Assigning a French Commercial Lease: What You Are Actually Transferring

The Legal Nature of a French Commercial Lease Assignment

When a French commercial tenant assigns its lease, the operation in French law is a cession du droit au bail — literally, an assignment of the right to the lease. This is a specific legal concept that sits at the intersection of contract law and commercial property law. It is a contract by which the tenant (the cédant) transfers to a third party (the cessionnaire) its entire position under the lease. That position has two faces: on the credit side, the right to enjoy and occupy the premises, including the valuable statutory right to renewal; on the debit side, the obligation to pay rent and comply with every condition in the lease.

The assignment is therefore more than a simple transfer of a right. The Cour de cassation has characterised it as comprising both a cession of a receivable — the right of enjoyment — and a transfer of the obligations of the lease (Cass. soc. 12-11-1954 n° 691). The assignee does not merely step into the shoes of the outgoing tenant in a metaphorical sense; it becomes the new contractual party to the lease, subject to all its terms from the date the assignment takes effect against the landlord.

This dual nature explains why the legal formalities for assigning a commercial lease are more complex than for a simple transfer of a right. The consent of, or at least notification to, the other contracting party — the landlord — is essential to make the assignment effective in the landlord's eyes. A transaction concluded without the landlord's knowledge or without the proper formalities remains inopposable to the landlord: the landlord can continue treating the original tenant as its contractual counterpart.

The Decisive Distinction: Lease Assignment vs Sale of the Business

The most commercially consequential distinction in French commercial lease assignment law is between a cession isolée du droit au bail — a transfer of the lease right alone — and a cession de fonds de commerce — a sale of the business operating from the premises, of which the lease forms one element.

A fonds de commerce is a bundle of assets — both tangible and intangible — that together constitute a going commercial enterprise. The intangible elements include the trade name, signage, goodwill, customer relationships, and the lease right. The tangible elements include equipment, stock, and fixtures. The defining element, without which no fonds de commerce can exist, is the clientèle: the body of customers attached to the enterprise. The Cour de cassation has held repeatedly that clientele does not attach automatically to premises; it is created by the commercial activity of the operator (Cass. 3e Civ. 16-6-1981 n° 1107). When the operator leaves, the clientele may or may not follow the business to new premises — but the point is that it belongs to the business, not to the walls.

This distinction carries enormous practical weight. Article L 145-16 of the Code de commerce makes any clause prohibiting the tenant from assigning the lease in connection with a sale of its business automatically void — the prohibition is treated as if it were never written. But the same protection does not apply to an isolated lease assignment: the landlord's contractual restrictions remain fully enforceable where no fonds de commerce is being transferred.

The Clientèle Test: What Courts Actually Look For

Because the distinction between a lease assignment and a business sale turns on whether clientele was transferred, courts have developed a substantial body of case law defining what counts. The central question is whether, at the date of the transaction, an active, functioning clientele attached to a business existed and was transferred to the buyer along with the other elements of the enterprise.

A number of indicators have emerged from the case law. The outgoing tenant must have been commercially active from the premises at the date of the transaction: a tenant who had ceased trading, deregistered from the trade register, and was left with nothing but the lease right has no clientele to transfer. If no stock of goods was included in the transaction, if no business equipment was transferred, and if the buyer began a completely different type of activity from the moment of taking possession, these are powerful indicators that no genuine fonds de commerce was transferred. Conversely, where the buyer continued the same activity as the seller, acquired the trade name and signage, and took over the existing customer base, a genuine business sale is established even if the parties labelled the transaction a lease assignment.

The Cour de cassation has consistently held that the qualification given by the parties in their deed is irrelevant: the court will requalify the transaction according to its substance (C. proc. civ. Art. 12 al. 2). A deed titled "sale of business" that in reality transferred no clientele will be treated as an isolated lease assignment. A deed titled "assignment of lease right" that in reality transferred a going concern with its clientele will be treated as a business sale. The burden of proving the true nature of the transaction falls on the party who challenges the contractual label — in practice, most often the landlord seeking to enforce restriction clauses.

Disguised Transactions: When Parties Try to Reframe the Deal

The financial stakes of the distinction have always created an incentive to frame transactions strategically. A tenant wishing to assign its lease to a buyer who will operate a different business — and who fears the landlord will resist on the basis of a successor-in-commerce clause — may be tempted to present the transaction as a business sale to take advantage of Article L 145-16's protection. Conversely, a tenant seeking to dispose of a bare lease right may be tempted to dress it up as a business sale to avoid the mandatory publication and creditor-opposition procedure applicable to cessions de fonds de commerce.

Courts are alert to both types of disguise. For the first, the test is whether clientele genuinely existed and was transferred: if the tenant had no active business at the premises, or if the transaction plainly concerns only the lease right, the labelling as a business sale does not save it. For the second, the Cour de cassation has held that a deed explicitly excluding clientele from a purported business sale — on the grounds that it had already been transferred previously — was requalified as a lease assignment where the other indicators supported that conclusion.

Where the landlord succeeds in establishing that a purported business sale was in reality an isolated lease assignment, the consequences can be severe: the restriction clauses in the lease apply, and if those clauses required landlord consent that was not obtained, the assignment may be inopposable to the landlord or constitute a ground for lease termination.

Corporate Variants: Contributions, Transformations, and Share Deals

The assignment regime extends to certain corporate transactions that are economically equivalent to a direct assignment. The contribution of a lease right to a separate company entity (apport en société) is treated as an assignment, because the lease right moves from one legal person to another distinct legal person (Cass. 3e Civ. 2-2-1977; CA Toulouse 11-3-2020). The same logic applies to a partial asset contribution not governed by the merger regime.

However, a corporate transformation — converting a SNC to a SARL, for example — does not constitute an assignment: the legal entity remains continuous throughout. Similarly, a transfer of shares in the tenant company, even a complete change of ownership, does not constitute a lease assignment: the tenant company is still the same legal person after the share transfer. The lease contract is unchanged; only the ownership of the company holding it has moved.

This distinction between asset deals and share deals is commercially important. A buyer who acquires shares in a company that holds a commercially attractive lease avoids the landlord approval and formality requirements entirely. The trade-off is that the buyer also acquires all the company's historical liabilities. The landlord has no legal mechanism to object to a share transfer, though the lease may in principle contain provisions designed to address changes of control — which themselves must comply with the limits of Article L 145-16.
