Assignment of a Commercial Lease: The Clause Prohibiting Subletting Without Transfer of the Business

Imagine the scene: in Bray-Dunes, a small seaside resort in the Nord, Mr. Dupont, owner of a rental property, signed a commercial lease with a chemist. The contract is formal: no subletting, no assignment of leasehold rights, except to a successor carrying on the same profession. One day, the tenant decides to transfer his business to a company and assign his leasehold rights to it, without changing the permitted use of the premises. The new tenant is indeed a chemist, but the business has not been transferred, only the leasehold rights. The owner objects and seeks termination of the lease (cancellation of the contract for non-compliance).

The question every owner asks: does a clause authorising assignment to a successor chemist permit the assignment of the lease without the business? The answer from the Court of Cassation (the highest French judicial court) is an emphatic no. In its judgment of 28 April 1971, it quashes the decision of the lower courts which had validated the assignment, on the ground that they had distorted (misinterpreted the meaning of) clauses that were nevertheless clear and precise.

This decision, although old, remains an essential reference for any landlord or tenant faced with a restrictive assignment clause. It recalls a golden rule: when the contract is clear, judges cannot interpret it. And that changes everything for your rights.

The Facts: A Story That Happens Every Day

Mr. and Mrs. X, owners of a building in Gravelines (in the Nord, a few kilometres from Dunkirk), granted a commercial lease to a tenant operating a chemist's business. The contract, drafted in precise terms, stipulated: "The tenants may not sublet nor assign their rights under this lease, except to a successor chemist; if they wish to assign their business to a purchaser carrying on a different profession or trade, they must notify the landlord to obtain his consent."

A few years later, the tenant decides to transfer his business to another premises and assign his leasehold rights to a company (a legal person) which continues to operate a chemist's shop. The landlord, considering that this operation is prohibited by the contract, sues the tenant for termination of the lease and eviction.

The Court of Appeal (the second instance court) rules in favour of the tenant. It considers that the clause does not require the business to be assigned together with the lease: it suffices that the successor in the lease is a chemist and has not changed the permitted use of the premises. The landlord appeals to the Court of Cassation.

The Court of Cassation, in a brief but scathing judgment, censures the appeal judges for "distortion" (misrepresentation of the clear and precise meaning of a contract). It recalls that the agreement prohibits the assignment of the leasehold right except to a successor chemist, and that this exception is conditional upon the assignment of the business. In plain English (to be clear: the contract clearly states that assignment of the lease is only permitted if the business is also assigned).

The Reasoning of the Court — Analysed

To understand this decision, we must return to a fundamental principle of contract law: the prohibition on judges distorting clear and precise clauses of an agreement. This principle, now codified in Article 1192 of the Civil Code (the judge cannot, under the pretext of interpretation, add a condition that is not there), was already in force in 1971.

The disputed clause contained two parts:

• Principle prohibition: "The tenants may not sublet nor assign their rights under this lease, except to a successor chemist."
• Specific condition: "In the event of assignment of the business to a purchaser carrying on a different trade, notice to the landlord to obtain his consent."

The appeal judges had considered that the first part authorised any assignment of the lease to a chemist, without requiring the assignment of the business. The Court of Cassation tells them that this is an error: the only exception to the prohibition on assignment is the assignment to a "successor chemist", which necessarily implies the assignment of the business (the successor must take over the commercial activity, not just the premises).

In other words, the contract is clear: the assignment of the leasehold right is only authorised in favour of a successor in the business. One cannot "empty" the business of its activity and assign the lease to a company that would carry on the same activity but without having acquired the business. It is a matter of respecting the parties' intention: the landlord agreed to let to a chemist, not to just anyone operating a chemist's shop with no link to the original business.

This decision confirms settled case law: restrictive assignment clauses are to be strictly interpreted. If the landlord intended to prohibit the assignment of the lease without the business, he did so in clear terms, and the judge must defer.

