Acceleration of the debt (déchéance du terme): the formalities that determine immediate enforceability of the claim

For a lender, acceleration (déchéance du terme) is not a debt-recovery housekeeping step: it is the act that turns a claim payable at a future date into a claim that is due, and therefore open to enforcement. If wrongly declared, it does not produce the intended effect, and a creditor who believes it holds a claim that is due discovers, often at the stage of attachment or of a challenge to its admission in the insolvency proceedings, that it is pursuing enforcement of a sum that was not owed. The stakes are twofold: access to enforcement, which requires a claim that is certain, liquidated and due, and the creditor's position against guarantors and other creditors in insolvency proceedings (procédure collective). This guide follows the chronology of the declaration, the applicable statutory formalities, the particulars checked by the courts, and then the consequences of an irregular acceleration for recovery and for the filing of the claim.

What acceleration changes exactly in the claim

The starting point is Article 1305-2 of the French Civil Code: what is owed only at a future date cannot be demanded before it falls due. The time limit benefits the debtor; while it runs, the lender has no claim that is due on the outstanding principal, even if several instalments are unpaid. Instalments that have fallen due are, for their part, due by operation of law on their date.

Acceleration removes that benefit and makes the principal not yet due immediately payable. It may have a statutory or a contractual origin, a distinction that governs the applicable formalities.

Statutory acceleration results from specific provisions. Article 1305-4 provides that the debtor may not claim the benefit of the time limit if the debtor fails to provide the security promised to the creditor or reduces the security guaranteeing the obligation. Article 2344, paragraph 2, resulting from Ordinance No. 2021-1192 of 15 September 2021 reforming the law of security interests, adds that, for a non-possessory pledge, the creditor may rely on acceleration of the secured debt, or seek additional security, if the grantor fails in its duty of preservation. These cases are valuable in asset-backed financings, but they do not in themselves dispense with the formalities that the contract itself has set out: if the credit agreement makes any declaration of acceleration subject to a formal notice (mise en demeure) and a period for remedying the default, the creditor remains bound by its own stipulation.

Contractual acceleration, by far the most common, rests on the early repayment clause (exigibilité anticipée) of credit agreements, which lists the events of default: failure to pay an instalment, breach of a financial covenant, disposal of an asset, change of control, warning procedure. Litigation focuses on this clause, and it is its implementation, not its drafting, that is most often found wanting. The particular case of the financial covenant, the waiver and the renegotiation of the debt is dealt with in our article on breach of a bank covenant.

The formalities of the formal notice: the text, then the case-law practice

The forms of formal notice admitted by Article 1344

Since Ordinance No. 2016-131 of 10 February 2016 reforming the law of contract, the reference text is Article 1344 of the French Civil Code:

The debtor is put on notice to pay either by a summons or an instrument containing a sufficient demand, or, if the contract so provides, by the mere fact that the obligation has fallen due.

Two operational consequences follow. First, a summons by a commissaire de justice (bailiff) is not the only form admitted: an instrument containing a sufficient demand is enough, which opens the way to a registered letter with acknowledgement of receipt provided it is a formal demand and not a mere accounting reminder. Second, the provision validates the contractual dispensation from formal notice by the mere fact that the obligation has fallen due, provided the contract so provides. The former wording of Article 1139 of the Civil Code, prior to the reform, should no longer be used as a reference in letter templates.

The scope of this contractual dispensation must, however, be handled with caution. In consumer law, the control of unfair terms under Article L212-1 of the French Consumer Code, which penalises terms creating a significant imbalance to the detriment of the consumer, has led the national courts and the Court of Justice of the European Union to examine early repayment clauses that dispense the lender from any formal notice and any opportunity to remedy the default. Before relying on an acceleration clause operating "by operation of law and without formal notice", a lending institution should check the latest state of this case law and not take for granted the effectiveness of the stipulation in a contract concluded with a consumer.

