A foreign founder can have signed articles, paid the share capital and submitted a complete filing to the French one-stop shop, yet still be unable to answer a bank or investor’s first question: what document proves that the French company legally exists, who may bind it, and whether the information is current? The answer is not a single universal certificate. A Kbis, an RNE registration certificate, a SIREN number, a SIRET number and a filing receipt prove different stages and different facts.

This distinction matters when a foreign bank opens a corporate account, when an investor releases funds, when a group signs an intercompany agreement, or when a regulated supplier asks for evidence before onboarding the new French entity. The French terms also create avoidable confusion: INPI is the National Institute of Industrial Property, RCS is the Trade and Companies Register, RNE is the National Register of Enterprises, greffe means the court registry, and Kbis is the official company extract issued by the competent registry.

This article sets out a document strategy for a foreign-owned Société par Actions Simplifiée (SAS, simplified joint-stock company), Société par Actions Simplifiée Unipersonnelle (SASU, one-person SAS), Société à Responsabilité Limitée (SARL, private limited company), or another French company. It explains what each document proves, how the company’s authority and beneficial-owner chain must be added, how foreign documents should be prepared, and what to do when a bank, investor or registry rejects an otherwise genuine file.

I. What proves that a French company legally exists after the INPI filing?

A. Which document should a foreign bank or investor request: Kbis, RNE extract, or filing receipt?

The legal starting point is registration, not the signature of the articles. Article 1842 of the French Civil Code states that companies other than the specified exceptions “jouissent de la personnalité morale à compter de leur immatriculation”. For a commercial company, Article L. 210-6 of the Code de commerce uses the same practical rule: “Les sociétés commerciales jouissent de la personnalité morale à dater de leur immatriculation au registre du commerce et des sociétés.” A signed constitution file therefore shows an intended company; registration shows the company as a legal person.

That distinction should govern the document sent to a foreign bank or investor. A receipt issued while the filing is being processed can explain that an application exists. It does not necessarily prove that the company can hold assets, enter into contracts in its own name or receive an investment as an existing legal person. The Court of Cassation made that point in Commercial Chamber, 29 November 2023, no. 22-21.623: the company acquires legal personality at RCS registration, and people acting for a company in formation remain exposed unless the registered company later takes over the commitments. A foreign investor should not treat “company in formation” as interchangeable with “registered French subsidiary”.

Four documents are often confused:

• The RDDCE. The récépissé de dépôt de dossier de création d’entreprise is the receipt for the filing of the creation dossier. It is useful when a company needs to show that its application is pending, but it is a transitional document. It normally contains an “awaiting registration” status and should not be presented as a final Kbis.
• The SIREN number. The nine-digit Système national d’identification et du répertoire des entreprises et de leurs établissements number identifies the legal unit. It is not itself a full extract and it does not, by itself, prove who has signing authority or whether the latest articles were filed.
• The SIRET number. The fourteen-digit Système d’identification du répertoire des établissements number identifies an establishment by combining the SIREN with a five-digit establishment number. A company may have several SIRET numbers, while the legal entity has one SIREN.
• The Kbis or RNE certificate. The Kbis is the company extract issued by the greffe for a legal person registered in the RCS. The RNE certificate is the free registration document available through the INPI and DATA INPI services. Each should be downloaded from its official source and checked against the other information in the file.

The INPI’s official explanation of documents proving an enterprise’s existence describes the RNE certificate as a document that proves legal existence and confirms the information entered in the RNE. It explains that the certificate can be obtained through DATA INPI and that it includes the SIRET, registration date, APE code, main activities and, where applicable, share capital. The same page explains that the Kbis is an official document issued by the commercial court registries and that the greffe provides it after the formality has been validated. The INPI Guichet unique transmits the filing; it is not the issuer of the Kbis.

A bank or investor asking for “a Kbis” may therefore be asking for a recent RCS extract because it wants the registered company’s legal identity, form, registered office, directors and registry status. If it accepts an RNE certificate, that document may be sufficient to establish the registration facts, but the counterparty may still ask for articles, a director resolution and beneficial-owner evidence. Acceptance policies are not identical. A company should ask the recipient whether it requires an RCS Kbis, an RNE certificate, or both, rather than arguing after submitting the wrong document.

