Reserved matters and veto design in Luxembourg

Reserved matters and veto design in Luxembourg start from a narrower base than most founders assume: the law already reserves a fixed list of decisions to the general meeting, and anything a shareholder wants to veto beyond that list only has force if it is built into the articles of association or into a shareholders' agreement drafted to match them. A board or a manager acting on this in Luxembourg is working inside a mandatory core, not drafting on a blank page.

A private equity investor holding a minority stake in a Luxembourg société à responsabilité limitée wants a veto over new borrowing, a change of business and the appointment of the next manager. The founders have agreed the principle at term sheet stage. What nobody has confirmed yet is whether that veto will sit in the articles, where it binds the company and any incoming manager, or only in a side letter, where it binds the signatories and nobody else.

This page sets out what a group doing business in Luxembourg already has by statute before any drafting starts, where an added veto becomes public and enforceable against third parties once it is entrenched, and where the firm's advisory role in that process stops.

What changes in Luxembourg

The generic version of this work asks what a board and its shareholders want to reserve for themselves and how to draft it so a court will enforce the split. In Luxembourg that question sits on top of a statutory floor that exists before anyone drafts anything at all. Amending the articles of association of a Luxembourg company requires a resolution of the general meeting passed by shareholders representing at least two thirds of the votes cast, at a meeting where at least half the share capital is represented. 01 That threshold is not a drafting choice available to the parties. It is the mechanism through which any additional reserved matter has to pass if it is meant to bind the company itself, rather than only the people who signed a side agreement.

This matters for veto design specifically, and it matters differently depending on the corporate form chosen. A société anonyme has a board of directors, and a veto over a board decision has to be written into the articles or into the powers given to individual directors on appointment. A société à responsabilité limitée usually has a single manager or a board of managers instead, and the same veto question is asked of that manager's authority rather than of a board. A shareholder who wants a veto over, say, a change of manager can get it in three different ways in Luxembourg, and each way survives a different set of events. Written into the articles, it binds the company, is filed on the public record, and travels with the shares. Written only into a shareholders' agreement, it binds the parties to that agreement personally and lapses if one of them exits without a fresh signature. Written as a class of shares carrying attached rights, it sits between the two, and which of the three a client actually has is the first thing to confirm, not the last.

The comparable page for the wider practice sets out the drafting logic that applies before any single jurisdiction is chosen. Reserved matters and veto design is the place to start if the structure has not yet been fixed on one country.

The local requirement or test that drives the work

The test a Luxembourg board or manager has to apply is not "does the shareholder have a veto" but "is the matter one the law already reserves, and if not, has it been entrenched in the one document that binds the company." Luxembourg company legislation reserves a defined set of matters to the general meeting by mandatory qualified majority: amendment of the articles, changes to the share capital, merger, division and dissolution sit inside that set regardless of what any side letter says. The two-thirds and half-capital thresholds apply to each of them. 01

Once the reserved-matter list is agreed to run wider than that statutory floor, for example to cover new borrowing above a set figure or the appointment of the next manager, the drafting question becomes where to put it. A veto agreed at term sheet stage does not disappear the moment it becomes commercially useful, but it also does not migrate itself into the articles. It stops binding the company at exactly the point a transaction is concluded on the strength of authority that is, on the public record, unqualified. Once that facility is drawn and the lender has relied on the manager's authority as filed, the shareholder cannot unwind the borrowing by producing a private document the lender never saw; the remedy that survives runs against the manager personally, not against the loan.

A second, quieter difference from the generic version of this work: Luxembourg draws a real distinction between a manager's internal authority, meaning what the shareholders have agreed among themselves, and the manager's power to bind the company towards a third party acting in good faith. Reserved matters drafted only as an internal limit do not, by themselves, put a lender or a counterparty on notice of anything. That notice comes from what is actually filed, which is the subject of the next section.

The filing, register or forum consequence

An amendment to a Luxembourg company's articles of association must be filed with the Luxembourg Trade and Companies Register and published through the electronic company register, RESA. 02 That statutory filing is the moment a reserved matter or a veto stops being a private arrangement between shareholders and becomes something a lender, a counterparty or a future buyer can check before dealing with the company. It also fixes the record: once the amendment is filed and published, it cannot be withdrawn by a later private agreement between the shareholders; the only route back is a further amendment, adopted with the same majority, filed and published in the same way.

That has a direct consequence for sequencing, and it is the point most groups get wrong. A group that files the amended articles before the shareholders' agreement is finished is publishing a veto structure the final agreement may not match, and the mismatch is then visible to anyone who checks the register. A group that finishes the agreement first and files the articles second is exposed for the gap in between: any borrowing, any appointment, any transaction concluded before filing relies on whatever authority the manager had on the public record at the time, not on what the shareholders privately agreed the week before. The resolution adopting the amendment belongs in the minute book, but the minute book itself is not the public record; the filed and published articles are what a third party is entitled to rely on.

