A Post-2016 Duty That Changed Lease Negotiations in France

Prior to the civil law reform introduced by ordonnance 2016-131 of 10 February 2016, the pre-contractual duties of parties negotiating a French commercial lease were governed principally by case law. Courts had developed doctrines of réticence dolosive (fraudulent concealment) and culpable silence to impose liability on parties who withheld material information during negotiations, but the law was fragmented and its application unpredictable.

The 2016 reform enacted Article 1112-1 of the Civil Code: a standalone, statutory pre-contractual information duty applicable to all contract negotiations, including those for French commercial leases. The duty is mandatory and cannot be excluded or limited by agreement between the parties. It applies from the moment negotiations begin and continues until the lease is signed.

For landlords and tenants negotiating French commercial leases, the practical significance of Article 1112-1 is considerable. It imposes an affirmative obligation of disclosure — not merely a prohibition on lying — and it creates a specific regime of pre-contractual liability that operates independently of, but alongside, the law on consent vitiation by fraud or error.

📋
The Statutory Text — Article 1112-1 C. civ.

A party that knows information whose importance is determinative of the other party's consent must disclose it, provided that the other party legitimately does not know it or trusts the first party. The duty cannot be contractually excluded. It does not extend to an estimation of the value of the performance — meaning neither party is required to share their assessment of the fair rent. Breach is sanctioned by extra-contractual liability and, where the failure to disclose amounts to a vice du consentement, by nullity of the lease.

Who Owes the Pre-Contractual Information Duty in a French Commercial Lease?

The duty under Article 1112-1 is mutual: it rests equally on the landlord and the prospective tenant. In the commercial lease context, both parties are presumed to be sophisticated actors, but the asymmetry of knowledge between them — which differs depending on who knows what — is the operative trigger for the duty.

The Landlord's Disclosure Obligations

The landlord typically holds material information about the physical and legal condition of the premises that the prospective tenant cannot easily verify independently: the existence of hidden defects, the state of the building's co-ownership rules (règlement de copropriété), planning restrictions affecting the permitted use, pending administrative proceedings, asbestos or contamination issues, and the commercial lease history of the property. The professional presumption of knowledge attached to a landlord means they will rarely escape liability by claiming ignorance of such matters.

The Tenant's Disclosure Obligations

The tenant's duty is less frequently litigated but equally real. A prospective tenant who knows facts material to the landlord's decision to let — such as being subject to insolvency proceedings, holding a competing lease that would create a conflict, or planning to conduct activities incompatible with the building's co-ownership rules — is under a duty to disclose. The 2016 reform reversed pre-existing case law that had held insolvency proceedings were not required to be disclosed in the absence of a specific statutory text.

Important Distinction: Information vs. Advice

The pre-contractual duty under Article 1112-1 is a duty to inform — to reveal a datum — not a duty to advise or to make a recommendation. A landlord who correctly describes the planning status of the premises has fulfilled the information duty even if the tenant would have benefited from advice about whether the permitted use suits their business. The duty to advise is a higher obligation, generally associated with notaries and specialist advisers, not with the parties themselves. Conflating the two leads to inflated claims that courts consistently reject.

What Information Must Be Disclosed: The Determinative Importance Test

The duty does not extend to all information one party holds. Article 1112-1 al. 1 limits the obligation to information whose importance is déterminante for the other party's consent. Two categories of information satisfy this test.

Information Linked to the Lease Itself

Information is determinative when it has a direct and necessary link with the content of the commercial lease being negotiated. This encompasses anything that bears on the leased premises themselves — their condition, their regulatory status, their history, any encumbrances or restrictions affecting their use. Courts have found the duty extends to information about neighbourhood factors known to the landlord that would materially affect the tenant's decision (such as planned construction works adjacent to the premises that the landlord knew of but did not disclose). The party claiming breach must prove that the information was useful for the purpose of the contract and had a direct link to its content (Cass. com. 5-4-2016; CA Versailles 4-11-2021).

