In 1955, ten cousins meet in Roubaix – a northern French textile town – and sign one rule: each of us is a shareholder in all of the others, and none of us may sell out alone. Tous dans Tout. Everyone in Everything.
Seventy years later that family numbers more than 1,650 people, 994 of them shareholders, holding 150 companies that employ 615,000 across 62 countries.[1] You have shopped in their stores (Auchan, Decathlon, Leroy Merlin) and probably never heard their name.
This rule had nothing to do with money or numbers in a strict sense.
The five capitals of family wealth are human, intellectual, social, legacy and financial – and financial comes last for a reason, because its job is to serve the other four.
Your family holds all five today. The question is not whether you have them. It is whether anyone in your current structure is accountable for more than one of them.
I guess almost nobody is.
Five capitals of family wealth: the Unwritten Family Balance Sheet
Picture © Rajiv Perera / Unsplash
Only one capital is audited, custodied, benchmarked, insured and reported on a quarterly basis. It’s usually the financial capital. The other four are real and consequential but not documented anywhere.
I have come to call this the Unwritten Family Balance Sheet.
It's not because the family denies that the other four capitals exist – principals often name them instantly when asked. It's just that nobody ever gave them a ledger.
There is no report on whether your second son is capable. There is no quarterly statement on whether the leaders in your two branches are still communicating. There is no auditor who signs off on whether anyone under forty knows what the money is for.
So those four capitals get managed the way anything unmeasured gets managed: at funerals, at weddings, and in the six weeks after a diagnosis.
The Roubaix family is instructive precisely because it is so boring. They did not out-invest anyone. They opened five ledgers and kept all five – the five capitals of family wealth.
Five capitals of family wealth – what it is and when it fails
Five Capitals of Family Wealth | What it is | What it looks like when it fails |
|---|---|---|
Human | The individuals – their health, capability, character and agency. | Heirs who are competent at nothing because they were never required to. |
Intellectual | What the family knows, and whether that knowledge transfers to the next-gen. | Every generation re-learns the same lessons at full cost. |
Social | Trust inside the family; standing (reputation) and network outside it. | Branches that communicate through lawyers. |
Legacy | The agreed purpose, and the governance that carries it past you. | A structure nobody remembers agreeing to and nobody actively defends. |
Financial | The classical balance sheet. | The visible symptom of the four failures above. |
What is human capital in a family, and why is it the first capital?
Human capital is the people themselves – their health, capability, character, and capacity to act on their own behalf. It is first because every other capital is held by a person. A family with a pristine balance sheet and one incapacitated principal has a liquidity problem it has not discovered yet.
The failure mode here is not the one you have been sold.
Scott Peppet runs Chai Trust,[2] the private trust company behind the Sam Zell family office. When asked what can go wrong when heirs never integrate their inherited wealth, he initially mentioned the stereotype of the eighteen-year-old with a gifted Ferrari, but then set it aside.
What he sees far more often is the opposite: heirs who are frozen. Blocked. They do not overspend. They do nothing. The capital pays their bills and never becomes truly theirs, so they never start the business, never fund the cause, never deploy any of it.
His phrase for what is lost is exact: financial capital is concentrated potential, and potential never released is not preserved. It is forfeited.
I have noticed this in situations where parents were confident that their money was safe. It was. However, the person standing next to it was not, due to the denial of their family's generational legacy, to name just one reason.

What is intellectual capital in a family, and how does it get lost?
Intellectual capital is what the family knows and can transfer – judgment, technical skill, hard-won experience, and the systems that move all of it to the next generation. It is the capital most often destroyed by accident (or ignorance), because families confuse having knowledge with transmitting it.
You built a company. You acquired judgments about risk, counterparties, cycles and people that took twenty-five years and several expensive errors to assemble. Almost none of it is written down. It lives in your reflexes and intuitions.
Build no mechanism to move it and it leaves the family when you do – and your children pay the full price to learn it again from strangers.
The Roubaix family made this structural, rather than hopeful. Their charter dates to 1968.[1] Their family incubator backs more than 40 family entrepreneurs across 26 companies, and each year more than 50 young family members take a first professional role inside the ecosystem.
That is not sentiment. It is an apprenticeship system with a budget, and it is why the sixth generation can read a P&L.
