Assignment of a Commercial Lease: Why You Cannot Assign Your Lease Without the Business

Imagine the scene: in Caussade, Tarn-et-Garonne, a trader decides to sell his business. He finds a buyer for his business (the set of movable assets and the clientele). But the commercial lease (the rental contract for the premises) is in the name of his wife, who does not operate the business herself. The landlord, owner of the walls, never gave his consent for the lease to be transferred to the buyer. Result? The buyer finds himself without a lease, and the sale falls through. This situation, experienced by hundreds of traders every year, raises a crucial question: can you assign a commercial lease without the landlord's consent?

The answer comes from a landmark ruling of the Court of Cassation of 7 February 1984 (No. 82-14.584). The judges laid down a clear principle: assignment of a commercial lease without the landlord's consent is only permitted if it is in favour of the purchaser of the business. In other words, you cannot 'sell' your lease to someone who does not also buy your activity and clientele. This principle, although logical, is often misunderstood, and non-compliance can lead to the nullity of the assignment and damages.

This ruling, although old, remains an absolute reference for all players in commercial property. It protects the landlord against abusive assignments, but it also offers security to the tenant who assigns his business: the buyer automatically obtains the right to the lease, without risk of refusal by the owner. In this article, I will dissect this decision, explain its reasoning, and give you practical tips to avoid pitfalls. Whether you are the owner of a commercial property in Montauban or a tenant in Caussade, these rules directly concern you.

The Facts: A Story Like Many Every Day

The case that gave rise to this ruling begins in Montauban, in a small shopping street. Mrs Y., owner of a building, granted a commercial lease to a tenant. The latter, after a few years, decides to assign his business to a buyer. But here's the thing: the lease was granted to a legal entity (a company) whose manager is different from the assignor of the business. At the time of the assignment, the assignor of the business and the assignor of the lease are not the same person. The landlord, Mrs Y., was not informed and did not give her consent. The buyer of the business therefore finds himself on the premises without any right to the lease.

Mrs Y. then sues the assignor and the buyer to have the assignment of the lease declared void for lack of her consent. She also claims damages for infringement of her rights. The commercial court of Montauban finds in her favour, but the defendants appeal. The Court of Appeal of Toulouse upholds the judgment, but the assignors appeal to the Court of Cassation.

Before the Court of Cassation, the assignors argue that the assignment of the lease was valid because it accompanied the assignment of the business. But the Court rejects their argument: it notes that the lease had been granted to a company distinct from the assignor of the business, and that the assignor of the business was not the holder of the lease. Consequently, the assignment of the lease could not be made without the landlord's consent. The Court quashes the appeal judgment on a procedural point, but confirms the principle: assignment of the lease without the business requires the landlord's consent.

The Reasoning of the Court — Dissected

The heart of the ruling is in one sentence: 'assignment of a commercial lease without the landlord's consent is only permitted if it is in favour of the purchaser of the business'. This principle stems from Article 1717 of the Civil Code (which provides that the lessee may assign his lease unless otherwise stipulated), but the Court of Cassation gives it a restrictive interpretation in commercial matters. Indeed, the status of commercial leases (decree of 30 September 1953, now codified in Articles L. 145-1 et seq. of the Commercial Code) aims to protect the business. The lease is an accessory to the business: it allows the activity to be carried on. If you sell the business, the lease automatically follows, because it is an essential element of the value of the business. On the other hand, if you sell the lease alone, without the business, you deprive the landlord of the guarantee that the new tenant will operate a similar business, and you risk devaluing his property.

The Court therefore distinguishes two situations: on the one hand, the assignment of the business (sale of the activity, clientele, equipment) automatically entails the assignment of the lease, without the need for the landlord's consent (unless the lease contains a clause to the contrary). On the other hand, the isolated assignment of the lease (without the business) is an operation that requires the express consent of the landlord. Otherwise, it is void and the assignor may be ordered to pay damages.

In this case, the problem was that the lease had been granted to a company, while the business belonged to an individual. The assignment of the business therefore did not entail the assignment of the lease, because the holders were different. The Court considered that the assignment of the lease without the business was a separate operation, subject to the landlord's consent. In the absence of consent, the assignment was void. This reasoning is a confirmation of previous case law, not a reversal. It is part of a logic of protecting the landlord against uncontrolled assignments.

