The team at Kinstellar Andrékó Ferenczi & Társai Ügyvédi Iroda continues to be a leader, bringing expertise to advising insurers, financial institutions and major domestic and multinational corporates involved in high-value, cross-border transactions. The firm’s client base spans such sectors as aviation, food and defence, and displays particular strength in energy, TMT, life sciences and real estate. The team’s full offering covers multi-jurisdictional M&A, joint ventures, disposals, reorganisations, restructurings and takeovers. Bolstered by the transfer to Kinstellar (in April 2024) of the German firm Noerr’s offices in Bratislava, Bucharest and Prague, as part of a non-exclusive arrangement, the team is headed by Gábor Gelencsér, who brings over two decades of experience to domestic and multi-jurisdictional M&A. Other key figures include senior counsel Ákos Nagy; capital markets specialist Áron Barta; Kármen Csenge Koller, who brings experience in negotiating sale and purchase agreements; and Bianka Kovács, who provides expertise in acquisitions and corporate maintenance. Former co-head Annamária Csenterics departed in December 2024.