A shareholders' agreement is not itself filed with the Luxembourg Trade and Companies Register, and its terms have no effect against the company or against a third party unless they are mirrored in the articles of association. 03 That single fact decides where most of the drafting time on this work actually goes: not on inventing veto language, but on deciding which of it needs to be public to bind the company, and which can stay private because the parties are content for it to bind only each other.

Enforcement of a breached veto that was never migrated into the articles proceeds as a contract claim between the shareholders, in the forum the shareholders' agreement names, not as a challenge to a board or management decision the company itself is bound to reverse. That distinction affects which remedy is actually available and how quickly it can be obtained, and it is worth settling before the veto is drafted, not after it has been breached.

What this service does not include in Luxembourg

The firm maps the reserved-matter and veto structure a Luxembourg company needs, drafts or reviews the articles and the shareholders' agreement that carry it, and assesses where each choice leaves a manager or director personally exposed. It does not act as, supply, source or arrange a manager, a director, a company secretary, a nominee shareholder or a trustee for the company, and it does not carry out any activity for which a trust or corporate service provider licence is required in Luxembourg or elsewhere. That boundary is set by licensing, not by preference: acting in those capacities, or arranging for someone else to, is regulated activity in a majority of the jurisdictions this practice covers, Luxembourg among them, and a firm that only advises has no authorisation to cross it.

What the client receives instead is concrete rather than administrative: the reserved-matter list mapped against the statutory floor described above, draft or reviewed language for the articles and the shareholders' agreement, a written assessment of what stays private and what becomes public on filing, and a review of the director appointment terms offered to the person who will have to operate under the veto once it is in place. A director appointment that is silent on the reserved-matter list is a common source of the exposure described above, and reviewing it before signature is usually cheaper than resolving a breach afterward.

Before any of that is finalised, it is worth having the following in hand:

• The current articles of association, in the version actually filed, not a working draft
• A list of the decisions the parties want reserved, ranked by how commercially urgent each one is
• The manager's or director's appointment terms and any existing signing authority already on the register
• Confirmation of who is entitled to vote at the two-thirds threshold if the shareholding is not evenly split

A group weighing this question against a comparable structure elsewhere can set the two side by side. Reserved matters and veto design in Malta covers the equivalent test in a jurisdiction with a different majority rule, and this comparison of contractual against constitutional veto protection sets the choice out directly, without reference to any single country. Where the veto interacts with an exit or deadlock mechanism already in the shareholders' agreement, drag and tag enforcement in Luxembourg covers what happens when the two mechanisms are triggered together. The sequencing question raised above, filing the articles before or after the shareholders' agreement is finished, is addressed in more detail in sequencing and timing for reserved matters and veto design.

A holding company that has never had to test any of this in practice is not necessarily well served by it. The point of settling the allocation now, while the parties are still on good terms, is that the same allocation has to hold once they are not.

Frequently asked questions

What happens if reserved matters and veto design in Luxembourg is not addressed?

The statutory floor still applies regardless, so amendments to the articles and the other matters the law reserves still need the qualified majority described above. What is missing is everything above that floor: a manager can borrow, appoint or contract without any check the shareholders thought they had, because a veto that exists only in conversation binds nobody.

How often should reserved matters and veto design in Luxembourg be reviewed?

Whenever the shareholding changes, whenever a new manager or director is appointed, and whenever the company takes on financing that was not contemplated when the articles were last filed. A veto drafted around one capital structure does not automatically survive a round that changes who holds the two-thirds.

Does reserved matters and veto design in Luxembourg change for a foreign-owned company?

The statutory majority and filing requirements apply the same way regardless of where the shareholders are based. What usually changes for a foreign-owned company is the manager: a parent based elsewhere is relying on someone local to observe a veto that person did not negotiate, which is why the director appointment terms are worth reviewing separately from the veto language itself.

What does reserved matters and veto design in Luxembourg require in practice?

A decision, for each reserved matter, whether it needs to sit in the articles to bind the company and third parties, or whether it can stay in the shareholders' agreement because the parties only need it to bind each other. Most of the drafting work is in making that allocation correctly, not in the wording of the veto itself.

Who inside the company is responsible for reserved matters and veto design in Luxembourg?

The manager or director is the person who acts on the articles as filed and is personally exposed if a transaction breaches a reserved matter that was properly entrenched. The shareholders are the ones who decide what gets entrenched. Neither can discharge the other's part of that division.

Elena Vogt, expert author at Halvorsen & Reith, focuses on constitutional documents and governance design across common-law and civil-law jurisdictions. She reasons from the constitution outward, testing how reserved-matter and veto language actually binds a board or a manager once it is filed rather than how it reads on the page.
