Who controls a Luxembourg company is not always the person named in the articles. The RCS names the registered shareholders and managers. The RBE holds the beneficial ownership layer. After CJEU C-37/20, access to the RBE requires a demonstrated legitimate interest. A buyer signing a shareholders agreement without resolving that gap is contracting on incomplete information about the control structure.
This page describes what each official source covers, what the access conditions are, and where the chain of information ends — before any payment is made.
What the RCS reveals about the corporate structure
The Registre de Commerce et des Sociétés is the statutory registry for all commercial entities incorporated in Luxembourg. It is maintained by the Luxembourg Business Registers (LBR) authority.
A standard RCS extract for a SARL or SA shows:
- Corporate name, registered address, and statutory seat
- Date of incorporation and duration of the entity
- Names and functions of managers (gérants) or directors (administrateurs)
- Registered share capital and, for a SARL, the identity of shareholders with their nominal holdings
- Filed amendments to articles of association
- Any registered pledges over shares (nantissements)
For a SARL, the shareholder list is part of the registered articles and is therefore publicly accessible. For an SA, bearer shares were abolished by the law of 28 July 2014; all shares are now registered, but the shareholder register is held by the company itself and is not deposited at the RCS.
This distinction matters for a buyer. A SARL structure gives direct access to the nominal shareholder layer. An SA structure does not.

The beneficial ownership layer and the RBE access condition
Luxembourg transposed the Fourth and Fifth Anti-Money Laundering Directives through the law of 13 January 2019, establishing the Registre des bénéficiaires effectifs. Every Luxembourg entity must file the identity of its ultimate beneficial owner — defined as any natural person holding, directly or indirectly, more than 25% of shares or voting rights, or exercising control by other means.
Following the CJEU judgment in Joined Cases C-37/20 and C-601/20 (WM and Sovim, November 2022), public access to the RBE was suspended. Access is now conditional on demonstrating a legitimate interest. The Luxembourg Administration de l'Enregistrement, des Domaines et de la TVA (AED) administers access requests.
What this means in practice:
- A foreign buyer without a pre-existing legal relationship to the entity faces a procedural barrier at the RBE.
- The access request must be submitted in French or Luxembourgish, with supporting documentation.
- Processing time is not fixed by statute and varies in practice.
- Denial of access is possible where the beneficial owner invokes a risk to personal safety or privacy.
The RCS alone does not substitute for the RBE. A nominee shareholder arrangement — lawful under Luxembourg law — will show a fiduciary as the registered holder. The RCS will not flag this. The RBE is the only official source that names the natural person behind the structure.

Directors, managers, and signatory authority
For a SARL, the gérant (manager) is named in the articles and in the RCS. The gérant's authority to bind the company is defined by the articles and by the law of 10 August 1915 on commercial companies (as amended). Third parties dealing with the company in good faith are protected against restrictions on the gérant's authority that are not published.
For an SA, the board of directors (conseil d'administration) or, under the 2016 reform, a single director in certain cases, holds management authority. The articles may delegate daily management to an administrateur-délégué. That delegation must be filed at the RCS to be opposable to third parties.
A buyers' review before signing a shareholders agreement should establish:
- Whether the gérant or director named in the RCS is still in office (the RCS shows the last filed update, not real-time status)
- Whether any restrictions on authority are filed
- Whether the signatory to the shareholders agreement has the capacity to bind the entity
The RCS does not provide real-time data. A filing lag between a board resolution and its registration at the RCS is normal. The extract reflects the state of the register at the moment of retrieval, not the current corporate reality.

Filed financial statements and the RESA
Luxembourg companies above certain size thresholds are required to file annual accounts with the RCS. Filed accounts are published in the Recueil Électronique des Sociétés et Associations (RESA), the official electronic gazette.
The filing obligation applies to:
- SAs and SARLs exceeding two of three thresholds: balance sheet total above a statutory figure, net turnover above a statutory figure, or average headcount above 50
- Holding companies and SOPARFIs are subject to their own filing rules depending on structure
Small companies may file abbreviated accounts. Micro-entities may benefit from further exemptions. A company that qualifies for an exemption may have no publicly available financial data at all.
Where accounts are filed, they show the balance sheet, profit and loss account, and notes. They do not show intra-group loan terms, management fee arrangements, or the economic substance of transactions between related parties.

