The Role of the Real Estate Agent — and Where It Differs from What You May Be Used To

If you've bought property in the United States, the United Kingdom, or Australia, the French property purchase system will feel structurally unfamiliar from the first step. The roles of the professionals involved — their relationships to the buyer, their legal obligations, and the scope of their authority — are defined quite differently from what you may have encountered elsewhere.

This is not a deficiency of the French system. It is simply a different architecture, built around a different allocation of risk, accountability, and legal responsibility. Once you understand who does what — and why — the process makes considerably more sense, and you are far better positioned to make use of the protections it offers.

A French property purchase is not a two-party transaction between you and the seller. It is a small ecosystem of specialists, each with a defined and fairly rigid role. They enter the process at different moments, they answer to different rules, and they carry different types of professional responsibility. Knowing who's who before you start is not a luxury — it directly affects how you communicate, what you can expect, and which professionals are actually working for you.

The agent immobilier

In the vast majority of French property transactions, there is only one real estate agent: the agent immobilier. This single agent represents the sale — not the buyer, not the seller in an adversarial sense, but the transaction itself. If you are buying in the UK, you are accustomed to the idea of a selling agent (who works for the vendor) and, potentially, a buyer's agent (who works for you, for a fee). In France, this bilateral structure is uncommon in residential transactions. There is typically one agent, and their mandate is with the seller.

The seller usually pays this agent — typically through a commission that is included in the advertised price, so that the "prix net vendeur" (the amount the seller actually receives) and the total price you pay as a buyer differ by the commission amount. In some transactions, particularly with certain types of mandate, the commission is charged separately and may be split between buyer and seller, or charged to one or the other exclusively. It is always worth clarifying exactly how the commission is structured in any transaction you enter into, because it has implications for how the price is negotiated.

The agent's mandate comes in two main forms. A mandat simple allows the property to be listed and sold by multiple agents simultaneously; the seller is not committed to any one agent. A mandat exclusif gives one agent the exclusive right to sell the property for a defined period, usually three months. From a buyer's perspective, a mandat exclusif means you're dealing with one agent regardless of where you found the property — you cannot "go around" the agent to reach the seller directly without the agent being entitled to their commission.

The agent's regulated activities in France are governed by the loi Hoguet of 1970, which requires agents to hold a professional licence (the carte professionnelle), to maintain professional indemnity insurance, and to hold any client funds in a regulated escrow account. An agent without a carte professionnelle is operating illegally. Asking to see an agent's carte professionnelle at the start of your relationship is entirely normal and entirely reasonable.

The dual position — paid by one side, bound to both

Here is where it gets nuanced, and where understanding the French framework properly gives you an advantage.

Although the agent's commercial mandate is with the seller — and the seller who pays their commission is technically the agent's client in a commercial sense — French law imposes a set of obligations on the agent that exist specifically to protect the buyer as well. These are not optional, and they are not merely ethical expectations: they are legal duties, breach of which gives rise to liability.

The most important of these duties is the devoir d'information — the duty of information. The agent is required to communicate all relevant information about the property to the buyer, including information that may not favour the sale. They cannot selectively disclose. This extends to information they have or ought to have: if the seller has told the agent about a recurring water infiltration problem, the agent is not entitled to withhold this from you on the grounds that it might deter you from buying.

Beyond the duty of information, the agent has a devoir de conseil — a duty of advice — which requires them to ensure that buyers understand the nature and implications of what they are signing. In practice, this means the agent should explain the key terms of the compromis, ensure you understand the conditions suspensives and what they require of you, and make sure you are aware of your rights during the délai de rétractation.

An agent who conceals a known problem with the property — a structural issue, a boundary dispute, an unauthorised extension — is not just behaving unethically. They are exposing themselves to legal liability in tort, and potentially to professional sanctions and loss of their carte professionnelle. This is a meaningful deterrent.

This dual position — paid by one side, legally bound to deal honestly with both — is worth understanding properly, because it shapes how you should communicate with your agent throughout the process. The agent is not your adversary. They are also not your unconditional advocate. They are a regulated professional with specific obligations to you that you can and should expect them to meet.

The notaire — the pivotal figure

The notaire is probably the professional most unfamiliar to foreign buyers, and the one whose role is most frequently misunderstood.

