A foreign buyer can appear to have a signed deal, a negotiated price and a complete closing file, yet still lose a share transfer in a French SAS (société par actions simplifiée, a flexible French joint-stock company) because the company’s articles of association contain a statutory pre-emption clause. The decisive question is not always whether the buyer knew about the clause or acted fraudulently. A major ruling of the French Supreme Court, Commercial Chamber, on 8 July 2026, no. 25-11.354, confirms that a transfer made in breach of a statutory pre-emption right can be annulled without proving collusion between the seller and the buyer.

This distinction matters in cross-border transactions. A foreign founder, a foreign parent company or an international investment fund may review the share purchase agreement, the corporate approvals and the French company register, yet overlook the exact mechanics of the articles. The risk is particularly high where the transaction is conducted through powers of attorney, translated documents, a Luxembourg or other non-French buyer, or a closing timetable driven by a foreign group. This guide explains what the rule means, how to distinguish the articles from a private shareholders’ agreement, which documents and notices must be checked, and how a buyer or shareholder should react before the dispute becomes irreversible.

I. Can a French SAS block a foreign buyer before completion?

A. How the statutory pre-emption clause changes the transaction

A pre-emption clause is not simply a courtesy notice to existing shareholders. It changes the route by which the seller may reach the outside buyer. The French public administration’s practical guidance describes the clause as a right of priority granted to one or more shareholders to acquire the shares that are being transferred. In its own words, “La clause de préemption (ou « clause de préférence ») accorde à un ou plusieurs associés un droit de priorité pour acquérir les actions faisant l’objet de la cession.” The same guidance states that the shares must first be offered to the beneficiary under the procedure in the articles before they can be sold to another purchaser. The source is the official Service-Public.fr page on the transfer of SAS shares.

For an international transaction, the first practical consequence is sequencing. The seller should not treat the foreign buyer’s offer as the only legally relevant offer. The offer may trigger a pre-emption procedure in favour of another shareholder. The notice generally needs to identify the proposed purchaser, give the purchaser’s address, state the number of shares and specify the offered price. Those details are not decorative. They allow the beneficiary to decide whether to match the offer and allow a court to determine whether the statutory process was actually followed.

The second consequence is that a broad commercial agreement may be insufficient. A board resolution, a shareholders’ approval, a clean corporate extract and a signed share purchase agreement do not automatically cure an omitted pre-emption notice. The French company’s articles of association are the central document. They are filed in the company’s corporate records and may be available in the due-diligence file, but the buyer should read the operative clause rather than rely on a summary in a term sheet. A translation can also conceal a material distinction between a right of approval, a right of priority and a compulsory transfer mechanism.

The SAS form gives the founders wide drafting freedom, but that freedom is exercised through the articles and within the mandatory framework of the French Commercial Code. Article L. 227-9 provides that “Les statuts déterminent les décisions qui doivent être prises collectivement par les associés dans les formes et conditions qu’ils prévoient.” In English, the articles determine which decisions must be taken collectively by the shareholders and the forms and conditions for doing so. The official text is available at Article L. 227-9 of the French Commercial Code. That drafting freedom is why the buyer must inspect the actual notice period, addressee, response method, valuation rule and consequences of silence.

Several statutory mechanisms can appear together. Article L. 227-13 allows the articles to make the shares inalienable for a period of no more than ten years: “Les statuts de la société peuvent prévoir l’inaliénabilité des actions pour une durée n’excédant pas dix ans.” This is an official Légifrance reference. Article L. 227-14 addresses prior approval: “Les statuts peuvent soumettre toute cession d’actions à l’agrément préalable de la société.” That is a separate statutory approval rule. A transaction may therefore need to pass through more than one filter: a pre-emption offer to specified shareholders, approval by the company or a corporate body, and the formalities that make the transfer effective against the company and third parties.

The legal sanction is especially important. Article L. 227-15 of the French Commercial Code states: “Toute cession effectuée en violation des clauses statutaires est nulle.” The exact provision is available on Légifrance, Article L. 227-15. Nullity is not the same as a claim for a contractual penalty. It can put the parties back into a position in which the transfer is treated as legally ineffective. The foreign buyer may then face a dispute over the purchase price, the shares, voting rights, dividends, management decisions and onward transactions completed after closing.