The statutory framework supports this layered approach. Article L. 123-1 of the Code de commerce identifies companies and certain other entities that are registered in the RCS. Its wording begins: “Il est tenu un registre du commerce et des sociétés auquel sont immatriculés, sur leur déclaration”. The RCS is therefore a public legal registry, not merely a private directory. The RNE is the wider national register that centralises enterprise information. The two systems interact, but a document from one registry should not be described as if it were issued by the other.

A useful first-stage pack for a foreign bank or investor is the following:

Stage	Primary proof	What it proves	What it does not prove alone
Filing pending	RDDCE and filing summary	A creation application was submitted	Final legal personality or final signing authority
Registration completed	Kbis and RNE certificate	Registration, identity and public registry data	That the foreign signatory has authority to use the account
Operational onboarding	Current Kbis or RNE certificate plus articles	Company identity, legal form, objects, capital and governance framework	Source of funds or ultimate beneficial ownership by itself
Investment closing	Corporate approvals, ownership chart and beneficial-owner file	Authority, ownership, control and transaction approval	That every commercial risk has been verified

A date is important. Many banks request a Kbis issued within three months, although that age limit is generally an internal onboarding rule rather than a universal validity period for every legal use. An investor may require an even fresher extract at signing and at closing. The company should download a new document immediately before the relevant submission, record the retrieval date, and preserve the electronic PDF with its verification features. A screenshot of an old search result is weak evidence where the director, registered office or beneficial-owner chain has changed.

The official Service-Public page on obtaining a K or Kbis extract confirms that the Kbis proves the legal existence of a commercial enterprise and is commonly requested to open a professional bank account or buy equipment from a supplier. The same page explains that the free RNE registration certificate can serve as an equivalent registration document for many procedures. A foreign founder should use this official distinction in correspondence with a counterparty that requests a Kbis without explaining whether an RNE document would satisfy its compliance policy.

There is also a practical difference between a company that is registered and a company whose latest changes have been recorded. A Kbis may show a new registered office or director after the change has been filed, while the articles, shareholder register or foreign parent resolution may still show the old position. The proof pack must be internally consistent. A foreign bank is entitled to ask why the Kbis says one person is president while the corporate resolution names another. An investor may require an officer certificate or a management representation confirming that no unfiled change affects the transaction.

B. How do the articles, capital, director and beneficial-owner records complete the proof?

Registration proves the company’s existence, but a bank or investor also needs to know what the company is authorised to do and who may act for it. The articles of association show the legal form, registered office, share capital, corporate purpose, duration, decision-making rules and limits on authority. They should be supplied in the version filed at incorporation, together with any later amendment relevant to the transaction. If the articles are long, prepare a short English index, but do not replace the certified or signed French version with an informal translation.

Article R. 123-53 of the Code de commerce specifies the data declared by a company in its registration application: its name, legal form, capital, registered office, principal activities, duration and, where relevant, financial year-end and establishments. The article begins, “Dans sa demande d’immatriculation, la société déclare, en ce qui concerne la personne morale”. These fields explain why a counterparty compares the articles with the Kbis and the registration form. If the business description in a pitch deck differs materially from the registered object or principal activity, the inconsistency may lead to a compliance question.

The capital evidence has two functions. The certificate of deposit of funds helped the company complete its incorporation file; the Kbis shows the registered capital after incorporation. The bank or investor may still ask for the subscription list, the deposit certificate, evidence of a capital increase, or a shareholder resolution approving new securities. The capital amount is not a guarantee that the money remains in the company. It is a registered corporate fact, and the financial institution may separately ask for source-of-funds evidence under its anti-money-laundering obligations.

The director’s authority should be documented separately from the company’s existence. For an SAS, the president is the legal representative, but the articles can create other bodies or contractual delegations. For a SARL, the gérant is the manager and the legal representative. If a foreign parent is a shareholder or corporate president, the file must identify the natural person who acts as its permanent representative or authorised signatory. A passport copy does not establish authority on its own. The company should add the appointment decision, the parent’s board or shareholder resolution, the power of attorney and the signatory’s specimen signature where the counterparty requires it.

