Cross-cutting practices
CSSF regulatory lawyer in Luxembourg
Carrying out a financial sector activity in Luxembourg requires authorisation from the CSSF and continuous regulatory compliance. The firm handles authorisation files (PSF, financial sector professionals, regulated providers), structures the required governance and manages relations with the regulator.
Legal content reviewed by Maître Cora Maglo, Avocate à la Cour, Liste I du Barreau de Luxembourg depuis 2009.
The CSSF (financial sector supervisory commission) governs access to and the carrying out of financial activities in Luxembourg: without a suitable authorisation or status, the activity is unlawful, and a poorly prepared authorisation file is delayed or rejected.
Cerno Law Firm prepares authorisation applications, builds the regulatory file (governance, compliance, AML/KYC framework) and supports the exchanges with the CSSF through to the decision.
The need
You want to obtain a CSSF authorisation, a PSF status or to carry out a regulated financial sector activity in Luxembourg.
The authorisation file requires precisely documented governance, compliance and substance.
The risk
An incomplete authorisation file, refusal by the regulator, carrying out activity without an adequate status, sanctions and loss of credibility.
Defective regulatory compliance exposes you to CSSF measures and compromises the activity.
How the firm acts
Cerno Law Firm, a law firm admitted to the Luxembourg Bar, qualifies the required status, builds the CSSF authorisation file (governance, compliance, AML/KYC) and conducts relations with the regulator through to authorisation.
Our digital tools serve only to simplify the gathering of information and the tracking of the authorisation file; they never replace the lawyer's advice, who qualifies the status and defends the file before the CSSF.

FAQ
Frequently asked questions
What is a CSSF authorisation?
It is the authorisation issued by the financial sector supervisory commission allowing a regulated financial activity to be carried out lawfully in Luxembourg, for example under PSF status.
What is a PSF?
A financial sector professional, that is a regulated player subject to CSSF authorisation and supervision. The exact status depends on the activity; the firm qualifies it.
How long does it take to obtain an authorisation?
The timeframe depends on the status and the completeness of the file. The firm prepares a complete application to avoid the back-and-forth that lengthens processing.
Is a digital tool enough to build the file?
No. The tools help gather information, but the qualification of the status and the defence of the file before the CSSF are matters for the lawyer.

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
