An accurate, clearly-qualified submission on time is in a far better position than a complete one submitted late.
Accuracy is not optional
The declaration on the form is the reason to be careful. It is typically a sworn statement, and knowingly overstating a claim can have consequences well beyond the claim being reduced, including denial and referral for investigation.
That does not mean understating. It means:
- claim what you can evidence, and evidence what you claim;
- do not include items you are unsure about without flagging the uncertainty;
- use documented values rather than optimistic recollection;
- if you do not know something, say you do not know rather than estimating silently.
The home inventory guide covers building the contents documentation that supports these figures, and the valuation guide covers why the basis your policy uses changes the numbers you should be putting on the form.
Proof of loss submission checklist
Find the deadline in the request letter and the policy
It usually runs from the request, not the date of loss.
Diarise the deadline with an advance reminder
Work backwards from it rather than towards it.
Use the insurer's own current form
Request it directly rather than using a version found online.
Gather itemised contents lists with values
Description, age, purchase price, replacement cost.
Collect repair estimates and completed invoices
Two independent estimates where the scope or cost may be contested.
Attach photographs and receipts
Cross-referenced to the items claimed.
Separate the claim by coverage
Building, contents and additional living expenses, where applicable.
Label every estimated figure clearly
And explain why it is not yet final.
State that you reserve the right to supplement
With the reason - repairs incomplete, estimates outstanding.
Disclose other insurance and any lienholder
Omissions here cause problems later.
Have it notarised if the form requires it
Build the appointment into your timeline; it is easy to leave too late.
Submit by a method that proves delivery
Tracked post or a portal confirmation you screenshot.
Keep a complete copy of the form and every attachment
Exactly as submitted, with the delivery record.
Requirements, deadlines and consequences of late submission are set by your policy and by state law, and vary considerably. Read your own policy alongside this.
Submitting it
Use a method that produces a delivery record. Tracked or certified post with a signature is the strongest; where the insurer offers a claims portal, use it and screenshot the confirmation including any reference number.
Note the delivery date, not the posting date, since compliance is generally measured from receipt.
Keep a complete copy of exactly what was submitted, attachments included. If a question arises months later about what you claimed and when, that copy is the answer.
After submission
The insurer reviews and responds, which may mean payment, a request for further information, a partial payment, or a dispute about the amount.
Keep the claim log running: every call, every document, every promise, with dates. Where the disagreement is about the amount of loss rather than coverage, many property policies contain an appraisal clause under which each side appoints an appraiser and an umpire resolves differences - a separate route from the appeal process.
Where the disagreement is about coverage, that runs through the appeal process instead. The claim denial guide covers how to structure an appeal, and the deadlines guide covers how long insurers have to respond.
When to involve a lawyer
This guide describes a form and its deadlines. It does not interpret your policy, tell you what to claim, assess whether a settlement is reasonable, or advise on the consequences of a late submission in your state.
Speak to a licensed attorney in your state if the loss is significant, if the deadline has passed or is close and you cannot comply, if the insurer alleges misrepresentation, if you are asked to sign a proof of loss with figures you are not confident in, or if the claim is already in dispute. Public adjusters are licensed in many states to prepare claims on a policyholder's behalf and can help with the documentation, though they are not lawyers and cannot advise on legal rights. Your state department of insurance can also explain what the regulator expects of insurers, at no cost.
