Ukrainian Law Firms 2025: ARIO Once Again Recognised Among Ukraine’s Leading Legal Teams

Ario Law Firm has once again been recognised among the leading players in Ukraine’s legal market by Ukrainian Law Firms. A Handbook for Foreign Clients 2025. The firm was ranked across key practice areas, while several of its partners received individual recognition.

“This is the third edition we have published since the beginning of Russia’s full-scale invasion, and it reflects not only the immense burden borne by the Ukrainian legal community, but also its remarkable transformation. What began as a struggle for survival has now evolved into a period of strategic rethinking, active institutional engagement and deep adaptation with a clear view to the future,” said Olha Usenko, Editor-in-Chief of the publication, in the foreword to the research. “Working from Kyiv, we experienced the same blackouts, air raid alerts and emotional pressure as our colleagues across the legal profession. This closeness to reality made our work not only important, but genuinely necessary and sincere.”

She added: “This edition is first and foremost about Ukrainian lawyers who remain committed to their clients, their values and their country. It is also for our readers - those who seek to understand the changes in Ukraine’s legal landscape, support the country’s recovery or become part of its future.”

Litigation

Ario Law Firm was recognised in the Advanced Practices category for Litigation.

Julian Khorunzhiy was named among notable practitioners in this area.

“Ario Law Firm’s litigation practice stands out for its deep expertise in insolvency and restructuring disputes, corporate rights disputes, property and contractual disputes, as well as banking and finance matters. The team represents clients in high-profile insolvency proceedings, including disputes between debtors and creditors.

Ario continues to represent Concord Bank in a high-profile USD 42 million dispute with the National Bank of Ukraine, in which the team secured important court decisions finding the revocation of the bank’s licence and the decision to liquidate the bank unlawful.

The firm also brings claims for damages before national courts and international institutions, including the European Court of Human Rights. One of the key precedents was the claim brought by the Lviv territorial community against the Russian Federation over missile-damaged infrastructure in 2022-2024. The case launched a broader legal campaign together with Greenberg Traurig, LLP.

Ario also represented former top managers of Ukkoopspilka Bank in a case concerning alleged losses of UAH 77 million. After years of proceedings, the case was remitted for retrial, while the firm’s lawyers argued that the charges had not been proven and were being applied retroactively.

The rise in insolvency-related disputes has further strengthened the firm’s involvement in business restructuring matters.

The firm’s substantial litigation practice is led by Partners Yulian Khorunzhiy, Andrii Fylyk and Anna Sydorovych,” the publication wrote.
