Corporate Names in France: Rules, Legal Risks, and Best Practices

Introduction

Choosing a company name in France — the dénomination sociale — is far more than a creative exercise in branding. It is a legal requirement anchored in the French Commercial Code and one of the mandatory elements of a company’s articles of association. Once chosen, the name is filed with the Commercial and Companies Register (Registre du commerce et des sociétés or RCS) and becomes the primary identifier of the company in all legal, administrative, and commercial contexts.

While entrepreneurs enjoy freedom in naming their business, the law imposes specific restrictions. Names must use permissible characters, be clear and unambiguous, respect public order, and avoid infringing the rights of third parties. Moreover, the company name interacts with other identifiers such as trademarks, trade names, and domain names, raising potential risks of disputes.

This article offers a detailed exploration of the French legal framework governing company names, particularly in the case of SARLs (sociétés à responsabilité limitée), while also touching on SAS and SA. We will examine the statutory rules, case law, administrative practice, and practical recommendations that businesses should follow to avoid pitfalls.

1. The Legal Nature of a Corporate Name

Article L.223-1 of the Commercial Code requires every SARL to have a corporate name included in its statutes. This designation can take various forms. Some companies choose descriptive names closely linked to their activity, such as “La Carrosserie Automobile Plastique.” Others prefer fanciful names, such as “Carautoplastique,” which have no direct relation to the corporate purpose but are distinctive and easier to brand. Finally, it is common to incorporate the name of one or more partners, as in “La Carrosserie Automobile Durand.”

The courts have confirmed that these options are consistent with the law. For instance, the Paris Court of Appeal ruled in 1999 that the name “B… & Associés” was valid, provided it was followed by the words “société à responsabilité limitée.” This shows that the law seeks a balance between entrepreneurial freedom and transparency toward third parties.

2. Restrictions on Company Names in France

Despite the wide discretion available to entrepreneurs, registrars at the RCS may refuse to register names that do not comply with statutory requirements. The first restriction concerns the composition of the name. It must be formed using only Latin alphabet letters and Arabic or Roman numerals. Symbols such as the hash sign (#), dollar or euro signs, slashes, or asterisks are in principle prohibited. An exception was carved out in 2001, when the Paris Court of Appeal accepted the use of slashes and asterisks, contrary to the CCRCS’s guidelines.

A second restriction concerns clarity. A name must be determined with certainty and not lead to ambiguity. The registrar rejected “X3” on the grounds that “X” could be read either as a letter or as the Roman numeral for ten, while the digit “3” could represent a number, a multiplier, or an exponent.

Finally, corporate names must comply with public order and morality. The CCRCS issued an opinion in 2013 reminding that names contrary to statutory provisions or good morals cannot be accepted.

3. Obligation to Mention the Corporate Form Together with the Corporate Name

French law requires companies to display their legal form alongside their chosen name. For SARLs, this means the words “société à responsabilité limitée” or the abbreviation “SARL” must immediately precede or follow the corporate name, accompanied by the amount of share capital. This requirement does not mean that the acronym “SARL” must be included inside the corporate name itself. Rather, it must always accompany the name in official usage — for example on invoices, contracts, and letterheads.

The rationale is simple: transparency. Third parties must know at a glance the type of company they are dealing with and the scope of liability of its shareholders.

4. The Use of Symbols and Abbreviations in Corporate Names

The growing influence of digital culture has pushed courts to address the use of modern symbols in corporate names. The “@” sign, or arobase, has been accepted as equivalent to the letter “a” for the purposes of alphabetical classification in the RCS. In 2003, the Caen Court of Appeal confirmed this interpretation but also emphasized that the K-bis extract must reproduce the actual name faithfully, without substituting or modifying the symbol. The Ministry of Justice supported this interpretation in a parliamentary response in 2008.

Acronyms, or sigles, are also subject to specific rules. If the articles of association explicitly mention an abbreviation — for example “Dupont Durand Martin par abréviation DDM” — then the acronym must be declared as a sigle. Where the corporate name incorporates initials, such as “Dupont Durand Martin DDM,” the initials qualify as a sigle only if they are declared at the time of registration. The acronym is then declared to the RCS and published in a journal of legal notices.

In contrast, the use of the euro symbol (€) has been expressly prohibited. The RCS does not recognize it as a valid letter of the alphabet.

5. Corporate Name, Trade Name, and Trademark in France

A company’s dénomination sociale should not be confused with its trade name (enseigne) or trademarks. The corporate name is unique and fixed in the company’s statutes. By contrast, a business may have multiple trade names associated with its establishments, and these can be changed without modifying the registered corporate name.

