Exclusive Listing Agreement in Geneva: Benefits, Risks, Non-Exclusive Mandate

If an agency in Geneva asks you for exclusivity, you choose between an exclusive listing agreement and a non-exclusive mandate. It is Swiss brokerage law, a contract under which an intermediary is paid for having found a buyer (art. 412 et seq. CO), that applies, not French law.

This article covers what exclusivity commits you to, how it compares with the non-exclusive mandate, its advantages and disadvantages, selling directly yourself, and the risk of listing your property with several agencies. It then covers the choice based on your situation, negotiation, termination and commission.

What is an exclusive listing agreement?

An exclusive listing agreement is a contract under which you entrust the sale of your property to a single agency for an agreed period. Under Swiss law, it is a brokerage contract (art. 412 para. 1 CO).

The Code of Obligations does not provide for exclusivity: it is a clause of the contract that creates it. Through this clause, you undertake not to enter into another brokerage contract concerning the same property (Federal Supreme Court, ATF 100 II 361, consid. 3a).

Compensation follows the success rule: the broker is entitled to their fee as soon as their information or negotiation leads to the sale being concluded (art. 413 para. 1 CO), unless a clear clause states otherwise (ATF 131 III 268, consid. 5.1.2; ATF 113 II 49, consid. 1b). Unlike French law, Swiss law subjects brokerage to neither a minimum duration nor a written form requirement (art. 11 para. 1 CO).

What is the difference between a non-exclusive mandate and an exclusive mandate?

The difference between a non-exclusive mandate and an exclusive mandate is the number of agencies authorized to sell your property: several under a non-exclusive mandate, only one under an exclusive mandate, which determines who receives the commission.

Under a non-exclusive mandate, you can list your property with several agencies and sell it yourself; only the agency whose activity led to the sale is paid (art. 413 para. 1 CO).

Under a semi-exclusive mandate, you reserve the sale to a single agency but retain the right to find your own buyer (ATF 100 II 361, consid. 3); under Swiss law, this is the default regime, called simple exclusivity. Only an absolute exclusivity clause removes this right.

The following table compares the three arrangements on 7 decisive criteria.

Criterion	Non-exclusive mandate	Semi-exclusive mandate (simple exclusivity)	Absolute exclusive mandate
Several agencies appointed	Yes	No, only one	No, only one
Direct sale by the owner	Yes, without commission	Yes, without commission	No, prohibited
Agency paid	Whichever finds the buyer	The agency, unless a direct sale without its involvement	The appointed agency; in the event of a direct sale, damages or commission if the contract provides for it
Marketing funded by the agency	No, payment uncertain	Yes, in part	Yes
Single price across portals	No, discrepancies possible	Yes	Yes
Single point of contact for buyers	No	No, agency and owner	Yes
Flexibility for the seller	Yes, maximum	Yes, partial	No, reduced

The law does not set a commission rate for any of these arrangements (art. 414 CO).

What is the benefit of signing an exclusive mandate?

The benefit of signing an exclusive mandate is getting greater commitment from the agency: confident that no competitor will capture its commission, it invests in the sale.

Agencies seek exclusivity because, without it, only the broker whose activity succeeds is paid (art. 413 para. 1 CO), and their expenses are reimbursed only if the contract provides for it (art. 413 para. 3 CO).

You gain 4 advantages from exclusivity.

• Stronger resources: professional photos, a virtual tour and paid listings, provided the contract details these resources in a marketing plan.
• A single listed price: one listing per portal avoids price discrepancies between agencies, provided the price is based on a substantiated valuation.
• A single point of contact: the agency centralizes viewings, offers and negotiation, provided it gives regular written reports.
• A discreet sale: the agency presents a prestige property to its qualified buyers without a public listing, if its buyer database is real.

What are the disadvantages of an exclusive mandate?

The disadvantages of an exclusive mandate number 4, most linked to a single cause: the sale relies on a single agency for the agreed period.

The 4 disadvantages and their safeguard are as follows.

• A passive agency: the exclusive broker must act, but chooses its own means (ATF 103 II 129, consid. 3). Require a written marketing plan.
• An inflated valuation: a flattering price wins the signature, then the property stalls and the sale drags on. Compare two valuations.
• An extended term: tacit renewal prolongs the exclusivity; the principal may revoke it at any time (art. 404 para. 1 CO).
• A commission with no buyer found: a clause waiving the causal link requirement makes it due even if the agency found nothing (ATF 100 II 361, consid. 3c). Cross it out.

If you already have a buyer in mind, refuse absolute exclusivity: your direct sale depends on the clause.

Can you sell your property yourself during an exclusive mandate?

Yes, you can sell your property yourself during an exclusive mandate, unless the clause forbids it; a commission clause on direct sales makes the commission due.

Absent a clause to the contrary, exclusivity only prevents you from appointing another broker (ATF 100 II 361, consid. 3a), and any departure from the causal link requirement of art. 413 para. 1 CO must be clear (Federal Supreme Court, judgment 4A_449/2019).

Three ways of wording the clause change the answer.

