Coriats and HMSA Create a Global, Relationship-Led Trust and Fiduciary Group
Coriats and HMSA today announce the launch of Coriats HMSA, bringing together two proudly independent, director-owned and managed businesses operating multi-family office, trustee and corporate services across leading European and offshore jurisdictions, Latin America and Africa.

With roots in the British Caribbean and Switzerland, Coriats HMSA now offers clients seamless access to a wider range of jurisdictions, deeper technical capability, and a unified team built around long-term relationships rather than transactions. The new group is designed to meet growing demand from international families and entrepreneurs for trustees who can operate confidently across borders while remaining closely involved and personally accountable.
Founded in 1978, Coriats has spent more than four decades advising international families on complex cross-border structures from its Caribbean base. HMSA, which established its roots in Switzerland in 2002, brought Swiss trusteeship, governance rigour and discretion to a global client base. Together, Coriats HMSA connects these complementary strengths across Europe, the Americas, Africa and Asia-Pacific.
“Clients increasingly need trustees who understand both the regulatory reality of multiple jurisdictions and the human realities of family wealth,” said Thomas Bucknall, Senior Trust Director. “Together, these strengths allow us to offer global reach without losing the director-led, relationship-based approach that defines both firms.”
Coriats HMSA operates from key international financial centres including Geneva, Jersey, London, Ireland, the Turks and Caicos Islands, Uruguay, South Africa, Hong Kong and New Zealand. The group remains deliberately lean in each location, focusing on regulatory strength, continuity of service and clear decision-making.
