Power of attorney for a property sale in Switzerland: how to sell your property remotely

This article gives practical answers to the key questions:

• Who can be given a power of attorney for the sale of a property?
• What form and mandatory details must be observed?
• What costs should be expected and what precautions should be taken?
• How does a remote sale work in practice?

Definition: what is a power of attorney for the sale of a property?

A power of attorney is a legal mandate by which the owner (the principal) authorises a trusted person (the agent) to represent them in a specific property sale. In practice, the power of attorney allows an agent to act on behalf of the principal and sign the documents needed to transfer the property.

It is not a general power of attorney, which would cover all of the principal's affairs. A power of attorney for the sale of a property is a special power of attorney: it concerns a specific transaction – for example the sale of an apartment in PPE or a villa – and not the principal's entire estate. The Swiss Code of Obligations requires a special power of attorney to sell real estate (art. 396 para. 3 CO). Without this special scope, the agent has no power to dispose of the property.

Depending on the extent of the powers granted, the agent may sign the preliminary sale agreement, the sale mandate given to the estate agent, or the notarised deed of sale. In practice, a power of attorney avoids costly travel and speeds up the transaction, while ensuring smooth coordination between notary, buyer, bank and broker.

Key points to remember:

• The principal remains the owner and final decision-maker
• The agent acts strictly within the limits of the document
• The power of attorney ends automatically when the deed is signed, or in the event of revocation, death or loss of the principal's capacity to exercise civil rights
• A power of attorney can be revoked by the principal at any time

When should a power of attorney be used for a property sale?

Granting a power of attorney is particularly suitable in several practical situations we frequently encounter at Millenium Properties SA:

• Geographical distance: an owner living abroad – London, Dubai, Singapore, New York – cannot return to Geneva for every stage of the sale. A power of attorney removes this obstacle.
• Inheritance and joint ownership: in an estate involving several heirs living in different places, a single representative is given power of attorney to sell the property on behalf of the joint owners, which greatly simplifies the procedure.
• Separation or divorce: a former spouse prefers to be represented to avoid confrontation during the sale of the marital home.
• Health or age: a person with full capacity of discernment but reduced mobility can grant power of attorney rather than travel to the notary.
• Incompatible schedule: executives, diplomats or professionals whose working lives make it impossible to attend on the signing date.

These situations apply equally to the sale of a high-end apartment, a villa or a rental building in the canton of Geneva or Vaud.

Who can be given a power of attorney for the sale of a property?

Any adult may grant a power of attorney, provided they have full legal capacity and capacity of discernment. The agent must also be an adult with legal capacity, not under general deputyship, and clearly identified by surname, first name, date of birth and address.

The agent must be a trusted person able to honour the principal's commitments. The power of attorney confers significant authority – accepting the sale price, signing the terms, binding the seller – hence the need for a careful choice.

Possible profiles on the seller's side:

• Family member: spouse, adult child, brother or sister
• Trusted lawyer or notary
• Long-standing friend
• Broker or representative of the appointed estate agency (for example a member of staff at Millenium Properties SA)

On the buyer's side, the purchaser may also grant power of attorney to their spouse, a relative or a member of staff at their bank to sign the deed of purchase.

In the specific case of sales by joint owners, each joint owner may grant power of attorney to the same person, provided all parties agree on the sale and the price.

Forms of power of attorney: private deed, authentication and Swiss requirements

A power of attorney may be drawn up as a private deed or notarised. Understanding the difference is essential to avoid rejection by the land registry.

A power of attorney by private deed is a document drafted and signed between private individuals, without involving a public officer. It is free of charge, including certification at the town hall in some countries. In French-speaking Switzerland, however, this form alone is not sufficient for a property sale.

An authentic power of attorney is drawn up before a notary. To be accepted, it must be in a form that meets Swiss requirements. A notarised power of attorney is recommended for maximum legal certainty, and is mandatory for certain property sales, notably the sale of buildings yet to be constructed. In practice, Swiss land registries and notaries require a special power of attorney with an authenticated signature.

