You had finally found the house in France: the stone walls, the garden, the light. Then came the renovation. The builder, the entrepreneur<\/i>, quoted in spring, started in summer, sent two invoices, cashed the deposit, and then the van stopped coming. The scaffolding stands empty, the bathroom is a concrete shell, rain gets in through the half-fitted roof window, and your emails go unanswered. Or the builder did finish, but the floor slopes, the heating never worked properly, cracks are spreading across the new extension, and he tells you this is normal settling. If you are a British owner living in France or managing a French house from the United Kingdom after Brexit, this moment feels especially lonely: the contract is in French, the procedure is unfamiliar, and you are paying a mortgage on a building site.<\/p>\n
French law is firmly on your side in this situation, and your nationality changes nothing. Whether the builder has walked off mid-project or left behind defective work, the Civil Code gives the client, known as the ma\u00eetre de l’ouvrage<\/i>, meaning the person who commissions the works, a complete toolbox: ways to prove what happened, three legal guarantees that run once the works are accepted, a fast-track judge who can order payment or the completion of the works within weeks, and a full trial route that can end the contract, pay for a replacement builder and award damages. Even the fact that you paid the invoices in full and moved into the house can work in your favour, as a leading court decision explained. This guide walks you through each step in plain English, with the exact legal texts and court rulings a French judge would apply, so that you can force the builder to finish, to repair, or to pay, and challenge any refusal along the way.<\/p>\nI. Your builder has stopped coming or left defects: what French law calls it and which guarantees protect you<\/h2>\n
Before demanding anything, you need to put the right legal label on your situation, because the label decides which weapon you use. French law draws a sharp line between two moments: works that have never been accepted, where the builder simply fails to perform the contract, and works that have been accepted, where defects trigger a set of automatic guarantees. Many British owners lose time because they mix the two. The sections below put them in order, starting with the evidence you must gather today, whatever your situation, since proof decides everything in a French court.<\/p>\n
Your contract with the builder is almost certainly what French law calls a contrat de louage d’ouvrage<\/i>, meaning a contract for work, sometimes also called a contrat d’entreprise<\/i>. The Civil Code defines it simply: “Lorsqu’on charge quelqu’un de faire un ouvrage, on peut convenir qu’il fournira seulement son travail ou son industrie, ou bien qu’il fournira aussi la mati\u00e8re.”<\/a> In plain terms, when you engage someone to carry out building works, you may agree that he supplies only his labour or that he supplies the materials as well. An accepted written quote, a devis<\/i>, signed by both sides, counts as such a contract, and so does an exchange of emails that fixes the price, the scope and the timetable. Gather every piece of paper now: the signed quote and any general conditions attached to it, the invoices and proof of each payment, the timetable or planning emails, photographs of the site with dates, text messages in which the builder promises to return, and the names of neighbours or friends who saw the site abandoned. French courts give real weight to witness statements, called attestations de t\u00e9moins<\/i>, written in a fixed legal form, so ask witnesses to write theirs promptly while memories are fresh.<\/p>\n Next, send the builder a formal notice, called a mise en demeure<\/i>. This is not an ordinary chasing email. It is a registered letter with acknowledgement of receipt, a lettre recommand\u00e9e avec accus\u00e9 de r\u00e9ception<\/i>, which lists precisely what is unfinished or defective, sets a firm final deadline to return or to repair, typically eight to fifteen days depending on the urgency, and warns that you will go to court and hire another firm at his expense if he fails. This letter matters for three reasons. First, it proves the builder knew exactly what you reproached him with. Second, it is the legal trigger for several remedies, including hiring a replacement builder at his cost. Third, it fixes the starting point for damages for delay. Keep the postal receipt and the acknowledgement card, and from that moment onwards communicate only in writing. If the builder answers with excuses, keep his replies: admissions that the works are unfinished are precious evidence.