A shareholders agreement in Luxembourg binds parties to a governance structure that official records may contradict. The question is not whether the company exists. The question is who controls it, on what terms, and whether those terms are visible before the signature page.
This page describes what Luxembourg's official sources disclose, how long each extraction step takes, and where the record stops. The ceiling of what the sources allow is stated before payment.

What the RCS does not showBeneficial ownership is held in a separate register. Shareholder lists for SARLs are filed but not always current. Financial statements are filed but filing compliance varies by entity type. Beneficial ownership registerThe Registre des Bénéficiaires Effectifs (RBE) is a separate register. Access conditions are subject to the CJEU ruling C-37/20 and subsequent Luxembourg implementation. Verified: 19.10.2026.What Luxembourg's corporate record contains
The RCS is the foundational layer. It holds the articles of incorporation, amendments, and the list of persons authorised to bind the company. For a société à responsabilité limitée (SARL), the shareholder list (liste des associés) is a filed document — but the filing obligation does not guarantee that the version on record reflects the current cap table.
Directors and managers appear in the RCS by name and function. Mandate dates are recorded. Resignation and appointment filings create a chronological sequence that can be reconstructed from the document history.
The RCS does not record the terms of a shareholders agreement. A shareholders agreement in Luxembourg is a private contract. It does not require filing and does not appear in any public register. Its existence, its content, and its enforceability against third parties are outside the scope of what the record discloses.

Governance layer: what drives control
Control in a Luxembourg SARL is distributed across three instruments: the articles of association, the shareholders agreement, and any management regulations (règlement interne). Only the articles are public. The other two are private.
The articles set the voting thresholds for ordinary and extraordinary decisions. They name the gérant or gérants. They may include transfer restrictions (clauses d'agrément) and pre-emption rights. These provisions are visible in the RCS filing.
What the articles do not capture: side arrangements on voting, drag-along and tag-along mechanics, information rights, and reserved matters. These live in the shareholders agreement. A buyer signing a new shareholders agreement without knowing the terms of any existing one is operating on an incomplete picture.
The RCS record establishes the public governance skeleton. The transaction report maps what that skeleton shows and where the private layer begins.

Beneficial ownership: the RBE layer
Luxembourg operates the Registre des Bénéficiaires Effectifs (RBE) under the Law of 13 January 2019. The RBE records the natural persons who ultimately own or control a Luxembourg entity above the statutory threshold.
Following the CJEU judgment in Joined Cases C-37/20 and C-601/20, Luxembourg restricted public access to the RBE. Access is no longer available to the general public without demonstration of a legitimate interest. The conditions under which a legitimate interest is accepted, and the procedure for establishing it, are defined by Luxembourg law and administered by the LBR.
For a transaction report, the relevant question is whether the RBE record can be accessed, what it shows when accessed, and whether the disclosed beneficial owner matches the ownership structure visible in the RCS. Discrepancies between the two registers are themselves a finding.

Financial statements: filing and availability
Luxembourg SARLs above certain size thresholds are required to file annual accounts with the RCS. Filed accounts are accessible through the LBR portal. The filing deadline is seven months after the financial year end.
Not all entities comply on time. The absence of a recent filing does not confirm that no accounts exist — it confirms that no accounts have been filed within the accessible period. The gap between the filing deadline and the actual filing date is itself a data point.
For a société anonyme (SA), the filing obligation is stricter and the accounts are more consistently available. For holding structures using a société en commandite spéciale (SCSp) or a société de participations financières (SOPARFI), the filing regime depends on the specific legal form and size criteria.
The transaction report identifies which accounts are on file, covers what period, and notes any gap relative to the statutory deadline.

Insolvency and enforcement record
Luxembourg insolvency proceedings — faillite, sursis de paiement, and reorganisation judiciaire — are recorded in the RCS and published in the Mémorial (now the Recueil électronique des sociétés et associations, RESA). A search of the RCS document history and the RESA publication record covers the formal insolvency layer.
The Banque Centrale du Luxembourg (BCL) maintains the Centrale des bilans, which holds financial data submitted by Luxembourg entities. Access to this data is restricted and subject to conditions.
A negative result in the insolvency record does not confirm the absence of a filed petition. It confirms the absence of a published record within the searched period. Proceedings filed but not yet published, or proceedings in foreign jurisdictions affecting Luxembourg entities, fall outside the scope of the Luxembourg record.

