HUNGARY Law and Practice Contributed by: Tamás Éless, Zsolt Farkas, Sarolta Szabó and Lili Bischof, Oppenheim Law Firm

Oppenheim Law Firm was part of the international law firm network for decades, first as a member of Heller Löber Bahn and later as part of Freshfields Bruckhaus Deringer. As a member of an extensive multi-jurisdictional network, Oppenheim operated in line with the most rigorous international standards. Guided by these principles, the firm has always be- lieved that its lawyers should combine deep inter- national experience and qualifications with a strong presence in foreign markets. By the end of 2005,

the firm recognised the need for a new model – one that would allow greater flexibility while ensuring the continued delivery of sustainable, high-quality legal services. In response, the firm’s management decid- ed to lay new business foundations. After a year of careful preparation, an independent commercial law firm was launched on 1 November 2007, under the historic Oppenheim name, retaining the entire team of lawyers. In an ever-changing world, Oppenheim strives to remain a point of stability for its clients.
