Trusts & Fiduciary

We work closely with trust and fiduciary businesses and their clients to build strong relationships based on trust, confidence and a deep understanding of their priorities and needs. We have an extensive range of experience in terms of particular products or service lines, including pensions and Shariah, and many of the team have worked in the other international off and onshore jurisdictions prominent in the world of wealth management. We have associated skills in dispute resolution, risk and regulatory, and image protection. We ensure that thought has been given to the composition of the team on every piece of work we do, and use our mix of skill and experience effectively.
