Control over a Luxembourg entity is established through a layered reading of at least three official sources. No single register provides a complete picture. The RCS shows who is registered as shareholder and in what proportion. The RBE — subject to access conditions — shows who is declared as ultimate beneficial owner. Filed accounts show whether the financial position matches the corporate narrative. Where these three layers diverge, the divergence itself is a finding.
The angle of this report is control: who formally holds voting rights, who is declared as beneficial owner, and what the shareholder can enforce under Luxembourg law as reflected in filed documents. That is a different question from valuation, tax structuring, or regulatory compliance — those are addressed in separate analytical tracks.
The Registre de Commerce et des Sociétés is the primary public register for Luxembourg commercial entities. It records the legal form, registered address, date of incorporation, names of directors and managers, and — for most entity types — the identity of shareholders with their respective shareholding percentages.
For a société à responsabilité limitée (S.à r.l.), the list of shareholders (associés) is a filed document and is accessible through the RCS portal. For a société anonyme (S.A.), registered shares are recorded; bearer shares were abolished under the law of 28 July 2014, and any residual bearer shares must be held through an approved depositary.
The RCS does not record:
A corporate shareholder in the RCS chain requires a separate inquiry into its own jurisdiction of incorporation. Luxembourg holding structures frequently involve intermediate entities in other EU member states or third countries. Each link in that chain has its own access conditions and its own ceiling.

Luxembourg transposed the Fourth and Fifth Anti-Money Laundering Directives through the law of 13 January 2019, establishing the Registre des bénéficiaires effectifs. Entities subject to the law must declare their ultimate beneficial owners — natural persons holding, directly or indirectly, more than 25% of shares or voting rights, or exercising control by other means.
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 UBO registers was found incompatible with the Charter of Fundamental Rights. Luxembourg subsequently restricted access. As of the verification date, access to RBE data requires demonstration of a legitimate interest or falls within categories of obliged entities and competent authorities.
What this means in practice: a foreign buyer cannot retrieve RBE data through a simple portal search. Access requires a formal request with documented legitimate interest. The outcome of that request is not guaranteed. Where access is granted, the data reflects what the entity itself declared — not what an independent verification would establish.
The RBE declaration is a self-reported filing. It is not cross-checked by the register against underlying corporate documents at the time of filing. Discrepancies between the RBE declaration and the RCS shareholder list are possible and, when found, are material findings.

Luxembourg commercial entities above certain size thresholds are required to deposit annual accounts with the RCS. These accounts are publicly accessible through the RCS portal. The depth of disclosure depends on the entity's classification: large entities file full accounts including notes; small and micro entities file abbreviated versions.
A société de participations financières (SOPARFI) — the most common Luxembourg holding vehicle — files accounts that show the book value of participations, dividend income, and intercompany balances. These figures allow a reader to assess whether the declared ownership structure is consistent with the financial flows recorded.
What filed accounts do not show:
Accounts are filed with a delay. The most recent filed accounts at the time of a report may reflect a financial year that closed twelve to eighteen months earlier. A significant transaction or restructuring completed after the last filing date will not appear.

Luxembourg insolvency proceedings — faillite, concordat, and reorganisation judiciaire — are recorded in the RCS and published in the Recueil électronique des sociétés et associations (RESA). A search of both sources establishes whether a formal insolvency procedure has been opened against the entity.
A negative result in these registers does not exclude the possibility that a petition has been filed but not yet processed, or that informal restructuring is underway outside formal proceedings. It also does not cover insolvency proceedings opened against the entity in another jurisdiction where it operates or holds assets.
Enforcement actions against shares — pledges, seizures, or judicial orders — may be registered separately from the main RCS entry. The completeness of that registration depends on whether the creditor has taken the required registration steps.

