Imagine you own a commercial premises on the Croisette in Cannes. You have signed a lease with a luxury trader, with a clause guaranteeing a minimum rent, even if the market falls. You sleep soundly, thinking your income is secured. But then, after a few years, your tenant challenges this rent, considering it too high compared to the actual rental value. What to do?
This situation is not uncommon in our region, where commercial rents can vary significantly depending on location and economic conditions. In Le Cannet, as in Cannes, many landlords and traders ask this question: is a minimum rent clause really enforceable? Can one prevent a tenant from requesting a rent reduction before a judge?
The Cour de cassation answered these questions clearly in a decision of 30 March 2017. This case law (the body of judicial decisions that carry authority) serves as a reminder of the limits of contractual freedom in commercial leases. It protects tenants against excessive rents, even when they have signed a clause committing them. But what exactly does this change for you, landlord or trader?
The facts: a story as happens every day
The story begins with Mr. Dubois, owner of a commercial premises in the town centre of Le Cannet. In 2010, he leases his premises to the company Wathever, a business specialising in the sale of beauty products. The commercial lease (rental contract for professional activity) provides for an initial rent of €2,500 per month, with an index-linked clause (mechanism allowing automatic rent increases based on an index, such as the INSEE construction cost index).
But the clause that will change everything is this one: "The rent may never be judicially revised to an amount lower than the contractual rent, even if the rental value (the market price for a similar premises) proves to be lower." In short, Mr. Dubois thought he had secured his income: whatever happens, his tenant would pay at least €2,500.
The years pass, and the commercial property market in the region experiences fluctuations. In 2014, the company Wathever estimates that the rental value of its premises is now only €2,000. It therefore requests a judicial revision of the rent (procedure allowing a judge to adjust the rent in case of imbalance), to bring it down to this amount. Mr. Dubois refuses, relying on the minimum rent clause.
The dispute goes up to the tribunal, then to the court of appeal. The appeal judges rule in favour of Mr. Dubois, considering the clause valid. The company Wathever does not give up and seizes the Cour de cassation, the highest French judicial court. It is there that the fate of this clause will be decided.
The court's reasoning — dissected
The Cour de cassation, in its judgment of 30 March 2017, quashes (annuls) the decision of the court of appeal. Its reasoning rests on two essential legal pillars. First, it recalls the mandatory provisions (rules that cannot be derogated from by contract) of the commercial lease statute, notably Article L. 145-39 of the Commercial Code.
This article provides that, in a commercial lease, the tenant may request a judicial revision of the rent every three years, if the rent has increased by more than a quarter through the operation of the index-linked clause. In other words, the law protects the tenant against excessive increases. But the Court goes further: it considers that a clause that obstructs any downward revision, for the entire duration of the lease, is contrary to this protective spirit.
Next, the Court develops a subtle analysis on when a tenant can waive their right to revision. It explains: "The waiver by the lessee (tenant) of their right to obtain judicial revision can only validly occur once this right has been acquired." Translation: you cannot waive a right that you do not yet have. In the case of a commercial lease, the right to revision only exists after noting an increase of more than a quarter. Signing a clause from the conclusion of the lease, which blocks any future downward revision, is like waiving a right that is not yet born. It is therefore invalid.
The Court rejects Mr. Dubois's arguments, which invoked contractual freedom. It considers that this freedom stops where the legal protection of tenants begins. This is not a major evolution of case law, but rather a firm confirmation of already established principles. However, be careful: this does not mean that all minimum rent clauses are void. Only those that completely and permanently prevent downward revision are targeted.
What this changes for you — concretely
If you are a landlord in Cannes or in the jurisdiction of Grasse, this decision concerns you directly. Let's take an example: you lease a 100 m² premises on Rue d'Antibes in Cannes, with a rent of €5,000 and a similar minimum rent clause. If the rental value falls to €4,000, your tenant can now request a judicial revision to align the rent with the market. You will not be able to oppose this by invoking the clause.
Concretely, this means that your rental income is no longer guaranteed for life. You must anticipate that, in case of a market downturn, you might have to accept a rent reduction. undefined, I have encountered cases where landlords, confident in their clause, refused any negotiation, only to ultimately lose before the judge and have to repay overpayments (sums paid in excess) over several years.
If you are a commercial tenant, this decision is good news. It protects you against rents that become disproportionate. Imagine you pay €3,000 for a premises in Le Cannet, while similar premises are rented at €2,200. You can seize the commercial court to request a revision. The judge will then set a fair rent, based on the actual rental value. Timeframes? Count several months of proceedings, and legal fees that can vary, but often between €1,500 and €3,000.
For purchasers of commercial properties, always check the existing leases. A minimum rent clause may seem an asset, but it is fragile. If you buy a building with such a lease, know that the tenant could challenge the rent, thus reducing the profitability of your investment. What few people know is that this can also affect the sale value (selling price) of the property.
Four tips to avoid this type of dispute
- Draft precise and balanced clauses: Avoid overly broad formulas like "no downward revision." Instead, provide revision mechanisms based on objective indices, with reasonable ceilings and floors.
- Regularly assess the rental value: Every two or three years, request a professional estimate of the market rent for your premises. This allows you to adjust the rent amicably, without going through the judge.
- Negotiate amicably before seizing the courts: If you are a tenant and consider the rent too high, propose a renegotiation to the landlord. Mediation (conflict resolution process with a neutral third party) can often avoid costly litigation.
- Consult a specialised lawyer before signing: A commercial lease is a commitment for at least 9 years. Have the contract reviewed by a professional who knows recent case law, like that of 2017.

Deep dive: related case law and developments
The 2017 decision fits into a coherent line of case law. Already in 2011, the Cour de cassation had invalidated a similar clause in judgment No. 10-20.052, recalling that the commercial lease statute has a public policy character (set of fundamental rules that apply to all).
On the other hand, there are divergent decisions on more technical points, such as the validity of minimum rent clauses in specific contexts (for example, when the tenant is a large chain with strong negotiating power). But the trend of the tribunals is clear: they increasingly protect tenants against contractual imbalances.
For the future, this means that landlords will have to be more cautious in drafting their leases. Clauses too favourable to the landlord risk being systematically challenged. How to react? By adopting a more collaborative approach, where the rent is regularly adjusted according to the market, rather than fixed by rigid mechanisms.
In practice: what to do
Here is a checklist to guide you:
- If you have signed a lease with a minimum rent clause: Check if it is drafted in a way that blocks any downward revision. If yes, know that it is probably invalid. You can consider legal action to have it annulled.
- If you are in the process of negotiation: Insist that the lease provides for a triennial revision based on rental value, with a clear mechanism. Avoid absolute mentions like "never less than."
- If you notice a rent imbalance: Gather evidence (estimates, comparable leases) and address an amicable request to the landlord. In case of refusal, consult a lawyer to seize the commercial court.
- If you are buying a leased property: Have the leases analysed by an expert. A minimum rent clause can hide a litigation risk. Negotiate the price accordingly.
