You signed a compromis de vente (preliminary sale agreement) for a flat in Paris, paid a 5 or 10 percent deposit into the notaire’s (notary’s) escrow account, and then your bank said no. For a foreign buyer — paid in dollars, pounds or dirhams, tax-resident abroad, borrowing from a French bank that barely knows your file — this is the most stressful moment of the purchase. The good news is that French law was built for exactly this situation: when the sale is signed under a condition suspensive (suspensive condition) of obtaining a mortgage, a genuine loan refusal normally cancels the sale and sends the escrowed money, the séquestre (escrow deposit), back to you. The bad news is that sellers and their lawyers know the three traps that let them keep it: a non-conforming application, a passive file, and a missed deadline. This guide explains, step by step and with the latest Court of Cassation rulings, how to build the proof file that gets your deposit back.

French readers call this document a compromis; foreign buyers sometimes sign a promesse unilatérale de vente (unilateral promise of sale) instead. The loan-proof rules below apply to both, with one difference explained in section II: under a unilateral promise, the money you lodged with the notaire may be characterised as an indemnité d’immobilisation (lock-in fee) rather than a simple deposit, and that changes what the seller can claim. Everything that follows reflects the law as it stands in September 2026, including a February 2026 ruling that every foreign buyer should read before answering the seller’s formal notice.

I. The loan condition: what French law requires from the buyer

A. A statutory safety net with a one-month minimum

When your purchase is even partly financed by a French-regulated home loan, the law writes the safety net into your contract for you. Article L. 313-41 of the Consumer Code provides that the deed is concluded under the suspensive condition of obtaining the loan or loans that finance it, and that the validity period of that condition cannot be less than one month from the signing date. In plain English: if the deed says you are borrowing, the sale legally depends on you actually getting the loan, and the seller must give you at least one month to get it. Most compromis drafted by Paris notaires give forty-five to sixty days, and you can negotiate longer — which a non-resident buyer, whose file needs translation, foreign tax returns and sometimes a représentant fiscal (fiscal representative) paper trail on the financing side, should systematically do.

The condition itself is defined by Article 1304 of the Civil Code: an obligation is conditional when it depends on a future and uncertain event, and the condition is suspensive when its fulfilment turns the obligation into a straightforward one. « L’obligation est conditionnelle lorsqu’elle dépend d’un événement futur et incertain. » Until the loan is granted, you owe nothing except honest effort; once it is granted, the sale becomes final. If the loan is definitively refused, the condition fails, each party walks away, and the escrowed deposit must be returned. Article 1304-6 of the Civil Code confirms the mechanics: the obligation becomes straightforward upon fulfilment of the suspensive condition, and symmetrically, its definitive failure releases both sides.

Three practical consequences follow for a foreign buyer. First, check that your compromis actually states that the price is paid with the help of one or more loans: without that mention, the statutory condition does not attach automatically, and you must rely on a contractually drafted clause instead. Second, read the loan specifications the deed imposes — amount, maximum rate, maximum duration, maximum monthly payment — because your applications must mirror them exactly, as section II explains. Third, calendar the expiry date of the condition the day you sign: everything — applications, refusals, the registered letter to the seller — must fit inside it, and any extension must be agreed in writing before it lapses. A buyer who lets the deadline pass without proof of refusal hands the seller the argument that the condition was never properly invoked.

One more protection exists for buyers of residential property who are not acting in a professional capacity: Article L. 271-1 of the Construction and Housing Code gives the non-professional buyer ten days to withdraw from the deed, counted from the day after the first presentation of the registered letter notifying it. « 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 » This ten-day cooling-off period runs before any loan question arises, and a buyer who withdraws in time recovers everything without having to prove anything about banks. Foreign buyers sometimes discover this right too late because the notification letter arrives at their address abroad; ask your notaire to notify you at an address where someone can sign for the letter, or to hand it to you directly against receipt, so the clock starts on a date you control.

