The compromis de vente (preliminary sale agreement) is the document that truly commits you when you buy property in France. Many foreign buyers treat it as a reservation form and focus all their attention on the final signing before the notaire (public conveyancing officer). That is a mistake. Once the withdrawal period expires and the conditions precedent are worded badly, you can lose your deposit, face a penalty worth ten percent of the price, or be forced to complete a purchase your bank will not finance. This guide walks through the two stages that matter most: signing safely with the ten-day withdrawal right, and reaching the final deed through the loan condition and the technical diagnostics file.
I. Signing the compromis safely and using the ten-day withdrawal period
A. What the compromis is, and what happens to the money you pay at signing
A compromis de vente is normally a synallagmatic promise: both parties bind themselves, the seller to sell and the buyer to buy, and the agreement is in substance already the sale, subject only to the conditions it contains. It must be distinguished from the promesse unilatérale de vente (unilateral promise of sale), in which only the seller is bound for an option period while the buyer pays an indemnité d’immobilisation (option fee, commonly ten percent) that he loses if he walks away. Foreign buyers sometimes sign one thinking it is the other. Before initialling anything, identify which instrument you are signing, because the consequences of withdrawal are entirely different.
At the compromis stage the buyer usually pays a deposit of five to ten percent of the price. That sum is not handed to the seller. It is placed under séquestre (escrow), most often in the notaire’s escrow account, and it is applied against the price on completion. If the sale collapses because a condition precedent fails, the escrowed sum must be returned. If the buyer simply refuses to complete after the withdrawal period and without a valid condition, the seller can claim the contractual penalty and, in some cases, seek forced performance of the sale. The exact outcome depends on how the penalty clause, the deposit clause and the conditions were drafted, which is why the wording reviewed below deserves more attention than the glossy property description.
French law protects the non-professional buyer of residential property with a mandatory withdrawal right. Article L. 271-1 of the Construction and Housing Code provides that “l’acquéreur non professionnel peut se rétracter dans un délai de dix jours à compter du lendemain de la première présentation de la lettre lui notifiant l’acte”, which means that a non-professional buyer may withdraw within ten days starting the day after the first presentation of the letter notifying him of the agreement. This is a matter of public policy in residential conveyancing, and the compromis itself must state the withdrawal terms in readable and understandable form. A missing or defective information notice exposes the professional involved to an administrative fine of up to 3,000 EUR for an individual and 15,000 EUR for a legal entity.
The courts apply the notification rules strictly, and they do so in both directions. In a ruling of 9 July 2020, the Third Civil Chamber of the Court of Cassation censured a court of appeal that had added a requirement the statute does not contain when assessing whether the notification of a synallagmatic promise of sale was regular: Cass. 3rd civ., 9 July 2020, No. 19-18.943, “la cour d’appel qui a ajouté à l’exigence légale de notification de l’acte une condition qu’elle ne comporte pas, a violé le texte susvisé”, meaning that a lower court which adds to the statutory notification requirement a condition it does not contain violates the governing provision. For a foreign buyer, the practical lesson is symmetrical: you cannot invent extra formalities to escape a compromis you regret, and the seller cannot invent extra formalities to defeat your withdrawal. Only the statutory mechanism counts, so read it before you need it.
Notification mechanics matter enormously when you sign from abroad. The agreement is notified by registered letter with acknowledgment of receipt, or by any other means offering equivalent guarantees for establishing the date of receipt or delivery. Where a professional instructed to assist with the sale acts as intermediary, the document may be handed over directly, with the withdrawal period running from the day after delivery under conditions set by decree. A buyer who gives a holiday address, returns to London or New York the day after signing, and never collects the letter gains nothing. The Court of Cassation has held, under the earlier seven-day version of the same provision, that a buyer who had been duly notified but simply failed to collect his registered letter at the post office could not escape the running of the period: Cass. 1st civ., 14 February 2018, No. 17-10.514, “pour tout acte ayant pour objet l’acquisition d’un immeuble d’habitation, l’acquéreur non professionnel peut se rétracter dans un délai de sept jours à compter du lendemain de la première présentation de la lettre lui notifiant l’acte”, which states the rule that the withdrawal period runs from the day after the first presentation of the notifying letter. In that case the seller’s penalty claim against the buyers had already been finally rejected, and the dispute had moved to the seller’s damages claim against the notaire over the allegedly missing notification; the Court quashed the appeal ruling. The message for buyers is blunt: organise your mail, your forwarding address and your calendar around the notification date, because the clock runs whether or not you open the envelope.