What is social capital, and why does it decide whether a family survives?
Social capital has two faces. Inside the family it is trust – the ability of people who did not choose each other to make consequential decisions together. Outside it, it is standing, reputation and network: what happens when your name is spoken in a room you are not in.
The internal face is where the money actually goes.
Roy Williams and Vic Preisser tracked more than 3,200 families through actual wealth transitions over twenty years.[3] Roughly 70% of transfers fail – assets dissipate or the family fractures – by the end of the second generation.
Their causation split is the part that should stop you: 60% traced to a breakdown of trust and communication inside the family, 25% to heirs who had not been prepared, 10% to families with no agreed purpose for the wealth. Everything else combined – tax, legal and document error – accounted for the remaining 5%.
Ninety-five per cent of the risk sits in the four capitals nobody keeps books on. Ninety-five per cent of the preparation goes into the fifth.
Notice what the 1955 Mulliez families' rule actually did. "None of us may sell out alone" is not a tax provision. It is a trust mechanism: it removes the exit that lets a resentful branch convert a disagreement into a liquidation event.
Then they made participation the norm rather than the exception – more than 500 family members, aged 16 to 99, engage with the businesses each year.[1]
What is legacy capital, and how is it different from philanthropy?
Legacy capital is the agreed purpose of the wealth, and the governance that carries that purpose past the person who created it. It is not philanthropy, though philanthropy often expresses it in the world. It is the only capital defined by an obligation to people not yet in the room.
A note on the naming, because I have changed a word deliberately. The capitals' framework originates with James E. Hughes Jr., whose Family Wealth: Keeping It in the Family (1997)[4, 4a] put human, intellectual and financial capital in its subtitle and displaced money from the centre of the conversation. Hughes and the advisers around him later extended it to five, with spiritual capital as the fifth.
I use legacy instead, for practical rather than cosmetic reasons. ""Spiritual" is a word of private conscience and is an essential part of being human, and therefore part of every individual's and family's system.
It may just not survive in a family assembly with four branches, three generations and three religions in the room – someone always hears it as pressure to sign up to a certain belief (which it doesen't). How it is seen (and felt) depends on the consciousness level of all those involved.
"Legacy" names the same generational obligation in a form a family can govern more easily: write it down, disagree about it, vote on it, amend it in ten years, hand it to a successor. But deal with it in a conscious way. A capital you cannot put to a dicussion or vote is not a capital you are managing.
The Roubaix family votes on theirs. Every ten years the whole family reconvenes to rewrite a common vision for the next twenty; the current one runs to 2035. Their businesses are measured on four criteria, only one of which is profit.
The plain version: if you were removed from the picture this year, could anyone in your family state in five sentences what the wealth is for? If not, that capital is not underperforming. It just does not exist yet.
Why do I list financial capital last of the five capitals of family wealth?
Because it is the visible symptom of failures (or successes) that occur upstream of it.
Cornelius Vanderbilt died in January 1877 holding roughly one hundred million dollars, among the largest personal fortunes in American history.[5] In 1973, one hundred and twenty of his descendants gathered at the university that carries his name.
The family historian who chronicled it, Arthur T. Vanderbilt II, recorded in Fortune's Children what everyone in that room already knew: not one Vanderbilt present at that time was a millionaire.
Here is the part that should bother you: Nobody in that story made a catastrophic investment. No fraud, no market event, no single ruinous decision.
The financial capital stayed intact for decades while the other four were spent – on competitive mansion-building, on branches that stopped functioning as a family, on a generation raised to be conspicuous rather than capable, and in the absence of any agreed answer to what the fortune was meant for.
Two families, same century, opposite outcomes. Neither turned on investment skill.
Financial capital is not less important than the other four. It is downstream of them. Deployed well it is the powerful fuel for all four: it pays for the education, the meetings, the incubator, the governance, the foundation.
Deployed into a families' single and only ledger, it accelerates whatever is already happening. If the other four are unmanaged, that means it accelerates the dissolution.
Five capitals of family wealth: why do most families still manage only one?
Because only one has an industry attached to it. The other four family capitals have no obvious owner, no reporting cadence, and nobody who gets fired when they decline.
The industry's own data says so plainly. The UBS Global Family Office Report 2026, published in May 2026,[6] surveyed 307 family offices across more than 30 markets with an average family net worth of USD 2.7 billion – families with every resource required to do this properly.
