Board delegation and reserved matters in Luxembourg

Board delegation and reserved matters in Luxembourg turn on one distinction: what the board of directors can hand to a day-to-day manager, and what the law keeps with the board regardless of what the articles say. A société anonyme or société à responsabilité limitée that delegates management without mapping that boundary correctly risks a delegation that is either legally ineffective or wider than the board ever intended. This page sets out the local test, the filing consequence that follows from it, and where the advisory work stops.

A group with a Luxembourg holding company decides the board should stop signing every invoice and bank transfer itself, and instead delegate day-to-day management to one director or a manager. The board approves a resolution and moves on. Six months later, a lender or a co-investor asks to see the delegation on record, and the company discovers that what it approved internally was never filed, so the powers it relies on are not the powers the register shows.

This page settles what Luxembourg law reserves to the board, what the register requires once delegation happens, and what falls outside the advisory perimeter.

What changes in Luxembourg

Luxembourg company law does not treat delegation as a matter left entirely to the board's discretion. A board of directors may delegate the day-to-day management of the company to one or more delegates, but matters the law or the articles reserve to the board cannot be delegated away by resolution alone. 01 That is different from a jurisdiction where delegation is simply a question of internal authority mapping. In Luxembourg the line between what can be handed down and what stays with the board is a legal boundary, not a drafting choice.

For the position that applies across jurisdictions before the Luxembourg-specific test is layered on, see the cross-jurisdiction brief on board delegation and reserved matters. A foreign group doing business in Luxembourg for the first time typically inherits a delegation clause drafted for a different jurisdiction, and the clause reads fine until someone asks whether it actually covers the matters Luxembourg reserves to the board. Malta draws a broadly similar line but places it differently; see the Malta version of this test for the comparison.

The board delegation and reserved matters test in Luxembourg

The test is not whether the board wants to delegate a particular matter. It is whether that matter sits inside the category the law and the articles reserve to the board as a body, or outside it. A board resolution that purports to delegate a reserved matter does not change the category; it simply produces a delegation that a court or a counterparty is entitled to disregard on that point.

Once a delegation is exercised beyond what the board actually reserved to itself, the consequence is not simply that the act was irregular. A counterparty who relied on the register in good faith may still be entitled to treat the act as binding on the company, and the remedy the company would otherwise have against its own delegate for overreach becomes far harder to establish once the act has been completed and relied upon by someone outside the company.

Working out which matters fall on which side of that line means reading the company's own articles alongside the general board of directors framework, not assuming a template answer applies. On the sequencing question, when a delegation should take effect relative to when it is filed, see this analysis of sequencing and timing, because getting the order wrong is nearly as common as getting the scope wrong.

The filing and register consequence

The identity of a delegate holding day-to-day management powers, and the scope of the powers delegated, is a matter the Luxembourg Trade and Companies Register expects to be reflected in the company's filed particulars. 02 A delegation that is resolved internally but never carried through to the filing sits in an uncomfortable position. It exists as a corporate act, but a third party checking the register will not see it, and a third party checking the minute book is not something most counterparties do before signing.

Once the register has been relied on by a third party with no reason to look behind it, the company's ability to challenge a transaction on the basis that the delegate exceeded an unfiled restriction closes off. The register, not the internal minute, becomes the fact a court will treat as established.

The register of beneficial owners is a separate filing from the delegation of management powers, and appointing or changing a delegate does not by itself alter who is filed as a beneficial owner of the company. 03 Both entries are statutory filings, but they are not the same statutory filing, and groups sometimes assume the two move together. They do not, and treating them as one is a common source of an outdated beneficial ownership entry that surfaces later, usually during a financing or a sale.

Luxembourg does not require the company to file a separate list of the matters reserved to the board. The register records the delegation and its scope, not the boundary itself. That boundary is established by law and by the articles, and is not something a search of the register will produce. It is something the company has to work out from its own constitution. The same reserved-matters boundary resurfaces later if the group moves toward a buy-out; see buy-out valuation mechanics in Luxembourg for how it reappears in that context.

If the current delegation was drafted before the register filing was checked, the director appointment terms may say more, or less, than what the register and the beneficial ownership filing actually show. That gap is what a counterparty or a court looks at first if the delegation is ever tested.

What this service does not include in Luxembourg

The work on board delegation and reserved matters in Luxembourg maps the boundary above onto a specific company's constitution and board composition. It does not include acting as the delegate, the day-to-day manager or a director of the Luxembourg entity, and it does not include supplying, sourcing or arranging any person to hold that office. Luxembourg treats the provision of directors and similar office holders as a licensed activity, and advising a client on the boundary of its own delegation is a different thing from stepping inside that boundary as an office holder.

That distinction is not a preference. A firm without a trust and corporate service provider licence in Luxembourg cannot lawfully put forward a person to act as delegate or director for a client's structure, and no amount of drafting skill changes that. What the client receives instead is the requirement mapped against its own articles, the existing or proposed delegation tested against what the law reserves to the board, and a written assessment of where the current arrangement is exposed. For how a different jurisdiction frames the same director-requirement question, see this comparison of director requirements in the Netherlands and the ADGM.

• The categories of matter Luxembourg law reserves to the board as a body
• Whether the existing delegation resolution covers those categories correctly
• Whether the delegation has been carried through to the register
• What the beneficial ownership filing shows against the current management structure
• What a lender or counterparty would find on inspection

A board that delegates without confirming where Luxembourg draws the reserved-matters line is relying on a document nobody has tested against the register. That is a correctable position today and a much harder one once a transaction depends on it.

Frequently asked questions

Does board delegation and reserved matters in Luxembourg change for a foreign-owned company?

No. The test the law applies to what can be delegated and what stays with the board does not vary with who owns the company. What does vary is how carefully a foreign-owned board tends to check the point, because the template it started from was usually drafted for a different jurisdiction.

What does board delegation and reserved matters in Luxembourg require in practice?

The board has to resolve on the scope of the delegation, confirm that the scope excludes the matters reserved to it, and carry the delegate's identity and powers through to the register. Doing the first step without the third is the most common gap.

Who inside the company is responsible for board delegation and reserved matters in Luxembourg?

The board of directors as a body remains responsible for the matters the law reserves to it, even after delegation takes effect elsewhere in the company. Delegating day-to-day management does not delegate that residual responsibility.

What evidence should the board keep on board delegation and reserved matters in Luxembourg?

The board resolution setting the scope of the delegation, confirmation that the register filing reflects that scope, and a record of when the beneficial ownership filing was last checked against the current management structure. A minute book entry that was never filed is evidence of an intention, not of an effective delegation.

What happens if board delegation and reserved matters in Luxembourg is not addressed?

A delegate may act beyond what the board actually reserved, and a counterparty relying on the register in good faith can still treat that act as binding on the company. By the time this surfaces, usually during a financing or a dispute, the company's remedy against its own delegate is harder to establish than it would have been if the scope had been checked at the outset.
