Grounds for Nullity of a French Commercial Lease

A French commercial lease is null where it fails to satisfy the general conditions of contract validity under Article 1178 al. 1 of the Civil Code. Those conditions — consent, capacity, a determined object, and lawful content — are the foundation of every contract. When any one of them is absent or defective at the time of conclusion, the lease can be challenged.

Nullity may also arise from the failure to comply with specific statutory requirements applicable to commercial leases: rules governing capacity to grant or take a commercial lease, consent defects (error, fraud, duress), certain mandatory formal requirements, or the presence of clauses that are réputées non écrites (deemed unwritten) under commercial lease legislation. The invalidation of a single clause does not, however, automatically void the entire lease: the lease survives unless the impugned clause was a determining element of one or both parties' consent, or unless the parties themselves stipulated that the lease would be entirely void if a specific clause were struck (C. civ. Art. 1184; Cass. 3e civ. 24-6-1971).

Absolute Nullity vs. Relative Nullity: The Modern Distinction

The nature of the nullity — whether absolute or relative — determines who can raise it, whether it can be confirmed, and whether the sommation de se prononcer mechanism is available. The distinction is no longer governed by the presence or absence of an essential element of the contract (the classical theory), but by the nature of the interest protected by the rule that was violated (the modern theory, codified in Art. 1179).

Nullity is absolute where the violated rule protects the general interest. It is relative where the rule protects only a private interest. This distinction must be assessed rule by rule: where legislation or case law does not specify the character of the nullity, the court must determine whether the rule's purpose is the safeguard of a public interest or a purely private one (Cass. com. 22-3-2016 n° 14-14.218).

Absolute Nullity
Violates a rule protecting the general interest. Can be raised by any person with an interest, and by the public prosecutor. Cannot be confirmed — even by both parties acting together. The sommation de se prononcer is not available. No prescription defence extinguishes the underlying right.
Relative Nullity
Violates a rule protecting a private interest. Only the protected party may invoke it; the other party and third parties cannot. Can be confirmed (expressly or tacitly). Subject to 5-year prescription for the main action. The sommation de se prononcer is available once the defect has ceased.

The Sommation de Se Prononcer: Forcing the Issue

Since 1 October 2016, Article 1183 of the Civil Code provides a mechanism for the party who wants certainty about the lease's validity: they may formally require the party entitled to invoke a relative nullity to declare, within six months on pain of foreclosure, whether they confirm the lease or intend to pursue annulment. The demand must be in writing, set the six-month deadline, and state that silence will be treated as confirmation.

This mechanism is only available for relative nullity — it could not apply to absolute nullity, since that would in effect achieve a confirmation that the law forbids. It applies to all leases, including those concluded before 1 October 2016. A key prerequisite is that the cause of nullity must have ceased before the demand is made: the party who is still subject to the defect cannot yet confirm and therefore cannot meaningfully be summoned (Cass. 3e civ. 29-9-2016).

Practical advice: the sommation should be made by registered letter with acknowledgement of receipt to fix the start date of the six-month period precisely and to preserve pre-constituted proof of the demand.

Confirmation of a Lease Affected by Relative Nullity

A lease subject to relative nullity may be saved by confirmation. Confirmation is the act by which the party entitled to invoke the nullity renounces their right to do so. It is available only for relative nullity; a lease affected by absolute nullity cannot be confirmed by either or both parties (C. civ. Art. 1180 al. 2).

Confirmation is never presumed (Cass. 1e civ. 27-4-1953). It may be:

  • Express — a written act stating that the confirming party is aware of the defect, renounces the right to invoke it, and accepts the lease as valid (Art. 1182 al. 2 and 3).
  • Tacit — resulting from voluntary performance of the lease in full knowledge of the defect. This is the most frequent form in practice. Voluntary payment of rent or acceptance of the premises, once the confirming party is aware of the nullity ground, constitutes tacit confirmation (Cass. com. 8-1-2002; Cass. com. 21-4-2022; Cass. 3e civ. 23-11-2023). Knowledge at the time of performance is essential: a party who performs before discovering the defect does not thereby confirm.
  • By silence — where a sommation de se prononcer has been properly sent and the six-month period expires without the party acting in nullity, the lease is deemed confirmed (Art. 1183 al. 2).

