French CCMI Delivery Delays in 2026: Can a Builder Blame the Buyer’s Late Payments?

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 (CCMI, an individual-house construction contract).

The issue has become particularly clear after the Third Civil Chamber’s 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’s 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.

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.

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.

I. The 2026 rule: payment disputes do not automatically extend delivery

A. What the CCMI must say before construction begins

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 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.

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.

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’s scope, the owner’s scope, or the guarantee’s coverage. A translation used by a broker is not a replacement for the French signed contract and its technical notice.

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’s bank, solicitor, broker, or attorney is in another country.

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.

In Cass. 3e civ., 25 June 2026, no. 24-16.541, the Court stated: “les travaux étaient réceptionnés, les maîtres de l’ouvrage ayant pris possession de la maison”. 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’s payment mechanics while rejecting an unlawful extension of the delivery date.

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’s email saying “the house is ready” 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.

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.

The payment timetable must also be compared with the site’s 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.

B. What the 25 June 2026 decision changes

The central statutory safeguard appears in Article L.231-3 of the Construction and Housing Code. 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’s right to visit the site.

The short French sentence relied on by the Court was: “sont réputées non écrites, les clauses ayant pour objet ou pour effet de décharger le constructeur de son obligation d’exécuter les travaux dans les délais prévus par le contrat”. 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’s 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.

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’s reasoning and then rejected it: “En statuant ainsi, sur le seul fondement d’une clause, réputée non écrite, la cour d’appel a violé le texte susvisé.” 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.

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.

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.

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: “l’acquéreur non professionnel peut se rétracter dans un délai de dix jours”. 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’ status, the notification method, and the applicable version of the law.

The buyer’s 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.

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’s 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.

II. Remedies, guarantee procedure, and an international buyer’s checklist

A. Penalties, guarantee coverage, and evidence of causation

The minimum level of CCMI delivery penalties is stated in Article R.231-14 of the Construction and Housing Code: “les pénalités prévues au i de l’article L. 231-2 ne peuvent être fixées à un montant inférieur à 1/3 000 du prix convenu par jour de retard”. 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.

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, 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.

The relevant French passage was: “les pénalités de retard ont pour terme la livraison de l’ouvrage et non sa réception”. 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.

In Cass. 3e civ., 16 January 2025, no. 23-14.655, the Court addressed the argument that the owners’ unpaid calls made them exclusively responsible for the late delivery. It held: “La faute du maître de l’ouvrage ne peut exonérer intégralement le constructeur du paiement des pénalités … que si elle présente les caractéristiques de la force majeure ou en constitue la cause exclusive.” The principle is demanding. A buyer’s fault does not completely remove penalties unless it amounts to force majeure or is the exclusive cause of the delay.

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.

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.

The delivery guarantee is a separate protection. Article L.231-6 of the Construction and Housing Code 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’s conduct that caused an advance payment or price supplement, and contractual delay penalties exceeding thirty days.

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.

In Cass. 3e civ., 11 May 2023, no. 21-23.859, the Court considered a missing delivery guarantee and the lender’s responsibility for releasing funds without the required certificate. It held that the guarantee covers delay penalties exceeding thirty days and that the bank’s failure had caused certain loss rather than merely a speculative loss of opportunity. The French wording included: “le constructeur … doit souscrire une garantie de livraison”. For a buyer, the lesson is to verify the certificate before the financing is drawn and to preserve the lender’s compliance documents.

But coverage is not unlimited. In Cass. 3e civ., 13 April 2023, no. 21-21.106, the Court held: “sauf clause contraire contenue dans le contrat de garantie, le garant n’est pas tenu de prendre à sa charge les dommages-intérêts … distincts du coût d’achèvement”. The delivery guarantor’s 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.

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’s findings.

In Cass. 3e civ., 26 March 2026, no. 24-14.789, 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: “la durée des opérations d’expertise … ne constituait pas, faute d’extériorité, un cas de force majeure exonératoire”. In English, an event connected with the builder’s own construction dispute may lack the required external character to excuse the builder. The label “expert delay” does not decide the issue.

Finally, Cass. 3e civ., 5 June 2025, no. 23-19.712 confirms that a construction professional can be liable for damage resulting from a proven failure to deliver on the agreed date. The Court wrote: “le non-respect par … [le constructeur] de son obligation de livraison à date avait causé un préjudice”. Although that case concerned a larger construction operation and an arbitral decision, it reinforces the importance of the agreed delivery obligation and causal proof.

