For a British national living in France, a leaking roof, burst pipe or flooded room can become a legal dispute as soon as an insurer says that the damage is “wear and tear”, “poor maintenance” or outside the policy. The fact that the policyholder is British, receives income from the United Kingdom or owns a French home as a second residence does not remove the protection of French insurance law. It does, however, make evidence, written communication and timing particularly important. The relevant policy may be a multirisques habitation (MRH), meaning a comprehensive French home-insurance policy, or a narrower policy covering only the mandatory risks. A dégât des eaux means a water-damage claim: leakage, pipe rupture, overflow or water penetration that causes damage to the building or possessions.
The practical question is not simply whether water entered the property. It is whether the insured event, the damaged items, the policy wording and any exclusion have been proved in the correct order. A British owner or tenant should preserve the scene, report the claim promptly, obtain a written position from the insurer and challenge any expert conclusion that confuses the cause of the leak with the extent of the damage. French courts have repeatedly required insurers to prove the facts supporting an exclusion, while requiring the policyholder to prove the reality of the loss. The steps below are designed for a British reader dealing with a French contract, a French insurer, a French property manager or a cross-border move.
I. What does French home insurance actually cover after a water leak?
A. Is a French water-damage claim covered when the cause is unclear, gradual or linked to maintenance?
Begin with the policy, not with the label used by the claims handler. French home insurance does not operate as an unlimited promise to repair every defect in a building. The contract identifies the insured risks, the property and contents covered, the limits, the excess (the franchise, meaning the amount left for the insured to pay), the depreciation rules and the exclusions. A British policyholder should obtain the full conditions générales (general terms), the conditions particulières (individual terms), the schedule, endorsements and any assistance or legal-protection option. The online certificate alone rarely contains enough information to assess a refusal.
Article L. 113-1 of the French Insurance Code sets the starting point. The official text says: Les pertes et les dommages occasionnés par des cas fortuits ou causés par la faute de l’assuré sont à la charge de l’assureur, sauf exclusion formelle et limitée contenue dans la police
. In English, accidental losses and damage, including damage caused by the policyholder’s fault, remain the insurer’s responsibility unless the policy contains a formal and limited exclusion. That rule does not guarantee payment on every claim, but it prevents a vague reference to “maintenance” from doing all the legal work.
The distinction is practical. A sudden pipe rupture, an overflowing appliance or water entering after a sudden storm may fall within a water-damage guarantee, subject to the actual wording. The cost of replacing the defective pipe, roof membrane or appliance may be excluded even though the resulting damage to plaster, flooring or furniture is insured. Conversely, a long-running infiltration caused by a known defect may be challenged if the insurer has not identified a contractual exclusion that clearly applies to the event and the particular damage. The report should therefore separate at least four questions: what failed, when it failed, what damage followed, and which clause is said to exclude payment.
Article L. 112-4 of the French Insurance Code requires exclusions, forfeiture clauses and nullity clauses to appear in the policy in very apparent characters. Its final sentence states: Les clauses des polices édictant des nullités, des déchéances ou des exclusions ne sont valables que si elles sont mentionnées en caractères très apparents
. This is a document test. Ask the insurer to identify the exact page and wording relied on, and check whether the clause is actually presented as an exclusion rather than being hidden in a general definition or an unconnected paragraph.
The clause must also be limited. In Cour de cassation, Second Civil Chamber, 6 October 2011, no. 10-10.001, the Court approved the conclusion that l’exclusion de garantie n’était pas formelle et limitée au sens de l’article L. 113-1 du code des assurances
. The decision concerned repeated water damage and a maintenance-based argument. It does not mean that every maintenance exclusion is invalid. It means that the court must test whether the wording precisely identifies the excluded situation and whether the insurer’s factual case fits it. An insurer cannot turn an open-ended criticism of the property’s age into a complete refusal without that analysis.
The same caution applies to “lack of accidental character”. A gradual leak may raise a genuine coverage issue, but the insurer should state whether it relies on the insured risk not occurring, on an exclusion, on a pre-existing defect or on a failure to limit the loss. The legal consequences are not identical. In Cour de cassation, Second Civil Chamber, 14 October 2021, no. 20-14.094, the Court’s published analysis says that a clause depriving the insured of cover because of particular circumstances of the risk constitue une clause d’exclusion de garantie
. That qualification matters because an exclusion must satisfy the formal and limited requirements of the Insurance Code.
