- · As of 1 January 2023, Swiss inheritance law no longer grants parents any compulsory portion of a founder's estate, removing a long-standing structural constraint on succession planning.
- · Young, unmarried founders without children now enjoy near-total testamentary freedom, making external M&A transfers, management buyouts, and non-family successions materially easier to execute.
- · The disposable portion of an estate has expanded substantially under the reform, though a second legislative stage aimed at a dedicated business succession statute failed in 2024.
- · Advisors are urged to review existing wills and inheritance contracts drafted before January 2023, as many instruments no longer reflect the expanded freedoms now available.
Swiss inheritance law is not a subject that tends to dominate founder conversations over lunch. Liquidity, valuation multiples, and the perennial question of whether to bring in a strategic buyer or hand the business to management tend to occupy that space instead. Yet a reform that entered into force on 1 January 2023 has quietly rearranged the succession landscape for one specific cohort of founders in a way that deserves careful attention: those who are young, unmarried, and without children.
The change in question is the complete abolition of parental compulsory portions under Swiss private inheritance law. Under the previous regime, parents held an entrenched legal claim to at least half of their statutory share of a child's estate, regardless of what that child had specified in a will or inheritance contract. For a founder whose most valuable asset was a privately held operating company, that parental entitlement was not a theoretical inconvenience. It was a structural constraint that required active legal engineering to work around.
That constraint no longer exists.
To appreciate the significance of the change, it is worth briefly reconstructing what the pre-2023 framework demanded. Swiss inheritance law has long distinguished between the disposable portion of an estate, which a testator may direct freely, and the compulsory portion, which is reserved by law for certain close relatives regardless of testamentary intent.
Before 2023, the compulsory portions were as follows: descendants were entitled to three-quarters of their statutory share, and parents were entitled to one-half of their statutory share. Spouses and registered partners retained their own protected fractions. The cumulative effect was that a testator's disposable freedom was considerably narrowed, particularly when parents were alive and there were no descendants.
For a founder in their thirties, unmarried and without children, this meant that parents could assert a legally enforceable claim against the estate. In the context of a business succession, that claim could translate into cash demands against a successor who had acquired the company, creating liquidity pressure at precisely the moment when the business most needed capital stability.
The 2023 revision introduced two structural modifications. First, parental compulsory portions were abolished entirely. Parents no longer hold any protected fraction of a child's estate under Swiss law, regardless of circumstance. Second, descendants' compulsory portions were reduced from three-quarters to one-half of their statutory share, expanding the disposable portion available to testators with children as well.
For the specific cohort this post concerns, unmarried founders without descendants, the practical implication is close to absolute testamentary freedom. With no surviving spouse, no children, and no parental compulsory claim, such a founder may now direct the entirety of their estate as they see fit. A business can be transferred to a long-standing managing director, an external acquirer, a strategic partner, or a trusted employee, without the legal architecture needing to account for mandatory parental entitlements.
As one observer in the founder community captured the underlying disposition, if not the legal specifics:
i'm 23, from Switzerland, finishing a degree that's already been outdated by ai. so i teach myself at night and build my own products with what actually works. all of it for one reason: the freedom to answer to no one.§ @projetlockin
The sentiment is recognisable. The legal reform has, in structural terms, extended that same logic into the domain of succession: the freedom to direct one's estate, and one's business, without mandatory interference from parental claims.
The reduction in succession friction is most visible when mapped against the practical mechanics of business transfers. Prior to the reform, a founder without children who wished to transfer a company to an external party faced the risk that parental heirs would assert claims against the estate, potentially destabilising the succession arrangement. This required either anticipatory planning, such as structuring the business transfer during the founder's lifetime through sale or donation, or constructing trust-like mechanisms to ring-fence assets.
Under the new framework, the range of succession instruments available to such a founder has expanded. External M&A transactions, management buyouts by key employees, and transfers to non-family strategic successors are all structurally cleaner to document and execute. The successor's position is more secure, and the legal due diligence required of advisors on the buyer's side is correspondingly less complex.
The reform also introduces, or at least contemplates, payment deferral provisions of up to ten years for compensation owed to non-succeeding heirs, a mechanism designed to ease liquidity pressure in business transitions. This is a meaningful practical tool, since the most common point of friction in business succession is not the legal transfer itself but the cash demands that arise when some heirs receive the company and others must be compensated in kind.
The observation from the advisory community is well-grounded:
Every founder begins by chasing opportunities. Every enduring founder is eventually defined by decisions. Hiring the right people. Letting go of control. Choosing investors. Building partnerships. Planning succession. Knowing when to exit. Never losing sight of purpose.§ @LawBatra
Succession planning, in other words, is not a terminal event but one decision in a sequence. The 2023 reform makes one part of that sequence less encumbered by legal defaults that may not reflect a founder's actual intentions.
It would be an incomplete account to leave out what did not happen. The 2023 compulsory portion changes were framed, at the time of their passage, as the first stage of a broader reform. The second stage was intended to introduce a dedicated statutory framework for business succession, addressing issues such as valuation methodologies, heir compensation mechanisms, and procedural protections for operating companies.
That second stage failed in parliament in 2024. The implications are worth noting plainly: the 2023 changes remain the primary legal mechanism available to founders and their advisors for simplifying entrepreneurial succession under Swiss private law. There is no supplementary statute providing additional clarity or protection. The tools available are those that now exist, and the responsibility for deploying them correctly rests with qualified legal and fiduciary counsel.
One practical consequence of the reform that is easy to overlook in the analysis of its substantive changes is its effect on documents drafted before 2023. Wills, inheritance contracts, and partnership agreements that were structured under the old compulsory portion regime may no longer reflect either the legal reality or the founder's intentions. An inheritance contract that allocated a specific fraction of the estate to account for parental entitlements, for example, may now over-allocate in a way that unnecessarily constrains testamentary freedom.
Fiduciaries and wealth managers advising founders in this cohort should treat document review as a routine step following the reform, not an exceptional one. The legal landscape has changed; the documents should reflect it.
This is a market observation, not legal advice, and the specifics of any individual succession will depend on facts that only qualified Swiss counsel can assess. What can be said, as a matter of general observation, is that the 2023 reform has materially reduced a category of structural friction that previously complicated succession planning for a defined group of founders.
The removal of parental compulsory portions is not a dramatic legislative gesture. It is a precise, targeted adjustment to the allocation of testamentary freedom, and it has done what such adjustments are meant to do: extended autonomy to individuals in circumstances where mandatory claims from third parties served no compelling policy purpose.
For young founders, for the M&A advisors who structure their exits, and for the institutional buyers and family offices that acquire their businesses, this change is worth understanding clearly. The succession conversation has become, for this cohort, somewhat less complicated. That is a meaningful development, even if it arrived quietly.
