You live in London, New York, Dubai or Singapore. You have incorporated — or are about to incorporate — a French company, usually a SAS (société par actions simplifiée, the flexible joint-stock company foreigners prefer) or sometimes a SARL (société à responsabilité limitée, the limited liability company with stricter rules). Everything seemed ready: articles of association signed, capital deposited at the bank, file uploaded on the Guichet unique (the single online filing portal run by the INPI, the French intellectual property and business-registration office, through which every creation file must pass since 2023). Then the reply comes back: the greffe — the registry office of the commercial court that keeps the RCS (registre du commerce et des sociétés, the trade and companies register) — refuses to issue your Kbis. The Kbis is the official identity extract of a French company: without it, you cannot prove your company exists, open a normal operating bank account, sign a lease, hire, or invoice with VAT. The reason given is almost always the same: insufficient proof of the registered office (siège social), the legal address where the company is officially housed. This article explains, step by step, how a foreign founder living abroad gives a French company a valid address, gets the Kbis, and chooses between a domiciliation contract and a real Paris lease — with the exact statutes, the case law that decides disputes, and the Paris practice that makes files succeed or fail.
I. How can a foreign founder give a French company a valid registered address and get the Kbis from abroad?
French law starts from a simple principle that surprises many foreign founders: no company is registered without proof that it actually occupies its declared address. The rule is written in black and white for legal entities. Article L123-11 of the Commercial Code provides that “Toute personne morale demandant son immatriculation au registre du commerce et des sociétés doit justifier de la jouissance du ou des locaux où elle installe, seule ou avec d’autres, le siège de l’entreprise, ou, lorsque celui-ci est situé à l’étranger, l’agence, la succursale ou la représentation établie sur le territoire français.” In plain English: every legal person asking for registration must prove it enjoys the use of the premises where it installs its registered office, alone or shared with others — or, where the head office stays abroad, the agency, branch or representative office established on French soil. The same article adds that domiciling a legal person in premises shared by several companies is allowed under conditions set by decree, and that the decree specifies the equipment or services required to prove the reality of the registered office. Two consequences follow for you. First, a mere postal address or a mail-forwarding arrangement with no legal title never suffices: the greffe wants a title of occupation — a lease, a sub-lease authorised by the landlord, a domiciliation contract with an approved provider, or the director’s home used under the conditions the law allows. Second, where several companies share the same premises, the administration checks that the arrangement is real: letter boxes alone do not prove a registered office. The official business-creation portal describes these options in its page on domiciliation of registered persons, which lists the domiciliation contract, collective premises and home-based registration as the three standard routes (see the service-public.fr guide on domiciliation). For completeness, the mirror rule for individuals is Article L123-10 of the Commercial Code: “Les personnes physiques demandant leur immatriculation au registre du commerce et des sociétés ou au registre national des entreprises en tant qu’entreprise du secteur des métiers et de l’artisanat doivent déclarer l’adresse de leur entreprise et en justifier la jouissance.” Individuals must declare their business address and prove they enjoy it. Your company, as a legal person, falls under L123-11, but the logic is identical: declare and prove.
A. What does a domiciliation contract actually buy you — and how do you check the provider is approved?
A domiciliation contract (contrat de domiciliation) is the route most foreign founders take first: you rent your legal address from a domiciliation company that hosts dozens or hundreds of firms in the same building and provides mail handling, meeting rooms and sometimes phone services. It is fast, cheap — typically a few dozen euros per month in Paris, more for a prestigious 8th-arrondissement address — and it can be signed remotely, which matters when you live abroad. But not every provider qualifies, and greffes reject files built on unapproved domiciliaries every week. French law authorises domiciliation in collective premises only under regulated conditions, and the provider must hold a prefectoral approval (agrément préfectoral): a formal authorisation issued by the préfet (the State’s representative in the département) after checking the provider’s premises, honourability and compliance. Before you sign anything from abroad, ask the provider for three documents: a copy of its approval order, proof that it owns the premises or holds a lease authorising domiciliation activity, and a draft contract showing at least the provider’s and your identities, the exact address granted, the services included, and the duration and price. The Paris greffe routinely asks for the contract plus the approval order when the registered office is a domiciliation address, and a missing approval order is one of the most common reasons for a Kbis refusal. Read the contract’s small print with the eyes of someone who will later need to prove reality of occupation: does it give you actual access to premises and services, or only a mail box? The decree contemplated by Article L123-11 requires equipment or services proving the reality of the registered office, so a contract that offers nothing but mail forwarding is fragile. Also check practical points that matter from abroad: how is mail scanned and forwarded, what happens to registered letters (lettres recommandées) and bailiff’s writs, can you book a room for a shareholders’ meeting, and what notice period applies if you leave for a real lease? Keep every exchange in writing. If the greffe questions the address, you will answer with paper, not with explanations. And keep in mind the broader strategy developed in our guide to choosing between a SAS, a SARL, a branch and a subsidiary in France: the registered-office solution must match the vehicle you chose, because a branch (succursale) of a foreign company proves the use of its French premises under the same L123-11 logic, while a subsidiary has its own French seat to justify. Founders who started from the general creation roadmap in setting up a company in France as a foreign founder will recognise this step as the one where files most often stall — and a clean domiciliation file is what gets them unstuck.
