Criminal Law in Luxembourg
Why a specialist criminal lawyer matters
Being questioned or charged in a criminal matter can be disorienting, especially in Luxembourg’s trilingual legal system. Procedure before the correctional/criminal chambers of the District Courts, appeals to the Court of Appeal and cassation to the Court of Cassation require a lawyer who understands not only the law but also the practical rules. Criminal Law lawyers in Luxembourg must be registered on the roll of the Barreau de Luxembourg or the Barreau de Diekirch; they are bound by professional secrecy protected by criminal law. They can assist you at every stage, from police interview to trial, and advise on legal aid if needed. We match you with a lawyer who handles criminal proceedings in Luxembourg, quickly and without charge.
Local specifics
How criminal law works in Luxembourg
Luxembourg’s criminal justice system operates within a continental civil-law framework, with French procedural rules and three administrative languages. The points below summarise the court structure, representation rules, language requirements, costs and legal aid as published by official sources.
Criminal courts
The District Courts of Luxembourg and Diekirch act as correctional/criminal chambers in criminal cases. Appeals are heard by the Court of Appeal and cassation by the Court of Cassation, both sitting within the Supreme Court of Justice in Luxembourg City. This means your matter moves through defined judicial levels.
Who may represent you
Only lawyers registered on the roll of one of Luxembourg’s two Bars may assist and represent parties before the courts of any kind. Lawyers on List I, known as ‘avocat à la Cour’, may carry out acts for which the law prescribes representation before certain courts. We match you with a lawyer admitted to the appropriate Bar.
Trilingual procedure
All procedural documents must be drafted in French, but hearings may be conducted in French, German or Luxembourgish. Court-provided translation is paid for by the State. A working command of French is essential for litigation, so your lawyer will explain the procedural steps in your preferred language.
Legal aid and costs
Luxembourg has no court fees payable to the State for bringing proceedings. Lawyers’ fees are freely agreed with the client; there is no binding official tariff. Legal aid is available to natural persons of insufficient means for the defence of their interests in criminal matters, covering lawyers’ fees.
Two independent Bars
Luxembourg has two separate Bars: the Barreau de Luxembourg and the Barreau de Diekirch. Only lawyers registered on the roll of one of these Bars may practise law in the Grand Duchy. Each Bar administers legal aid and disciplines its members; there is no single national bar.

Common concerns
Three worries we hear from clients
If any of these sound familiar, a specialist lawyer can help you move forward with clarity.
You have been summoned or charged
You do not know how the Luxembourg criminal courts operate or what to expect at the correctional/criminal chambers, Court of Appeal or Court of Cassation.
Costs worry you
You are unsure whether you will have to pay court fees, how much a lawyer will charge, and whether legal aid might cover your defence in a criminal matter.
The trilingual system feels overwhelming
The French procedural documents and the possibility of hearings in German or Luxembourgish leave you needing a lawyer who can explain every step in English.