The particulars expected in the prior formal notice

No text lists the particulars of the formal notice that precedes an acceleration. It is the courts that, over the course of credit litigation, have developed substantive requirements on which the effectiveness of the act depends. In practice, a formal notice is harder to challenge when it contains:

• precise identification of the contract concerned (date, number, amount of the facility);
• a statement of the sums fallen due and unpaid, drawn up as at a certain date, distinguishing principal, interest and ancillary amounts;
• an explicit period for remedying the default that is reasonable in light of the nature of the facility;
• an express warning that, failing remedy within that period, the lender will rely on the early repayment clause and demand repayment of the outstanding principal;
• the date and signature of an authorised person, together with a method of sending that preserves proof of receipt.

The recurring weak point in institutional recovery files is the third and the fourth: a letter that demands the arrears without announcing acceleration does not alert the debtor to the risk incurred, and a formal notice followed by a declaration of acceleration the next day deprives the remedy period of any substance. The declaration of acceleration must then be the subject of a separate, dated instrument, notifying the immediate repayability of the principal and the updated statement of account. Merging the two acts in a single letter is the most commonplace cause of failure of acceleration.

The formalities also affect penalties. Article 1231-5 of the French Civil Code specifies that, except in the case of final non-performance, the penalty is incurred only when the debtor has been put on notice. The contractual default indemnity, which is analysed as a penalty clause, therefore presupposes a regular formal notice. The same provision allows the court to moderate, even of its own motion, a manifestly excessive penalty, and to reduce it in proportion to the benefit obtained from partial performance, any contrary stipulation being deemed unwritten. An acceleration statement that includes a high lump-sum indemnity on a loan already three-quarters repaid is an exposed statement.

Acceleration and termination clause: two mechanisms, two sets of formalities

Confusion between early repayment and termination of the contract is frequent in enforcement documents. It is not neutral: the effects and the formalities differ.

Acceleration keeps the contract in place and makes what remained to fall due payable. Termination annihilates the contract and opens a regime of restitution and damages. In a loan contract, the termination clause and the early repayment clause often coexist, and the creditor must choose the basis it relies on, then stick to it.

If the basis chosen is the termination clause, Article 1225 of the French Civil Code imposes a written formality:

The termination clause specifies the undertakings whose non-performance will lead to termination of the contract. Termination is subject to an unsuccessful formal notice, unless it has been agreed that termination will result from the mere fact of non-performance. The formal notice produces effect only if it expressly mentions the termination clause.

The requirement that the formal notice expressly mention the termination clause is therefore statutory, and not a construct of the courts. A formal notice that merely demands the arrears, without referring to the termination clause, produces no effect under Article 1225.

If the creditor prefers unilateral termination by notification, Article 1226 requires three steps: a prior formal notice, except in cases of urgency, allowing a reasonable period and expressly stating that, failing performance, the creditor will be entitled to terminate the contract; then, if non-performance persists, a notice of termination setting out the reasons for it. The provision specifies that the creditor acts at its own risk and that, if the debtor goes to court, it is for the creditor to prove the seriousness of the non-performance. For a lending institution, this route should be reserved for situations where the seriousness of the breach can be shown by documents.

In home loans to individuals, the link is imposed by the text: Article L313-51 of the French Consumer Code ties the immediate repayability of the outstanding principal to the case where the lender is led to seek termination of the contract. In consumer credit, Article L312-39 allows the lender, in the event of default by the borrower, to demand immediate repayment of the outstanding principal plus interest fallen due but unpaid, plus an indemnity set according to a scale determined by decree, both provisions reserving the application of Article 1231-5 of the Civil Code.

The chronology on the institutional creditor's side: the decision timetable

The notice period under Article L313-12 of the French Monetary and Financial Code

For a facility granted to a business, the decision to cut off is not free. Article L313-12 of the French Monetary and Financial Code provides that any facility of indefinite duration, other than an occasional one, granted by a credit institution or a finance company to a business may be reduced or discontinued only on written notification and on expiry of a notice period fixed when the facility was granted, that period being, on pain of nullity of the termination of the facility, no less than sixty days. The provision reserves two exemptions from notice, valid whether the credit facility is of fixed or indefinite duration: seriously reprehensible conduct by the beneficiary of the credit, and the beneficiary's situation proving to be irremediably compromised. Failure to comply with these provisions may give rise to pecuniary liability of the institution.

