The VEFA (sale in future state of completion) represents the main method of acquiring a new home in France. Buying off-plan means committing to a property that does not yet exist, based on contractual documents, plans, and a descriptive notice. Several specific risks deserve careful analysis before signing a reservation contract.
Financial completion guarantee in VEFA: what it covers and what it excludes
The financial completion guarantee (GFA) is often seen as a total safety net. The actual limits of this guarantee are less known, and this is where a significant part of the risk lies for the buyer of a new home.
| Situation | Covered by the GFA | Not covered by the GFA |
|---|---|---|
| Financial failure of the developer | Funding for the work to make the building usable | Finishing touches, lifting of non-substantial reservations |
| Delivery delay | No coverage for late penalties owed by the developer | Late penalties (the developer’s own responsibility) |
| Defects noted at delivery | Not covered as such | Requires a separate action from the buyer (legal guarantees) |
| Non-substantial defects | Not covered | Remain the responsibility of the seller or the buyer |
According to an analysis published by Village de la Justice on October 5, 2026, the GFA only finances the work necessary for the completion of the building. Defects, minor reservations, and failing finishes are not within its scope.
The financial guarantor is also not automatically responsible for delivery delays. His own liability can only be engaged if he himself delays in implementing the guarantee. To delve deeper into these mechanisms, Technique Habitat’s real estate advice details the concrete situations that a buyer may face.
VEFA delivery delay: what recent case law changes
Delay is the most common risk in off-plan purchases. The contract sets a delivery date or quarter, but developers regularly invoke “legitimate causes” to justify a postponement without compensation.
The Court of Cassation now more strictly regulates these legitimate causes. A ruling from May 2, 2024, determined that the mere delay of a company working on the site is not sufficient, on its own, to justify the postponement of delivery.
Two rulings issued on April 30, 2025, clarified another point. Clauses related to bad weather are only accepted when they are based on objective and verifiable data. A developer can no longer simply invoke the weather without tangible evidence.
Delay clauses: points to check in the reservation contract
- The expected delivery date must be clearly stated, ideally a specific quarter rather than a vague formulation like “within a reasonable timeframe”
- The legitimate causes for suspension must be listed in a limiting manner, not an open one, and each cause must be documentable by the developer
- The late penalties provided in the contract must be expressed in amount or percentage per day or per month of delay, with an automatic application mechanism
- The clause related to bad weather must specify the weather thresholds retained and the source of the data used
A contract that remains vague on these points leaves the developer with a margin of interpretation unfavorable to the buyer.
Compliance of the delivered new home: frequent discrepancies from the descriptive notice
The delivered home must correspond to the descriptive notice attached to the sales deed signed at the notary’s office. In practice, discrepancies often concern materials, equipment, or surfaces.
Any discrepancy between the notice and the delivered property constitutes a non-compliance defect that the buyer can contest. The difficulty lies in the fact that some material substitutions are presented as “equivalent” by the developer, without the buyer being able to easily verify this equivalence.
Reservations at delivery: how to effectively formulate them
On the day of delivery, the buyer has a right of reservation. He can record in writing each defect noted (cracks, missing finishes, equipment absent or different from what was planned). The reservations must be precise and descriptive, not generic.
An additional month after the handover of keys allows for reporting defects or faults not visible during the first visit. Beyond that, legal guarantees (perfect completion, two-year guarantee, ten-year guarantee) take over, but with heavier procedures.
Solvency of the real estate developer: an underestimated risk in VEFA
The failure of the developer represents the most serious scenario. The progressive calls for funds follow the progress of the construction site, according to a schedule regulated by law. When the developer goes bankrupt during construction, the completion guarantee covers the completion of the work, but not ancillary damages.
The price paid for a new home in VEFA includes the cost of construction, the developer’s margin, and the costs related to guarantees. Checking the financial stability of the developer before signing the reservation deed helps mitigate this risk. Accessible elements include published balance sheets, the number of programs already delivered, and the reputation among previous buyers.
The theoretical protection offered by the legal framework of the VEFA does not always coincide with the reality of available remedies. The GFA does not cover defects or late penalties, and case law tightens the legitimate causes for postponement.
The compliance of the delivered property largely relies on the vigilance of the buyer on the day of delivery. A reservation contract read in full, reservations formulated precisely, and a developer whose solvency has been verified constitute the three concrete levers of protection.
