How to Report a Claim: A Complete Guide 2026

You come home to find water spreading across the floor, or discover that your work laptop has disappeared from a locked vehicle. Perhaps you run a shop and arrive to find the front window broken. Your first instinct is usually to call the insurer and explain everything at once. That instinct is understandable, but it's not the best first move.

In France, how to report a claim is less about completing a form than about building a defensible evidence chain. You need to secure the scene, record what happened, notify the insurer within the correct deadline, and preserve proof that can still make sense weeks later. A genuine loss can become difficult to indemnify when the policyholder sends an incomplete notice, cleans up before taking photographs, or relies on a phone conversation with no written record.

The First 48 Hours After a Loss

At 8pm, a homeowner notices a damp patch spreading across the hallway ceiling. The floor is wet, paint is peeling, and water is still entering from above. The wrong reaction is to remove damaged furniture, throw away soaked materials, and start repainting before taking photographs. The right reaction is to make the area safe, stop the source if possible, and document the condition before anything changes.

A freelancer facing theft has a different version of the same problem. The laptop, charger, external drive, and work documents may be gone, but the first priority remains evidence. Record where the theft occurred, photograph damage to the vehicle or premises, preserve purchase documents, and report the incident to the police or gendarmerie where appropriate. A shopkeeper with a broken storefront should protect the opening from further intrusion, but should photograph the broken glass, frame, locks, surrounding area, and temporary protection before repairs begin.

Protect the property without destroying the proof

French insurance guidance expects the policyholder to report the loss promptly and provide a clear description of the event and damage. The official French public-service guidance on declaring an insurance claim highlights the practical evidence chain, including the circumstances, damage details, photographs, invoices, and supporting reports.

Take these immediate actions:

• Make the scene safe: Stop water, isolate electrical risks, secure an opening, or move people away from danger.
• Record before removal: Photograph wide views, close details, identifying marks, serial numbers, and the surrounding context.
• Keep damaged items: Store them safely unless they create a health or safety hazard. Ask the insurer before disposing of anything.
• Create a timeline: Note when you discovered the loss, what you observed, and what protective action you took.
• Notify without improvising: Use a traceable channel and keep the dated confirmation.

Practical rule: Emergency protection is sensible. Unrecorded restoration is not.

The first 48 hours don't decide every claim, but they often determine whether the file looks coherent. Treat the declaration as a record that another person must understand later, without having been present. That mindset prevents the small, avoidable gaps that create delays, disputes, or reduced payment.

Understanding the French Legal Deadlines

The deadline depends on the type of loss, and the starting point matters. French public-service guidance identifies a general period of 5 working days after you become aware of the loss, 2 working days for theft or burglary, and up to 30 days after publication of the government decree for a natural disaster (official deadline guidance).

A working day is not “the next day”. You need to count according to the applicable French contractual and legal rules, taking non-working days and public holidays into account. Don't wait until the final day to send the notice. A technical problem, missing attachment, or uncertainty about the correct department can leave you arguing about timing instead of coverage.

The natural-disaster decree trap

The most common misunderstanding concerns a natural disaster. The 30-day period doesn't begin on the day the flood, drought, storm, or ground movement occurred. It starts from the publication of the interministerial recognition decree in the Journal Officiel. The MAE explanation of the claim-reporting period confirms this formal structure.

That means you should alert your insurer as soon as you know there may be damage, even if official recognition hasn't yet been published. Keep photographs, repair records, expert observations, and proof of the date you discovered the damage. Once the decree appears, record its publication date and calculate the reporting period from that date.

Claim type	Deadline	Starting point	Legal basis
Theft or burglary	2 working days	When you become aware of the theft	French insurance rules and contract
Most other losses	5 working days	When you become aware of the loss	French insurance rules and contract
Natural disaster	Up to 30 days	Publication of the recognition decree in the Journal Officiel	Natural disaster recognition process

Missing a deadline can give the insurer grounds to challenge or refuse the claim, depending on the policy and circumstances. Check your contract, send the notification early, and preserve proof of dispatch. If you're also reviewing broader vehicle cover, keep the claim procedure separate from cancellation questions such as ending car insurance under the Hamon law.

Building Your Evidence Package Before You Call

A good declaration starts with a file, not a conversation. Before contacting the insurer, assemble the material that proves what happened, what was damaged, when you discovered it, and what each item was worth. You don't need a perfectly formatted dossier before making contact, but you do need enough information to send a precise first notice.

