A buyer signs a sales agreement for a house, secures their loan, and discovers three weeks before the final deed that the town is exercising its right of preemption. The property slips away from them. This scenario, far from being rare, illustrates how a real estate transaction can hinge on a legal detail that neither the seller nor the buyer had anticipated.
Urban preemption right: the risk that buyers underestimate
When purchasing a property located in a preemption zone, the municipality has a legal period to substitute itself for the buyer. The declaration of intent to alienate (DIA) is sent by the notary to the local authority, which can then decide to acquire the property instead of the initial buyer.
It is recommended to check the preemption zoning even before making a purchase offer. This verification can be done with the town’s urban planning department or through the notary.
If the municipality preempts, the buyer has no recourse to force the sale in their favor. They lose the property, the time spent processing the file, and sometimes the costs incurred for diagnostics or loan arrangements.
On the seller’s side, the price offered by the local authority may be lower than the price agreed upon with the buyer, and negotiating with a town hall is nothing like a classic negotiation between individuals. Professionals who assist transactions in tight markets, like those listed on https://www.proximmonet.fr/, incorporate this verification right from the mandate stage.
Suspensive clause for mortgage loan: the pitfalls of wrongful default
The suspensive condition for obtaining a loan protects the buyer: if financing is denied, they recover their deposit. In theory, it’s a safety net. In practice, a poorly conducted loan application can turn this protection into a trap.
Recent case law (Civ. 3e, 2026) confirms that a buyer who allows the suspensive condition to expire without having genuinely sought financing, or who deliberately sabotages their loan application, can be considered wrongfully in default. The seller can then demand the payment of the penalty clause stipulated in the agreement, which generally represents a significant percentage of the sale price.
To protect themselves, three points should be checked before signing the agreement:
- The timeframe for the suspensive condition must be realistic in relation to current banking processing times, which are often longer than a few years ago due to strengthened internal procedures.
- The buyer should submit loan applications to multiple institutions and retain all proof of submission (acknowledgments of receipt, confirmation emails).
- The characteristics of the sought loan (amount, duration, maximum rate) must be precisely described in the agreement to avoid any ambiguity regarding the compliance of a refusal.
An informed seller will ask their notary to draft a detailed suspensive clause. A vague agreement regarding financing exposes both parties to litigation.
Real estate telemarketing: what changes since the Cazenave law
Since law n° 2025-680 of June 30, 2025, a real estate professional can no longer call an individual to offer their services without having first obtained explicit and traceable consent. The Bloctel system, which operated on an opt-out basis, is replaced by an opt-in regime.
In practical terms, this means that the agency or representative must prove that the consumer has checked a box, filled out a form, or taken a clear positive action authorizing telemarketing. These provisions came into effect on August 11, 2026.
The penalty is severe: any contract concluded following irregular telemarketing is null and void. For a seller, this means that a sales mandate signed after an unsolicited call can be canceled, with cascading consequences on the ongoing transaction. For a buyer, a business relationship initiated by phone without their prior consent is contestable.
It is advisable to systematically check the conditions under which a professional made contact. If an agent called you without your written consent, the mandate they propose is based on a legally fragile foundation.
Diagnostics and legal documents: checks that avoid cancellation
The temptation to rush through the diagnostics step to speed up the sale is great. Feedback on this point varies, but one thing remains constant: an incomplete or outdated diagnostic file exposes the seller to a price reduction action, or even to a complete cancellation of the sale.
Documents to gather before the first visit:
- The energy performance diagnosis (DPE), mandatory for any real estate advertisement, with a validity period that varies depending on the date of completion.
- The state of natural, mining, and technological risks, updated according to the municipality.
- The asbestos diagnosis for properties built before a certain date, the lead exposure risk report for older homes, and the termite diagnosis in areas affected by prefectural order.
- The Carrez law measurement for co-owned lots, where an error exceeding the legal threshold entitles the buyer to a price reduction.
A seller who presents a complete file at the time of signing the agreement significantly reduces the risks of delays at the notary. Preparing diagnostics before putting the property on the market shortens the overall transaction time by several weeks.
The real estate market rewards administrative rigor as much as fair pricing. A valuation consistent with the local market, an agreement drafted without ambiguity, up-to-date diagnostics, and vigilance regarding recent legislative changes form the foundation of a transaction that proceeds to the final deed without a hitch.
