I specialise in commercial litigation and have significant experience of acting for financial services businesses in contractual disputes, trusts, insolvency and regulatory/compliance matters. I have a particular interest in commercial or trust disputes involving private international law aspects and cross-border disputes (particularly those which raise issues of jurisdiction and enforcement of foreign judgments).