The Service-Public guide to registering a company lists the articles, appointment act, registered-office evidence, legal-announcement certificate and capital-deposit certificate among the documents required for a French SAS or SARL. For a legal-person director, it also refers to the foreign entity’s Kbis or equivalent existence document, its translated statutes when it is outside the European Union, and the identity and declaration of the permanent representative. Those requirements are useful benchmarks for an investor’s due-diligence pack, even though a private bank may ask for additional information.

The beneficial-owner file is a separate layer. Bénéficiaire effectif means the natural person who ultimately owns or controls the company. A foreign parent’s corporate registration document may show that it owns the French subsidiary, but it does not identify the natural person at the end of a multi-level ownership chain. The company should prepare a dated ownership chart showing every intermediate entity, percentage of capital, voting rights, special rights and control agreement. It should identify the ultimate natural person or explain the statutory fallback where no individual meets the ownership threshold.

Article L. 561-5 of the Code monétaire et financier requires the relevant professionals, before entering a business relationship, to identify the client and, where applicable, the beneficial owner, and to verify the information using reliable written evidence. The text states: “Identifient leur client et, le cas échéant, le bénéficiaire effectif” and “Vérifient ces éléments d’identification sur présentation de tout document écrit à caractère probant.” A bank’s request for the ownership chain is therefore not proof that the French company is defective; it is part of the bank’s customer-identification duty.

Article L. 561-2-2 defines the beneficial owner by reference to the natural person or persons who ultimately own or control the customer or for whom a transaction is carried out. Article R. 561-1 supplies the ownership and control indicators, including the holding of more than 25 percent of capital or voting rights and the possibility of identifying a person who exercises control by other means. Where the chain ends in a widely held listed company, a bank may still require evidence explaining why no individual owner is identified and who exercises senior management control.

The company should also check whether the beneficial-owner declaration filed with the RCS and INPI is current. Article L. 561-46 of the Code monétaire et financier requires companies within its scope to declare beneficial-owner information for the register. The declaration is not a substitute for the Kbis, and it is not a public list of every shareholder. It is a compliance record that may be accessed in the statutory conditions. A mismatch between the filed declaration, the shareholder register and the foreign parent’s chart can delay an account or investment.

Keep the following documents in the beneficial-owner folder:

1. the French company’s current Kbis or RNE certificate;
2. the French company’s filed articles and any relevant amendment;
3. the foreign parent’s official registration extract or equivalent, with the issue date;
4. constitutional documents for each intermediate holding company;
5. the ownership and voting chart, showing percentages and control rights;
6. passport or identity evidence for each ultimate natural person identified;
7. the French beneficial-owner declaration receipt or filing evidence;
8. the appointment and authority documents for the person who will sign for the French company; and
9. a short English explanation of any nominee, trust, foundation, listed-company or dispersed-ownership issue.

Do not send a private shareholder register to every recipient without considering confidentiality. A bank conducting regulatory checks may have a legal basis to request it. A potential commercial investor may need only the ownership information relevant to its investment and anti-money-laundering review. The company can ask the recipient to identify the legal or contractual reason for each additional document, provide a secure data room and watermark sensitive copies. This keeps the file useful without treating every confidential document as a public registry extract.

For a foreign founder, the strongest proof pack is therefore not “one Kbis”. It is a coherent chain: public registration, filed constitutional documents, authority evidence, capital evidence, ownership evidence and a clear explanation of what is still pending. Each item answers a different risk. The counterparty can verify the company’s identity, the signatory’s authority, the ownership chain and the transaction without guessing from an incomplete PDF.