<\/p>\n For defects, organise proof of a different kind. Draw up a dated snag list with photographs, keep samples of faulty materials, and have an independent building professional visit the property and write a detailed report with measurements and costed repair proposals. For an abandoned site, the strongest single document is a bailiff’s report, called a constat de commissaire de justice<\/i>, since the officer formerly known as the huissier de justice<\/i> now bears the title of commissaire de justice<\/i>. This sworn officer comes to the property, records exactly what is finished and what is missing, photographs everything and dates his findings. His report is extremely difficult for the builder to dispute, and judges rely on it constantly. If water is getting in or the structure looks unsafe, ask the bailiff to come within days, because you may later need urgent court orders and the judge will want to see the danger documented. Obtain two comparative quotes, called devis comparatifs<\/i>, from other builders for finishing or repairing the works: they prove both the scale of the failure and the amount you are entitled to claim.<\/p>\n Two practical points for British owners deserve emphasis. First, language: if the contract and the quotes are in French, do not sign any new document, settlement or protocole d’accord<\/i>, meaning a settlement agreement, without a full English translation you understand, and bring a French-speaking friend or interpreter to every expert visit. Second, insurance: ask the builder in writing for his ten-year liability insurance certificate, called the attestation d’assurance de responsabilit\u00e9 d\u00e9cennale<\/i>, and for the reference of your own project insurance if any was taken out. Builders sometimes vanish precisely because they are uninsured, and you need to know this early, since it changes where the money will come from. If the builder refuses to answer, that silence itself becomes part of your file, and the court will draw its own conclusions.<\/p>\n French construction law organises the builder’s liability around one central event: the acceptance of the works, called the r\u00e9ception<\/i>. The Civil Code states that “La r\u00e9ception est l’acte par lequel le ma\u00eetre de l’ouvrage d\u00e9clare accepter l’ouvrage avec ou sans r\u00e9serves.”<\/a> In other words, acceptance is the formal act by which you, the client, declare that you take delivery of the works, either cleanly or with a list of defects, called r\u00e9serves<\/i>, which works exactly like an English snag list. The same article adds that acceptance “est, en tout \u00e9tat de cause, prononc\u00e9e contradictoirement”<\/a>, meaning it must always involve both sides, so the builder is invited and can respond to your snag list. Acceptance can be written down in a signed acceptance report, called a proc\u00e8s-verbal de r\u00e9ception<\/i>, which is the ideal outcome. But French courts also recognise implied acceptance, called r\u00e9ception tacite<\/i>, and acceptance ordered by a judge, called r\u00e9ception judiciaire<\/i>, when the builder refuses to attend. This matters enormously if you paid and moved in: in a leading ruling of 12 November 2020, appeal number 19-18.213, the Third Civil Chamber of the Court of Cassation, the Cour de cassation<\/i>, France’s highest civil court, approved judges who had held that “la r\u00e9ception tacite r\u00e9sultait de la prise de possession jointe au paiement int\u00e9gral, de sorte que la date \u00e0 retenir pour le point de d\u00e9part de l’action en garantie d\u00e9cennale \u00e9tait le 26 mai 2006”<\/a>, meaning that implied acceptance resulted from taking possession together with full payment, so that the ten-year guarantee period ran from that date. Taking the keys and paying the final invoice can therefore start your guarantee periods even without a signed report, which is good news, although you should always prefer a written report with a detailed snag list when you can get one.