Family office operating model: what does a well-run family office look like?

Running a family office is often understood through its most visible function: managing wealth. In practice, much of the job is about making the office itself work well.

Investments are commonly central, but the office often has a much wider role. It can support the family's day-to-day affairs and become the point through which outside advisers are coordinated. As the family becomes more complex, running that structure becomes a substantial job in its own right.

The office has to reflect the family behind it. A structure that works well for one family can be completely wrong for another with similar wealth.

A strong family office gives each family member the understanding and support to pursue their own priorities, while helping the family advance its shared vision across generations.

Running a family office well starts with defining its role. The team can then be built around the amount of work that role creates.

AUM gives some indication of the resources available to the family. The demands placed on the office depend much more on what it is actually responsible for. A family with several generations may require far more support than its net worth alone would suggest.

This favors a focused internal team in many family offices. Specialist expertise can be brought in from outside when the level of activity does not justify a permanent role.

The family office director sits across this structure and makes sure it works as a whole. Family members should also understand the important financial decisions that affect them. Education therefore belongs within the role of a good family office.

Most family offices develop gradually.

An office might initially be created to oversee investments. A few years later, it could be coordinating a property or taking responsibility for reporting. These additions often make sense individually, yet they can leave the office with a much broader role than anyone originally intended.

It is worth defining that role explicitly.

An office focused mainly on investment oversight will be organized differently from one responsible for a much broader range of family affairs. The structure should reflect the work it has been asked to do.

A clear mandate makes decisions about the office much easier. It tells you where internal capability is needed and where outside support will be enough.

AUM is useful as a measure of scale. Workload comes from what the office has to handle.

Consider a family with a relatively simple billion-dollar investment portfolio. Now consider a family of the same wealth that also owns an operating business and supports several generations. The second family office will usually have much more work passing through it every day.

In practice, I find the level of activity more useful than AUM when thinking about how an office should be staffed.

UBS's 2026 Global Family Office Report found that 40% of family-office staff are non-investment professionals. That is a significant share of the workforce devoted to responsibilities outside investment management.

Operating costs also vary considerably. J.P. Morgan reports an average annual cost of $6.6 million for family offices overseeing more than $1 billion. Its 2026 survey covered 333 single family offices across 30 countries.

Those figures are useful benchmarks, but they do not tell a family how many people it should employ. The office has to be built around the work.

A family office director will rarely be the deepest expert in every subject the family encounters. A tax adviser should know more about tax. That is why the specialist has been hired.

The director has a different responsibility. They need to understand how the advice affects the family office and make sure somebody is carrying it forward.

This becomes particularly important when an office relies heavily on external providers. An issue can remain unresolved even when everyone involved is competent. Each party may reasonably assume that somebody else owns the next step.

The director has to see those gaps. They need enough visibility across the office to know where responsibility sits and when the family needs to become involved.

Specialist work can sit outside the family office. Responsibility for making the overall operation work still sits inside it.

Governance can sound more formal than it needs to be.

At its most practical level, people need to know when they have authority to act. They also need to know when a decision belongs with someone else.

The appropriate degree of formality will depend on the family. A larger or more complex family may benefit from an investment committee. A smaller office may need much less structure.

UBS found that 49% of family offices surveyed had a governance framework. Only 37% had a family-office strategy or operating manual, while 35% had a succession plan for the office itself.

The documents are useful when they reflect how the office actually works. If a policy is rarely consulted and does not affect decisions, its practical value is limited.

I generally favor a relatively small internal team with specialist support brought in when needed.

The amount of recurring work should carry a lot of weight in deciding whether a role belongs inside the office.

Property management is a simple example. A family with one property is unlikely to need a full-time property manager, however wealthy the family is. The position becomes much easier to justify if the family has ten properties that require active management.

Work that only arises occasionally can often be handled well by an external specialist. As the workload becomes more regular, an internal role can start to make economic and operational sense.

Outsourcing still requires management. UBS found that only 31% of surveyed family offices had a formal process for selecting and reviewing external service providers.

A small team works best when it retains a clear view of the work being done on the family's behalf.

Family members should understand the important financial decisions that affect them.

They do not need professional-level expertise. I think about this in much the same way as health. You do not need to be a doctor to understand the principles of good health and longevity.

That knowledge changes the quality of the decisions you make. It also makes conversations with specialists more useful.

The same applies to wealth. A family member who understands the basics can form their own view about a decision instead of relying entirely on somebody else's interpretation.

I also think education is too often framed as a next-generation issue. It is relevant to every family member.

The IMD and Family Business Network Global Family Office Report found that 56% of surveyed offices provide education. Professional development was offered by 52%.

A family office should help family members become more capable of making their own decisions over time.

A family can have genuinely bespoke needs without every recurring process being complicated.

Reporting is a good example. The final report might be tailored closely to the family, while much of the work required to produce it repeats every month or quarter.

Campden Wealth's 2025 Operational Excellence Report found that about one-third of family offices still perform more than half of their reporting manually. The same report estimates that around 40% have fully automated investment reporting.

A good reporting platform does not always remove the work surrounding the report. Staff can still spend a significant amount of time gathering information or resolving missing data before the platform can do its job.

I would look closely at the work that happens before and after the core system does its part. Follow the process from the point at which it enters the office and see where experienced people are repeatedly spending time keeping it moving.

Some of those steps will require judgment. Repetitive work often does not.

Technology or automation can help with that work, but the family should not have to change the way it wants to operate simply to accommodate a piece of software. The technology should fit around a process that already makes sense.

Small family offices often depend heavily on trusted individuals. That dependence becomes visible when one of those people leaves.

Another member of the team should be able to take over without reconstructing the role from an inbox. They should be able to understand the process from the records the office already keeps.

J.P. Morgan found that 86% of surveyed family offices did not have clear succession plans for key decision makers. Slightly more than half saw the absence of such a plan as a risk to the continuity and effectiveness of the office.

Succession planning is therefore relevant long before a generational transfer takes place. The departure of one important employee can create the same underlying problem on a smaller scale.

A family office will always depend on good people. The risk becomes more manageable when another person can understand how important work is done.

From the family's perspective, a well-run office should make life easier.

The family does not need to experience all of the complexity that sits behind the office. A family member should be able to raise an issue and know that the right person will deal with it.

Behind the scenes, the office needs enough internal capability to stay in control. Where outside expertise is more sensible, the internal team needs to remain close enough to the work to understand what is happening.

The same principle applies to the family members themselves. They should understand their affairs well enough to express their own priorities and make informed decisions.

Those priorities will change. So will the people working in the office. A good operating model can absorb those changes without having to be rebuilt each time.

A strong family office should allow individual family members to pursue the lives and priorities that matter to them, while helping the family advance its shared vision across generations.