Sixty-eight per cent had formal financial performance measurement. Sixty per cent ran an investment committee. But fewer than half had a governance framework with board-level oversight, only 35% had a defined succession plan for the family office itself, and only 27% had a structured process to educate and prepare their heirs.
Although non-representative it points in a clear direction: two-thirds measure the financial capital formally. Roughly a quarter do anything structured about the human one.
The advisory profession has already conceded the point, if you know where to look. The UHNW Institute's Ten Domains of Family Wealth,[7] the field's competency map, devotes four of its ten domains to money, law and risk.
Five sit under a heading the Institute calls Cultivation of Family Capital: governance and decision-making, leadership and transition, learning and the rising generation, family dynamics, and health and well-being. The tenth is the advisory relationship itself.
Half the map is off your (financial) balance sheet. Almost all of your spending is on the other half.
How do you open a ledger on the other four capitals?
You do not need a new structure to start. You need four reporting lines where you currently have one in order to deal with all five capitals of family wealth.
- Write the purpose before the structure. One page: what this capital is for, over what horizon, and what would count as having failed. That is legacy capital, and it takes an afternoon (ideally). See also: The Biggest Mistakes Wealth Creators Make After Selling Their Business .
- Put all five capitals on the family meeting agenda by name. Not "any other business" – five standing items, financial last, every time. The agenda itself is the ledger.
- Name an owner for each. Human capital without an accountable owner is a wish. A family member, a council, or an external adviser – but somebody who reports on it.
- Build one transfer mechanism for intellectual capital this year. An apprenticeship, a documented investment thesis, a rule that next-gen sits in on the investment committee before they vote in it. One is enough to start.
- Test social capital with a decision, not a survey. Give the family something real and small to decide together and watch how the decision actually gets made. That is your baseline.
The families I have watched navigate three generations well were not the ones with the best financial managers or advisers. They were the ones who understood early that they were running five balance sheets, and refused to keep books on only one.
Ten cousins in Roubaix worked that out in 1955, with a rule that had nothing to do with money and everything to do with who would still be in the room in seventy years. A well-considered (and successful) decision to focus on all five capitals of wealth.
Steward your wealth. Don't just hold it.
Frequently Asked Questions (FAQ)
The five capitals of family wealth are human capital (the individuals and their health, capability and character), intellectual capital (what the family knows and can transfer), social capital (trust inside the family and standing outside it), legacy capital (the agreed purpose of the wealth and the governance carrying it forward), and financial capital (the balance sheet). The framework originates with James E. Hughes Jr.,[4, 4a] and holds that financial capital exists to serve the other four rather than the reverse.
Because it is downstream of the other four and is usually the visible symptom of failures that occurred elsewhere. Research by Roy Williams and Vic Preisser[3] across more than 3,200 families found that 60% of failed wealth transitions traced to breakdowns of trust and communication, 25% to unprepared heirs, and 10% to the absence of an agreed purpose – with tax, legal and document error accounting for just 5% combined.
Legacy capital is the family's agreed purpose for its wealth together with the governance that carries that purpose beyond the generation that created it. Philanthropy is one expression of it, not a substitute for defining legacy capital. A family can give substantial sums away and still hold no legacy capital, if nobody has developed and written down what the wealth is for or built a mechanism to keep that answer alive after the founder.
Very few, by their own account. The UBS Global Family Office Report 2026,[6] covering 307 family offices with an average family net worth of USD 2.7 billion, found that 68% had formal financial performance measurement while only 27% had a structured process to educate and prepare their heirs, and only 35% had a defined succession plan for the family office itself.
Both formulations circulate. James E. Hughes Jr.'s 1997 book[4] named human, intellectual and financial capital; social capital was added subsequently, and a fifth – usually described as spiritual capital – was added in later work. NewGrowth.Capital uses legacy capital as the fifth, on the grounds that a family can write down, debate, amend and vote on a legacy statement in a way that is harder to do with a term drawn from private belief.
With the jointly developed purpose statement and the meeting agenda, in that order. Writing one page on what the capital is for establishes legacy capital, and putting all five capitals on the family meeting agenda as named standing items – financial last – creates the reporting cadence the other four have never had. Neither step requires a new legal structure.
