Luxembourg is a holding and structuring jurisdiction. The governance layer of a Luxembourg entity — who is registered as participant, who holds director mandates, what the articles authorise — sits in the Registre de Commerce et des Sociétés and is accessible before a transaction closes. Control, in the sense of who can bind the entity and on what terms, is readable from that record. What the record does not resolve is whether the registered participant acts for its own account or for an undisclosed principal.
A pre-deal review maps the registered governance structure, identifies the statutory limits on management authority, and states explicitly where the chain of control becomes opaque. That boundary is established before payment, not discovered after.

The RCS is the central commercial register for Luxembourg. For a société à responsabilité limitée (Sàrl) or société anonyme (SA) — the two forms most commonly encountered in cross-border transactions — the register holds:
Each of these elements is retrievable as a filed document. The RCS does not produce a structured data export; the record is document-based.
For a transaction review, the articles are the primary governance instrument. They define the scope of management authority, the conditions for share transfer, and any consent or pre-emption mechanisms that bind the parties. A discrepancy between what the articles authorise and what the counterparty represents is itself a finding.

Control in a Luxembourg entity is a function of three overlapping layers: registered ownership, statutory authority, and any shareholder agreement. The first two are in the public record. The third is not.
Registered ownership. For a Sàrl, the list of participants with their respective shares is filed at the RCS and updated on each transfer. The record shows who holds shares at the date of the extract. It does not show whether those shares are held subject to a pledge, a usufruct, or an undisclosed trust arrangement — those instruments may be registered separately or not at all.
Statutory authority. The articles define what the gérant or board can do without shareholder approval. Limits on asset disposal, borrowing thresholds, and reserved decisions are statutory terms. A review of the articles establishes whether the counterparty's management has authority to execute the transaction as described.
Shareholder agreements. Luxembourg law permits shareholder agreements to remain private. They are not filed at the RCS. Their existence cannot be confirmed or excluded from the public record. Where the transaction structure depends on rights created by shareholder agreement, the record establishes only that no contrary provision appears in the articles.
| Layer | Source | Accessible from RCS | Limitation |
|---|---|---|---|
| Registered participants / shareholders | RCS — participant list or share register | Yes | Does not show pledges, usufructs or trust arrangements |
| Director mandates and authority | RCS — filed articles and mandate filings | Yes | Does not show side letters or informal authority |
| Shareholder agreements | Private document | No | Existence cannot be confirmed or excluded |
| Ultimate beneficial owner | Registre des bénéficiaires effectifs (RBE) | Restricted | Access subject to legitimate interest conditions post-CJEU C-37/20 |
| Filed financial statements | RCS — annual accounts | Yes (where filed) | Consolidated group accounts may be filed at parent level only |

Luxembourg law requires most commercial companies to file annual accounts with the RCS. The filing obligation and the level of detail required depend on the size classification of the entity under Luxembourg accounting law.
Small companies may file abbreviated accounts. Micro-entities may file a simplified balance sheet. In both cases, the income statement is not publicly available. A review of filed accounts establishes the balance sheet position and, where filed, the profit and loss account — but the level of disclosure varies by entity size.
Where the Luxembourg entity is a holding company within a larger group, the consolidated accounts may be filed at the level of the ultimate parent, in a different jurisdiction. The Luxembourg entity's standalone accounts show its own assets and liabilities; they do not show the group position unless consolidation is performed at Luxembourg level.
A transaction review identifies which accounts have been filed, for which periods, and what level of detail each filing contains. Gaps in the filing sequence are noted as findings, not assumptions.

Luxembourg established the Registre des bénéficiaires effectifs (RBE) to implement the EU Anti-Money Laundering Directives. The RBE holds information on the ultimate beneficial owners of Luxembourg entities — persons who ultimately own or control the entity above the statutory threshold.
Following the Court of Justice of the European Union judgment in Joined Cases C-37/20 and C-601/20 (WM and Sovim, November 2022), unrestricted public access to beneficial ownership registers was held incompatible with fundamental rights under the EU Charter. Luxembourg suspended general public access to the RBE in response to that judgment.
Access to RBE data is now subject to a demonstration of legitimate interest. The conditions for establishing legitimate interest, the procedure for making a request, and the categories of requestor recognised by the Luxembourg administration are defined by Luxembourg law and administrative practice. Those conditions are assessed on a case-by-case basis.
A pre-deal review maps the registered ownership layer from the RCS and identifies the point at which the chain passes to the RBE or to a non-disclosing intermediate structure. The review states what is established, what requires a legitimate interest access request, and what cannot be resolved from either source.

The RCS establishes the registered governance layer with precision. It does not establish economic reality behind that layer.
Specifically, the following cannot be determined from the RCS alone:
The RBE addresses the last point in part, subject to access conditions described above. The other limitations are structural: they reflect the boundary between what Luxembourg law requires to be filed and what it permits to remain private.
A review that does not state this boundary is incomplete. The ceiling of what the sources allow is stated before payment.
Discrepancies between the RCS record and other available sources are findings in their own right. The most common patterns in Luxembourg transaction reviews:
Articles versus counterparty representations. The articles may impose consent requirements or transfer restrictions that the counterparty's representations do not acknowledge. The filed document controls.
Filed accounts versus management accounts. Where management accounts are provided in a transaction, the filed statutory accounts serve as the reference point for the balance sheet position at the last filed date. Divergence between the two is noted.
Participant list versus group structure representations. Where the counterparty describes a group structure, the participant list at the RCS shows the registered position. Intermediate holding layers not reflected in the counterparty's description are identified.
RBE data versus registered participants. Where access to RBE data is obtained, any divergence between the beneficial owner identified in the RBE and the registered participant at the RCS is a material finding for transaction purposes.

What does a Luxembourg transaction review establish about control? The review establishes who holds registered shares, who holds director mandates, and what the articles authorise management to do without shareholder approval. It identifies any statutory limits on the counterparty's authority to execute the transaction. It does not establish whether registered participants act for their own account or for an undisclosed principal.
Is the RCS a public register? Yes. The RCS is a public register. Extracts and filed documents are available on request. Fees are set by the registrar and published in its official tariff schedule. What the review provides is the retrieved and interpreted record: the registered path, the language, and the identification of what each document establishes and where it stops.
Can the ultimate beneficial owner of a Luxembourg entity be identified? The RBE holds beneficial ownership data. Access is restricted following the CJEU judgment of November 2022. A legitimate interest must be demonstrated. The Extended tier includes an RBE access request where the conditions for legitimate interest are met. The outcome of that request depends on the Luxembourg administration's assessment; it is not guaranteed.
What if the Luxembourg entity is a holding company within a larger group? The RCS record covers the Luxembourg entity. Where the chain of ownership passes through intermediate holding companies in other jurisdictions, the review maps those layers to the extent they are traceable through public registers. The Extended tier includes cross-jurisdictional chain mapping. Layers in non-disclosing jurisdictions are identified as the point where the chain becomes opaque.
How long does the review take? Signal: three to five business days from receipt of the entity identifier. Standard: five to eight business days. Extended: ten to fifteen business days, depending on the outcome of the RBE access request and the complexity of the group structure.
What is not included in any tier? Legal advice on the transaction, qualification of findings as to their legal consequences, representation in negotiations, and advice on enforceability of contractual terms. Those services are provided separately and are not part of this analytical product.
