A shareholders agreement is signed between parties who expect to exercise rights inside the same company. Before that signature, the question is not only who the counterparty is on paper — it is who controls the entity, what constraints already bind the shares, and whether the structure on the register matches the structure in the room.
Luxembourg is a jurisdiction where the register is detailed and largely accessible. The ceiling of what the sources allow is stated before payment, not after.
The Registre de Commerce et des Sociétés (RCS) is the central corporate register for Luxembourg. It is administered by Luxembourg Business Registers (LBR). The register covers SARLs, SAs, SCAs, and other commercial entities incorporated under Luxembourg law.
Filed documents include the articles of association, amendments to those articles, appointments and resignations of managers and directors, changes to share capital, and — where applicable — annual accounts. Most of these documents are retrievable as PDF at no charge through the LBR portal.
The register records the registered managers and directors by name. For a SARL, the list of shareholders is filed with the articles and with subsequent amendments. For an SA, bearer shares were abolished; registered shareholders are recorded in the share register held by the company, not in the public RCS.
This distinction matters for counterparty analysis. For a SARL, the register provides a starting point for ownership. For an SA, the public register does not substitute for the company's own share register — which is not a public document.

The RCS records legal ownership and formal appointments. It does not record:
A counterparty who appears as a 25% shareholder in the register may hold that stake subject to a drag-along clause, a pledge in favour of a lender, or a side agreement that effectively transfers economic interest to a third party. None of these appear in the RCS.
Control, in the operational sense, is the capacity to direct decisions. The register records formal appointments and stated capital. The gap between the two is the subject of the analysis.
Luxembourg maintains a Registre des bénéficiaires effectifs (RBE) under the 2019 law implementing the Fourth and Fifth Anti-Money Laundering Directives. The RBE records the natural persons who ultimately own or control a Luxembourg entity above the statutory threshold.
Following the Court of Justice of the EU judgment in joined cases C-37/20 and C-601/20 (WM and Sovim, November 2022), public access to UBO registers across EU member states was restricted. Luxembourg suspended general public access to the RBE for persons without a demonstrated legitimate interest.
Access to the RBE is now conditional. A party seeking access must establish a legitimate interest. The conditions for that access, and the process for asserting it, are defined by Luxembourg law and administered by the RBE authority.
For counterparty analysis, this means: the beneficial ownership layer is not freely readable. Establishing who controls the entity at the natural-person level requires a formal access procedure. The outcome of that procedure is not guaranteed.
The analysis identifies the chain of ownership to the level the sources allow, names the point at which the chain ends, and states why.
Luxembourg companies above certain size thresholds are required to file annual accounts with the RCS. Filed accounts are accessible through the LBR portal. The availability of accounts depends on the legal form and size of the entity.
For a SARL or SA above the small-company threshold, filed accounts include the balance sheet, profit and loss statement, and notes. For micro-entities and certain holding structures, reduced filing obligations apply.
Filed accounts show the financial position as at the filing date. They do not show:
The gap between filed accounts and actual financial position is a standard feature of any register-based analysis. The analysis states what the filed documents show and where the filed record ends.

Luxembourg insolvency proceedings — faillite, concordat, sursis de paiement — are published in the Recueil Électronique des Sociétés et Associations (RESA) and recorded in the RCS. A search of the RCS returns open insolvency proceedings linked to the entity.
A negative result in the insolvency record does not guarantee the absence of a filed petition. Proceedings filed but not yet published, or proceedings in a foreign jurisdiction not yet recognised in Luxembourg, will not appear. The analysis states the scope of the search and its date.
Court judgments against the entity are not systematically consolidated in a single public register. Enforcement records require targeted searches across the relevant court databases. The analysis covers the sources that are accessible and names those that are not.
The RCS is a well-maintained register with broad document availability. Within that, the following limits apply:
The beneficial ownership register is not publicly accessible without a demonstrated legitimate interest. The natural person in ultimate control cannot be established from the RCS alone.
For SAs, the share register is a company document, not a public filing. The identity of shareholders is not verifiable from the RCS for this legal form.
Shareholders' agreements, pledges, nominee arrangements, and voting restrictions are private documents. They do not appear in any public register. Their existence can be inferred from indirect signals — cross-references in filed documents, pledge registrations, or inconsistencies between stated capital and economic behaviour — but not confirmed from public sources alone.
The analysis states, at each point, which source the finding comes from, what that source covers, and where it stops.
Filed documents in the RCS are submitted by the company or its representatives. The register records what was filed, not what is accurate. Discrepancies arise when:
Where the sources disagree, the analysis records the disagreement. A discrepancy between the register and the filed accounts is itself a finding.
What does the Luxembourg RCS show about shareholders? For a SARL, the articles of association and filed amendments record the shareholders by name and share. For an SA, shareholders are recorded in the company's own share register, which is not a public document. The RCS does not substitute for that register.
Can beneficial ownership be established from public sources? Not by default. The RBE holds beneficial ownership data, but public access is restricted following the CJEU ruling of November 2022. Access requires a demonstrated legitimate interest. The analysis identifies the chain of ownership to the level the sources allow and states where it ends.
What does a negative insolvency result mean? It means no open insolvency proceeding appears in the RCS or RESA as at the date of the search. It does not confirm the absence of a filed petition not yet published, or of proceedings in a foreign jurisdiction not yet recognised in Luxembourg.
Are shareholders' agreements visible in the register? No. Shareholders' agreements are private documents. They do not appear in any public register. The analysis identifies indirect signals — cross-references, pledge registrations, structural inconsistencies — but cannot confirm the content of private agreements.
What is the difference between the Signal and Standard tiers? Signal establishes the corporate identity, formal appointments, and open insolvency position. Standard adds the financial statement layer and a cross-reference analysis between the register and the filed accounts. Extended adds the beneficial ownership access procedure and cross-border chain analysis.