• Simple exclusivity: direct sale allowed, commission not due, unless the agency introduced the buyer.
• Absolute exclusivity: direct sale prohibited (consid. 3b). The agency claims damages by proving its loss (art. 98 para. 2 CO; consid. 4), or the commission if the contract provides for it.
• Commission in the event of a direct sale: direct sale allowed, commission due without a causal link (consid. 3c), reducible if excessive (art. 417 CO).

These three summaries set out the three ways of wording the clause: for each, whether you can sell on your own and what you then owe the agency.

Attach to the contract the list of already-known buyers, excluded from the commission.

Why not list your property with several agencies?

Listing your property with several agencies weakens the sale: their competition degrades the presentation and perception of the property.

The 4 risks of the non-exclusive mandate are as follows.

• Inconsistent listings: each agency publishes its own listing; two different displayed prices signal room for negotiation.
• A "burned" property: a listing visible everywhere for weeks signals an unsold property.
• Two agencies for one buyer: the commission goes to the agency that introduced the buyer first, if that introduction led to the sale (art. 413 para. 1 CO; Federal Supreme Court, judgment 4A_529/2023). You bear the dispute.
• Minimal effort: a non-exclusive broker generally has no obligation to act, unlike the exclusive broker (ATF 103 II 129, consid. 3); each agency invests little.

The non-exclusive mandate suits a property in high demand and can be revoked at any time (art. 404 CO).

Exclusive mandate or non-exclusive mandate: which should you choose?

Choosing between an exclusive mandate and a non-exclusive mandate depends on four criteria: the type of property, discretion, a buyer already identified and local demand, with no arrangement being inherently superior.

• Atypical property: exclusive mandate if the property compares poorly with the market, because the exclusive broker is required to act (ATF 103 II 129).
• Discretion: exclusive mandate if the sale excludes any public listing, because a single broker chooses which buyers to contact.
• Buyer already identified: semi-exclusive mandate, with the buyer's name attached, if someone close to you expresses interest, because only absolute exclusivity prevents you from selling on your own (ATF 100 II 361).
• Standard property: non-exclusive mandate if the neighborhood has comparable sales, because you only pay the agency whose introduction succeeds (art. 413 para. 1 CO).

This decision tree starts from your situation and indicates, for each of the four cases, the recommended mandate and its reason.

The exclusive mandate suits a rare or confidential property, the non-exclusive mandate an ordinary one.

How do you negotiate an exclusive mandate?

Negotiating an exclusive mandate covers everything the law leaves open: duration, services, follow-on clause and exit terms.

No duration is set in the Code of Obligations; French-speaking Swiss agencies most often indicate 3 to 6 months, up to 12 months for an atypical property.

• Limit the duration, with no tacit renewal.
• Require a written marketing plan: portals, photography, price.
• Get a monthly report on viewings and offers.
• Limit the follow-on clause, which keeps the commission owed after the mandate ends, to a named list and a fixed period: in judgment 4A_529/2023, a one-year clause did not exempt the broker from the causal link requirement.
• Set the exit cost as actual expenses, since revocation remains free at any time (art. 404 CO).

Terminating the mandate and the agency commission complete these terms; selling without an agency and choosing the agency close out the decision.

Can an exclusive mandate be terminated at any time?

Yes, an exclusive mandate can be terminated at any time: the mandate is revocable at any time (art. 404 para. 1 CO), and this rule applies to brokerage (art. 412 para. 2 CO).

What the law says (art. 404 para. 1 CO): "The mandate may be revoked or repudiated at any time."

The Federal Supreme Court considers this a mandatory right, even where a clause bars revocation before a set date (ATF 103 II 129). Revoking at an inopportune time only requires compensating the damage caused (art. 404 para. 2 CO).

There is no irrevocable three-month period as under French law. The clauses of the real estate listing agreement set out the form the revocation must take.

What is the agency commission for an exclusive mandate?

The agency commission for an exclusive mandate in Geneva is 2% to 5% of the sale price, depending on the brackets of a scale published by a property management firm, with no statutory rate.

A Geneva property management firm (Esther Lauber, source consulted in September 2026) applies 3 brackets, excluding VAT of 8.1%.

• 5% on the first CHF 500,000.
• 3% on the portion between CHF 500,000 and 4 million.
• 2% on the portion above 4 million.

The French-speaking Swiss press puts common practice around 3% (GBNews, January 2022).

Exclusivity does not set any particular rate: the rate depends on the property's price and is negotiated before any signature. Unless otherwise agreed, the commission is due only on success, meaning when the broker's activity leads to the sale (art. 413 para. 1 CO).

Can you sell without an agency in Geneva?

Yes, you can sell your property in Geneva without going through an agency: no law requires a broker, and the deed of sale must take notarial form before a notary (art. 216 para. 1 CO).

By choosing to sell without an agency, you avoid the commission and set the price yourself. It is up to you to place the listings, organize viewings and negotiate with buyers through to the deed.

How do you choose which agency to give the exclusivity to?

To choose which agency to give the exclusivity to, first pick the one that proves recent sales comparable to your property, in the same neighborhood.

Then ask each candidate agency for its marketing plan, to compare the media used and the timeline. Finally, compare the valuations: the price proposed by the real estate broker must be based on actual transactions, and a figure noticeably higher than other opinions delays the sale. This evidence lets you decide between exclusivity, a non-exclusive mandate or a direct sale, rather than signing based on a promise.
