How we help
The right technology lawyer for your Luxembourg file
Technology businesses operating in or from Luxembourg work inside a continental civil-law system that is layered with European rules. Whether you are negotiating a software licence, structuring a managed-services agreement, dealing with a platform’s data flows or trying to recover a failed IT project, the practical question is the same: who knows both the technology and the way Luxembourg’s courts, Bars and procedure actually operate? Describe your situation once, free of charge, and we match you with a technology lawyer in Luxembourg whose practice fits your specific matter. There is no obligation to instruct, no fee for the introduction, and no need to know in advance which court, which language or which rules apply to your file.
Luxembourg in practice
How technology matters work in Luxembourg
Luxembourg combines a Civil Code descended from the French Napoleonic Code with a trilingual court system and one of the densest concentrations of cross-border businesses in Europe. For a technology client, the essentials are who may advise you, where a dispute would be heard, what language the file will run in and what it will cost.
Who may advise you
Only lawyers registered on the roll of the Barreau de Luxembourg or the Barreau de Diekirch may practise law in the Grand Duchy, and lawyers are the only professionals admitted to give legal consultations as a habitual paid activity. They are bound by professional secrecy protected by criminal law — a decisive protection when your instructions involve source code, security incidents or confidential commercial terms.
Where technology disputes are heard
Civil and commercial technology disputes follow the ordinary judiciary. Claims of lesser value go before the three Justices of the Peace, which hear matters up to EUR 10,000 and up to EUR 15,000 in certain cases, while the two District Courts in Luxembourg and Diekirch take everything not expressly assigned elsewhere. In commercial matters parties may appear in person or through a lawyer without the ministère d’avoué.
Language of procedure
Luxembourg has three administrative languages — French, German and Luxembourgish. Procedural documents must be drafted in French, while hearings may be conducted in any of the three and court-provided translation is paid for by the State. A working command of French therefore remains essential for litigation, even where the underlying technology contracts are drafted in English.
What litigation costs
No court fees (frais de justice) are payable to the State to bring proceedings in Luxembourg, so the most substantial cost of a technology dispute is lawyers’ fees, alongside notaries, bailiffs and experts. The losing party may be ordered to pay costs, but each side in principle bears its own lawyer’s fees unless the court awards a procedural indemnity.
How fees are set
There is no binding official tariff for lawyers’ fees. Under Article 38 of the Law of 10 August 1991 on the legal profession, the lawyer sets the fee by agreement with the client, taking into account the importance and difficulty of the matter, the result obtained and the client’s financial situation. Disputes over fees may be brought before the Bâtonnier.
Cross-border teams and tax
Technology businesses in Luxembourg frequently operate with cross-border teams. For direct taxes, a resident taxpayer is taxed on worldwide income, whereas a non-resident is taxed only on Luxembourg-source income, and holding a residence permit does not by itself create tax residence. Bilateral treaties following the OECD model eliminate double taxation by exemption or by credit.

Common situations
When technology projects need a lawyer
Most technology files in Luxembourg are not courtroom dramas at the outset. They are contracts, deadlines and decisions that become expensive when they are handled without local legal input.
A supplier or client has stopped performing
A licence, hosting or development agreement breaks down, invoices stop being paid and both sides start arguing about scope, milestones and liability. You need to know what your contract actually allows before you write the next email.
Your data or security arrangements are questioned
A partner, investor or authority raises questions about how personal data is processed, who the controller is and what happens after an incident. Confidential advice from a lawyer bound by professional secrecy is often the first practical step.
You are expanding into Luxembourg
Setting up an entity, hiring cross-border staff, signing with a public body or litigating in French procedure all create obligations that are easier to plan than to repair. Local counsel helps you choose the right structure from the start.
Why use our matching
Matched with the right Luxembourg technology lawyer
We are not a law firm and we do not give legal advice. We connect your matter with lawyers who already work on this type of file.
Practice-area fit
Your request is routed by the type of technology matter you describe — contracts, data, disputes, regulatory questions or corporate structure — rather than by whoever answers the phone first.
Local knowledge of two Bars
Luxembourg has no single national bar: the Barreau de Luxembourg and the Barreau de Diekirch are separate, independent bodies. We match you with lawyers registered on one of those rolls.
Clear on language
Because procedural documents in Luxembourg must be drafted in French while hearings may be held in three languages, we look at whether the lawyer can run your file in the working language you need.
Costs understood upfront
There is no binding official tariff for lawyers’ fees in Luxembourg. Matched lawyers explain their fee basis and whether legal aid could be relevant before you commit to anything.
Also available in
Technology lawyers across Europe
The same free matching service covers technology and digital law matters in other European jurisdictions, whether your contract, your entity or your counterparty sits there.
Frequently asked questions
Practical questions about technology law in Luxembourg
Do I need a technology lawyer in Luxembourg if my contract is governed by foreign law?
Not always, but it is often worth checking. The company, the data, the employees or the assets may still be in Luxembourg, and Luxembourg courts apply their own procedural rules. A technology lawyer in Luxembourg can tell you which forum and which language your file would actually involve.
Can a technology lawyer in Luxembourg advise on data protection questions?
Yes, in the sense that lawyers registered with the Barreau de Luxembourg or the Barreau de Diekirch are the only professionals admitted to give legal consultations as a habitual paid activity in the Grand Duchy. They are also bound by professional secrecy protected by criminal law, which suits sensitive technical information.
Where would a dispute over an IT project be heard in Luxembourg?
Smaller civil claims go before one of the three Justices of the Peace, which hear matters up to EUR 10,000 and up to EUR 15,000 in certain cases. The District Courts in Luxembourg and Diekirch take civil and commercial matters not assigned elsewhere, with appeal to the Court of Appeal.
Must I be represented by an avocat à la Cour in a technology dispute?
Before the District Courts in civil matters, the Court of Appeal, the Court of Cassation and the administrative courts, the ministère d’avoué is in principle mandatory, which means an avocat à la Cour. In commercial matters, however, parties may appear in person or be represented without that requirement.
In which language will my Luxembourg file run?
All procedural documents must be drafted in French, but hearings may be conducted in French, German or Luxembourgish, and court-provided translation is paid for by the State. In practice, working command of French matters for litigation even where the contracts themselves are in English.
How much does a lawyer cost in Luxembourg, and is legal aid available?
There is no binding official tariff: fees are agreed between lawyer and client under Article 38 of the Law of 10 August 1991, and disputes go before the Bâtonnier. Legal aid (assistance judiciaire) exists for natural persons of insufficient means, total or partial, and covers lawyer, notary, bailiff and translator fees.