B. A practical protocol for buyers based outside France

Start with a document audit. Obtain the signed CCMI, all amendments, the technical notice, plans, price breakdown, payment schedule, guarantee certificate, insurance documents, building permit, site-opening declaration, invoices, bank confirmations, and reception records. Create a chronology in French dates using day-month-year format. Mark each document as signed, received, paid, disputed, or awaiting clarification. Do not rely on a portal where earlier versions can disappear.

Next, isolate the payment allegation. For each disputed call for funds, record the contractual stage, date of issue, due date, amount, bank transfer date, and evidence of the corresponding work. If the builder claims that a payment delay stopped work, request a written explanation identifying the stoppage date, affected trades, resumed date, and contractual and statutory basis. Ask whether the builder is invoking force majeure, bad weather, a fortuitous event, an owner-reserved work item, or only the disputed clause.

Then inspect the delivery deadline. Compare the original deadline with every amendment and with the date on which the builder says the site was complete. A valid amendment may change the timetable, but a clause cannot simply add a prohibited excuse because it appears in small print. The parties’ conduct can also create factual disputes about waiver or acceptance. Obtain legal advice before signing an acknowledgement that describes a new date as accepted or waives penalties.

Keep communications factual. A useful letter can state that the owner contests the proposed extension, reserves all rights concerning delay penalties, requests the supporting calculation, and remains willing to pay sums properly due under the contract, subject to the applicable procedure. It can also request a meeting and a jointly signed site report. Avoid threats, accusations of fraud, or statements that the entire price will never be paid.

Notify the guarantor promptly. Attach the guarantee certificate and the builder’s notice, explain the missed date or unfinished works, and request confirmation of the next procedural step. Send by a method that proves receipt. If the guarantor says that the builder is not in default because of owner non-payment, ask it to identify the precise period and evidence relied upon. A foreign address or a French mobile number should not be allowed to create uncertainty about service.

Protect the handover. Attend reception in person or appoint a qualified representative. Record reservations precisely, with photographs and room references. Do not sign a document stating that all works are complete if significant works remain. If keys are offered against full payment while reservations exist, review the escrow and consignment mechanism before deciding. Article L.231-3 specifically protects the owner’s ability to consign sums remaining due when reservations are made, but the contractual and factual conditions must be checked.

Consider urgency separately from the merits. If the builder abandons the site, the home is unsafe, or the guarantor does not act after formal notice, a court application may be needed quickly. An interim procedure may seek an expert, completion measures, or a provisional payment where the legal conditions are met. A merits action may later address penalties, price, defects, and consequential loss. The owner should not assume that the fastest procedure determines every issue permanently.

For non-resident owners, tax and financing consequences should be flagged but not confused with the construction claim. A delayed rental start may affect projected income, loan interest, insurance, or a future sale. Those consequences need evidence and may have separate tax treatment in France and the owner’s country of residence. Obtain tax advice from a qualified adviser familiar with the relevant residence and treaty position. Do not present a construction-law letter as a tax opinion.

Use qualified professionals for technical evidence. A French building expert can distinguish incomplete work, defective work, owner-reserved work, and a payment-related stoppage. A translated summary from a foreign surveyor may be useful, but the court will need evidence that addresses the French contract and site. Ask the expert to identify dates, causation, estimated completion cost, habitability, and the difference between reception and delivery.

Finally, use the restricted internal route for a French real-estate consultation if the dispute requires a case-specific review. The firm’s English real-estate page is Kohen Avocats real-estate law attorneys in Paris. The page does not replace a review of the contract and evidence, and no outcome can be promised.

Conclusion

The 25 June 2026 decision gives foreign CCMI buyers a clear warning about broad payment-delay clauses. A builder cannot rely solely on a clause that allows every late payment to extend delivery, because Article L.231-3 treats clauses of that kind as unwritten. At the same time, the decision does not erase the buyer’s duty to pay sums properly due or the consequences of a proven breach.

The correct method is chronological and document-based. Establish the contractual deadline, identify each payment and its due date, test the actual causal effect of any non-payment, calculate penalties under the contract and Article R.231-14, and notify the delivery guarantor under Article L.231-6. Keep the French originals, obtain a reliable translation, and separate completion costs, delay penalties, defects, temporary accommodation, rental loss, financing, and tax questions.

For a buyer based in the United Kingdom, the United States, or Australia, distance increases the risk of missed notices and undocumented site events. A dated file, prompt formal notice, qualified technical evidence, and advice on the signed French documents can prevent a disagreement about payment from becoming an uncontrolled dispute about delivery.