The word “statutory” does most of the legal work here. A pre-emption clause in the articles is not identical to a pre-emption promise in a private shareholders’ agreement. The latter can be powerful, but its remedies usually depend on the contract, the parties bound by it and the relief available under ordinary contract law. Before choosing a litigation strategy, the buyer must identify where the right is written, who signed it, whether the buyer is a party or a third party, and whether the transaction document incorporates the clause by reference.

The general contract rules provide a useful framework. Article 1103 of the Civil Code says: “Les contrats légalement formés tiennent lieu de loi à ceux qui les ont faits.” The official text appears at Article 1103 of the Civil Code. This means that a valid shareholders’ agreement binds its parties as a contract. It does not, however, transform every private promise into a statutory clause in the company’s articles. Article 1199 adds: “Le contrat ne crée d’obligations qu’entre les parties.” The full official provision is at Article 1199 of the Civil Code. A foreign purchaser that never signed the private agreement should not assume that its legal position is identical to that of a shareholder who did sign it.

That distinction affects the closing checklist. The buyer should obtain the latest certified articles, every amendment, the share transfer register, the shareholders’ register, any accession agreement and any shareholders’ agreement. The “Kbis” is the French company registration extract issued through the commercial court registry, known as the greffe; it proves registration details but normally does not reveal every private transfer restriction. The RCS, or Registre du commerce et des sociétés, is the French commercial and companies register. The INPI, the Institut national de la propriété industrielle, operates the national business formalities portal through which many company filings are submitted. Those records matter, but they do not replace the articles and the transaction file.

The buyer should also ask a narrow question: what event activates the right? Some clauses apply to any transfer of shares. Others apply only to a sale to a non-shareholder, a change of control, a transfer to a competitor, a transfer within a group or a transfer for consideration. Some include indirect transfers or transfers of the foreign parent above the French company. Others do not. The answer must be drawn from the text actually adopted by the shareholders, not from a standard model used by a foreign counsel who has not reviewed the French version.

There is a further procedural issue: how the offer is delivered. An email sent to an outdated address may be disputed. A notice addressed to the president instead of the person named in the articles may be challenged. A notice that describes a corporate buyer without identifying its ultimate acquisition vehicle may be incomplete. If the price includes earn-out, rollover equity, debt assumption or non-cash consideration, the clause may require a valuation analysis rather than a single headline number. Cross-border parties should preserve the original notice, delivery evidence, translation, attachments and time zone in which the notice was received.

B. Why the 8 July 2026 Cassation ruling removes the collusion hurdle

The central authority for the selected issue is the French Supreme Court, Commercial Chamber, decision of 8 July 2026, no. 25-11.354, ECLI:FR:CCASS:2026:CO00382. The official decision is available at courdecassation.fr, decision no. 25-11.354. The dispute involved a French SAS and cross-border entities, including a Luxembourg finance company. The Court’s reasoning is direct: “Il résulte de l’article L. 227-15 du code de commerce que l’annulation d’une cession d’actions d’une société par actions simplifiée en raison de sa contrariété à une clause statutaire n’est pas soumise à la démonstration d’une collusion frauduleuse entre le cédant et le cessionnaire.”

The English meaning is that annulment of an SAS share transfer because it conflicts with a statutory clause does not require proof of fraudulent collusion between the seller and the buyer. This is a major risk allocation rule. A foreign buyer may have acted in good faith, paid market value, commissioned due diligence and relied on a professional adviser. Those facts may be relevant to restitution, damages, costs or a separate claim, but they do not necessarily defeat the statutory nullity claim if the transfer itself violated the articles.

