Arendt & Medernach
Client SatisfactionAlthough it also handles a fair amount of domestic work, including with regard to public/administrative law, Arendt & Medernach particularly ‘stands out for its ability to deal with factually and legally complex multi-jurisdictional cases’ spanning a wide range of commercial litigation relating to, inter alia, funds, asset tracing and corporate disputes. Team head Clara Mara-Marhuenda has ’outstanding knowledge of all the procedural aspects of litigation in Luxembourg‘ which she utilises to good effect for clients seeking resolution through both conventional litigation and alternative dispute resolution (ADR) means. She is also one of many in the team prepared to propose ’out of the box solutions’ without unnecessarily pushing a litigation to its limits. Sandrine Margetidis-Sigwalt also demonstrates this approach, with an ‘expertise and acuity that are instrumental in the management of complex, multi-tiered and high-stake matters’, including with regard to insurance disputes. Other key practitioners include Christian Point, whose ’highly developed analytical mind’ has ensured success for clients over the years in public and real estate cases; vastly experienced of counsel François Kremer, who utilises ADR techniques to excellent effect across a range of commercial litigation; and ‘detail-oriented yet pragmatic’ senior associate Danil Nikolaev.
