Your developer has stopped answering emails, scaffolding has not moved for weeks, and a letter from a court-appointed administrator announces that the company building your future flat is in insolvency proceedings. For a foreign buyer who purchased off-plan in France, this is the nightmare scenario: a large share of the price is already paid, the flat does not exist yet, and the legal system feels opaque from abroad. French law, however, was designed precisely for this risk. Every lawful off-plan sale carries a mandatory financial safety net, stage payments are capped by statute, and the courts have settled who must prove what when the money is on the line. This guide explains, step by step, how the protection works, how to call on the guarantor, and how to defend the related fronts of penalties, delivery and defects, with the decisions and statutory texts that actually govern them. The following discussion is general in scope: it describes the verifications that are useful in any comparable situation and does not describe the situation of any particular developer, about which this article makes no finding.
I. The safety net built into every lawful off-plan sale
Buying a flat that does not yet exist is an act of trust, and French law refuses to leave that trust unsecured. The vente en l’état futur d’achèvement (sale in the future state of completion), universally known as VEFA, is the contract by which the seller “transfère immédiatement à l’acquéreur ses droits sur le sol ainsi que la propriété des constructions existantes”, as Article 1601-3 of the Civil Code provides. More broadly, “La vente d’immeubles à construire est celle par laquelle le vendeur s’oblige à édifier un immeuble dans un délai déterminé par le contrat”, in the words of Article 1601-1 of the Civil Code. Two consequences flow from this definition that matter enormously when the developer fails. First, the buyer becomes owner of what is built as it is built: “Les ouvrages à venir deviennent la propriété de l’acquéreur au fur et à mesure de leur exécution ; l’acquéreur est tenu d’en payer le prix à mesure de l’avancement des travaux.” Second, the seller keeps the powers of the project owner until acceptance of the works, which means the seller, not the buyer, bears the construction risk during the building phase. Understanding this allocation is the foundation of everything that follows: money already paid corresponds to works already owned, and the completion of the rest is secured by a third party.
A. Two guarantees, capped stage payments and the papers to keep
No developer may sell off-plan without backing the sale with one of two financial guarantees subscribed with a bank or insurer. The first is the garantie financière d’achèvement (financial completion guarantee): if the seller defaults, the guarantor funds the completion of the building so the buyer still receives the flat. The second is the garantie financière de remboursement (financial refund guarantee): if the sale is resolved for lack of completion, the guarantor repays the sums the buyer has already paid. The identity of the guarantee, the name of the guarantor and the reference of the deed must appear in the sale contract itself, and the buyer should keep the authentic deed of sale, every payment receipt, the reservation contract and all site-progress reports together, ideally as scanned copies accessible from abroad. When insolvency strikes, these documents are the file: the guarantor will ask for them, the administrator will ask for them, and any court will ask for them.
The sums at stake are framed by a strict statutory schedule. Article R.261-14 of the Construction and Housing Code provides that “Les paiements ou dépôts ne peuvent excéder au total : 35% du prix à l’achèvement des fondations ; 70% à la mise hors d’eau ; 95% à l’achèvement de l’immeuble.” No payment beyond these ceilings can be lawfully demanded, whatever the contract says, and a developer in cash-flow trouble that presses a foreign buyer for an “advance” above the cap is already signalling distress. The same article adds a protection that becomes central at delivery time: “Le solde est payable lors de la mise du local à la disposition de l’acquéreur ; toutefois il peut être consigné en cas de contestation sur la conformité avec les prévisions du contrat.” The final balance can therefore be frozen with a trusted third party instead of handed over when the flat does not match what was promised. Note also the monthly cap on the buyer’s own exposure: “Si le contrat prévoit une pénalité de retard dans les paiements ou les versements, le taux de celle-ci ne peut excéder 1% par mois.” Finally, if the sale was signed under a condition precedent such as obtaining a loan, “aucun versement ni dépôt ne peut être effectué avant la réalisation de cette condition.” A foreign buyer financing the purchase with a French mortgage should therefore verify that no funds were called before the loan offer became final.