For a British owner who spends part of the year in France, vacancy deserves separate attention. A policy may require heating, regular inspections, a working alarm, shutter checks or a maximum unoccupied period. Those requirements should be assessed against the exact dates and the actual cause of the damage. The fact that the owner was in the United Kingdom when the claim was discovered is not itself proof of a breach. Conversely, photographs showing frozen pipes, an unanswered inspection request or an earlier warning about a leak may be used by the insurer. The useful response is a dated factual explanation supported by documents, not a general assertion that Brexit makes the insurer liable.
Brexit changes immigration and cross-border administration; it does not replace French insurance law for a French home-insurance contract covering a property in France. The UK government’s Living in France guidance tells British nationals that the French authorities apply the local rules and points readers towards French legal and administrative services. A British policyholder should therefore not assume that an English-language policy summary, a UK home policy or a UK claims practice can answer the French coverage question. The decisive documents are the French policy and the evidence about the French property.
B. Who must prove the damage, the cause and an exclusion?
The proof is divided. The policyholder normally has to establish that a covered loss occurred: water damage was present, it occurred during the relevant period and the claimed items were actually affected. The insurer must then substantiate the defence it raises, such as a maintenance exclusion, a prevention condition, a policy limit or a causal break. Article 1353 of the French Civil Code states: Celui qui réclame l’exécution d’une obligation doit la prouver
. It adds that the person claiming to be released must prove payment or the event that extinguished the obligation. This is why a refusal letter should never be left at the level of a telephone conversation.
The leading practical decision for a water-damage dispute is Cour de cassation, Second Civil Chamber, 8 January 2009, no. 08-10.874. The Court held that the lower court could conclude that the policyholders had proved the reality of the alleged loss; the official decision records that the court a pu déduire que les époux X… rapportaient la preuve qui leur incombait de la réalité du sinistre allégué
. The same decision confirms that the commonly used amicable water-damage form is evidence-management, not an automatic statutory condition of reporting. If a neighbour refuses to sign, if the claim is discovered after a return from the United Kingdom or if the insurer’s own portal fails, send a detailed written declaration and preserve proof of delivery.
Evidence should be organised as a chronology. Record when the water was first seen, who discovered it, the weather, whether the property was occupied, the point at which the flow stopped, emergency steps taken, the first call to the insurer and every inspection. Take wide photographs showing the room and close photographs showing the source, tide marks, swelling, staining, mould, damaged electrical items and any temporary protection. Keep the original files with their metadata. Make a copy in a format that can be sent from France or the United Kingdom. If a plumber attends, request an invoice and a technical note identifying the observed origin without asking the plumber to give a legal opinion on insurance cover.
For contents, add purchase invoices, bank records, photographs taken before the loss, warranties, serial numbers and replacement quotations. For a French second home, ask neighbours, the syndic (the property manager for a co-owned building) or a local caretaker for dated statements. If a leak may come from a communal pipe, obtain the co-ownership maintenance records and the identity of the insurer for the building. If the damage affects a rented property, notify the landlord and, where appropriate, the syndic. Do not accept a settlement document that says the claim is fully discharged until the scope of the payment, the outstanding building works and any rights against a responsible third party are understood.
An expert’s report is important but it is not a substitute for the contract. The insurer’s expert may identify the source and estimate the repairs, yet the policyholder can challenge the reasoning, measurements, depreciation, missing items or link between the source and the damage. Ask for the report, photographs, moisture readings, estimates and the precise policy clauses considered. If the refusal is based on a supposed pre-existing defect, ask what evidence dates that defect, what part of the damage it allegedly caused and why the covered consequences are excluded.
The burden cannot be reversed by simply calling the loss “maintenance-related”. In Cour de cassation, Second Civil Chamber, 21 April 2022, no. 20-18.890, the Court quashed a decision that treated an unidentified cause as if the insured had to disprove the insurer’s prevention theory. It held that, because the cause had not been identified, l’assureur ne démontrait pas que les dommages étaient survenus du fait de l’inobservation des mesures contractuelles de prévention
. The Court concluded that the lower court had inverted the burden of proof. For a British resident, this is a useful argument when an expert report says only that several causes are possible.