One warning specific to regulated-looking offers: some websites sell “Kbis in 48 hours” packages combining a sham address with nominee services. A Kbis obtained on a fictitious address exposes you to radiation d’office — removal of the company from the register by the authorities — and to the far worse finding, in later litigation, that your seat was fictitious or fraudulent. The Court of Cassation protects only real seats: as you will see below, a company keeps the benefit of its published Kbis address only absent proof of a fictitious or fraudulent character. Pay for a real, approved domiciliation, keep the contract and the approval order in your corporate records, and your address will survive scrutiny.
B. Can you register the company at your own Paris home or a friend’s flat instead?
Sometimes the cheapest address is your own: you own or rent a flat in Paris and want the company’s seat there. French law allows it, but within strict limits that foreign founders often discover too late. Article L123-11-1 of the Commercial Code states: “Toute personne morale est autorisée à installer son siège au domicile de son représentant légal et y exercer une activité, sauf dispositions législatives ou stipulations contractuelles contraires.” Every legal person may install its seat at the home of its legal representative and carry on business there, unless legislation or contract says otherwise. That “unless” carries the whole weight of Paris practice. If your lease forbids professional use, if the building’s co-ownership rules (règlement de copropriété) prohibit it, or if planning rules for the address prohibit business activity, the authorisation collapses. Where such an obstacle exists, the same article offers a temporary bridge: the representative may still install the seat at home for a period “ne pouvant ni excéder cinq ans à compter de la création de celle-ci, ni dépasser le terme légal, contractuel ou judiciaire de l’occupation des locaux” — not more than five years from creation, and never beyond the occupant’s own right to the flat. But this bridge has formalities: before filing, the company must notify the landlord, the co-ownership association or the building manager in writing of its intention to use this option, and before the period expires it must report its new address to the greffe, failing which the sanction is radiation d’office, removal from the register. For a founder living abroad who is rarely in Paris, three practical lessons follow. First, never register at a friend’s or relative’s address unless that person is the company’s legal representative (président of the SAS, gérant of the SARL): the text authorises the home of the legal representative, not the home of a helpful acquaintance, and a greffe that spots the mismatch will reject the file. Second, read your own Paris lease and co-ownership rules before filing: most residential leases in Paris prohibit any business use, and many co-ownership rules restrict it; a written refusal from the landlord after the fact can force a costly transfer of seat (transfert de siège). Third, diary the five-year limit from day one and budget for the move to a domiciliation or a lease in time: companies that forget the deadline discover the radiation risk when they can least afford it, during a fundraising or a sale. Where none of these home-based routes works — no compliant home, no willing representative living in France — the domiciliation contract described above is the normal answer, and the commercial lease examined below is the upgrade when the business needs real premises.
II. Should you sign a Paris commercial lease now or stay domiciled a while longer?
At some point a domiciled company needs walls: an office, a shop, a workshop, a storage unit. In France that step usually means entering the world of commercial leases (baux commerciaux), a protective statute that gives the tenant a right to renewal or, failing renewal, an eviction indemnity (indemnité d’éviction) — but only if the tenant qualifies. Foreign founders tend to make two opposite mistakes: signing a nine-year lease they do not understand because “everyone does it”, or working for years from undeclared premises while the Kbis still shows the old domiciliation. Both mistakes cost money. The statute rewards tenants who are properly registered where they operate and punishes those who are not, as the case law below shows. Understanding the scope of the statute, the nine-year commitment with its three-year exits, the short-lease alternative, and the proof the Paris greffe demands turns this step from a gamble into a procedure you control from abroad.
A. What does a nine-year commercial lease really lock you into — and how do the three-year exit and the three-year short lease work?
