What CMS Legal Services does

CMS Legal Services is an international law firm network comprising 22 independent member firms operating across 50+ countries through 90+ offices, with a global headcount of 10,000+ staff including 7,200+ lawyers. The firm delivers full-service legal advisory organized along two axes: 12 sector specializations (Aerospace & Defence, Automotive & Mobility, Consumer Products, Energy & Climate Change, Funds, Hospitality/Travel/Leisure, Infrastructure & Projects, Insurance, Life Sciences & Healthcare, Private Clients, Private Equity, and TMC) and 12 practice areas (Antitrust/Competition, Banking & Finance, Commercial, Corporate Crime/Compliance, Corporate/M&A, Dispute Resolution, Employment, ESG, Intellectual Property, Public Procurement, Real Estate, and Tax). Marquee clients include Equinor, Repsol, Nestle, Barilla, Diageo, Amazon, New Balance, Accor, Iberostar, Noreco, UK Ministry of Defence, Aviva Investors, and PATRIZIA, spanning enterprise corporates, financial institutions, governments, and high-net-worth individuals. Revenue is generated through professional-services billing on legal advisory, transaction support, dispute resolution, and regulatory compliance matters, with multi-year engagement cycles and quote-based pricing tied to matter complexity and jurisdiction.

The firm supplements traditional legal services with a proprietary legal-tech stack, including CMS Expert Guides, the Legal Updates subscription service, the Digital Regulation Tracker, and specialized tools such as CMS ESG Compass, CMS Dawn Raid Assistant, CMS Green Trail, CMS CSDDD Navigator, CMS Public Procurement Remedies Toolbox, AI Navigator, and CMS Evidence (a bespoke generative-AI document-review tool for regulatory compliance). Distribution is direct, through engagement letters with corporate, financial, and government clients; there are no intermediaries or resellers. Marketing centers on thought leadership via expert guides, publications (notably the annual CMS European M&A Study), webinars, podcasts, and a Personalized Updates subscription service. Coordination is led from London by Pierre-Sébastien Thill (Chairman of the Executive Committee), Stephen Millar (Executive Partner), and Isabel Scholes (Executive Director), with sector groups co-headed by senior partners across each major jurisdiction.