The Court also applied the rule to the facts. It recorded that the articles gave shareholders a pre-emption right and that another article sanctioned a transfer made in breach of that right with nullity. It then stated: “La cour d’appel ayant, en premier lieu, relevé que l’article 16 des statuts de la société Ora e-car confère aux associés un droit de préemption en cas de cession des actions de la société, et que l’article 23 des statuts sanctionne par la nullité toute cession d’action en violation du droit de préemption, en second lieu, constaté que la cession litigieuse avait été réalisée sans que les associés aient été mis en mesure d’exercer leur droit de préemption, en a exactement déduit que cette cession était nulle.” The quoted passage is from the same official 8 July 2026 Supreme Court decision.

For a foreign purchaser, the practical test is therefore not “Can the other shareholder prove that we coordinated with the seller?” The first test is “Was the transfer made in accordance with the exact statutory procedure?” The second is “Did the beneficiary have a real opportunity to exercise the right?” The third is “Does the clause itself provide for nullity, or does Article L. 227-15 apply to the relevant breach?” If the answer to the second question is no and the articles contain the relevant sanction, the absence of collusion may not save the transaction.

The decision should not be overstated. It does not mean that every private pre-emption promise automatically produces statutory nullity. It does not eliminate the need to prove the existence, scope and breach of the clause. It does not answer every question about a derivative transfer, a change of control above a foreign holding company, a transfer of economic rights without legal title or the effect of a later ratification. Those issues require the wording of the articles, the transaction steps and the governing law of each agreement.

The boundary between statutory and contractual restrictions was examined by the Commercial Chamber on 21 June 2023, nos. 21-25.952 and 22-12.045, ECLI:FR:CCASS:2023:CO00460. The official decision is at courdecassation.fr, decisions nos. 21-25.952 and 22-12.045. The Court stated: “Ce texte ne régissant pas l’exclusion d’un associé et la cession forcée de ses actions qui en résulte, la nullité qu’il prévoit vise uniquement à sanctionner la violation de toute clause statutaire ayant pour objet la cession d’actions librement consentie par leur titulaire.” In English, the statutory nullity provision targets the breach of an articles clause governing a freely agreed transfer; it does not automatically govern an exclusion mechanism and the forced transfer that follows it.

This 2023 decision is a warning against combining different mechanisms in one argument. A shareholder who wants to block a foreign buyer may invoke pre-emption, approval, exclusion, a bad-leaver clause, a forced-sale clause or a private promise. Each has a different legal source and remedy. A foreign buyer who wants to preserve the deal should ask the claimant to identify the exact clause, its legal location, the triggering event, the required notice and the sanction. A claim that uses the word “pre-emption” but relies on a private agreement may have a different outcome from a claim based on an operative clause in the articles.

Article L. 227-16 also needs to be separated from pre-emption. It provides: “Dans les conditions qu’ils déterminent, les statuts peuvent prévoir qu’un associé peut être tenu de céder ses actions. Ils peuvent également prévoir la suspension des droits non pécuniaires de cet associé tant que celui-ci n’a pas procédé à cette cession.” The official source is Article L. 227-16 of the French Commercial Code. This is a forced-transfer or exclusion-type mechanism. It does not turn a pre-emption notice into a forced sale, and it should not be used as a substitute for the notice procedure that the pre-emption clause requires.

Drafting history can matter as well. Article L. 227-19 states that clauses under Articles L. 227-13 and L. 227-17 may be adopted or amended only unanimously, while clauses under Articles L. 227-14 and L. 227-16 may be adopted or amended by a collective shareholder decision under the forms and conditions in the articles. The exact text is available at Article L. 227-19 of the French Commercial Code. If a buyer challenges a restriction as improperly adopted or amended, the corporate minutes, voting thresholds and successive versions of the articles become essential evidence.

Article 1844 of the Civil Code confirms the shareholder’s participation right: “Tout associé a le droit de participer aux décisions collectives.” The official source is Article 1844 of the Civil Code. That general rule does not erase a valid pre-emption clause, but it helps explain why a shareholder who was not informed or was not given the opportunity to vote or exercise a right may argue that the corporate process was defective. In a dispute, the company should be able to produce a coherent chain from the articles to the notice, response, corporate decision and registration of the transfer.