In a banking relationship combining an authorised overdraft, discounting and an amortising loan, the timetable must therefore be built line by line: acceleration of the loan follows the early repayment clause, while cutting off the facility of indefinite duration follows the statutory notice. Relying on an irremediably compromised situation to dispense with notice presupposes being able to document it as at the date of notification, not after the event.

Informing the guarantor who is an individual

Article 2303 of the French Civil Code, resulting from Ordinance No. 2021-1192 of 15 September 2021 and applicable since 1 January 2022, including to earlier suretyships, requires the professional creditor to inform any guarantor who is an individual (caution) of the default of the principal debtor from the first payment incident not remedied within the month in which that payment fell due, on pain of forfeiture of the guarantee for interest and penalties accrued between the date of that incident and that of the information. The provision adds that, in the relations between the creditor and the guarantor, payments made by the debtor during that period are applied first to principal.

This one-month period runs well before the decision to declare acceleration. A recovery procedure that triggers information to guarantors only when early repayment is declared mechanically organises its own forfeiture of interest.

The declaration and its statement of account

The declaration itself must be dated, notified to the debtor, and accompanied by a final statement of account distinguishing the outstanding principal, the unpaid instalments, the accrued interest, the default interest and the contractual indemnity. It is this statement that will be reproduced in the summons, in the filing of the claim and, where applicable, in the commandement (order to pay). Inconsistencies between the three documents are a classic ground of challenge.

Unenforceability of acceleration against co-obligors and guarantors

This is the point that recovery departments underestimate most. Article 1305-5 of the French Civil Code, in the wording resulting from Article 11 of Law No. 2018-287 of 20 April 2018, states:

Acceleration incurred by a debtor cannot be enforced against its co-obligors, even jointly liable ones, or against its guarantors.

The wording resulting from the 2016 ordinance referred only to co-obligors. The addition of guarantors by the Law of 20 April 2018 was given interpretative effect by paragraph I of Article 16 of that law, which means it applies to earlier situations.

The practical consequence is clear: acceleration validly declared against the borrower does not, by itself, make the whole debt due against the guarantor. A summons for payment of the entire principal served on the guarantor solely on the basis of acceleration declared against the principal debtor exposes the creditor to dismissal. The text does not settle whether the creditor may pursue the guarantor as the instalments fall due, or after a demand specific to the guarantor; these solutions are a matter of case law and must be checked file by file. In terms of procedural strategy, the rule requires in any event that the guarantor be treated as an autonomous debtor, with its own demand and its own statement of account.

The consequences of a wrongly declared acceleration for recovery

Access to enforcement

Article L111-2 of the French Code of Civil Enforcement Procedures makes enforcement subject to an enforceable title recording a claim that is certain, liquidated and due. If acceleration is set aside, the principal ceases to be due. Instalments fallen due and unpaid remain owed, but the scope of the proceedings is reduced accordingly, which may make a real estate attachment launched on the whole principal disproportionate. The precise civil consequences of an irregular acceleration, whether the time limit is maintained, the fate of the claim for payment of the principal, the characterisation of the sanction, depend on case-law solutions that must be sourced case by case, but the operational risk is constant: loss of time, loss of rank, an order to pay costs and, in real estate files, lapse of the commandement.

The protective fallback

Where due status is open to question, the useful reflex is not to force enforcement but to secure the asset base. Article L511-1 of the French Code of Civil Enforcement Procedures allows any person whose claim appears well founded in principle to ask the court for authorisation to take a protective measure over the debtor's assets, without prior commandement, if the person shows circumstances likely to threaten recovery. The measure takes the form of a protective attachment (saisie conservatoire) or a judicial security. The standard of proof is therefore markedly lower than for enforcement: a claim disputed as to its due status may remain well founded in principle. For an institutional creditor, the sequence of a protective measure followed by an action on the merits is often preferable to premature enforcement based on a fragile acceleration. On the conditions and time limits of this measure, see our analysis of protective attachment carried out before judgment.