What This Means for You — Practically

For the landlord: You can sleep soundly: if your lease contains a clause prohibiting assignment except to a successor in the business, you are entitled to refuse any assignment of the lease alone. Concrete example: in Gravelines, a landlord signed a lease with a hardware merchant. The tenant wants to assign his lease to a company that takes over the premises but not the stock or clientele. You can object and, if necessary, seek termination of the lease. However, be careful: the clause must be clear. If it is ambiguous, the judge may interpret it in favour of the tenant.

For the tenant: You must check the terms of your lease before assigning your rights. If the clause requires the assignment of the business, you cannot assign the lease without selling your clientele, stock, and trade name. An isolated assignment of the lease exposes you to an action for termination and damages (compensation) that could amount to several months' rent. For example, if your rent is €2,000 per month, the court could award €12,000 in damages.

For the potential assignee: Before signing an assignment of lease, check the contract clauses. If the seller assigns you the lease without the business, you risk being left without any right: the landlord can seek eviction. Insist on a warranty clause (a written promise that the seller will indemnify you in case of problems) and, if possible, have the assignment approved in writing by the landlord (an addendum to the lease).

In practice, disputes of this kind are common. In my experience, I have seen tenants who thought they could assign their lease "bare" (without business) to a family member, only to find themselves in court for breach of contract.

Four Tips to Avoid This Type of Dispute

• Draft unambiguous assignment clauses: If you are a landlord, specify in the lease that any assignment of the leasehold right is conditional upon the prior assignment of the business. Use phrases like "the tenant may assign his right under this lease only to a purchaser of the business, whether for consideration or gratuitously." Avoid vague terms like "successor" without further precision.
• Require written consent for any assignment: Even if the assignee is a successor chemist, ask them to provide an extract Kbis (official document attesting to the legal existence of the company) and proof of their status. Have an addendum to the lease signed to formalise the assignment.
• If you are a tenant, always inform the landlord in writing: Before any assignment, even partial, send a registered letter with acknowledgement of receipt to the landlord requesting their consent. Keep a copy. This protects you in case of later challenge.
• In case of doubt, consult a specialist lawyer: A poorly drafted clause can cost thousands of euros. A lawyer can check whether your proposed assignment complies with the lease and advise you on the procedure. The cost of a consultation (€45 for 30 minutes) is negligible compared to the risks.

Further Reading: Related Case Law and Developments

This 1971 decision is part of a consistent line of the Court of Cassation. As early as 1929, the Court held that "the clauses of a commercial lease must be interpreted strictly in favour of the landlord" (Civ. 20 February 1929). More recently, in a judgment of 10 July 2013 (No. 12-21.234), the Court reiterated that a clause prohibiting assignment of the lease except to a successor in the business prohibits any isolated assignment of the leasehold right, even if the assignee carries on the same activity.

The trend of the courts is therefore clear: protection of the contractual intention of the landlord. However, note that since the Pinel Law of 2014 (Law of 18 June 2014), commercial leases contain mandatory provisions, particularly on rent caps. But contractual freedom remains the rule for assignment clauses. Thus, a landlord may perfectly well prohibit any assignment, even with the business, provided this is expressly stated.

For the future, one can expect that judges will continue to sanction assignments of the lease without the business, especially if the landlord proves damage (loss of rent, change of activity, etc.).

Key Points to Remember

FAQ:

1. Q: Can I assign my commercial lease without assigning my business?
   A: It depends on your lease. If the contract requires the assignee to be a successor in the business, the answer is no. Otherwise, in the absence of a clause, assignment of the lease alone is possible, but it is risky.
2. Q: What if my landlord refuses the assignment?
   A: Check the reasons for the refusal. If the refusal is abusive (e.g., if the assignee is a successor chemist and the lease does not prohibit it), you can apply to the judicial court to have the validity of the assignment declared.
3. Q: What are the risks of an unauthorised assignment?
   A: The landlord can seek termination of the lease, eviction of the tenant, and damages. The amounts can reach several years' rent.
4. Q: Can I sublet part of my commercial premises?
   A: If your lease prohibits subletting, you cannot. Even if the contract is silent, subletting is prohibited except with the landlord's consent (Article L. 145-31 of the Commercial Code).
5. Q: Must a successor chemist necessarily buy the business?
   A: Yes, according to this decision. The status of "successor" implies a transfer of the business, not merely taking over the premises.
