Jonathan has learned a huge amount about the laws of many countries from his experiences as a Partner with Baker & McKenzie and as Managing Director with Barclays Wealth Advisory where he was also a member of the Management Committee of the International Trusts business.

Many of his cases arise from deteriorating relationships and the complex and technical legal issues that follow in relation to taxation matters. Jonathan can quickly assess what needs to be done and is known to be intuitive and commercially pragmatic. His core practice area includes a wide-ranging discipline incorporating tax, trusts, foundations and corporate structures and succession planning.

Jonathan frequently works with business owners and wealth owners in relation to solving their cross-border legal and tax issues. He often advises on the structuring and management of capital across borders, associated immigration issues, investments in real estate or businesses in the UK, tax-related issues and multi-jurisdictional estate planning.   His practice has a particular focus on Africa, the Middle East, and the USA, which constitutes a substantial portion of his core work. Jonathan has recently been extensively involved in working on the abolition of the remittance basis and the introduction of a residency only based system in the UK.

He is ranked in Band 1 in Chambers for Private Wealth Law and the Hall of Fame in Legal 500 for Tax, Trusts and Probate. Jonathan won the 2025 Citywealth Career Achievement Award.