The ceiling of what official sources establish in Luxembourg is stated here, before any engagement.
The RCS shows registered ownership as declared at the time of the last filed update. It does not show whether a share transfer agreement has been signed but not yet registered, whether shares are subject to an unregistered pledge, or whether a shareholders agreement modifies the voting rights that appear on the face of the register.
The RBE shows what the entity declared as its beneficial ownership structure. It does not independently verify that declaration. Access to RBE data is subject to a legitimate interest procedure whose outcome is not certain in advance.
Filed accounts show the financial position as of the last deposited period. They do not show transactions completed after that date, and they do not show the economic terms of arrangements structured to remain off-balance-sheet.
The chain of corporate shareholders — a common feature of Luxembourg holding structures — can be traced only as far as each intermediate jurisdiction's register permits. Where an intermediate entity is incorporated in a jurisdiction with limited public disclosure, the chain stops at that point. The report states where the chain stops and why.
No source in Luxembourg discloses the content of a shareholders agreement. The existence of a shareholders agreement can sometimes be inferred from cross-references in filed documents, but its terms remain private unless voluntarily disclosed or ordered by a court.
When the RCS shareholder list, the RBE beneficial ownership declaration, and the filed accounts point in different directions, the divergence is recorded as a finding — not resolved by choosing one source over another.
Common patterns of divergence in Luxembourg holding structures:
Each of these patterns requires a specific note in the report. The report does not resolve the divergence — it records it, identifies the source of each conflicting datum, and states what additional documentation would be required to reconcile the discrepancy.
| Tier | Price | What is included | What is NOT included |
|---|---|---|---|
| Signal | €890 | RCS entity extract: legal form, registered address, directors, statutory managers, shareholder list with percentages; RESA insolvency check; summary of source availability and access conditions | RBE beneficial ownership data; filed accounts review; intermediate holding chain analysis; divergence mapping |
| Standard | €1,900 | All Signal content; RBE access request and result (outcome not guaranteed); most recent filed accounts review; identification of intermediate corporate shareholders with jurisdiction-level access assessment; divergence note where sources conflict | Analysis of intermediate entities outside Luxembourg; legal qualification of findings; shareholders agreement review |
| Extended | €4,200 | All Standard content; tracing of intermediate corporate shareholders through their respective registers (up to two additional jurisdictions); cross-source divergence mapping with source-by-source annotation; written summary of what each source establishes and where each chain stops | Legal advice; shareholders agreement drafting or review; valuation; tax analysis; representation |
The price covers the analytical work described. It does not cover registry fees charged by official sources, which vary by source and access method and are invoiced separately where applicable.
What does a counterparty report cover that a standard company search does not?
A standard company search returns the RCS extract for a single entity. A counterparty report reads that extract against the RBE declaration, the filed accounts, and the insolvency record — and maps where those sources agree and where they diverge. It also identifies the intermediate corporate shareholders in the ownership chain and states the access conditions for each jurisdiction in that chain. The divergence mapping is the analytical layer that a raw extract does not provide.
Can the beneficial owner always be identified?
Not always. The RBE declaration is accessible only where a legitimate interest is demonstrated and the access request is approved. Where access is granted, the data reflects what the entity declared — not an independent verification. Where access is not granted, or where an intermediate entity in the chain is incorporated in a jurisdiction with limited disclosure, the report states that the chain stops at that point and explains why.
How current is the information?
RCS data reflects the state of the register at the date of extraction. Filed accounts reflect the most recently deposited financial year, which may be twelve to eighteen months prior to the extraction date. The report states the extraction date for each source. Events occurring after the last filed update — including share transfers not yet registered — will not appear in the sources.
Does the report cover the content of an existing shareholders agreement?
No. The content of a shareholders agreement is not recorded in any Luxembourg public register. The report can identify whether cross-references to a shareholders agreement appear in filed documents, but it cannot retrieve or review the agreement itself unless it is voluntarily provided.
What happens if the sources conflict?
Conflicting data across sources is recorded as a finding. The report identifies which source shows what, states the date of each datum, and notes what additional documentation would be required to reconcile the discrepancy. The report does not resolve the conflict by choosing one source over another.
Is this report legal advice?
No. This report is a factual compilation from official registers and public sources. It establishes what the record shows. It does not qualify those findings legally, does not advise on the implications for a particular transaction, and does not substitute for legal counsel.
