Shareholder dispute lawyer in Luxembourg
Shareholder disputes cover conflicts between shareholders: company deadlocks, abuse of majority or minority, exclusion claims, management audits and challenges to decisions. The firm defends your interests and seeks the most effective exit, negotiated or judicial.
Legal content reviewed by Maître Cora Maglo, Avocate à la Cour, Liste I du Barreau de Luxembourg depuis 2009.
A conflict between shareholders can paralyse a profitable company: blocked decisions, frozen dividends, stalled governance. The longer it lasts, the more the value of the business and the relationships deteriorate.
Cerno Law Firm assesses your position, activates the relevant legal levers (management audit, abuse of majority or minority, exclusion, withdrawal) and favours, where possible, a controlled negotiated exit rather than prolonged litigation.
The need
You are in conflict with one or more shareholders and the company is deadlocked or under threat.
You are seeking to break the deadlock, to be bought out, or to exit on good terms.
The risk
A lasting company deadlock, abuse of majority or minority, loss of value, decisions open to challenge.
A poorly managed conflict bogs down into costly litigation and devalues the business for all shareholders.
How the firm acts
Cerno Law Firm, a law firm admitted to the Luxembourg Bar, reviews the shareholders' agreement and the articles, qualifies the abuses and deadlocks, and triggers the appropriate levers: management audit, exclusion or withdrawal, negotiated exit or court action.
Our digital tools serve only to simplify the gathering of documents and the tracking of the matter; they never replace the lawyer's advice, who defines the litigation strategy and defends your interests.

FAQ
Frequently asked questions
What is an abuse of majority or minority?
An abuse of majority is a decision taken against the company's interest solely for the benefit of the majority; an abuse of minority is the unjustified blocking of an essential decision by a minority shareholder. The firm qualifies and remedies these situations.
Can a shareholder be excluded?
Depending on the articles, the shareholders' agreement and the law, an exclusion or withdrawal may be considered in certain cases. The firm checks the conditions and implements it.
What is a management audit?
A measure allowing, under certain conditions, an expert to examine certain management operations when a shareholder suspects irregularities. The firm assesses whether it is appropriate.
Is it better to negotiate or go to court?
A negotiated exit is often faster and preserves value; but the pressure of a court action is sometimes necessary. The firm chooses the most effective route for you.

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
