Exoneration from Registration Duties: When an Erroneous Planning Certificate Causes Loss of Tax Advantage

Picture the scene: you are in Mougins, about to sign the deed of purchase for a magnificent plot of land, with a view of the hills. You have a planning certificate in your pocket telling you the land is buildable. You even undertake to build a house there within four years, to benefit from an exemption from registration duties (the tax paid on purchase). Everything seems perfect. But six months later, you submit your planning application… and the town council refuses it. Why? Because a local plan, approved even before your purchase, had classified your land as a Droit de préemption - Cecile Zakine">deferred development zone, an area where construction is virtually impossible. Result: no house, and above all, the tax authorities demand the registration duties you thought you had saved. You cry force majeure: “It’s not my fault, the planning certificate said the opposite!” But the Court of Cassation, in a judgment of 20 February 1978, decided otherwise. This decision, nearly half a century old, remains extremely relevant for any purchaser of land in Le Cannet, Mougins or elsewhere. It reminds us of a golden rule: in planning matters, a planning certificate is not an absolute guarantee, and the local plan always prevails. But then, how do you avoid falling into this tax trap? That is what we will look at.

The facts: a story that happens every day

Mr X, a property owner in Le Cannet, buys a plot of land in 1971 to build his main residence. At the time, Article 691 of the General Tax Code (CGI) allowed an exemption from registration duties and land publicity fees (broadly speaking, notary fees) provided that the purchaser undertook, in the deed of purchase, to carry out residential construction within four years. In return, the purchaser had to pay VAT on the land. Mr X therefore signs a deed in which he undertakes to build. He even obtains a planning certificate (a document indicating whether land is buildable) confirming that the land is buildable. So far, so good.

But then: when he submits his planning application, the town council refuses it. Why? Because a local plan of the municipality, approved on 9 March 1970, before the purchase, had created a “deferred development zone” (ZAD). In jargon, a ZAD is an area where development is frozen pending a development project. In other words, the land was buildable on paper according to the planning certificate, but not in reality, because the local plan, which has superior legal force, prohibited any construction. Mr X cannot therefore build within four years.

The tax authorities then demand the registration duties they had suspended. Mr X challenges this before the courts. He invokes force majeure: according to him, the erroneous planning certificate misled him, and the refusal of permission was unforeseeable. The Court of Appeal rules in his favour. But the tax authorities appeal to the Court of Cassation. And the Court of Cassation quashes the judgment, criticising the lower court for not having addressed the tax authorities’ argument: the local plan approved in 1970 was prior to the purchase, so the refusal of permission was foreseeable. In other words, Mr X should have checked the local plan himself, and not relied solely on the planning certificate.

The reasoning of the court – analysed

The central question was whether the refusal of planning permission constituted a case of force majeure (that is, an unforeseeable, irresistible and external event) which exempted Mr X from the obligation to build within four years, and therefore from the obligation to pay the duties.

The Court of Cassation answered no, and for a precise reason: the local plan of the municipality, approved on 9 March 1970, was prior to the deed of purchase (1971). This plan had created a deferred development zone in which the land was included. Now, a deferred development zone is public information, accessible to any purchaser by simply consulting the town hall. Therefore, the refusal of permission was not unforeseeable: Mr X should have known about it before buying. In other words, force majeure is not established because the event was foreseeable.

The Court also criticised the Court of Appeal for not having addressed the conclusions of the tax authorities which invoked this plan. In law, judges must address all arguments of the parties. By failing to do so, the Court of Appeal violated Article 455 of the Code of Civil Procedure (former).

On the merits, Article 691 of the CGI (in its version then in force) made the exemption subject to two conditions: (1) the undertaking given in the deed to build within four years, and (2) proof of completion of the works within that period, except in cases of force majeure. Here, the condition of force majeure not being satisfied, the exemption was lost.

This decision confirms previous case law: the courts are strict on the notion of fiscal force majeure. A simple change in regulations between the purchase and the planning application is not necessarily unforeseeable, especially if the local plan was already in force. On the other hand, if the plan had been amended after the purchase, force majeure could have been admitted.

What few people know is that this case illustrates a conflict between two documents: the planning certificate, which is an informative document, and the local plan, which is a regulatory document. The former does not create definitive rights, unlike the latter. In other words, a positive planning certificate does not guarantee that construction will be authorised if the local plan prohibits it.

