About

Practice Areas

Geoff’s experience consists entirely of dealing with complex litigation relating to trusts and estates, often with an offshore element. He has experience with cases involving the UK, Bermuda, US, Channel Islands, Cayman Islands, British Virgin Islands and Hong Kong, among other jurisdictions. Geoff is equally at ease dealing with purely domestic matters.

Unusually for a litigator, Geoff acts as a trustee, which gives him a first-hand view of the issues facing trusts and trustees. Geoff has also been appointed as an expert witness in the High Court of England and Wales on matters relating to cross-border litigation.

Career

Geoff joined Stewarts in 2020. He originally qualified in San Francisco and cross-qualified as an English solicitor in 2008. On moving to London, he was at Withers and then at Bircham Dyson Bell, where he headed up the will and trust disputes team.
