A foreign founder may negotiate in English, manage a French team in English, and receive a draft prepared by a group headquarters abroad. That commercial reality does not remove the French language rules that apply to an employment relationship performed in France. The decisive question is not whether the employee speaks English. It is whether the document is the employment contract, whether it imposes obligations or determines rights, and whether the employer can prove where the document came from and whom it was intended for.

The short answer is therefore qualified. An English text can be used as a translation or working version, but a written French employment contract should be the contractual foundation. For a foreign employee, the employee may request a translation in their own language, and the statutory rule can make that version particularly important in litigation. An English-only contract also creates separate risks for a fixed-term contract, variable compensation, working-time documents, policies, and the choice of forum.

This article addresses the foreign founder or foreign company hiring someone to work in France. It does not address the immigration status of an individual moving to France. It explains the main French acronyms used in the process: a CDI is a contrat à durée indéterminée, or open-ended employment contract; a CDD is a contrat à durée déterminée, or fixed-term contract; a DPAE is the prior declaration of hiring; and URSSAF is the body that collects French social-security contributions and family-allowance contributions.

The contract should be reviewed alongside the company’s French company formation and corporate-structuring framework, because the identity and authority of the employing entity must be correct before language questions can be resolved.

I. Can a French employee sign an English employment contract?

A. Why the French version is the legal starting point

The starting point is Article L. 1221-3 of the French Labour Code. Its first sentence states, in the exact wording of the official text, Le contrat de travail établi par écrit est rédigé en français. The rule is reproduced in the current version of the article on Légifrance. In English, the practical meaning is that an employer hiring for work in France should not treat an English draft as the only operative contract merely because the company group uses English internally.

The same article deals expressly with the foreign employee. When a foreign employee has a written contract, a translation must be prepared in that employee’s language if the employee requests it. The statute also says Les deux textes font également foi en justice. If the two texts conflict, the text written in the foreign employee’s language may be invoked against that employee. This is not a general permission to choose English as the controlling language. It is a protection for the employee who asks for a translation in the language the employee uses.

The employee’s fluency in English does not by itself answer the question. The legal test concerns the nature of the document and the statutory language requirement. A founder should therefore avoid a clause stating that the English version alone is authoritative when the contract is being performed in France. A safer architecture is a French contractual version, accompanied by a carefully checked English translation for negotiation and day-to-day management.

Article L. 1221-1 confirms that the employment contract is subject to ordinary contract-law rules and may be established in the form chosen by the parties. That freedom of form does not override the language rule. The official text is available in the Légifrance section on the formation of the employment contract. The correct reading is: the parties have flexibility in drafting, but not a licence to remove mandatory protections through an English-only document.

The distinction between a CDI and a CDD also matters. A CDI is normally the general form of employment. A CDD, by contrast, must be in writing, state its precise reason, and contain the statutory information required by Article L. 1242-12 of the Labour Code. The current text on Légifrance states that the fixed-term contract is written and includes, among other matters, the reason, term, position, applicable collective agreement, trial period, remuneration, and supplementary-pension information. A foreign company that signs an English-only CDD creates an avoidable argument that the mandatory written form was not properly satisfied and that the relationship should be treated as an open-ended contract.

French case law shows why the risk is practical rather than theoretical. In Cass. soc., 29 June 2011, no. 09-67.492, the Court of Cassation stated that an employee could rely on the lack of French for documents fixing the objectives used to calculate variable pay. The decision records the rule that tout document comportant des obligations pour le salarié ou des dispositions dont la connaissance est nécessaire pour l’exécution de son travail doit être rédigé en français. The immediate dispute concerned bonus documents, not the whole employment contract, but it illustrates the wider consequence: English wording can become unusable against the employee when it is used to impose or calculate a contractual obligation.

The same logic applies to an English offer letter that contains the salary, trial period, notice rules, non-compete restrictions, intellectual-property assignment, or bonus formula, followed later by a French document that is shorter or inconsistent. A court may have to determine which document formed the agreement, whether the employee understood the relevant terms, and whether the employer can rely on the English wording. The founder’s objective should be to eliminate that evidential dispute before the employee starts work.

A French employee may sign an English translation for convenience, but the signature does not cure an absence of the French contractual text. The signature proves assent to a document; it does not automatically validate every clause that French law requires to be communicated in French. For that reason, the signing package should show the French version, the English translation, the date of both documents, and the relationship between them.

B. How to build a bilingual contract that survives a dispute

The best drafting method is not to translate an English contract at the end of the process. It is to create a French legal version and an English explanatory version in parallel. The French version should identify the legal employer, the registered address, the employee’s role, the place of work, the start date, the remuneration, the applicable collective agreement, the working-time arrangement, the trial period, paid leave, benefits, confidentiality, intellectual property, termination procedure, and any valid post-termination restriction. The English version should reproduce the same numbering, defined terms, dates, amounts, and attachments.

