You bought a French company from abroad, the deal closed, the shares moved, and then the French bank froze the company’s account. Payroll is due, suppliers are calling, the online banking shows a block, and the branch tells your local manager it is waiting for head office compliance in Paris. Nothing in the share purchase agreement prepared you for this moment, because the freeze does not come from the seller, the notary, or the commercial court. It comes from the bank’s own legal duties, combined with a company file that no longer matches its new owner. This article explains, for a foreign founder or foreign group that has just taken over a French SAS (société par actions simplifiée, the flexible joint-stock company most foreigners use), a SARL (société à responsabilité limitée, the limited-liability company with stricter transfer rules), or a French subsidiary, why the freeze happened, what French law the bank is applying, and the exact sequence that gets the account working again. The general path from incorporation to Kbis (the official company identity extract issued by the greffe, the clerk of the commercial court) to VAT number and first hire is described in our guide to setting up a company in France as a foreign founder. This article takes over where that guide stops: the morning the money stops moving.
Three misunderstandings explain most panicked calls we receive. First, foreign buyers assume the seller’s banking relationship transfers with the shares. It does not transfer in any automatic sense: the bank reassesses the client because the client has new owners, new directors, and often a new pattern of incoming and outgoing wires. Second, buyers assume the INPI single counter filing (the Guichet unique, the online one-stop shop run by the INPI, the French intellectual-property and companies institute, through which all company registrations and updates pass since 2023) updates everything at once. It updates the public registers, but the bank runs its own parallel file and blocks first when the two files diverge. Third, buyers treat the freeze as a breach by the bank and threaten to sue immediately. Sometimes the bank has indeed broken the rules, and French courts do hold banks liable, but the fastest route to unblocking salaries is almost always a complete compliance file, not a writ. Read Part I to understand the bank’s legal position, then work through Part II as a checklist with your French counsel.
I. Why your French bank froze the account after the foreign takeover
A. How the bank justifies the freeze: ongoing identity checks and missing beneficial-owner papers
French banks operate under anti-money-laundering duties that apply before the relationship starts and for as long as it lasts. Before entering into a business relationship, the bank must identify the client and, where relevant, the beneficial owner, and verify those identities against written evidence: “Identifient leur client et, le cas échéant, le bénéficiaire effectif au sens de l’article L. 561-2-2” (they identify their client and, where applicable, the beneficial owner within the meaning of Article L. 561-2-2) and “Vérifient ces éléments d’identification sur présentation de tout document écrit à caractère probant” (they verify these identification details on presentation of any written document having probative value) (Article L. 561-5 of the Monetary and Financial Code). The beneficial owner, the person the bank is ultimately looking for behind the corporate layers, is defined by statute as “la ou les personnes physiques : 1° Soit qui contrôlent en dernier lieu, directement ou indirectement, le client” (the natural person or persons who ultimately control the client, directly or indirectly, or for whom a transaction is carried out or an activity is exercised) (Article L. 561-2-2 of the Monetary and Financial Code). In plain terms, after your takeover the bank must know which living individuals now stand at the top of the chain, with passports, addresses, and the precise percentage or control mechanism each holds. A share purchase agreement signed in London or Delaware, a foreign certificate of good standing, and the seller’s word that everything is in order do not satisfy this duty until the bank has collected and verified the documents itself.
The duty does not end at account opening. The same institutions must gather information on the purpose and nature of the relationship and keep it current: “recueillent les informations relatives à l’objet et à la nature de cette relation et tout autre élément d’information pertinent. Elles actualisent ces informations pendant toute la durée de la relation d’affaires” (they collect information on the purpose and nature of the relationship and any other relevant information, and they update this information throughout the business relationship) (Article L. 561-5-1 of the Monetary and Financial Code). Day to day, they must “exercent, dans la limite de leurs droits et obligations, une vigilance constante et pratiquent un examen attentif des opérations effectuées en veillant à ce qu’elles soient cohérentes avec la connaissance actualisée qu’elles ont de leur relation d’affaires” (exercise constant vigilance and scrutinize transactions closely, checking that they are consistent with their up-to-date knowledge of the business relationship) (Article L. 561-6 of the Monetary and Financial Code). A change of control is precisely the event that makes the bank’s knowledge obsolete: new shareholders, a new president of the SAS (président, the legal representative who binds the company), possibly a new pattern of cross-border transfers to repay the acquisition loan or to sweep cash to the foreign parent. The compliance software flags the mismatch, the file goes to a review team, and outgoing payments are suspended while the review runs. From the buyer’s side this looks like a freeze without warning. From the bank’s side it is the vigilance duty operating exactly as the statute describes.
