Luxembourg Company Lookup: Where the UBO Case Began

A Luxembourg company lookup runs through the Registre de Commerce et des Sociétés (RCS), kept under the authority of the Minister of Justice and managed by Luxembourg Business Registers (LBR) — a groupement d'intérêt économique whose members are the Luxembourg State, the Chambre de Commerce and the Chambre des Métiers. The RCS is at lbr.lu, and the RBE portal sits alongside it. This guide covers the four registers LBR operates, the institutional arrangement behind them, and the documented history of public access to the beneficial ownership register. If you need the Luxembourg population rather than one company at a time, the Luxembourg company directory covers the same registered entities with industry, size and contact breakdowns attached, and the Luxembourg business database is the same file described as a dataset.

Luxembourg company lookup: the short version

• One operator, four registers: LBR manages the RCS, the RBE (beneficial owners), REGINSOL (insolvency) and RESA (electronic publications), under the Minister of Justice.
• LBR is a groupement d'intérêt économique whose members are the State, the Chambre de Commerce and the Chambre des Métiers — not a ministry directorate and not an agency.
• The RBE opened to free public consultation on 1 September 2019. Following the CJEU judgment of 22 November 2022, access had to be temporarily suspended.
• This page does not state the current RBE access regime. Bill 7961 was tabled to reform the legal basis of both registers; check lbr.lu before relying on any access rule.

The register where the European UBO case begins

Several registers in this series operate under a judgment. This is the one it came from, and the sequence is worth setting out in dated facts rather than in summary.

The RBE — the Registre des bénéficiaires effectifs — is described by the State as "un répertoire officiel des entreprises qui permet l'identification des bénéficiaires effectifs par le public et les autorités nationales en charge de la lutte contre le blanchiment et le financement du terrorisme": an official directory of businesses allowing the identification of beneficial owners by the public and by the national authorities responsible for combating money laundering and terrorist financing. Entities registered in the RCS must declare their beneficial owners to the RBE.

1 September 2019. "Le RBE pourra être consulté gratuitement en ligne par le public à partir du 1er septembre 2019 sur le site du LBR, via le portail dédié au RBE." The RBE could be consulted free of charge online by the public from 1 September 2019, on LBR's site, via the portal dedicated to the RBE.

22 November 2022. The Chambre des Députés records what happened next: "Rappelons que suite à un Arrêt de la Cour de Justice de l'Union européenne du 22 novembre 2022, l'accès au registre des bénéficiaires effectifs avait temporairement dû être suspendu." Following a judgment of the Court of Justice of the European Union of 22 November 2022, access to the beneficial owners register had temporarily to be suspended.

Bill 7961 was tabled to reform the legal basis of both the RCS and the RBE.

Those are the four dated facts this page has, and they are the four it states.

What this page does not say

It does not describe the current access regime, and that omission is deliberate.

The source read here is a parliamentary account of a suspension and of a reform bill under discussion. It does not describe today's rules — not whether access has resumed, not whether a legitimate-interest route operates, not what a consulting party must record, and not what any subsequent change did. Those questions have real answers and this page does not have them.

A page that stated today's UBO rules from 2023 sources would be wrong within a paragraph, and wrong in the way that matters most: confidently, in an area where readers act on what they read. Check lbr.lu for the current access regime before relying on it.

The judgment matters beyond Luxembourg, and that is a fact of sequence rather than a judgement about the ruling. Beneficial ownership access changed across Europe after 22 November 2022, and several registers covered in this series carry consequences of it — the Sweden company lookup guide records that access to the Swedish register of beneficial owners is being adjusted from a stated date, and the Germany company lookup guide's own omissions list the Transparenzregister and the November 2022 ruling together as material still to be sourced. This page does not characterise the Court's reasoning — what it has is a one-sentence parliamentary summary, not the judgment.

One operator, four registers

The second thing worth knowing about Luxembourg is institutional, and it is genuinely unusual.

"LBR assure la gestion du registre de commerce et des sociétés (RCS), du Registre des bénéficiaires effectifs (RBE), du Registre de l'insolvabilité (REGINSOL) et du Recueil électronique des sociétés et association (RESA), sous la tutelle du ministre de la Justice."