B. Your duty: conforming applications, filed diligently and on time

The safety net is not a hammock. French courts consistently hold that a buyer who wants to rely on the failure of the loan condition must show that he actually applied, in good time, for a loan matching the specifications written in the deed. A buyer who applies for a different amount, at a different rate, over a different term, or who applies once, casually, the day before the deadline, will be treated as the author of his own misfortune — and the seller will claim the penalty clause.

The leading modern statement comes from the Third Civil Chamber of the Court of Cassation in a 1 April 2021 ruling on a sale signed under a condition of obtaining a 757,800 euro loan at a maximum rate of 2.30 percent over twenty-five years (Cass. 3rd civ., 1 Apr. 2021, No. 19-25.180). The sellers argued that the buyers’ application, filed at 1.80 percent, did not match the contract and that the penalty clause of 81,000 euros should apply. The Court rejected the sellers’ case on the facts, but it restated the rule clearly: the buyer must prove that he sought, in due time, financing that conforms to the contract’s criteria. Where the Court saved the buyers was on the evidence — the bank had written that a conforming application at 2.30 percent would have been refused as well, so the condition had failed through no fault of theirs. The lesson is double-edged and every foreign buyer should memorise both edges: a non-conforming application exposes you to the penalty, but a written bank statement that even a conforming file would have been rejected protects you.

The February 2026 ruling every buyer should now cite goes further in your favour (Cass. 3rd civ., 5 Feb. 2026, No. 23-21.386). Buyers of a 2.43 million euro estate had lodged funds with the notaire against a possible lock-in fee, were formally required within eight days to show whether the two-loan condition had been met or had failed, and did not answer — then, on appeal, produced two loan applications filed the same day with two banks, both refused, which the court of appeal found matched the contractual specifications. The seller objected that evidence produced for the first time on appeal, after ignoring the formal notice, could not count. The Court of Cassation disagreed: the deed set no time limit for producing the refusal evidence, so producing it in support of the restitution claim, even on appeal, was perfectly valid, and buyers who were not responsible for the condition’s failure had to recover the funds lodged with the notaire. In short, a late-organised proof file still wins — provided the applications themselves were filed in time and matched the contract.

The mirror image is the bad-faith buyer. Article 1304-3 of the Civil Code states that a suspensive condition is deemed fulfilled where the party who had an interest in it prevented its fulfilment. « La condition suspensive est réputée accomplie si celui qui y avait intérêt en a empêché l’accomplissement. » Standard Paris deeds spell this out: if the loans were not obtained because of the buyer’s fault, negligence, passivity or bad faith, the seller can ask the court to declare the loan condition fulfilled — meaning the sale goes ahead or the penalty falls due. For a foreign buyer, the danger zone is concrete: applying to a single bank known to refuse non-residents while ignoring mainstream lenders, submitting an incomplete file and never completing it, refusing a loan offer that matches the contractual terms, or letting the condition expire without asking for an extension. Any of these can be framed as passivity or bad faith. The antidote is equally concrete and forms the checklist in section II: at least two complete applications to established lenders, filed within days of signing, matching the deed to the euro and the decimal point, chased in writing, with every refusal kept in its original form.

II. Getting the escrow back: the proof file, the deadlines and the traps

A. The exact proof file that recovers the deposit

When the refusals arrive, do not telephone the seller in a panic and do not sign anything the estate agent slides across the table. Work through the following file methodically; it is the file the courts expect, and it is the file that won the February 2026 case above.

First, the applications. File at least two complete applications with established banks or recognised brokers within the first two weeks after signing, and make each one conform exactly to the deed: same amount, same maximum rate, same duration, same ceiling on monthly payments. A non-resident application is heavier than a domestic one — translated pay slips, foreign tax assessments, proof of the deposit’s origin for anti-money-laundering checks, sometimes a French bank account opened specially — so start collecting these documents before you sign the compromis, not after. Keep dated proof of every filing: the bank’s acknowledgement of receipt, the online submission confirmations, the broker’s mandates. If the deed requires applications to several banks, or sets a deadline for filing them, treat that deadline as sacred; missing it is the single most common reason restitution claims fail.

