The Registre de Commerce et des Sociétés (RCS) records the names, mandates, and appointment dates of board members in Luxembourg. Control over a Luxembourg company is exercised through the board — and the board composition is the first layer any cross-border buyer must establish before proceeding.
The angle here is control: who sits on the board, what mandate they hold, and what a shareholder can enforce against that record. The RCS answers the first two questions directly. The third requires a separate layer of analysis that the record alone does not supply.

Luxembourg companies — whether SA, Sàrl, or SE — are required to file board appointments with the RCS. The filing triggers publication in the Recueil Électronique des Sociétés et Associations (RESA), the official electronic gazette.
The RCS extract for a given entity shows:
The extract does not show voting weights among board members, internal delegation arrangements, or side agreements that restrict how a mandate is exercised. Those instruments exist at the level of the articles of association and shareholders' agreements — documents that may or may not be filed.
For an SA (société anonyme), the board structure is typically collegial: decisions require a quorum and majority. For an Sàrl (société à responsabilité limitée), management may be vested in one or more gérants, whose powers can be broad or restricted by the articles. The RCS extract names the gérant but does not reproduce the scope of the mandate as written in the articles.
This distinction matters for control analysis. A gérant named in the RCS may have full autonomous signing authority — or may require co-signature. The extract alone does not resolve this.
The RCS is a Level A source for board composition. That means the record is complete and current at the level of filed information. It does not mean the filed information captures the full control picture.
| Layer | RCS discloses | RCS does not disclose |
|---|---|---|
| Board member names | Yes — by name and mandate | — |
| Appointment and end dates | Yes — as filed | — |
| Mandate type (administrator, gérant, etc.) | Yes | Scope of powers within the mandate |
| Signing authority | Not directly | Restrictions in articles or side agreements |
| Beneficial ownership | No | — |
| Shareholder identity | Partial — for SA, not always; for Sàrl, Gesellschafterliste equivalent filed in some cases | Full chain to UBO |
| Internal governance documents | Articles filed at incorporation; amendments filed if registered | Side agreements, delegation letters |
The articles of association are filed with the RCS at incorporation and must be re-filed on amendment. Reviewing the filed articles alongside the board extract closes part of the gap — but not all of it. Shareholders' agreements are private contracts and are not filed.
A shareholder in a Luxembourg company holds rights defined by the Companies Act of 1915 (as amended) and the articles. The board extract from the RCS establishes who is formally appointed to manage the company. It does not establish what the shareholder can enforce against that appointment.
Enforcement questions — removal procedures, liability of board members, quorum requirements for shareholder resolutions — are answered by the articles and the statute, not by the extract. The extract is the starting point, not the conclusion.
For cross-border buyers, the practical question is whether the board composition on record matches the actual control structure. Discrepancies between the filed board and the operational reality of the company are not visible in the RCS. They surface through financial filings, notarial acts, and — where available — beneficial ownership declarations.
Luxembourg is an EU member state. Following the CJEU judgment in C-37/20 (November 2022), public access to the beneficial ownership register (Registre des bénéficiaires effectifs, RBE) is restricted. Access to the RBE now requires demonstration of a legitimate interest. The RBE is therefore not freely searchable by the general public. [СВЕРИТЬ местным консультантом до публикации]
The RCS shows who is on the board. It does not show who controls the board.
The gap between these two statements is the ceiling of what the record allows. Specifically:
The RCS does not disclose the identity of shareholders who appoint or remove board members, unless those shareholders are themselves registered entities with filed mandates. A natural person holding shares through a Luxembourg holding company, a trust, or a foreign vehicle does not appear in the board extract.
The RBE, which is designed to close this gap, is not publicly accessible following C-37/20. Access requires a legitimate interest declaration and is subject to the registry's assessment. A negative result from a restricted register does not confirm the absence of a beneficial owner — it confirms only that access was not granted or that no filing was made.
The articles of association, filed at the RCS, describe the governance structure as of the last amendment. They do not capture informal arrangements, side letters, or undisclosed delegation of authority.
The ceiling, stated plainly: the record establishes the formal board composition with high reliability. It does not establish the control chain above the board, the scope of individual mandates in practice, or the identity of the persons who placed the board members in their positions.
Luxembourg companies with cross-border structures sometimes show a discrepancy between the board composition in the RCS and the signatories named in transaction documents or banking mandates. This is not necessarily a filing error — it may reflect a delegation of authority that was not registered, or a change of board composition that was filed with a delay.
The RESA publication date and the RCS filing date are not always identical. A board change takes effect on the date of the relevant corporate act, not on the date of publication. For time-sensitive verification, the filing date in the RCS is the operative reference, not the gazette date.
Where the articles on file predate a known corporate event — a merger, a restructuring, a change of shareholder — the filed articles may not reflect the current governance structure. This is a known limitation of any register-based verification and is not specific to Luxembourg.

What does the RCS extract show for a Luxembourg SA? The extract names the members of the board of directors (conseil d'administration), their mandate designations, and the dates of appointment and expiry. It does not show voting weights, internal delegation, or the identity of the shareholders who appointed them.
Is beneficial ownership information available for Luxembourg companies? The Registre des bénéficiaires effectifs (RBE) holds beneficial ownership declarations. Following the CJEU judgment in C-37/20, public access is restricted. Access requires a legitimate interest declaration assessed by the registry. A restricted register is not a blank register — filings exist, but access is conditional. [СВЕРИТЬ местным консультантом до публикации]
Can the articles of association be obtained from the RCS? Yes. Articles filed at incorporation and subsequent amendments are held at the RCS and can be retrieved. The articles describe the governance structure as of the last filed amendment. They do not capture private shareholders' agreements or undisclosed delegation arrangements.
What is the difference between the RCS filing date and the RESA publication date? A corporate act — such as a board appointment — takes effect on the date of the act itself. The RCS filing and the RESA publication follow. For time-sensitive verification, the filing date is the operative reference.
Does a board member listed in the RCS have full signing authority? Not necessarily. The mandate type (administrator, gérant, directeur général) indicates the formal role. The scope of authority within that role is defined by the articles and any internal delegation instruments. The extract names the role; the articles define its limits.
