For a foreign buyer building a home in France, a payment dispute can quickly become a delivery dispute. A builder may say that an unpaid call for funds stopped the works, extended the contractual completion date, and removed the right to delay penalties. That position must be tested against the specific construction contract and the mandatory rules governing a contrat de construction de maison individuelle<\/em> (CCMI, an individual-house construction contract).<\/p>\n The issue has become particularly clear after the Third Civil Chamber\u2019s decision of 25 June 2026, no. 24-16.541. The decision concerned a CCMI, a delivery guarantee, staged payments, and a contractual clause allowing the builder to rely on the client\u2019s payment delays to extend delivery. The Court of Cassation held that a court could not base the extension on that clause because the clause was deemed unwritten. The result does not mean that a buyer may simply stop paying. It means that the contractual timetable, payment schedule, evidence, and statutory guarantee must be analysed separately.<\/p>\n This guide explains the practical consequences for buyers living abroad, non-resident owners, and families financing a French build from the United Kingdom, the United States, or Australia. It is not a substitute for reviewing the signed CCMI, the calls for funds, bank records, site reports, and correspondence in the individual case.<\/p>\n The article also places the 2026 ruling in the context of five other decisions obtained from the official judicial corpus during this review. The linked decisions are French-language primary materials. Their practical meaning is explained in English for an international reader.<\/p>\n A CCMI is not an ordinary quotation followed by informal building work. Its mandatory content is important because it fixes the financial and temporal framework in which later arguments will be assessed. Article L.231-2 of the French Construction and Housing Code<\/a> requires the contract to identify the land, describe the building and its technical characteristics, state the agreed price and the cost of works reserved by the owner, explain the payment stages, identify the opening date and execution period, and state the penalties for late delivery. It must also contain evidence of the repayment and delivery guarantees.<\/p>\n For a buyer unfamiliar with French construction vocabulary, the payment schedule is not merely an administrative annex. The calls for funds are tied to progress of the works. A request that does not correspond to the contractual stage, or that is issued before the relevant work has been completed, may create a dispute about whether the amount was due. Conversely, a call that is contractually due remains a serious obligation even when the buyer is unhappy with workmanship. The buyer should therefore avoid reducing or withholding payments informally and should obtain advice before treating defects as a justification for non-payment.<\/p>\n The same provision requires the contract to describe and price works that the owner reserves. This matters where a foreign buyer believes that landscaping, connections, painting, a driveway, or external works were included in the headline price. The written description and the signed cost breakdown may determine whether an item belongs to the builder\u2019s scope, the owner\u2019s scope, or the guarantee\u2019s coverage. A translation used by a broker is not a replacement for the French signed contract and its technical notice.<\/p>\n Article L.231-2 also connects the contractual price to the delivery guarantee. The guarantee is not an optional commercial reassurance. It is part of the protective framework of the CCMI. Before releasing funds, the buyer should keep the guarantee certificate, the identity of the guarantor, the contract, the technical notice, the financing offer, and every call for funds in one dated file. This is especially important when the buyer\u2019s bank, solicitor, broker, or attorney is in another country.<\/p>\n The 2026 decision illustrates why the documents must be read together. The Court recorded that the contract provided for staged payment as work progressed and that the builder sought payment of the fraction due on completion of works, while the five per cent fraction due at reception was being held in escrow. The payment issue could not be separated from the completion and reception stages. A buyer should not assume that every sum demanded immediately before handover has the same legal status.<\/p>\n In Cass. 3e civ., 25 June 2026, no. 24-16.541<\/a>, the Court stated: \u201cles travaux \u00e9taient r\u00e9ceptionn\u00e9s, les ma\u00eetres de l\u2019ouvrage ayant pris possession de la maison\u201d. The point was that, on the facts found by the lower court, the works were complete for the relevant payment fraction because reception had occurred and the owners had taken possession. The decision therefore protects the contract\u2019s payment mechanics while rejecting an unlawful extension of the delivery date.<\/p>\n Foreign buyers should distinguish three dates: the contractual opening of the site, the contractual delivery deadline, and actual delivery. A fourth date, reception, can be different again. Possession, connection to utilities, habitability, reservations, and formal reception may all affect the analysis. A builder\u2019s email saying \u201cthe house is ready\u201d is not necessarily the same as a documented delivery. The buyer should request a formal meeting, a written report, and a precise list of remaining items.<\/p>\n Language creates a practical risk. A buyer may receive a French notice, understand that payment is requested, and miss a technical or procedural deadline. Do not rely on an automatic translation for a document that changes the delivery date, alleges default, threatens termination, or invokes the guarantee. Preserve the original French document, its envelope or transmission metadata, and a working translation. Record who sent it, when it was received, and which contractual clause is being invoked.