LBR manages the Registre de Commerce et des Sociétés (RCS), the Registre des bénéficiaires effectifs (RBE), the Registre de l'insolvabilité (REGINSOL) and the Recueil électronique des sociétés et associations (RESA), under the authority of the Minister of Justice.

Four registers, one operator, and the practical consequence is a routing rule: a reader looking for insolvency is looking at REGINSOL, and a reader looking for statutory publications is looking at RESA — not at the RCS. They share an operator, not a scope.

The operator is a groupement d'intérêt économique

"Le RCS est placé sous l'autorité du Ministre de la Justice. La gestion du RCS est confiée par le Ministre de la Justice au groupement d'intérêt économique Luxembourg Business Registers (LBR) regroupant l'Etat luxembourgeois, la Chambre de Commerce et la Chambre des Métiers."

The RCS is placed under the authority of the Minister of Justice. Management of the RCS is entrusted by the Minister to the economic interest grouping Luxembourg Business Registers, bringing together the Luxembourg State, the Chambre de Commerce and the Chambre des Métiers. The State's own guichet confirms the form and the supervision: LBR is a GIE with those three members, and "Le LBR fonctionne sous la tutelle du ministre de la Justice."

Across this series the registers are kept by a range of bodies — courts in Germany, the Czech Republic, Poland and Croatia; agencies and ministries elsewhere; chambers of commerce in Italy, where the Italy company lookup guide covers a register held by the Camere di Commercio and operated by their IT consortium. Luxembourg's arrangement is a fourth shape: the State and two chambers as co-members of a single economic interest grouping, operating under a minister. None of these models is ranked here — they are different institutional answers, and the only practical consequence is knowing which body to address.

What a Luxembourg company register entry contains

A self-contained summary. Luxembourg's commercial register is the Registre de Commerce et des Sociétés (RCS), placed under the authority of the Minister of Justice, with management entrusted to the groupement d'intérêt économique Luxembourg Business Registers (LBR), whose members are the Luxembourg State, the Chambre de Commerce and the Chambre des Métiers, and which operates under the Minister of Justice's supervision. LBR manages four registers: the RCS, the Registre des bénéficiaires effectifs (RBE), the Registre de l'insolvabilité (REGINSOL) and the Recueil électronique des sociétés et associations (RESA). The RBE is described as an official directory of businesses allowing the identification of beneficial owners by the public and by the national authorities responsible for combating money laundering and terrorist financing, and entities registered in the RCS must declare their beneficial owners to it. Registration of beneficial ownership information, and of any changes to it, must be requested within one month of the entity learning, or having had reason to learn, of the event requiring the entry. The RBE could be consulted free of charge online by the public from 1 September 2019, on LBR's site via the portal dedicated to the RBE. Following a judgment of the Court of Justice of the European Union of 22 November 2022, access to the beneficial owners register had temporarily to be suspended, and bill 7961 was tabled to reform the legal basis of both the RCS and the RBE. Full RBE access requires being a professional within the meaning of article 2 of the amended law of 12 November 2004 on anti-money laundering and counter-terrorist financing, and holding a product issued by LuxTrust SA. This summary does not describe the current beneficial-ownership access regime, which was not established from the sources read on the date shown.

The one-month declaration window

One concrete freshness fact sits in the RBE rules and it is worth having.

Registration of beneficial ownership information, and of any changes to it, must be requested within one month of the entity learning, or having had reason to learn, of the event requiring the entry.

That is a stated maximum lag between a change in beneficial ownership and its declaration — a rare thing to have in writing. It applies to the RBE; nothing read here states a comparable window for RCS filings, and this page does not extend it to them.

Separately, and as a matter of the access conditions the sources do describe: full RBE access requires being a professional within the meaning of article 2 of the amended law of 12 November 2004 on anti-money laundering and counter-terrorist financing, and holding a product issued by LuxTrust SA. That is stated as a condition on full access; it is not, and is not offered as, a description of what public access currently looks like.

Where a Luxembourg lookup stops

This page stops in an unusual place, and naming it is more useful than working around it.