Where the buyer comes from outside France, enhanced checks can apply on top of the standard ones. The statute requires additional vigilance measures, beyond the basic identification and updating duties, in several situations, including where “L’opération est une opération pour compte propre ou pour compte de tiers effectuée avec des personnes physiques ou morales, y compris leurs filiales ou établissements ou toute autre entité, domiciliées, enregistrées ou établies dans un Etat ou un territoire figurant sur les listes publiées par le Groupe d’action financière parmi ceux dont la législation ou les pratiques font obstacle à la lutte contre le blanchiment des capitaux et le financement du terrorisme” (the transaction is carried out, for own account or for third parties, with natural or legal persons, including their subsidiaries or establishments, domiciled, registered or established in a state or territory appearing on the lists published by the Financial Action Task Force of jurisdictions whose legislation or practices obstruct the fight against money laundering and terrorist financing) (Article L. 561-10 of the Monetary and Financial Code). Most American, British, or EU buyers will never trigger that high-risk-country logic, but groups with intermediate holding companies in listed jurisdictions, or with politically exposed persons among their ultimate owners, should expect a deeper questionnaire, source-of-funds evidence going back further, and a longer review. Even without any high-risk flag, the sanction for an incomplete file is blunt: where the bank cannot satisfy the identification and verification duties, “elle n’exécute aucune opération, quelles qu’en soient les modalités, n’établit ni ne poursuit aucune relation d’affaires” (it carries out no transaction, by any means, and neither establishes nor continues any business relationship), and where the relationship already exists under the deferred-verification exception, “elle y met un terme” (it terminates it) (Article L. 561-8 of the Monetary and Financial Code). That single sentence is the legal engine of most freezes: no verified owner, no movements.
Two practical consequences follow. First, arguing that the bank knows the company because it has banked it for ten years misses the point; the bank knew the former owners, and the statute obliges it to know the new ones with the same documentary rigor. Second, every week without the requested documents hardens the bank’s position, because the file shows a client that cannot be identified, and the statute pushes the bank from suspension toward termination. Sending partial answers, expired passports, or group charts without percentages keeps the file in the incomplete pile. The file that unfreezes accounts, detailed in Part II, mirrors the statutory list exactly: who owns, who controls, who signs, and where the money comes from.
B. What the takeover changed at the greffe and in the beneficial-owner register that the bank can see
While the bank reviews its own file, it also reads the public file, and after a takeover that file is usually out of date for several weeks. French companies declare their beneficial owners to the commercial court register (registre du commerce et des sociétés, the RCS, the official company register kept by the greffe), through the body designated for company formalities: “déclarent au registre du commerce et des sociétés, par l’intermédiaire de l’organisme mentionné au deuxième alinéa de l’article L. 123-33 du code de commerce, les informations relatives aux bénéficiaires effectifs” (they declare to the commercial and companies register, through the designated body, the information on beneficial owners), covering “les éléments d’identification et le domicile personnel de ces bénéficiaires ainsi que sur les modalités du contrôle que ces derniers exercent sur la société ou l’entité” (the identification details and home address of those beneficiaries and the means of control they exercise over the company or entity) (Article L. 561-46 of the Monetary and Financial Code). This filing is known in practice as the RBE declaration (registre des bénéficiaires effectifs, the beneficial-owner register). The implementing rule sets the pace: “La société ou l’entité immatriculée demande une inscription modificative dans les trente jours suivant tout fait ou acte rendant nécessaire la rectification ou le complément des informations déclarées” (the registered company or entity requests an amending entry within thirty days of any fact or act requiring correction or completion of the declared information) (Article R. 561-55 of the Monetary and Financial Code). A share sale that replaces the ultimate owners is exactly such an event: the thirty-day clock starts at closing, and the buyer, through the new directors, owns the filing duty.
