Control in a Luxembourg company is not always where the register shows it. A shareholder of record may hold shares for another party. A director may act under an undisclosed mandate. The statutory documents filed at the RCS establish the formal structure; they do not establish who gives the instructions. This report maps the distance between the two — before a shareholders agreement is signed.
The angle of this report is control: who holds it, what the official record confirms, and at which point the chain of ownership becomes opaque. That question is answered source by source, step by step, with a fixed price and a stated turnaround at each tier.
The Registre de Commerce et des Sociétés (RCS) is the primary official source for Luxembourg companies. It records the company's legal form, registered seat, articles of association, directors, and — for SARLs — the list of shareholders with their respective share percentages.
The RCS is accessible online. Documents are retrievable per entity. What the register does not contain: the identity of the person who instructed the shareholder of record, the terms of any shareholders agreement filed privately, or the economic beneficiary of a fiduciary arrangement.
For a SARL, the shareholder list (liste des associés) is a filed document. For a SA, bearer shares were abolished; registered shareholders appear in the share register held by the company, not in the RCS. The RCS confirms the existence of the SA and its directors — not its full shareholder composition.

Luxembourg's Registre des Bénéficiaires Effectifs (RBE) was established under the 4th and 5th Anti-Money Laundering Directives. It records the natural persons who ultimately own or control a Luxembourg entity above the statutory threshold.
Following the CJEU judgment in C-37/20 (WM and Sovim, November 2022), unrestricted public access to UBO registers was ruled incompatible with the Charter of Fundamental Rights. Luxembourg restricted general public access accordingly. Third-party access now requires a demonstration of legitimate interest.
What this means in practice: the RBE is not freely queryable by any party that submits a request. The access pathway — the formulation of legitimate interest, the submission procedure, and the response timeline — must be confirmed with local counsel at the time of each extraction. The register exists; the path to it is conditional.

Insolvency proceedings, dissolutions, and certain enforcement actions involving Luxembourg entities are published in the Recueil Électronique des Sociétés et Associations (RESA). RESA is the official electronic gazette for Luxembourg corporate and commercial publications.
A search of RESA establishes whether a dissolution, liquidation, or insolvency publication has been made. A negative result means no such publication was found — it does not confirm that no proceeding has been filed. A filed application that has not yet reached the publication stage will not appear.
The Luxembourg commercial courts (tribunaux d'arrondissement, chambre commerciale) handle insolvency matters. Court-level verification supplements the RESA search where the timeline of a potential proceeding is in question.

Luxembourg SARLs and SAs above certain thresholds are required to file annual accounts with the RCS. Filed accounts are accessible through the RCS portal. The coverage and depth of filed financials depend on the company's size category: small companies file abbreviated accounts; large companies file full consolidated statements.
For holding structures — common in Luxembourg — the filed accounts of the Luxembourg entity may reflect only the holding layer. The operating subsidiaries sit in other jurisdictions and file separately in those jurisdictions. A Luxembourg holding company's accounts do not consolidate the subsidiaries unless the entity is the parent of a group required to consolidate.
This matters for a counterparty assessment: the Luxembourg entity may show minimal activity on its own balance sheet while controlling substantial assets held elsewhere.

Luxembourg is frequently used as an intermediate holding layer. The RCS shows the Luxembourg entity and its directors. The RBE, where accessible, shows the declared beneficial owner. The filed accounts show the Luxembourg layer's financials.
These three sources can produce inconsistent pictures. A declared beneficial owner in the RBE may differ from the economic beneficiary identifiable through the ownership chain of the Luxembourg entity's parent. The filed accounts may show a shareholder loan from an entity whose own ownership is not visible in Luxembourg sources.
Where the sources disagree, the disagreement is reported as a finding — not resolved by assumption. The report states what each source shows, where the figures or names diverge, and what additional source would be needed to close the gap.
The turnaround for a Luxembourg counterparty report depends on two variables: the complexity of the ownership chain and the access pathway to the RBE.
RCS extractions and RESA searches are completed within one to two business days. Filed financial statements are retrieved in the same window where they are available electronically.
The RBE access pathway is the variable that extends the timeline. Where legitimate interest is accepted and the response is prompt, the RBE layer adds two to five business days. Where the access is contested or the entity has applied for restriction of access, the timeline extends further and the outcome is uncertain.
For a straightforward Luxembourg SARL with a single-layer structure and no RBE restriction, the full report is deliverable within five to seven business days. For a multi-layer holding structure with an SA at the top and an RBE access question, ten to fifteen business days is the realistic range.
These are working estimates based on current source response times. They are stated before payment, not after.
The ceiling of what the sources allow is stated here, before any engagement.
The RCS shows the registered structure. It does not show who controls the company in fact. A nominee shareholder arrangement — legal under Luxembourg law — places a name in the register that is not the economic owner. The register does not flag this.
The RBE shows the declared beneficial owner. It does not verify the declaration. A declaration that is inaccurate or outdated remains in the register until corrected. The report states what is declared; it does not certify that the declaration is correct.
Filed accounts show the Luxembourg layer. They do not show what happens below it. A Luxembourg holding company controlling subsidiaries in five jurisdictions files accounts for Luxembourg only. The subsidiaries are visible by name in the accounts — their own financial position is not.
The shareholders agreement itself — the document being signed — is a private contract. It is not filed at the RCS. Its terms are not visible in any official source. The report establishes the official record against which the agreement will operate; it does not review the agreement's terms.
At the point where the official record ends, the report says so explicitly. That statement is part of the product.

What does a counterparty report in Luxembourg cover that a standard company search does not?
A standard company search returns the RCS extract: legal form, directors, and — for a SARL — the shareholder list. A counterparty report adds the beneficial ownership layer (RBE, where accessible), the insolvency and enforcement record (RESA), filed financial statements, and a cross-source discrepancy analysis. The report also states explicitly where the chain of ownership stops and why.
How long does the RBE access take, and what happens if access is refused?
The RBE access pathway requires a demonstration of legitimate interest. Where the access is granted, the response typically arrives within two to five business days. Where the entity has applied for restriction of access — permitted under Luxembourg law in certain circumstances — the access may be refused or delayed. If access is refused, the report records the refusal as a finding and states the basis on which it was refused.
Does the report cover subsidiaries of the Luxembourg entity?
The Signal and Standard tiers cover the Luxembourg entity only. The Extended tier traces the ownership chain across intermediate jurisdictions — meaning the parent entities above the Luxembourg layer and, where relevant, the immediate subsidiary layer. Full coverage of operating subsidiaries in multiple jurisdictions is outside the scope of any single-country report; it is addressed through a multi-jurisdiction engagement.
Can the report be used as a basis for signing the shareholders agreement?
The report establishes the factual record from official sources as of the extraction dates. It does not constitute legal advice and does not contain a legal qualification of the findings. Whether the findings are sufficient to proceed, and what conditions or protections should be reflected in the shareholders agreement, are questions for legal counsel. The report provides the factual layer on which that advice is given.
What if the Luxembourg entity is a SA rather than a SARL?
For a SA, the shareholder list is held in the company's own share register — not in the RCS. The RCS confirms the SA's existence, directors, and statutory documents. The shareholder composition of a SA is not verifiable from the RCS alone. The RBE declaration is the primary official source for the beneficial owner of a SA. This distinction is noted in the report and affects the scope of what the Signal tier can establish.
