Whether you’re a legal professional researching the firm’s history, a potential client seeking context on its successor, or simply curious about the architecture of modern law firms, this comprehensive guide will walk you through the rise, challenges, and lasting legacy of Davies Arnold Cooper.
The Foundations: Davies Arnold Cooper’s Early Years
Davies Arnold Cooper LLP was established in London in 1927, beginning its journey as a modest practice that would eventually grow into an international law firm with significant influence . For decades, it operated as a full-service firm, building relationships and developing expertise across multiple practice areas.
The firm carved out a reputation for itself in the competitive London legal market. By the late 20th century, Davies Arnold Cooper had established offices beyond the UK capital, including presences in Madrid, Manchester, and Mexico City, employing over 220 lawyers across its network . It secured a respectable position in the legal rankings, placing 61st in The Lawyer’s Top 100 UK law firms .
Areas of Excellence
According to legal directories Chambers and Partners and The Legal 500, Davies Arnold Cooper was best known for its work in:
-
Dispute resolution
-
Real estate
-
Insurance
-
Construction
-
Corporate law
-
Employment
-
Product liability
This specialist focus set Davies Arnold Cooper apart from general law firms, giving it a distinct identity in a crowded marketplace .
International Ambitions
The firm demonstrated early international ambition by opening its Madrid office in 1989. This proved to be a shrewd move, with The Legal 500 later describing the Spanish practice as “Spain’s leading insurance litigation practice”—a “highly specialist” outfit that “never fails to impress” .
Building on this success, Davies Arnold Cooper expanded further into Latin America, opening an office in Mexico City in 2003 . This strategic positioning would later prove invaluable as the firm’s successor continued to develop its presence throughout the region.
A Defining Moment: The Dornoch Litigation
To understand the calibre of Davies Arnold Cooper’s legal work, one need only look at its involvement in significant appellate cases. In the matter of Dornoch Ltd. & Ors v Royal and Sun Alliance Insurance Plc [2005] EWCA Civ 238, the firm represented the appellants before the Court of Appeal .
This case, heard by Lord Justice Brooke, Lord Justice Mance, and Lord Justice Longmore, concerned a complex reinsurance dispute arising from class actions against The Coca-Cola Company in the United States. The case centred on a Claims Control Clause—a standard provision that The Court of Appeal noted was “more obviously apposite to a property damage policy” than to the directors and officers liability insurance in question .
Lord Grabiner QC and David Wolfson appeared for the appellant, instructed by Davies Arnold Cooper, while Jonathan Sumption QC and Guy Morpuss appeared for the respondent, instructed by Herbert Smith . This level of representation—leading silks against equally formidable opponents—demonstrates the high-stakes nature of the litigation and the trust that clients placed in Davies Arnold Cooper.
Turbulence and Transformation
The late 1990s and early 2000s brought significant challenges for Davies Arnold Cooper. According to The Lawyer’s archives, the firm went through “an extreme period of turbulence” in 1999, making a swathe of redundancies as it cut entire departments .
Strategic Retrenchment
Facing market pressures, the firm made the difficult decision to retrench around three core areas where it had genuine strength:
-
Insurance
-
Property
-
Litigation
This strategic pivot acknowledged that being a full-service firm required scale that Davies Arnold Cooper could not sustain. By focusing on its core competencies, the firm aimed to survive and potentially thrive in niches where it could compete effectively.
Innovative Approaches
During this period, Davies Arnold Cooper also demonstrated willingness to innovate in its management practices. In 1997, the firm began putting potential new partners through “rigorous psychological tests” to assess their suitability for partnership . Managing director Nick Sinfield admitted he could not be certain of spotting partners of the future through traditional methods, leading the firm to embrace extensive psychological testing .
This forward-thinking approach to human resources was unusual for the time and reflected a firm willing to challenge convention in its pursuit of excellence.
The Merger: Birth of DAC Beachcroft
The most significant moment in the history of Davies Arnold Cooper came on 31 October 2011, when the firm merged with Beachcroft LLP to form DAC Beachcroft . This merger brought together two substantial insurance practices and created a legal business of significantly greater scale and reach.
The State of Play Pre-Merger
At the time of the merger, Davies Arnold Cooper had been struggling to grow organically, despite a 2008 takeover of KSB Law that added £8 million to the firm’s top line . The firm had a notable Latin American practice for a UK firm but remained one of the smaller City mid-sizers .
Beachcroft Stanleys, meanwhile, had entered into a merger with Bristol-founded Wansbroughs Willey Hargrave in 1999, forming a firm with core specialisms in commercial, healthcare, and insurance law . By the time of the 2011 merger with Davies Arnold Cooper, Beachcroft was in a relatively strong position, having added £10 million a year to its revenues over the previous three years .
Creating a New Powerhouse
The merger created a firm with combined revenues that would continue to grow. By 2018, DAC Beachcroft reported revenues of £348.1 million with 342 partners . While the merger was somewhat overshadowed by Barlow Lyde & Gilbert’s tie-up with Clyde & Co around the same time, it proved to be a successful combination that positioned the merged firm for future growth .

Today, DAC Beachcroft LLP stands as a leading international legal business of more than 3,000 people across offices in the UK, Ireland, Europe, Latin America, North America, and Asia Pacific .
