Our story
We were founded in London in 1822 by William Henry Ashurst, a prominent anti-slavery campaigner. His commitment to leading the field and inspiring change has been the consistent thread through the firm’s evolution to today.
In the past two centuries, we have supported global companies driving change – advising industry leaders as they have navigated increasingly complex challenges and opportunities. Today, the companies we serve operate across borders and industries, and turn to us for our ability to help them anticipate and capture opportunity, driven by our deep expertise, agility, and technological leadership.
What sets us apart in the market is how we work with our clients. We bring together global teams across legal, risk consulting, and NewLaw to deliver a seamless service and provide the incisive advice clients need.
But what truly makes us unique is our people: their passion for quality, ability to think differently, and commitment to delivering through collaboration.

FAQs
Your questions, answered.
Why did Ashurst select Perkins Coie as a partner?
U.S. expansion has long been a strategic priority for Ashurst, but we were looking for a partner with more than just a U.S. footprint – one with strengths distinct from our own, shared ambitions, and clear cultural compatibility. In Perkins Coie, we found that match.
Perkins Coie’s leading technology sector capability and deep corporate, litigation, and intellectual property expertise complements our global presence and strength in energy & infrastructure, financial services, and real estate.
Equally, Perkins Coie shares our culture defined by ingenuity, collaboration, and a willingness to challenge convention, making it an ideal partner for building a forward-looking, values-driven global firm.
Ashurst-specific questions
How will this combination deliver greater value to Ashurst’s clients?
This combination brings together two growing, elite firms of similar scale with highly complementary geographic footprints, capabilities, and cultures.
As Ashurst Perkins Coie, our greater global reach and expanded expertise means we will have the ability to do even more to help our clients solve their most pressing challenges with confidence, including access to deeper capabilities and new insights in key markets.
Ashurst Perkins Coie’s combined resources will also allow us to accelerate investments in both AI and top talent—enhancing our ability to deliver even greater insight, quality, and efficiency for our clients.
Ashurst-specific questions
The press release highlights Ashurst Perkins Coie's focus on technology, energy and infrastructure, and financial services. What does this mean for clients in other sectors?
While those identified sectors will be important to the combined firm, each of the sectors in which we operate will remain fundamental to our success, and a significant strategic focus for us moving forward.
The combined firm
How will this combination affect current Ashurst clients?
We expect to close on this combination in Q3 of 2026, subject to a partner vote at both firms and other customary conditions to closing. Until then, both firms will continue to operate independently.
Pre- and post-close, clients can expect the same personalized, relationship-driven service for which we have always been known, and as Ashurst Perkins Coie, we will be able to provide clients with deeper capabilities and new insights in key markets.
