Contentious Trusts

We represent trust corporations, high net worth individuals, individual trustees and beneficiaries, often dealing with novel points of law and creating new and innovative solutions to fit the needs of our clients. We work as a global team and, given the international scope of settlors, investments and assets, clients benefit from the knowledge and depth of experience of our people around the world.

Director and Shareholder Disputes

Thanks to the depth of our experience and the resources of our team, we've acted on some of the largest pieces of litigation brought against directors offshore. We're well placed to deal with the 'bet the farm' proceedings that can occur in these type of disputes and have represented parties involved in intra-company disputes, including executive, non-executive and independent directors, majority and minority shareholders, companies and liquidators. We understand that shareholder disputes are often not black and white and our team finds innovative and commercial alternatives to those which the Court may offer – taking a collaborative approach with our clients to ensure that the right result is achieved.