The rules on powers of attorney vary by country and region. Here are the options depending on the principal's situation:

• In Switzerland: signature before a notary or authorised lawyer, who certifies the signature
• Abroad: signature at a Swiss embassy or consulate, or before a local notary with legalisation by apostille under the Hague Convention
• A power of attorney by private deed can be validated at the town hall in some countries, but this validation is generally not sufficient for the Swiss land registry
• Electronic signature: some Geneva notarial offices offer remote appearance by video conference combined with a qualified electronic signature, based in practice on a digital certificate recognised by the notarial office, but this practice is still emerging and subject to cantonal acceptance

Mandatory content: how to draw up a power of attorney for a property sale

A power of attorney must be in writing to be valid. A generic template found online is not enough: each situation requires a tailored document, and a poorly drafted or incomplete document may be rejected. It is therefore preferable for it to be drafted by the notary handling the transaction.

To draw up a power of attorney, you need a valid identity document, a written deed and the title deed to the property. The agent must also present a valid identity document when signing the deed.

The power of attorney must be precise and state the identity of the parties and the purpose of the transaction. The essential information is:

• Full identity of the principal: surname, first name, date of birth, address, copy of identity document
• Identity of the agent: the same identity details
• Precise description of the property: address, municipality, plot number or PPE unit, approximate surface area
• Sale price: exact amount or minimum accepted price, essential financial terms
• Reference to the draft deed or the preliminary sale agreement, where applicable

The power of attorney must specify the agent's powers: signing the preliminary agreement or reservation contract, accepting the price, setting the date of final signing, signing the authentic deed, and where applicable receiving the price into a specified account.

The power of attorney must specify the limits and duration of the powers granted to the agent. We recommend setting an expiry date – for example three months – so that an outdated document does not cause problems if the sale is delayed.

At Millenium Properties SA, we help sellers review the draft power of attorney, check its consistency with the sale mandate and the preliminary agreement, coordinate exchanges with the notary, and remain available for any questions about its content before signing.

Power of attorney, preliminary sale agreement and notarised deed: how a remote sale works in practice

Here is the typical sequence of a property sale with power of attorney in Geneva:

1. Property valuation by the agency and signing of the sale mandate. If the owner is absent, they can grant power of attorney to a relative or representative to sign this mandate.
2. Marketing, receipt and negotiation of offers. The seller approves the selected offer remotely.
3. Preliminary sale agreement: the power of attorney may include the authority to sign this preparatory document in place of the principal.
4. Signing the power of attorney: at the Swiss consulate, before a local notary with apostille, or at the Geneva notarial office.
5. Authentic deed: the agent signs at the notary's office. The notary checks that the power of attorney is compliant before the deed of sale is signed.
6. Registration in the land registry and transfer of the price.

Take a practical example: an owner living in New York sells her high-end apartment in central Geneva. She signs a special power of attorney certified at the Swiss consulate, authorising her Millenium Properties SA broker to sign the preliminary sale agreement and the final deed at a price of CHF 3'150'000.–. The notary sends the draft deed to the principal several weeks before signing, allowing her to approve each clause.

Digital tools – virtual tours, secure document exchange, electronic signature for certain mandates – streamline the whole process and strengthen remote representation.

Costs, validity and precautions to secure the power of attorney

In Switzerland, fees for authenticating a signature are set by cantonal law. In Geneva, signature certification fees generally range from CHF 15.– to CHF 100.– depending on the type of document. The cost of drafting the power of attorney is often included in the overall fees for the deed of sale.

By way of comparison, in other jurisdictions such as France, a notarised power of attorney costs around €32.65 excluding VAT. For two powers of attorney, the total cost is €65.30. Additional fees may be added to the cost of the power of attorney, depending on the complexity of the situation.

The power of attorney can be revoked by the principal at any time, in writing, addressed to the notary and the agent. It also ends in the event of death or loss of the capacity to exercise civil rights.

Our advice for avoiding disputes:

• Limit the power of attorney to a specific sale and a clearly stated minimum price
• Specify that the agent cannot change the price or main terms without prior written consent
• Keep a signed copy of the power of attorney and of all exchanges with the notary
• Read the draft deed carefully before the agent signs: once the sale is entered in the land registry, reversing it is extremely difficult

Millenium Properties SA secures each stage, informs the client about the implications of the power of attorney and coordinates with the notary so that the purpose of each clause is understood before the final commitment.
