Before a shareholders agreement is signed, the governance layer of a Luxembourg company must be read from official sources — not inferred from representations. This page describes what those sources contain, how to reach them as a foreign requester, and where the chain of verifiable facts ends.
The angle here is governance: who controls the company, on what legal basis, and what a shareholder can enforce. That question is answered by documents, not by declarations.

The RCS is the primary official source for Luxembourg corporate records. It holds the articles of association (statuts), the instrument of incorporation, and all subsequent amendments filed by notarial deed or private instrument.
For a governance review before signing, the RCS provides the following:
The articles of association state the share capital structure, the classes of shares, voting rights attached to each class, quorum and majority thresholds for general meetings, and the scope of authority delegated to the board or gérant. These are the terms a shareholder can enforce.
Director and manager appointments are filed as separate instruments. The RCS shows the current mandate holders, the date of appointment, and — where filed — the scope of their signing authority. Revocations and resignations are recorded as they occur.
For a SARL, the list of associés (shareholders) with their respective parts sociales is filed with the RCS and updated on each transfer. This is the source for verifying the shareholding structure at the time of review.
For an SA, the register of registered shares is maintained by the company itself, not by the RCS. Bearer shares were abolished under the law of 28 July 2014. Dematerialised registered shares are held through a central securities depository or a registrar appointed by the company. The RCS does not hold the shareholder register for an SA.

The beneficial ownership layer
Luxembourg established the RBE under the law of 13 January 2019, implementing the Fourth Anti-Money Laundering Directive. The register records the identity of ultimate beneficial owners (UBOs) holding more than 25 percent of shares or voting rights, or exercising control by other means.
Following the CJEU judgment in Joined Cases C-37/20 and C-601/20 (WM and Sovim, November 2022), access to the RBE for members of the general public was suspended. The Luxembourg Court of Appeal confirmed this suspension in subsequent national proceedings.
Access to the RBE is now conditional on demonstrating a legitimate interest. The categories of persons with a recognised legitimate interest include competent authorities, obliged entities conducting customer due diligence, and persons who can establish a specific, documented connection to the risk of money laundering or terrorist financing in relation to the entity concerned.
A foreign requester who cannot satisfy the legitimate interest condition will not obtain RBE data through the standard access route. The mechanism for establishing legitimate interest, and the authority that evaluates it, are set out in the amended law of 13 January 2019 and the implementing regulations.
The RBE data, where accessible, shows the UBO's name, nationality, date of birth, country of residence, and the nature and extent of the beneficial interest held. It does not show the contractual arrangements — such as a shareholders agreement or a trust deed — through which control is exercised.

Financial statements and what they show
Luxembourg companies above the statutory size thresholds are required to file annual accounts with the RCS. The filing obligation applies to SA, SARL, SCA, and SE entities. Micro-entities and certain holding structures benefit from reduced disclosure requirements.
Filed accounts are accessible through the RCS portal. They show the balance sheet, the profit and loss account, and — for larger entities — notes to the accounts including related-party transactions and off-balance-sheet commitments.
For a pre-deal governance review, filed accounts serve a specific function: they allow verification of whether the company's financial position is consistent with the representations made in the transaction. Discrepancies between filed accounts and management accounts provided by the seller are themselves a finding.
Accounts are filed in Luxembourg Francs, EUR, or the functional currency of the entity. The filing deadline is seven months after the close of the financial year. Late filing is common; the absence of a filed account for a recent year does not confirm that accounts were not prepared — it confirms only that they were not filed on time.

Governance documents not in the public record
A shareholders agreement in Luxembourg is a private contract between the parties. It is not filed with the RCS, not registered with any public authority, and not accessible through any official source.
The existence of a shareholders agreement may be inferred from references in the articles of association — for example, a clause stating that transfers of shares are subject to conditions set out in a separate agreement. The articles may also incorporate tag-along, drag-along, or pre-emption provisions directly, in which case those terms are visible in the RCS filing.
Where governance arrangements are structured through a fiducie (Luxembourg trust equivalent under the law of 27 July 2003), the fiduciary relationship is not publicly registered. The beneficiary of the fiducie does not appear in the RCS or the RBE as a shareholder.
Pledges over shares (nantissement de parts) must be notified to the company and, for SARLs, are recorded in the shareholder register. A pledge does not appear in the RCS unless it is filed as a separate instrument. The absence of a filed pledge does not confirm that no pledge exists.

