How to Build an Incident File That Supports an Insurance Claim

Why an incident file decides your claim

An insurance policy creates the right to claim, but it does not by itself set the settlement: claims resolution almost always turns on what the policyholder can demonstrate. Claims professionals consistently reach the same conclusion — the difference between a fair payment and a disputed, reduced one usually comes down to the completeness and quality of the evidence, not the nominal breadth of the cover.

A structured incident file does several jobs at once. It confirms the fact and date of the event, helps establish the cause and circumstances, records the extent of the loss and your mitigation costs, and — if the claim is disputed — becomes the basis for the insurer's internal review or a formal complaint. Build it immediately, while details are fresh and the scene is unaltered; evidence lost in the first days usually cannot be recreated later.

Capture the scene before anything changes

Photography is the backbone of the file, but timing matters more than camera quality. After ensuring safety and alerting emergency services where needed, capture the scene before anything is moved, cleaned, repaired or affected by weather. Shoot wide overviews of each affected room or area, then move closer for details: the water line on a wall, a burst fitting, a forced door, serial numbers on electronics and stock. Add a time-stamped video walk-through and note the date, time and conditions on a written page you keep with the file.

Resist the urge to dispose of the broken item. Lockton's claims guidance and most property policies are explicit: keep the damaged property, secure the site and do not alter the scene until the insurer or loss adjuster has inspected it. If something must be removed for safety — such as a fire-damaged unit — photograph it in place first, record where it came from and store it so it can be examined later. Temporary repairs that stop further loss are expected, but permanent restoration usually waits for the inspection.

• A wide overview of each affected area plus a close-up of every individual damage
• Serial numbers on appliances, equipment and stock where visible
• Date, exact time and weather conditions at the moment of recording
• A video walk-through taken before any cleaning, repair or alteration

Prove the value of what was lost

Claim settlement ultimately prices the loss, so the file must connect each damaged item to a number. Original receipts are ideal, but when they are missing, insurers generally accept bank and credit-card statements, warranty cards, email order confirmations and photographs of items as they stood in the room. A current home or business inventory prepared before a loss is the strongest baseline, because it also protects you if pre-existing damage is later questioned.

Obtain repair and replacement estimates, including two comparable quotes when another party may be responsible, plus invoices for any temporary work. For business interruption losses, the same logic applies at company scale: budgets, forecasts, order books and several years of financial statements fix the turnover baseline you claim against. Whatever the loss, keep the damaged items until the adjuster decides, because many policies reserve the right to inspect them.

Add official records and independent confirmation

Official and independent records carry a weight that a photograph alone cannot. For theft, vandalism or suspicious loss, file a police report and record the officer, station and crime reference number, as Allianz's claims guidance notes. For fire, request the fire service's report; for storm or flood, a local authority or weather-service assessment can corroborate the date and cause. Building-management and utility fault records belong in the file, and where injuries occur, so do medical records.

Witnesses and video add an independent layer. Write down names and contacts at the scene while memories are fresh, and ask what each person saw. Preserve CCTV, dashcam and doorbell footage without editing, note the time window you request and keep the original file or a verified copy — rolling systems can overwrite footage within days. The goal is a timeline that stands on its own even if you are not present to explain it.

Organize the file and track the response

Evidence only helps if the adjuster can find it. Build a simple folder structure — photos, reports, ownership, estimates, correspondence — and name each file by date and subject, such as LivingRoom_FireDamage_2025-01-10. Keep a one-page written narrative of the sequence: what happened, when it was discovered, by whom, what was done to stop further damage and who was contacted. Update it as the claim progresses.

Track every cost connected to the event, because many policies reimburse reasonable mitigation and temporary accommodation. Record temporary repairs, debris removal, storage and additional living or operating expenses, and assign a single code to the incident so related invoices are not scattered across your accounts. Back up digital files in two places and keep originals in a secure folder; a claim can stay open, or resurface in dispute, long after the event.

Report, cooperate and prepare for a dispute

Notify your insurer as soon as practicable — many policies set specific notification windows — and note the name of the person you reported to and the date. As the Insurance Bureau of Canada points out, this record can prove the claim was reported if that is ever disputed. Cooperate with the adjuster's requests for records, photos, valuations and access to the property, and put decisions in writing where possible.

If the settlement is lower than expected or the claim is declined, re-read your policy schedule to confirm the peril is covered and that you met any conditions. You are then typically entitled to an internal review, and many policies and jurisdictions offer independent appraisal, arbitration, a regulatory complaint route or court action. Present the same incident file, because the burden is often on showing the extent and value of the loss.
