Drawing up a shareholders' agreement in Luxembourg
Published on 10 October 2026 · Updated on 10 October 2026
In short
A shareholders' agreement in Luxembourg is a private contract that governs relations between shareholders beyond the articles: governance, entry into and exit from the capital, and what happens to shares on a departure or a dispute. It is neither compulsory nor published at the RCS. A lawyer drafts it, consistent with the company's articles.
Definition
A shareholders' agreement is a contract concluded between all or some of the shareholders of a company, outside the articles of association. It binds them among themselves, remains confidential and supplements the legal and statutory rules on managing the company and transferring its shares. In an SA it is also called a shareholders' pact.

| Enforceable | Against third parties and all shareholders | Against the signatories only |
| Amendment | Shareholders' meeting decision, often by notarial deed | Agreement of the signatories as provided in the agreement |

- Pre-emption: priority for shareholders to buy the shares of a shareholder who wants to sell.
- Tag-along and drag-along: right to follow a majority sale, or obligation to sell with the majority.
- Departure of an active shareholder: buy-back of their shares at a price set according to the circumstances of the departure.

What we do, and what we do not do
Business Registration is not a law firm and does not draft shareholders' agreements. We prepare the questionnaire, coordinate drafting by a partner lawyer and ensure consistency with the articles and the incorporation timetable. The content below is general and does not replace legal advice tailored to your situation.
Agreement and articles: avoiding contradictions
Some rules take effect against everyone only if they appear in the articles. In a SARL, for example, the law makes the transfer of shares to a non-shareholder subject to approval by shareholders representing at least three quarters of the capital, unless the articles lower that threshold to one half. An approval or pre-emption clause that must bind the company therefore belongs in the articles, with the agreement setting out the details.
The agreement has the advantage of confidentiality: buy-back price, personal commitments, exit timetable. Its drawback is its reach: it binds only its signatories, and a breach is in principle settled by damages. This is why the lawyer often drafts the agreement and the articles together.
For the articles themselves, see SARL articles of association in Luxembourg or SA articles of association in Luxembourg.

Frequently asked questions
Is a shareholders' agreement compulsory in Luxembourg?
No. No rule requires one. It becomes useful as soon as there are several shareholders, especially when one of them works in the company, when contributions are unequal or when an investor joins the capital. It settles in advance situations the articles do not cover, such as the departure of an active shareholder.
Must the agreement be filed with the RCS?
No. Unlike the articles, a shareholders' agreement remains a private contract. It is neither filed with the RCS nor published in the RESA, so it can contain confidential items such as price formulas. Third parties, including creditors, have no access to it.
What happens if the agreement contradicts the articles?
The articles bind the company and third parties. The agreement binds only its signatories. A contradiction creates a risk of dispute and can strip a clause of effect. The lawyer checks that the two documents are consistent. When the articles change, the agreement must be reread, and vice versa.
When should the agreement be signed?
As early as possible, ideally at incorporation, while the shareholders agree. Negotiating an agreement after a first disagreement is much harder. It can also be signed when a new shareholder joins, who then adheres to the existing agreement or negotiates a new one.
Does a sole shareholder need an agreement?
No, an agreement requires at least two shareholders. A sole shareholder who plans to open the capital later can, however, prepare articles suited to that change, for example with an approval clause or majority rules designed for several shareholders. The articles can then accommodate new shareholders without being redrafted.