The scope of the protective statute is the first thing to check, because not every rented room in Paris is a bail commercial. Article L145-1 of the Commercial Code provides that “Les dispositions du présent chapitre s’appliquent aux baux des immeubles ou locaux dans lesquels un fonds est exploité, que ce fonds appartienne, soit à un commerçant ou à un industriel immatriculé au registre du commerce et des sociétés, soit à un chef d’une entreprise du secteur des métiers et de l’artisanat immatriculée au registre national des entreprises” — the chapter applies to leases of buildings or premises in which a business (fonds) is operated, belonging to a trader or industrialist registered with the RCS or to a craft business registered nationally. Two conditions therefore decide everything: a real business operated in the premises, and registration covering that establishment. A foreign company that signs a Paris office lease but never registers the Paris establishment on the RCS, or that uses the rooms only as a mail drop with no activity, may discover at the worst moment — when the landlord refuses renewal — that it never held the protected status it counted on. The leading illustration is a 2020 Court of Cassation ruling: the judges approved a court of appeal that had “retenu à bon droit que le preneur à bail d’un terrain nu sur lequel sont édifiées des constructions ne peut bénéficier du droit au renouvellement du bail que confère le statut des baux commerciaux que s’il remplit les conditions exigées au premier alinéa de l’article L. 145-1-I du code de commerce tenant à son immatriculation et à l’exploitation d’un fonds” and had found that the tenant “n’était pas, au moment de la délivrance du congé, immatriculée pour l’établissement secondaire exploité dans les lieux” — rightly held that a tenant can claim renewal only by meeting the L145-1 conditions of registration and operation of a business, and noted the tenant was not registered for the secondary establishment it operated in the premises when notice was served (Court of Cassation, Third Civil Chamber, 23 January 2020, appeal no. 19-11.215). The lesson for a company run from abroad is blunt: register each Paris establishment promptly, keep the RCS entry aligned with reality, and never let the lease run ahead of the registration. Conversely, parties can contractually extend the protection even where the legal conditions are incomplete. In another 2020 ruling the Court of Cassation quashed an appeal judgment that had denied an eviction indemnity for lack of registration, because the lease stipulated that the parties declared “leur intention expresse de soumettre la présente convention au statut des baux commerciaux, tel qu’il résulte des articles L. 145-1 du code de commerce et des textes subséquents, et ce même si toutes les conditions d’application de ce statut ne sont pas remplies ou ne le sont que pour partie, en sorte qu’il y aura éventuellement extension conventionnelle du champ d’application de ce statut” — their express intention to submit the agreement to the commercial-lease statute even if all its conditions were not met, creating a contractual extension of the statute — so that the landlord had waived reliance on the registration condition (Court of Cassation, Third Civil Chamber, 28 May 2020, appeal no. 19-15.001). If you negotiate such a clause as tenant, it protects you; if you grant it as landlord to your own subsidiary, know what you give away. Either way, have the clause drafted deliberately, never by accident.
The duration rules are the second thing foreign founders misread. Article L145-4 of the Commercial Code opens with the famous line: “La durée du contrat de location ne peut être inférieure à neuf ans.” A commercial lease cannot run for less than nine years. Panic is unnecessary: the same article gives the tenant the right to leave at the end of each three-year period on at least six months’ notice by registered letter or bailiff’s writ, with only narrow exceptions (leases over nine years, single-use buildings, pure offices and certain storage premises may stipulate otherwise). In practice, the Paris market calls this the 3/6/9 lease: nine years on paper, exits at years three and six. The landlord, by contrast, generally cannot end the lease at those dates except to build, rebuild, redevelop or carry out statutory restoration works, and must follow the formal notice regime of Article L145-9. Article L145-9 of the Commercial Code states the baseline: “Par dérogation aux articles 1736 et 1737 du code civil, les baux de locaux soumis au présent chapitre ne cessent que par l’effet d’un congé donné six mois à l’avance ou d’une demande de renouvellement.” Leases under the statute end only by notice given six months ahead or by a renewal request; without notice or request, a written lease continues tacitly past its term, and during that tacit extension notice must still be given six months ahead for the last day of a calendar quarter. For a founder abroad, the message is organisational: diary every deadline twice, send notices by traceable means, and never assume a foreign-style “the lease just ends” logic applies. Finally, where nine years feels too heavy — testing the Paris market with one employee, waiting for a fundraising — the statute offers the short lease (bail dérogatoire). Article L145-5 of the Commercial Code allows parties, when the tenant takes possession, to depart from the statute provided “la durée totale du bail ou des baux successifs ne soit pas supérieure à trois ans” — the total duration of the lease or successive leases does not exceed three years. At expiry the parties may not sign a fresh short lease for the same business in the same premises; if the tenant stays on with the landlord’s tolerance beyond one month after expiry, or if the lease is expressly renewed or a new lease is signed between the same parties for the same premises, a new lease governed by the full statute automatically arises. The short lease also requires an inventory of the premises (état des lieux) at entry and exit, agreed between the parties or drawn up by a bailiff (huissier de justice, now titled commissaire de justice) with costs shared equally where the parties cannot agree. Operators describe the official framework in the business portal’s commercial-lease guide (see the English-language service-public page on commercial leases), and private overviews such as the Bpifrance Création guide on domiciliation companies (see the Bpifrance Création guide on domiciliation providers, the Legalstart guide to the domiciliation contract and the LegalPlace guide to domiciliation companies) confirm the same market practice: short lease to test, 3/6/9 to settle, and always an inventory. Our contribution beyond those guides is the foreign-founder angle they barely cover: registration of each establishment, notices served from abroad with proof of receipt, and the interaction between your lease position and your Kbis address.