Trademarks constitute a separate category of intellectual property. The law prohibits the use of a corporate name that infringes a trademark. Two situations are particularly risky:

• Where the company name is identical to a registered trademark covering identical goods or services.
  
• Where the company name is identical or similar to a trademark and creates a likelihood of confusion, including an association between the two.
  

Adopting a name in violation of these principles exposes the company to legal action for infringement and unfair competition.

6. The Use of Patronymic Names as Corporate Names in France

The use of surnames in company names raises delicate questions. French law traditionally treats surnames as inalienable. However, case law has consistently allowed them to be used as corporate names when incorporated into the articles of association. Once included, the surname becomes a distinctive sign of the legal entity and a component of its intangible assets.

The use of a surname nevertheless requires consent, especially if it belongs to someone not actively involved in the company. In 2003, the Court of Cassation held that the consent of a founder to the use of his surname as a company name did not give the company the right to register that surname as a trademark for identical products or services without explicit or tacit waiver. In another case in 2011, the Court ruled that a surname identical to an existing trademark could be used in a corporate name if the person concerned exercised control functions in the company.

Case law also shows that companies can act against bad faith. In 2013, the Court of Cassation recognized that a company could prohibit a competitor from using the same surname in its corporate name if the latter had registered a trademark in bad faith. At the same time, the law maintains a safeguard: an individual cannot be prevented from using his or her own surname in commerce, provided it is done in accordance with fair practices.

7. Prior Rights and Risk of Confusion in Corporate Names

The law provides that ownership of a corporate name arises not from registration but from the first public use. This principle means that conflicts often hinge on the extent of the company’s commercial presence and the potential for confusion among the public.

The courts frequently sanction companies whose names are too similar to those of competitors in the same sector. In 2004, the Court of Cassation confirmed that two companies in the IT sector with similar names risked creating confusion, and one was ordered to change its name.

To avoid such disputes, entrepreneurs are strongly encouraged to conduct prior rights searches. The INPI (Institut national de la propriété industrielle) offers tools for this purpose. The free DATA INPI database provides access to company names, while paid services offer more thorough searches for trademarks and corporate names. Industrial property attorneys can provide even deeper clearance investigations.

Registering a corporate name as a trademark offers stronger protection, enabling the owner to bring infringement actions. However, fraudulent filings are closely monitored. In 2002, the Court of Cassation annulled a trademark registered by a company whose managers knew the same name had already been adopted by a company in formation.

8. Domain Names and Online Identity

In the digital economy, corporate names must also be protected online. Securing a domain name corresponding to the company name is now considered an essential step.

French law allows companies and individuals in France or the European Union to register “.fr” domain names, managed by AFNIC. “.eu” domains are open to all EU residents or nationals, while “.com” domains have no restrictions beyond the “first come, first served” principle.

Conflicts frequently arise when third parties register domain names identical to corporate names. French courts recognize that, despite the priority rule, domain names registered in bad faith may be cancelled, especially when the registration amounts to fraud, parasitism, or unfair competition.

Companies also have the option to declare their domain names at the RCS. This is not compulsory, but it strengthens transparency. Declaring a domain name implies that the site is already active or about to be launched. False declarations may result in fines of up to €4,500 and imprisonment for six months.

9. Practical Recommendations When Choosing a Corporate Name

When selecting a company name in France, businesses should proceed with caution. The name should be distinctive and commercially appealing, but it must also comply with statutory requirements and avoid conflicts with existing rights.

The process should begin with a legal compliance check, ensuring that prohibited characters are avoided and that the name is sufficiently precise. A thorough search of INPI databases should then be conducted. If the company intends to build a strong brand identity, registering the name as a trademark is highly advisable. At the same time, domain names corresponding to the corporate name should be secured promptly.

Special care should be taken when using surnames, as these raise issues of consent and potential disputes in the event of sale or transfer of control. Acronyms and abbreviations should be declared correctly, and companies should ensure that their legal form is consistently indicated in official usage.

In short, the naming process should not be treated lightly. It is a legal act with significant commercial implications, and missteps can lead to costly litigation.

Conclusion

The choice of a corporate name in France is more than a branding decision. It is a statutory requirement with important legal consequences. While companies enjoy flexibility, they must navigate a framework of restrictions designed to protect public order, clarity, and third-party rights.

A company name interacts with trademarks, trade names, and domain names, creating potential areas of conflict. For this reason, businesses must conduct prior rights searches, secure domain names, and consider trademark registration.