There is a further safeguard against broad exclusions. In Cour de cassation, Second Civil Chamber, 15 January 2015, no. 13-19.405, the Court rejected a maintenance clause that n’était pas formelle et limitée et ne pouvait ainsi recevoir application en raison de son imprécision
. The decision is not a promise that the insurer must accept every claim. It is a reminder to compare the clause with the actual facts: “poor maintenance” in a claims email is not enough if the policy wording does not define the excluded conduct and the insurer cannot connect it to the claimed loss.
Where the insurer relies on a limitation hidden in the way the policy lists covered pipes, the same analysis applies. Cour de cassation, Third Civil Chamber, 16 March 2022, no. 18-23.954, dealt with water damage involving buried and non-buried pipes and the difference between a real exclusion and a restriction inferred indirectly from the contract. The article’s lesson is straightforward: identify the clause, read the definitions together, and ask the insurer to explain why the clause is formal, limited and applicable to the precise damage rather than to a different risk.
A British policyholder should also separate material damage from consequential loss. Repainting, drying, replacement of a damaged floor and repair of furniture may be assessed differently from temporary accommodation, loss of use, business interruption or inconvenience. Cour de cassation, Second Civil Chamber, 13 June 2019, no. 18-19.191, records a dispute where the policy wording referred to les dommages matériels subis par les biens assurés
. The contractual wording remained central to whether a loss-of-use claim could be paid. List each head of loss separately and ask for a separate contractual answer rather than accepting a global refusal.
Finally, do not destroy the evidence while trying to reduce the damage. Emergency work to stop water, secure the roof or prevent an electrical hazard is different from permanent redecoration. Keep invoices, photographs before and after the emergency work, the contractor’s description and any confirmation from the insurer. Service Public’s official water-damage guidance explains that the leak should be stopped quickly, that urgent repairs should be documented and that permanent reinstatement should normally wait until the insurer or expert has been able to inspect the damage.
II. How can a British resident challenge a refusal and recover the right amount?
A. What should you send within five working days, and how do you contest the expert’s report?
Report the claim as soon as you know about it. Article L. 113-2 of the French Insurance Code requires the insured to notify the insurer of a loss capable of triggering cover within the contractual period, and the statutory minimum for an ordinary claim is five working days. The official text states: Ce délai ne peut être inférieur à cinq jours ouvrés
. Do not wait for a perfect technical diagnosis. Send the location, policy number, date of discovery, suspected origin, immediate safety steps, visible damage, affected third parties and a statement that the cause and final amount remain under investigation.
Use the insurer’s portal if it generates a confirmation, but also send a message that can later be proved: email with an acknowledgement, a secure customer-area message saved as a PDF, or a lettre recommandée avec avis de réception (LRAR), meaning recorded delivery with proof of receipt. A British resident who is abroad should use the address stated in the policy and copy the broker, landlord, syndic or legal-protection provider where relevant. Keep the French policy number in the subject line. Explain any delay caused by travel, a closed second home, a hospitalisation or an inaccessible portal instead of silently assuming the late notice has ended the claim.
Late notification does not automatically erase the claim. Article L. 113-11 of the French Insurance Code provides that certain forfeiture clauses for a simple delay in reporting or producing documents are null. It refers to toutes clauses frappant de déchéance l’assuré à raison de simple retard apporté par lui à la déclaration du sinistre aux autorités ou à des productions de pièces
. The insurer may still argue that delay caused an identifiable prejudice, and a policy may contain other valid requirements. The correct response is to report, explain and document the delay; it is not to claim that every time limit is irrelevant.
At the first stage, request five written answers: which guarantee is engaged, which clause is said to exclude or limit it, what facts support that clause, how the amount was calculated, and which documents are still missing. If the insurer has appointed an expert, attend the inspection if possible and give the expert a concise bundle. Put disputed facts in writing before or immediately after the visit. If the property is in a remote rural area, arrange a live video inspection only if the insurer confirms that it will preserve the evidence; do not rely on a telephone description for hidden moisture or structural damage.