Confirmation takes effect from the date of the confirming act. Between the parties, it is retroactive: the lease is treated as having been valid from the outset (Cass. com. 23-6-1981). Against third parties, however, confirmation is not retroactive: the lease is only enforceable against them from the date of confirmation. Where multiple parties are entitled to invoke a relative nullity — for example, multiple co-landlords — the confirmation of one does not prevent the others from pursuing the nullity (Art. 1181 al. 3).

💡
Confirmation vs. Remaking the Contract

Where the lease is affected by absolute nullity, the parties cannot confirm it — but they are not prevented from remaking the contract from scratch once the cause of nullity has disappeared, or from mutually agreeing to maintain the original terms if the defect no longer exists (Cass. 1e civ. 8-1-1985; Cass. soc. 25-6-1996). This distinction between confirmation and renewal of consent is practically significant where an original formal defect has been cured or a capacity issue has been resolved.

Amicable Annulment

The parties to a French commercial lease may, by mutual agreement, acknowledge the nullity of their lease and record it in a written instrument. Article 1178 al. 1 of the Civil Code, which is general in scope, permits this whether the nullity is absolute or relative. The agreement constitutes a contract in its own right: it requires valid consent and capacity, and a lawful, certain object. Although no writing is formally required for validity, a written record mentioning the cause of nullity is strongly advisable for evidentiary and publicity purposes. The agreed annulment produces exactly the same legal effects as a judicial annulment: retroactive erasure, restitutions, and potential damages claims.

Where the lease has a term of more than twelve years and has been published in the land registry, the amicable annulment instrument should also be published: the same logic that requires publication of judicial annulment demands applies.

Judicial Annulment: Procedure and Prescription

Who May Bring the Action

An action in absolute nullity may be brought by any person with a legitimate interest, and by the public prosecutor (Art. 1180 al. 1). An action in relative nullity may only be brought by the party the law specifically intends to protect (Art. 1181 al. 1). Neither the other contracting party nor third parties may invoke a relative nullity — this restriction applies with full force in the commercial lease context, including for defects such as vices du consentement (error, fraud, duress) where case law has consistently limited standing to the protected party.

The Five-Year Prescription Period

The right to bring an action in nullity based on the general law of contract prescribes in five years (C. civ. Art. 2224; C. com. Art. L110-4). The period runs from the day the claimant knew or ought to have known the cause of nullity. For vices du consentement, special starting point rules apply. The five-year period applies equally to absolute and relative nullity actions.

The Perpetual Exception of Nullity

The prescription of the main action in nullity does not extinguish the underlying right to invoke nullity as a defence. Article 1185 of the Civil Code provides that the exception of nullity — i.e., invoking nullity in response to a claim for performance of the lease — is perpetual, provided the lease has received no execution.

This is a powerful protection: even if the five-year period has expired, a party against whom performance of a never-executed lease is claimed may still raise nullity as a complete defence. The rule applies regardless of whether the nullity is absolute or relative (Cass. 1e civ. 24-4-2013; Cass. 3e civ. 16-3-2017). It applies whether the action for performance is a principal claim or a counterclaim (Cass. com. 15-11-2011).

⚠️
The Critical Execution Threshold

The perpetual exception is available only so long as the lease has received no execution. Any commencement of performance — even partial — extinguishes the perpetual character of the exception (Cass. com. 13-5-2014; Cass. com. 31-1-2017). Payment of rent by the tenant into the hands of the landlord or their agent constitutes execution and will deprive the tenant of the perpetual exception defence once the five-year action period has expired (Cass. 3e civ. 16-3-2017). The practical consequence: a party who suspects a nullity and has not yet performed must either act within five years or ensure they never pay rent under the contested lease.

Leases over Twelve Years: The Publication Requirement

Where the lease to be annulled has a term of more than twelve years and has been published in the land registry (as required for leases of that duration), the judicial demand for annulment must itself be published in the service de la publicité foncière (Décret 55-22 art. 28, 4°-c). This applies whether the demand is a principal claim or a counterclaim (Cass. 3e civ. 18-3-1998). Failure to publish renders the claim inadmissible — but this inadmissibility may only be raised by the parties to the lease, not by the court of its own motion (Cass. 3e civ. 7-11-2001). The defect can be regularised at any time before judgment (Cass. 3e civ. 22-6-2017), including by publishing the summons during the proceedings or by publishing a judgment at appeal stage. Decisions confirming or rejecting the nullity claim, and any withdrawal, must also be published.

