The $572 billion multi-family office adds FortCay's 14 ultra-wealthy families and $2.6 billion in assets to establish first presence in the offshore financial center.
Corient acquired FortCay Family Advisory, a Cayman Islands wealth manager serving 14 ultra-high-net-worth families with approximately $2.6 billion in client assets, the firm announced September 23. The acquisition establishes Corient's first presence in the Cayman Islands and extends the multi-family office's reach into a jurisdiction where complex family wealth is structured and administered.
FortCay was founded by Billy Harty and Matt Houghton. The firm provides wealth management, estate planning and family office services to its ultra-wealthy clientele. Harty will continue as managing director following the acquisition.
Corient manages approximately $572 billion globally and employs more than 2,700 people across more than 300 partners. The firm was established in 2020 and operates as a private partnership structured similarly to professional services firms. Kurt MacAlpine serves as founding partner and chief executive officer.
The Cayman Islands is a leading international financial center and hub for private wealth. Many of Corient's clients live, work and invest across borders, MacAlpine said. Establishing a presence in Cayman deepens the firm's ability to serve them, he said.
Corient's partnership model gives clients access to expertise and resources across the entire firm rather than depending on a single advisor. The structure operates with complete fee transparency and a client-first approach, the firm said.
Harty said Corient shared FortCay's standards and commitment to putting clients first. The partnership model gives FortCay access to the depth and scale of a global firm while creating new opportunities for clients, he said.
The Deployment Angle
Family Office Real Estate Daily Desk · our analysis, not the source's
This acquisition reveals the structural advantage Cayman offers for complex wealth: tax neutrality, asset protection trusts, and a stable common-law jurisdiction for holding structures. Families with international assets, multiple passports, or succession concerns across borders should evaluate whether their wealth is optimally domiciled. If your primary advisor cannot coordinate Cayman trustees, local counsel, and onshore tax planning, you are paying for siloed service.
The economics are instructive. FortCay serves 14 families with $2.6 billion in assets, implying an average client relationship of $186 million. That concentration suggests these are not passive account holders but families with operating businesses, investment portfolios, and governance needs that demand year-round coordination. The partnership model Corient offers—shared expertise, no single-advisor dependency—directly addresses the principal-agent problem inherent in private wealth: misaligned incentives and knowledge hoarding.
For families considering offshore structuring, the deployment question is whether to work with a single-jurisdiction specialist like FortCay or a global platform like Corient. The former offers depth and personal relationships; the latter offers breadth and continuity if a key advisor leaves. This deal shows the appeal of combining both. Families already using Cayman vehicles should audit whether their advisors collaborate effectively across jurisdictions or operate in silos that increase cost and risk. If coordination fails, consider consolidating under a single multi-family office with demonstrated cross-border capability.