French law now contains a specific information rule about a counter-assessment. Article L. 113-5-1 of the French Insurance Code, created by the law of 26 May 2026 and in force from 28 May 2026, says: Lors de la réalisation du risque, l’assureur informe l’assuré de son droit de solliciter, aux frais de ce dernier, une contre-expertise effectuée par un expert de son choix
. The phrase “aux frais de ce dernier” means that the policyholder normally pays the counter-expert, not that the insurer automatically pays it. Check whether the MRH includes an expert-fee or legal-protection benefit, including a ceiling and an excess.
The official Service Public guide on home-insurance expertise explains that an expert is not automatically required for every home claim, that an insurer-appointed expert assesses cause and damage, and that a policyholder can appoint an “expert d’assuré”, meaning an expert acting for the policyholder. It also states that the policyholder should not begin substantial repairs before the inspection, subject to emergency measures. The guide gives a practical indication that an independent home-insurance assessment can cost at least €800 and may exceed €1,000. That cost must be weighed against the amount in dispute, but it may be justified where the refusal depends on causation, a large depreciation adjustment or a structural allegation.
A counter-assessment should be genuinely useful. Give the expert the policy, the insurer’s report, the chronology, the photographs and the contractor’s documents. Ask for a point-by-point response: sudden or gradual event, source, affected surfaces, pre-existing condition, emergency mitigation, repair method, depreciation, excess, temporary accommodation and any third-party responsibility. If the first expert did not inspect a concealed area, record that limitation. If the insurer’s report contains an error about the property being vacant, the date of the leak or the pipe’s location, obtain objective proof such as travel records, electricity readings, neighbour statements or the plumber’s dated invoice.
Do not sign a full-and-final settlement merely to receive an interim amount. Ask whether the payment is an advance, a partial settlement or a final discharge. If urgent works are required, seek written confirmation of what can be done without losing the right to dispute the remaining amount. A quotation is not always proof that work was necessary, but an insurer cannot fairly assess a claim if the policyholder is prevented from preserving the damaged items or repairing a danger. Keep any replaced parts where safe and photograph them before disposal.
Coverage for a third party is another separate track. Water from a flat may damage a neighbour’s ceiling, a communal staircase or a tenant’s possessions. Notify the relevant insurers and the syndic, but do not admit legal responsibility beyond the facts. Your own property-damage cover, an occupant’s liability cover and a building’s collective policy can respond to different losses. A British owner who lives in the United Kingdom and rents the French property should also check whether the policy is written for an owner-occupier, a furnished rental, an unfurnished rental or a vacant property. A mismatch of declared use can be more important than nationality.
B. What are the formal notice, mediation and court deadlines?
If the insurer refuses or offers too little, send a reasoned complaint to the service réclamations (complaints department), not only to the call-centre agent or the claims expert. The letter should identify the claim number, the date of the loss, the parts accepted and rejected, the disputed policy clauses, the evidence enclosed and the amount sought. Ask the insurer to reconsider within a defined period and to provide the expert report, the calculation, the depreciation table, the excess and the contractual basis for any refusal. Use a calm chronology. A persuasive complaint shows that the policyholder has met the reporting duty, reduced the damage and supplied proof.
The contract remains binding. Article 1103 of the French Civil Code states: Les contrats légalement formés tiennent lieu de loi à ceux qui les ont faits
. That principle works both ways. The policyholder cannot demand a guarantee that the contract plainly excludes, but the insurer must apply the guarantee and limitations actually agreed. If the contract is ambiguous, the dispute should be framed through its definitions, exclusions, endorsements and the factual evidence rather than through a generic statement that French insurers “never cover” old properties.
When the insurer has failed to perform a contractual obligation, Article 1217 of the French Civil Code lists remedies including the right to demander réparation des conséquences de l’inexécution
, meaning to seek compensation for the consequences of non-performance. In an insurance dispute, the remedy may involve payment under the policy, the cost of justified emergency measures, a properly proved consequential loss or damages caused by a distinct contractual breach. The amount still depends on the policy, causation and evidence; Article 1217 is not an automatic penalty against an insurer.
Check the two-year limitation rule early. Article L. 114-1 of the French Insurance Code provides: Toutes actions dérivant d’un contrat d’assurance sont prescrites par deux ans à compter de l’événement qui y donne naissance
. The provision contains special rules for delayed knowledge of a loss and other situations. A complaint, mediation request or email does not automatically solve every prescription issue. A British policyholder who is approaching two years from the discovery of the damage should obtain advice on the precise event, the policy wording and any legally effective interruption or suspension before relying on informal negotiations.
