Legal due diligence in Luxembourg
Legal due diligence is the complete audit of a target company before an acquisition or an investment: review of the company, its contracts, employment matters, litigation, intellectual and real property and compliance, on the basis of a data room. The firm conducts this audit and delivers a report that precisely identifies the risks.
Legal content reviewed by Maître Cora Maglo, Avocate à la Cour, Liste I du Barreau de Luxembourg depuis 2009.
Buying a company or investing in it without auditing its substance amounts to acquiring hidden risks: unbalanced contracts, emerging disputes, employment liabilities, defects in compliance or in title. Legal due diligence brings these grey areas to light before signing.
Cerno Law Firm organises the data room, audits each legal area of the target and delivers a due diligence report that prioritises the risks, their impact and the protections to be negotiated in the acquisition agreement.
The need
You are considering acquiring a Luxembourg company or investing in it and must verify its legal soundness before committing.
Without an audit, you take on liabilities, disputes and instances of non-compliance that the seller has no reason to disclose spontaneously.
The risk
Hidden liabilities, terminable key contracts, ongoing disputes, non-compliant employment matters, fragile titles, defects in regulatory compliance.
An acquisition carried out without due diligence is paid for after closing, when the risks materialise without suitable contractual protection.
The firm's involvement
Cerno Law Firm, a law firm admitted to the Luxembourg Bar, structures the data room, audits the target company across the corporate, contracts, employment, litigation, property and compliance areas, then delivers a due diligence report that identifies and prioritises the risks.
Our digital tools only simplify the gathering of documents, the qualification of materials and the tracking of the audit; they never replace the lawyer's advice, who assesses each risk and translates it into contractual protections.

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