<\/p>\n The payment timetable must also be compared with the site\u2019s actual progress. Keep dated photographs, architect or engineer reports, meeting minutes, invoices, bank confirmations, and delivery records. A spreadsheet can show the date, amount, contractual stage, supporting evidence, date paid, and any reservation. This basic chronology is often more useful than a long exchange of accusatory emails.<\/p>\n The central statutory safeguard appears in Article L.231-3 of the Construction and Housing Code<\/a>. It provides that clauses intended to release the builder from the obligation to perform within the contractual period by adding legitimate causes of delay beyond the statutory categories are deemed unwritten. The official text expressly refers to causes other than bad weather, force majeure, and fortuitous events. It also addresses other protective matters, including the handing over of keys and the owner\u2019s right to visit the site.<\/p>\n The short French sentence relied on by the Court was: \u201csont r\u00e9put\u00e9es non \u00e9crites, les clauses ayant pour objet ou pour effet de d\u00e9charger le constructeur de son obligation d\u2019ex\u00e9cuter les travaux dans les d\u00e9lais pr\u00e9vus par le contrat\u201d. In English, the clause is treated as if it had never been written when its effect is to free the builder from the agreed time obligation by adding an impermissible excuse. The Court\u2019s reasoning is not a general licence to ignore a genuine buyer default. It is a refusal to let a pre-drafted clause decide causation without applying the mandatory rule.<\/p>\n In the 2026 case, the clause allowed the builder to rely on payment delays attributable to the owners to interrupt the site and extend the delivery date. The Court summarised the lower court\u2019s reasoning and then rejected it: \u201cEn statuant ainsi, sur le seul fondement d’une clause, r\u00e9put\u00e9e non \u00e9crite, la cour d’appel a viol\u00e9 le texte susvis\u00e9.\u201d The practical message is direct. A builder must establish the legal basis and factual causation of the alleged delay; it cannot rely only on a broad contractual extension clause that the statute neutralises.<\/p>\n This distinction is essential for an international owner. A late payment may still have consequences under the contract. It may justify a claim for interest, a suspension that is legally permitted, or a claim for loss caused by a proven breach. But it does not automatically move the contractual delivery deadline. The builder must show what payment was due, when it was due, whether it was unpaid, what work could not proceed, for how long, and whether the alleged event legally qualifies as an excusing cause.<\/p>\n The decision also concerned works that were in the contractual field but had not been priced realistically. The Court held that works appearing in the contract or plans had to be quantified, even where the owners had reserved their execution. For a foreign buyer, that is a warning against accepting a headline price without checking the technical notice, plans, external works, connections, and owner-reserved items. An apparently low price can conceal a later dispute about who must pay for work necessary to complete the home.<\/p>\n The Court also referred to the ten-day withdrawal rule for an act concerning construction or acquisition of a residential building. The French text was: \u201cl’acqu\u00e9reur non professionnel peut se r\u00e9tracter dans un d\u00e9lai de dix jours\u201d. In the case, the Court held that an amendment affecting a mandatory element had not been properly notified and that the withdrawal period had therefore not started. This is a technical point, not a routine cancellation right. It should not be applied without checking the type of document, the parties\u2019 status, the notification method, and the applicable version of the law.<\/p>\n The buyer\u2019s first response should therefore be measured. Ask the builder to identify the precise unpaid call, contractual due date, work stage, amount, and clause relied upon. Ask for the calculation of the proposed extension and the evidence linking the non-payment to the actual interruption. Do not admit liability in broad terms. Equally, do not assert that all payments are suspended merely because there are defects. A carefully worded reservation preserves options without creating a new default.<\/p>\n If the builder threatens to stop work, the buyer should immediately notify the guarantor as well as the builder. Send the contract, guarantee certificate, payment chronology, delivery deadline, photographs, and correspondence. Request confirmation of the guarantor\u2019s position and the procedure for intervention. The buyer should also ask the notary or financing bank what payments remain blocked, what sum is held, and what release conditions apply. These steps create an auditable record while the dispute is still manageable.<\/p>\n The minimum level of CCMI delivery penalties is stated in Article R.231-14 of the Construction and Housing Code<\/a>: \u201cles p\u00e9nalit\u00e9s pr\u00e9vues au i de l’article L. 231-2 ne peuvent \u00eatre fix\u00e9es \u00e0 un montant inf\u00e9rieur \u00e0 1\/3 000 du prix convenu par jour de retard\u201d. In practical terms, the contractual penalty cannot be set below one three-thousandth of the agreed price per day of delay. The same article permits a payment-delay penalty charged to the owner, but caps its rate at one per cent per month on unpaid sums where the delivery penalty is limited to the statutory minimum.