Do not confuse the claim deadline with the time the insurer needs to investigate. Article L. 113-5 of the French Insurance Code says: Lors de la réalisation du risque ou à l’échéance du contrat, l’assureur doit exécuter dans le délai convenu la prestation déterminée par le contrat et ne peut être tenu au-delà
. The policy therefore matters for proposals, payment and expert stages. Ask the insurer to identify the contractual timetable and explain any extension rather than accepting an indefinite “under review” response.
If the complaint remains unsuccessful, the insurer should explain access to the Médiateur de l’assurance, the Insurance Ombudsman. Service Public’s official water-damage page describes the usual sequence: respond to the refusal or reduced offer, request reconsideration, then use the Insurance Ombudsman where the conditions are met, while preserving the option of court proceedings. Check the insurer’s current complaint procedure and mediation notice because the admissibility rules may include a prior written complaint and a waiting period. Mediation does not justify allowing the two-year limitation period to expire without assessing the litigation position.
A court claim is usually brought before the competent French civil court, the tribunal judiciaire (civil court of first instance), when the dispute concerns payment under a home-insurance contract. The court can examine the policy, the expert evidence and the causal chain. In a technically disputed case, a party may ask for a judicial expert assessment, known as an expertise judiciaire, but that step has cost and timing consequences. A British claimant living outside France should obtain the insurer’s registered address, confirm service requirements, prepare a French-language bundle or certified translations where needed, and keep a complete electronic and paper record. A solicitor or barrister in the United Kingdom is not automatically able to conduct a French civil claim; a French avocat should check jurisdiction and procedure.
For an urgent situation, an application for référé—urgent interim proceedings—may be relevant to preserve evidence, obtain a technical measure or address an immediate risk. It is not a shortcut to every disputed insurance payment. The court will consider the urgency, the seriousness of the evidence and whether the requested order can be made without finally deciding the merits. A policyholder should not threaten “emergency court” in a template letter without knowing which order is sought and which court is competent.
The cross-border file should be built for a reader who may have to act from two countries. Keep the French address of the insured property, the insurer’s claims address, the broker’s details, the UK correspondence address, the date of each trip, the bank details used for premiums, and proof of any transfer or cheque. If a document comes from a UK plumber, surveyor or insurer, attach a short English explanation and, for a formal French procedure, ask whether a French translation is required. Use exact dates rather than “last summer”. Preserve original English documents and do not translate a technical conclusion into stronger French wording than the original supports.
There is no special Brexit defence against a valid exclusion, but there is also no Brexit waiver of ordinary French contractual rights. A British resident can challenge a refusal by showing the insured event, the damage, the policy wording and the weakness in the insurer’s exclusion or causation case. The most effective file is usually narrow: one chronology, one evidence index, one comparison between the policy and the refusal, one calculation of the loss, and one precise request. That structure is more useful than a long exchange of unsupported accusations.
Conclusion
A French home-insurance refusal after water damage should be treated as a proof and contract problem, not as an unavoidable consequence of being British or living partly in the United Kingdom. Report the dégât des eaux promptly, stop the leak and preserve the scene. Then obtain the full MRH policy, ask for the exact exclusion, separate emergency repairs from permanent reinstatement, and build evidence for both the cause and the amount of damage. The policyholder proves the reality of the loss; the insurer must substantiate the exclusion or prevention condition on which it relies.
The current French rules provide concrete tools: the five-working-day minimum reporting period, the requirement that exclusions be formal, limited and conspicuous, the obligation to perform the contractual benefit within the agreed period, the information right concerning a counter-assessment and the two-year insurance limitation rule. The Cour de cassation decisions cited above show why a generic reference to poor maintenance or an unidentified cause should be tested rather than accepted. A written complaint, a carefully instructed counter-expert and timely advice can preserve a claim even when the first response is a complete refusal.
For a British owner, tenant or second-home user, the final file should be understandable to a French insurer and usable before a French court: dates, photographs, technical reports, invoices, policy clauses, expert objections and a quantified request. If the dispute involves a rented property, co-ownership, a vacant home, a third party’s damage or a cross-border address, identify those relationships separately. That is the route to deciding whether to negotiate, mediate or issue proceedings before a procedural deadline removes the practical value of an otherwise arguable claim.
