Stewart is one of the country’s leading silks dealing in highly complex financial cases. His experience and expertise in jurisdictional issues are unparalleled. He is the ‘go to’ silk in any case with a French element.

Overview

Stewart specialises in ancillary relief, civil partnership and cohabitee disputes as well as Inheritance Act claims. His cases involve significant wealth and complex financial arrangements, often with an international dimension and/or involving tricky jurisdictional disputes. He is bilingual in French and English and has a particular interest in cross-channel cases. He is regularly instructed by corporate clients and trustees both to advise and to represent them in proceedings. He also routinely drafts pre- and post-nuptial agreements, again often involving multiple jurisdictions.