Step-by-step: the access path for a foreign requester
The sequence below describes the standard path for a foreign requester conducting a governance review before signing.
Step 1 — RCS company search. The RCS portal allows free text and identifier-based search. The company's RCS number (numéro d'immatriculation) is the reliable search key. The portal returns the current registration certificate, the filed articles, and the list of mandataires. Documents are available in PDF format.
Step 2 — Identify the entity type. The governance structure differs materially between a SARL and an SA. For a SARL, the shareholder list is in the RCS. For an SA, it is not. This determination shapes the rest of the review.
Step 3 — Retrieve filed amendments. Every amendment to the articles, every change of director, and every capital modification is filed as a separate instrument. A complete governance picture requires reading the original articles and all subsequent amendments in sequence, not only the most recent consolidated version.
Step 4 — RBE access assessment. Before submitting an RBE request, the requester must assess whether a legitimate interest can be demonstrated. The assessment is not formal at this stage — it is a factual question about whether the requester's connection to the entity meets the statutory threshold. If it does not, the RBE route is unavailable and the beneficial ownership layer must be approached through other official sources.
Step 5 — Financial statement retrieval. Filed accounts are retrieved from the RCS portal. The review covers the most recent filed year and, where available, the two preceding years. Gaps in filing history are noted as findings, not resolved by assumption.
Step 6 — Cross-reference. The governance picture assembled from the RCS, the RBE (where accessible), and the filed accounts is cross-referenced against the representations in the transaction documents. Discrepancies are documented.

The limit of what the sources allow
The RCS shows what has been filed. It does not show what has been agreed privately. A shareholders agreement that restricts transfer, grants veto rights, or creates a deadlock mechanism is invisible in the public record unless its terms are reproduced in the articles of association.
The RBE shows the declared beneficial owner. It does not show the contractual basis of that ownership, the conditions under which it can be transferred, or whether a fiduciary arrangement sits above the declared UBO. Following the CJEU judgment, the RBE is not accessible to a foreign requester who cannot establish legitimate interest through the statutory mechanism.
The shareholder register of an SA is held by the company or its registrar. It is not a public document. A foreign requester cannot obtain it through the RCS. The only route is a contractual right of inspection — which presupposes that the transaction has already progressed to a stage where such rights have been granted.
Filed accounts reflect what was reported, not what occurred. A Luxembourg holding company with no operational activity may file accounts that show only the holding structure, with no disclosure of the terms on which the underlying assets are held.
The ceiling of what the sources allow is stated before payment. Where a source is inaccessible to a foreign requester, that fact is identified at the outset — not discovered after the review has begun.
Where the sources disagree
The most common discrepancy in a Luxembourg governance review is between the declared UBO in the RBE and the economic beneficiary implied by the shareholding structure in the RCS.
A Luxembourg SARL may show a corporate shareholder in the RCS — a holding company in another jurisdiction — while the RBE declares an individual UBO. The connection between the two is asserted in the RBE filing but is not independently verifiable from Luxembourg public sources alone. Verification requires cross-referencing the foreign holding company's own register.
A second common discrepancy arises between the scope of authority stated in the articles of association and the scope of authority stated in a board resolution or a power of attorney filed separately. Where these conflict, the articles govern — but the conflict itself is a governance finding.
A third discrepancy arises where the filed accounts show a capital structure inconsistent with the shareholder list in the RCS. This may reflect a capital increase that was filed with the RCS but not yet reflected in the accounts, or vice versa. The sequence of filings and the dates of each instrument determine which version is current.

FAQ
Does a Luxembourg shareholders agreement appear in any public register? No. A shareholders agreement is a private contract. It is not filed with the RCS, not registered with any public authority, and not accessible through any official source. Its existence may be inferred from references in the articles of association, but its terms are not publicly available.
Can a foreign requester access the RBE without establishing legitimate interest? No. Following the CJEU judgment of November 2022 and the subsequent suspension of general public access, the RBE is accessible only to persons who can demonstrate a legitimate interest within the meaning of the amended law of 13 January 2019. A requester who cannot satisfy this condition will not obtain RBE data through the standard route.
Where is the shareholder register of a Luxembourg SA held? The shareholder register of an SA is held by the company or by a registrar appointed by the company. It is not filed with the RCS and is not a public document. Access requires a contractual right of inspection.
What does the RCS show for a SARL versus an SA? For a SARL, the list of associés with their parts sociales is filed with the RCS and updated on each transfer. For an SA, the shareholder register is not filed with the RCS. This distinction is material for a pre-deal governance review and is identified at Step 2 of the access path.
What is the significance of a filing gap in the annual accounts? A gap in the filing history — where accounts for one or more years are absent from the RCS — is recorded as a finding. It confirms that accounts were not filed on time; it does not confirm that accounts were not prepared. The gap itself is relevant to the governance picture.
What happens if the RBE is inaccessible? Where the RBE is inaccessible to a foreign requester, the beneficial ownership layer must be approached through other official sources — including the registers of any intermediate holding companies in other jurisdictions. The limit of what Luxembourg sources alone can establish is identified at the outset of the review.
