The Cour de cassation recently issued an important advisory opinion on 8 October 2025 (reference: Cass. 1re civ., 8 oct. 2025, n° 25-70.016, Publié au bulletin) concerning the validity of acceleration clauses (clauses de déchéance du terme) in consumer credit agreements. This decision, stemming from a request for an advisory opinion submitted by the Tribunal judiciaire de Papeete (formerly the TGI Papeete), provides clarification on your rights if your lender attempts to demand immediate repayment of your entire loan for a reason other than payment default.
I. Background: The Question of Acceleration of Maturity
Acceleration of maturity (déchéance du terme) is the mechanism that allows the lender to demand immediate repayment of the entire outstanding principal before the originally scheduled date, if the borrower fails to meet a contractual obligation.
The question submitted to the Cour de cassation specifically concerned consumer credit agreements entered into from 1 May 2011 onwards (the effective date of loi n° 2010-737 du 1er juillet 2010):
« La clause contenue dans un contrat de crédit à la consommation prévoyant la déchéance du terme pour un motif autre que celui relatif à la défaillance de l’emprunteur dans ses remboursements est-elle, pour les contrats conclus à partir du 1er mai 2011, abusive et /ou illicite? Est-elle sanctionnée par son caractère réputé non écrit, par la déchéance du droit aux intérêts ou par les deux? ».
It is essential to understand that the 2010 reform abolished the standard-form contract templates (loi n° 2010-737 du 1er juillet 2010 portant réforme du crédit à la consommation), which raised the question of the legality of such clauses not provided for by law for grounds other than payment default. Prior to the entry into force of the 2010 law (i.e., before 1 May 2011), the former article L. 311-13 du code de la consommation required the preliminary credit offer to be drawn up in accordance with one of the standard-form templates established by the banking regulation committee. Before 2011, case law held that any modification of these mandatory terms imposed by the standard-form contract that worsened the borrower’s situation was unlawful and resulted in the sanction of forfeiture of the right to interest.
II. The Fundamental Distinction: Unlawfulness vs Unfair Terms
Furthermore, the advisory opinion of the Cour de cassation establishes an essential distinction for the borrower between the unlawful nature and the unfair nature of an acceleration clause.
1. The Non-Unlawful Nature (No Loss of Interest)
Since the reform of 1 July 2010 abolished these standard-form templates, the Court concludes that no specific statutory provision now prohibits acceleration clauses for causes other than failure to meet repayment instalments, rendering them not unlawful (even though they may still be unfair).
Consequence for the borrower:
- The clause is not classified as unlawful.
- It therefore does not trigger the sanction of forfeiture of the right to interest (i.e., the loss for the bank of the right to collect interest).
2. The Unfair Nature (Consumer Protection)
Conversely, even though the clause is not unlawful, it is liable to be declared unfair.
Pursuant to article L. 212-1 du code de la consommation, a clause is unfair if it creates, to the detriment of the consumer, a significant imbalance between the rights and obligations of the parties.
Consequence for the borrower:
- If the clause is found to be unfair, it is deemed unwritten. This means it is considered as having never existed in the contract.
III. The Assessment Criterion for Unfairness: The Essential Obligation
To determine whether an acceleration clause is unfair, the Cour de cassation refers to European case law (the Banco Primus judgment, CJEU, 26 January 2017).
The unfairness criterion is as follows:
The acceleration clause is unfair and deemed unwritten in particular where the right granted to the professional to declare the entire loan immediately due and payable does not depend on the consumer’s failure to perform an obligation which is of essential importance in the context of the contractual relationship in question.
It is for the court to assess whether such an obligation is essential.
Examples of clauses found to be unfair (non-essential):
Case law has already classified as unfair acceleration clauses based on circumstances external to the credit agreement in question, notably:
- Failure to repay another loan taken out by the borrower (1re Civ., 1er février 2005, pourvoi n° 01-16.733, Bull. 2005, I, n° 60);
- The resignation of the borrower-employee, in the case of a loan granted by the employer (1re Civ., 5 juin 2019, pourvoi n° 16-12.519).