<\/p>\n Once acceptance has happened, three guarantees protect you. The official public guidance service describes the same structure: three guarantees, namely the one-year perfect-completion cover, the two-year proper-functioning cover and the ten-year cover, whose common starting point is the date of acceptance of the works (official guidance on guarantees after acceptance<\/a>). The first is the one-year perfect-completion guarantee, the garantie de parfait ach\u00e8vement<\/i>, which obliges the builder to repair every defect you noted in your snag list or that appears during the year after acceptance, whatever its seriousness: a badly hung door, peeling paint, a leaking tap. The second is the two-year guarantee for equipment, the garantie de bon fonctionnement<\/i>: the Code provides that “Les autres \u00e9l\u00e9ments d’\u00e9quipement de l’ouvrage font l’objet d’une garantie de bon fonctionnement d’une dur\u00e9e minimale de deux ans \u00e0 compter de sa r\u00e9ception.”<\/a> Fitted equipment such as boilers, shutters, taps and electrical fittings must work properly for at least two years from acceptance. The third and most powerful is the ten-year guarantee, the garantie d\u00e9cennale<\/i>: the Code states that “Tout constructeur d’un ouvrage est responsable de plein droit, envers le ma\u00eetre ou l’acqu\u00e9reur de l’ouvrage, des dommages, m\u00eame r\u00e9sultant d’un vice du sol, qui compromettent la solidit\u00e9 de l’ouvrage ou qui, l’affectant dans l’un de ses \u00e9l\u00e9ments constitutifs ou l’un de ses \u00e9l\u00e9ments d’\u00e9quipement, le rendent impropre \u00e0 sa destination.”<\/a> Every builder is automatically liable to the client for damage, even caused by the ground itself, that threatens the solidity of the building or makes it unfit for its purpose, whether through the structure or through fitted equipment. A collapsing extension wall, a roof that lets in water throughout the house, underfloor heating so undersized that the house cannot be heated in winter, as in the 2020 case above, all fall within this ten-year cover, and the liability is automatic, meaning you do not have to prove the builder was at fault, only that the damage meets the test.<\/p>\n Two further texts complete the picture. First, the category of people bound by these guarantees is wide: the Code treats as a builder “Tout architecte, entrepreneur, technicien ou autre personne li\u00e9e au ma\u00eetre de l’ouvrage par un contrat de louage d’ouvrage”<\/a>, that is, every architect, builder, technician or other person tied to the client by a works contract, alongside sellers of completed buildings and project managers acting as agents. Your mason, your roofer, your heating engineer and the main contractor who coordinated them can each be pursued. Second, the time limit is strict: the Code provides that “Toute personne physique ou morale dont la responsabilit\u00e9 peut \u00eatre engag\u00e9e en vertu des articles 1792 \u00e0 1792-4 du pr\u00e9sent code est d\u00e9charg\u00e9e des responsabilit\u00e9s et garanties pesant sur elle, en application des articles 1792 \u00e0 1792-2, apr\u00e8s dix ans \u00e0 compter de la r\u00e9ception des travaux ou, en application de l’article 1792-3 , \u00e0 l’expiration du d\u00e9lai vis\u00e9 \u00e0 cet article.”<\/a> After ten years from acceptance, or after the two-year period for equipment, the builder is released. Act within the period, and a court claim or even a proper expert procedure freezes the clock. Finally, check the project insurance, called assurance dommages-ouvrage<\/i>: the Insurance Code requires that the person having the works carried out “doit souscrire avant l’ouverture du chantier, pour son compte ou pour celui des propri\u00e9taires successifs, une assurance garantissant, en dehors de toute recherche des responsabilit\u00e9s, le paiement de la totalit\u00e9 des travaux de r\u00e9paration des dommages”<\/a>, meaning he must take out, before the site opens, insurance guaranteeing payment of all repair works for ten-year damage, without waiting for anyone’s liability to be established. If you or a previous owner took out this policy, it can fund the repairs quickly while the argument about fault continues separately. If nobody took it out, your claim runs directly against the builder and his own ten-year insurer, which is why obtaining his insurance certificate matters so much.<\/p>\n Where the builder walked off before any acceptance, these three guarantees have simply not started, and that is not a weakness: you fall back on the general law of contracts, which is often faster and more flexible. The builder who abandons the site breaches his obligation to perform, and the Code provides that “Le d\u00e9biteur est condamn\u00e9, s’il y a lieu, au paiement de dommages et int\u00e9r\u00eats soit \u00e0 raison de l’inex\u00e9cution de l’obligation, soit \u00e0 raison du retard dans l’ex\u00e9cution, s’il ne justifie pas que l’ex\u00e9cution a \u00e9t\u00e9 emp\u00each\u00e9e par la force majeure.”