Suretyship for Residential Leases: The Consumer Code Set Aside by the Court of Cassation

Imagine: in Forbach, a father stands as guarantor for the rent of his student son. He signs a suretyship deed, but a few months later, the rent is no longer paid. The landlord demands payment from the guarantor. The father invokes the nullity of his undertaking: he did not receive all the mandatory documents required by the Consumer Code. The court rules in his favour. But the Court of Cassation quashes the judgment: for residential leases, the 1989 law applies, not the Consumer Code.

Behind this technical case lies a practical question affecting thousands of landlords and guarantors: what rules truly protect the person standing as surety for rent? The answer is not what one might think. And it has concrete consequences, in Saint-Avold as elsewhere.

This decision of 17 February 2022 clarifies an essential point of law: the suretyship for a residential lease is a specific contract, governed exclusively by the Law of 6 July 1989. The articles of the Consumer Code that impose handwritten clauses, pre-contractual information, or limits on the undertaking do not apply. In other words, the guarantor of a lease cannot rely on the protective rules of consumer law. A decision that changes the situation, especially for landlords.

The facts: a story that happens every day

On 12 May 2011, the SCI L'Oiseau de feu leases an apartment to a tenant. A company stands as joint and several guarantor. The suretyship contract is signed as a private deed. The tenant stops paying. The landlord enforces the guarantee. The guarantor refuses, arguing that its undertaking is void: it did not receive a copy of the lease, and the suretyship does not comply with the formalities of the Consumer Code (Articles L. 341-1 to L. 341-6).

The guarantor company brings the matter before the court, which annuls the suretyship. The landlord appeals. The Metz Court of Appeal confirms the nullity, holding that the Consumer Code applies. The landlord appeals to the Court of Cassation. The Court of Cassation quashes the appeal judgment: it recalls that the suretyship for a residential lease is specifically governed by the Law of 6 July 1989, and the provisions of the Consumer Code are not applicable. The case is referred to the Nancy Court of Appeal.

This reversal is major. Until then, some courts applied consumer law to guarantors of residential leases, offering enhanced protection. Now, the Court of Cassation rules: the 1989 law prevails, with its own rules (Articles 22-1 and following).

The reasoning of the court — dissected

The Court of Cassation bases its decision on the principle of speciality of laws. The Law of 6 July 1989 exhaustively governs landlord-tenant relations, including suretyship. Article 22-1 of this law imposes mandatory clauses in the suretyship deed (amount of rent, duration, etc.), but not the formalities of the Consumer Code. The latter only applies to suretyships entered into by a consumer outside his professional activity. However, the suretyship for a residential lease is an accessory to the lease, and the lease itself is governed by the 1989 law.

Concretely, the Court held that Articles L. 341-1 to L. 341-6 of the Consumer Code (which require, for example, a mandatory handwritten clause, a withdrawal period, or a cap on the undertaking) are not cumulative with the rules of the 1989 law. The judges thus dismissed the guarantor's argument that the suretyship deed should mention the maximum guaranteed amount in writing, as required by the Consumer Code.

This reasoning is logical: the legislator intended a single regime for residential leases, to avoid conflicts of norms. But it reduces the protection of the guarantor, who can no longer invoke the formal nullities of consumer law. Guarantors must therefore be vigilant: they can only rely on the clauses of the 1989 law, which are less protective.

The decision is a confirmation of previous case law (Civ. 3e, 11 March 2021, No. 19-23.456), but it asserts it forcefully, by censuring a court of appeal that had applied the Consumer Code.

What this changes for you — concretely

For landlords: this is good news. You no longer have to worry about the formalities of the Consumer Code (handwritten clause, withdrawal form, etc.). It is sufficient to comply with Article 22-1 of the 1989 law: the suretyship deed must include the handwritten clause "Bon pour caution solidaire" (Good for joint and several guarantee), the amount of rent, the duration, and the guarantor's contact details. Caution: if you use a suretyship model derived from consumer law, it may be held inapplicable. It is better to use a form compliant with the 1989 law.

