What is a Company Name Change for a SASU in France?
Changing your SASU’s corporate name (“dénomination sociale”) means officially modifying the name by which your company operates and appears in all legal, tax, and commercial documents.
This modification must be decided by the sole shareholder through a formal decision and must be registered with the Commercial Court Registry after publication in a legal gazette.
A company name change is often necessary when a business evolves, rebrands, expands its activities, or simply wants to modernize its image. This change has no effect on the company’s legal personality or existing contracts, but it must follow specific legal formalities to remain valid and enforceable.
Main Advantages :
Fresh brand identity: adapt your SASU’s image to new markets or products.
Continuity of contracts: all rights and obligations remain intact — only the name changes.
Flexible process: one shareholder can approve and sign all required resolutions.
Official recognition: the new name is legally registered and published for third-party notice.
Compliant update: ensures coherence between your company’s articles, Kbis, and tax or banking records.
Changing your SASU’s name can refresh your business identity while maintaining its legal structure and continuity.

Understanding the Change of Company Name in a French SASU
Can a SASU freely change its company name (“dénomination sociale”) in France?
Yes. A Société par Actions Simplifiée Unipersonnelle (SASU) may change its name at any time through a decision of its sole shareholder (“associé unique”).
This operation, although straightforward, is a statutory modification of the company and must therefore follow strict legal formalities.
The change takes effect only after three steps:
- A formal decision by the sole shareholder recorded in writing;
- An amendment of the bylaws (articles of association);
- Registration with the Commercial Court Registry (Registre du commerce et des sociétés – RCS), preceded by publication in a legal gazette.
Until these steps are completed, the former company name remains the only legally valid one for contracts, invoices, and filings.
What are the legal steps to change a SASU’s name?
The change follows a five-stage process:
- Drafting the shareholder’s decision
A written resolution is prepared, stating the old and new names and the amendment to the bylaws. - Updating the bylaws
The article referring to the “dénomination sociale” is rewritten to reflect the new name. - Publication in a legal gazette
A mandatory notice is published in a journal d’annonces légales (JAL) within the department of the registered office. - Filing with the Commercial Court Registry
The filing includes: the shareholder’s decision, updated bylaws, publication certificate, M2 form, and payment of registry fees.
Issuance of the updated Kbis extract
The RCS registers the modification and issues a new Kbis showing the updated company name.
Does the name change affect contracts or liabilities?
No. A change of corporate name does not create a new legal entity.
All prior contracts, rights, and obligations remain attached to the company identified by its SIREN number.
In practice:
- Ongoing contracts remain in force automatically;
- The company should notify partners, suppliers, and clients of the new name;
- Documents such as letterhead, invoices, and bank records must be updated promptly.
Can a foreign shareholder change the SASU name from abroad?
Yes. A foreign shareholder or parent company can fully carry out the name-change process remotely.
Electronic signature and digital filings are legally recognized by French registries.
Only notarized or certified identification documents may be required in certain cases (especially for non-EU shareholders).
If the SASU’s president resides abroad, they may delegate signature authority to a local representative or French counsel via a special power of attorney.
What happens if the company fails to register the new name?
Failure to register the name change renders it unenforceable against third parties.
The company would remain bound by its former name, and any contracts or invoices issued under the unregistered name could be deemed irregular.
Additionally, the RCS may issue a warning or, in persistent cases, initiate administrative dissolution proceedings for non-compliance.
Who decides and signs when there is only one shareholder?
In a SASU, the sole shareholder exercises all powers normally reserved for a general meeting.
Therefore, the shareholder alone:
- approves the name change,
- amends the relevant article in the bylaws (usually Article 3 “Dénomination sociale”), and
- authorizes the president to carry out registration and publication formalities.
The decision is recorded in a written resolution (“décision de l’associé unique”), which must include the new name, the date of effect, and authorization for filing.
If the shareholder and the president are the same person, they sign in both capacities.
Does the company need to justify the new name before adopting it?
Yes, the new name must comply with French company-naming rules:
- It must be available (not already registered or protected as a trademark or company name);
- It must not mislead the public (for instance, suggesting a regulated activity without authorization);
- It must respect public order and good morals;
- It must be written in Roman characters and use the Latin alphabet for registration purposes.
A name-availability search is strongly recommended — both in the Infogreffe company register and the INPI trademark database — to avoid litigation or forced name changes later.
Can the company continue operating during the procedure?
Yes. The company continues all activities uninterrupted under its existing registration number (SIREN).
Contracts, VAT numbers, and bank accounts remain valid.
However, it must avoid using the new name publicly (on invoices, websites, or commercial materials) until the Kbis has been updated — otherwise, third parties may challenge its validity.
How much does it cost to change a SASU name?
The total cost includes:
- Legal Gazette publication: approximately €150–€200 depending on the department;
- Registry amendment fees: around €70–€80;
- Professional fees: if handled by a lawyer or paralegal firm.
When managed by FrenchCo.lawyer, the flat legal fee starts from €599 excl. taxes, plus mandatory publication and registry costs.
This covers all drafting, filing, and official follow-up until delivery of the new Kbis extract.
What documents are required to file the change?
To complete the formalities, the following are needed:
- Decision of the sole shareholder approving the new name;
- Updated articles of association;
- Legal gazette publication certificate;
- Completed M2 registry form;
- Proof of identity of the president;
- Payment receipt of registry fees.
These documents must be filed electronically on the official Guichet unique or directly at the Greffe du Tribunal de Commerce.
