Biography
As Senior Partner of Tees much of my time is focused on the leadership and management of the business, working closely with our CEO. My role is both ambassadorial and cultural, and together with the CEO we work to ensure alignment across Tees’ Partnership and successful execution of the firm’s strategic plan.
Alongside this, I continue to work as a Private Client lawyer as part of our Cambridge team, advising on complex Estate Administration, Succession and Estate planning, Wills, Powers of Attorney and the creation and administration of Trusts. I also act as a professional Executor, Trustee and Deputy. My expertise in the Private Client sphere is recognised in the Legal 500 ‘Hall of Fame’.

Catherine Mowatt was excellent in explaining the options and consequences of various courses of action.

She kept costs to a minimum where possible and clearly defined what was chargeable and what was not. The associates were knowledgeable, understanding and kept on top of things if Catherine was temporarily unavailable.” Legal 500 UK, 2026, East Anglia – Private Client – Personal tax, trusts and probate: Cambridge
