Testimonials

Collated independently by Legal 500 research team.

The law firm’s extensive experience was evident from the start — they immediately knew how to proceed and clearly outlined the possible outcomes in advance. Their responses are always very quick, and their work and communication are consistently professional.
Eszter Ritter's deep legal expertise is a tremendous asset, and we were consistently impressed by her exceptional responsiveness. Her inquisitive nature drives her to thoroughly understand every facet of a case, which allows her to devise creative, yet legally sound, solutions to complex problems. This approach is especially effective in her dealings with the Hungarian Competition Authority, where she navigates challenging regulatory matters with remarkable skill.
We have been working with Ivan Solyom for many years, and his expertise and dedication have been invaluable to us and our clients. He consistently delivers top-notch legal advice, always with a quick and pragmatic approach. Similarly, although we cooperate with Eszter Ritter to a smaller extent, in my opinion she is an excellent lawyer and she mirrors Ivan's efficiency and practical mindset.
Experienced partners and senior lawyers. Our law firm's antitrust team is going to Hungary.
Dr. Ritter Eszter and Dr. Nagy B. Dávid provided swift and comprehensive support. They communicated with ease, explained the situation clearly to colleagues without a legal background, and worked together in a highly dynamic and efficient way.
Drawing on its unique past as the former Budapest office of Clifford Chance, the team offers sophisticated and commercially astute services. These services effectively blend international best practices with profound local regulatory knowledge. What makes this practice unique is the high level of partner involvement. Direct and easy access to the firm's leading experts guarantees strategic oversight on all crucial mandates.
