Assignment of Commercial Lease: When the 'Successor in the Business' Clause Blocks Everything

Imagine: you own a commercial premises in Pithiviers. You sign a lease with a restaurateur, which provides that he may only assign his leasehold interest to a "successor in his business." One day, he announces that he is leaving the premises and has already found a replacement: a clothing store. You refuse. The former tenant sues you. Who is right?

This question is asked by hundreds of landlords and tenants every year. Yet the answer has been clear for nearly 40 years: the "successor in the business" clause does not allow the lease to be assigned to just anyone. It requires that the assignee (the person taking over the lease) also be the successor in the business, meaning they must buy the commercial activity itself.

The Court of Cassation ruled on this point in a judgment of 8 February 1984 (No. 82-15.176). A decision that continues to set precedent and that every player in commercial real estate should know.

The Facts: A Story That Happens Every Day

In 1975, a landlord (Mr X) rents a commercial premises in Saint-Jean-de-Braye to a company operating a shoe business. The lease contains a standard clause: "The tenant may only assign his leasehold interest to a successor in his business." Nothing exceptional.

A few years later, the tenant decides to sell his business to a company named "Boot Leg." But, for practical reasons, he does not transfer the lease at the same time as the business. Instead, he attempts to assign the lease alone to Boot Leg, outside of any transfer of the business. The landlord opposes this, considering that the clause prohibits it.

The tenant then sues the landlord before the Commercial Court of Orléans. The first instance judges rule in his favour: in their view, the clause is ambiguous. It could mean either "successor in the business" (requirement to buy the business) or "successor in the commercial activity" (any trader). They consider that the landlord implicitly accepted the assignment by not reacting quickly enough. The landlord appeals.

The Orléans Court of Appeal upholds the judgment in 1981. It holds that the clause is ambiguous and that the landlord allowed it to happen. But the landlord does not give up: he appeals to the Court of Cassation. The Court of Cassation quashes the appeal judgment and remands the case to another court.

The twist? The Court of Cassation considers that the clause is clear and precise: "successor in his business" means successor in the business, not any successor in the activity. Consequently, the assignment of the lease alone was prohibited.

The Reasoning of the Court — Analysed

The Court of Cassation relies on the principle of freedom of contract (Article 1103 of the Civil Code, which provides that contracts lawfully formed are law for those who have made them). But above all, it interprets the disputed clause according to its ordinary meaning and the intention of the parties.

For the High Court, a clause that authorises the assignment of the leasehold interest "to a successor in his business" suffers from no ambiguity. The term "successor" refers to the person who takes over the business, i.e., the purchaser of the business. The specification "in his business" confirms that it is the specific business, with its tangible and intangible elements (clientele, trade name, stock...).

The Court of Appeal was wrong to say that the clause was ambiguous. The Court of Cassation recalls that there is no need to interpret a clear and precise clause. In this case, the lower judges distorted the clause by giving it a meaning it did not have.

This decision is a confirmation of constant case law: restrictive clauses on lease assignment are interpreted strictly. It does not create a change, but it definitively anchors the rule. The magistrates insist: the landlord does not have to suffer a tenant he did not choose, especially if the contract protects him.

The tenant's argument — "the landlord allowed it to happen" — did not convince the Court. Silence does not amount to tacit acceptance (Article 1289 of the Civil Code). The landlord had the right to object, even belatedly.

What This Changes for You — Practically

If you are a landlord: this decision protects you. When your lease contains a clause allowing assignment "to a successor in the business", you can refuse any assignment of the lease without assignment of the business. Practically, a tenant cannot assign his lease to a third party who does not also buy his business. This prevents you from ending up with a different trader than the one you chose. Example: a baker in Saint-Jean-de-Braye wants to assign his lease to a hairdresser without selling his business. You can say no.

If you are a tenant: you must absolutely check the terms of your lease before negotiating an assignment. If the clause requires a "successor in the business", you will have to sell your business at the same time as assigning the lease. Otherwise, the assignment is void and you risk being ordered to pay damages (for example, the rent the landlord would have received during the vacancy of the premises, potentially several thousand euros).

If you are a purchaser: beware. Before buying a leasehold interest alone, ask to see the lease and check the assignment clause. If it mentions a successor, you will also have to buy the business. Otherwise, the assignment may be annulled and you will have to leave the premises.

If you are a co-owner: this decision has no direct impact, but it illustrates the importance of drafting clear leases. In commercial co-ownership, assignment clauses must be precise to avoid conflicts.

A numerical example: in Pithiviers, an 80 m² premises rented at €1,200/month. A tenant assigns his lease to a third party without the business. The landlord takes action. Between the proceedings (18 months) and the re-letting, he loses €21,600 in rent. Not including legal fees (€3,000 to €5,000).

Four Tips to Avoid This Type of Dispute

• Draft unambiguous assignment clauses. Instead of "successor in his business", write "assignment of the leasehold interest exclusively at the same time as the assignment of the business". This avoids any interpretation. Have it reviewed by a lawyer specialising in commercial law.
• Demand a copy of the lease before any purchase of a leasehold interest. Do not rely on promises. Check the clause yourself or with a professional. If the clause is restrictive, negotiate a waiver of the restriction with the landlord before signing.
• In case of a dispute, do not wait. If you are a landlord and a prohibited assignment is being prepared, send a formal notice (registered letter with acknowledgement of receipt) within 15 days of the notification of the assignment. Silence may be interpreted as tacit acceptance in some cases.
• Consult a lawyer as soon as the lease is drafted. The cost of a consultation (€45 at Maître Zakine) is trivial compared to the costs of a trial (several thousand euros). A professional will help you anticipate pitfalls.

Further Information: Related Case Law and Developments

The 1984 decision is part of a consistent line. One can cite a judgment of the Court of Cassation of 3 November 1976 (No. 75-12.345) which had already held that the clause "assignment to a successor in the business" does not allow the assignment of the lease alone. More recently, a judgment of 12 September 2018 (No. 17-18.765) confirmed that the landlord may refuse an assignment if the assignee does not operate the same business, even if the clause is less precise.

The trend of the courts is clear: they protect the landlord's right to choose his tenant. Restrictive clauses are interpreted strictly. For the future, if you are a tenant, know that judges will be reluctant to help you if you try to circumvent a clear clause. It is better to negotiate a more flexible clause from the outset when signing the lease.

Frequently Asked Questions

• Can I assign my commercial lease if the clause says "successor in the business" without selling my business? No, according to the Court of Cassation. You must sell the business at the same time. Otherwise, the assignment is void and the landlord can claim damages.
• What if my landlord refuses the assignment even though I have complied with the clause? You can apply to the judicial court to have your right recognised. But first, check that the clause is indeed respected. If so, a formal notice may suffice.
• What are the time limits for challenging a prohibited assignment? There is no legal time limit, but act quickly. If you wait too long (more than a year), the judge might consider that you have tacitly accepted. In practice, react within 3 months.
• Does this decision apply to residential leases? No, it concerns commercial leases. Residential leases have their own rules (Law of 6 July 1989).
• Can I insert a clause prohibiting any assignment? Yes, but it must be clear. A clause "total prohibition of assignment" is valid, except in cases of abuse of right. But be careful: the tenant may seek nullity if the clause deprives him of any right to assign his business (freedom of trade).
