Family Office Basics: What They Do and When Families Use One
1 / 7
What is a family office?
- A family office is an organization that manages the financial and administrative affairs of one family or, in a multi-family office, several.
- Services usually span investments, tax and estate coordination, bill pay, insurance, philanthropy, and family governance.
- Its central value is coordination: one team sees every entity, account, and outside advisor.
- There's no legal wealth minimum, but staffing costs mean single-family offices generally serve very large fortunes.

What is a family office?
- A family office is an organization that manages the financial and administrative affairs of one family or, in a multi-family office, several.
- Services usually span investments, tax and estate coordination, bill pay, insurance, philanthropy, and family governance.
- Its central value is coordination: one team sees every entity, account, and outside advisor.
- There's no legal wealth minimum, but staffing costs mean single-family offices generally serve very large fortunes.
How are family offices regulated?
- A single-family office that meets the SEC's family office rule is excluded from the definition of investment adviser and doesn't register under the Advisers Act.
- To qualify, it must advise only family clients, be wholly owned by family clients and controlled by family members, and not hold itself out publicly as an adviser.
- Firms that advise unrelated families generally must register as investment advisers with the SEC or a state.
- Registered firms file Form ADV, which discloses their services, fees, and conflicts of interest.
How do single- and multi-family offices differ?
- A single-family office offers full control and customization, but one family bears all staffing, technology, and overhead costs.
- A multi-family office shares professionals and systems across families, lowering cost but offering less customization.
- A virtual family office uses a lead advisor to coordinate outside specialists instead of hiring staff.
- Fees and structures vary widely, so compare total cost, including underlying fund and manager fees.
What services does a family office typically provide?
- Investment oversight across entities, including manager selection, private investments, and consolidated reporting.
- Tax planning and compliance coordination across individuals, trusts, partnerships, and jurisdictions.
- Estate and trust administration alongside legal counsel.
- Risk management, insurance review, cash flow, bill pay, and philanthropic administration.
When do families consider a family office?
- Complexity is the usual trigger: many entities and trusts, operating businesses, real estate, or alternative assets.
- Several generations sharing assets need decision-making rules and governance.
- The family wants consolidated reporting and one point of coordination across advisors.
- Many families get similar coordination at lower cost from a wealth management firm working with their CPA and estate attorney.
How do families prepare the next generation?
- A written family mission statement and investment policy can align members on goals.
- Regular family meetings and financial education help heirs understand the structures they'll inherit.
- Succession plans for office leadership and trustees reduce disruption at transitions.
Key takeaways
- A family office centralizes investment, tax, estate, and administrative work for one or more families.
- Single-family offices meeting the SEC rule are excluded from adviser registration; multi-family offices generally register.
- Cost and complexity drive the choice among single, multi, and virtual models.
- Governance and succession planning matter as much as investment management.
