Do You Need a Family Office? 6 Tests Before a Business Family Builds One

In 1882, John D. Rockefeller hired a small team of professionals to run his personal affairs: his investments, his properties, his philanthropy and the growing list of people who depended on him. It is widely cited as the prototype of the American single-family office. More than 140 years later, that office still exists as Rockefeller Capital Management, and it now serves families who are not named Rockefeller.

The idea has never been more popular. Deloitte Private estimates there are about 8,030 single-family offices in the world, up from 6,130 in 2019, and projects more than 10,720 by 2030. Every successful founder eventually hears the pitch: you have outgrown your bank, you need your own office.

Sometimes that is true. Often it is not. A family office is not a trophy for having made money; it is an operating company whose only customer is your family, and it has to earn its costs like any other business. In a family that has been building companies since 1890, I have learned to treat this decision with the same discipline as an acquisition. These are the six tests I would apply before any business family builds one.

What a family office actually does

A single-family office is a private company owned by one family that manages its wealth and affairs. The scope varies, but it usually covers:

• Investment management: asset allocation, manager selection, direct deals and reporting.
• Administration: accounting, tax filings, legal entities, insurance and bill payment.
• Family services: estate planning, governance, education of the next generation and philanthropy.

A multi-family office offers the same services to several families at once, sharing the cost. A "virtual" family office coordinates outside advisors without building a full team. Those alternatives matter, because the right answer for many families is one of them.

Test 1: The complexity test, not the net worth test

Most guides start with a number. Charles Schwab says a dedicated family office generally only makes sense above $100 million in net worth, and Kiplinger suggests most families need more than $250 million.

Those thresholds are useful, but they miss the real trigger. The question is not how much you have; it is how many moving parts you are coordinating and how often they collide. A family with $60 million in one listed portfolio needs a good private bank. A family with $60 million spread across three operating companies, two countries, six holding entities and four sets of advisors who never talk to each other may need something more.

Count the parts:

• Legal entities and trusts you own or control.
• Tax jurisdictions you file in.
• Outside advisors (banks, lawyers, accountants, insurers) you pay each year.
• Family members who depend on shared assets or decisions.

If nobody can draw that map on one page, the problem is coordination, and coordination is what a family office sells.

Test 2: The cost test, measured in basis points

Family offices are expensive, and the costs are mostly fixed. Industry surveys by Campden Wealth and UBS put the average pure operating cost at around 40 basis points of assets under management, with typical annual budgets of $2 to $3 million once you add a chief investment officer, a controller, tax and legal support, systems and rent. Citi's 2025 Global Family Office Report found that 36% of offices spend less than 50 basis points a year.

Now run the math on a smaller family. A $2.5 million budget on $100 million of assets is 2.5% a year, before a single investment return. If the office costs more than the value it adds in returns, tax savings and avoided mistakes, it is not a family office; it is an expensive hobby.

Write down, before you hire anyone, what the office must deliver each year to justify its budget. Then measure it, the same way I would measure any business in the group.

Test 3: The separation test

The most common way founders build a family office is by accident. The company CFO starts paying the family's bills. The operating company's accountant files the personal returns. A house gets bought through the business because it was easier.

This feels efficient. It is dangerous. The family's wealth and the operating company's balance sheet must be separated, legally and operationally, or a crisis in one becomes a crisis in both. A bank covenant, a lawsuit or a bad year in the business should not be able to reach the family's liquid savings, and family spending should never show up in the company's accounts.

Separation means different entities, different bank accounts, different staff where possible, and documented terms for anything that crosses the line, such as a property the company rents from the family. I wrote about the tools that keep those boundaries clear in the family constitution, and they apply just as much to the office as to the business.

Test 4: The governance test

In March 2021, Archegos Capital Management collapsed in a matter of days. It was the family office of Bill Hwang, and because family offices face lighter disclosure rules than funds that manage outside money, almost nobody could see how much leverage it had built. When the positions unwound, the banks that financed them lost more than $10 billion, with Credit Suisse alone losing about $5.5 billion. Hwang was later convicted of fraud.

Archegos is an extreme case, but the lesson is ordinary. Privacy is one of the main reasons families set up an office, and privacy without governance removes every outside check on bad decisions.

