The Brokerage Agreement in Thessaloniki & Halkidiki

The Brokerage Agreement in Thessaloniki & Halkidiki: Five Risks, Two Markets

The first legal document you sign in a property purchase in northern Greece is not the purchase contract. In Thessaloniki, it can cover a developer's entire portfolio without naming a single apartment. In Halkidiki, it can trigger a commission obligation before you have had time to commission a single legal check. Here is what to read before you sign.

A buyer from Istanbul arrives in Thessaloniki for a long weekend. A professional agent takes them to see a newly completed apartment in Kalamaria. Before entering the building, a viewing form is placed on the car bonnet. The agent turns to the signature page.

The apartment is not quite right. The buyer contacts the developer directly three weeks later — there is a larger unit in a different building in Pylaia. The developer confirms the price. An agreement is being finalised.

Then a letter arrives from the original agency.

The viewing form contained two clauses the buyer had not read. The first: commission was owed from the moment a Preliminary Agreement was signed. The second: the form covered not just the Kalamaria apartment but "any property developed or co-owned by" the above vendor. The buyer had signed a form that attached a commission obligation to an entire developer’s portfolio — before they had seen a second building, and well before any agreement had been reached.

This is not an unusual scenario. It is what happens when a standard pre-printed form is signed without review — and it is specifically a Thessaloniki risk.

What a Brokerage Agreement Actually Is — and Why the Standard Template Is Not Neutral

A Brokerage Agreement or Viewing Form is a binding legal contract. By signing it, you agree to pay the agent’s commission under the conditions it defines. It is not a courtesy record and it is not a formality. It is the first contract in your property purchase — and in the Thessaloniki and Halkidiki markets, it is the one most frequently signed without review.

Professional agencies use transparent, well-drafted agreements. But many standard pre-printed templates were not written with the buyer’s interests in mind — and they are presented at the moment of least scrutiny: before the viewing, when attention is on the property, not the paperwork.

In northern Greece, the same five problematic clauses appear repeatedly. What is distinctive about this market is how each one manifests differently depending on whether you are buying in urban Thessaloniki or on the Halkidiki peninsula.

These risks do not all activate at the same moment, and they do not all affect the same buyer profile. Understanding which applies to your specific situation is the first step.

Risk 1: Commission Before Your Due Diligence Is Complete

Both Markets

Many standard viewing forms require 50% or the full commission at the moment a Preliminary Agreement is signed. A Preliminary Agreement is a promise to buy — not a completed property transfer. What makes this risk distinctive in this market is the timing of when that Preliminary Agreement tends to be signed.

The Thessaloniki variant: off-plan timing

In Thessaloniki’s new-build segment — Kalamaria, Pylaia, the eastern development corridor — buyers frequently sign Preliminary Agreements early in the process, sometimes before an independent legal and technical check has been completed. If the viewing form triggers a commission payment at that stage, and the subsequent due diligence reveals a building irregularity, a cadastral discrepancy, or a title problem that leads to withdrawal, the prepaid commission becomes a separate recovery dispute rather than a straightforward refund.

The Halkidiki variant: summer signing before any verification

In Halkidiki, the risk is created not by the off-plan market but by the holiday buying pattern. A buyer who decides to purchase during a summer visit signs the Preliminary Agreement — and triggers the commission payment clause — before returning home. Independent legal and technical due diligence only begins afterwards. In Halkidiki, where forest map classifications and coastal zone boundaries are material to the value of what is being purchased, this sequence can produce a commission payment that precedes the discovery of a problem that would have prevented the purchase entirely.

Legal position: Under Article 703 of the Greek Civil Code, the default position is that a broker’s commission is earned when the final, definitive transfer contract is successfully concluded as a direct result of the broker’s mediation. Contract wording can materially alter the practical position. That is why payment timing should be addressed before signing, not after.

Risk 2: The Developer Portfolio Lock-in

Thessaloniki

This is the defining brokerage risk of the Thessaloniki new-build market — and it has no equivalent in the Peloponnese or, to the same degree, in Athens. In a market where a single developer may hold four or five projects across Kalamaria, Pylaia, and the eastern suburbs, a vaguely drafted Clause 2 provision can turn one viewing form into a commission obligation across an entire portfolio.

For a buyer comparing units across a developer’s portfolio — standard practice in Thessaloniki’s new-build market — a single carelessly signed form can eliminate the freedom to approach that developer through any other route.

Legal position: The Areios Pagos requires a strict causal link between the broker’s specific introduction and the final purchase. A commission is not owed simply because a buyer encountered an agent before purchasing from the same developer. But the protection of this principle, if tested in court, is far less reliable than a precisely drafted clause. Before signing, ensure the viewing form identifies the specific apartment by building address, floor, and unit number. Any reference to "other properties of the vendor" should be explicitly removed before you sign.

Risk 3: The August Double-Agency Commission Dispute

Halkidiki

Halkidiki’s holiday buying pattern creates a brokerage risk that is especially visible in this market: two agencies showing the same property to the same buyer in the same week, both holding signed viewing forms, and both presenting commission claims when the transaction closes.

In the Halkidiki market, where the same desirable property frequently circulates across multiple agencies on open listings, this is not a rare misfortune. It is a structural feature of the market. The protection is to verify, before signing any second viewing form, whether the property is already covered by a form you have previously signed. Your independent lawyer can make this determination before you commit.

Legal position: Where two valid viewing forms exist for the same property and the same buyer, the question of which agency is entitled to the commission is determined by the causal link between each agent’s specific introduction and the eventual purchase. But the process of establishing that link — if disputed — is the buyer’s problem to navigate in the middle of a transaction they are trying to complete.