It does not state the current rules for consulting the RBE. It does not say the register is open, closed, or partially open today; it does not describe any legitimate-interest route; and it does not describe what a consulting party must record. The sources read establish a 2019 opening, a 2022 suspension and a reform bill, and nothing further. LUXEMBOURG_REPORT.md flags this first.

It also does not describe which entity types are exempt from RCS or RBE registration, or the threshold at which a person becomes a beneficial owner. The sources used both contexts and this page does not separate them on guesswork.

Where the question is a population rather than a company, a firmographic directory covers the same registered entities with classification, size and contact data attached and queryable as a set; the Europe company directory breaks the European file down by market.

Data quality pitfalls to avoid in Luxembourg

Assuming the RBE access rules you last read still hold. Access was suspended following the CJEU judgment of 22 November 2022 and a reform bill was tabled; the current regime is not described here and should be checked on lbr.lu.

Looking for insolvency in the RCS. REGINSOL is a separate register, managed by the same operator.

Looking for statutory publications in the RCS. RESA is the electronic recueil, also separate.

Treating LBR as a ministry directorate. It is a groupement d'intérêt économique whose members are the State and two chambers, operating under the Minister of Justice.

Applying the one-month window to RCS filings. It is stated for beneficial ownership declarations; nothing sourced here extends it.

Reading the professional-access condition as a description of public access. It is a condition on full RBE access, not a statement of what the public can currently see.

A repeatable Luxembourg company lookup workflow

1. Start at the RCS on lbr.lu for company identity and filings.
2. Go to REGINSOL for insolvency and to RESA for statutory publications.
3. Check the current RBE access regime on lbr.lu before planning any beneficial-ownership work.
4. Record the date you checked it, because this area has changed and may change again.
5. Expect beneficial-ownership changes to be declarable within one month of the entity learning of the event.
6. Address the right body: one operator, four registers, under the Minister of Justice.

Frequently asked questions

Who runs the Luxembourg company register?

Luxembourg Business Registers, a groupement d'intérêt économique whose members are the Luxembourg State, the Chambre de Commerce and the Chambre des Métiers, under the authority of the Minister of Justice.

Which registers does LBR manage?

Four: the RCS, the Registre des bénéficiaires effectifs, the Registre de l'insolvabilité (REGINSOL) and the Recueil électronique des sociétés et associations (RESA).

Was Luxembourg's beneficial ownership register public?

It could be consulted free of charge online by the public from 1 September 2019, via the portal dedicated to the RBE on LBR's site.

What happened to that access?

Following a judgment of the Court of Justice of the European Union of 22 November 2022, access to the beneficial owners register had temporarily to be suspended. Bill 7961 was tabled to reform the legal basis of both the RCS and the RBE.

What are the rules now?

This page does not say, because the sources read describe a suspension and a reform bill rather than today's regime. Check lbr.lu before relying on any access rule.

How quickly must beneficial ownership changes be declared?

Within one month of the entity learning, or having had reason to learn, of the event requiring the entry.

What does full RBE access require?

Being a professional within the meaning of article 2 of the amended law of 12 November 2004 on anti-money laundering and counter-terrorist financing, and holding a product issued by LuxTrust SA.

Source Register

Every French sentence quoted above is the publisher's own wording, read on the date shown, with an English gloss beside it rather than in place of it. No amount appears anywhere in this page's prose, and the beneficial-ownership threshold is absent for the same reason.

The most important thing about this page is what it refuses to state. The RBE section is written as history with dates — a 2019 opening, a 2022 suspension, a reform bill — because that is what the sources establish. It does not describe the current access regime in any form, and it says so twice, because a page that stated today's UBO rules from these sources would be confidently wrong in exactly the area where readers act on what they read.

The readings that are InfobelPRO's rather than the State's: that four registers under one operator is a routing rule rather than a convenience, so insolvency and statutory publications are separate destinations; and that LBR's form is a fourth institutional shape beside the courts, agencies and chambers that keep registers elsewhere in this series. Those are ours. The reference to the CJEU judgment is a statement of sequence — the judgment arose here, and beneficial ownership access changed across Europe afterwards — and this page neither characterises the Court's reasoning nor draws any causal claim about another country's rules.