The document should state that the French version is the contractual reference for a French employment relationship, while the English version is supplied to facilitate understanding. That wording must be adapted when Article L. 1221-3 gives a foreign employee the right to request a translation in the employee’s own language. If the employee asks for that translation, the employer should not answer with an informal summary. It should provide a complete translation, keep evidence of the request and delivery, and record which documents were supplied.

Use the same version-control discipline as a regulated company would use for a financing document. Each version should carry a date, a document name, and an indication of whether it is the initial contract, an amendment, a schedule, or a translation. Attachments such as a commission plan, remote-working policy, confidentiality schedule, or equity plan should be listed in the French contract. If an attachment changes remuneration or imposes a continuing obligation, it should be translated and signed at the same time.

Do not rely on a short disclaimer saying that the employee has “full professional English”. That fact can help prove understanding, but it does not replace the statutory language framework. In Cass. soc., 11 October 2023, no. 22-13.770, the Court of Cassation held that the fact that English was used in the company did not by itself make English performance documents enforceable. The Court stated that the language exception was not applicable to documents received from abroad unless that foreign origin had actually been established. Its concise formulation was cette règle n’est pas applicable aux documents reçus de l’étranger ou destinés à des étrangers, followed by a factual check of the condition.

The decision is particularly relevant to a foreign founder because it prevents a common shortcut. A group may use a common English template, but a French subsidiary that distributes the template to a French employee cannot automatically say that every English document is a foreign document. The employer should preserve the email, portal record, or group instruction showing who issued the document, from which entity it was received, and whether it was meant for an employee abroad or for the French workforce.

Electronic signing is possible if the technical process identifies the signatories, preserves the signed document, and makes later alteration detectable. The electronic-signature package should nevertheless contain the French contract and the translation as separate, identifiable files. A platform certificate cannot resolve a contradictory bilingual draft. The evidence must show what the employee actually saw before signing and which attachments were included.

Foreign terms may still appear in a French contract. Article L. 1221-3 requires an explanation in French where the job cannot be described by a French term with the same meaning. A job title such as “Chief Revenue Officer” may therefore be accompanied by a French description of the responsibilities, authority, reporting line, and classification. The title should not be used to obscure the actual role, especially where the role affects overtime, managerial status, or the applicable collective agreement.

The bilingual structure should also cover the collective agreement. The collective agreement is not simply a commercial preference. It can determine the classification, minimum salary, trial period, notice period, working time, paid leave, and post-termination rules. The employer should identify the applicable IDCC, meaning the French identification number of the collective agreement, and give the employee the relevant information in the required form. A foreign group policy should not silently replace a mandatory French collective-agreement rule.

A useful contract schedule can make the process transparent:

Document	Safe drafting approach	Foreign-founder evidence
French employment contract	French legal version, signed and dated	Identity of the French or foreign employing entity and its address
English translation	Complete translation with matching clause numbers	Delivery record and acknowledgment that it is a translation
Bonus or commission plan	French version before the performance period begins	Source, date, objectives, calculation method, and proof of delivery
Group policy	French version where it imposes obligations or is needed for the job	Proof of foreign origin if the statutory exception is relied on
Amendment	French amendment signed before the change takes effect	Prior version, translation, consent, and effective date

This approach does not prevent the company from operating in English. It separates the language of management from the language needed to make contractual obligations enforceable in France. It also gives the founder a reliable record if the employee later challenges a bonus, a trial-period renewal, a mobility clause, a confidentiality obligation, or a termination decision.

II. What should a foreign employer do before and after signing?

A. Which English documents remain risky after the contract?

Signing the French contract is necessary, but it is not the end of the language analysis. Article L. 1321-6 of the Labour Code extends the French requirement to the internal rules and to documents that contain obligations for the employee or information needed to perform the work. The official text on Légifrance states, in part, Il en va de même pour tout document comportant des obligations pour le salarié. The article also contains an exception for documents received from abroad or intended for foreign employees.

The exception is narrow and fact-sensitive. It should not be treated as a general “international group” exemption. In Cass. soc., 21 September 2017, no. 16-20.426, the Court accepted that the employer had satisfied the language requirement where the objectives document had been written in French and placed on the employer’s intranet. The Court’s reasoning was that un document fixant les objectifs permettant la détermination de la rémunération variable avait été rédigé en français et diffusé sur le site intranet de l’entreprise. The lesson is straightforward: a later French version can be effective if it is complete, available in time, and capable of informing the employee before the performance obligation is measured.

