Family Office Structure: Roles, Org Chart and Governance That Work
By Aurelius Advisory Team · Published 2026-07-01 · Updated 2026-07-07 · 7 min read
The short answer: A family office has three layers: a legal layer (holding entities, trust or foundation, and an operating company that employs staff), a people layer (typically a head/CIO, controller, operations lead, then specialists), and a governance layer (family charter, investment policy statement, and committees). Small offices run with 2–6 people and outsource the rest; the design question is never 'what can we build' but 'what must be in-house'.
The three layers every office has
Families often conflate the legal structure with the office. Keep three layers distinct: the legal layer holds and protects assets (holding companies, trusts or foundations, SPVs); the operating layer is the management company that employs people and signs vendor contracts; the governance layer is the paper that connects the office to the family — charter, investment policy, committee mandates.
When something goes wrong in a family office, the failure is almost always in the seams between layers: an operating company acting without a mandate, or a trust whose trustees were never told what the family actually wants.
The org chart, from lean to institutional
There is no single correct chart, but there are recurring shapes. What matters is which functions are owned in-house versus orchestrated:
| Function | Lean office (2–6 people) | Institutional office (15+) |
|---|---|---|
| Leadership | Head of family office (often CIO) | CEO + CIO, separate |
| Investments | CIO + outsourced managers | In-house analysts, asset-class teams |
| Finance & reporting | Controller | CFO, fund accountants |
| Legal & tax | Outsourced | General counsel + external |
| Operations & lifestyle | Ops lead handles both | Dedicated concierge/estate staff |
| Risk & compliance | Outsourced compliance officer | In-house CCO + cyber lead |
The governance paper that earns its keep
Three documents do most of the work in a healthy office:
- Family charter — the family's values, who is served, how decisions are made, and how disputes are resolved. Morally binding, and read more often than any legal document.
- Investment policy statement (IPS) — objectives, asset allocation ranges, liquidity rules, restrictions, and who may approve exceptions. The CIO's contract with the family.
- Committee mandates — what the investment committee (and any board) may decide, its membership, quorum and reporting. Separates ownership from management before a crisis does.
In-house or outsourced: the only design question
Our default for new offices: keep control functions in-house (leadership, reporting, decision rights) and buy expertise (tax, legal, specialist investing, cybersecurity) until scale forces internalisation. An office that hires specialists before it has reporting discipline gets expensive opinions and no accountability.
Frequently asked questions
What roles does a family office need first?
The proven first three: a head of office (often doubling as CIO), a financial controller for consolidated reporting, and an operations lead. Everything else — tax, legal, specialist mandates — is better outsourced initially.
What is the difference between a family office CEO and CIO?
The CEO runs the office as a business — staff, vendors, governance, family relationships. The CIO runs the capital — allocation, manager selection, risk. In offices under ~8 people one person usually wears both hats; above that, splitting them is best practice.
Should the family office own the family's assets?
Usually not. Assets typically sit in holding entities, trusts or foundations; the family office is a management company that serves them. Mixing custody of assets with operations concentrates risk and muddies liability.
How many people work in a typical family office?
Most single family offices worldwide run with fewer than 10 staff; 2–6 is the most common band, with functions like tax, legal and cybersecurity outsourced. Institutional offices serving $1B+ commonly employ 15–30.