<\/a> The defaulting party pays damages for non-performance or for delay unless performance was truly prevented by an unforeseeable and irresistible event, called force majeure<\/i>. A busy order book, cash-flow problems or a better-paying job elsewhere are never force majeure<\/i>. Claims of this contractual kind are subject to the ordinary five-year time limit: “Les actions personnelles ou mobili\u00e8res se prescrivent par cinq ans \u00e0 compter du jour o\u00f9 le titulaire d’un droit a connu ou aurait d\u00fb conna\u00eetre les faits lui permettant de l’exercer.”<\/a> You have five years from the day you knew, or should have known, the facts, but there is no reason to wait: the site deteriorates, the evidence fades, and the builder may become insolvent.<\/p>\n French procedure offers you two complementary paths, and experienced owners often use both in sequence: a fast application to the urgent judge within weeks to secure money or protective measures, then a full trial to settle everything definitively. Nothing requires you to live in France to use either route: your lawyer can represent you, and documents can be signed at a distance. What matters is choosing the right door for your objective, since asking the fast judge for something he cannot give wastes precious months.<\/p>\n The fast route goes before the urgent applications judge, called the juge des r\u00e9f\u00e9r\u00e9s<\/i>, sitting at the local tribunal judiciaire<\/i>, the ordinary civil court. This judge does not decide the whole dispute definitively, but he can order immediate measures in weeks rather than the year or more a full trial takes. His powers come from the Code of Civil Procedure: “Le pr\u00e9sident du tribunal judiciaire ou le juge des contentieux de la protection dans les limites de sa comp\u00e9tence peuvent toujours, m\u00eame en pr\u00e9sence d’une contestation s\u00e9rieuse, prescrire en r\u00e9f\u00e9r\u00e9 les mesures conservatoires ou de remise en \u00e9tat qui s’imposent, soit pour pr\u00e9venir un dommage imminent, soit pour faire cesser un trouble manifestement illicite. Dans les cas o\u00f9 l’existence de l’obligation n’est pas s\u00e9rieusement contestable, ils peuvent accorder une provision au cr\u00e9ancier, ou ordonner l’ex\u00e9cution de l’obligation m\u00eame s’il s’agit d’une obligation de faire.”<\/a> Even where the other side disputes everything, the judge can order protective or restoration measures to prevent imminent damage or stop a manifestly unlawful nuisance, and wherever the obligation is not seriously open to dispute, he can grant the creditor an interim payment, called a provision<\/i>, or order the obligation to be performed even if it means doing building works. For you, this translates into concrete requests: an order forcing the builder to return and make the site watertight, an interim sum repaying your deposit for works never done, called the trop-per\u00e7u<\/i>, meaning the overpayment, or an advance on the cost of repairs.<\/p>\n This is not theory. In a decision of 14 February 2025, case number 24\/10386, the Paris Court of Appeal dealt with exactly your situation: a client who had paid a deposit of about 9,000 euros on a 30,000-euro flat renovation watched the contractor abandon the site in July 2023 and had to end the contract for the contractor’s exclusive fault. The urgent judge had “condamn\u00e9 la soci\u00e9t\u00e9 Groupe IDB \u00e0 payer \u00e0 Mme [T] [J] une provision de 8.265,79 euros TTC au titre du trop-per\u00e7u”<\/a>, ordered the company to pay back 8,265.79 euros as an interim payment for the overpayment, and on appeal the court simply “Confirme l’ordonnance entreprise”<\/a>, confirmed the order. The court recalled the governing test in full: “Dans les cas o\u00f9 l’existence de l’obligation n’est pas s\u00e9rieusement contestable, le pr\u00e9sident du tribunal judiciaire ou le juge des contentieux de la protection dans les limites de sa comp\u00e9tence peuvent accorder une provision au cr\u00e9ancier, ou ordonner l’ex\u00e9cution de l’obligation m\u00eame s’il s’agit d’une obligation de faire.”<\/a> Where the builder took money for works he never performed, the obligation to repay is not seriously open to dispute, and the interim payment follows. Your file for this application should therefore be short and sharp: the contract, the proof of payments, the bailiff’s report showing what was never done, the formal notice ignored by the builder, and the comparative quotes showing what completion will cost. A judge who sees money paid against an empty site understands the case in minutes.