In Cass. soc., 27 September 2018, no. 17-17.255, the Court dealt with an English retention-bonus annex. The ruling records that le document fixant les conditions nécessaires pour la perception du bonus de rétention, à défaut d’être rédigé en français, est inopposable au salarié. The word “inopposable” matters. It does not necessarily erase the document from existence; it prevents the employer from relying on the document against the employee for the relevant obligation. In a compensation dispute, that can shift the calculation and the evidential burden significantly.

There is also a real distinction between the contract and documents intended for a foreign employee. In Cass. soc., 24 June 2015, no. 14-13.829, the Court applied the exception to English documents concerning variable compensation where the employee was an American citizen. The official decision says that the language rule was not applicable to documents received from abroad or intended for foreigners, and that the employee’s nationality made the relevant factual finding unnecessary. A foreign founder should not assume, however, that the nationality of one employee automatically covers documents distributed to a wider French workforce.

The group should audit at least the following English documents:

• annual objectives and commission or bonus plans;
• equity, stock-option, and long-term-incentive schedules;
• working-time, on-call, remote-work, travel, and expense policies;
• confidentiality, intellectual-property, data-security, and whistleblowing rules;
• employee handbooks, disciplinary rules, health-and-safety instructions, and mandatory notices;
• amendments changing salary, job classification, place of work, or working time;
• letters setting a trial period, renewing it, or changing the employee’s role.

The issue is not limited to documents headed “contract”. A bonus plan can be an accessory to the contract. A security policy can contain obligations. A remote-work policy can define the place and organization of work. An English email may be harmless if it merely coordinates a meeting, but it becomes legally important when it sets a target, changes a right, records consent, or gives an instruction necessary to perform the role.

In Cass. soc., 5 November 2014, no. 13-17.770, the dispute concerned English objectives and the relationship between the employment contract and its performance documents. The case is a useful warning against assuming that a group document is protected merely because it came from a parent company or because the employee is bilingual. The file should show the document’s origin, audience, French availability, and timing. If the employer cannot show those facts, it should prepare a French version instead of building a defence on the exception.

The 2023 decision is even more direct for variable pay. It held that English objectives used to calculate contractual variable remuneration could not be treated as enforceable merely because English was used within the company. The French version should be provided before the performance period or at least before the employee is expected to rely on the objectives. A translation supplied only after a dispute has started is evidence of an attempted correction, not a substitute for timely communication.

The employee’s understanding remains relevant to evidence, but it should be treated as a risk factor rather than a waiver. A French employee may understand English perfectly and still argue that an English document was not opposable. A foreign employee may ask for a translation in a language other than English. The company should therefore ask which language the employee requests, not simply send the group’s preferred English translation.

B. How to correct an English-only contract and organize the first French hire

A foreign company should first identify the actual employer. If a French subsidiary signs the contract, the French subsidiary’s legal name, address, and registration information must appear consistently in the contract, payroll, and corporate records. If a foreign company without a French establishment employs the person directly, the foreign entity must not pretend that a French subsidiary is the employer merely because the employee works with the French team. The group should verify the employer’s registration and the relevant French formalities through the INPI Guichet unique and Registre national des entreprises. INPI is the French National Institute of Industrial Property; in this context, its Guichet unique is the central online channel for company formalities.

The company should then map the contract against the statutory information list. Article L. 1221-5-1 requires the employer to give the employee one or more written documents containing the main information about the employment relationship. The exact provision is available on Légifrance. Article R. 1221-34 gives the detail: parties, workplace, position, start date, fixed-term information where relevant, trial period, training, paid leave, termination procedure, remuneration, working time, collective agreements, and mandatory social-protection schemes. The current article can be checked on Légifrance.

That information should be included in the French contract or in a French information document that is clearly linked to it. The English translation can follow the same structure. Do not leave the salary or the working-time rules only in an English annex. Do not describe a trial period only in a group offer letter. The French file should be complete enough for the employee to understand the relationship without opening a foreign portal.

Before the first day of work, the employer must also address the prior hiring declaration. Article L. 1221-10 states, in the official text, L’embauche d’un salarié ne peut intervenir qu’après déclaration nominative accomplie par l’employeur auprès des organismes de protection sociale désignés à cet effet. The article is available on Légifrance. This DPAE is not replaced by the signed English or French contract. A copy or proof of the declaration should be retained with the employment file. Article L. 1221-11 provides a specific penalty for non-compliance, also visible in the Légifrance section on hiring formalities.

A foreign company without a French establishment may use the URSSAF service for foreign companies, often called Service firmes étrangères, or the TFE, meaning Titre firmes étrangères. The official URSSAF Firmes étrangères page explains that a foreign employer with no French establishment must declare and pay French social contributions where the French social-security legislation applies. The URSSAF TFE page explains that the simplified service can combine the DPAE and the employment contract, but it does not eliminate the obligation to make the contract legally coherent and properly translated.

