In global families, the most dangerous moment may not be death. It may be the years before it.
When a founder dies, the family usually knows that a legal process will begin. Wills are reviewed, executors are appointed, succession rules are applied and advisers step in. The situation may be complex, but at least the legal event is clear.
Loss of capacity is different.
A founder may still be alive, still legally the shareholder, still named on bank accounts, still recognised as the decision-maker by employees, advisers and family members. But if age, illness, cognitive decline or an accident affects their ability to make decisions, a difficult question emerges: who actually controls the family wealth?
For families with assets in several countries, the answer is rarely simple. The founder may own real estate in Spain, hold financial assets in Switzerland, control a company in the United States, benefit from a trust, own art through a structure, and have children living in different jurisdictions. A local power of attorney may work in one country but not in another. A bank may refuse instructions. A board may become divided. A spouse, children from a first marriage and professional managers may all claim to be protecting the founder’s interests.
This is where private wealth planning often reveals its weakest point. Families tend to prepare for tax, investment and inheritance. They are less prepared for the grey zone in which the founder is alive but no longer fully able to lead.
The legal issues can be immediate. Who can sign for the holding company? Who can approve a sale? Who can access liquidity to pay taxes, household staff or medical expenses? Who can speak to banks, trustees, investment managers or lawyers? Who decides whether a family property should be sold, kept or transferred? Who protects the founder from undue influence?
These questions become even more sensitive when the founder has been the centre of the family system. In many entrepreneurial families, authority was never fully institutionalised. The founder knew the assets, the advisers, the informal promises and the real balance of power. Once that person loses capacity, the absence of clear governance can turn uncertainty into conflict.
From a legal perspective, capacity planning should sit at the heart of any serious wealth structure. Powers of attorney, corporate signing authorities, medical directives, trust provisions, shareholder agreements, family protocols and succession documents should be reviewed together, not in isolation. It is not enough to have a will. A will speaks after death. The real problem may arise before then.
Jurisdiction also matters. A document valid in one country may not be effective elsewhere. Some legal systems require court involvement before a representative can act. Others may recognise enduring powers or protective mandates more easily. The location of the assets, the residence of the founder, the nationality of family members and the governing law of companies or trusts can all affect who has authority at the critical moment.
For international families, this is not only a legal risk. It is a reputational and financial risk. A disputed capacity situation can freeze decision-making, delay transactions, trigger litigation, expose family divisions and weaken the value of operating businesses. It can also create vulnerability around the founder, especially where new relationships, dependent relatives, advisers or employees begin to exercise influence.
The most sophisticated families do not wait for this moment. They design a control map before capacity becomes uncertain. They identify who can act, when they can act, under what safeguards and with what reporting obligations. They create mechanisms that protect the founder’s dignity while preserving continuity for the family and the business.
This does not mean removing control too early. It means avoiding a vacuum. A well-designed structure can allow the founder to remain involved for as long as possible, while ensuring that, if capacity declines, authority passes in an orderly and legally recognised way.
The uncomfortable truth is that wealth does not protect a family from human fragility. It often amplifies the consequences. The larger and more international the estate, the more dangerous silence becomes.
For global families, the question is not only who inherits when the founder dies. It is who can act when the founder can no longer decide.
That question should be answered before the family needs the answer.
