Micro Family Office

The term "micro family office" has no formal legal definition; it describes a philosophy as much as a structure. Families who choose this model are consciously trading the comprehensiveness of a larger office for lower fixed costs and organizational simplicity. The bet is that well-chosen technology platforms and a reliable network of external advisors can replicate most of what a bigger staff would handle. Virtual family offices share some of this logic, though they typically have no dedicated staff at all.

A micro family office might consist of a single family CFO (chief financial officer — the person overseeing the family's finances) supported by an outsourced accounting firm, an outside investment consultant, and a technology dashboard that consolidates reporting across accounts. The CFO coordinates the network rather than performing every function in-house. This model is examined in detail in the lean family office structure guide.

Consider a family with a concentrated holding in a private business, a real estate portfolio, and a taxable brokerage account. One trusted professional, working with specialized outside counsel and a portfolio reporting tool, might handle coordination effectively — at a fraction of the cost of a multi-person office. This approach suits families whose wealth is significant but not yet so complex that it demands full-time specialists in every discipline.

The key confusion to avoid is equating "micro" with "informal" or "unstructured." Even a one-person office commonly operates with a clear investment policy statement, defined governance, and documented processes. Small does not mean haphazard; it means intentionally right-sized.