Judicial neutralisation of due status

Even when validly declared, acceleration is not immune from a grace period. Article 1343-5 of the French Civil Code allows the court, taking into account the debtor's situation and having regard to the creditor's needs, to postpone or spread payment within a limit of two years. The decision suspends enforcement proceedings already commenced, and the increases in interest or penalties provided for in the event of delay are not incurred during the period set, any contrary stipulation being deemed unwritten. A lender that anticipates a request for time to pay should document its own needs, which the text expressly invites the court to take into account.

Acceleration and insolvency proceedings: due status, filing, rank

The distinction between the proceedings is imperative and often poorly stated in internal recovery notes.

In safeguard proceedings and court-supervised reorganisation proceedings, Article L622-29 of the French Commercial Code is unambiguous: the opening judgment does not make claims not yet due on the date of its delivery payable. Any contrary clause is deemed unwritten. An early repayment clause triggered by the opening of proceedings is therefore deprived of effect. Only an acceleration validly declared before the opening judgment produces effect.

In compulsory liquidation, Article L643-1, in the wording resulting from Article 5 of Law No. 2022-172 of 14 February 2022, provides that the judgment opening or ordering liquidation makes claims not yet due payable for which the estate seized by effect of the proceedings constitutes the security. This restriction, introduced in 2022, does not apply to proceedings in progress on the day the text entered into force. The same article delays due status where the court authorises continuation of the business on the ground that a total or partial sale is conceivable: claims not yet due are then payable on the date of the judgment ruling on the sale or, failing that, on the date on which continuation of the business ends.

Article L622-21 moreover closes the door to any catching up. The opening judgment interrupts or prohibits actions aimed at ordering the debtor to pay a sum of money and at termination of a contract for failure to pay a sum of money, and stops or prohibits any enforcement proceedings against movables and immovables alike. A lender that did not declare acceleration before the opening cannot regularise it by a later action. What remains possible for the creditor after the opening judgment is set out in our article on the stay of individual proceedings.

That leaves the filing of the claim, which is the tipping point for rank. Article L622-25, in the wording resulting from Ordinance No. 2021-1193 of 15 September 2021, requires the filing to state the amount of the claim due on the day of the opening judgment with an indication of the sums to fall due and the date of their maturity, and to specify the nature and base of the security with which the claim is secured, if any, and, where applicable, whether the contractual security interest in property was created over the debtor's assets to secure the debt of a third party. The very structure of the filing therefore depends on the fate of the acceleration: if it is effective, the whole amount is declared as due; if it is not, the creditor must declare the amount due and break down the sums to fall due with their dates. A filing built on an acceleration that is later set aside will have to be corrected, in conditions that are not always open.

On filing deadlines, Article L622-24 of the French Commercial Code was amended by Law No. 2025-1403 of 30 December 2025, some of its provisions applying only to insolvency proceedings opened and compulsory liquidations ordered from 1 January 2027. The applicable wording must be checked case by case before any time limit is cited.

As to the effect of acceleration on the ranking of security interests, it deserves cautious treatment: the texts govern due status and the content of the filing, not the hierarchy of priorities. The registration of a provisional judicial mortgage on the approach of an opening, in particular, is a matter for discussion on other grounds.

Limitation: two periods, one starting point to be documented

Article 2224 of the French Civil Code subjects personal or movable actions to a limitation period of five years from the day on which the holder of a right knew or should have known the facts enabling it to be exercised. Article L218-2 of the French Consumer Code reduces to two years the action of professionals for goods or services supplied to consumers. Neither fixes the starting point in the case of acceleration, a question that is a matter of case law and turns on the distinction between unpaid instalments and principal that has become due. In a portfolio of claims against individuals, this uncertainty requires each incident and each interrupting act to be dated precisely, and no file to be left dormant on the ground that acceleration has been declared.

