The firm will provide specialist legal advice to Team England including on sponsorship and membership agreements, sports law, property and employment law matters.
The partnership was confirmed at the end of the 2015 Commonwealth Youth Games in Samoa, where England won the second highest number of medals. Shakespeare Martineau will see England through the 2017 Commonwealth Youth Games and to the 2018 Gold Coast Commonwealth Games.
Client and markets director Joanna Thornell said: “We are delighted to be at the beginning of a partnership between two teams who share the same winning spirit and focus on supporting talent to achieve their potential.
“Everyone here has a great sense of pride and excitement to be working with Team England – a team that, after all, reflects just how much can be achieved by a diverse and varied group of individuals all focused on one goal. We cannot wait to get started.”
