During the early years, we gained considerable expertise in litigation and advisory services to local clients. Our firm then resolutely also turned towards international clients and cross-border business. 

Today, we advise local and multinational companies from all industry sectors, many of the world’s largest corporations, leading institutional investors, prestigious private equity houses and numerous other businesses, clients and professionals in almost all practice areas. 

We undertake significant client work hand in hand with leading audit and tax firms, and we regularly work on cross-border cases with foreign magic circle firms, which recommend us to their clients for the legal work and services they need in the Luxembourg jurisdiction. 

We have a highly recognised and recommended dispute and litigation team. Our litigation lawyers deal with a very large range of litigation matters, including administrative, banking, civil, commercial, corporate, competition, criminal, employment, finance, real estate, and tax, and they handle all relevant proceedings or Court applications. 

Our corporate finance & insolvency litigation team is certainly one of the strongest in the Luxembourg legal market. 

We represent local and international clients in relation to all their commercial disputes and cross-border enforcement matters, and we also regularly act as lead counsel or as an arbitrator in major local or international arbitrations.
