Many self-employed professionals and sole proprietors assume their business can simply be kept running by family members or key employees until a will is probated or the estate is formally divided. The legal reality under Swiss law is entirely different: when the owner of an unincorporated business passes away, the enterprise faces complete operational paralysis within weeks. Even companies with healthy order books and solid bank balances routinely spiral into existential crises during this transition.
The fundamental issue lies in the legal nature of a sole proprietorship. Unlike a corporation (AG) or a limited liability company (GmbH), it lacks an independent legal personality. Operating assets, client agreements, accounts receivable, and business bank accounts form a single legal entity with the owner’s private estate. Upon death, the principle of universal succession pursuant to Art. 560 of the Swiss Civil Code (ZGB) takes immediate effect: all assets and liabilities pass undividedly and instantaneously to the community of heirs.
This marks the start of a perilous interim phase between the date of death and the formal issuance of the certificate of inheritance (Erbschein). Once a financial institution is notified of a client’s passing, routine policy dictates that the accounts are frozen immediately. A widespread misconception is that an ordinary bank power of attorney designated to remain valid “beyond death” offers reliable protection. In practice, banks act with extreme caution to shield themselves from liability claims by potential heirs. As a rule, releases are restricted to immediate funeral expenses, leaving payroll, commercial rent, and urgent supplier invoices entirely blocked.
Months often pass before the heirs obtain legal authority to act. Disposition over estate accounts belongs exclusively to the heirs acting jointly, and only upon presenting an official certificate of inheritance. Because probate authorities must first observe the statutory three-month disclaimer period, obtaining this document typically takes three to six months. If the relatives are uncertain about the financial solvency of the business and request a public inventory (öffentliches Inventar) under Art. 580 et seq. ZGB as a protective measure, the public call to creditors routinely extends this administrative standstill beyond six months. Throughout this period, the business lacks the operating liquidity required to survive.
Faced with this emergency, families frequently stumble into the liability trap of “intermeddling” under Art. 571 para. 2 ZGB. Hoping to rescue the business, relatives intervene on their own initiative to fulfill client orders or handle daily operations. If their actions exceed the strict boundaries of purely preservative administrative measures, the law treats this conduct as meddling in estate affairs. The consequence is severe and irreversible: the individuals forfeit their statutory right to disclaim the inheritance. Should the enterprise ultimately prove over-indebted, the heirs become personally, jointly, and severally liable with their entire private wealth for all outstanding business debts.
Preventing such an operational vacuum requires proactive estate planning during the owner’s lifetime. Structurally, the most robust safeguard is incorporating the business into a separate legal entity, such as a GmbH or an AG. Commercial contracts, bank accounts, and employment relationships remain with the company, ensuring continuity through registered managing directors or authorized signatories.
If the sole proprietorship is to be retained, appointing a commercially experienced executor (Willensvollstrecker) by testamentary disposition is indispensable. An executor can promptly obtain an official certificate of executorship, assume control of operations, and process urgent disbursements without waiting for unanimous consent among all heirs. To bridge acute, short-term liquidity bottlenecks, establishing a joint account (compte-joint) with a trusted proxy featuring independent, single-signature authority offers practical interim relief.
The situation is particularly urgent for regulated liberal professions, including physicians, dentists, attorneys, and fiduciaries. Mandates and patient contracts generally terminate upon death, triggering immediate statutory obligations regarding professional secrecy, file retention, and patient data protection. Entrepreneurs who fail to establish clear deputy arrangements and depository instructions in advance leave their life’s work exposed to sudden legal and financial paralysis.
