About the Firm

Ranked as a Top 10 Global Law Firm, CMS can work for you in 34 countries and from 60 offices worldwide. 3,000 CMS lawyers offer business-focused advice tailored to your needs, whether in your local market or across multiple jurisdictions.

‘Your World First’ is our promise to you. This means we are client-centric, have world vision and are performance driven.

Client-centric - Being immersed in our clients’ industry sectors is at the heart of what we do. Our business is structured according to the industries our clients work in, delivering technically excellent lawyers who talk your language. 

We offer various added value services, including Law-Now and the Interactive Media Award winning RegZone which provide practical and timely knowledge relevant to your business and numerous webinars for training at your desk.


Law-Now is one of the best services I receive. If there is a new case, they will be the first off the mark.

To help you manage your account, we deliver bespoke reporting information for invoicing, matter progress, fees and work in progress, and we regularly win innovation awards for new technological solutions, for example for the desktop solution “Contract Quality” at the British Legal Awards and the Insurance Day London Market Awards.

World vision - We have deep local expertise in many jurisdictions and major global centres. CMS was ranked the second most global law firm in Am Law 2015 and has a track record of expanding to meet client needs, moving into countries such as Turkey and Oman to support infrastructure and energy projects.

CMS is part of organisations such as the CMS Lifesciences Asia-Pacific Network and the African Legal Network. Our lawyers are not only problem solvers but anticipate issues to allow our clients to perform better. We stay on top of the news agenda, regulatory discussions and new legislation and understand how macro trends, such as the fall in oil price, affect your business.


I am personally committed to our clients and always interested to meet with clients, hear your views and discuss ways of how we can improve what we do for you.
Penelope Warne, the Senior Partner, Chairman of the Board and Head of Energy

Performance driven - CMS takes pride in first-class execution and project management with a focus on delivering results. In 2015, we were ranked number 1 for M&A in Europe by Thomson Reuters and Bloomberg (in terms of deal count, up to USD 500m).

Our approach to service delivery is the same in all our offices, based on a common training program and a shared understanding of what our clients value. All CMS lawyers, both those we recruit and those we train in-house, are focused on providing quality advice and quality service. We are smart on the detail because the detail matters. We recruit, value and nurture top talent and through regular, independent evaluations, we identify opportunities to make improvements in our service and feed this back to our lawyers.