Timeline and what drives it
| Step | Source | Typical turnaround | What extends it |
|---|---|---|---|
| RCS entity extract and document history | LBR portal | 1–2 business days | Volume of filed amendments; older filings in paper format |
| Shareholder list (SARL) | LBR portal | 1–2 business days | Gaps in filing history require manual reconstruction |
| RBE beneficial ownership | LBR (legitimate interest procedure) | Variable | Demonstration of legitimate interest; LBR processing time |
| Filed financial statements | LBR portal | 1–2 business days | Missing filings require gap notation |
| RESA insolvency search | RESA portal | 1 business day | Historical searches pre-dating electronic publication |
| Director mandate history | RCS document sequence | 2–3 business days | Overlapping mandates; unsigned or late-filed resignations |
| Cross-border holding layer | Foreign registries (jurisdiction-dependent) | 3–10 business days | Registry access conditions in each upstream jurisdiction |
The cross-border holding layer is the primary variable. Luxembourg is frequently used as an intermediate holding jurisdiction. The entity at the RCS level may be wholly owned by a structure in another jurisdiction. Establishing control at the level of the natural person requires following the chain upstream, through each registry in sequence.
Where the sources disagree
The RCS shareholder list and the RBE beneficial ownership record are maintained independently. Discrepancies arise when a transfer of shares is not reflected in a timely RBE update, or when the threshold calculation differs between the two filings.
Filed financial statements may show a capital structure that does not match the current RCS shareholder list. This occurs when a capital increase or reduction has been registered but the accounts predate the transaction.
Where sources disagree, the report states the disagreement explicitly. It does not resolve it. Resolution requires either a direct request to the company or legal proceedings. Neither is within the scope of a records report.
The limit of what the sources allow
The RCS shows the public governance skeleton: legal form, registered persons, filed documents. It does not show the shareholders agreement, any side letters, or the terms on which control is actually exercised.
The RBE shows the declared beneficial owner above the statutory threshold. It does not show economic arrangements that fall below that threshold, nominee structures where the nominee is the declared owner, or arrangements that have not been updated following a change.
Filed financial statements show what was filed. They do not show management accounts, intercompany arrangements, or the financial position at the date of the transaction.
The insolvency record shows published proceedings in Luxembourg. It does not show foreign proceedings, informal restructuring, or creditor arrangements that have not entered a formal insolvency process.
The ceiling of what the sources allow is stated before payment. The report delivers what the sources contain. It names the point at which the record ends and the private layer begins.

FAQ
What does a transaction report cover that a standard due diligence checklist does not? A standard checklist identifies categories of information to request from the counterparty. A transaction report extracts what is independently verifiable from official sources, without relying on the counterparty's disclosure. The two are complementary. The report establishes the baseline against which disclosed documents are checked.
Can the shareholders agreement itself be obtained from the register? No. A Luxembourg shareholders agreement is a private contract. It is not filed with the RCS and does not appear in any public register. The report establishes what the articles of association contain and notes the absence of any filed governance document beyond the statutory minimum.
How is the RBE accessed after the CJEU ruling? Access requires demonstration of a legitimate interest to the LBR. The procedure, the accepted grounds, and the processing time are defined by Luxembourg law. The report covers the access attempt and records the outcome — whether access was granted, what was disclosed, or what was declined.
What happens if the Luxembourg entity is owned by a holding company in another jurisdiction? The RCS record shows the immediate shareholder. If that shareholder is a foreign entity, the chain continues into the foreign registry. The Signal and Standard tiers cover the Luxembourg layer only. The Extended tier traces the chain upstream through each intermediate jurisdiction.
How long does the full Extended report take? The Luxembourg layer is typically complete within five to seven business days. The cross-border layer depends on the number of intermediate jurisdictions and the access conditions in each. A realistic timeline for a multi-layer structure is two to four weeks from instruction.
What if a filing is missing or outdated? The report notes the gap explicitly: which document, which period, and what the statutory deadline was. A gap is a finding. It is not resolved by the report — resolution requires direct engagement with the company or its advisers.