<\/p>\n The calculation still requires a reliable start and end date. The delivery deadline must be established from the CCMI and any valid amendment. The actual end date must reflect delivery, not simply the date on which a builder says that reception is possible. In Cass. 3e civ., 22 January 2026, no. 23-23.916<\/a>, the Court recalled the distinction between delivery and reception and required the lower court to examine whether the building was habitable at the alleged possession date because the electrical compliance document had not been supplied.<\/p>\n The relevant French passage was: \u201cles p\u00e9nalit\u00e9s de retard ont pour terme la livraison de l’ouvrage et non sa r\u00e9ception\u201d. The English consequence is that reception does not necessarily end the penalty period. If the house cannot lawfully or practically be occupied, the date described as possession may not be the end of the delay. A foreign buyer should preserve evidence about utilities, electricity compliance, water, heating, access, safety, and whether the premises could actually be used for their intended residential purpose.<\/p>\n In Cass. 3e civ., 16 January 2025, no. 23-14.655<\/a>, the Court addressed the argument that the owners\u2019 unpaid calls made them exclusively responsible for the late delivery. It held: \u201cLa faute du ma\u00eetre de l’ouvrage ne peut exon\u00e9rer int\u00e9gralement le constructeur du paiement des p\u00e9nalit\u00e9s … que si elle pr\u00e9sente les caract\u00e9ristiques de la force majeure ou en constitue la cause exclusive.\u201d The principle is demanding. A buyer\u2019s fault does not completely remove penalties unless it amounts to force majeure or is the exclusive cause of the delay.<\/p>\n The Court then noted that the unpaid calls were made after the contractual delivery date. It held that those later non-payments could not be the exclusive cause of a delay that had already matured. This is a useful chronology rule. A builder cannot use a payment made late after the deadline to explain a period of delay that existed before the payment was due. The chronology must be tested day by day, not asserted globally.<\/p>\n The 2026 decision is consistent with that reasoning but concerns a different contractual structure. It rejects the clause as a source of automatic extension. Together, the decisions mean that an owner should ask two separate questions: was there a genuine payment breach, and did that breach legally and factually cause a specific period of delay? The answer to the first question does not automatically answer the second.<\/p>\n The delivery guarantee is a separate protection. Article L.231-6 of the Construction and Housing Code<\/a> says that the guarantee covers the owner from the opening of the site against non-performance or poor performance of the contractual works at the agreed price and time. In the event of builder default, it covers certain price overruns necessary for completion, consequences of the builder\u2019s conduct that caused an advance payment or price supplement, and contractual delay penalties exceeding thirty days.<\/p>\n The statute provides a procedural sequence. When the guarantor identifies a missed delivery period or uncompleted works needed to remove reception reservations, it must put the builder on notice without delay. The same obligation applies when the owner informs the guarantor. If the notice remains ineffective for fifteen days, the guarantor proceeds under the statutory mechanism. The owner should therefore send a clear notice, identify the contract and guarantee, describe the default, and request action. An informal message to a sales agent may not be enough.<\/p>\n In Cass. 3e civ., 11 May 2023, no. 21-23.859<\/a>, the Court considered a missing delivery guarantee and the lender\u2019s responsibility for releasing funds without the required certificate. It held that the guarantee covers delay penalties exceeding thirty days and that the bank\u2019s failure had caused certain loss rather than merely a speculative loss of opportunity. The French wording included: \u201cle constructeur … doit souscrire une garantie de livraison\u201d. For a buyer, the lesson is to verify the certificate before the financing is drawn and to preserve the lender\u2019s compliance documents.<\/p>\n But coverage is not unlimited. In Cass. 3e civ., 13 April 2023, no. 21-21.106<\/a>, the Court held: \u201csauf clause contraire contenue dans le contrat de garantie, le garant n’est pas tenu de prendre \u00e0 sa charge les dommages-int\u00e9r\u00eats … distincts du co\u00fbt d’ach\u00e8vement\u201d. The delivery guarantor\u2019s statutory role is not automatically a general insurance policy for every consequential loss. Temporary accommodation, moving costs, financing costs, lost rent, or emotional harm may require a different legal basis and evidence.<\/p>\n This boundary matters to non-residents. A buyer who planned to rent the completed home may have a claim against an appropriate party, but should not assume that the delivery guarantor will pay every lost rental month. Keep the rental mandate, expected dates, actual offers, financing costs, and proof of mitigation. If the home is a family residence, keep evidence of alternative accommodation and additional travel. The legal route and recoverable heads of loss depend on the contract, the guarantee, the cause, and the court\u2019s findings.<\/p>\n In Cass. 3e civ., 26 March 2026, no. 24-14.789<\/a>, the Court examined the point at which the site could begin, the delivery guarantee, and a force-majeure argument based on expert proceedings. It stated: \u201cla dur\u00e9e des op\u00e9rations d’expertise … ne constituait pas, faute d’ext\u00e9riorit\u00e9, un cas de force majeure exon\u00e9ratoire\u201d. In English, an event connected with the builder\u2019s own construction dispute may lack the required external character to excuse the builder. The label \u201cexpert delay\u201d does not decide the issue.<\/p>\nI. The 2026 rule: payment disputes do not automatically extend delivery<\/h2>\n