A practical warning for buyers paying from abroad: make every stage payment by bank transfer to the account stated in the authentic deed, keep the transfer slips showing the contractual stage they correspond to, and never pay into a different account on the basis of an email instruction received mid-programme. Fraudulent change-of-bank-details messages statistically strike during construction programmes, and a buyer who can match each payment to a certified stage of completion is in a far stronger position if the developer later collapses.
B. When the developer collapses: calling the guarantor and choosing between completion and refund
Insolvency in France follows its own vocabulary that the foreign buyer will meet immediately. The developer is placed under redressement judiciaire (court-supervised recovery) and, if recovery proves impossible, under liquidation judiciaire (court-ordered liquidation). A court-appointed administrator or liquidator takes control, works usually stop, and the buyer receives formal notice to declare any claim. The first reflex is to check which of the two guarantees backs the sale and to write to the guarantor without delay, sending the deed, the payment receipts and the insolvency judgment. Under a completion guarantee, the guarantor must finance the finishing of the building; under a refund guarantee, the buyer seeks resolution of the sale and repayment. The choice is strategic and fact-dependent: a nearly finished building in a sought-after area points towards completion, while a barely started programme with a refund guarantee may point towards getting the money back and walking away. Either route runs through strict declarations and deadlines in the insolvency proceedings, so the buyer living abroad should organise representation in France early rather than discovering the timetable after it has closed.
The decisive legal question, once the guarantor is in the picture, is who must prove what about the money. The Court of Cassation answered it clearly in a case where a completion guarantor that had taken over unfinished works claimed the full balance of the price from the buyers. The Third Civil Chamber held that “il appartenait au garant de prouver qu’il avait financé la réalisation des ouvrages correspondant au solde du prix qu’il réclamait”, and quashed the appeal ruling that had reversed that burden (Cass., 3rd civ., 11 May 2023, no. 22-13.696). In plain English: the guarantor that demands the remaining price must prove it actually funded the corresponding works; it cannot bill the buyer for works the buyer paid for directly or that were never performed under the guarantee. For the foreign buyer, the practical lesson is to document everything the buyer financed outside the developer’s circuit, such as finishing works paid to another contractor under a side agreement, because those sums come off the balance the guarantor can claim. Keep invoices, proof of payment and any written agreement with the developer’s representative: in the reported case, exactly such a side protocol decided several million francs of liability.
A second frequent battle concerns delay. Insolvency freezes the site for months, and the buyer will want compensation for the late delivery on top of the completion itself. French VEFA contracts normally contain a penalty clause for late delivery, and the courts treat that clause as the natural measure of the loss of use, running until the building is genuinely completed. Completion, however, is a legal concept, not a feeling. In a 2025 ruling, the Court of Cassation approved judges who had fixed completion at the date the utility-compliance certificates were handed over, because before that date the building could not be regarded as habitable, holding that “les pénalités de retard étaient dues jusqu’à cette date” (Cass., 3rd civ., 13 Feb. 2025, no. 23-17.755). A developer or guarantor that argues the building was “substantially finished” months earlier must therefore be met with the habitability test: without the certificates that allow gas and electricity contracts to be opened, the flat cannot be lived in, and penalties keep running. Conversely, buyers should expect the other side to invoke contractually listed lawful causes of delay, such as weather days recorded under the contract’s own method or administrative shutdowns, and should demand the daily site records rather than accepting a lump assertion of hundreds of excused days.
Delay also interacts with the buyer’s own payment discipline in a way that surprises many foreigners. A developer that is itself late sometimes argues that the buyer paid late and that the two delays cancel out, or it claims contractual penalties against the buyer. The Court of Cassation settled the principle in a VEFA dispute: “la stipulation de sanctions à l’inexécution du contrat n’exclut pas la mise en oeuvre des solutions issues du droit commun des obligations” (Cass., 3rd civ., 14 Feb. 2019, no. 17-31.665). In other words, the existence of penalty clauses in the contract does not prevent a party from relying on ordinary contract-law remedies, including the exception d’inexécution (the right to suspend one’s own performance while the other side does not perform). Each side’s breach is therefore assessed on its own terms: the developer cannot hide behind the buyer’s late stage payment to escape liability for months of site standstill, and the buyer cannot invoke the developer’s difficulties to stop paying sums that are genuinely due under the capped schedule. From abroad, the safest conduct is to keep paying what is contractually due on time, by traceable transfer, while reserving all rights in writing: a buyer in good standing negotiates and litigates from strength.