II. How should a foreign founder assemble and defend the cross-border document pack?

A. Which translations, certifications and updates prevent rejection?

French registration documents are often issued in French, while the bank, fund or parent group operates in English. Translation strategy should be decided before the request is sent. A plain English translation can explain a French Kbis to a relationship manager. A certified translation may be required by an investor’s counsel, a foreign notary, an apostille authority or a regulated bank. The requirement depends on the recipient and the country where the document will be used. French law does not turn every French company document into a document requiring an apostille; the company must ask the destination party what form it accepts.

The same distinction applies to documents issued by the foreign parent. An overseas certificate of incorporation, certificate of incumbency, board resolution, articles, register of directors or good-standing certificate may need a recent issue date, an apostille or legalisation, and a French translation for an INPI or registry filing. A foreign bank may instead accept the original electronic extract and an English translation. The file should state which version is authoritative, who translated it, and whether the translation is certified. Mixing an unofficial translation with a certified French filing can create a question about whether the two texts match.

A practical pack can be divided into four folders:

• Identity folder: current Kbis, RNE certificate, SIREN and SIRET details, registered-office evidence, company contact details and a timeline showing the registration date.
• Constitution folder: signed articles, appointment acts, legal-announcement certificate, capital-deposit certificate, subscription list, beneficial-owner filing and any shareholder agreement relevant to control.
• Authority folder: president or gérant appointment, foreign parent resolution, permanent-representative evidence, delegation or power of attorney, identity documents and signing policy.
• Transaction folder: investment resolution, bank mandate, source-of-funds explanation, investor term sheet, intercompany agreement, tax residence information and any regulated-activity authorisation.

Name files so that a foreign reviewer can understand them without opening ten documents. A good convention is “01_French_Kbis_2026-08-24.pdf”, “02_INPI_RNE_certificate_2026-08-24.pdf”, “03_Articles_filed_version.pdf”, and “04_Foreign_parent_authority_resolution.pdf”. Preserve the original downloaded file and the translated or certified copy separately. Do not edit a registry PDF to add an English label. Add a cover sheet or a translation instead.

Cross-check five fields in every document: legal name, SIREN, registered office, legal representative and capital. Then cross-check the ownership chain and date. A common problem is a transliteration difference in the foreign parent’s name, an old registered office in the bank form, or a director whose appointment has been signed but not yet registered. Explain a genuine timing gap in a dated memorandum. Never conceal it by sending an older Kbis that shows a person who no longer acts.

The French filing process has its own response calendar. Article R. 123-97 of the Code de commerce states that the greffier registers the company within one clear working day after receiving the application, and that missing information or documents must be supplied within fifteen days after the request. It also provides for a reasoned refusal if the application is not regularised or does not comply with the applicable rules. A founder who receives a request from the Guichet unique should upload a complete response within the deadline and retain proof of submission.

The same provision provides that, where a file requires particular examination, the greffier may give a reasoned notice and extend the decision period to five clear working days. The notice should be read carefully: it is not the same as a final refusal. If the registry refuses the registration, the decision must identify the available remedies. The company should record the date of notification, the reasons given, the document that cures each reason and the person responsible for the reply.

Article 1842 of the Civil Code, Article L. 210-6 and the registration extract should be used consistently in an investment agreement. If the agreement is signed before registration, it should identify the company as “société en formation”, define who acts for it and include the mechanism for taking over the commitment after registration. The Commercial Chamber, 10 February 2021, no. 19-10.006, considered the effect of contracts entered into during formation and stressed that the document’s wording and the identity of the contracting party matter. A foreign group should not backdate the company’s legal existence to the date on which the articles were signed.

The Court had already explained in Civil Chamber 3, 5 October 2011, no. 10-14.485, that submitting an application to a former business-formality centre did not give the company legal personality before its registration. The current Guichet unique changes the filing channel, not the legal principle. An INPI filing receipt, SIREN allocation or preliminary business identifier should not be represented as a final Kbis when the registry has not yet registered the company.

Foreign parent documents require a separate authority check. Ask the parent to provide its current official extract, its constitutional rules on board or shareholder approval, and a resolution that identifies the French company, the transaction and the signatory. If the resolution is signed by a director under a delegation, include that delegation. If a local representative signs the French bank mandate, the power of attorney should state whether it covers account opening, payment instructions, borrowing, security, investment subscription or only document delivery. A generic sentence allowing “all business matters” may be rejected by a bank’s control team.