Five categories that strengthen a file

• Photographs and video: Capture the whole room, then move closer. For water damage, show the water line, damaged surfaces, source area, and affected belongings. Include a date in your file name or keep the original file metadata.
• Ownership documents: Gather invoices, warranties, purchase confirmations, and serial numbers. An original invoice identifies the item more convincingly than a bank statement screenshot that only shows a payment.
• Policy information: Keep the contract number, policyholder identity, address of the insured property, and relevant guarantees together. The insurer needs to connect the event to the correct cover without searching through multiple messages.
• Witness and third-party details: Record names, contact details, vehicle registrations, and the role each person played. If another person or business may be responsible, say so clearly.
• Official reports: For theft and many vandalism situations, a police or gendarmerie report is central to the file. Preserve the report reference and send the document when available.

Mitigate the damage, preserve the scene

You're expected to take reasonable steps to prevent further damage. A plumber may need to stop a leak, a glazier may need to board up a shop, and a vehicle may need to be moved from danger. Ask the contractor to photograph the condition before work, keep removed materials where practical, and retain every invoice and intervention report.

Number your files in a simple folder: 01_overview, 02_closeups, 03_invoices, 04_reports, and 05_correspondence. This organisation makes the adjuster's work easier and reduces the risk of sending a photograph without context. Send copies, not irreplaceable originals, unless the insurer specifically requests otherwise.

Choosing the Right Channel to Send Your Declaration

The choice of channel determines the strength of your proof. A call provides immediate guidance but leaves no exploitable trace without written confirmation. The insurer's app often allows for quick and structured submission. Email retains a copy of the message and attachments. The registered letter remains the most defensible solution when the date of sending or receipt may be contested.

Channel	Speed	Traceability	My recommendation
Phone	Fast	Low	Request urgent guidance, then confirm in writing
Insurer app	Fast	High if the proof is saved	Good choice if the receipt is downloadable
Email	Medium	High	Send a concise declaration and keep the sent message
Registered letter	Slow	Very high	To be used if proof of sending or receipt matters
In-person appointment	Slow	High only if the exchange is documented	Request a dated receipt

My rule is simple: send quickly via the app or by email, then strengthen the written trace if the file is sensitive or contested. With a registered letter, keep the declaration, postal receipt, tracking, and exact list of attachments. A conversation in person is not enough. Request a dated stamp or an acknowledgment sent by email.

To organise a property damage file, this guide to filing property damage claims reminds you of the elements to document. Use this evidence-centered method, then apply the requirements of your French contract and your insurer's instructions.

Always ask for the claim number, the name of the manager, and confirmation of receipt. If an attachment disappears from the file, your correspondence must show precisely what you transmitted and on what date. Also separate the claim declaration from any process of cancelling home insurance.

Writing a Declaration That Holds Up

After a loss, the declaration must create a defensible chain of facts before memories blur and documents disappear. Write for the claims handler who was not present. Give that person a precise chronology, identifiable damage, and a clear record of what you did.

The essential blocks

Use this structure for an email or registered letter:

• Identity: Full name, address, telephone number, and email.
• Contract reference: Policy number, insured address, and vehicle or property reference where relevant.
• Event details: Date, approximate time, exact location, and date you discovered the loss.
• Circumstances: A chronological account of what happened and what you did immediately afterwards.
• Damage inventory: Each damaged or stolen item, identifying information, condition, and available purchase proof.
• Third parties: Names, contact details, registrations, witnesses, property managers, tradespeople, police, or emergency services involved.
• Attachments: A numbered list of photographs, invoices, reports, warranties, and estimates.
• Request: Ask for confirmation of receipt, the claim number, and instructions for the next assessment step.

Separate what you saw from what you infer. Write: “On Monday morning, I found water on the hallway floor and a damp area on the ceiling below the upstairs bathroom. I turned off the local water supply, photographed the ceiling, floor, and affected furniture, and contacted a plumber. The plumber's intervention report and photographs are attached as Annexes 1 to 4.”

Avoid: “There was a serious leak and everything is ruined.” That wording gives the claims handler no usable timeline, no precise location, and no basis for distinguishing observation from opinion.

A practical opening template

Subject: Declaration of claim, policy number [reference], loss discovered on [date]

I, the undersigned [full name], insured under policy [number], declare a loss discovered on [date] at [time] at [exact address].

The circumstances are as follows: [chronological factual description]. The damaged or stolen items are listed in the attached inventory. I've included photographs, invoices, warranties, witness details, and the police or gendarmerie report where applicable.

