You are the owner of a plot of land in Laxou, and suddenly the municipality announces a road project that will take part of your parcel. Compensation will be paid to you, but how much? And what if, in addition, you have to sell them the rest of the land because it becomes undevelopable? This is exactly what happened to an owner in Marquette-lez-Lille, and the Court of Cassation has ruled: the part of the land that is not expropriated but purchased in addition does not give entitlement to the reinstatement allowance (the sum that compensates for reinvestment costs). A decision worth examining.
But what exactly does this change? For the owner, the distinction between dispossession compensation (for the expropriated part) and the acquisition price (for the voluntarily purchased part) is crucial. The former is increased by a reinstatement allowance, the latter is not. This legal subtlety can represent thousands of euros.
This judgment of 22 September 2010 (No. 09-69.049) reminds that the expropriation judge must apply of his own motion the mandatory rules of the Expropriation Code. In other words, even if the parties agree on a global amount, the judge must break down the compensation in accordance with the law. Let us examine this in detail.
The facts: a story like many others
Imagine Mr X, owner of a 6,148 m² plot in Marquette-lez-Lille, in the Nord department. The municipality decides to carry out a development project and needs part of his land to build a road. The expropriation (the procedure by which the State compels an owner to transfer his property for reasons of public utility, subject to compensation) only concerns a partial taking: 6,148 m². But the rest of the plot becomes undevelopable or difficult to sell. The municipality then offers to acquire the entire plot, including the part not expropriated.
The expropriation judge is seized to fix the compensation. In his judgment, he fixes a global compensation of €2,994,000, i.e., €232.35/m², without distinguishing the expropriated part (subject to the expropriation procedure) from the part acquired by agreement (in addition). However, this distinction is fundamental: for the expropriated part, the owner is entitled to dispossession compensation comprising the land value, a reinstatement allowance (generally 10% to compensate for reinvestment costs) and possibly compensation for moral or commercial prejudice. For the part acquired in addition, it is a voluntary sale, which does not give entitlement to the reinstatement allowance.
The owner challenges the judgment before the Court of Cassation, arguing that the judge should have applied the mandatory rules of the Expropriation Code. The Court agrees with him: the judge must, on his own initiative, distinguish the two parts and fix two separate amounts. In this case, the Court of Appeal had upheld the first instance judgment, but the Court of Cassation quashes the decision and refers the case to another Court of Appeal.
The reasoning of the court — dissected
The reasoning of the Court of Cassation is based on Article L. 13-1 of the Expropriation Code (now codified in Article L. 321-1), which provides that the expropriation compensation must cover the entirety of the direct, material and certain prejudice caused by the expropriation. However, in the case of a partial taking, the owner may request a total takeover (i.e., that the expropriating authority buys the whole plot) if the remaining part is diminished in value or unusable. In such a case, the judge must fix two separate amounts of compensation: one for the expropriated part, with a reinstatement allowance; the other for the part acquired in addition, without a reinstatement allowance, as it is a sale price.
In other words, the judge cannot mix everything into a single calculation. The Court recalls that these provisions are mandatory: the judge must apply them even if the parties do not invoke them. In short, the owner cannot waive this distinction, and the expropriating authority cannot impose a global price that would improperly include a reinstatement allowance on the part not expropriated.
In this case, the Court of Appeal had upheld the judgment that fixed a global compensation including a reinstatement allowance on the entire sum, including the part acquired in addition. The Court of Cassation censures this approach: the part acquired in addition, not being subject to the expropriation procedure, cannot give rise to payment of a reinstatement allowance. It is a matter of principle: the reinstatement allowance compensates for the expropriated owner's reinvestment costs, but if the sale is voluntary, these costs are already included in the negotiated price.
What few people know is that the expropriation judge has an active role: he must verify that the compensation complies with the texts, even if the parties agree. undefined, I have encountered cases where owners accepted a global compensation without realizing they were losing rights. This decision protects them.
What this changes for you — concretely
If you are the owner of land or property subject to a partial expropriation, and the expropriating authority offers to acquire the rest of the land by agreement, you must be vigilant: the reinstatement allowance only applies to the expropriated part. For example, in Nancy, an owner of a 1,000 m² plot in a development zone sees 400 m² expropriated for a tram project. The value is €200/m². For the 400 m² expropriated, the compensation will be €80,000 + €8,000 reinstatement allowance (10%) = €88,000. For the remaining 600 m² that the city offers to buy, the price will be €120,000, without reinstatement allowance. That is a total of €208,000, not €220,000 if the allowance were calculated on the whole.
If you are a property professional, you must advise your clients on this distinction. A developer who acquires land partly by expropriation and partly by agreement must know that the judge breaks down the sums, which can impact the overall cost.
If you are a tenant, you are not directly concerned, but be aware that expropriation compensation may include compensation for the evicted tenant, which is also calculated according to specific rules.
However, note that if the taking is total from the outset (the whole plot is expropriated), the reinstatement allowance applies to the entirety. The subtlety arises from a partial taking followed by an amicable acquisition of the surplus.
Four tips to avoid this type of dispute
- Have your property valued by an independent expert as soon as the expropriation notice is received. Do not rely on the expropriating authority's offer. An expert can determine the open market value and the amount of the reinstatement allowance.
- Demand a clear breakdown of the compensation in any agreement or judgment. Ask that the amount be itemised: value of the expropriated part, reinstatement allowance, compensation for prejudice, and price of the part acquired in addition.
- Consult a solicitor specialising in property law before accepting a global offer. In Nancy, a solicitor can verify that the judge has properly complied with the mandatory rules. The cost of a consultation (€45 with Maître Zakine) is negligible compared to what you could lose.
- Never accept a reinstatement allowance calculated on the whole if part of the property is acquired by agreement. Insist on the distinction. If the expropriating authority refuses, apply to the expropriation judge.
Further reading: related case law and developments
This decision forms part of a consistent line of authority from the Court of Cassation. Already, in a judgment of 8 July 2009 (No. 08-16.020), the Court had recalled that the reinstatement allowance can only be granted for the expropriated part. More recently, in a judgment of 12 January 2017 (No. 15-26.563), it specified that the judge must, even of his own motion, distinguish the two amounts of compensation. The trend is therefore clear: judges are increasingly strict on the breakdown of sums.
For the future, this case law protects small owners against often more powerful expropriating authorities (local authorities, the State). It imposes total transparency in the calculation of compensation. If you are concerned, do not hesitate to invoke these decisions.
Key points to remember

- What are the time limits for action? You have 1 month to appeal a judgment of the expropriation judge, and 2 months for an appeal to the Court of Cassation. Do not delay.
- What if the expropriating authority refuses to break down the compensation? Apply to the expropriation judge. He is obliged to apply the mandatory rules, even if the parties agree.
- Does this decision apply everywhere? Yes, it is national law. Whether you are in Nancy, Laxou or elsewhere, the same rules apply.
