Our Philosophy

At ArsLegem, we believe that legal support should be practical, transparent, and aligned with business needs. Our approach is based on:

•

Proactive Legal Security – Anticipating risks and ensuring compliance to protect businesses in both the short and long term.

•

Strong Advocacy – Providing experienced representation in disputes and regulatory matters.

•

Client Empowerment – Offering clear strategies and actionable advice, keeping clients informed and in control.

•

Transparent Pricing – Ensuring fair, predictable fee structures tailored to business needs.

Our Clients

For over a decade, ArsLegem has advised multinational corporations, leading Ukrainian businesses, and private clients. Our experience includes working with Philip Morris, Syneos Health, British American Tobacco, Multi Group, Uponor, and SCM Group, among others.

We frequently collaborate with top international law firms, such as Herbert Smith and Akin Gump, handling Ukrainian law aspects of cross-border transactions. When clients require expertise in other jurisdictions, we engage either large multidisciplinary firms or specialized boutiques, ensuring tailored and seamless legal support worldwide.

Our History

ArsLegem was founded in 2011 by Oleksandr Petrov, a former partner at a leading Ukrainian litigation and regulatory firm. In 2012, the firm evolved when Roman Kolos, previously a partner at a major CEE law firm, joined forces with Oleksandr.

From the beginning, ArsLegem was built on a commitment to partner-led service, strategic thinking, and client-focused solutions. Over the years, we have grown into a trusted legal advisor for both Ukrainian and international businesses, including Nordic companies entering the Ukrainian market.
