Daian is a Senior Associate within the Dispute Resolution team in the firm's Jersey office.

"'I have a results driven, methodical and resourceful approach to completing tasks and objectives in a world where business operations are increasingly multi-jurisdictional. I am good at identifying pragmatic commercial solutions and communicating effectively with clients and colleagues in order to effectively resolve disputes.'"

Daian has considerable experience of corporate and commercial litigation including domestic and cross-border insolvency, shareholder disputes, trust litigation, asset tracing, enforcing foreign arbitration awards and judgments, and seeking injunctive relief including on an emergency basis. She has appeared in the BVI Commercial Court and High Court, and at various levels in the courts of England and Wales. 

During her time in the BVI, Daian wrote a number of articles and contributed to several book chapters on BVI law. Prior to qualifying as a barrister she was a university lecturer and taught law at undergraduate and postgraduate level in a number of higher education institutions, including the Hong Kong University's School of Professional and Continuing Education. She has prepared and delivered a number of talks on her areas of expertise. Daian has a particular interest in cross-border insolvency, asset tracing and matrimonial finance including prenuptial and post-nuptial agreements.