The contract language and payroll language must be coordinated. French payslips are a separate compliance document. The French tax authority explains on impots.gouv.fr that French or foreign employers paying taxable French salaries must handle the prélèvement à la source, or withholding tax, and that the amounts are generally declared through the DSN, the déclaration sociale nominative or monthly social declaration. A founder should therefore treat the contract, DPAE, payroll, DSN, withholding tax, and social contributions as one onboarding file, even if different advisers or platforms handle each step.

Choice-of-court clauses deserve a specific warning. Article L. 1221-5 of the Labour Code states that a jurisdiction clause in an employment contract is null and ineffective. The rule appears in the official Légifrance section. A foreign template may contain a clause sending all disputes to London, New York, Geneva, or another forum. That clause cannot be assumed to work in a French employment relationship. The applicable-law analysis may involve European conflict-of-law rules and mandatory French protections, but a boilerplate foreign forum clause is not a substitute for that analysis.

The Court of Cassation’s international employment cases reinforce the need for a precise file. The record in Cass. soc., 18 November 2020, no. 19-17.794 concerned foreign employers, a work relationship connected with France, and clauses referring disputes to foreign courts. The case should not be reduced to a simple proposition that every dispute must be heard in France; the facts and the applicable jurisdiction rules matter. The operational point for a founder is narrower: never copy an overseas employment template’s forum clause without checking its effect under French and European employment law.

If an English-only contract has already been signed, the correction should be deliberate. The company should not backdate a French document, silently replace the English terms, or ask the employee to sign a “translation” that actually reduces pay or changes the job. The remediation sequence should be:

1. collect the signed contract, offer letter, annexes, group policies, emails, and evidence of the employee’s language request;
2. identify every term that affects remuneration, working time, place of work, trial period, confidentiality, intellectual property, termination, or post-termination restrictions;
3. prepare a complete French contractual version that preserves the agreed economic terms unless a genuine amendment is separately negotiated;
4. prepare a matching English translation and, where Article L. 1221-3 requires it, the translation requested in the employee’s language;
5. obtain a new signature or amendment without pretending that it cures earlier DPAE, payroll, or notice failures;
6. translate the objectives, bonus plan, and policies before the next performance or compliance period begins;
7. review any past variable-pay calculation and preserve a dated audit trail of the correction.

If the contract contains an English-only CDD, the priority is higher because the written-form rules are stricter. If a bonus was calculated using an English plan, the company should not assume that the payslip or the employee’s silence proves acceptance. The Court of Cassation has repeatedly treated the language of objectives as relevant to enforceability. In a dispute, the employer may need to prove the French version, the date on which it was made available, the employee’s access to it, and the precise calculation used.

The internal owner of the process should also be clear. A foreign founder may sign as a director, but the French company, its payroll provider, its HR contact, and its French counsel should each know who is responsible for the language file. The contract should identify the entity with authority to employ and dismiss. The payroll provider should receive the French version and all applicable collective-agreement information. The employee should have a stable contact for requesting translations or correcting an inconsistency.

For a first French hire, a concise pre-start checklist is useful:

• confirm the employer identity and French registration or foreign-employer registration route;
• select the applicable collective agreement and record its IDCC;
• prepare the French contract and a matched English translation;
• state the job, classification, salary, variable-pay formula, workplace, working time, trial period, leave, benefits, and termination rules;
• attach French versions of all documents that impose obligations or determine compensation;
• make the DPAE before work begins and save the acknowledgment;
• open the URSSAF, payroll, DSN, and withholding-tax channels that apply to the employer;
• give the employee the required written information and maintain a version register.

The checklist is not a substitute for a legal review where the group uses secondment, a foreign payroll, an equity plan, a cross-border work pattern, or a foreign-law template. It is a way to identify the decision points before the first payslip or the first dispute.

Conclusion

A French employee can read and sign an English translation, but a foreign founder should not build the employment relationship on an English-only contract. The safe legal foundation is a complete French contract, accompanied by a reliable English translation and, where requested, a translation in the foreign employee’s own language. The same discipline should cover bonus targets, policies, amendments, and other documents that impose obligations or determine remuneration.

The international group exception is not automatic. It depends on the origin and intended audience of the document, and recent case law shows that the use of English inside the company is not enough. The employer must also complete the DPAE, payroll, social-security, collective-agreement, and withholding-tax formalities. When the employer is a foreign company without a French establishment, URSSAF’s Firmes étrangères and TFE services can simplify administration, but they do not replace a compliant French-language contract.

For a founder who has already used an English template, the right response is a documented correction: audit the documents, preserve the economic terms, produce the French version, translate the supporting documents, and correct payroll or declaration issues separately. That approach gives the company a defensible record while allowing management and the wider group to continue working in English.