II. Money, delivery and defects around the failure
Insolvency is rarely a single clean event; it arrives surrounded by missed deadlines, disputed payments and, once the flat is finally handed over, defects that the troubles of the construction period help explain. The buyer must manage these three fronts together, because a mistake on one weakens the others: paying an uncapped sum destroys leverage, accepting delivery without reservations destroys proof, and letting a deadline pass destroys the claim itself.
A. Stage payments under pressure and the day of delivery
When a developer wobbles, the pressure on cash is felt first by buyers: calls for early payment, requests to pay the balance before the flat is available, or penalties invoiced for alleged late payment. The answers are statutory. No payment above the 35/70/95 per cent stages of Article R.261-14 of the Construction and Housing Code can be required; any buyer-side late-payment penalty is capped at 1 per cent per month; and nothing at all may be paid before a loan condition precedent is fulfilled. A buyer who receives an irregular demand should answer in writing, cite the stage actually certified by the project supervisor, and pay strictly what is due. If the developer’s default ripens into resolution of the sale, the refund guarantee returns the sums paid, which is precisely why keeping each payment matched to a certified stage matters: it makes the claim against the guarantor arithmetic rather than argument.
Delivery day, the mise à disposition (making the unit available to the buyer), deserves the same discipline. The balance of the price is due at that moment, but the statute allows it to be frozen instead. Article R.261-14 of the Construction and Housing Code states: “Le solde est payable lors de la mise du local à la disposition de l’acquéreur ; toutefois il peut être consigné en cas de contestation sur la conformité avec les prévisions du contrat.” Consignation with the Caisse des dépôts et consignations (the public deposits fund) or a notary is the correct move when the flat visibly departs from the contract: missing fittings, wrong floor area, substituted materials, unfinished common areas. The buyer who consigns rather than pays keeps full leverage for the snagging phase, while the buyer who pays the whole balance to “get the keys faster” will chase reimbursement later from a company that may no longer exist. Foreign buyers who cannot attend in person can grant a power of attorney to a trusted representative with explicit instructions to record reservations, and should insist on receiving the delivery report, photographs and the list of reservations the same day.
Two traps specific to buyers living abroad deserve emphasis. First, the reservation contract signed at the outset, the contrat de réservation (preliminary reservation agreement), with its deposit and its cooling-off rights, is a separate document from the authentic deed of sale; disputes about refund of that deposit obey their own rules and their own short deadlines, and must not be confused with the guarantee machinery described above. Second, co-ownership life starts at delivery: service charges, the first general meeting and the handover of the common areas by the developer-appointed manager all begin while the buyer is still dealing with the insolvency. Voting by correspondence or proxy at the first meetings of the copropriété (co-ownership) prevents decisions being taken without the absent owner, and the buyers as a group are the natural party to press the guarantor and the administrator together rather than each alone. Readers dealing with the broader purchase process may also consult the overview of working with a real estate team in Paris advising foreign buyers on acquisitions, financing and disputes.
