Condition Precedent of Signing a New Lease: Deemed Unwritten (Cass. civ. 3e, 22 Oct. 2015)

Imagine: you own a commercial property in Versailles, which you lease to a trader. The trader wishes to assign the lease to a buyer. In the assignment deed, a clause provides that the sale is conditional upon the signing of a new lease between the buyer and you, the lessor. But what happens if this new lease is never signed? Is the assignor free? Can the assignee force the signature? This seemingly technical question gave rise to an important decision by the Court of Cassation in 2015, which ruled: such a clause is deemed unwritten.

Why such severity? Because a condition precedent (a future and uncertain event on which the formation of the contract depends) must not relate to an essential element of the contract, otherwise it is considered potestative (i.e., dependent on the will of one party only). In this case, the signing of the new lease depends solely on the lessor's will, making the condition potestative on his part. The Court of Cassation therefore applied Article 1168 of the Civil Code (old), which provides that an obligation is conditional when it depends on a future and uncertain event, and considered that the clause was contrary to the very essence of the assignment contract.

But concretely, what does this decision mean for you? If you are an assignor, you cannot be indefinitely bound by a condition you do not control. If you are an assignee, you must be vigilant: any clause that subordinates the assignment to a new agreement with the lessor may be void. Let's delve into the details.

The Facts: A Story as Common as They Come

Mr. X, owner of a commercial property in Montreuil, had leased a unit to a company operating a shop. In 2011, that company wished to assign its lease to a buyer, Mr. Y. The assignment deed, signed on 15 March 2011, contained a particular condition precedent: "This assignment is subject to the fulfilment of the condition precedent of the signing of a new lease between the assignee and the lessor, under usual market conditions." In other words, the assignment would only become final if Mr. X, the lessor, agreed to sign a new lease with Mr. Y.

However, Mr. X refused to sign this new lease, considering that the proposed terms were not satisfactory. The condition precedent was therefore not fulfilled. The assignor (the company) then sued Mr. X to have the assignment declared void and to obtain damages. The Paris High Court ruled in favour of the assignor, but the Paris Court of Appeal reversed this judgment, holding that the clause was valid and that the assignment was void for non-fulfilment of the condition.

The case went up to the Court of Cassation, which quashed the appeal decision in 2015. The supreme judges held that the disputed clause related to an essential element of the lease assignment contract, namely the transfer of the lease to the assignee. Indeed, the signing of a new lease is an act that depends solely on the lessor's will, making the condition potestative on his part. Now, a potestative condition is void under Article 1174 of the Civil Code (old). The Court therefore decided that the clause should be deemed unwritten, meaning it is considered never to have existed. Consequently, the assignment was perfected upon the signing of the deed, without waiting for the fulfilment of the condition.

The Reasoning of the Court — Analysed

To understand this decision, one must first grasp the concept of a condition precedent. A condition precedent is a future and uncertain event on which the birth of an obligation depends. For example, in a property sale, obtaining a loan is a common condition precedent: if the loan is not obtained, the sale is cancelled. But this condition must not be potestative, i.e., it must not depend solely on the will of one party. Article 1174 of the Civil Code (old, now Article 1304-2) provides that any obligation contracted under a potestative condition on the part of the one who binds himself is void.

In this case, the condition precedent was the signing of a new lease between the assignee and the lessor. However, this signing depends solely on the lessor's will. The lessor can freely accept or refuse to sign. Thus, the fulfilment of the condition is entirely subject to the lessor's will, making it potestative. The Court of Cassation therefore held that the clause was void because it related to an essential element of the lease assignment contract. Indeed, the very purpose of the assignment is to transfer the lease to the assignee. If the assignment is conditional upon the conclusion of a new lease, this amounts to emptying the contract of its substance, because the assignee acquires no rights if the lessor refuses.

The Court relied on Article 1168 of the Civil Code (old), which defines a condition as a modality affecting an existing legal relationship. Here, the existing legal relationship was the initial lease, which was to be transferred. By subordinating this transfer to a new lease, the condition related to an essential element, which is prohibited. The judges also considered that this clause was contrary to public policy protecting the assignor, who should not be indefinitely bound by a condition he does not control.

This decision confirms previous case law: conditions precedent that depend solely on the lessor's will are void. It is therefore not a reversal but a strict application of principles. The lessor's arguments (Mr. X) were that the clause was freely negotiated and that the assignor had accepted the risk. But the Court held that freedom of contract cannot go so far as to create a potestative condition that destroys the principal obligation.