Three practical checks follow from this case law. First, confirm in writing how and to which address the compromis will be notified, especially if you are only passing through Paris for the viewing and the signing. Second, if both spouses or partners are buying, make sure each of them is duly notified, since each buyer holds his own withdrawal right. Third, keep proof of everything: the signed agreement, the notification letter, the acknowledgment of receipt or delivery certificate, and any withdrawal letter you send. A withdrawal sent by the wrong means or one day late is worthless, and the dispute will turn on documents, not on what the agent remembers saying on the telephone.
B. Exercising the withdrawal right: ten days, the right form, and the traps for buyers signing from abroad
The ten-day period is counted from the day after the first presentation of the notification letter, and the withdrawal itself must be exercised in the same forms, meaning registered letter with acknowledgment of receipt or equivalent means. Count calendar days, not working days, and do not assume that a weekend or a public holiday pauses the clock. If the tenth day is the problem, send earlier rather than later, because the only date that matters is the one you can prove. A buyer who telephones the agent to say the deal is off, then posts the letter a week later, has not withdrawn within the period.
Foreign buyers face four recurring traps at this stage. The first is the flying visit: you sign on a Friday afternoon in the agent’s office, fly home on Saturday, and the notification letter arrives at an address where nobody collects it. The period still runs. Give the notaire a reliable address and, where the rules allow, agree on a notification method whose receipt you can monitor from abroad. The second trap is the professional-status question. The protection is reserved to the non-professional buyer of residential property. Most private individuals buying a flat or a house qualify, but if you buy through a company structure or in the course of a professional activity, have your status analysed before signature rather than after a dispute arises. The third trap is the direct final deed. Where no preliminary contract precedes the acte authentique (notarial deed of sale) drawn up in authentic form, the buyer instead benefits from a ten-day reflection period running from notification or delivery of the draft deed, and the deed cannot be signed during that period. Off-plan and hurried transactions sometimes take this route, and buyers who expected a withdrawal right discover a differently shaped protection. The fourth trap is language. The withdrawal notice reproduced in the compromis is written in French legal terms. Machine translation on the day of signature is no substitute for understanding, before you sign, which day the clock starts and which form your withdrawal must take.
Use the withdrawal period for what it is: a final verification window, not an excuse for careless signing. In those ten days, have the title documents, the co-ownership information, the diagnostics and the financing plan reviewed. Buyers assisted by real estate lawyers in Paris routinely use this window to order the searches and readings that the excitement of the viewing had postponed. If the file is clean, you let the period expire and move toward completion with confidence. If it is not, a timely withdrawal costs you nothing and returns the escrowed deposit. What you must never do is treat the period as renegotiation time: attempting to force the price down under threat of withdrawal can backfire, and any amendment should be put in writing through the notaire with a clear effect on the running periods.
II. Loan conditions, diagnostics and the road to the final deed
A. The mortgage condition and the diagnostics file: your two lawful exit routes
After the withdrawal period, the buyer’s principal protection is the condition suspensive (condition precedent), and the most important of them is the mortgage condition. Article L. 313-41 of the Consumer Code imposes it automatically whenever the compromis states that the price is paid, even partly, with loans falling under the regulated consumer-credit regime: the agreement is then concluded under the condition precedent of obtaining the financing loans, the condition must remain valid for at least one month from signature, and “Lorsque la condition suspensive prévue au premier alinéa n’est pas réalisée, toute somme versée d’avance par l’acquéreur à l’autre partie ou pour le compte de cette dernière est immédiatement et intégralement remboursable sans retenue ni indemnité à quelque titre que ce soit”, which means that where the loan condition fails, every sum paid in advance by the buyer must be refunded immediately and in full, with no deduction or indemnity of any kind. This refund rule is why the precise drafting of the loan clause matters so much: amount, maximum rate, maximum duration and deadline for producing refusals.