Information Linked to the Quality of the Parties

Information is also determinative when it relates to the capacity of the disclosing party to perform their obligations under the lease. A landlord who is subject to insolvency proceedings at the time of negotiating the lease, a co-ownership building whose general assembly has voted to demolish part of the premises, or a tenant company whose group parent (guaranteeing the lease) is known internally to be on the verge of filing for receivership — all of these involve information about the quality of the party that is likely determinative of the other side's consent to enter the lease on the terms proposed.

⚠️
Insolvency: A Pre-2016 Gap Now Closed

Before Article 1112-1 came into force, French courts had consistently held that a party was not required to disclose that it was the subject of a redressement judiciaire, since no statutory text imposed such a duty (Cass. com. 24-9-2003; CA Paris 30-1-2008). The 2016 reform reversed this. A party in insolvency proceedings that is actively negotiating a commercial lease without disclosing its financial situation is now at serious risk of pre-contractual liability — and potentially of having the lease annulled for dol par réticence if the concealment is deliberate.

Note the important exception: a party that benefits from a confidential mandat ad hoc or conciliation procedure is not required to disclose it, as these proceedings are expressly subject to a statutory duty of confidentiality (C. com. Art. L 611-15).

The Rent Estimation Exception

Article 1112-1 al. 2 contains a critical carve-out that is particularly significant in the French commercial lease context: the duty does not extend to an estimation of the value of the performance. In plain terms, neither the landlord nor the tenant is required to disclose their internal assessment of what the premises are worth, what a fair rent would be, or what comparable leases in the market have achieved.

This exception is deliberate and important. It preserves the adversarial dynamic of rent negotiation: the landlord who has been offered a higher rent by another prospective tenant has no obligation to disclose this, and the tenant who has identified comparable premises at a significantly lower rent is equally free to keep that information to themselves. The duty to inform does not transform commercial negotiations into a cooperative exercise in sharing valuation intelligence.

The rent exception does not, however, extend to factual information about the property that bears on its value but is not itself a valuation — such as the fact that the premises are subject to a planning blight, that a major tenant of the building has just given notice to vacate, or that the landlord has received expert advice indicating that the building's structure requires major works within the next five years. These are disclosable facts, not protected valuations.

Who Can Invoke the Duty: Legitimate Ignorance and Legitimate Trust

The duty is owed only to the party who légitimement (legitimately) does not know the relevant information, or who legitimately trusts the other party. A party that possessed the means to discover the information and chose not to investigate cannot generally claim to have legitimately ignored it. A large retailer negotiating a premium lease with specialist advisers, who could readily have commissioned a survey or reviewed planning records, faces a high bar in claiming that it legitimately ignored information about the premises that was discoverable with reasonable diligence.

The "legitimate trust" limb protects the party who, reasonably relying on the expertise or representations of the other side, did not feel the need to conduct independent enquiries. This is most likely to arise where there is a significant power and information imbalance — a first-time tenant dealing with an experienced institutional landlord and their specialist lawyers, for example. Courts assess the profile of the parties, their relative commercial sophistication, and the nature of their negotiating relationship in determining whether trust was legitimate.

💡
Practical Consequence: The Duty Shifts the Investigation Burden

A key consequence of the 2016 duty is that the party holding material information cannot subsequently argue that the other party should have investigated and found it themselves. The Cour de cassation has confirmed that a party who owed the duty cannot reproach the creditor of that duty for failing to conduct investigations to compensate for the absence of spontaneous disclosure (Cass. 3e Civ. 10-9-2013 n° 12-22.844, confirming the principle applicable under the new regime). This is a departure from the classical approach, under which ignorance was at the claimant's own risk if investigation was possible.

Proof: Who Bears What Burden

Article 1112-1 al. 4 allocates the burden of proof in a distinctive way. The party claiming that the duty was owed bears the burden of proving that the information was determinative and that it legitimately did not know it. Once that burden is discharged, the burden shifts: the party alleged to have breached the duty must prove that it actually provided the information.