Before the office invests a single euro, it needs:

• A written investment policy: target allocation, liquidity needs, leverage limits and forbidden assets.
• An investment committee that includes at least one experienced outsider with no stake in the outcome.
• Independent reporting so the family sees the same numbers the office sees.
• A clear rule for who can approve what, including limits for family members themselves.

Test 5: The people test

A family office is a small company that lives or dies on two or three people. The most important hire is usually the head of the office or the chief investment officer, and that person will know more about the family's finances than most family members do.

Hire for judgment and integrity first, investment brilliance second; a family office needs someone who will say no to the family, not someone who will chase returns to impress it. Pay matters too. Tie variable pay to long-term results and to the budget you set in test 2, not to activity or short-term gains.

Plan for the day that person leaves. Document the structure, the accounts, the passwords held in proper custody and the reasoning behind each major investment. A family office that depends on one person's memory has recreated the key-person risk it was meant to reduce.

Test 6: The purpose test

Ask each adult member of the family one question: what should this office exist to do in 30 years?

If the answers are only about returns, a good private bank or a multi-family office can probably deliver them at lower cost. The families that get the most from a single-family office use it to hold the family together, not just the money: educating the next generation, running shared decisions and philanthropy, and preparing heirs to be owners rather than spenders.

That purpose also shapes the other big question every business family faces: how much of the profit goes back into the companies and how much comes out to the owners. I covered that trade-off in reinvestment versus dividend discipline. The office should implement that policy, not invent it.

If your family cannot agree on a purpose yet, do not build the office yet. Start with a multi-family office or a coordinated set of advisors, fix the separation between business and family, and revisit the decision in two or three years.

Key Takeaways

• A family office is a business whose customer is your family, and it must earn its costs every year.
• Complexity, not net worth alone, is the real trigger: count entities, jurisdictions, advisors and dependents.
• Budget in basis points; at $100 million, a full office can cost 2% to 3% a year before any return.
• Separate the family's wealth from the operating company legally and operationally, before a crisis forces you to.
• Privacy without governance is how family offices fail: write an investment policy and bring in an outsider.
• Hire someone who will tell the family no, and document everything so the office survives their departure.
• If the family cannot agree on a 30-year purpose, choose a multi-family office for now.

Frequently Asked Questions

At what net worth should you have a family office?

Most advisors put the threshold for a dedicated single-family office at around $100 million, and many say $250 million or more. Below that, the fixed costs usually outweigh the benefits, and a multi-family office or a coordinated group of advisors does the job at a fraction of the price. Complexity can justify an office earlier; simplicity can make it unnecessary even at higher levels.

What is the minimum for a family office?

There is no legal minimum, but there is an economic one. A fully staffed office typically costs $2 to $3 million a year, so the assets under management have to be large enough that this cost stays well under 1% a year. Lighter models, such as a virtual family office with one coordinator and outsourced specialists, can work for smaller fortunes.

What are the disadvantages of a family office?

The main disadvantages are high fixed costs, dependence on a few key people, the risk of mixing family and business money, and weak oversight. Because family offices face lighter disclosure than funds, bad decisions can stay hidden for a long time, as the Archegos collapse showed in 2021. Good governance and outside members on the investment committee reduce these risks.

What are the tax advantages of having a family office?

A family office can coordinate tax planning across entities, countries and generations, which often saves more than any single advisor can. The specific advantages depend entirely on the jurisdiction and the structure used, and rules change frequently, so every structure should be reviewed by qualified tax counsel in each country involved. Tax savings should be a benefit of the office, never its only reason to exist.

Can you run your own family office?

Yes, and many families start that way, with a family member coordinating advisors and investments. It works while the wealth is simple and the family member has both the skill and the time. Once the complexity grows or several generations are involved, relying on one relative creates key-person risk and family tension, and professional staff becomes worth the cost.

One Thing to Do This Week

Draw your family's financial map on a single page: every entity, account, advisor, jurisdiction and person who depends on shared assets. If the page is simple, you do not need a family office. If you cannot finish it, that is the strongest sign you need one, or at least someone whose job is to own that map.