The notaire is not your lawyer. They are not there to advocate for your interests against the seller. The notaire is a state-appointed public officer — an officier ministériel — whose role is to ensure that the transaction is legally valid and that all the regulatory requirements of a property transfer are met. Their authority to authenticate legal documents — to make them legally binding and publicly enforceable — derives from the state, not from either party.

What the notaire is required to do: verify that the seller has good title to the property and the unencumbered right to sell; check for any mortgages, liens, or charges that must be discharged before title can transfer; confirm that no pre-emption rights are in play (notably the commune's droit de préemption urbain, which gives the local municipality the right to acquire the property at the agreed price before the sale to you proceeds); calculate, collect, and remit the transfer taxes (droits de mutation) and other regulatory fees; draft the acte authentique — the final deed — in legally compliant form; and register the transfer with the land registry (Service de la Publicité Foncière).

The fees charged by notaires are regulated by the state and are the same regardless of which notaire you use. The commonly quoted "frais de notaire" of approximately seven to eight percent of the purchase price for an older property are largely transfer taxes that the notaire collects and passes to the state — the notaire's own professional remuneration is a fraction of this total.

One important practical point: it is entirely possible, and in my view advisable, for the buyer to appoint their own notaire in addition to the seller's notaire. Both notaires will be involved in the transaction, both will review the documentation, and both will sign the final deed. Crucially, this does not cost more — the regulated fees are simply divided between the two offices. What it gives you is a notaire whose only client in this transaction is you, reading every document from your perspective, and available to answer your questions without any divided attention.

In practice, many foreign buyers do not appoint their own notaire — often because they are not aware that they can, or because the agent has presented the seller's notaire as "the notaire for the transaction." Both notaires are legally impartial, but having your own professional review means a second expert reading of everything before you sign.

The diagnostiqueur — the technical inspector

The diagnostiqueur is an independent technical inspector, accredited by the state and carrying professional liability insurance, whose job is to produce the dossier de diagnostic technique (DDT) — the mandatory bundle of surveys that must be annexed to any property sale.

The diagnostiqueur is appointed by the seller and paid by the seller, but their professional obligation is to accuracy and impartiality, not to producing reports that facilitate the sale. An accredited diagnostiqueur who knowingly misrepresents the condition of a property faces civil liability and can lose their accreditation.

The DDT typically covers: the presence of lead in paint layers (plomb), mandatory for properties built before 1949; the presence of asbestos-containing materials (amiante), mandatory for properties with a building permit issued before July 1997; the risk of termite infestation (termites), in designated risk zones as defined by arrêté préfectoral; the energy performance rating (DPE — Diagnostic de Performance Énergétique), which rates the property from A (most efficient) to G (least efficient) and has significant implications for future obligations; the safety of electrical installations more than fifteen years old; the safety of gas installations more than fifteen years old; the exposure to natural risks (flooding, landslides, seismic activity), industrial risks, and noise zones (ERNMT); and the condition of the non-collective sanitation system (assainissement non collectif) for properties not connected to mains drainage.

The DPE deserves particular attention for buyers considering older properties — and in France, "older" often means genuinely ancient. Properties rated F or G — colloquially called passoires thermiques (thermal sieves) — face increasing regulatory pressure. As of 2025, G-rated properties cannot have their rents increased if let, and there are upcoming prohibition dates on new tenancies for the worst-rated properties. Even for owners who have no intention of letting, the cost of bringing a poorly rated property up to a more acceptable standard can be very substantial.

When you receive the DDT — either before signing the compromis or shortly after — treat it as data, not as a formality to be filed away. A poor energy rating, a note about the presence of asbestos in certain materials, or a finding about the sanitation system should all go into your calculation of what the property is actually worth and what it will cost to own.

The bank — and the statutory timelines it imposes

If your purchase is conditional on mortgage financing, the bank becomes a central figure in the calendar of your transaction. Understanding the bank's role — and the statutory framework within which it operates — is essential for managing the timeline realistically.

The bank will require its own valuation of the property (expertise), typically carried out by an independent valuer on the bank's panel. This is not the same as the diagnostiqueur's technical reports — it is an assessment of the market value of the property, which the bank uses to determine how much it is willing to lend. If the bank's valuation is significantly lower than the agreed purchase price, this can create difficulties: the loan offer will be based on the bank's valuation, not your agreed price.