Banks check this register as part of their review, because it is the only public source that names the living individuals behind the company. When the closing has just happened, three mismatches typically appear at once. The Kbis still shows the former president because the management update has not yet passed through the INPI single counter. The RBE extract still names the seller’s owners because the thirty-day update has not been filed. And the bank’s own signatory card still carries the seller’s officers, so the new president’s payment orders look, to the system, like orders from an unknown person. Each mismatch alone might trigger questions; together they look like a different company trying to operate an account it does not own, and the compliance team freezes first and asks afterwards. Foreign buyers who closed with a foreign-law purchase agreement and left the French filings to be handled later, by someone, someday, manufacture this exact situation.
The RBE duty has teeth that go beyond banking inconvenience. The president of the court, on his own motion or at the request of the public prosecutor or any interested person, “peut enjoindre, au besoin sous astreinte, à toute société ou entité juridique mentionnée au premier alinéa de l’article L. 561-46 de procéder ou faire procéder soit aux déclarations des informations relatives au bénéficiaire effectif, soit à la rectification de ces informations lorsqu’elles sont inexactes ou incomplètes” (may order, if necessary under penalty, any company or legal entity covered by Article L. 561-46 to file, or have filed, the beneficial-owner information, or to correct it where it is inaccurate or incomplete). Where the company ignores the order, “le greffier en avise le procureur de la République et lui adresse une expédition de la décision” (the clerk notifies the public prosecutor and sends a copy of the decision), and the president “Il peut procéder à la radiation d’office du registre du commerce et des sociétés de la société ou de l’entité, dans un délai de trois mois à compter de la notification de la décision” (may strike the company or entity off the commercial and companies register, within three months of notification of the decision) (Article L. 561-48 of the Monetary and Financial Code). The procedural mechanics confirm the seriousness: the order sets a deadline and any penalty rate, it is not open to appeal as such, and it is served by registered letter, with formal fallback to personal service where the letter goes unclaimed (Article R. 561-62 of the Monetary and Financial Code).
The Cour de cassation (the supreme court for civil, commercial, and criminal matters, whose commercial chamber hears company and banking appeals) has upheld this machinery twice in recent years, and both rulings deserve a place in any foreign buyer’s file. In the first, a company ordered to declare its beneficial owners challenged the penalty already partly enforced against it, and the commercial chamber restated the core rule that “le président du tribunal, d’office ou sur requête du procureur de la République ou de toute personne justifiant y avoir intérêt, peut enjoindre, au besoin sous astreinte, à toute société ou entité juridique mentionnée au premier alinéa de l’article L. 561-46 du même code de procéder ou faire procéder, soit aux déclarations des informations relatives au bénéficiaire effectif, soit à la rectification de ces informations lorsqu’elles sont inexactes ou incomplètes” (the president of the court, on his own motion or at the request of the public prosecutor or any interested person, may order, if necessary under penalty, any covered company to file or correct its beneficial-owner information), holding that the limited avenues of challenge, combined with the anti-money-laundering purpose, keep the procedure compatible with the right of access to a court (Cass. com., 18 September 2024, appeal no. 22-20.771, ECLI:FR:CCASS:2024:CO00477) (Cour de cassation, commercial chamber, 18 September 2024, no. 22-20.771). In the second, the same chamber rejected a company’s challenge to an order that had required it to file within one month of notification under a penalty of one hundred euros per day of delay, confirming that a company which claims it had already filed must prove it through the proper challenge route rather than ignoring the order (Cass. com., 17 December 2025, appeal no. 24-22.646) (Cour de cassation, commercial chamber, 17 December 2025, no. 24-22.646). For a foreign buyer, the message is direct: an RBE file left un-updated after closing can produce a court order with a daily penalty and, in the extreme, removal from the register, and the bank watching the same register will have frozen the account long before the judge acts.