What this means for you – practically

This decision has direct implications for all those who buy land with the intention of building, hoping to benefit from a tax exemption.

For the land purchaser: If you sign a deed where you undertake to build within four years to save registration duties (which can be 5 to 6% of the price, i.e. €15,000 on a plot costing €300,000), you must absolutely check the local plan before buying. Do not rely solely on the planning certificate. Go to the town hall, consult the Local Plan (PLU) or the Land Use Plan (POS). If the land is in a deferred development zone, think twice. And if you buy anyway, know that the refusal of permission will not be considered a case of force majeure if the plan predates the purchase.

For the land seller: You must inform the purchaser of the existence of the local plan and any restrictions. If you do not, you could be sued for fraudulent misrepresentation or hidden defects. For example, in Mougins, where prices are high, non-buildable land can be worth two to three times less than buildable land.

For the notary: They have a duty to advise. They must draw the purchaser’s attention to the local plan and the risks. If they do not, their liability may be engaged. undefined, I have come across cases where the notary failed to check the PLU, and the purchaser ended up with non-buildable land and a tax debt.

For the tax authorities: They will systematically check whether the works were carried out within four years. If not, they will demand the duties plus late payment interest (0.20% per month).

In summary, this decision requires you to be vigilant. A favourable planning certificate is not an absolute guarantee. The local plan always prevails.

Four tips to avoid this type of dispute

• Consult the PLU before buying: Do not settle for the planning certificate. Go to the town hall or the municipality’s website (for example, Le Cannet or Mougins) to consult the Local Plan. Check the zoning and applicable rules. If the land is in an agricultural, natural or ZAD zone, refrain or negotiate the price accordingly.
• Include a condition precedent in the preliminary contract: Draft a clause making the purchase conditional on obtaining planning permission. Thus, if permission is refused, you can cancel the sale without penalty. This is an essential safety net.
• Check the date of the local plan: If the plan was approved before your purchase, any refusal of permission will be foreseeable and you cannot invoke force majeure. If the plan is amended after the purchase, you may be able to rely on force majeure, but this is not automatic.
• Keep all documents: Keep a copy of the planning certificate, the local plan in force, the deed of purchase, and the decision refusing permission. In case of a dispute, these documents will be crucial to show that you acted in good faith.

This 1978 decision is part of a consistent line of Court of Cassation rulings. For example, in a judgment of 14 January 1975 (no. 73-14.567), the Court had already held that the purchaser could not invoke force majeure if the local plan predated the purchase, because he had the opportunity to consult it. More recently, in a judgment of 9 April 2015 (no. 14-16.789), the Court confirmed this principle: a change in regulations after the purchase may constitute a case of force majeure, but only if the change was unforeseeable and irresistible.

The trend of the courts is therefore strict: they require the purchaser to be diligent and to check the planning rules themselves. The tax authorities, for their part, are very meticulous about compliance with undertakings. With the digitalisation of local plans (notably via the Planning Geoportal), it is now easier to check before buying. But beware: online information may be incomplete. It is better to consult the town hall.

For the future, the ALUR law of 2014 strengthened the transparency of planning documents, but the principle remains the same: the purchaser is presumed to know the regulations in force. When in doubt, consult a lawyer lawyer or an urban planner before signing.

Key points to remember

FAQ:

1. Can I rely on a planning certificate to know if my land is buildable? Yes, but with caution. The planning certificate is an informative document that does not create definitive rights. It can be contradicted by the local plan. Always check the PLU.
2. What should I do if I could not build due to a refusal of permission? If the refusal is due to a local plan predating your purchase, you cannot invoke force majeure. You will have to pay the registration duties and possibly penalties. If the plan was amended after the purchase, you can challenge, but it will be difficult.
3. What are the deadlines for building? The deadline is four years from the deed of purchase. You must prove completion of the works (foundations, shell) within that period. In case of force majeure, the deadline may be extended, but this is rare.
4. Can I get a refund of duties if I was misled? Yes, if the seller or notary hid the existence of a restrictive local plan. You can hold them liable for fraudulent misrepresentation or breach of duty to advise. But you will have to prove their bad faith or negligence.
