How does usufruct (Nutzniessung) work for a surviving spouse in Switzerland?

Usufruct in favor of the surviving spouse under Article 473 of the Swiss Civil Code (ZGB) is one of the most powerful estate planning mechanisms available under Swiss inheritance law. Through this testamentary disposition, a deceased spouse can confer upon the surviving partner the lifelong right of use and enjoyment (usufruct / Nutzniessung / usufruit) over the entire estate share devolving upon their common children. Following the major Swiss inheritance law reform that took effect on January 1, 2023, the surviving spouse can now receive up to 1/2 of the estate in full outright ownership in addition to the lifelong usufruct over the remaining 1/2 (increased from the previous 1/4 limit).

In practice, Art. 473 ZGB is utilized primarily to protect the surviving spouse's home and financial security. The surviving partner can continue residing in the family chalet or apartment rent-free or lease it out and retain all rental proceeds. The common children receive "bare ownership" (nacktes Eigentum / nue-propriété) and cannot compel a buyout or demand cash payout of their statutory shares during the surviving parent's lifetime, eliminating the threat of a forced property sale.

1. Legal Framework: Art. 473 ZGB and the 2023 Inheritance Reform

Under Swiss statutory intestate succession (Art. 462 ZGB), a surviving spouse inherits 50% of the estate alongside children, while the children share the remaining 50%. If the primary asset is real estate, this co-ownership often creates severe friction. If the surviving partner lacks sufficient liquid funds to buy out the children's equity, the property must often be auctioned.

Art. 473 ZGB overrides this scenario. The 2023 Swiss inheritance reform greatly expanded the surviving spouse's financial power: testators can now allocate 50% in outright ownership and assign the lifelong usufruct over the remaining 50% to the spouse. This statutory mechanism legally subordinates the children's statutory shares (Pflichtteil) for the duration of the spouse's life, as detailed in our guide on Swiss forced heirship statutory shares.

2. Stepchildren and Swiss Tax Implications

A crucial legal nuance must be noted: Art. 473 ZGB usufruct is legally enforceable solely against common children of both spouses. If the deceased had children from a previous marriage or relationship (non-common descendants), those children retain an unencumbered statutory forced share in full ownership. An usufruct cannot be unilaterally imposed on them. Our dedicated guide explains in detail how to leave Swiss real estate in a will when blended families are involved.

Regarding taxation, the usufructuary is responsible for declaring the capital value of the real estate on their annual cantonal wealth tax return and must declare the imputed rental value (Eigenmietwert / valeur locative) or collected rent as taxable income. Conversely, mortgage interest and regular property maintenance costs can be deducted.

3. Comprehensive Swiss Estate & Personal Protection

Testamentary usufruct only becomes effective upon passing away. To protect your spouse during your lifetime in the event of cognitive decline, an Advance Healthcare Directive specifies medical instructions in advance, while a General Power of Attorney grants legal authority to manage banking and administrative affairs seamlessly. Where family loans have contributed to property financing, executing a formal Acknowledgment of Debt ensures clear accounting when opening the will.