II. How to unfreeze the account and secure the company from abroad
A. What to send the bank this week: the file that gets frozen accounts moving again
Treat the unfreeze request as a formal compliance submission, not as a phone negotiation. Banks process files, and the complete file jumps the queue while the incomplete one sits. Your French counsel should send one dated bundle, in French or with certified French translations, to the branch and to the compliance or KYC (know-your-customer) contact the branch designates, keeping proof of every transmission. The bundle has five parts. First, the new ownership chain: the executed share transfer documents, a group chart showing every layer from the French company up to the ultimate living individuals with exact percentages and voting rights, and for each ultimate owner a valid passport, proof of home address dated within three months, and, where the owner is itself a foreign company, its incorporation certificate with a recent extract from its home register plus a French translation. Second, the new management: the shareholders’ minutes appointing the new president (and any directeur général, the deputy executive the SAS may appoint), each officer’s passport and address proof, specimen signatures, and the updated signatory list with transaction limits. Third, the updated public papers: the draft or filed INPI single-counter receipts for the management change and the RBE update, then the fresh Kbis as soon as it issues, so the bank sees the public file converging with its own. Fourth, the economic purpose: a one-page note explaining what the French company does, where its clients and suppliers sit, the expected monthly volumes in and out, and why the first post-closing transfers (acquisition loan repayment, cash sweep, capital injection) look the way they do, with the underlying loan or cash-pooling agreements attached. Fifth, the source of funds for the purchase price: bank statements, loan offer, or capital-increase papers showing where the money came from. This bundle answers, line by line, the identification, purpose, updating, and vigilance duties of Articles L. 561-5, L. 561-5-1, and L. 561-6, and it leaves the reviewer no missing-document reason to keep the block.
Alongside the bundle, manage the human channel. Ask the bank in writing for three things: the exhaustive list of missing documents it still requires, the name and email of the officer handling the review, and a realistic decision date. Confirm in the same letter that salaries, social-security contributions to URSSAF (the unions for collection of social-security contributions, the body that collects employer and employee charges), and tax payments are time-sensitive and ask for a partial release limited to those priority payments pending full review. Banks sometimes agree to release payroll alone against a signed instruction and a payroll journal, even while the broader freeze continues. Keep every employee, supplier, and tax-deadline consequence in writing, because if the freeze later proves wrongful, the paper trail of warned consequences supports the damages claim. Do not instruct the new president to force payments through by unusual channels, split transfers across personal accounts, or route company money through the foreign parent’s account without documentation; unusual flows during a vigilance review deepen suspicion and can generate the very reports the buyer fears.
Know the bank’s counterpart duties, because the freeze is not a blank check for the bank either. Where the account package includes an overdraft or credit facility of indefinite duration, the statute provides that “Tout concours à durée indéterminée, autre qu’occasionnel, qu’un établissement de crédit ou une société de financement consent à une entreprise, ne peut être réduit ou interrompu que sur notification écrite et à l’expiration d’un délai de préavis fixé lors de l’octroi du concours. Ce délai ne peut, sous peine de nullité de la rupture du concours, être inférieur à soixante jours” (any indefinite-term credit facility, other than occasional, granted by a credit institution to a business may only be reduced or interrupted upon written notice and after a notice period set when the facility was granted, which may not, on pain of nullity of the termination, be less than sixty days) (Article L. 313-12 of the Monetary and Financial Code). The Cour de cassation has added that “l’entreprise qui subit la réduction ou l’interruption d’un concours bancaire peut, même après l’expiration du délai de préavis, en demander les raisons à la banque et qu’à défaut de réponse, la banque est susceptible de voir sa responsabilité engagée” (a business subjected to the reduction or interruption of a banking facility may, even after the notice period has expired, ask the bank for its reasons, and failing an answer the bank may incur liability) (Cass. com., 30 November 2022, appeal no. 21-17.703) (Cour de cassation, commercial chamber, 30 November 2022, no. 21-17.703). In practice, this means the bank that cuts an overdraft overnight without the written sixty-day notice, or that refuses ever to explain the cut, exposes itself to damages, and your counsel should invoke the text expressly. The pure deposit account without any credit line follows the account agreement’s own termination notice instead, which is why counsel must read the convention de compte (the written account agreement) before writing the demand letter. Either way, the demand letter should set a firm deadline, list the daily losses (late salary penalties, URSSAF surcharges, supplier termination clauses), and reserve all rights, because French judges quantify banking-liability damages from documented, foreseeable loss, not from general complaint.
B. What to fix at the INPI single counter and what to do if the bank still says no
Run the public-file repair in parallel with the bank submission, because the bank checks the registers before lifting anything. Three filings matter. First, the management update: appointment and resignation minutes, updated articles (statuts, the company’s constitutional document) where the president is named in them, and the identity papers of the new officers go through the INPI Guichet unique, which forwards to the competent greffe. Until the fresh Kbis shows the new president, every payment order the new president signs looks anomalous to the bank. Second, the RBE update within the thirty-day window of Article R. 561-55, naming the new ultimate owners with home addresses and control mechanics, because the bank compares its KYC chart against this register and treats divergence as a red flag. Third, where the takeover changed the registered office (siège social, the legal domicile that determines the competent court), the share capital, or the corporate name, file those updates in the same wave rather than spreading them over months; each staggered change restarts a verification cycle at the bank. Foreign documents need apostille (the Hague Convention authentication stamp) or legalization depending on the issuing country, plus sworn French translations, so start that work the day the deal signs rather than the day the account freezes. Keep every INPI filing receipt, because the bank’s compliance team accepts dated receipts as interim proof while the greffe processes the entries.
