Our team is filled with first-chair trial, investigations, and arbitration lawyers who regularly lead some of the world’s largest matters – often with stakes exceeding US$1 billion. We combine this courtroom strength with deep sector and regulatory insight, bolstered by strong ties to our Global Regulatory practice. Whether the issue is commercial litigation, international arbitration, investigations, or employment disputes, we bring a strategic, business-minded approach to every engagement.

We are trusted advisors in the face of today’s most pressing institutional risks: rapidly evolving regulatory regimes in the United States, United Kingdom, EMEA, and APAC; the accelerating pace and complexity of AI and digitalization; economic uncertainty driven by shifting political policies, tariffs, and sanctions. Our ability to anticipate and respond to these forces is what sets us apart.

Our legal and business acumen – supported by cutting-edge technology and a deep bench across technical disciplines – gives us the insight and intuition to craft innovative strategies and deliver exceptional outcomes. Collaboration is not just a value – it’s a daily practice that defines how we work across borders, disciplines, and industries.

At Hogan Lovells, we don’t just resolve disputes. We help our clients stay ahead of them.