II. What should a foreign buyer or shareholder do when the transfer is challenged?

A. Which documents, notices and deadlines must be audited

The first response should be evidence-led and time-sensitive. A foreign buyer should create a transaction chronology on the day the challenge is received. The chronology should record the date and time of the offer, the date on which the seller notified the company, the date on which the beneficiaries received the notice, the date on which each response was sent, the signing date, the payment date, the date of delivery of the share transfer order and the date of each register entry. Use one time zone and preserve the original email headers. If documents were signed through an electronic platform, download the audit trail rather than relying on a screenshot.

The document audit should run in parallel across four layers.

• Corporate constitution. Obtain the current articles and every earlier version that could have governed the transfer. Mark the clauses on pre-emption, approval, inalienability, exclusion, forced transfer, change of control, notices and valuation. Compare the French executed version with each translation and record any difference.
• Shareholder arrangements. Obtain the shareholders’ agreement, accession deeds, side letters, call or put options and any waiver. Identify signatories, governing law, dispute forum, confidentiality restrictions and whether the foreign buyer became a party before completion. Article 1199 of the Civil Code means that a private contract generally creates obligations between its parties, so the parties must be identified precisely.
• Transaction documents. Review the offer, letter of intent, share purchase agreement, disclosure letter, conditions precedent, powers of attorney, payment instructions, completion certificate and any waiver. A “cash price” may include deferred consideration, escrow, debt assumption or a non-cash component that changes the matching analysis.
• Corporate and registry evidence. Collect shareholder notices, meeting invitations, minutes, attendance sheets, voting results, the share transfer register, the shareholders’ account and any filing or publication. A BODACC notice is a publication in the Bulletin officiel des annonces civiles et commerciales; it is not a substitute for compliance with the articles. The Kbis and the RCS record should be checked, but a clean extract does not prove that every internal restriction was respected.

Next, map the clause into a deadline table. The table should state who must notify whom, by which delivery method, with which information, during which period, and what happens if the beneficiary does nothing. Avoid translating “days” without checking whether the clause means calendar days or business days. Check whether the period starts on dispatch, receipt, acknowledged receipt or the date on which the company secretary records the notice. If the clause is silent, do not invent a safe deadline; preserve the evidence and obtain a legal position quickly.

The notice itself deserves forensic attention. The seller may have described the buyer as a foreign group without naming the exact acquisition vehicle. The buyer may have changed its registered office or legal name between the letter of intent and completion. The number of shares may omit a class of preferred shares. The price may be stated per share without explaining an earn-out. The notice may not include the draft transfer agreement even though the articles require the terms of the proposed sale. Any one of these issues can become the factual basis for an argument that the beneficiary did not receive a genuine opportunity to match the offer.

Do not assume that a beneficiary’s silence is a waiver. Silence may have legal consequences if the articles clearly provide for it, but the exact clause and proof of receipt control. Conversely, a beneficiary that responds with a conditional acceptance may not have exercised the right in the required manner. A foreign buyer should not decide that the transaction is safe simply because no shareholder objected before closing. The challenge may arise after the buyer has appointed directors, moved cash, entered leases or sold the French subsidiary to another group entity.

Check authority and representation. A foreign company may sign through a director, a local attorney or a power of attorney. The company’s constitutional documents may require two signatures or a board approval. The French SAS may have a president with authority to represent the company, but an internal approval rule can still affect the validity of a corporate decision or the liability of the person who acted. Keep the original power of attorney, apostille or legalisation, certified translation and proof of identity. If a document was signed outside France, verify the formalities required for it to be used in French proceedings.

Check the transfer formalities separately from the pre-emption procedure. A share transfer can be signed but not yet opposable to the company if the relevant notification or register entry has not occurred. The company should reconcile the transfer order, the movement of the shareholder account and the share transfer register. The tax registration of the transfer is another workstream; it does not cure a breach of the articles. The official Service-Public guidance on SAS share transfers explains the relationship between signing, registration and the company’s records at this official page.