B. Defects after handover: the one-year net and the ten-year net
A troubled construction programme often produces a troubled building, so the defects regime is the second half of the insolvency story. French law gives the off-plan buyer two successive nets. The first is the year of apparent defects. Article 1642-1 of the Civil Code provides that “Le vendeur d’un immeuble à construire ne peut être déchargé, ni avant la réception des travaux, ni avant l’expiration d’un délai d’un mois après la prise de possession par l’acquéreur, des vices de construction ou des défauts de conformité alors apparents.” The seller must repair apparent defects reported within that window, and the action is fenced by a strict time limit: per Article 1648 of the Civil Code, “l’action doit être introduite, à peine de forclusion, dans l’année qui suit la date à laquelle le vendeur peut être déchargé des vices ou des défauts de conformité apparents.” Miss that year and the claim is foreclosed, whatever its merits. In the 2025 case cited above, the Court of Cassation quashed an appeal ruling that had rejected a buyer’s claim for finishing and remedial works on the ground that the defects should have appeared in the acceptance report with an itemised valuation, recalling that VEFA sales obey the 1642-1 and 1648 mechanism rather than the ordinary works-contract rules (Cass., 3rd civ., 13 Feb. 2025, no. 23-17.755). The lesson is operational: report every visible defect in writing within the month after taking possession, commission an independent expert report quickly, and file within the year even while settlement talks continue.
The second net is the ten-year liability, and it survives the developer’s disappearance. Article 1646-1 of the Civil Code makes the off-plan seller answerable as a builder, and its closing words protect the buyer on resale: “Ces garanties bénéficient aux propriétaires successifs de l’immeuble.” Backed by Article 1792 of the Civil Code, under which “Tout constructeur d’un ouvrage est responsable de plein droit, envers le maître ou l’acquéreur de l’ouvrage, des dommages, même résultant d’un vice du sol, qui compromettent la solidité de l’ouvrage ou qui, l’affectant dans l’un de ses éléments constitutifs ou l’un de ses éléments d’équipement, le rendent impropre à sa destination”, the buyer holds a strict-liability claim for serious damage for ten years from acceptance. Crucially, the two nets can overlap: the Court of Cassation has held that the buyer enjoys both the decennial action and the action for apparent defects, and that “il importe peu que le vice de construction ait été apparent à la date de la prise de possession par l’acquéreur” when the action is brought on the decennial foundation, because apparence is assessed in the person of the project owner at the date of acceptance of the works (Cass., 3rd civ., 14 Jan. 2021, no. 19-21.130). A crack visible when the keys were handed over is therefore not automatically lost to the one-year clock if it engages the ten-year liability. In insolvency cases this articulation is gold: the missing developer is replaced, on the decennial front, by its liability insurers, starting with the compulsory assurance dommages-ouvrage (construction-damage insurance) if one was subscribed and the decennial policies of the contractors, which the buyer can call upon directly.
In Paris and the Île-de-France, where off-plan programmes are dense and prices make every stage payment heavy, three local reflexes apply. First, venue: claims against the seller or guarantor for an Ile-de-France property are typically brought before the judicial court of the place where the building lies, and Paris-region courts handle a large volume of VEFA litigation, so procedural expectations on expert evidence and consignation are well settled but strictly applied. Second, timing: Paris buyers face the same statutory clocks as everywhere else, yet the practical delays of expert proceedings before the Paris courts mean the one-year foreclosure of Article 1648 must be secured by filing protectively rather than waiting for the expert’s final report. Third, paperwork: Paris programmes usually produce detailed stage certificates from the project supervisor and formal notices from institutional guarantors, so the absent foreign owner should centralise every notice from the administrator, the guarantor and the syndic (co-ownership manager) in a single chronological file shared with counsel. General background on how purchases and disputes are handled locally is available through a Paris real estate practice advising international clients on French property matters.
Conclusion
A developer’s insolvency does not erase an off-plan purchase; it activates the machinery French law built for exactly that event. The completion or refund guarantee takes over where the developer stopped, stage payments already made are capped and traceable, delay penalties run until the building is genuinely habitable, the balance can be consigned when conformity is disputed, and defects remain covered first by the one-year apparent-defects action and then by the ten-year strict liability that binds the seller as a builder. Each protection has a clock and a proof requirement, and the courts place the decisive burdens where they belong: on the guarantor to justify what it claims, and on the buyer to report and file in time. The foreign owner who keeps the full paper file, pays only what the statute allows, writes everything down and meets every deadline crosses the insolvency with the asset or the money, instead of with the loss.