<\/p>\n The same urgent judge can also appoint an independent court expert before any trial, through what lawyers call a r\u00e9f\u00e9r\u00e9-expertise<\/i>. The Code allows this protective investigation generously: “S’il existe un motif l\u00e9gitime de conserver ou d’\u00e9tablir avant tout proc\u00e8s la preuve de faits dont pourrait d\u00e9pendre la solution d’un litige, les mesures d’instruction l\u00e9galement admissibles peuvent \u00eatre ordonn\u00e9es \u00e0 la demande de tout int\u00e9ress\u00e9, sur requ\u00eate ou en r\u00e9f\u00e9r\u00e9.”<\/a> If there is a legitimate reason to preserve or establish evidence before trial, investigation measures can be ordered on application. Ask for this expert appointment early whenever defects are technical or disputed: the court expert visits with both sides present, hears each party’s specialist, takes samples, and files a report that very often settles the case, because neither side can credibly contradict neutral findings. The expert procedure costs money, usually advanced by you and recovered from the losing party at the end, but it transforms an argument about cracks into measured findings with costed remedies. For a British owner, insist that your own technical adviser attends the expert meetings with you or for you, so that nothing is conceded in French that you have not understood, and have every key document translated.<\/p>\n Be realistic about the limits of the fast route. The urgent judge grants interim payments, not final damages for stress, lost rental income or the full cost of a replacement project where figures are hotly disputed. He can order the builder to make the roof watertight this month, but he will not finally resolve a three-way argument between you, the architect and three subcontractors about who designed the defective foundations. Treat the r\u00e9f\u00e9r\u00e9<\/i> as the emergency room: stop the bleeding, secure an advance, freeze the evidence with an expert, then move to the full claim for the complete cure. If the builder ignores even the urgent order, the judge can attach a daily financial penalty, called an astreinte<\/i>, meaning a fixed sum per day of delay, which concentrates minds wonderfully.<\/p>\n The full trial before the tribunal judiciaire<\/i> settles everything: who ended the contract and at whose fault, who pays for completion, which guarantees apply, and what damages are owed. Start with the contract itself. Where the builder has abandoned the site or refuses to repair serious defects, the non-performance will usually be serious enough to justify termination, called r\u00e9solution<\/i> or r\u00e9siliation<\/i>. The Code states that “La r\u00e9solution r\u00e9sulte soit de l’application d’une clause r\u00e9solutoire soit, en cas d’inex\u00e9cution suffisamment grave, d’une notification du cr\u00e9ancier au d\u00e9biteur ou d’une d\u00e9cision de justice.”<\/a> Termination follows either a termination clause in your contract or, where the breach is sufficiently serious, a notification you send to the builder or a court decision. In practice, after your formal notice has expired unanswered, your lawyer notifies termination for the builder’s exclusive fault, called r\u00e9siliation aux torts exclusifs de l’entreprise<\/i>, exactly as the client did in the Paris 2025 case. From that moment you are free to hire someone else, and the price difference becomes the builder’s bill: if the first builder was to finish for 20,000 euros and the replacement charges 27,000 euros for the same scope, the 7,000-euro gap is recoverable, supported by your comparative quotes and invoices.<\/p>\n You do not even have to wait for the final judgment to get the house finished. The Code allows you to have the works carried out by another firm and send the bill to the defaulting builder: “Apr\u00e8s mise en demeure, le cr\u00e9ancier peut aussi, dans un d\u00e9lai et \u00e0 un co\u00fbt raisonnables, faire ex\u00e9cuter lui-m\u00eame l’obligation ou, sur autorisation pr\u00e9alable du juge, d\u00e9truire ce qui a \u00e9t\u00e9 fait en violation de celle-ci. Il peut demander au d\u00e9biteur le remboursement des sommes engag\u00e9es \u00e0 cette fin. Il peut aussi demander en justice que le d\u00e9biteur avance les sommes n\u00e9cessaires \u00e0 cette ex\u00e9cution ou \u00e0 cette destruction.”