Finally, refresh the pack after each trigger: new director, registered-office change, capital increase, transfer of shares, change in beneficial owner, change in foreign parent, new establishment, change of principal activity or material change to the investment. The RNE and Kbis are snapshots. A document that was accurate at incorporation may not prove authority at closing six months later. A compliance calendar should assign an owner to the next refresh and keep an archive of the previous extract so that the history remains understandable.

B. What should the company do when the bank or investor refuses the documents?

A refusal should be classified before it is challenged. There are at least four different situations: the company is not yet registered; the registry has issued a reasoned refusal; the bank cannot complete customer identification; or the investor is applying a contractual due-diligence standard that is stricter than the legal minimum. Each situation needs a different response. A founder who simply sends the same Kbis again may lose time and create the impression that the company does not understand the request.

For a registry issue, obtain the written reason and map it to a document. If the issue concerns the registered office, supply a lease, domiciliation agreement, title or other document showing the company’s right to use the premises. Article L. 123-6 and the related RCS provisions place registry matters under the greffier’s supervision, while Article L. 123-11 requires a legal person requesting registration to justify its enjoyment of the premises used for its registered office. The evidence must identify the address and the contracting or owning party; a vague letter from a foreign parent may not do so.

If the issue concerns a foreign identity document, Article L. 123-2 of the Code de commerce expressly says that “Le greffier peut vérifier par tout moyen la cohérence et la validité des pièces d’identité étrangères fournies.” The company should therefore provide a clear passport copy, a matching spelling, the required certification, a translation when requested and an explanation of any middle name or transliteration. It should not respond by submitting a different spelling merely to avoid a mismatch.

If the bank refuses because it cannot complete its anti-money-laundering and counter-terrorist-financing review, the bank may be acting under a legal constraint rather than making a decision about the company’s validity. Article L. 561-8 of the Code monétaire et financier provides that, when the required identification cannot be completed, the professional “n’établit ni ne poursuit aucune relation d’affaires”. That rule explains why a bank can pause or decline onboarding when it cannot identify the natural persons behind a foreign ownership chain. It does not mean that the bank must disclose whether a suspicious-transaction report was made.

Respond to an AML request with a structured ownership and source-of-funds pack. Include the bank’s requested corporate documents, a diagram with percentages and control rights, identity evidence, the purpose of the account or investment, expected flows, countries involved, counterparties, funding agreements and proof of the initial capital transfer. Article L. 561-10-2 requires enhanced examination in situations involving complex or unusually large operations or operations without an apparent economic justification; the examination can concern the origin and destination of funds and the purpose of the transaction. A concise explanation connected to the company’s actual business is more persuasive than a large unindexed upload.

Do not ask the bank to confirm whether it filed a report with TRACFIN, the French financial intelligence unit. Article L. 561-15 requires suspicious-transaction reporting in the situations described by the statute, including attempted transactions, but the reporting process is confidential. The company can ask which non-confidential document or factual inconsistency prevents onboarding. It can correct a beneficial-owner filing, explain a transaction, or provide a new bank relationship, but it should not demand information that the bank is legally unable to disclose.

The bank’s refusal should also be distinguished from a refusal to provide the statutory right to an account. Article L. 312-1 of the Code monétaire et financier provides a right-to-account mechanism for a person domiciled in France under its conditions, with the Banque de France designating a credit institution after a refusal. The procedure has its own eligibility and document requirements. It does not compel a bank to ignore customer-identification rules, and it does not convert a pending company-formation receipt into a final registration extract. A company should evaluate eligibility and prepare the Banque de France file separately.

If an investor rejects the pack, ask whether the concern is legal existence, authority, ownership, sanctions, tax residence, source of funds or commercial risk. The response may be an officer certificate, a legal opinion, an updated Kbis, an English translation, a parent resolution, a beneficial-owner filing or a contractual representation and warranty. An investor’s private due-diligence request is not automatically an accusation. At the same time, a company should not give an absolute representation that all documents are current if a director change or beneficial-owner update is still pending.

