Background
Banque Populaire Méditerranée initiated real-property foreclosure proceedings against Mme [X] under two notarised loan agreements. On 16 January 2023 a payment-and-seizure order (commandement de payer valant saisie immobilière) was served on Mme [X] demanding €256,169.12, a figure that reflected acceleration of the entire outstanding loan balance following invocation of the loan’s acceleration clause (clause de déchéance du terme).
The enforcement judge (juge de l’exécution) issued an orientation judgment on 14 March 2024 annulling the payment-and-seizure order. The bank appealed. Before the Aix-en-Provence Court of Appeal, Mme [X] — for the first time — argued that the acceleration clause was an unfair term and therefore void. The bank responded in its final appellate submissions by conceding that the acceleration was irregular but asking the court to allow the foreclosure to continue on the basis of the installments that had actually fallen due and remained unpaid, rather than the accelerated full balance.
The Court of Appeal (5 December 2024) reversed the enforcement judge, validated the payment-and-seizure order, and fixed the bank’s recoverable claim at €65,285.39 (36 unpaid installments plus accrued interest of €3,587.51). Mme [X] brought a cassation appeal raising three grounds, contending principally that the bank’s request to reframe the claim on unpaid installments was a new claim raised after the orientation hearing and therefore inadmissible under Article R. 311-5 of the Code of Civil Enforcement Procedures.
The Court’s Holding
The Court of Cassation rejected all three grounds and dismissed the appeal. On the first and central ground, the Court applied Article R. 311-5 of the Code of Civil Enforcement Procedures, which bars any new challenge or incidental claim from being raised after the orientation hearing, on pain of automatic inadmissibility. The Court anchored its analysis in its own published Advisory Opinion of 11 July 2024 (n° 24-70.001), which held that when an enforcement judge treats an unfair clause as unwritten, the enforceable title loses its effect to the extent it relies on that clause, and the judge must recalculate the claim amount according to the applicable enforcement rules.
From this, the Court derived the following rule: where the debtor is the party who raises the unfair character of the acceleration clause — even for the first time on appeal from the orientation judgment — the creditor is admissible under Article R. 311-5 to file an incidental claim seeking to draw the consequences of that potential nullity on the quantum of its claim. The bank’s request to continue the foreclosure on the basis of genuinely unpaid installments was therefore not a “new claim” within the prohibition of Article R. 311-5; it was a response to a defence that the debtor herself introduced and that the court was in any event obliged to examine.
The Court confirmed that the Aix-en-Provence Court of Appeal had correctly applied this reasoning and had not violated Article R. 311-5. The remaining two grounds were dismissed without detailed reasons as manifestly incapable of producing cassation. Mme [X] was ordered to pay costs and €1,500 to the bank under Article 700 of the Code of Civil Procedure.
Key Takeaways
- A mortgage creditor who accepts that its acceleration clause is unfair may, on appeal from the orientation judgment, file an incidental claim to rebase the foreclosure on unpaid installments — this does not constitute a new claim barred by Article R. 311-5 CCPE.
- The trigger for this exception is the debtor’s own pleading: once the debtor raises the unfair-term defence (at any stage the court must examine it), the creditor’s responsive claim adjusting the claim amount is procedurally admissible.
- The ruling directly applies the Court of Cassation’s published Advisory Opinion of 11 July 2024 (n° 24-70.001), which requires enforcement judges to recalculate debt quantum when an unfair clause is deemed unwritten — confirming that that advisory opinion shapes both the substantive and procedural landscape of foreclosure litigation.
- Debtors who raise unfair-term defences strategically late in foreclosure proceedings should be aware that doing so simultaneously opens a procedural window for creditors to salvage their enforcement action on a reduced, but valid, basis.
Why It Matters
This decision resolves a tension that French mortgage foreclosure practice had left open since the July 2024 advisory opinion: could a bank, having lost the right to enforce a full accelerated balance because of an unfair acceleration clause, still recover unpaid installments within the same proceedings, or was it forced to start again? The Court of Cassation answers clearly in the affirmative, provided the debtor is the party who put the unfair-term issue on the table. This protects creditors from having an entire enforcement action collapse solely because a problematic boilerplate clause triggered the acceleration, while still giving debtors the benefit of the unfair-terms regime on the quantum of the debt.
For practitioners, the ruling underscores the interplay between consumer-protection law (unfair terms) and the strict post-orientation-hearing procedural cut-off that governs French foreclosure procedure. Lenders should audit acceleration clauses in notarised mortgage deeds proactively; borrowers and their counsel should factor in that raising an unfair-terms defence, while potentially reducing the debt, will not halt the foreclosure altogether if genuine arrears exist.