Second, the refusals. You need written refusals, not oral ones. A bank advisor telling you on the telephone that “it will not pass” is worth nothing in court; a signed refusal letter on the bank’s letterhead, or at minimum a written message from an identified advisor stating the refusal, is everything. Chase each refusal in writing and keep the full thread. If a refusal is vague, ask the bank to confirm in one sentence that the application, as filed, was refused — you do not need the bank’s internal reasons, and banks rarely give them. The decisive extra, taught by the 2021 ruling, is a sentence from the bank confirming that an application matching the contractual terms would have been refused as well. You will not always obtain it, and the February 2026 ruling shows it is not indispensable where your applications already conformed, but where your application deviated even slightly — a lower rate requested, a shorter term — that one sentence neutralises the seller’s entire “non-conforming application” argument. Ask for it politely and in writing; some banks provide it, and when they do, keep the original.

Third, the notification. The standard deed requires you to inform the seller — in practice the notaire — of the outcome before the condition’s expiry, and authorises the seller to send you a mise en demeure (formal notice) demanding proof within about eight days. Answer every formal notice by registered letter with acknowledgement of receipt, inside the deadline, enclosing copies of the conforming applications and the written refusals, and stating expressly that the suspensive condition of obtaining the loans has failed through no fault of yours and that you request restitution of the escrowed funds. Even if you missed the eight-day deadline, the February 2026 ruling confirms that the underlying evidence can still be produced later, including on appeal — but never rely on that indulgence voluntarily, because meanwhile the seller may instruct the notaire to freeze the funds and you will spend months recovering them. Send the letter as soon as the last refusal arrives, and in any event before the condition expires.

Fourth, the release. In the standard case the notaire returns the séquestre once both parties agree that the condition failed, which is the usual outcome when the proof file is complete. If the seller disputes it, the notaire — who is neutral and cannot judge the dispute — keeps the funds until the parties agree or a court decides. Your leverage is then a clean, dated file: conforming applications, written refusals, timely registered letters. Most sellers settle at this stage rather than litigate against the 2021 and 2026 case law. If they do not, your claim is an action for restitution of the deposit founded on the failure of the condition, brought before the judicial court of the property’s location, with interest running from the formal demand. Foreign buyers living abroad can instruct a Paris lawyer without travelling: procedure is written, and a notaire’s file plus bank letters is the rare dispute that can be conducted almost entirely on paper. For an overview of how our firm assists international buyers at every stage of a French purchase, see our Paris real estate law practice.

A final practical point on financing strategy. Non-resident files are refused more often than domestic ones, and a refusal after a thin file helps nobody. Before signing, ask your broker which lenders actually process non-resident applications at your profile and amount, and whether a French branch of an international bank or a specialised broker would treat your foreign income more fairly. Two serious applications to lenders that genuinely handle non-resident files are worth more than five speculative ones. And never accept, after a refusal, a “replacement” loan at terms materially worse than the deed’s specifications and then abandon it: the seller will argue you refused conforming finance. If the only offers available breach the contractual ceilings on rate or monthly payments, that is itself evidence the condition failed — but say so in writing, with figures, at the time.

B. The three traps that forfeit the deposit

The first trap is bad faith, and it is the one sellers plead most aggressively. Remember Article 1304-3: a buyer who prevents the condition’s fulfilment is treated as if it had been fulfilled. Courts apply this to buyers who never seriously applied, who sabotaged their own file, or who refused a conforming offer to escape a purchase they regretted. The 2021 decision shows the boundary precisely: the buyers survived because the bank’s letter proved a conforming application would also have failed. Without that letter, a materially non-conforming application leaves you exposed to the full penalty clause — 81,000 euros in that case. For a foreign buyer the risk has a specific shape: instructing a broker to apply only to lenders with no non-resident desk, then brandishing their refusals, looks like manufactured failure. Apply where genuine finance was plausibly available, document it, and keep the broker’s written advice on lender selection.

