What a family office does (and when you need one)

When a family’s wealth grows, the question stops being “how much does it earn” and becomes “who governs it”. Accounts across several banks, real estate in different countries, stakes in one or more operating companies, insurance policies, works of art, perhaps venture holdings: each piece has its own advisor, but no one looks at the whole. This is where the family office comes in, the structure that coordinates a family’s wealth as if it were a single enterprise.

What a family office is

A family office is neither a financial product nor a bank. It is a steering function: a stable oversight point that holds together the financial side, the tax and legal side, the family’s governance and the relationship with the business of origin. Its task is not to sell investments, but to defend the family’s interests over time, coordinating external providers and preventing each from optimising its own piece at the expense of the overall picture.

The classic distinction is between two models:

• Single family office: a structure dedicated to a single family, with its own staff. It makes sense above very high wealth thresholds, because the fixed costs are significant.
• Multi family office: a shared structure serving several families and spreading the costs. It is the most widespread and accessible formula, suited to those who want coordination without building an in-house apparatus.

What it actually does

A family office’s activities revolve around a few axes.

Consolidation and reporting. The first service is a single view of the wealth: gathering data from all the banks, companies and assets, and delivering a coherent picture of how much the wealth is worth, how it is allocated and how it behaves over time. Without this foundation, every decision is made in the dark.

Wealth governance. The family office does not make investment decisions on the family’s behalf, but sets the rules: defining objectives, risk profile, allocation criteria, selection and monitoring of managers. It then checks that what happens in the accounts respects those rules.

Tax and legal coordination. A family with interests in several jurisdictions needs tax coherence. The family office coordinates advisors in the various countries, keeps compliance obligations under control and anticipates the tax impact of choices, from dividend distributions to the sale of holdings.

Generational transition. Preparing the succession is perhaps the most delicate function: structuring how and when the wealth passes to the next generation, training the heirs, preventing conflicts. A matter to be planned years ahead, not when the need arises.

Relationship between family and business. When an operating company exists, the family office oversees the dividing line between the two worlds: it separates the cash flows, clarifies who decides what and prevents family tensions from spilling over onto the running of the business.

When you really need one

It is not only a matter of figures. A family office makes sense when certain conditions apply:

• the wealth is complex and fragmented across several assets, banks and jurisdictions;
• business and personal wealth coexist, with the risk of becoming blurred;
• a generational transition is approaching or a succession is under way;
• the family is large and shared rules are needed to avoid conflicts;
• there is no internal figure able to look at the whole with continuity.

When, on the other hand, the wealth is concentrated and simple, and a single advisor is enough to keep it under control, the structure risks being oversized. The value of a family office lies precisely in complexity: the more elements there are to coordinate, the more that coordination becomes a service that pays for itself.

The risk of not having one

Those who forgo coordination pay less visible but real costs: tax decisions that are inconsistent across countries, duplicated advice, forgotten assets, and above all the absence of a steering hand at the moment of succession. It is then, when there is no one who set the rules in advance, that the most costly conflicts emerge, often irreversible in terms of family relationships.

A well-structured family office does not eliminate complexity, but makes it governable: it gives the family a single point of reference, written rules and an overall view that no single provider can offer.