Effects of Annulment: Retroactive Erasure

Annulment — whether judicial or amicable — produces its effects retroactively. The lease is treated as having never existed (C. civ. Art. 1178 al. 2; Cass. 1e civ. 16-7-1998; Cass. 3e civ. 2-10-2002). This retroactive erasure applies from the date of annulment and operates for both the future and the past. Every clause of the annulled lease is deprived of effect, including dédit clauses, penalty clauses, and unilateral options embedded in the lease — with the sole exception of arbitration clauses and jurisdiction clauses, which survive by reason of their legal autonomy (Cass. 2e civ. 4-4-2002; Cass. 1e civ. 8-7-2010).

Where the annulled lease had replaced a prior lease, the annulment causes the earlier lease to revive and continue by tacit renewal, absent any other instrument terminating it (Cass. 3e civ. 27-3-2002).

Restitutions: What Each Party Must Return

Landlord's Obligation to Return Rent and Other Sums

Because the annulled lease is deemed never to have existed, the parties must restore each other to the position they were in before the lease was concluded (C. civ. Art. 1178 al. 3). The landlord must return all rent and other sums received — including the security deposit (dépôt de garantie) — plus statutory interest. Interest runs from the date of each payment where the landlord acted in bad faith (for example, a landlord who committed fraud to obtain the lease); otherwise, interest runs only from the date of the nullity claim (Art. 1352-6 and 1352-7). Tax amounts paid to the landlord are included in the restitution (Art. 1352-6).

Tenant's Obligation: The Indemnité d'Occupation

The tenant cannot return in kind the enjoyment of the premises they received during the lease. They must therefore make restitution by equivalent, in the form of an indemnité d'occupation representing the value of the use they received (Cass. 3e civ. 10-5-2001; Cass. 3e civ. 24-6-2009). This indemnity is only payable if the landlord claims it (Cass. com. 4-3-2014).

The amount is assessed by reference to the value of the performance provided to the tenant, evaluated at the date it was provided (Art. 1352-8). It is not automatically equal to the contractual rent: where the premises were not in conformity with their intended use, courts have fixed the indemnity at a fraction of the rent. The contractually stipulated indemnity of occupation has no relevance, because all lease clauses are retroactively annulled along with the contract itself.

ℹ️
Exception: No Indemnité Where Nullity Not Attributable to the Tenant

Where the lease is annulled for a reason unrelated to the tenant's conduct and the premises were not compliant with their contractual destination, the tenant owes no indemnité d'occupation. The Cour de cassation confirmed this exception in a significant judgment of 3 November 2021 (Cass. 3e civ. 3-11-2021 n° 20-16.334): a tenant who obtained no genuine enjoyment of conforming premises cannot be required to pay an occupation indemnity where the annulment stems from the landlord's wrongdoing and the premises were non-compliant throughout.

The Fate of Guarantees and Interdependent Contracts

Guarantees Transfer to the Restitution Obligation

Securities and guarantees (sûretés) constituted for the performance of the annulled lease — most commonly a cautionnement (guarantee) — are automatically transferred to the restitution obligation arising from the annulment (C. civ. Art. 1352-9). This occurs by operation of law, without any need for a specific agreement or novation. The guarantor who undertook to secure the tenant's obligations under the lease therefore becomes liable for the tenant's obligation to pay the indemnité d'occupation and any other restitution obligation. This transfer applies only to the restitution obligation itself — not to any separate damages claim arising from the annulment.

Cascading Nullity of Interdependent Contracts

The annulment of a commercial lease may trigger the lapse (caducité) of other contracts that were concluded as part of the same overall transaction. Under Article 1186 al. 2 of the Civil Code, where two or more contracts are necessary for the realisation of the same operation, the disappearance of one may make performance of the other impossible or remove the determining condition of a party's consent to it. In that case, the other contract lapses — provided that the party against whom caducity is invoked was aware of the overall operation when they gave their consent (Art. 1186 al. 3).

