Breaches his duty to advise

📅 Décision du 09 July 1980⚖️ Cour de cassation📖 2 min de lecture

An estate agent breaches his duty to advise where, having been instructed by his client to find him a plot of land for the construction of a dwelling of a specific type, he omits to consult the planning certificate and the documents relating to the property transaction, namely the site plan and the subdivision specifications, through which he would have obtained from the project manager all desirable details, and leaves his client, a layperson in the matter, to resolve this issue by sending him a letter which, by its general wording, constitutes an invitation to purchase, whereas the rules governing the subdivision prohibited any construction of the model chosen by the client.

Cas d'usage pratiques

1

First-time buyer misled on buildable plot in Bordeaux

In 2023, Claire, a first-time buyer from London, instructed a French estate agent in Bordeaux to find a plot for a timber-frame house. The agent recommended a 600 m² plot in a subdivision (lotissement) in Eysines, near Bordeaux, for €120,000. Claire received a generic letter from the agent saying the plot was suitable, but the agent never consulted the planning certificate or the subdivision's restrictive rules (cahier des charges), which banned timber-frame construction.

Application pratique:

Under this case law, the estate agent breached his duty to advise by failing to check the planning certificate and subdivision specifications before sending the letter. Claire should have requested these documents before signing the preliminary contract (compromis de vente). She can now claim damages from the agent for the loss, such as the extra cost of building in masonry instead of timber. She should keep the agent's letter, all emails, and the subdivision rules, and contact a French property lawyer.

2

Landlord selling plot with hidden building restriction in Nice

Marc, a landlord in Nice, owns a 400 m² plot in a gated subdivision. He instructs an estate agent to sell it as suitable for a two-storey villa with a flat roof. The agent markets it without checking the subdivision regulations, which actually prohibit flat roofs. A buyer signs a reservation contract, then discovers the restriction and pulls out, losing Marc a €450,000 sale and causing six months of delay.

Application pratique:

The agent's failure to consult the planning certificate and subdivision specifications before advertising constitutes a breach of the duty to advise. Marc should have required the agent to produce these documents before marketing. He can now seek indemnity from the agent for the lost sale and additional costs, as the agent's negligence caused the misrepresentation. Marc should preserve all marketing materials and correspondence to support his claim.

3

Co-owner blocked from adding extension in Lyon subdivision

Sophie, a co-owner in a subdivision (lotissement) in Caluire-et-Cuire, near Lyon, wants to add a ground-floor extension to her house. She asks the estate agent who manages the estate to confirm feasibility. The agent sends a brief email saying 'no problem' without checking the subdivision's restrictive rules (cahier des charges), which ban any extension beyond a certain height. Sophie spends €15,000 on architect's plans, then the co-ownership association refuses permission.

Application pratique:

This case law shows that the agent's duty to advise includes actively consulting planning certificates and subdivision documents, not just sending generic assurances. Sophie should have demanded written confirmation based on the actual documents. She can hold the agent liable for the wasted architect's fees and any other costs, as the agent's failure to check the rules directly caused her loss. She should gather the agent's email, the subdivision rules, and proof of expenses.