If the bank, once fully documented, still refuses to operate the account or announces it is closing it, French law offers two distinct exits, and counsel must pick the right one. The first is the statutory right to an account: “A droit à l’ouverture d’un compte de dépôt dans l’établissement de crédit de son choix, sous réserve d’être dépourvu d’un tel compte en France : 1° Toute personne physique ou morale domiciliée en France” (any natural or legal person domiciled in France, provided it holds no such account in France, is entitled to the opening of a deposit account with the credit institution of its choice) (Article L. 312-1 of the Monetary and Financial Code). The procedure requires a written refusal certificate (attestation de refus) from the bank, followed by referral to the Banque de France (the French central bank), which designates an institution that must open the account. Readers comfortable in French can also consult our French-language analysis of refusal and closure of a company account, including the free-closure rule in force since 28 May 2026. The official Banque de France and service-public.fr pages describe the current forms, counters, and time limits, and your counsel should follow them literally rather than relying on summaries. This route guarantees a basic deposit account with essential services; it does not guarantee overdrafts, foreign-currency lines, or the premium online tools the group treasury wants. It is a survival account, and it works: salaries and taxes can flow while the group negotiates a full-service relationship elsewhere.
The second exit is commercial: open a parallel account at a second bank before you need it. Sophisticated foreign groups run two French banking relationships precisely so that one compliance review never paralyzes the company. Nothing in French law requires a company to bank with a single institution, and the thirty-day RBE discipline plus a standing compliance file (updated group chart, officer papers, Kbis less than three months old, RBE extract) makes the second onboarding fast. Where the first bank’s freeze caused documented loss, counsel can pursue liability for abrupt credit rupture under Article L. 313-12, for breach of the account agreement’s notice clause, or on general fault grounds where the bank blocked funds without legal basis and against its own file. Courts assess these claims document by document: the complete KYC bundle sent on a dated letter, the bank’s silence or shifting explanations, the payroll journals, the URSSAF penalty notices, the lost contracts. The claim is the backup plan, not the rescue plan; file it while the new account pays the salaries.
A final word on timing for the foreign board. Count thirty days from closing for the RBE update, sixty days minimum notice for any indefinite credit the bank wishes to withdraw, and one business day for the Banque de France designation step once a complete refusal file reaches it. Align the deal timetable with these clocks: have the sworn translations, apostilles, and officer papers ready at signing, file the INPI updates in the first week, send the bank bundle the same week, and diary the response dates. The groups that suffer are not those whose business is suspicious; they are those whose papers arrive in dribs and drabs while the payroll clock runs. A takeover that updates the registers and the bank in the first ten days reads, to every reviewer, as a transparent change of owner. The same takeover with silent registers and surprise wires reads as a risk, and French law tells the bank exactly what to do with risks.
Conclusion
A frozen account after a foreign takeover is rarely a hostile act and almost always a compliance reflex: the bank must identify the new owners, verify them against documents, keep the file current, and suspend movements while it cannot. The foreign buyer controls the three levers that release the block: a complete KYC bundle that mirrors the statutory checklist, an RBE and Kbis file updated within the thirty-day window so the public registers confirm the private file, and a written, deadline-driven dialogue with the bank that preserves the liability claim if the freeze proves wrongful. Behind those levers sit hard rules with court-tested penalties: daily fines for ignored beneficial-owner orders, possible removal from the company register, sixty days minimum notice before an indefinite credit line dies, and damages where the bank will not explain itself. Treat the first month after closing as a regulatory project with the same seriousness as the acquisition itself, run the bank file and the INPI filings in the same week, and keep a second banking relationship warm. Handled that way, the freeze becomes a two-week administrative episode. Handled late, it becomes salary arrears, URSSAF penalties, supplier terminations, and a damages action that pays for the losses long after the trust is gone.
