The decision to establish a family office is often made for the wrong reasons — or at the wrong time. Families set one up because their peers have done so, or because a wealth event has made it seem like the obvious next step. Others defer the decision for years, managing complexity through a patchwork of advisors that nobody is coordinating.
Neither approach starts with the right question: what problem are we actually trying to solve?
What a family office actually does
A family office is, at its core, a coordination mechanism. It exists to manage the intersection of family and financial complexity — the point at which the volume and variety of decisions exceed what a family can handle through its existing relationships and advisors.
Its functions typically include investment management and oversight, tax and estate planning coordination, philanthropy management, family governance support, and the personal financial affairs of family members. Some family offices also provide concierge services, education for next-generation members, and legacy planning.
None of these functions is unique to a family office. What is unique is having them coordinated by a team that serves the family's interests exclusively — not the interests of a bank, an asset manager, or an advisor who has other clients.
When you actually need one
The threshold is not a specific number. It is a level of complexity. A family office begins to make sense when the cost of not coordinating — in missed opportunities, duplicated fees, tax inefficiencies, and family conflict arising from financial opacity — exceeds the cost of running one.
For most families, this inflection point arrives somewhere in the range of substantial liquid wealth, multiple entities or geographies, more than one generation involved in financial decisions, or a combination of operating business and investment portfolio that requires genuinely different expertise to manage.
The structural choice
A family can establish a single-family office — dedicated entirely to one family's affairs — or join a multi-family office, which provides similar services to multiple families and spreads the cost accordingly. The right choice depends on the level of customisation required, the importance of confidentiality, and whether the family has sufficient scale to justify the fixed cost of a dedicated operation.
The takeaway
A family office is not a status symbol and it is not automatic. It is a response to a specific level of complexity. The question is not whether you can afford one — it is whether you can afford not to have one.