What This Means for You — Concretely

If you are the owner of a commercial property (landlord), this decision is your shield. You have the right to control who occupies your walls. Now, if a tenant tries to assign his lease to a third party without asking for your consent, and without assigning his business, you can object and seek nullity of the assignment. For example, in Montauban, a landlord recently consulted me: his tenant, a restaurateur, wanted to assign his lease to a friend who was opening a clothing shop. The business (clientele, name, equipment) was not being assigned. Thanks to this case law, I was able to confirm that he could refuse, because it was an isolated assignment of the lease.

If you are a tenant (lessee) and you wish to sell your business, know that the lease will automatically follow. You do not need the landlord's consent for the assignment of the lease, provided that it is included in the sale of the business. On the other hand, if you simply want to 'pass on the lease' to a family member or an associate, without selling the activity, you must imperatively obtain the written consent of the landlord. Failing this, the assignment is void and you may have to compensate the landlord.

For the purchaser of a business, this case law is a security: you are certain to recover the lease without any possible challenge, provided that the assignment of the business is regular. But be careful: check that the assignor is indeed the holder of the lease. In the 1984 case, the assignor of the business was not the holder of the lease, which caused everything to fail. Before buying, ask to see the lease contract and make sure that the seller is indeed the tenant in title.

Four Tips to Avoid This Type of Dispute

• Check the concordance of titles: Before any assignment, ensure that the person assigning the business is also the holder of the lease. If the lease is in the name of a company and the business in the name of an associate, you must regularise the situation by modifying the lease or by first assigning the shares.
• Obtain written consent from the landlord: If you are assigning the lease without the business (for example, for a change of activity or for a relative), ask for the landlord's authorisation in writing. Keep proof of this consent (registered letter with acknowledgement of receipt or notarial deed).
• Draft a precise assignment deed: In the deed of assignment of the business, expressly mention that the lease is assigned in its entirety. This will avoid any ambiguity and will allow you to prove that the assignment of the lease is indeed linked to that of the business.
• Consult a solicitor before any operation: The rules are technical and the consequences of a mistake can be serious (nullity, damages, eviction). A solicitor specialising in property law, like me, can help you secure your transaction, whether you are in Caussade or Montauban.

Further Analysis: Related Case Law and Developments

The solution of 1984 has been constantly confirmed since. For example, the Court of Cassation ruled in 1993 (No. 91-15.247) that the assignment of a commercial lease to a third party who does not acquire the business is void, unless otherwise stipulated or the landlord agrees. More recently, in 2018 (No. 17-17.901), it specified that the landlord's refusal to consent to an isolated assignment of the lease may be abusive, but it is up to the tenant to prove this abuse. Thus, the trend is to maintain a balance: the landlord retains a right of scrutiny, but cannot arbitrarily oppose.

A notable development concerns approval clauses in leases. More and more commercial leases contain a clause stipulating that any assignment, even with the business, is subject to the landlord's consent. The Court of Cassation validates these clauses, provided they are not abusive (Cass. civ. 3e, 12 May 2016, No. 15-14.388). Consequently, it is crucial to read your lease contract carefully to know whether authorisation is necessary, even for an assignment included in the business.

For the future, we can expect the courts to continue to protect the landlord's right to choose his tenant, while sanctioning abusive refusals. If you are a tenant and your landlord systematically refuses any assignment, a judge could force him to do so under certain conditions.

In Practice: What to Do

• Before assigning your business: Check that the lease is in your name. If not, make an addendum to the lease to substitute yourself. Then, draft a deed of assignment of the business including the lease. Send a copy of the deed to the landlord by registered letter.
• If you want to assign only the lease: Ask for the landlord's written consent. If he refuses, you can try to negotiate or apply to the interim relief judge to have an abuse declared, but know that success is not guaranteed.
• If you are a purchaser of a business: Require the seller to show you the original lease and check that he is indeed the holder. Ask for a certificate from the landlord confirming that he has no objection to the assignment (if the lease so provides).
• If you are a landlord and a tenant notifies you of an assignment without your consent: React quickly. Send a reasoned refusal letter and, if necessary, sue the assignor and the assignee for nullity of the assignment before the judicial court. You can also claim damages if you suffer a loss.
