Home ○ Dispute Resolution

We work with our clients to resolve disputes by whichever means is the most appropriate in the circumstances: litigation, arbitration, mediation or negotiation. ArsLegem’s Dispute Resolution practice provides clients with integrated and innovative legal advice in all major substantive areas of the law, from commercial disputes to insolvency proceedings, from IP disputes to employment related litigation, we cover all of that. Additionally, disputes with tax and customs authorities constitute a large portion of our work. We have great experience in guiding our clients through the tax dispute process with the goal of achieving successful resolutions as efficiently as possible.

Our multidisciplinary, trial-ready approach helps clients manage risk at every stage of the dispute resolution process. We analyse the case, collect evidence base, develop litigation strategy, and represent our clients before all courts and administrative authorities in Ukraine, including the Highest Commercial Court of Ukraine, Highest Administrative Court of Ukraine, and the Supreme Court of Ukraine.

We have experience acting under the major arbitration rules, such as ICSID, UNCITRAL, ICC, LCIA, SCC, VIAC, AAA/ICDR, WIPO as well as ad hoc arbitrations. We successfully represent our clients before arbitral institutions under the auspices of the Ukrainian Chamber of Commerce and Industry (UCCI) and have vast experience in advising the first-rank international law firms and co-operating with them in various Ukraine-based aspects pertaining to disputes resolution in international litigation and arbitration.
