KLEYR GRASSO > The Legal 500 Rankings
Luxembourg > Dispute resolution Tier 1
Litigation underpins much of KLEYR GRASSO’s work in Luxembourg, whether through formal proceedings or in a pre-litigation and risk management context. The size of the team, which includes four partners, ensures that it has the strength-in-depth to advise across a wide range of disputes, and to provide clients with a degree of individual partner specialisation. The ‘very strategic’ Marc Kleyr continues to handle a significant amount of high-profile litigation matters, alongside his duties as managing partner of the firm, and is appreciated for his ‘compassion’ and ‘outstanding perseverance’, including in complex shareholder disputes. ‘Fully aware of the procedural rules and recent Luxembourg case law’, in part due to her role as a member of the Luxembourg Bar Commission on civil procedure, Donata Grasso handles a range of complex domestic and cross-border disputes and is noted, in particular, for her ability ‘to analyse legal problems and to find practical solutions’ in relation to business disputes. Other recommended practitioners include Rosario Grasso, who combines ‘good judgement paired with professional aspiration’, for clients engaged in white-collar disputes; ‘top drawer litigator’ Pascal Sassel, ‘who really knows his stuff’ as it relates to financial services disputes; and François Collot, whose principal focus is on real estate and construction cases.Practice head(s):
