Cone Marshall

Company Profile

Cone Marshall is a multifaceted fiduciary services group, providing fiduciary, administrative and accounting solutions for the structuring, protection, planning and succession of wealth. For more than two decades, the firm has supported internationally minded families in safeguarding assets, building robust governance frameworks and ensuring smooth transitions across generations.

Founded by Mr Geoffrey Cone in 1998 as a law firm in New Zealand, Cone Marshall has evolved into a recognised global leader in fiduciary services. From its original offices in New Zealand, Switzerland and the United States, the group has expanded to include a presence in Brazil, the British Virgin Islands, Hong Kong, Italy, Paraguay, San Marino, Singapore, Spain, the United Arab Emirates, the United Kingdom and Uruguay. With this international footprint, Cone Marshall is positioned to support clients across all major wealth hubs worldwide.

The firm works closely with an extensive network of professional advisers, as well as banks, trustees and other institutions. A hallmark of Cone Marshall’s expertise lies in resolving conflicts of law across multiple jurisdictions, achieved by coordinating the right advisers in each country to deliver seamless cross-border solutions.

Cone Marshall operates as an independent fiduciary services group and does not maintain formal partnerships or affiliations with other legal or financial service providers. This independence allows the firm to collaborate freely with a wide range of trusted professionals in service of each client’s best interests.

At the heart of Cone Marshall’s practice is a discreet, personal and culturally sensitive approach. The firm is dedicated to supporting each client’s unique goals and circumstances, cultivating strong and lasting relationships with families and their advisers. This combination of global reach, technical expertise and a deeply personal ethos has earned Cone Marshall its reputation as a trusted partner to clients and institutions around the world.

The Cone Marshall Group has an office situated in Mayfair, London, led by Matthew Gamman, managing director, who can be contacted directly through his profile to learn more of their global offering.