The general law of conditions reinforces the point. Article 1304 of the Civil Code defines the mechanism: “La condition est suspensive lorsque son accomplissement rend l’obligation pure et simple”, meaning that a suspensive condition is one whose fulfilment turns the obligation into a straightforward one. As long as the condition is pending, neither party can demand performance; once it fails definitively, the sale lapses and the deposit comes back. But the buyer must play his part honestly. Article 1304-3 of the Civil Code provides that “La condition suspensive est réputée accomplie si celui qui y avait intérêt en a empêché l’accomplissement”, which means that a suspensive condition is deemed fulfilled where the party interested in it prevented its fulfilment. A buyer who files no application, files a deliberately incomplete one, or applies for a different amount than the compromis stipulates cannot then rely on the loan refusal to walk away with his deposit.
The Court of Cassation polices this balance closely. In a 2019 ruling, the Third Civil Chamber quashed an appeal decision that had ordered buyers to complete without examining whether they had applied for financing in the contractual forms and time limits and been refused, and whether the failure of the condition had rendered the contract void: Cass. 3rd civ., 18 April 2019, No. 16-17.984, “sans rechercher, comme il le lui était demandé, si M. S… n’avait pas, dans les formes et délais prévus au contrat, sollicité un financement qui lui avait été refusé et si la défaillance de la condition suspensive n’avait pas entraîné la caducité du contrat, la cour d’appel n’a pas donné de base légale à sa décision”, which means the lower court failed to give its decision a legal basis by not investigating whether the buyer had sought financing as the contract required, been refused, and thereby caused the contract to lapse. Translate this into a checklist: apply to at least the number, amount and type of loans specified in the compromis, within the contractual deadline, keep every refusal letter and every acknowledgment of receipt, and notify the seller of the failure in the stipulated form and time. Non-resident buyers should add a margin for the slower processing of cross-border files, and should never accept a clause reducing the condition to a token duration under pressure from a Paris seller who claims to have three backup offers. If you pay cash and strike out the loan condition, understand that you are giving up your main exit route: a financing difficulty discovered later will not release you.
The second lawful exit route runs through the technical diagnostics file. Article L. 271-4 of the Construction and Housing Code requires the seller to attach to the promise of sale, or failing that to the final deed, a file containing the lead, asbestos, termites, gas, electricity, energy performance, risk and sanitation statements applicable to the property. This file is not decorative paper. It allocates risk between seller and buyer, and its defects or its obsolescence at the date of the final deed can support resolution of the sale or a price reduction.
Recent case law shows how seriously the courts take the updating duty. On 19 February 2026 the Third Civil Chamber held that where, after the promise of sale, the plot becomes covered by a prescribed or approved foreseeable natural-risk prevention plan, the diagnostics file must be completed at the signing of the final deed with a risk statement or an update, failing which the buyer may seek resolution or a price reduction; and that where a plan mentioned as merely prescribed at the promise stage has been approved before the final deed, the file must be updated to reflect the approved plan, which operates as a public-utility easement: Cass. 3rd civ., 19 February 2026, No. 24-10.524, “si, après la promesse de vente faisant état d’un plan de prévention des risques naturels prévisibles prescrit, celui-ci a été approuvé avant la signature de l’acte authentique, le dossier de diagnostic technique doit être complété par une mise à jour de l’état des risques”, which means that the technical diagnostics file must be updated where the risk plan moved from prescribed to approved between the promise and the deed. An earlier ruling on the same theme had already opened this path for buyers where the risk disclosure attached to the promise no longer matched the position at completion: Cass. 3rd civ., 19 September 2019, No. 18-16.700. For a foreign buyer this matters in practical terms along the Seine flood plain, in clay subsidence zones around Paris, and in mountain and coastal areas: always compare the état des risques (natural and technological risk statement) attached to the compromis with a fresh statement before the final deed, and have any newly approved plan explained in plain language before you sign.
Energy performance deserves a separate warning. In a 2019 decision the Court of Cassation held that, unlike the other documents in the diagnostics file, the energy performance diagnostic had only informative value: Cass. 3rd civ., 21 November 2019, No. 18-23.251. That ruling belongs to the legal landscape of its time, and buyers should ask their notaire which evidentiary value the current energy performance rules give the diagnostic at the date of their own transaction, particularly for older Parisian stock where the rating drives both renovation obligations and rental restrictions. Whatever the precise regime, the commercial lesson is stable: a poor energy rating is a cost forecast. Obtain quotes for the works the rating implies, check them against the financing plan covered by the loan condition, and renegotiate or withdraw through the proper contractual channel rather than discovering the bill after completion.
