How a Property Purchase Works in Switzerland

The role of the notary

In Switzerland, all property transfers must be executed by a notary (notaire in French-speaking cantons, Notar in German-speaking cantons). The notary is a public official — not a private lawyer — who is responsible for verifying the legal status of the property, preparing the purchase deed, ensuring all conditions are met and registering the transfer in the land register.

Unlike in some other countries, the Swiss notary acts for both parties — not exclusively for the buyer or the seller. The notary's role is to ensure the transaction is legally correct and properly documented, not to advocate for either party's interests.

The land register

The Swiss land register (registre foncier) is the definitive record of property ownership, encumbrances, easements and restrictions. Every property in Switzerland is registered in the land register, and the register is publicly accessible. Before purchasing any property, buyers should obtain and review the land register extract for the specific property.

The land register extract shows the current owner, the property description, any mortgages or charges registered against the property, easements (rights of way, building restrictions) and any other registered encumbrances. A clean land register extract is an important indicator of a straightforward transaction.

The purchase deed

The purchase deed (acte de vente or Kaufvertrag) is the legally binding document that transfers ownership from seller to buyer. It must be executed before a notary and signed by both parties. The deed records the agreed purchase price, the property description, the conditions of sale and any special provisions agreed between the parties.

Once the deed is signed and the purchase price transferred, the notary registers the transfer in the land register. The buyer becomes the legal owner at the moment of registration — typically within a few days of signing.

Key differences from other countries

International buyers should be aware of several key differences between the Swiss process and processes in other countries. There is no exchange of contracts followed by completion — the Swiss process moves directly from offer to notarial deed. There is no cooling-off period after signing the deed. The notary acts for both parties, not exclusively for the buyer. And the purchase price is typically transferred to the notary's escrow account before signing, not on the day of completion.

These differences mean that buyers must complete all due diligence and arrange financing before the deed is signed — there is no opportunity to withdraw after signing without significant legal and financial consequences.