There is also a governance question. If the shareholder claiming pre-emption is also a director, a member of a corporate body or a competitor, inspect the minutes and conflicts disclosures. Article 1844 of the Civil Code protects participation in collective decisions, but it does not create a licence to manipulate the process. The evidence should show who received the notice, who controlled the timetable, who decided not to respond and who later challenged the sale. A clear chronology can reveal whether the dispute concerns a genuine priority right or an attempt to use a procedural clause to renegotiate the price.

Finally, preserve the commercial position without making admissions. A buyer can state that it reserves all rights, requests the precise clause and asks for the claimant’s evidence while avoiding a statement that the transfer was knowingly defective. The seller should notify insurers and lenders if the transaction documents require it. The company should protect confidential information and avoid changing the share register again until the legal position is assessed. Any onward transfer can multiply the consequences and create a second innocent buyer whose rights also need to be considered.

B. How to preserve the deal, claim relief and prevent a second dispute

The correct remedy depends on whether the transfer has merely been threatened, signed, paid, registered or transferred onward. Before signing, the parties can redesign the process: deliver a compliant pre-emption notice, allow the full response period, obtain a written waiver where the articles permit it, and make closing conditional on the beneficiary’s non-exercise or valid refusal. The foreign buyer should not accept a seller’s promise to “deal with the shareholders later” if the statutory clause has already been triggered.

After signing but before completion, the buyer should seek a standstill or an agreed sequencing protocol. The protocol can identify the documents to be sent, the person responsible for delivery, the response deadline, the treatment of a matching offer, the handling of escrow and the consequences of a dispute. It should not attempt to override the articles by private wording. Article 1103 of the Civil Code supports the binding force of a valid contract between its parties, but the contract cannot silently amend the company’s articles or remove a right held by a non-signatory shareholder.

After completion, the buyer should consider urgent relief. The appropriate French court procedure may depend on the claim, the arbitration clause, the company’s registered office and the parties’ contractual forum. The buyer may need to seek an interim order preserving access to corporate records, preventing a further transfer, protecting voting rights or preventing disposal of the purchase price. The court will look at the documents and the urgency; a late request made after the buyer has reorganised the business may be more difficult to manage.

The substantive remedies must be separated. If the statutory transfer is annulled, the parties may face restitution of the shares and the price, subject to the court’s reasoning and the transaction’s subsequent history. If the seller breached a warranty or an indemnity, the buyer may have a contractual claim against the seller. If a private shareholders’ agreement was breached, Article 1217 of the Civil Code lists possible sanctions: “La partie envers laquelle l’engagement n’a pas été exécuté, ou l’a été imparfaitement, peut : – refuser d’exécuter ou suspendre l’exécution de sa propre obligation ; – poursuivre l’exécution forcée en nature de l’obligation ; – obtenir une réduction du prix ; – provoquer la résolution du contrat ; – demander réparation des conséquences de l’inexécution.” The official source is Article 1217 of the Civil Code.

Those contractual remedies should not be confused with the statutory nullity rule. A damages claim against a seller who misrepresented the articles may coexist with a challenge to the transfer, but it may not restore the buyer’s corporate position. The buyer should model several outcomes: the pre-empting shareholder acquires the shares, the transaction is renegotiated, the transfer remains effective, the price is returned, or a court orders a new procedure. Each outcome affects tax, financing, management control and the foreign group’s reporting.

Can a pre-emption beneficiary simply take the buyer’s place at the same price? Often the answer depends on the exact clause and whether the beneficiary made a timely and unconditional exercise. The price-matching analysis can be difficult where the foreign buyer offered a package: cash plus a loan, a non-compete, a rollover, assumption of liabilities or a strategic supply agreement. The company should not rewrite the economic terms after the fact. Preserve the full offer and obtain a valuation record that explains which terms are monetary and which are personal to the buyer.

Can a foreign buyer argue that it was a good-faith third party? Good faith may matter to other claims, but the 8 July 2026 decision makes it dangerous to treat good faith as an automatic defence to a breach of a statutory pre-emption clause. The safer analysis is procedural: did the buyer receive and review the articles, was the clause triggered, was the notice complete, did the beneficiary receive a real opportunity, and was the transfer completed only after the statutory route had ended? If the answer is uncertain, the buyer should not rely solely on the absence of evidence of collusion.