Please confirm receipt of this declaration, provide the claim number, and tell me whether an inspection or additional documents are required.

Label photographs consistently, for example “Annex 1, hallway overview” and “Annex 2, damaged ceiling close-up”. Sign the letter sent by post, and save the complete email as a PDF.

A clear declaration gives the insurer what it needs to open and process the file. A vague one creates delays and forces you to reconstruct events under pressure.

What Happens After You Submit Your Claim

Once the notice is sent, don't stop managing the file. Save the confirmation, record every call, and answer requests in writing whenever possible. Your objective is to keep the evidence chain intact while the insurer checks coverage, causation, and the amount of damage.

Prepare for questions, not just an inspection

The insurer may request clarifications, photographs, invoices, estimates, or an official report. An adjuster or expert may examine the property, vehicle, equipment, or circumstances. Don't repair, replace, or discard significant evidence without checking whether the insurer wants an inspection first, except where safety requires immediate action.

Before an inspection, prepare:

• A room-by-room or item-by-item inventory
• A chronological account of discovery and protective measures
• Original invoices, warranties, and repair estimates
• A list of inaccessible or hidden damage
• Questions about exclusions, excess, depreciation, and the proposed method of valuation

At the visit, stay precise. Point out every affected area, including damage that isn't obvious in a wide photograph. If the expert makes a statement you dispute, don't argue emotionally. Ask for the observation to be recorded, then send a written clarification with supporting documents.

For property losses, especially roofs and weather-related damage, unfamiliar terms can make the assessment difficult to follow. A general resource on a roof damage insurance adjuster can help you understand the type of questions an adjuster may ask, although your French policy and expert report remain controlling.

Review the offer line by line

An indemnity offer should be checked against your inventory and policy wording. Look for omitted items, incorrect quantities, depreciation applied without explanation, excluded categories, and repair costs that don't match the contractor's estimate. Replacement value and depreciated value aren't interchangeable, so ask the insurer to identify the valuation basis for each line.

If the offer is too low, respond with a structured counter-file. Identify the disputed line, explain why it's wrong, attach the relevant invoice or estimate, and request a revised assessment. Keep the tone professional and the record complete. If direct negotiation fails, use the insurer's formal complaints process and then consider the Médiateur de l'Assurance according to the applicable procedure.

Specific Considerations for Business Owners and Freelancers

A business claim has more moving parts than a household claim. The same event can affect premises, equipment, stock, customer commitments, employees, revenue, and liability. A shopkeeper who reports only the broken window may later struggle to connect the closure, lost sales, emergency security costs, and damaged stock to the original event.

Separate each loss category

Declare the physical damage first, then identify the operational consequences. A business interruption claim, or business loss, needs a clear record of the interruption, cancelled orders, blocked access, replacement arrangements, and documents showing the commercial impact. An e-commerce operator should keep a separate incident log covering platform outages, payment failures, fulfilment interruptions, customer complaints, and remedial costs.

Professional liability requires a different discipline. If a client sends a formal complaint, demand, or lawyer's letter, notify the insurer promptly and preserve the entire exchange. Don't admit liability casually, promise payment, or delete messages while the insurer reviews the matter. Guidance on professional civil liability insurance can help you identify the cover that may respond, but the contract's notification clause controls the file.

Watch the freelancer and fleet traps

A freelancer's stolen laptop may involve personal contents cover, business equipment cover, cyber protection, or several policies with coordination rules. Declare the event to every potentially relevant insurer, explain the professional use, and avoid claiming the same loss twice. Keep the purchase invoice, serial number, police report, account-security records, and evidence of business interruption together.

For a fleet policy, list the vehicle, driver, location, damage, and third-party details precisely. Don't assume that notifying an employee or leasing company automatically notifies the insurer. Confirm who submitted the declaration and obtain the claim number.

Use this one-page action checklist:

1. Secure the site: Prevent further damage and record emergency measures.
2. Freeze the evidence: Photograph, film, preserve files, and save logs.
3. Identify every policy: Personal, professional, fleet, cyber, property, and liability cover.
4. Send the notice: Use a traceable channel within the applicable deadline.
5. Build the inventory: Separate physical damage, lost income, liability, and extra expenses.
6. Track the file: Keep the claim number, adviser name, dates, requests, and responses.
7. Challenge gaps: Ask for written reasons when an item or cost is excluded.

For businesses, a well-organised claim file protects more than a single payment. It preserves the evidence needed to keep trading, defend a liability allegation, and show exactly how the loss affected operations.