B. What proof of premises does the Paris greffe ask for, and how do you unblock a rejected filing from abroad?
The Paris greffe (registry of the Paris commercial court, the busiest in France) applies national law with Parisian thoroughness, and foreign files receive close attention. Expect the filing officer to demand, for the registered-office line of your Guichet unique file: a complete copy of the title of occupation — domiciliation contract plus the provider’s approval order, or full lease plus any landlord authorisation for domiciliation use, or title deed if the company owns — together with proof the title is current (recent rent receipt, landlord certificate, or current domiciliation invoice), and identity documents for the representative. Uploads must be legible, complete and consistent: the address must read identically on every document, the company name must match the draft articles exactly, and dates must cover the filing date. The most frequent rejection reasons for foreign founders are variations between documents (abbreviated vs full address, missing floor or door code), an expired or unsigned contract, a missing approval order, a home-based seat with no landlord notification where the lease visibly forbids business use, and a lease signed by someone without authority to bind the company. When the rejection notice arrives, read it literally: it lists the missing or defective item. Cure precisely that item, re-upload through the Guichet unique, and keep the acknowledgement receipts. Do not refile an identical file in the hope of a kinder reviewer; identical refilings waste weeks and can generate inconsistency flags. If the difficulty is substantive — the landlord refuses the notification, the provider’s approval has lapsed, the premises cannot legally host the activity — change the solution rather than forcing the file: switch providers, renegotiate the lease clause, or move the seat to compliant premises, then file the corrected package once. Throughout, remember what your Kbis address is worth in court. The Court of Cassation held in June 2025 that “une société, tant qu’elle n’a pas fait choix d’un nouveau siège social, est réputée conserver son siège social au lieu fixé par les statuts et publié au registre du commerce, sous réserve de la preuve de son caractère fictif ou frauduleux” — a company that has not chosen a new seat is deemed to keep the seat fixed by its articles and published in the register, subject only to proof that it is fictitious or fraudulent (Court of Cassation, Second Civil Chamber, 12 June 2025, appeal no. 22-24.111). In that case the court of appeal had annulled a procedural filing for a wrong seat address based on a bailiff’s report and the absence of contemporaneous proof of continued domiciliation, even though the address matched the RCS extract; the Court of Cassation quashed that reasoning because the challengers had not proved the fictitious or fraudulent character of the published seat. For you, the teaching runs both ways. Offensively, opponents cannot brush aside your Kbis address with a mere bailiff’s non-finding or an outdated invoice: they must prove fiction or fraud. Defensively, keep your seat real and your proof current — valid contract, paid invoices, mail actually collected, activity genuinely traceable — so that no challenger can ever assemble that proof against you. Paris-specific discipline completes the picture: commercial court mail, tax mail from the SIE (service des impôts des entreprises, the corporate tax office) and URSSAF letters (URSSAF, the body collecting social contributions) all go to the registered office; from abroad, organise daily scanning with your domiciliataire or your Paris contact, because a missed six-month lease notice, a missed tax deadline or a missed court summons can cost more than a year of rent. Announce the seat consistently everywhere — BODACC (Bulletin officiel des annonces civiles et commerciales, the gazette publishing company registrations), bank, insurer, VAT file — since divergent addresses across registers invite questions. And when the company outgrows domiciliation, file the transfer of seat promptly: the Kbis must mirror reality at all times, and counterparties check it.
Conclusion
A foreign founder running a French company from abroad does not need a Paris office on day one, but does need a Paris address that proves itself. Start with the vehicle decision — our guide to choosing between a SAS, a SARL, a branch and a subsidiary sets that frame — then secure the seat: an approved domiciliation contract with its approval order in hand, or the representative’s compliant home with written landlord notification and the five-year deadline diarised. When activity demands walls, choose deliberately between the three-year short lease that tests the market and the nine-year lease with its three-year exits, register each establishment so the renewal right actually exists, and keep notices and inventories traceable from abroad. Build the Guichet unique file as a proof bundle where every address matches, cure rejections literally rather than refiling identically, and keep the seat real so the Kbis presumption works for you and never against you. The founders who get their Kbis in one filing round are rarely the luckiest; they are the ones whose address file was already court-proof before the greffe opened it.
