One Child Takes Over, the Others Don't: Structuring Fairness Without Breaking the Family

Here are the ten points that, in the mandates I run, separate a handover to one child that enriches the one who stays and shortchanges the ones who leave, from a succession the family gets through without a lasting rift.

The ten points to settle before fixing a number

1. Separate who runs the company from who inherits. These are two different decisions that almost always get tangled together in family conversations. Who takes over leadership is a question of skill and appetite for carrying the business, how its value is split is a question of inheritance law, and blurring the two turns the first decision, a legitimate one, into a sense of unfairness about the second.

2. Have the company valued by an independent expert. A figure the parent picks to keep the peace, or one the successor child proposes, rarely survives a later disagreement. A valuation held by a third party, a fiduciary or a business appraiser, gives every child a number they can challenge on method, not on the motives of whoever produced it.

3. Choose the transfer mechanism before arguing over the amount. A gift with an equalization payment, an internal sale at a reduced price, or a mix of both: the structure you pick changes the tax consequences and the payment timeline, and settling it first avoids renegotiating the whole arrangement every time a figure moves.

4. Base the equalization payment on the real value, not a number chosen out of affection. Imagine three siblings where one takes over a company valued at four million francs: setting the payout to the other two at eight hundred thousand francs because it felt like a round, manageable number leaves each of them with a fraction of what inheritance law actually recognizes as theirs. The calculation starts from the value fixed in point two, not from a figure that feels reassuring in the moment.

5. Spread the payment if the company's cash doesn't support it. A successor rarely able to pay the equalization amount in cash can repay it over five to ten years, at an interest rate that reflects the risk their siblings are carrying as creditors. Financing the takeover through a third party, a bank or an outside investor, is worth considering when spreading the payment alone would strain the company's ability to invest.

6. Draw on assets outside the company to balance the scales. A life insurance policy the parent takes out for the non-successor children, a property held separately, or a securities portfolio can settle part of the fairness gap without the company itself funding its own succession through distributions that weaken it.

7. Sign an inheritance agreement while the parent is still alive to set the rules. Since the revision of Swiss inheritance law that took effect in 2023, the statutory share reserved for descendants has been reduced and the freely disposable portion widened, giving more room to favor a successor child within the rules. An agreement signed by everyone, with a partial waiver of the reserved share where needed, locks in that room instead of leaving it open to challenge after death.

8. Plan for the case where the successor sells the company soon after. An equalization payment that looks fair today can feel generous to some and too small to others if the successor child sells the business three years later at a noticeably higher price. A time-limited clause sharing the upside on a quick resale protects the siblings without stripping the successor of the reward for the work they put in once that window has passed.

9. Hand the discussions to a neutral third party. A parent who chairs the negotiation personally is both judge and party, often seen as already siding with the child who is taking over. A notary, a lawyer specializing in inheritance law, or a family advisor who runs the conversation gives every child room to voice disagreement without it turning into open conflict with the parent.

10. Put the agreement in writing while the parent can still settle disputes. An arrangement left verbal, or sketched out in a family email, loses all force the day the parent is no longer able to confirm what they intended. The inheritance agreement, the internal sale contract and, where relevant, the company's revised articles need to be signed while the person who arbitrated can still answer questions.

None of these ten points removes the tension built into this kind of handover, one child receives the working business and the others receive its cash counterpart, and the two are never worth the same thing emotionally. What they do is anchor that tension in figures and rules every sibling had a chance to discuss, rather than in a sense that the arrangement was settled behind the family's back. In the successions I've seen go through without lasting family damage, the difference rarely comes down to the final amount, it comes down to how that amount was built.
