Hosting a single-member company in Monaco: what does the law say?
Creating a single-member company in Monaco (SURL) is an attractive solution for any entrepreneur wishing to launch a business with flexibility and legal certainty. But beyond the legal form, the question of the registered office address quickly arises: can you register your business at home? What should you do once the legal deadline has expired? And above all, how can you get set up without wasting time?
CATS Business Center, a recognized player in Monaco for over 30 years, supports you every step of the way. Here’s what you need to know.
🔎 Since the legislative reform of 2025, the creation of a Single-Member Limited Liability Company (SURL) has been governed by specific procedures. Whether you are a Monegasque or foreign national, you will need to submit an application to the Economic Development Department (DDE) in order to obtain either a license to operate or to make a declaration of operation, depending on your situation.

What is a single-member company?
A SURL (Société Unipersonnelle à Responsabilité Limitée) is a type of single-member company, derived from the SARL, which allows an individual entrepreneur—whether Monegasque or foreign—to carry out a commercial activity in their own name, while benefiting from a separate legal structure. Its creation follows a specific regulatory framework, defined by Law No. 1.573 of April 8, 2025, and the official procedure of the Directorate of Economic Development (DDE). It allows for independent business activity while limiting financial risks. Thanks to the legislative reform of April 2025, it now enjoys fully recognized status in the Monegasque Commercial Code.
A sole proprietor can thus have an official structure, separate from their person, with all the advantages of a company. For those who prefer an even simpler form, certain activities in Monaco can also be registered under a personal name, particularly in the crafts, liberal professions, or trade sectors.
Can a single-member company be domiciled at one’s home in Monaco?
✅ Yes, but under certain conditions: these vary depending on the type of accommodation of the manager and the composition of the share capital.

FAQ on single-member companies in the Principality of Monaco
What is a SURL in Monaco?
A SURL (single-member limited liability company) is a form derived from an LLC, designed for individual entrepreneurs who want to start their own business independently. It allows them to carry out an independent activity while limiting financial risks.
Its legal framework was consolidated by Law No. 1.573 of April 8, 2025, on the modernization of company law, which is based in particular on Bill No. 256, allowing for the official integration of the SURL into the Monegasque Commercial Code.
A sole proprietor can thus have a fully recognized legal structure, separate from their person, and enjoy all the advantages associated with company status.
Can you host a SURL at home in Monaco?
Yes, for up to two years, unless you are Monegasque and live in state-owned accommodation, in which case the duration is unlimited.
Is it possible to convert a SURL into a SARL?
Yes. Law No. 1.573 of April 8, 2025 provides that the sole partner may decide to open up the capital to other persons in order to convert the SURL into a SARL.
No change in corporate purpose or new administrative authorization is required if the activity remains the same. This flexibility is one of the great advantages of registering in Monaco.
Are the rules the same for SARLs?
Yes. SURLs and SARLs are subject to the same conditions for accommodation at the manager’s home.
What other forms of business are possible?
In addition to SURLs and SARLs, certain professions can be practiced under a personal name, within a regulated framework, benefiting from a status recognized by the authorities.
What are the advantages of Monaco for entrepreneurs?
- Legal stability
- Favorable tax environment
- Unparalleled quality of life
- Access to an international business network
What are the administrative procedures for setting up a SURL in Monaco?
The procedure depends on the nationality of the sole partner and manager, as well as the nature of the business. A Monegasque national can simply submit a declaration of business activity for an unregulated business. In other cases (foreign partner or manager, regulated business), an application for a business license is required. The application must include, among other things, the articles of association, proof of nationality, proof of deposit of funds, and documents relating to the registered address.
