When a single family office starts to make sense
Built on Chapter 1 of The Single Family Office by Richard C. Wilson. Full chapter text: FamilyOffices.com.
One of the most common questions I get is simple: how much wealth do you need before a single family office is worth it? Many people expect a single number. I avoid giving one, because the right answer depends less on the size of the fortune and more on its complexity and on what the family wants the office to do.
Why a single number misleads
Two families with the same net worth can need very different things. One might hold most of its wealth in a public stock portfolio, live in one country, and have two children. Another might own an operating company, real estate in several states, private deals, and a foundation, with three generations involved. The second family needs far more coordination, even with the same total wealth.
Costs also vary widely. A lean office with one executive and outside advisors costs much less than a full team with in-house investment staff. So the break-even point moves depending on the model.
The real tests
Instead of a number, I suggest families look at a few tests.
Complexity. How many entities and private holdings does the family have? The more there are, the more value a dedicated office adds.
Control. Does the family want a direct say in investment decisions, or is it happy to hand that to a bank or advisor?
Direct investing. Does the family want to buy companies or co-invest in private deals? That usually calls for a dedicated team.
Privacy. Does the family want its affairs handled by people who work only for them?
Generations. Are several generations or branches involved, each needing services and a voice?
Cost versus value. Will the office save enough in fees and avoided mistakes to justify what it costs?
Signs a family is not ready yet
- Most wealth sits in one simple portfolio.
- The family is happy with its current advisors.
- No one wants to oversee an office or its staff.
- There is little interest in direct deals or active governance.
In these cases, a multi-family office or a strong private bank may serve the family well for now.
The middle options
Many families sit in between. For them, a lean office is often the right first step. One trusted executive coordinates outside advisors, runs reporting, and keeps the family organized. This gives much of the control of a full office at a fraction of the cost. Later, if wealth or complexity grows, the office can add staff.
Another option is a multi-family office that offers dedicated service teams, giving a near single-family experience while sharing costs.
How to decide
List what you need. Write down every service the family needs today and expects in five years.
Price the options. Get estimates for a multi-family office, a lean office, and a full office.
Count the hidden value. Include savings from better tax planning, fewer mistakes, and avoided fees.
Talk to peers. Families who made this choice a few years earlier can share what they would do differently.
Decide, then review. Pick a model and revisit it every few years.
A note on timing
The decision often comes after a liquidity event, when wealth suddenly becomes liquid. That is a good moment to review the options, but not to rush. Taking a few months to decide is wise.
What to take from this
- There is no single wealth number that justifies a family office.
- Complexity and control matter more than size.
- A lean office is often the right first step.
- Price each option, then review the choice every few years as the family and its wealth change.