B. Reaching the final deed with the notaire: checks, money and the Paris practicalities
The acte authentique is signed before the notaire, who acts as a neutral public officer rather than as any party’s advocate. Between the compromis and that appointment, the notaire verifies title over the statutory period, checks mortgages and charges, exercises or purges pre-emption rights, gathers co-ownership documents, and prepares the statement of funds. At the appointment the notaire reads the deed, collects the balance of the price plus taxes and fees, and registers the transfer. Foreign buyers sometimes arrive expecting a quick countersignature. Expect instead a long reading session, in French, in which every easement, charge and declaration is stated for the record. If your French is not fluent, arrange interpretation in advance and ask for the draft deed several days before the appointment so that nothing is discovered across the desk.
Three verifications deserve personal attention rather than blind trust in the machinery. First, the droit de préemption urbain (urban pre-emption right): in Paris the municipality or a delegated body can step into the buyer’s shoes within a fixed period after notification of the intended sale. Your notaire handles the purge, but the timetable affects your financing and your moving plans, so diarise it. Second, co-ownership: for a flat, the information on charges, planned works, arrears and the maintenance record determines the real cost of ownership far more than the headline price. Question any vague statement about future works and have major-project votes quantified. Third, occupancy and boundaries: confirm that the property will be free as promised, that the floor area and description match the title, and for houses that fences, extensions and outbuildings correspond to the registered position. Discrepancies found after the deed become your problem to solve through litigation rather than the seller’s problem to fix before payment.
Money mechanics cause more failed completions than legal disputes. The balance is transferred to the notaire’s escrow before signing, and international transfers take longer than domestic ones, with anti-money-laundering checks applied to large cross-border flows. Initiate the transfer early, confirm the exact euro amount including prorations of property tax and co-ownership charges, and keep a buffer for exchange-rate movement between the compromis and the deed. If you cannot attend in person, a procuration (power of attorney) executed before a notaire or under the formalities accepted for your country of residence allows representation at the signing; arrange it weeks ahead, not days, because defective powers are a classic cause of adjourned appointments. Bring valid identification, proof of matrimonial or partnership regime with a sworn translation where required, and the financing evidence the deed recites. Each missing paper postpones completion while interest, rate locks and removal bookings keep running.
Paris and the inner suburbs add their own layer. Competition pushes some buyers to waive the loan condition to make an offer attractive, which experienced advisers treat as the single most dangerous concession in the Paris market: it converts a financing hiccup into a forfeited deposit or worse. Pre-1949 Haussmann buildings concentrate lead, electrical and co-ownership-work issues, so read those diagnostics line by line. Flood-zone and clay-movement disclosures around the Seine corridor should be cross-checked against the fresh risk statement as explained above. And where the seller is a non-resident, the capital-gains and appointed-representative machinery can affect the timetable and the net price allocation at the deed, a point developed in our companion analyses of non-resident transactions. None of these points blocks a purchase; each of them rewards a buyer who scheduled verification time instead of compressing the compromis-to-deed interval to the minimum.
If the seller refuses to complete after a clean file, French law is not helpless: performance in kind can be sought, and the penalty clause is not the seller’s only exposure. Conversely, if you as buyer must default, do not simply disappear. A documented impossibility channelled through the contractual mechanisms, negotiated openly via the notaire before deadlines expire, almost always costs less than silence followed by litigation. The compromis is a binding contract between consenting adults, and French courts treat it that way; they enforce its conditions with equal rigour whether the disappointed party is French or foreign.
Conclusion
A French purchase stands or falls on the compromis, long before the ceremony of the final deed. Identify which promise you are signing and where the deposit sits. Calendar the ten-day withdrawal period from the first presentation of the notification and exercise it in the provable statutory form if the file disappoints. Draft the loan condition with amount, rate, duration and deadlines you can actually meet, file genuine applications on time, and keep every refusal. Compare the diagnostics attached to the promise with a fresh file before the final deed, particularly the risk statement where a prevention plan may have been approved in the meantime. Then let the notaire’s verification run its course, fund the escrow early, and arrive at the signing with complete papers or a valid power of attorney. Buyers who follow this sequence rarely need a courtroom; buyers who skip it often meet one.
