The Illiquid Inheritance
The one event a family cannot reschedule is also the one that tests it hardest. A succession arrives with its own demands, inheritance tax, equalisation between heirs, the upkeep of everything the family has built, and it arrives at the moment the person who understood the whole picture is no longer there to manage it. When the estate is illiquid and the authority to run it was never transferred, a fortune built over a lifetime can be broken up to settle a bill it should have seen coming. This is the third and final essay on liquidity.
The first two essays in this series were about a family in motion, deciding what it can reach and arranging the means to reach it. This one is about the moment the family is not in motion, when it changes hands. A succession is the one demand on a balance sheet that cannot be deferred, negotiated or timed. It comes when it comes. And it brings with it the largest and least forgiving liquidity event most families will ever face, at the precise moment they are least equipped to meet it, because the person who understood how everything fit together is the person who is gone.
The estate that cannot be divided
The illiquid inheritance is the estate that is worth a great deal on paper and cannot be turned into cash, or divided cleanly, when it must be. Most of it is the operating company, the property and the private holdings the earlier essays described, only now they carry a further problem: they have to pass. An operating business left to three children is not three portions of anything. It is one asset that cannot be split without destroying it, given to heirs who may not agree, may not be involved, and may not want the same things. The estate owes inheritance tax it may have no cash to pay. It owes an equal share to the children who did not receive the business, in money the estate does not hold. And it owes the continued upkeep of everything, the company, the properties, the obligations, through a period when no one is clearly in charge. None of these demands waits, and none of them can be met by an asset that will take years to sell.
Two problems arriving together
What makes a succession different from any other liquidity event is that two problems land at the same time. One will be familiar from these essays, that the wealth is illiquid while the demands come in cash. The other is worse because it is new. The person who might have solved the first is no longer there. In most families the founder was the liquidity plan, the credit relationship, the institutional memory and the last word all at once, and when that person goes the family does not simply inherit assets. It inherits every unsolved problem together, without the mind that held the answers. The research is blunt about it. In large studies of family offices, most have no clear succession plan for the people who actually make the decisions, however sophisticated the governance of the money itself. Families institutionalise the running of the money long before they institutionalise the right to run it, and that gap is never wider than at a succession.
A plan is not preparedness
Most families are not unaware of this. They have a plan. There is a will, a structure, named heirs, perhaps a trust. What they do not have, more often than not, is preparedness, which is a different thing entirely. A plan says who gets what. Preparedness asks whether, on the day, the cash is there to pay the tax without selling the business, whether the heir who takes the company is ready to run it, whether the others can be made whole without a forced sale, and whether anyone but the founder can actually sign. The studies that report most families holding a succession plan also report that only a minority describe that plan as thorough, and fewer still are confident the next generation is ready. The distance between having named a successor and having a successor who is prepared is exactly the distance a family office exists to close.
What has to be arranged before
Everything that makes a succession survivable has to be built before it happens, because none of it can be built after. The liquidity to meet the tax and the equalisation has to be arranged while the balance sheet is strong and the family can plan, not found in a hurry once the estate is frozen and the clock is running. The assets that will pass have to be made transferable in advance, structured so the business can move to the next owner without a fire sale and the illiquid holdings can be divided or bought out cleanly. And the authority to run it all has to be transferred while the founder is still there to transfer it, so that when the moment comes there is someone prepared, and trusted, to decide. This is coordination and preparation, not legal or tax advice. The structuring, the tax and the estate are the work of the family's lawyers and advisers; the family office's task is to see the whole picture years ahead, to arrange the liquidity and the readiness alongside them, and to make sure that when the one event that cannot be rescheduled arrives, the family is prepared for it rather than surprised by it.
A succession is where everything these essays have described comes due at once. The liquidity that was never mapped, the credit that was never arranged, the business that was never prepared to pass, the successor who was never ready to take it, all of it arrives in the same season, and the family faces it without the one person who might have known what to do. The estates that come through the handover intact are rarely the largest, or the ones with the most elaborate documents. They belong to the families that did the slow, unglamorous work early, that treated liquidity and continuity as things to be built over years rather than found in weeks, so that when the day came there was little left to solve in a hurry, because it had already been solved with time.
