Thomson Reuters Expands CoCounsel Legal to the UK
Thomson Reuters (Nasdaq/TSX: TRI), a global content and technology company, has announced the launch of CoCounsel Legal in the UK, an agentic AI solution purpose-built for legal professionals.
Featuring Deep Research on Westlaw Advantage and Practical Law, CoCounsel Legal is a next-generation AI solution that brings together legal research, essential workflow automation, intelligent document search, and AI-powered legal assistance in a unified solution.
After successfully introducing CoCounsel Legal in the US, Thomson Reuters is uniquely positioned to deliver this agentic AI solution to the UK. Thomson Reuters AI technology, CoCounsel, provides the components needed to complete complex, multi-step professional work: advanced reasoning models, authoritative content, deep subject-matter expertise, and native integration.
“We knew we needed to bring in a GenAI legal assistant to help us deliver the best possible service we can for clients,” said Sam Dixon, Chief Innovation Officer at Womble Bond Dickinson. “For us, the fact that CoCounsel had the ability to lean on the Westlaw and the Practical Law content was beneficial. And it already integrates with a lot of the rest of our legal tech stack, such as HighQ.”
Unlike AI copilots that sit beside the work, CoCounsel Legal is embedded in it – built to drive real outcomes in litigation, transactional work, and regulatory analysis. It represents the foundation for how professional AI will be delivered across law firms and legal departments in the future. It also seamlessly integrates with Microsoft 365, document management systems, and Thomson Reuters HighQ.
"Professional-grade AI is fundamentally changing how legal work gets done, and with CoCounsel Legal, we're delivering enterprise-ready agentic AI that helps UK law firms and legal departments future-proof their practices," said David Wong, Chief Product Officer at Thomson Reuters. "This isn't just about efficiency – it's about empowering legal professionals with AI that reasons through complex problems, integrates seamlessly into existing workflows, and scales across entire organisations while maintaining the trusted, authoritative foundation our customers depend on. More than convenience, it's about delivering real value to our clients and their work."
Deep Research Firsts in the UK
Deep Research in CoCounsel is the legal industry’s first professional-grade agentic AI research capability, and its UK launch marks several deep research firsts:
- Practical Law’s version debuts globally, launching first in the UK and the US in February.
- The new Westlaw Advantage brings the professional-grade agentic AI research capability to UK legal content.
- A unified experience combines both content sets into a single platform, delivering comprehensive results across practice areas without requiring users to navigate between systems.
Deep Research in CoCounsel is built to reason, plan, and deliver comprehensive legal research grounded in Westlaw and Practical Law content. It enables legal professionals to hand off full research questions to an AI that not only understands the assignment – it explains its process, sources its answers, and builds the argument foundations, with human oversight. Additionally, it generates multi-step research plans, traces its logic with transparent reasoning and delivers structured, Westlaw and Practical Law citation-backed reports.
Tabular Analysis Transforms Document Review
Tabular Analysis, launched in beta in November and now available in CoCounsel Legal in the US, is an enhanced process for high-volume document review. Users can upload extensive collections, processing up to 10,000 documents and 100 questions, and Tabular Analysis presents results in a dynamic table format that can be filtered and sorted to meet specific needs.
