Commercial Subletting: When the Landlord Can Refuse Without Reason

You are the owner of commercial premises in Lattes, and your tenant announces that he has sublet part of the space to a tradesman without asking for your opinion. What can you do? Does the law allow you to object, even if the subtenant is reliable? This seemingly ordinary question was decided by the French Court of Cassation in a judgment of 3 October 1973 (No. 72-12.418).

Subletting (the letting of the premises by the head tenant to a third party) is strictly regulated by the commercial lease regime (Decree of 30 September 1953). In principle, it is prohibited unless expressly authorised by the landlord. But what happens if the lease is old, or if the landlord has tolerated sublettings in the past? The Court of Cassation answers: the landlord may refuse a subletting, even without reason, provided it is not provided for in the lease. Analysis.

The Facts: An Everyday Story

Mr and Mrs X are owners of commercial premises in Montpellier, which they let to company Y. Without informing the owners, company Y sublets part of the premises to a third party, Mr Z. When the X couple discover the subletting, they sue their tenant to have the lease violation declared and seek termination (cancellation) of the contract.

The head tenant defends himself: he argues that the disputed subletting dates back to a time before the law of 30 June 1926 (which strengthened the prohibition of unauthorised sublettings), and that it was tolerated by the owners. Indeed, the Public Assistance authority, the previous owner, had expressly tolerated sublettings. But the X couple contest this: they claim that the subletting in question is recent and that they never gave their consent.

The Montpellier Commercial Court rules in favour of the owners. The tenant appeals. The Montpellier Court of Appeal upholds the judgment, finding that the evidence provided by the tenant does not demonstrate a continuity of subletting from a time before the 1926 law. The tenant then appeals to the Court of Cassation.

The Court's Reasoning — Analysed

The Court of Cassation (the highest French judicial court) is asked to verify whether the Court of Appeal correctly applied the law. The legal basis is Article 1717 of the Civil Code (which governs the right to sublet), combined with Article 1134 (now 1103) which establishes the principle of binding force of contracts.

The head tenant relies on the tolerance of the previous owner to justify the subletting. But the Court of Cassation rejects this argument. It recalls that subletting is only authorised if expressly provided for in the lease or if the landlord has given written consent. Mere tolerance, even prolonged, does not amount to authorisation. And above all, the current landlord is not bound by tolerances granted by predecessors: each landlord can freely decide what they authorise or not.

The Court therefore validates the reasoning of the Court of Appeal: the X couple did not have to justify their refusal. They could oppose the subletting without reason because the lease did not provide for it. This judgment confirms settled case law: the owner of commercial premises has a discretionary right of veto over any unauthorised subletting.

What This Means for You — Practically

For the landlord: you have the right to refuse any subletting, even if the subtenant is reliable and the rent is paid. An example: in Frontignan, a landlord refused the subletting of a 50 m² premises to a hairdresser, even though the head tenant (a restaurant) wanted to reduce costs. The refusal was held valid because the lease did not mention subletting. Consequence: the tenant must comply with the original contract or vacate the premises.

For the tenant: if you are considering subletting, you must check your lease. If no clause authorises it, you must obtain your landlord's written consent. Without this consent, you risk termination of the lease (loss of your business) and damages (compensation for the loss suffered by the landlord). Average damages: 3 to 6 months' rent, i.e., €5,000 to €15,000 for a small premises in Lattes.

For the subtenant: you are in a precarious situation. Even if you pay rent, the landlord can have you evicted without notice if the subletting is unlawful. Never sign a sublease without seeing the landlord's written consent.

Four Tips to Avoid This Type of Dispute

• Include a subletting clause in the lease: at the outset, provide whether subletting is authorised, partially or fully, and under what conditions (prior consent, rent sharing, etc.). This avoids any ambiguity.
• Require written authorisation: if you are a landlord and agree to a subletting, formalise it by a lease amendment or registered letter with acknowledgement of receipt. Oral tolerance is worthless before a court.
• Check the history of sublettings: if you buy an already let premises, ask the seller for a sworn statement specifying whether there have been any sublettings and whether they were authorised. You are not bound by the previous owner's tolerances.
• Act quickly in case of dispute: if you discover an unauthorised subletting, send a formal notice (registered letter) to your tenant to stop it within 15 days. Failing that, bring the matter to the judicial court. Proceedings take 6 to 12 months at first instance.

Further Reading: Related Case Law and Developments

The position of the Court of Cassation has been consistent since the judgment of 3 October 1973. A judgment of 8 February 1978 (No. 76-14.237) clarifies that the landlord may refuse subletting even if the tenant has a serious reason (e.g., financial difficulties). More recently, the Court of Cassation recalled in a judgment of 13 January 2021 (No. 19-21.456) that total subletting (of the whole premises) is prohibited unless a clause provides otherwise, as it deprives the lease of its substance.

The trend of the courts is therefore protective of the landlord's rights. However, a legislative development is under discussion: the "Green Industry" bill (2023) envisages relaxing subletting to promote local trade. Nothing has been adopted yet, but stay vigilant.

Key Points to Remember

• Subletting is prohibited by default: without an express clause in the lease or written consent of the landlord, it is unlawful.
• The landlord can refuse without reason: they do not have to justify their opposition, even if the subtenant is exemplary.
• The previous owner's tolerance does not bind you: you can revoke any implied authorisation at any time.
• Possible sanctions: termination of the lease, eviction of the subtenant, damages (3 to 6 months' rent).
