Dispute Resolution is a core practice at Ilyashev & Partners, consistently recognized by Chambers and The Legal 500 as one of the leading teams in Ukraine. We represent clients in complex disputes before all levels of Ukrainian courts, including the Supreme Court, and in high-profile international arbitration proceedings.

Our expertise covers the full range of commercial disputes: shareholder conflicts, contractual and corporate claims, IP litigation (trademark, patent and anti-counterfeiting), employment and labour disputes, real estate and construction, insurance, and regulatory matters. We also advise on disputes in public procurement, competition, tax, customs, and sanctions compliance, as well as large-scale insolvency and restructuring cases involving state-owned enterprises and multinationals.

We have extensive experience in international arbitration under ICSID, UNCITRAL, SCC, ICC, LCIA, and LMAA rules, handling multi-billion investment claims and acting as Ukrainian law experts abroad. Our team also excels in white-collar defence and investigations, including fraud, embezzlement, money laundering, and corporate misconduct.

Each year we manage over 500 disputes, many cross-border and highly complex. With 40+ lawyers across Kyiv, Kharkiv and Odesa, we have the scale, reputation, and local presence to deliver effective dispute resolution in Ukraine and internationally.
