Fraud and Assignment of Commercial Lease: the French Supreme Court Protects the Subtenant

Imagine: you are in Saint-Cyprien, tenant of a cave converted into a restaurant for years. You have invested, hired staff, built up a loyal clientele. One day, without warning, a new face appears and says: 'Sorry, the lease has been assigned, you are a subtenant without title, you must leave.' What can you do? This is exactly the situation that the French Supreme Court decided in a judgment of 12 October 1971. And the answer is strong: if the assignment is fraudulent, the person who committed the fraud cannot hide behind a lack of formality.

This decision is a formidable weapon for subtenants who are victims of manoeuvres. It establishes a simple but powerful principle: fraud corrupts everything. Even the absence of registration of a deed cannot serve as a shield for someone who has orchestrated the spoliation. So, how did the judges reach this conclusion? And above all, how can you protect yourself?

I am Maître Cécile Zakine, a real estate lawyer, and I will tell you this story — that of the Clamouse cave — so that you know exactly where you stand if someone ever tries to dispossess you by deceit.

The facts: a story that happens every day

It all begins in 1963. The owners of the Clamouse cave, near Saint-Cyprien, grant a 50-year commercial lease to a certain Mr. Vila. He operates the site as a tourist attraction. But soon, Vila sublets the operation to a company, probably to relieve himself of management. So far, nothing illegal. Except that the owners, the X consortium, view this sublease unfavourably. Perhaps they wanted to regain control, or favour another operator?

On 15 May 1963, they enter into a new lease with another company, company Y, for the same land. Problem: Vila's initial lease is still in force, and his sublease as well. Company Y then claims to be the new head tenant and demands that the subtenant company vacate the premises. But the subtenant resists. It brings the matter to court, which rules in favour of the owners and company Y: the assignment of lease is valid, and the subtenant must leave.

The subtenant appeals. The Montpellier Court of Appeal, in a judgment of 16 December 1969, annuls the assignment of lease. Why? Because the assignment was fraudulently concluded between the head tenant (Vila) and the assignee (company Y), with the aim of dispossessing the subtenant. Company Y appeals to the Supreme Court, arguing that the assignment had not been registered and therefore could not be invoked against it. But the Supreme Court dismisses the appeal, in a landmark ruling that remains famous.

The reasoning of the court — explained

In its judgment of 12 October 1971, the Supreme Court confirms the Court of Appeal's decision. It states: 'Since the judges were able to consider that an assignment of lease had been fraudulently concluded between the head tenant and the assignee in order to dispossess the subtenant of the operation, the assignee is no longer entitled to invoke against the victim of his actions the lack of registration of his sublease right, fraud being an exception to all rules.'

Concretely, this means that when the assignment of lease is intended to harm a third party (here the subtenant), the assignee cannot rely on the rules of land registration (registration in the land register) to assert his right. Generally, an unregistered deed is unenforceable against third parties. But here, the assignee himself had participated in the fraud. And the maxim 'fraus omnia corrumpit' (fraud corrupts everything) prevails over formal rules.

This solution is neither a revolution nor a reversal. The Supreme Court applies a well-established principle: no one may benefit from his own wrongdoing. But it does so with particular force, sweeping aside the procedural argument of lack of registration. The lower courts had found that the assignment had been organised to oust the subtenant, without any legitimate consideration. The Supreme Court validates their analysis.

For owners, the judgment is a warning: attempting to circumvent the rights of a subtenant by a fraudulent assignment exposes them to having the assignment annulled, without being able to hide behind formalism.

What this means for you — practically

If you are a subtenant: this decision is your shield. You can challenge any assignment of lease that aims to evict you without legitimate reason. Even if the assignment is not registered, the assignee cannot invoke it against you if he acted fraudulently. Example: you run a bar in Prades, subleased for 10 years. The owner and a third party set up a scheme to replace you. You can seek nullity of the assignment before the tribunal judiciaire. However, the burden of proving fraud lies on you: you will need concrete evidence (correspondence, witness statements, suspicious chronology).

If you are a landlord owner: be cautious. Entering into a new lease with a third party while a lease is in force may be considered fraud if you seek to oust the subtenant. You risk nullity of the deed and damages. Remember to check for the existence of subleases before signing.

If you are an assignee (purchaser of the lease): do not participate in a dubious scheme. Even if the deed is registered, fraud can cause it to fall. Require guarantees from the assignor regarding the absence of disputed subleases.

Time limits for action vary: for an action for nullity on grounds of fraud, you have 5 years from the discovery of the fraud (Article 2224 of the Civil Code). The amounts at stake can be substantial: loss of business, lost investments, removal costs. In the cave case, the issue was the operation of a tourist site, worth several hundred thousand euros annually.

Four tips to avoid this type of dispute

• Register your sublease in the land register: even if not mandatory for all leases, registration protects you against fraudulent assignments. A registered deed is enforceable against third parties.
• Keep all evidence of your operation: rent receipts, maintenance invoices, correspondence. In case of dispute, you can demonstrate your peaceful and continuous occupation.
• If the head lease is assigned, demand to be informed: the head tenant must notify you of any assignment. Failure to do so may be an indication of fraud.
• Consult a lawyer at the first signs of tension: a proposed assignment, a notice to quit, a refusal to renew. Prompt action can block the fraud.

Further reading: related case law and developments

This decision is part of a consistent line of case law. Already in 1954 (Civ. 1re, 12 May 1954), the Supreme Court held that fraud renders a deed unenforceable even if it is formally regular. More recently, it has extended this principle to other areas: for example, in real estate sales, if the seller and buyer collude to defraud a creditor, the deed may be annulled (Civ. 3e, 15 June 2017, No. 16-18.765).

The tendency of the courts is therefore protective for victims of fraud. This means that even if formalities are complied with, a fraudulent scheme will be penalised. In the future, we can expect this solution to be applied even more rigorously, particularly in commercial leases where the economic stakes are high.

Frequently asked questions

1. What is a fraudulent assignment of lease?
It is an assignment concluded between the head tenant and a third party with the aim of harming a subtenant, for example to oust them without right.

2. Can I be evicted if the assignment is not registered?
Normally, an unregistered deed is not enforceable against you. But if the assignment is fraudulent, the assignee cannot even invoke this lack of registration to evict you.

3. How to prove fraud?
By any means: written exchanges, witness statements, suspicious chronology (assignment just after a renewal request for your sublease), abnormally low price, etc.

4. What time limits for action?
You have 5 years from the discovery of the fraud to seek nullity of the assignment. But act quickly: the longer you wait, the harder it becomes to prove.

5. What if I am a bona fide assignee?
If you purchased the lease without knowledge of the fraud, you may seek recourse against the assignor for warranty against eviction. But beware: your good faith may be questioned if you did not verify the rental situation.
