A shareholders agreement assigns rights and obligations to named parties. Before signing, the question is not whether those parties exist — it is who controls the entity they represent, and what the official record shows about that control. Luxembourg maintains several distinct layers of official disclosure. Each layer answers a different question, carries its own access condition, and stops at a defined point.
Control in a Luxembourg company is distributed across three planes: registered directorship, declared beneficial ownership, and actual economic interest. Official sources address the first two directly. The third is inferred from the first two combined with filed documents. This page maps what each source discloses, what it costs to extract, how long extraction takes, and where the chain ends.

TurnaroundRCS extracts: same-day to two business days. RBE access: variable; depends on legitimate-interest procedure in force at time of request.The RCS is the foundational corporate register for Luxembourg entities. It records the legal existence of the company, its registered address, its legal form, and the identity of persons authorised to bind it — directors, managers (gérants), and statutory auditors where applicable.
For a société à responsabilité limitée (Sàrl), the RCS lists gérants by name and shows whether their mandate is current or expired. For a société anonyme (SA), it lists board members and the managing director where one is appointed. Filed documents — including articles of association and amendments — are accessible through the LBR portal.
The RCS does not show who appointed the directors. It does not show the terms of any shareholders agreement governing removal or replacement. It does not show whether a director acts under instruction from a third party. Those questions are answered by the shareholders agreement itself, not by the register.

The RBE was established under Luxembourg law of 13 January 2019, transposing the 4th and 5th AML Directives. It requires Luxembourg entities to declare their beneficial owners — defined as natural persons holding, directly or indirectly, more than 25% of shares or voting rights, or exercising control by other means.
The RBE record shows the beneficial owner's name, nationality, country of residence, date of birth, and the nature and extent of the beneficial interest held. It does not show the full chain of intermediate holding entities. It does not show the contractual basis of control. It does not show whether the declared percentage reflects economic interest or voting power separately.
Access conditions after CJEU C-37/20. The Court of Justice ruling of 22 November 2022 found that unrestricted public access to UBO registers is incompatible with fundamental rights under the Charter. Luxembourg suspended general public access to the RBE following that ruling. Access for third parties now requires demonstration of a legitimate interest. The procedure, its requirements, and its turnaround are defined by Luxembourg administrative practice and are subject to change. No exact fee or timeline can be stated here without verification at the time of the specific request.

The LBR portal provides access to documents filed with the RCS, including the coordinated articles of association (statuts coordonnés). For Sàrl entities, the articles typically identify the gérants and the initial shareholders. Amendments — including changes to share capital and transfers of parts sociales — must be filed and are accessible.
For SA entities, the articles define the governance structure but do not necessarily identify individual shareholders. Bearer shares were abolished in Luxembourg as of 2014; all shares are now registered. However, the shareholder register of an SA is maintained by the company itself and is not filed with the RCS. It is not accessible through the public register.
This distinction matters before signing a shareholders agreement. For a Sàrl, the filed documents provide a partial picture of the ownership structure. For an SA, the public record shows governance structure only; ownership must be established through other means.

The RCS records insolvency proceedings, judicial dissolution, and suspension of payments (sursis de paiement) for Luxembourg entities. A search of the RCS by company identifier returns any such entries if they have been filed.
The Luxembourg court portal (Justice.lu) provides access to published judicial decisions. Commercial court judgments involving Luxembourg entities are published where required by law. Not all proceedings result in published decisions; interim measures and certain enforcement steps may not appear in the public record.
A negative result in the insolvency layer of the RCS does not confirm the absence of a filed application that has not yet been processed. Turnaround between filing and registration varies.

Three factors determine how long extraction takes for a Luxembourg corporate record.
Source layer. RCS extracts are available through the LBR portal on a per-document basis and are typically processed within one to two business days. The RBE legitimate-interest procedure adds a variable step that depends on the administrative workload of the register at the time of the request.
Language. Documents filed with the RCS are in French, German, or Luxembourgish. Articles of association and shareholder lists are most commonly in French. Translation and legal review add time proportional to document volume.
Chain depth. Where the declared beneficial owner is a legal entity rather than a natural person, the chain must be traced upward through the intermediate entity's own register. Each additional jurisdiction adds its own access condition and turnaround. Luxembourg holding structures frequently involve intermediate entities in other EU jurisdictions or in third countries. The total timeline is the sum of each step, not the longest single step.
The RCS and RBE together establish who is named as director and who is declared as beneficial owner. They do not establish whether that declaration is accurate. They do not show side agreements, nominee arrangements, or undisclosed economic interests. They do not show the terms on which a director was appointed or can be removed.
The RBE shows a percentage and a nature of interest. It does not show the contractual structure that produces that percentage. A 26% declared interest and a 74% declared interest may be subject to a shareholders agreement that reverses effective control entirely. The register does not capture that agreement.
For a Sàrl, filed documents provide a partial ownership picture. For an SA, the public record stops at governance structure. The shareholder register of an SA is a private document; it is not accessible through the public register without the cooperation of the company or a court order.
The ceiling of what the sources allow is stated before payment. Where a source stops, the report states that it stops and identifies the specific point of interruption.
Discrepancies between the RCS and the RBE are a result in themselves. A director named in the RCS who does not appear in the RBE as beneficial owner, combined with a declared beneficial owner who holds no directorship, indicates a separation of formal control from economic interest. That separation is the structure, not an anomaly.
Discrepancies between the RBE declaration and the filed articles of association — for example, a declared percentage that does not correspond to any share class described in the articles — require explanation. The report identifies the discrepancy and names the source of each conflicting figure.
Where the intermediate holding entity is registered in a jurisdiction that does not maintain a public UBO register, the chain cannot be traced beyond the Luxembourg declaration. The report states the point at which the chain terminates and the reason.

What is the difference between a director and a beneficial owner in Luxembourg? A director (administrateur or gérant) is the person authorised to act on behalf of the company. A beneficial owner is the natural person who ultimately owns or controls it. The two roles may be held by the same person or by entirely different persons. The RCS records the director; the RBE records the beneficial owner. Both registers must be consulted to establish the full control picture.
Can the RBE be accessed by a third party before signing a shareholders agreement? Following CJEU C-37/20, Luxembourg suspended general public access to the RBE. Third-party access requires demonstration of a legitimate interest. The specific requirements and turnaround depend on the administrative procedure in force at the time of the request. This is confirmed at the outset of each engagement, before work begins.
What happens if the beneficial owner is declared as a legal entity rather than a natural person? The RBE requires declaration of the ultimate natural person. A legal entity in the beneficial owner field indicates either an incomplete declaration or a structure where the natural person sits above the Luxembourg entity in a foreign jurisdiction. In either case, the chain must be traced further. The Standard and Extended tiers cover this tracing within defined scope limits.
How long does a Luxembourg director and UBO report take? The RCS layer is typically completed within two to four business days. The RBE layer adds time depending on the legitimate-interest procedure. A Signal report is typically delivered within three to five business days. Standard and Extended reports depend on the complexity of the holding structure and the number of jurisdictions involved. A timeline estimate is provided at the outset of each engagement.
Does a negative insolvency result confirm the company is solvent? No. A negative result in the RCS insolvency layer confirms that no insolvency proceeding, judicial dissolution, or suspension of payments has been registered against the company at the time of the search. It does not confirm solvency. It does not capture proceedings filed but not yet registered.