Risk 4: The Property That Cannot Be Precisely Identified

Halkidiki

Coastal and rural properties on Sithonia and in the inland areas of Kassandra are frequently marketed without a precise cadastral reference. A viewing form that describes the property as "a beachside plot near Sarti" or "a stone house in the area of Vourvourou" creates a scope problem with direct consequences: if the form has a broadly drafted "same owner" clause and the property is not identified by its cadastral number, the obligation can extend to adjacent parcels, related titles, or co-owned land the buyer never saw.

This risk is structurally identical to the rural property identification problem in the Peloponnese — but in Halkidiki it intersects with the coastal zone classification. If a coastal plot is described only by location and the legal boundary of the State-owned coastal zone has not been established precisely in the deed, the viewing form’s scope may extend across property boundaries that neither buyer nor agent was aware of.

Legal position: Every viewing form should identify the property by its cadastral number and Land Registry reference. In Halkidiki’s coastal market, where street addresses do not exist for rural parcels, this is the only reliable means of defining the agreement’s scope. A form without it carries an identification problem that is worth resolving before you sign — not after.

Risk 5: The Corporate and Family Liability Clause

Both Markets

To prevent buyers from bypassing the agency by purchasing through a connected party, viewing forms often extend commission liability to family members, spouses, and companies associated with the buyer. For most residential buyers, this is a theoretical concern. For two specific buyer profiles that are central to the Thessaloniki and Halkidiki markets, it is not.

The Thessaloniki dimension: Golden Visa corporate structures

Turkish and Israeli investors purchasing in Thessaloniki — particularly those pursuing the Golden Visa programme through the €250,000 commercial-to-residential exception or the standard €800,000 threshold — frequently acquire through a Greek Private Company or SA for tax efficiency, visa eligibility, or inheritance planning. A viewing form signed by the individual buyer that extends commission liability to "any company in which the buyer holds an interest" can create an obligation for a pre-existing investment vehicle that has no connection whatsoever to the property being viewed. The acquisition structure is typically determined months before the property is found, by independent legal and tax advice. A blanket clause in a viewing form should not reach it.

The Halkidiki dimension: family purchase structures

Balkan buyers — from Serbia, Bulgaria, North Macedonia — sometimes purchase with a family member or through a family arrangement for inheritance or financial planning reasons. A broadly drafted clause extending commission liability to "family members" or "any person connected to the buyer" can hold the original viewer liable for a commission even if the final purchase is made by a family member acting entirely independently, through a separate transaction they initiated themselves.

Legal position: Greek courts may recognise the concept of economic identity where a buyer and purchasing entity are effectively the same for circumvention purposes. At the same time, an overly broad extension of liability can raise consumer-law concerns. If your intended ownership structure involves any company or family arrangement, this clause requires precise review and, if necessary, negotiation before signing.

A Note on Article 703 of the Greek Civil Code

Article 703 of the Greek Civil Code establishes that a broker’s commission is earned only when the final, definitive transfer contract is successfully concluded as a direct result of their mediation. This is the default statutory position.

It is the default statutory position. If the viewing form you sign sets out different conditions — payment at the Preliminary Agreement stage, commission on the same owner’s other properties, or liability extended to your company — the written wording of the form may materially affect your position. Article 703 is therefore a starting point, not a substitute for reviewing the contract you are asked to sign.

The protection that Article 703 offers is a reasonable default for anyone who did not sign a more demanding contract. For anyone who did sign one: the time to address the terms was before signing. This is why independent legal review of the viewing form is a first step, not an afterthought.

Before You Sign: A Practical Checklist for Thessaloniki and Halkidiki Buyers

These checks apply regardless of which zone you are buying in. Some are universal; others are specific to where you are.

• Does the form trigger any commission payment before the final notarial deed is signed — including at the Preliminary Agreement stage? If so, is this discussed and agreed in writing before signing?
• Does the form identify the specific property with absolute precision — exact address and unit number in Thessaloniki, cadastral reference and Land Registry reference in Halkidiki? Or does it refer vaguely to "any property of the same vendor"?
• If you are buying in Thessaloniki from a developer with multiple buildings: does any clause extend the commission obligation to other properties in that developer’s portfolio?
• If you are in Halkidiki: have you already signed a viewing form with another agency for this property, or for a property that could overlap with this one?
• Does the form have a clearly defined expiration date — and is the tail period specified in writing? In Halkidiki, where properties leave the market each September and return each spring, an open-ended form that carries over between seasons is a meaningful exposure.
• If you are purchasing through a company or family arrangement: does the liability clause precisely define the circumstances in which that structure triggers commission — or is it a blanket extension to anyone connected to you?

If any of these raises a question you cannot answer with certainty, your independent legal team should see the form before you sign — not after.

Reading and Negotiating Before You Sign

A brokerage agreement is a contract. Its terms can be discussed before signing. Professional agencies in Thessaloniki and Halkidiki are generally accustomed to dealing with informed buyers — a buyer who reads the viewing form carefully signals exactly the kind of client a serious agency wants to work with.

If a clause requires commission at the Preliminary Agreement stage, ask for alignment with the final notarial transfer. If the developer’s portfolio is broadly covered, ask for the specific unit to be identified precisely and the broader clause removed. If the property in Halkidiki is described only by location, ask for the cadastral reference to be inserted. If the tail period is absent or open-ended, ask for a specific date in writing.

These are reasonable requests. How an agent responds to them is informative in itself.