Proof of the existence and performance of the information duty may be made by any means (C. civ. Art. 1358), since this is a matter of fact rather than the proof of a legal act. Written records of negotiations — emails, letter exchanges, term sheets, due diligence reports — are therefore highly relevant. In practice, landlords who have provided written disclosure documents (whether in a formal data room or simply by attaching the relevant technical diagnoses to the heads of terms) are well placed to demonstrate compliance.

Sanctions for Breach: Two Parallel Regimes

Breach of the pre-contractual information duty under Article 1112-1 triggers two parallel mechanisms, which are legally distinct and independently available to the injured party.

Extra-Contractual Damages (Art. 1112-1 al. 6)

The primary sanction is an action in extra-contractual liability (responsabilité extracontractuelle). The breach occurred before the lease was concluded, even if the claim is brought after signature. French courts limit recoverable damages to the perte de chance of not contracting or of contracting on different terms — not the full benefit of the bargain. The claimant who can show they would not have taken the lease had they known cannot claim all profits foregone; they can only claim the chance of avoiding the loss, which the court quantifies as a fraction of the total damage suffered. The quantification must be precisely pleaded — imprecise claims are dismissed even where breach is established (Cass. com. 21-6-2017 n° 15-17.059).

Nullity of the Lease (Art. 1112-1 al. 6 + Art. 1130)

Where the failure to disclose amounts to a vice du consentement — most commonly, dol par réticence (fraudulent concealment) — the French commercial lease can be annulled. This requires establishing that the concealed information was determinative of consent: the party would not have signed the lease, or would have signed on materially different terms, had it known the truth. Annulment and a claim for extra-contractual damages are legally independent: a party may pursue both, or bring a damages claim even after abandoning or losing an annulment action (Cass. 3e civ. 11-1-2012).

The Perte de Chance Quantification Trap

The limitation of recoverable damages to perte de chance is perhaps the most important practical consequence of the extra-contractual characterisation of pre-contractual liability. A tenant who took premises that turned out to be unsuitable for their business because the landlord withheld information about a planning restriction cannot recover their full business losses. They can recover only the assessed probability that they would have avoided those losses had they received the information. Courts frequently quantify this at a fraction of the total damage claimed.

This limitation is compounded by the requirement that the claimant must precisely identify the lost chance. A court cannot award damages for perte de chance without specifying the favourable outcome of which the claimant was deprived (Cass. com. 21-6-2017 n° 15-17.059). Imprecise pleading on this point leads to dismissal of the damages claim even where the breach of the information duty is established.

Overlap with Fraud (Dol) and the Annulment Regime

The pre-contractual information duty under Article 1112-1 operates in close proximity to the law of dol (fraud) in Article 1137 of the Civil Code. Dol par réticence — fraudulent concealment — occurs when one party deliberately withholds information with the intention of misleading the other into contracting. It is a ground for nullity of the French commercial lease and also gives rise to extra-contractual damages. Where the withheld information could have led the deceived party not to contract, or to contract on materially different terms, the lease can be annulled and the concealing party held liable for the full consequences of the nullity.

The difference between Article 1112-1 breach and dol par réticence lies in intent. Article 1112-1 does not require deliberate deception: a party can breach the information duty through negligent omission. Dol requires intentional fraudulent conduct. In practice, courts frequently find that a professional party — an institutional landlord, a commercial property developer — who withheld information that they clearly possessed satisfies the intentionality requirement for dol, since the presumption of knowledge attached to professional status makes it difficult to credibly claim innocent ignorance.

