Expropriation: Compensation Fixed According to the Condition of the Property at the Date of the Order

Imagine: you are the owner of a plot of land in Firminy, in the Loire. You have obtained planning permission to build a block of 160 flats. You are about to start the works. But then the municipality announces an expropriation procedure for reasons of public utility. Your property dream collapses. And to cap it all, the compensation offered to you does not take into account the planning permission you obtained. Is this legal?

This is exactly the question that the Court of Cassation decided in 1973 in a famous case. An owner had acquired a plot of land within the urban area of Aix-en-Provence, with planning permission for 160 flats. The administration had initiated an expropriation, but the proposed compensation did not take the permission into account. The owner challenged this, and the Court of Cassation ruled in his favour.

This decision is a cornerstone of expropriation law: the compensation must be fixed according to the condition of the property at the date of the expropriation order, and not at an earlier date. In clear terms, if your property has increased in value between the time when the expropriation is envisaged and the date when the judge orders the transfer of ownership, this increase in value must be taken into account. A rule that can make a difference of several hundred thousand euros.

The Facts: An Everyday Story

In 1968, Mr X, a property developer, buys a plot of land in Aix-en-Provence. He quickly obtains planning permission for a development of 160 flats. But the municipality has other plans: it wants to expropriate the land to create a planned development zone. As early as 1967, the procedure is initiated. Mr X is informed of the imminent expropriation. He nevertheless continues his steps, obtains the permission, and incurs study costs.

In 1969, the prefect issues a vesting order, then the expropriation order is made in 1970. But in the meantime, the planning permission has been annulled by the administrative court, following a challenge by a third party. The administration then proposes compensation based on the value of the bare land, without the permission. Mr X refuses: he considers that the permission existed at the time of the expropriation order, and that the subsequent annulment should not operate to his detriment.

The case comes before the expropriation judge, then before the Court of Appeal of Aix-en-Provence, which rules in favour of the administration. Mr X appeals to the Court of Cassation. The Court of Cassation quashes the appeal judgment: it states that the compensation must be fixed according to the condition of the property at the date of the expropriation order. Now, at that date, the planning permission was still valid. The subsequent annulment could not retroactively reduce the compensation.

The Reasoning of the Court — Analysed

The Court of Cassation relies on Article L. 13-13 of the Expropriation Code (now codified in Article L. 321-1), which provides that the compensation is fixed according to the condition of the property at the date of the expropriation order. This principle is fundamental: it guarantees that the owner is not prejudiced by events subsequent to the decision that dispossesses him.

Why this date? Because it is the moment when the transfer of ownership is ordered. Before this date, the owner can still enjoy his property and increase its value. After it, he no longer has control over it. Case law has clarified that improvements made by the owner between the declaration of public utility and the order must be compensated, unless they are fraudulent or made solely for the purpose of increasing the compensation.

In this case, the planning permission had been obtained before the order, and it was valid. Even if it was annulled later, this does not call into question its existence at the key date. The judges therefore considered that the land had a higher value because of this permission, and that the compensation had to take this into account. A logical decision, but one that set a precedent.

Note that the Court of Cassation did not follow the administration's argument, which claimed that the permission had been obtained in fraud of the expropriating authority's rights. Indeed, the permission had been granted after the owner had been informed of the expropriation project, but this was not enough to qualify it as fraudulent. It was necessary to prove a deliberate intention to harm, which was not the case.

What This Changes for You — Concretely

If you are the owner of a property threatened with expropriation, this decision is your shield. It allows you to value all the improvements you have made to your property before the order: planning permission, works, fittings, etc. For example, in Rive-de-Gier, an owner who has obtained planning permission for an extension to his building before the order will see this increase in value taken into account in the compensation.

Let's take a concrete example: you own a bare plot of land valued at £100,000. You obtain planning permission for a house, which increases its value to £150,000. If the expropriation order is made while the permission is valid, the compensation must be £150,000, even if the permission is later annulled. That is the difference between fair compensation and spoliation.

For tenants, this decision has less direct impact, but it can influence the compensation due to the owner, and therefore the amount of rehousing. For co-owners, if the building is partially expropriated, the value of the common parts must be assessed at the date of the order.

If you are in this situation, you should:

• Keep all evidence of the value of your property at the date of the order (permissions, quotes, valuations).
• Not accept a compensation offer based on an earlier date.
• Challenge before the expropriation judge if the administration does not take into account increases in value.

Four Tips to Avoid This Type of Dispute

• Anticipate the reference date: As soon as you become aware of an expropriation project, have your property valued to fix its value at the date of the forthcoming order. Do not wait for the administration to impose its own.
• Document all improvements: Keep planning permissions, invoices for works, planning certificates. Any element that proves that your property has increased in value before the order is a legal weapon.
• Do not give in to haste: The administration may offer you compensation quickly, often less than what you deserve. Take the time to consult a specialised lawyer before accepting.
• Challenge abusive annulments: If your permission is annulled after the order, do not give up. Case law protects you, as in the 1973 case. Bring the matter before the judge to assert your rights.

Further Information: Related Case Law and Developments

This 1973 decision has been confirmed and clarified by several subsequent judgments. For example, the Court of Cassation ruled in 1985 (Civ. 3rd, 10 July 1985, No. 84-70.157) that improvements made to the property after the declaration of public utility but before the order must be compensated, unless they are fraudulent. In 1995, the Court added that fraud must be proved by the administration, not simply presumed (Civ. 3rd, 22 February 1995, No. 93-70.222).

The trend of the courts is therefore clear: to protect the owner against manoeuvres by the administration that would attempt to reduce the compensation by relying on an earlier date. However, beware: if you carry out works after the declaration of public utility solely for the purpose of increasing the compensation, without real necessity, you risk being faced with a finding of fraud. The line is sometimes thin.

For the future, this case law remains relevant. Development projects (ZACs, infrastructure, etc.) are multiplying, and owners must know their rights. The recent ELAN law (2018) did not modify this principle, which is an essential guarantee of the right to property.

Frequently Asked Questions

• What is the exact date to use for the valuation? The date of the expropriation order, i.e., the judge's decision that orders the transfer of ownership. It is this date that fixes the condition of the property.
• What should I do if my planning permission is annulled after the order? You can still claim compensation taking this permission into account, because it existed at the date of the order. The subsequent annulment has no retroactive effect on the compensation.
• Can I be compensated for works carried out after the declaration of public utility? Yes, provided they are before the order and not fraudulent. Example: renovation of a roof before the order will be taken into account.
• What are the time limits for challenging a compensation offer? You have two months from the notification of the offer to bring the matter before the expropriation judge. After this period, you lose this right.
• How much does an expropriation procedure cost? Lawyer's fees vary, but a first 30-minute consultation with Maître Zakine costs €45. Court costs are generally borne by the administration if you succeed.