The second trap is the calendar. Two different clocks run at once and buyers confuse them. The ten-day withdrawal right under Article L. 271-1 runs from the day after first presentation of the notification letter, and a December 2024 ruling of the Third Civil Chamber clarifies its computation: the starting day is excluded and the ten-day rule does not combine with the general procedural counting rule to add an extra day (Cass. 3rd civ., 19 Dec. 2024, No. 23-12.652). Miss it by one day and the withdrawal is ineffective — the buyer in that case paid 3,500 euros in damages to the agent for refusing to complete. Separately, the loan condition’s own expiry date governs the deposit: let it pass without notifying the refusals or obtaining a written extension, and the seller will argue the sale became final. Diary both dates on signature day, add reminders a week before each, and never assume a verbal extension from the agent binds the seller. Only a written amendment signed by both parties moves the deadline.

The third trap is the nature of the money itself. Under a compromis (a bilateral promise, governed as an ordinary conditional contract under Article 1304), the deposit is straightforwardly refundable when the condition fails without your fault. Under a unilateral promise of sale, governed by Article 1124 of the Civil Code, the sum lodged with the notaire may be an indemnité d’immobilisation — and a January 2025 ruling holds that this fee, where it genuinely prices the exclusivity granted to the buyer, is not a clause pénale (penalty clause) and cannot be reduced by the judge (Cass. 3rd civ., 16 Jan. 2025, No. 23-23.378). « ne sanctionnant pas une inexécution contractuelle mais représentant le prix de l’exclusivité accordée aux bénéficiaires, celle-ci, qui ne constituait pas une clause pénale, ne pouvait être réduite par le juge. » In that case the buyers lost 80,000 euros plus damages because they simply failed to complete in time: no failed loan condition, no timely withdrawal, just a late change of mind. Know which instrument you signed before strategising. And note the asymmetry that follows: a penalty clause, where one exists, can be moderated by the judge if it is manifestly excessive, since Article 1231-5 of the Civil Code allows the court to reduce a penalty that is clearly disproportionate — but the lock-in fee under a unilateral promise enjoys no such reduction. This is why the proof file matters so much more under a unilateral promise: your only safe exit is demonstrating that the loan condition failed without your fault, exactly as the buyers did in February 2026.

Foreign buyers face one last, quieter trap: language and distance. Refusal letters in English from a foreign bank do not satisfy a condition drafted around French-regulated loans; notifications sent by email when the deed requires registered letters do not stop the clock; and powers of attorney given informally to a friend in Paris do not authorise anyone to extend your condition. Have the deed’s key clauses — loan specifications, notification method, expiry date, characterisation of the deposit — translated before you sign, and route all correspondence through your notaire or lawyer from the first refusal. The cost of an hour of advice at signature stage is trivial beside a frozen deposit of tens of thousands of euros. Our Paris team advising foreign buyers reviews compromis clauses and refusal files before positions harden.

Conclusion

A refused mortgage in France is a procedural problem with a procedural solution, not the loss of your deposit. The statute gives you at least one month and makes the sale conditional on finance; the courts require from you, in return, conforming applications filed diligently, written refusals, and timely notice. Build that file from the day you sign — two conforming applications to lenders that genuinely handle non-resident profiles, every step dated and written, refusals chased until they are on letterhead, the seller notified by registered letter before the condition expires — and a refusal ends the sale with your escrow returned. Neglect it, manufacture it, or confuse the two deadlines, and the same law hands the seller the penalty: a condition deemed fulfilled under Article 1304-3, a late withdrawal declared ineffective, or a lock-in fee the judge has no power to reduce. The February 2026 ruling is reassuring but should not make anyone casual: late evidence can still save a genuine file, as those buyers proved, yet nothing saves a file that was never genuine. Sign carefully, apply seriously, notify in writing, and keep every page.
