Inheritance law in Switzerland is governed by the Swiss Civil Code (ZGB). It determines who inherits a deceased person’s estate and how it is distributed.
In the absence of a will, statutory succession applies. In particular, the following persons are entitled to inherit:
The law sets clear limits through what are known as compulsory portions. Anyone wishing to actively plan their estate must take these mandatory claims into account.
The right to a compulsory share protects certain close relatives from being completely disinherited.
Those entitled to a compulsory portion are:
The compulsory portion is a legally guaranteed minimum entitlement to the estate. Only the so-called disposable portion may be freely disposed of. Anyone who disregards these limits risks subsequent actions for reduction and long-running inheritance disputes.
A will allows a person to unilaterally determine how their estate is to be distributed. Options include:
A will may be revoked at any time and must be drawn up in a legally valid form (holographic or notarised). A holographic will must be written entirely by hand from start to finish. It must also bear the date of execution and the testator’s signature.
It offers flexibility but does not create a contractual obligation between the parties involved.
You can find a template for a will here.
Upon death, a community of heirs is automatically formed. All heirs jointly become the owners of the entire estate.
Important consequences:
The division of the estate dissolves the community of heirs. This is done either by mutual agreement through a partition agreement or through the courts. Clear arrangements made during the testator’s lifetime significantly reduce the potential for conflict.
Complete disinheritance is only possible under strict legal conditions, such as in the case of serious criminal offences or grave breaches of duty towards the testator. Mere family tensions are not sufficient.
If disinheritance is declared without a legal basis, the claim to a compulsory share remains valid and can be enforced through the courts.
Usufruct allows a person to use an asset and receive its income without being the owner.
In inheritance law, it is frequently used to:
Usufruct is a tried-and-tested instrument for balancing the interests of spouses and children.
A contract of inheritance is a binding contractual arrangement between the testator and one or more persons. Unlike a will, it cannot be revoked unilaterally.
It is particularly suitable for:
Children in an inheritance contract
Children are generally entitled to a compulsory share. In an inheritance contract, they may:
Particularly where there are several children or a family business, an inheritance contract provides planning certainty and prevents future disputes.
Advantages of an inheritance contract
An inheritance contract must be notarised.
The executor is a person appointed by the testator to carry out the last will and settle the estate.
They are appointed in the will or in the inheritance contract and have the following duties in particular:
The executor acts independently and represents the estate in dealings with third parties. Appointing an executor is particularly advisable in the following situations:
A neutral and knowledgeable person acting as executor can help prevent disputes and ensure the estate is settled efficiently.