Insolvency and judicial proceedings
Luxembourg insolvency proceedings — faillite, gestion contrôlée (now replaced by the restructuring regime under the law of 7 August 2023), and sursis de paiement — are published in the RESA and in the Mémorial C (now integrated into the RESA). The commercial court (Tribunal d'Arrondissement, chambre commerciale) handles insolvency matters.
A search of the RESA for insolvency notices is the standard first step. However:
- A petition filed but not yet adjudicated will not appear in the RESA.
- Voluntary restructuring negotiations under the 2023 law may be confidential at the pre-judicial stage.
- Cross-border insolvency proceedings opened in another EU member state may not be reflected in Luxembourg sources until notification is received and published.
A negative result in the RESA does not confirm the absence of a pending petition.

Pledges over shares and security interests
Luxembourg law permits the pledging of shares in a SARL or SA as security. A pledge (nantissement) over SARL shares must be registered at the RCS to be opposable to third parties. An SA share pledge is governed by the law of 5 August 2005 on financial collateral arrangements and is not necessarily filed at the RCS.
A buyer reviewing a SARL will find registered pledges in the RCS extract. A buyer reviewing an SA will not find share pledges in the RCS and must request confirmation from the company or its registrar.
This asymmetry is a structural feature of Luxembourg law, not a gap in the registry. It must be accounted for in any pre-signing review.

The limit of what the sources allow
The RCS shows the registered layer. It does not show who instructed the registered shareholder to hold the shares, on what terms, or for whose economic benefit. That information sits in the RBE — and the RBE is not publicly accessible following CJEU C-37/20.
The ceiling of what the sources allow is stated before payment. Specifically:
- For a SARL: the nominal shareholder layer is visible. The beneficial owner layer requires an RBE access request with demonstrated legitimate interest. Denial is possible.
- For an SA: the shareholder register is held by the company and is not in the RCS. The beneficial owner layer is in the RBE under the same access conditions.
- For any structure using a fiduciary or nominee: the RCS will show the nominee. The RBE will show the beneficial owner — if access is granted.
- For holding chains with Luxembourg as an intermediate layer: the review establishes the Luxembourg node. Upstream layers in other jurisdictions require separate requests to those jurisdictions' registries.
Where the chain ends is named explicitly in the report. The report does not speculate beyond what the sources confirm.
Where the sources disagree
A discrepancy between the RCS shareholder list and the RBE beneficial ownership filing is itself a finding. It may indicate a nominee arrangement, a recent transfer not yet reflected in one register, or a filing error. The report records the discrepancy and identifies which source was retrieved on which date. It does not resolve the discrepancy by inference.
A discrepancy between filed financial statements and the capital structure shown in the RCS — for example, a significant increase in net assets without a corresponding capital increase — is noted and sourced. The report does not explain the discrepancy; it records it.
FAQ
What is the difference between the RCS and the RBE in Luxembourg? The RCS records the legal structure of the entity: its name, registered address, directors, and — for a SARL — its registered shareholders. The RBE records the natural persons who ultimately own or control the entity, regardless of the legal structure used to hold that ownership. The two registers are maintained by different authorities and are subject to different access conditions.
Can a foreign buyer access the Luxembourg RBE directly? Access to the RBE requires a demonstrated legitimate interest following the CJEU judgment of November 2022. A foreign buyer without a pre-existing legal relationship to the entity must submit a formal request to the AED in French or Luxembourgish with supporting documentation. The outcome is not guaranteed. The Extended tier of this report includes preparation and submission of that request.
Does a negative insolvency search in the RESA confirm the company is solvent? No. A negative result confirms that no insolvency judgment or published notice appears in the RESA at the date of retrieval. A petition filed but not yet adjudicated, or a confidential pre-judicial restructuring, will not appear. The report states the date of retrieval and the scope of the search.
What does the report cover for an SA structure where the shareholder register is not public? For an SA, the report covers the RCS extract (directors, capital, registered address), the RESA insolvency check, the RBE access request (Extended tier), and the review of filed financial statements where available. The shareholder register held by the company is not accessible through official registries and is outside the scope of the report.
How long does an RBE access request take? Processing time is not fixed by statute. In practice, it varies. The Extended tier includes follow-up with the AED. The report notes the submission date and the response received. If no response is received within the report period, that fact is recorded.
