Criminal
Criminal law lawyer in Luxembourg
The firm defends defendants, victims and executives before the Luxembourg criminal courts: police custody, questioning, investigation, criminal court and business criminal law. You are assisted at every stage of the procedure.
Legal content reviewed by Maître Cora Maglo, Avocate à la Cour, Liste I du Barreau de Luxembourg depuis 2009.
In criminal matters, reaction time is decisive: the first hours of a police custody or a questioning often shape the outcome of the case. Being assisted early by a lawyer makes it possible to understand the procedure, exercise your rights and avoid irreversible statements.
Cerno Law Firm acts in defence as well as in representation of victims, from the filing of the complaint to the hearing, including in business criminal law where the liability of an executive or a company is at stake.
The need
You are summoned by the police or an investigating judge, placed in police custody, summoned before the court, or you are the victim of an offence and wish to join the proceedings as a civil party.
Without prompt assistance, you risk being subjected to a procedure you do not master, without knowing your rights or the consequences of your statements.
The risk
Statements made without advice, defence rights poorly exercised, detention or control measures poorly contested, the victim’s harm poorly assessed or not compensated.
A defence engaged too late, or a poorly prepared civil party claim, strongly reduces the chances of obtaining a favourable outcome.
How the firm helps
Assistance during police custody and questioning, defence before the investigating judge and the trial courts, challenge of coercive measures, civil party claim and quantification of the harm, advice to executives in business criminal law.
Cerno is a law firm admitted to the Luxembourg Bar: the digital tools serve only to simplify the collection of information and the tracking of the file; they never replace the lawyer’s advice and pleading, who alone ensures the defence of your interests.

What our clients say
Had a consultation with Me Cora Maglo about my Luxembourg Blue Card application. She explained everything clearly: the process, timeline and documents I need, and helped me with my wife’s family reunification too. Honest and practical advice. I felt confident after talking to her.Farshid Pourlatifi
J’ai beaucoup apprécié le service de Maître Maglo : son sérieux, sa sympathie, son professionnalisme et sa disponibilité. Toujours répondu rapidement et clairement, avec des conseils pragmatiques, sans pousser à des procédures longues et coûteuses lorsqu’elles ne sont pas justifiées.Nathan Wirtzfeld
Super assistance and great support! Highly recommend. All my questions were answered, Cora and her team kept me updated all the time. I will definitely reach out to them next time for my residency.Tatiana