<\/a> After the formal notice, within a reasonable time and at a reasonable cost, you may have the obligation performed yourself, or with the judge’s prior permission demolish what was wrongly done, claim reimbursement of the sums spent, and even ask the court to order the builder to advance the necessary funds. The conditions matter: a proper formal notice first, a reasonable replacement price proved by competing quotes, and for demolition or structural redoing, the judge’s prior permission. Follow them, and the replacement invoices become the backbone of your damages claim alongside the overpayment refund, the extra rent or hotel costs caused by the delay, the damage to furniture or belongings from water ingress, and compensation for the trouble and loss of enjoyment of your home.<\/p>\n At trial, direct your claims at everyone who may have to pay, not only the vanished builder. Every person treated as a builder within the wide definition of the works contract can be pursued, and their ten-year insurers with them, since the insurer who covers the builder’s ten-year liability answers for the same damage. Where the defects meet the ten-year test of threatening solidity or fitness for purpose, plead the automatic guarantee alongside the contract claim, so that even an argument about the seriousness of the breach cannot sink you: the guarantee needs no proof of fault. Where a project insurance policy exists, call the dommages-ouvrage<\/i> insurer into the case so that repairs can be funded without waiting for the apportionment of blame between the builder, the architect and the subcontractors. Ask the court to make the builder’s insurer produce the policy and the Triggering documents, and challenge any refusal to cover: an insurer who denies cover for a plainly structural disorder, or who relies on unpaid premiums to abandon a consumer, must explain itself to the judge with the policy wording in hand. If the builder has gone bust, his ten-year insurer generally remains answerable for guarantee damage, which is precisely why identifying the insurer at the start is so valuable, and why proceedings can continue usefully even against an insolvent firm.<\/p>\n A final word on defending the claim against counterattack, because abandoning builders often invoice fictitious extras or allege that you prevented the works. French judges see these defences weekly. Extras are only payable if you actually ordered them or necessarily agreed them, so an invoice for works never discussed in writing and never accepted will fail against your file of contract, quotes and bailiff’s report. Delay blamed on you fails against your dated letters urging the builder to return. And an allegation that you accepted the works without complaint collapses where there is no signed acceptance report and the defects speak through the expert’s photographs. Keep every document for at least ten years after the end of the works, keep a simple chronology from first quote to last letter, and never agree orally to changes: confirm everything the same day by email, so the paper trail tells the story even if witnesses forget.<\/p>\n An abandoned site or a botched renovation in France is not the end of your project; it is the start of a well-marked legal path. Prove the failure with the contract, the payments, the dated photographs and above all the bailiff’s report and the ignored formal notice. Identify whether acceptance has happened, expressly, tacitly through possession and full payment, or not at all, because that date starts the one-year, two-year and ten-year guarantees. Use the urgent judge quickly for an interim repayment, an order to make safe, or a court expert who freezes the technical truth. Then pursue the full claim: termination for the builder’s exclusive fault, completion by a replacement firm at a reasonable price, repayment of the overpayment, and damages for delay and loss of enjoyment, directed at the builder and every available insurer including the project insurer. Move within the time limits: years run from acceptance for the guarantees, and five years from knowledge for contract claims, so early action protects both the house and the claim. Above all, stop communicating orally and put everything in writing from today. If you act methodically, the same French law that once looked like a foreign maze becomes a lever that brings the builder back to the table, or makes someone else pay for finishing properly what he started.<\/p>\n A half-finished house or a spreading defect cannot wait.
