Many successful entrepreneurs and wealthy families assume that once their wealth reaches a certain level, the next step is to establish a family office.
In reality, many families do not need one.
A family office can be an excellent solution for some families, particularly those with substantial wealth, complex international affairs or multiple generations involved in managing family assets. For many others, however, the same objectives can often be achieved by combining existing advisers with specialist fiduciary services, without creating a dedicated organisation.
The key question is not whether you should have a family office. It is whether your family's needs justify one.
What is a family office?
A family office is an organisation established to help manage a family's financial, legal, administrative and governance affairs.
Depending on the family's circumstances, its responsibilities might include:
Coordinating professional advisers.
Overseeing investments.
Administering trusts and companies.
Cashflow and reporting.
Succession planning.
Philanthropy.
Family governance.
Education for future generations.
Lifestyle and administrative support.
Some family offices also manage household staff, travel arrangements and personal administration, while others focus purely on investment and governance.
Every family office looks slightly different because every family's needs are different.
What is a Single Family Office?
A Single Family Office (SFO) serves one family exclusively.
It is effectively a private organisation established by that family, employing its own professionals to manage wealth and coordinate advisers.
A Single Family Office may include:
Investment professionals.
Lawyers.
Accountants.
Tax specialists.
Governance advisers.
Administrative staff.
Single Family Offices are generally established by families with very substantial wealth and sufficiently complex affairs to justify the ongoing cost of maintaining a dedicated team.
What is a Multi-Family Office?
A Multi-Family Office (MFO) provides similar services, but for multiple unrelated families.
Rather than employing an in-house team, families share access to experienced professionals and established systems.
This approach often provides many of the benefits of a family office without the expense of building one from scratch.
The services offered vary considerably between providers. Some focus primarily on investment management, while others place greater emphasis on governance, administration or coordination.
Do you actually need a family office?
Not always.
Many internationally minded families already have a strong team of professional advisers, including:
Lawyers.
Tax advisers.
Accountants.
Investment managers.
Insurance advisers.
Trustees.
If those advisers work well together, establishing a formal family office may add unnecessary complexity rather than solving a genuine problem.
Instead, many families benefit from improving coordination between existing advisers and strengthening the underlying ownership and governance structures.
The right solution depends on the complexity of the family's affairs rather than the size of their wealth alone.
When might a family office make sense?
A dedicated family office may be appropriate where a family has:
Significant international assets.
Multiple operating businesses.
Several branches of the family involved in decision-making.
Complex investment portfolios.
Philanthropic activities.
A need for dedicated governance and administration.
Frequent transactions requiring ongoing coordination.
Even then, there is no universally accepted wealth threshold. Some families with substantial wealth prefer a lean external model, while others establish an internal office much earlier.
When a modular approach may be enough
Many families discover that they do not need a full family office at all.
Instead, they build a tailored support network using specialist advisers who each perform a clearly defined role.
This might include:
A trustee administering long-term wealth structures.
A tax adviser providing cross-border tax advice.
Lawyers handling legal matters.
Investment managers overseeing portfolios.
Accountants preparing financial reporting.
Property specialists managing real estate.
Corporate advisers supporting private businesses.
Rather than creating another organisation, the family focuses on ensuring these advisers communicate effectively and understand the family's long-term objectives.
For many families, this modular approach provides flexibility while avoiding the cost and complexity of maintaining a dedicated family office.
Where does a trustee fit?
A trustee is not a family office.
Their primary role is to administer trusts and other fiduciary structures in accordance with the governing documents and applicable law.
Depending on the family's arrangements, a trustee may be responsible for:
Administering trusts.
Holding companies or other long-term ownership structures.
Coordinating distributions.
Maintaining records.
Supporting family governance arrangements.
Working with legal and tax advisers across multiple jurisdictions.
Importantly, trustees generally work alongside a family's existing professional advisers rather than replacing them.
In many cases, they become the long-term point of continuity as lawyers, accountants and investment managers change over time.
Working together rather than replacing advisers
One common misconception is that appointing a trustee means replacing existing advisers.
In practice, the opposite is often true.
Well-functioning wealth structures typically rely on collaboration between specialists.
For example:
Lawyers advise on legal matters.
Tax advisers provide tax advice.
Investment managers manage investments.
Accountants prepare financial information.
Trustees administer the ownership structures and implement decisions within their responsibilities.
Each adviser contributes different expertise, while the family retains overall strategic direction.
International families often need coordination more than complexity
As families become more international, the number of advisers usually increases.
A family may have:
Businesses in one country.
Property in another.
Beneficiaries living elsewhere.
Investments managed internationally.
Tax obligations in multiple jurisdictions.
The challenge is often not finding more advisers, but ensuring the existing advisers work together effectively.
This is where experienced fiduciary administration can add value by helping coordinate information, maintain institutional knowledge and support the long-term operation of the family's structures across different jurisdictions.
Questions to ask before establishing a family office
Before creating a dedicated family office, consider:
What specific problem are we trying to solve?
Which functions do we actually need?
Could existing advisers work together more effectively?
Would strengthening our governance arrangements achieve the same objective?
Are our trusts and ownership structures already fit for purpose?
Who will coordinate advisers across jurisdictions?
How much administration would a dedicated family office create?
Sometimes the answer is that a family office is entirely appropriate. In other situations, a more focused combination of specialist services achieves the same outcome with greater flexibility.
Common questions
Is a family office only for billionaires?
No.
There is no universally accepted definition or wealth threshold. Family offices exist in many forms and vary considerably in size and complexity.
Can I have trusts without a family office?
Absolutely.
Many families use trusts without ever establishing a family office.
Does a trustee manage investments?
Not usually.
Investment management is often delegated to specialist investment managers, while the trustee remains responsible for overseeing the trust and ensuring decisions are consistent with the trust deed and applicable law.
Conclusion
A family office can be an effective solution for families with complex international affairs, but it is not the only model—and it is often not the most appropriate one.
Many families achieve excellent outcomes by combining experienced trustees, lawyers, tax advisers, accountants and investment managers into a coordinated advisory team. This modular approach allows each professional to focus on their area of expertise while supporting the family's long-term objectives.
Whether you establish a dedicated family office or continue working with existing advisers, the goal remains the same: creating a stable, well-governed framework that can support your family's wealth across generations and jurisdictions.
