Estate planning involves consciously and systematically arranging the transfer of one’s assets during one’s lifetime, in the event of death or subsequent incapacity.
It encompasses legal, financial and personal measures, with the aim of:
Without clear arrangements, statutory succession applies. This often does not correspond to individual wishes and can lead to complex communities of heirs and protracted disputes.
A well-thought-out plan comprises several components:
Disposition of property upon death
The foundation is a will or an inheritance contract. This allows you to:
Particularly in the case of spouses, a combination of a marriage contract and an inheritance contract is often chosen to provide the surviving partner with the best possible security.
Further information on inheritance law can be found here.
Advance Care Directive and Living Will
Just as important as estate planning is making arrangements in the event of incapacity. If a person becomes incapable of making decisions (e.g. due to an accident, dementia, etc.), a previously appointed trusted person can take over their financial and personal affairs.
Tax planning
Inheritance and gift taxes are regulated at cantonal level in Switzerland. Spouses and children are tax-exempt in many cantons, whilst distant relatives or third parties may face significant tax liabilities.
Property and asset structure
Property, business holdings or larger assets require special planning. Unregulated circumstances often lead to deadlocks within the community of heirs.
A clear succession structure prevents forced sales or family conflicts.
Digital estate planning
Digital assets and the rules governing access to them should also be regulated. These include, for example, passwords, online accounts, bank accounts, digital subscriptions, etc.
A structured approach is crucial:
1. Taking stock
Identify your assets, liabilities, shareholdings and family circumstances.
2. Defining objectives
Clarify who you wish to benefit and what your priorities are (providing for your spouse, treating children equally, ensuring the business continues, etc.).
3. Checking statutory inheritance rights
Check which legal restrictions apply.
4. Choosing legal instruments
Decide between a will, an inheritance contract or a combination with a marriage contract.
5. Regular review
Adapt your plan to changing life circumstances (marriage, divorce, birth of children, changes in assets).
