Thomson Reuters Debuts CoCounsel Legal in the UK
On January 26, 2026, Thomson Reuters officially announced the launch of its innovative AI-powered platform, CoCounsel Legal, in the United Kingdom. This advanced legal assistant combines legal research, workflow automation, and AI-driven support to help professionals streamline their practice. The UK rollout introduces a powerful new capability—deep research functionality integrated with trusted platforms Practical Law and Westlaw.
CoCounsel Legal made its debut in the United States last year, and its enhanced UK version now sets the stage for a broader global rollout beginning in February 2026. The new features aim to provide lawyers with unparalleled support in conducting comprehensive legal research, offering transparent reasoning, and generating detailed, citation-backed reports.
Advanced AI with Deep Legal Research
The core strength of CoCounsel Legal lies in its agentic AI, designed to reason, plan, and execute sophisticated legal research. By leveraging the extensive databases of Westlaw and Practical Law, the platform allows legal professionals to submit complete research questions to the AI. The system then processes the queries, outlines its methodology, cites relevant legal sources, and builds arguments with full transparency.
One of the standout features is the generation of multistep research plans. These plans not only track the AI’s logic but also provide users with a clear understanding of how conclusions were reached. This ensures that human oversight remains integral, supporting informed decision-making and compliance with legal standards.
UK Clients Already Seeing Benefits
Several UK law firms have participated in the beta testing of CoCounsel Legal, including Womble Bond Dickinson. The firm’s Chief Innovation Officer, Sam Dixon, emphasized the value of integrating generative AI into their legal services. “We knew we needed to bring in a GenAI legal assistant to help us deliver the best possible service we can for clients,” Dixon stated. “For us, the fact that CoCounsel had the ability to lean on the Westlaw content and the Practical Law content was really beneficial. And it already integrates with a lot of the rest of our legal tech stack, such as HighQ.”
By integrating seamlessly with platforms like Microsoft 365 and various document management systems, CoCounsel Legal fits naturally into existing legal workflows. Its adaptability and compatibility with current legal tech infrastructures make it an appealing option for firms aiming to modernize their operations.
Exploring Agentic Capabilities
Thomson Reuters plans to release a detailed interview with Emily Colbert, Senior Vice President of Product Management, to further illuminate the platform’s features. The discussion will provide an in-depth look at the agentic capabilities of CoCounsel Legal and share key insights gained from the beta testing phase.
Early feedback from legal professionals suggests that CoCounsel Legal not only enhances productivity but also reduces the time needed for complex legal research. With its ability to trace logic and cite authoritative sources, the AI assistant is shaping up to be a trusted partner in legal analysis and documentation.
Global Rollout on the Horizon
While the UK launch is a significant milestone, Thomson Reuters has set its sights on a broader international rollout. Following the UK debut, the enhanced version of CoCounsel Legal will become available in the United States in February, with further expansion planned across global markets.
As legal professionals worldwide grapple with increasing demands for efficiency and accuracy, tools like CoCounsel Legal are poised to transform the landscape. By offering a combination of cutting-edge AI, trusted legal content, and seamless integration, Thomson Reuters is setting a new standard in legal technology innovation.