Examples of potentially non-unfair clauses (essential):
The classification as unfair was rejected where the breach related to fundamental elements of the contract, such as:
- An inaccurate declaration by the borrowers concerning essential elements that determined the bank’s approval or that could jeopardise repayment (provided that the borrower retains access to a court), (1re Civ., 28 novembre 2018, pourvoi n° 17-21.625);
- The use of funds for a purpose other than that stipulated in the contract (provided that the clause does not deprive the borrower of the right to contest its application before a court), (1re Civ., 24 janvier 2024, pourvoi n° 22-12.222).
IV. Conclusion: Key Takeaways for Borrowers
The advisory opinion of 8 October 2025 provides the following answer to the question raised:
- Non-Unlawfulness: The acceleration clause triggered for a reason other than the borrower’s default is not unlawful and does not result in forfeiture of the right to interest for agreements entered into after 1 May 2011.
- Unfairness: Such a clause will be declared unfair and deemed unwritten if the lender’s decision to make the loan immediately due and payable is not based on the borrower’s failure to perform an essential obligation under the contract.
Your vigilance is required: If your lender invokes a ground for acceleration that has no direct connection with a fundamental breach of your loan obligations (such as payment default), you have a solid legal basis to challenge the unfairness of this clause and ask the court to deem it unwritten.
FAQ – Your Rights Regarding Acceleration of Maturity (Cour de cassation Advisory Opinion of 8 October 2025)
Is an acceleration clause triggered for a reason other than payment default considered unlawful?
No. The Cour de cassation is of the opinion that, for agreements entered into from 1 May 2011 onwards, such a clause is not unlawful. It justifies this on the grounds that no specific statutory provision now prohibits such clauses for causes other than failure to meet loan repayment instalments, following the abolition of standard-form templates by the 2010 law.
What is the consequence if the clause is not unlawful?
The fact that the clause is not classified as unlawful means that it does not trigger the sanction of forfeiture of the right to interest for the lender.
Can such a clause be challenged on other grounds?
Yes. Even though it is not unlawful, such a clause is liable to be declared unfair.
What makes a clause unfair?
Pursuant to article L. 212-1 du code de la consommation, a clause is unfair if its purpose or effect is to create, to the detriment of the consumer, a significant imbalance between the rights and obligations of the parties to the contract.
What is the key criterion used by the court to determine unfairness?
The essential criterion is that the acceleration clause is unfair in particular where the right granted to the professional to declare the entire loan immediately due and payable does not depend on the consumer’s failure to perform an obligation which is of essential importance in the context of the contractual relationship in question. It is for the court to assess whether such an obligation is essential. This criterion is based in particular on European case law (the Banco Primus judgment).
If a clause is found to be unfair, what is the sanction?
If the court declares the clause unfair, it is deemed unwritten. Being deemed unwritten means that the clause is considered as having never existed in the contract. The contract may continue without these unfair clauses, if it is possible to do so.
Are there examples of acceleration clauses that have been found unfair by the courts?
Yes, the Cour de cassation has already found unfair clauses providing for acceleration based on grounds that are external to the credit agreement in question. These include:
- Failure to repay another loan taken out by the borrower.
- The resignation of the borrower-employee, where the loan was granted by the employer.
Are there examples where an acceleration clause is considered not unfair?
Yes. The classification as unfair was rejected where the borrower’s breach related to obligations considered fundamental to the contract, such as:
- An inaccurate declaration by the borrowers concerning essential elements that determined the bank’s approval or that could jeopardise the repayment of the loan, provided that access to a court is not excluded.
- The use of funds for a purpose other than that stipulated in the contract, provided that the clause does not deprive the borrower of the ability to contest its application before a court.