Once the bank has reviewed the complete file — your income documentation, your debt-service position, the property valuation, and the draft compromis — it will issue a formal loan offer (offre de prêt). By law, this offer must remain valid for at least thirty days. Also by law, you must wait at least ten calendar days after receiving the offer before you can formally accept it. This ten-day reflection period cannot be waived — it was introduced to prevent buyers being pressured into accepting financing they had not had time to consider.

French banks also apply strict debt-service-to-income ratios. The HCSF (Haut Conseil de Stabilité Financière) has set a maximum of 35% of gross income that can be committed to debt service. For buyers on pension income, this means the calculation is different from those still in employment — pensions are stable and predictable, which is generally viewed favourably, but the absolute level of income determines the ceiling. Working with a courtier (mortgage broker) who is familiar with the specific criteria of different French lenders can make a considerable difference to the terms you are offered.

The surveyor — the géomètre-expert

Occasionally, a surveyor (géomètre-expert) becomes involved in a French property transaction. This is typically where boundary questions need to be resolved — for land purchases, for properties where the cadastral plan does not match the physical boundaries, or where there has been a division of a larger plot that has not been correctly registered.

The géomètre-expert is a regulated professional with a formal role in establishing and certifying the boundaries of land. Where they are involved, their findings are authoritative and can resolve disputes that have been running between neighbours for years. Where a property you are considering involves land whose boundaries are unclear or disputed, a bornage — a formal boundary survey — is worth requiring before you commit.

For most apartment purchases and many straightforward house purchases, the géomètre-expert is not involved. But for rural properties, for properties acquired as part of a larger estate division, or for anything involving agricultural land, their role is worth understanding.

How these professionals work together — and where the gaps are

Each of these professionals enters the transaction at a different moment and communicates primarily within their own domain. The notaire and the agent communicate regularly about the timeline and the documents. The diagnostiqueur delivers their report to the seller, who passes it to the agent and then to you via the compromis annexes. The bank communicates almost exclusively with you, though the notaire will typically notify the bank when the conditions for drawdown are met. The géomètre-expert, where involved, typically delivers their survey to the notaire.

What this means in practice is that there is no single professional whose job it is to make sure you, as the buyer, understand what is happening across the whole transaction. The notaire's obligation is to the legal validity of the transaction. The agent's obligation is to complete the sale. The diagnostiqueur's obligation is to produce accurate technical reports. None of these professionals is specifically tasked with translating the French legal process into terms that make sense to a British, American, or Australian buyer navigating it for the first time.

This is precisely the gap that a buyer's adviser fills — someone who has been through the process many times, who communicates with each of these professionals on your behalf, who reads the diagnostics and the compromis and the notaire's draft deed with your interests in mind, and who can tell you when something is routine and when something warrants attention or negotiation.

At France Made Easy, we interact with all of these parties on a daily basis. We are familiar with the pitfalls as well as their legal obligations. The whole buying process in France is, in our experience, very secure — the law, in a systematic way, protects the buyer. But it can feel confusing and opaque when you come from a different legal tradition, and the professionals involved cannot always be expected to fill that gap for you unprompted.

What this means for you

Understanding the roles of these professionals does not make you a French property lawyer. It does make you a much better client, and a much better negotiator.

When you know that the agent has legal duties to you as well as to the seller, you know what questions you are entitled to ask and what information you are entitled to receive. When you understand that the notaire is a public officer rather than your advocate, you know to appoint your own notaire to represent your specific interests. When you recognise that the diagnostiqueur's reports are data rather than formalities, you know to read them rather than file them.

The French property system is not designed to catch foreign buyers out. It is designed to create a legally robust transaction in which all the relevant information is disclosed, all the relevant professionals carry defined responsibilities, and the ultimate transfer of ownership is authenticated by the state. The challenge for foreign buyers is not that the system is unfair — it is that it is unfamiliar.

The antidote to unfamiliarity is preparation. Know who you are dealing with, what their role is, and what you can reasonably expect from them. Ask the questions you are entitled to ask. Use the protections the law gives you — the conditions suspensives, the rétractation period, your right to appoint your own notaire. None of these rights expire or cost extra to exercise. They are there for your benefit: the only question is whether you know they are there.