⚠️
Classic Scenario: The Copropriété Conflict

One of the most litigated applications of pre-contractual disclosure in French commercial leases involves premises in co-owned buildings. Where the règlement de copropriété prohibits the commercial activity for which the tenant is taking the premises, and the landlord knew or should have known of the restriction but did not disclose it, courts have consistently found both a breach of the pre-contractual information duty and dol par réticence. The lease is annulled, and the landlord (and any notary who authenticated the deed without verifying the co-ownership rules) is held jointly liable for the tenant's wasted expenditure — including fitting-out costs, rent paid in advance, and security deposits (CA Paris 28-6-1994). This scenario is particularly dangerous for international investors acquiring French commercial premises from sellers who do not always volunteer co-ownership complications.

Practical Guidance for Parties to French Commercial Lease Negotiations

Landlords negotiating French commercial leases should conduct a structured pre-disclosure review before entering substantive negotiations: verify the co-ownership rules, check planning permissions against the proposed permitted use, ensure technical diagnoses are current and complete, and consider whether any pending matters — litigation, administrative proceedings, planned major works — are material to a reasonable tenant's decision. Disclosing early protects against both liability and the risk of lease annulment at a later stage.

Tenants, particularly those coming from common law systems where the principle of caveat emptor gives the buyer (or tenant) primary responsibility for investigation, should understand that French law expects them to benefit from the information duty rather than to investigate everything themselves. Where the landlord has not disclosed material information that would have been readily available to them, the tenant is not penalised for failing to discover it independently. However, a sophisticated tenant with experienced advisers who could easily have found the information faces a higher bar in establishing légitime ignorance.

The French Commercial Lease Pre-Contractual Information Duty: The Essentials
Statutory basis (C. civ. Art. 1112-1; Ord. 2016-131): mandatory pre-contractual information duty in force since 1 October 2016. Mutual: applies equally to landlord and tenant. Cannot be excluded or limited by contract. Applies from the start of negotiations until signature.
Scope — determinative information only: the duty covers information whose importance is déterminante for the other party's consent and has a direct and necessary link to the lease content (premises condition, regulatory status, history, encumbrances) or to the quality of the party (capacity to perform, insolvency, guarantor financial position). Proof of determinative character is on the claimant.
Rent estimation exception (Art. 1112-1 al. 2): neither party must disclose their internal assessment of the fair rent or comparable market evidence. This preserves the adversarial dynamic of rent negotiation. The exception does not cover factual information that bears on value but is not itself a valuation (planning blight, major departing tenant, structural works known to landlord).
Insolvency — pre-2016 gap now closed: the 2016 reform reversed prior case law (Cass. com. 24-9-2003) — parties in insolvency proceedings must now disclose. Exception: confidential mandat ad hoc or conciliation procedures are exempt by statutory confidentiality (C. com. Art. L 611-15).
Legitimate ignorance / legitimate trust: the duty is owed only to the party who legitimately did not know the information or legitimately trusted the disclosing party. Sophisticated parties with investigation capacity face a higher bar. The party holding the information cannot shift blame to the other for failing to investigate (Cass. 3e Civ. 10-9-2013 n° 12-22.844).
Burden of proof (Art. 1112-1 al. 4): claimant proves information was determinative and legitimately unknown; burden then shifts to alleged breaching party to prove the information was actually provided. Proof by any means (Art. 1358). Written disclosure records (data room, diagnoses attached to heads of terms) are the most reliable evidence of compliance.
Dual sanctions (Art. 1112-1 al. 6): (1) extra-contractual damages limited to perte de chance — loss of chance of not contracting or contracting on different terms; must be precisely pleaded (Cass. com. 21-6-2017 n° 15-17.059); (2) nullity of the lease where failure to disclose amounts to dol par réticence (C. civ. Art. 1137). Both actions are legally independent and may be pursued simultaneously.
Copropriété conflict — most litigated scenario: landlord fails to disclose that the règlement de copropriété prohibits the tenant's intended use → breach of Art. 1112-1 + dol par réticence → lease annulled + landlord and notary jointly liable for tenant's wasted expenditure (fitting-out, advance rent, security deposit — CA Paris 28-6-1994).
