Located in the financial heart of London, Arnold & Porter’s UK office is a crucial bridge to an international network that spans Europe, the U.S., and Asia. Since its opening in 1997, the lawyers in our London office have been trusted advisers to a wide variety of clients — from sovereign states, financial institutions, and leading multinational and domestic organizations, to early-stage companies and individual executives.

Globally renown for our regulatory, dispute resolution, and transactional offerings, our London capabilities are further bolstered by the former government and industry experience that many of our lawyers bring in life sciences, technology, and financial services. This provides clients operating in heavily regulated industries with confidence that their most high-stakes legal needs are serviced with commercial acumen, speed, and success. The London office provides services that span 17 practice areas, and our lawyers work seamlessly with firm colleagues around the globe, together with a network of select firms across multiple jurisdictions, to provide a robust multidisciplinary approach for our clients’ most complex business and cross-border issues.

Everything we do is fueled by our core principles of exceptional client service, providing preeminent legal advice, empowering communities through public service, and building inclusivity. Pro bono is integral to who we are as a firm. Our London office routinely wins industry recognition for its high-level support to NGOs, charitable organizations, individuals, and communities in need – no matter how complex or difficult the issues may be.

Our commitment to clients is matched by our dedication to the causes and values that shape our daily lives. We prioritize training, sustainability, well-being, work-life flexibility, and continuously cultivating a culture in which all individuals are accorded dignity and respect. The benefits are not ours alone. We bring a multitude of diverse life experiences and perspectives to inclusive teams that are built to innovate and help clients thrive.