In the commercial lease context, loan agreements taken out by the tenant to finance fit-out works have been held to lapse following annulment of the lease where the lease and the loans formed a single economic transaction (CA Rennes 9-9-2020). By contrast, a franchise agreement concluded five years after the lease, and capable of being performed in other premises, was held not to form part of the same operation as the lease (CA Paris 15-5-2019). The question is always whether the other contract was constitutively linked to the lease or merely incidental to it.

Annulling a French Commercial Lease: The Essentials
Grounds (C. civ. Art. 1178 al. 1): a lease is null when it fails to meet the conditions of contract validity (consent, capacity, determined object, lawful content). Nullity of a single clause does not void the entire lease unless that clause was a determining element of one or both parties' consent, or the parties stipulated total voidance.
Absolute nullity (C. civ. Art. 1179; Art. 1180): violates a rule protecting the general interest. Any person with an interest (including public prosecutor) may raise it. Cannot be confirmed even by both parties. Sommation de se prononcer not available.
Relative nullity (C. civ. Art. 1181): violates a rule protecting a private interest. Only the protected party may invoke it. Can be confirmed (expressly, tacitly, or by silence after sommation). Subject to 5-year prescription. Sommation de se prononcer available once the cause of nullity has ceased.
Sommation de se prononcer (C. civ. Art. 1183): forces the protected party to confirm or sue within 6 months or lose the right. Available since 1 October 2016 for all leases (including pre-2016). Relative nullity only. Requires the cause of nullity to have already ceased (Cass. 3e civ. 29-9-2016). Use registered letter with acknowledgement of receipt.
Confirmation (C. civ. Art. 1182): express (written act identifying defect and renunciation); tacit (voluntary performance in full knowledge of the defect — Cass. com. 8-1-2002; Cass. com. 21-4-2022; Cass. 3e civ. 23-11-2023); or by silence after sommation. Never presumed (Cass. 1e civ. 27-4-1953). Retroactive between parties but not against third parties. Multiple co-landlords: each must confirm independently (Art. 1181 al. 3).
Prescription (C. civ. Art. 2224; C. com. Art. L110-4): main action in nullity prescribes in 5 years from knowledge of the cause, for both absolute and relative nullity. Perpetual exception of nullity (Art. 1185): even after prescription, nullity may be raised as a complete defence to a performance claim — but only if the lease has received no execution at all. Even partial execution (including first rent payment) extinguishes the perpetual character (Cass. com. 13-5-2014; Cass. 3e civ. 16-3-2017).
Publication for leases over 12 years (Décret 55-22 art. 28, 4°-c): nullity demand must be published in the service de la publicité foncière; failure to publish = inadmissibility (raised by parties only, not the court). Defect regularisable before judgment. Decisions and withdrawals must also be published.
Retroactive erasure (C. civ. Art. 1178 al. 2): annulment operates retroactively — the lease is deemed never to have existed. All clauses are struck (including dédit, penalty, options) except arbitration/jurisdiction clauses (survive by legal autonomy). If the annulled lease replaced a prior lease, the earlier lease revives by tacit renewal (Cass. 3e civ. 27-3-2002).
Restitutions (C. civ. Art. 1178 al. 3; Art. 1352-6 to 1352-8): landlord returns all rent, charges, security deposit + statutory interest (from payment date if bad faith; from claim date if good faith; taxes included). Tenant owes indemnité d'occupation assessed at value of occupation actually received — not contractual rent. No indemnity owed if annulment unrelated to tenant's conduct and premises were non-compliant throughout (Cass. 3e civ. 3-11-2021 n° 20-16.334). Indemnity only payable if claimed by landlord.
Guarantees transfer to restitution obligation (C. civ. Art. 1352-9): securities constituted for performance of the annulled lease transfer automatically by operation of law to the restitution obligation. No agreement or novation required. Transfer covers the restitution obligation only — not separate damages claims. Interdependent contracts (Art. 1186 al. 2–3): annulment may trigger caducité of contracts forming part of the same overall operation, provided the other contracting party was aware of the overall operation when they consented.