The remedy for an uncompleted or incorrect filing is usually regularisation, not a new company. Article L. 123-5-1 allows an interested person or the public prosecutor to ask the president of the court, sitting in urgent proceedings, to order the manager to deposit the required documents or acts in the RCS, potentially under a penalty payment, and allows the court to appoint a representative to complete the formality. The wording refers to a person who “peut enjoindre sous astreinte” the filing. A founder should preserve this route for a real registry failure and obtain legal advice before issuing a formal application.

There are consequences for false or incomplete information. Article L. 123-38 punishes, when done in bad faith, inaccurate or incomplete information supplied for registration, modification or radiation with a fine and imprisonment. Article L. 123-38-1 provides an administrative fine of €7,500 for failure to be registered in the RNE in the situations covered by the article. The solution to a rejected document is a truthful correction with a traceable explanation, not an altered PDF or an invented address.

The case law reinforces the need to keep the pre-registration period separate from the registered company. In Commercial Chamber, 11 December 1984, no. 83-15.526, the Court held that a commercial company not registered in the RCS had not acquired legal personality and could not be placed in the relevant insolvency procedure. In Commercial Chamber, 10 February 2021, no. 19-10.006, the Court analysed who was bound by contracts made during formation by looking at the wording and the identity of the contracting party. In Civil Chamber 3, 5 October 2011, no. 10-14.485, a filing step before registration did not give the entity legal personality. These decisions are old or fact-specific in part, but the principle remains essential for a foreign founder seeking bank or investment funds.

Use the following response sequence when the document pack is refused:

1. request the refusal or deficiency in writing and identify the recipient’s exact document requirement;
2. separate pending registration, registry refusal, bank compliance refusal and investor diligence;
3. check every legal name, number, address, director, capital figure and date across the file;
4. download a current Kbis and RNE certificate from the appropriate official source;
5. obtain the filed articles, appointment act and corporate authority resolution;
6. rebuild the foreign parent and beneficial-owner chain with reliable registration documents;
7. provide a certified or clearly identified translation and the required legalisation or apostille only where the recipient requires it;
8. answer an INPI or greffe request within the stated period and preserve the submission receipt;
9. answer a bank’s factual compliance questions without asking it to reveal confidential reporting information; and
10. escalate a reasoned registry refusal, court application or contractual dispute with the complete evidence bundle.

A foreign-owned French company should also keep a one-page “status certificate” in English. It can state the company’s legal name, SIREN, SIRET, RCS and registered office; registration date; legal form; capital; current president or gérant; beneficial-owner filing date; main activity; and the documents attached. The certificate should be signed by the legal representative and expressly say whether any change is pending registration. It is an explanatory cover document, not a replacement for the Kbis. Used correctly, it allows a foreign reviewer to understand the official documents without asking the founder to improvise explanations in a second language.

The company should link this procedure to its wider French company formation and corporate structuring practice, its broader English guide to setting up a business in France, and its guide to opening a French business bank account as a foreign company. Those pages cover the wider choices. The present document pack is the narrower post-registration proof needed when a particular bank, investor or registry asks: “show us exactly what exists, who controls it and who can sign.”

Conclusion

A foreign bank or investor should not receive a single unexplained PDF and be expected to infer the status of a French company. The RDDCE proves that a filing is pending; the SIREN identifies the legal unit; the SIRET identifies an establishment; the RNE certificate confirms current national-register data; and the Kbis is the official RCS extract for a registered commercial company. The articles, capital records, director appointment, authority resolution and beneficial-owner chain answer the next questions: what is the company allowed to do, who may bind it and who ultimately controls it?

The most reliable process is to build the pack in layers, download current official records, explain any timing gap, translate foreign documents carefully, and refresh the file after every governance or ownership change. If the registry or bank refuses the file, identify the precise reason, correct it truthfully and preserve the procedural record. Registration is a legal event, not a branding exercise, and a foreign-owned company gains credibility when its public records, corporate documents and transaction evidence all tell the same story.