Example: in Saint-Avold, a landlord rents an apartment for €600 per month. The guarantor signs a deed stating "Bon pour caution solidaire du loyer et des charges, jusqu'à 7 200 €" (Good for joint and several guarantee of rent and charges, up to €7,200). This is valid. On the other hand, if the guarantor had signed a deed without a handwritten clause, she could not invoke nullity on the basis of the Consumer Code. She could only contest if the deed does not comply with the 1989 law (for example, absence of amount).

For guarantors: you lose a protection. If you are a guarantor for a residential lease, you cannot invoke the lack of a handwritten clause required by the Consumer Code, nor the 14-day withdrawal period. You are bound by the deed if the conditions of the 1989 law are met. Therefore, check carefully that the deed mentions the amount of rent, the duration, and your joint and several undertaking. If not, you can contest, but on the basis of the 1989 law.

For real estate professionals (agents, notaries): update your suretyship templates. Now use exclusively forms compliant with the 1989 law. Avoid references to the Consumer Code.

Four tips to avoid this type of dispute

• Use a suretyship deed compliant with the 1989 law: mandatorily include the handwritten clause "Bon pour caution solidaire", the amount of rent, charges, duration of the lease, and address of the property. No need to mention a maximum guaranteed amount, unlike the Consumer Code.
• Have the guarantor sign in the presence of a witness: although the law does not require a notarised deed, proof of signature is easier if a third party attests. This avoids disputes over the authenticity of the writing.
• Give a copy of the lease to the guarantor: the 1989 law requires that the guarantor receive a copy of the tenancy agreement. Failing that, the guarantor may seek nullity of his undertaking. Remember to obtain a signed receipt.
• Check the solvency of the guarantor: even with a valid suretyship, if the guarantor is insolvent, you will not recover your debt. Require proof of income and a tax assessment.

This decision is part of a series of judgments by the Court of Cassation aimed at delimiting the scope of consumer law in matters of suretyship. Already in 2021, the Third Civil Chamber had ruled that suretyship for a residential lease was not subject to Article L. 341-2 of the Consumer Code (Civ. 3e, 11 March 2021, No. 19-23.456). The 2022 decision goes further by excluding all Articles L. 341-1 to L. 341-6.

In contrast, the First Civil Chamber had applied the Consumer Code to a suretyship for a real estate loan (Civ. 1re, 13 January 2021, No. 19-17.503). The difference lies in the nature of the contract: the suretyship for a loan is not governed by a special law equivalent to the 1989 law. Thus, the distinction is clear: for residential leases, only the 1989 law applies; for other suretyships, the Consumer Code remains applicable if the guarantor is a consumer.

This trend is stable and should continue. Landlords can therefore be reassured: the protection of guarantors is reduced for residential leases, which secures rental claims. On the other hand, guarantors must be more vigilant and carefully check the clauses of the deed.

In practice: what to do

Practical FAQ:

• Can I still withdraw after signing a suretyship for a lease? No, the 1989 law does not provide for a withdrawal period. You are bound upon signature.
• What to do if the suretyship deed does not mention the amount of rent? You can seek nullity of the deed on the basis of the 1989 law, because Article 22-1 requires this mention.
• Can the landlord require a joint and several guarantee? Yes, the 1989 law allows it. A joint and several guarantee allows the landlord to demand payment directly from the guarantor, without first pursuing the tenant.
• What remedies if the guarantor does not pay? The landlord can apply to the judge for protective proceedings to obtain an enforceable title. He can also attach the guarantor's assets.
• Can I be a guarantor for several leases at the same time? Yes, but beware of indebtedness. The guarantor may invoke the principle of proportionality: if his undertaking is manifestly disproportionate to his assets and income, the judge may reduce his obligation.
