Indivisibility Clause in a Commercial Lease: Beware of Dividing the Premises After the Lease

Picture the scene: you are the owner of a commercial premises in Dax, on the pedestrian street. You have been renting this premises for years to a well-established brand. The original lease covered a set of two rooms, with a clause stating "these two rooms are indivisible for the purpose of renting." One day, you sell half of the premises to a neighbour. The lease expires, the tenant asks for a renewal from each of the two new owners. One of them refuses and wants a separate rent for his part only. What happens?

This seemingly trivial question gave rise to an important judgment of the Court of Cassation on 19 December 2012 (No. 11-21.340). The High Court ruled: the indivisibility clause survives the division, and no landlord can, alone, demand a divided rent. In other words, the lease remains a whole, even if the walls are now fragmented.

But what exactly does this change for you, owner or tenant in the Landes or elsewhere? Let's dive into the details.

The Facts: A Story Like Many Others

In Agen, a commercial company (SARL Bareyre) operated a business from premises located at No. 5 of a street, consisting of several rooms let under a single lease. The lease contained an indivisibility clause (a clause prohibiting the separate letting of the different parts of the premises). The lease lasted several years. Upon its expiry, the original owner sold the building to two separate purchasers, each becoming owner of a part of the premises (e.g., Mr. X for the shop front, Mrs. Y for the back shop).

The tenant, wishing to stay, sent a request for renewal of the lease to each of the two new owners. Neither objected in principle. But one of them then applied to the court to fix a separate rent for his part alone, arguing that the indivisibility clause was void since the premises were now divided in ownership.

The first instance court (Tribunal de Grande Instance of Agen) dismissed his claim, holding that the renewed lease took over the clauses of the old lease, including the indivisibility. The dissatisfied owner appealed (Court of Appeal of Agen), but the Court of Appeal confirmed: no separate rent. He then appealed to the Court of Cassation.

The Reasoning of the Court — Analysed

The Court of Cassation dismissed the appeal. Its reasoning rests on two pillars. First, it recalls the fundamental principle of commercial lease law: the renewed lease is a new lease, not a mere extension of the old one. This means that the parties are free to agree on new terms, but failing agreement, the renewed lease is granted "on the terms and conditions of the expired lease" (Article L. 145-9 of the Commercial Code). The indivisibility clause is one of those clauses.

Second, the Court specifies that the fact that the premises were divided into two separate properties after the expiry of the lease does not affect this clause. Why? Because the renewal request was made by the tenant to each of the landlords, and none objected. Therefore, the lease is renewed on the same terms for the whole premises. One landlord cannot unilaterally demand a divided rent. That would be contrary to the economy of the original contract.

Note, however: if the dissatisfied owner had refused the renewal, the situation would have been different. But in this case, he let it happen, then tried to backtrack. Too late.

What few people know is that the Court of Cassation here follows consistent case law: the indivisibility clause is a contractual easement (an obligation that attaches to the property) that survives division. It is a protection for the tenant, but also a constraint for owners.

What This Means for You — Practically

If you are a landlord-owner in Parentis-en-Born or elsewhere: are you planning to divide a rented premises? Beware! The indivisibility clause will follow you. If you sell a part, the new owner will have to bear the single lease. And you cannot, alone, demand a separate rent. For example, if the total rent was €1,200 per month, you cannot demand €600 for your part alone until the tenant agrees to modify the lease.

If you are a tenant: this decision protects you. You retain the unity of your business. You will not have to negotiate with several landlords for the same premises. But be careful: if you accept renewal with only one of the owners, you risk losing the benefit of the indivisibility.

If you are a purchaser of a divided premises: check the existence of an indivisibility clause in the current lease. You could be tied to another owner for property management. undefined, I have seen cases where purchasers discovered after the fact that they had to share decisions with a reluctant neighbour.

Example in Parentis-en-Born: a 100 m² commercial premises rented at €1,500/month with an indivisibility clause. The owner sells 50 m² to a third party. The lease is renewed. The new owner cannot demand €750 rent for his part. He will have to wait until the end of the new lease (9 years) to renegotiate, or obtain the agreement of the tenant and the other owner.

Four Tips to Avoid This Type of Dispute

• Before dividing a rented premises, re-read the lease: look for the words "indivisible", "single lot", or any clause prohibiting separate letting. If it exists, you cannot divide without the tenant's agreement or a lease amendment.
• Have a lease amendment drafted by a lawyer lawyer: if you want to remove the indivisibility clause, negotiate with the tenant. The amendment must be in writing and signed by all parties. The rent can then be set per part.
• In case of partial sale, inform the purchaser in writing: mention the existence of the lease and its clauses in the sale deed. Thus, the purchaser cannot claim ignorance of the indivisibility.
• If you are a tenant, insist on a single lease in case of division: upon renewal, send your request to each owner, but insist that the lease remains single. If refused, apply to the judicial court to have the renewal declared on the previous terms.

Further Analysis: Related Case Law and Developments

The Court of Cassation had already ruled on indivisibility in a judgment of 17 November 2004 (No. 02-18.644): it held that the indivisibility clause binds successive owners because it constitutes a real charge (an obligation attached to the property). The 2012 decision confirms and clarifies that even after division, the clause survives as long as the lease is renewed.

However, case law is more nuanced when the division occurs before the expiry of the lease. Some Courts of Appeal have held that if the landlord divides the premises during the lease with the tenant's consent, the indivisibility clause may be lifted. But without consent, it remains.

The current trend of the courts is to protect the tenant-occupier by maintaining the unity of the leased premises. This is good news for traders, but a thorn in the side of owners who wish to split up.

Checklist Before Acting

What to do if you are considering dividing a rented premises with an indivisibility clause:

1. Check the lease: is there an indivisibility clause? Yes → step 2. No → free.
2. Contact the tenant: ask for their written consent to remove the clause or divide the lease.
3. If consent: have a lawyer draft an amendment, sign it.
4. If no consent: abandon the division, or sell the entire premises as is.
5. If division has already taken place: consult a lawyer to assess options (renegotiation, legal action).