For founders, prevention is cheaper than post-closing litigation. The articles should identify the triggering event, the beneficiaries, the notice content, the delivery method, the exercise period, the matching mechanics, the valuation process, the consequences of partial exercise and the effect of a buyer substitution. The shareholders’ agreement can deal with commercial arrangements that should remain confidential, but the founders should decide which restrictions need the corporate effect of the articles. Every amendment should be approved using the required threshold and reflected consistently in the next executed version.

For a foreign parent, the due-diligence request list should include a specific “transfer restrictions” section. Ask for all versions of the articles, all shareholder side agreements, all waivers, every transfer since incorporation, the share register, the shareholder account and all notices delivered under a restriction. Ask the seller to identify any threatened claim, unexercised option or dispute over the validity of a previous transfer. An English-language summary is useful, but it should be a map to the French documents, not a substitute for them.

For a shareholder who wants to block a transaction, the disciplined route is equally important. Identify the exact statutory clause, send a notice that preserves the right, state the matching terms clearly and keep proof of timely delivery. Do not rely on a general objection to a foreign buyer. Nationality, residence or the use of a foreign holding company does not by itself establish a breach. The legal argument should connect the proposed transfer to the triggering language and show that the beneficiary was ready and able to exercise the right under the articles.

For the company, the governance file should show neutrality. The company should not give one bidder privileged access to information that changes the economic terms without considering the effect on the pre-emption beneficiary. It should keep a controlled version of the articles, record the person responsible for each notice and require a closing checklist signed by the president and counsel. If the company has employees or an operating business, business continuity should be planned separately so that a share-transfer dispute does not interrupt payroll, banking or customer contracts.

The French company’s purpose also matters. Article 1832 of the Civil Code begins: “La société est instituée par deux ou plusieurs personnes qui conviennent par un contrat d’affecter à une entreprise commune des biens ou leur industrie…” The official text is at Article 1832 of the Civil Code. The quote reflects the contractual foundation of the company, but the modern SAS combines that foundation with a detailed statutory and corporate framework. A cross-border buyer should therefore analyse three relationships at once: the company and its shareholders, the seller and buyer under the acquisition agreement, and the shareholders among themselves under any private agreement.

A final prevention measure is to prepare an English closing memorandum that reproduces the operative French clause, identifies the exact source and records the date on which each condition is satisfied. The memorandum should state whether the clause is statutory or contractual, whether it has a nullity sanction, whether an approval is also required and which documents must be filed or entered in the company records. This is not bureaucratic excess. It gives the foreign board, finance team and advisers one controlled explanation of why the transaction can close and what evidence proves it.

For future readers who are assessing the wider acquisition process, the company-level share transfer steps should be read together with this site’s foreign-buyer share-transfer approval, tax and closing checklist. The current article addresses the narrower pre-emption risk. It should also be connected to the firm’s French company formation and corporate-law hub, where a founder can place the restriction analysis in the wider structure of a French business.

Conclusion

A French SAS can block a foreign buyer through a statutory pre-emption clause even when the buyer acted honestly and there is no evidence of collusion. The 8 July 2026 Commercial Chamber decision, no. 25-11.354, makes the central point clear: where the transfer conflicts with the articles, Article L. 227-15 does not require proof of fraudulent coordination between seller and buyer. The decisive work is therefore documentary and procedural. Read the French articles, distinguish them from the shareholders’ agreement, identify the trigger, deliver a complete notice, respect the response period and preserve evidence of every step.

For a foreign founder or investor, the safest time to address the risk is before the offer becomes irrevocable. For a shareholder seeking to exercise the right, the strongest position comes from a precise, timely and fully documented exercise rather than a general objection to foreign ownership. In either case, the transaction should be reviewed as a chain: statutory restriction, corporate approval, contract, payment, register entry and onward ownership. A short pre-emption clause can control the validity of an otherwise sophisticated international acquisition.
