Before any shareholders agreement is signed, the question is not whether the counterparty exists — it is who controls it and what that control structure looks like on paper. In Luxembourg, the answer comes from layered official sources, each with its own access condition and its own ceiling.
The control angle matters here specifically. A Luxembourg holding company may have a clean RCS entry and a director of record who is a professional nominee. The shareholder of record may itself be a holding vehicle in another jurisdiction. The sources described below establish what is visible at each layer — and name the layer where the chain stops.
What the RCS/LBR shows about a Luxembourg counterparty
The Registre de Commerce et des Sociétés (RCS), administered by the Luxembourg Business Registers (LBR), is the primary official source for company data in Luxembourg.
For a standard société à responsabilité limitée (Sàrl) or société anonyme (SA), the register contains:
- The company's legal name, registered address, and legal form
- The date of incorporation and the registered number
- Names of directors, managers, and authorised signatories
- Filed articles of association and any amendments
- Annual accounts, where filing is required and completed
Most documents in the register are available as PDF downloads at no charge through the LBR portal. This is a public register. What a foreign requester is paying for — when engaging a firm to retrieve and analyse these records — is the removed path: identifying the correct national identifier, navigating the portal in Luxembourgish, French, or German, and assembling the filing history into a readable sequence.
This register is public and free of charge. What you are paying for is the removed path: registration, national identifier, language, electronic signature, declaration of legitimate interest.
The shareholder layer: what is filed and what is not
Luxembourg law requires that certain changes in shareholding be filed with the RCS. For an Sàrl, the shareholder register is a company document — not a public register entry in the same sense as the directors list. Filed versions of the shareholder register may appear in the document archive, but completeness depends on filing history and the date of the most recent amendment.
For an SA, bearer shares were abolished under the 2014 law implementing FATF recommendations. Registered shares are the norm. The shareholder register is maintained at the company's registered office and is not publicly accessible through the RCS.
This distinction matters before signing a shareholders agreement. The person or entity appearing as a counterparty may hold shares directly or through an intermediate vehicle. The RCS establishes the first layer. It does not automatically establish the second.
The UBO register: access conditions after CJEU C-37/20
Luxembourg transposed the Fifth Anti-Money Laundering Directive and established a beneficial ownership register (Registre des bénéficiaires effectifs, RBE). Following the Court of Justice of the European Union ruling in joined cases C-37/20 and C-601/20 (November 2022), Luxembourg restricted public access to the RBE.
Access to the RBE is now limited to competent authorities, obliged entities under AML law, and persons or organisations demonstrating a legitimate interest. A foreign buyer conducting pre-contractual due diligence may qualify under the legitimate interest ground, but the access procedure requires a formal request and is subject to assessment.
The ceiling here is structural: even with access, the RBE shows the declared beneficial owner — the person who filed the declaration. It does not independently verify the accuracy of that declaration against the underlying ownership chain.
Directors and managers: what the register confirms
The RCS filing confirms who holds a directorial or managerial mandate at the time of the most recent filing. It does not confirm:
- Whether that mandate is active at the date of the query
- Whether the director exercises actual control or is a nominee
- Whether there are side agreements (shareholders agreements, voting agreements, pledges) that modify the formal control picture
A director of record in Luxembourg is frequently a professional services provider. The mandate is real; the control may rest elsewhere. The sources establish the mandate. They do not establish the control behind it.
Financial statements: what is filed and what it shows
Luxembourg companies above certain size thresholds are required to file annual accounts with the RCS. These accounts are available through the LBR portal. For companies below the threshold, filing may be limited or exempt.
Filed accounts show the balance sheet and profit-and-loss position as of the filing date. They do not show:
- Off-balance-sheet commitments
- Intercompany loan structures
- Pledges over shares or assets not reflected in the balance sheet
For a holding company — the most common Luxembourg counterparty structure — the accounts may show little more than the book value of participations and intercompany receivables. The economic substance of the underlying assets is not visible from the Luxembourg filing alone.
The limit of what the sources allow
The RCS/LBR establishes legal existence, the director of record, and the filing history. It does not establish who controls the company in fact.
The RBE, where accessible, establishes the declared beneficial owner. It does not verify the declaration against the underlying chain.
The shareholder register of an SA is not publicly accessible. For an Sàrl, the filed version reflects the position at the date of the last filed amendment — not necessarily the current position.
The ceiling of what the sources allow is stated before payment. For a Luxembourg holding company with a multi-layer ownership chain, the sources establish the visible layers and name the layer where the chain stops. They do not reach through an intermediate holding vehicle in a jurisdiction that does not publish its shareholder register.
Where the sources disagree — for example, where the RCS director list and the filed accounts show different signatories, or where the RBE declaration does not match the shareholder structure visible in filed documents — that discrepancy is itself a result. It is reported as such, not resolved by inference.
Where the sources disagree
Discrepancies between sources are reported as findings, not reconciled by assumption. Common patterns in Luxembourg counterparty files:
Each discrepancy is flagged. None is resolved without a source that closes the gap.

FAQ
What does the RCS/LBR actually show for a Luxembourg Sàrl before a shareholders agreement?
The register shows the company's legal name, registered address, directors, managers, and filed documents including articles of association and, where filed, shareholder lists. Most documents are available as PDFs at no charge. The register does not show the current beneficial owner or any side agreements that modify the formal governance structure.
Can a foreign buyer access the Luxembourg UBO register?
Following the CJEU ruling of November 2022, public access to the RBE is restricted. A foreign buyer may apply under the legitimate interest ground. The application is subject to assessment. The outcome is not guaranteed, and the timeline depends on the Luxembourg authority's processing.
What is the difference between the director of record and the person who controls the company?
The director of record is the person whose mandate is filed with the RCS. In Luxembourg, professional directors are common in holding structures. The mandate is a legal fact. Whether that person exercises actual control — or whether control rests with a shareholder, a creditor, or a party to a side agreement — is a separate question that the register does not answer.
Why does the report name the layer where the chain stops?
Because an incomplete chain is itself a result. A report that presents a partial ownership chain without identifying where it ends and why creates a false impression of completeness. The ceiling of what the sources allow is stated before payment.
Does a clean RCS entry mean the counterparty is low-risk?
A clean RCS entry means the company is registered and its filings are in order as of the last filing date. It does not mean the ownership structure is transparent, that there are no pledges over shares, or that the director of record exercises actual control.