What This Changes for You — Concretely

This decision has major practical implications for all players in commercial property.

For the assignor (leaseholder): You are now protected. If you assign your lease and the deed contains a condition precedent of signing a new lease with the lessor, this clause is deemed unwritten. In other words, the assignment is perfected upon signature, and you cannot be held liable if the condition is not fulfilled. Example: in Versailles, a trader assigns his lease to a buyer. The lessor refuses to sign a new lease. Thanks to this decision, the assignment remains valid, and the assignor has already received the price. However, note: if the assignor guaranteed the fulfilment of the condition, he could be sued by the assignee for non-performance.

For the assignee (buyer): You must be extremely cautious. If you sign an assignment deed containing such a clause, you may find yourself without recourse if the lessor refuses to sign. Indeed, the clause being deemed unwritten, the assignment is perfected, but you have no lease with the lessor. You are therefore in a precarious situation, because the initial lease continues with the assignor, but you are not a tenant. undefined, I have come across cases where buyers had to negotiate a new lease under pressure, or lost their investment. Concrete example: in Montreuil, an entrepreneur paid €50,000 for a lease, but the lessor refused to sign a new lease. The clause being void, he lost his money and could not operate the premises.

For the lessor: You cannot use this clause to block an assignment. If you want to control the buyer, you must use other mechanisms, such as a right of approval or a non-assignment clause. However, you cannot subordinate the assignment to your own will to sign a new lease. If you refuse, the assignment will still take place, but you remain bound by the initial lease with the assignor, which can be inconvenient.

In summary, this decision clarifies the situation: the condition precedent of signing a new lease is void. If you are in this situation, you should check your assignment deed and, if such a clause is present, consult a lawyer to assess the consequences.

Four Tips to Avoid This Type of Dispute

• Tip 1: Remove any condition precedent of signing a new lease – If you draft an assignment deed, do not include a condition that depends on the lessor's will. Prefer an objective condition precedent, such as obtaining the lessor's approval under certain conditions, but without it being potestative.
• Tip 2: Include a clause for the lessor's approval of the assignee – The lessor may require a right of review over the buyer, but this must be framed: the refusal must be motivated by legitimate reasons (solvency, activity). An approval clause is valid if it does not confer a discretionary power on the lessor.
• Tip 3: Negotiate a new lease before the assignment – The assignee should ensure that the lessor agrees to a new lease before signing the assignment. Thus, the condition is fulfilled before signature, and there is no risk.
• Tip 4: Consult a lawyer lawyer before signing – A professional can detect dangerous clauses and advise on alternatives. The cost of a consultation is negligible compared to the financial stakes of an assignment.

Further Analysis: Related Case Law and Developments

This decision is part of a consistent line of case law. Already, in a judgment of 12 December 2001 (No. 99-21.371), the Court of Cassation had held that a condition precedent of signing a new lease was void because it made the assignment dependent on the lessor's sole will. The 2015 decision confirms this position, without notable evolution.

However, another judgment (Cass. civ. 3e, 16 June 2016, No. 15-13.254) accepted the validity of a condition precedent of lease renewal, because renewal is a right for the tenant, not a mere option for the lessor. The difference is subtle: in the case of renewal, the lessor is obliged to grant renewal unless there is a serious ground, so the condition is not potestative.

The trend of the courts is therefore to protect the assignor against potestative conditions, but also to preserve the lessor's rights when it comes to a real right (such as renewal). For the future, it is likely that such clauses will disappear from assignment deeds, as notaries and lawyers are now warned.

What You Must Absolutely Remember

FAQ:

• Q: Is a clause making the assignment conditional on signing a new lease valid?
  A: No, it is deemed unwritten (void) because it is potestative: it depends on the lessor's sole will.
• Q: What happens if such a clause appears in my assignment deed?
  A: The clause is ignored, and the assignment is perfected upon signature. But beware: the assignee has no lease with the lessor, which can be problematic.
• Q: As a lessor, can I impose the signing of a new lease to accept the assignment?
  A: Yes, but not in the form of a condition precedent. You can refuse the assignment under an approval clause, but you cannot subordinate the assignment to your own will.
• Q: What are the time limits to act if the condition is not fulfilled?
  A: You must act quickly, within 5 years from signature. But it is advisable to consult a lawyer as soon as the lessor's refusal is known.
• Q: Does this decision apply to all commercial leases?
  A: Yes, it is common law. It applies to all commercial leases, including those in Versailles, Montreuil, or elsewhere.