Conclusion

Acceleration is not a letter, it is a sequence: information to the guarantor within the month of the incident, a formal notice identifying the contract, the arrears, a remedy period and the warning of early repayment, then a separate declaration with a final statement of account. Each of these links can be challenged individually, and the loss of a single one defeats due status, and therefore enforcement within the meaning of Article L111-2 of the French Code of Civil Enforcement Procedures. Our view, on high-stakes recovery files, is that the time gained by cutting off quickly is almost always lost at the litigation stage: an acceleration declared three weeks later but beyond reproach is worth more than a fragile immediate repayment demand.

Before launching an attachment on the basis of acceleration, have the complete sequence audited by someone outside the file, and check at the same time whether a protective measure based on Article L511-1 would secure your asset base better than contestable enforcement. If insolvency proceedings are foreseeable, the question is no longer only to declare acceleration but to declare it before the opening judgment and to build the filing of the claim accordingly.

Frequently asked questions

Is a registered letter enough to give formal notice before acceleration? Article 1344 of the French Civil Code admits formal notice either by a summons or an instrument containing a sufficient demand, or, if the contract so provides, by the mere fact that the obligation has fallen due. A registered letter with acknowledgement of receipt may constitute an instrument containing a sufficient demand, provided it is a formal demand: identification of the contract, amount of the arrears, remedy period and explicit warning that the early repayment clause will be invoked. A mere accounting reminder does not fulfil that function. A summons by a commissaire de justice remains preferable where proof of receipt is likely to be disputed.

Does acceleration declared against the borrower make the debt due against the guarantor? No. Article 1305-5 of the French Civil Code provides that acceleration incurred by a debtor cannot be enforced against its co-obligors, even jointly liable ones, or against its guarantors. The addition of guarantors results from Article 11 of Law No. 2018-287 of 20 April 2018, to which paragraph I of Article 16 of that law gave interpretative effect. The creditor must therefore build a separate action against the guarantor and cannot content itself with relying on the acceleration declared against the principal debtor.

Can a bank overdraft be cut off at the same time as acceleration of a loan is declared? Not on the same timetable. Article L313-12 of the French Monetary and Financial Code requires, for any facility of indefinite duration other than an occasional one granted to a business, written notification and a notice period fixed when it was granted, which may not be less than sixty days on pain of nullity of the termination. The only exemptions in the provision are seriously reprehensible conduct by the beneficiary of the credit and an irremediably compromised situation, exemptions valid whether the credit facility is of fixed or indefinite duration. Failure to comply with these rules may give rise to pecuniary liability of the institution.

Does the judgment opening court-supervised reorganisation proceedings make claims payable at a future date due? No. Article L622-29 of the French Commercial Code provides that the opening judgment does not make claims not yet due on the date of its delivery payable, any contrary clause being deemed unwritten. Early repayment by operation of law arises only in compulsory liquidation, under Article L643-1, and, in the wording resulting from Law No. 2022-172 of 14 February 2022, for claims not yet due for which the estate seized by effect of the proceedings constitutes the security. The same article delays due status where continuation of the business is authorised with a view to a sale.

What can be done if the due status of the claim is disputed but the debtor is arranging its own insolvency? The useful fallback is the protective measure under Article L511-1 of the French Code of Civil Enforcement Procedures. A creditor whose claim appears well founded in principle may obtain authorisation from the court to carry out a protective attachment or a judicial security, without prior commandement, if it shows circumstances likely to threaten recovery. The standard is less demanding than that of Article L111-2, which reserves enforcement to the holder of an enforceable title recording a claim that is certain, liquidated and due.

Is the contractual default indemnity automatically due after acceleration? No. Article 1231-5 of the French Civil Code reserves to the court the power to moderate, even of its own motion, a manifestly excessive penalty and to reduce it in proportion to the benefit obtained from partial performance, any contrary stipulation being deemed unwritten. The same provision specifies that, except in the case of final non-performance, the penalty is incurred only when the debtor has been put on notice. In consumer credit and home loans, Articles L312-39 and L313-51 of the French Consumer Code expressly refer to Article 1231-5 and make the indemnity subject to a scale set by decree.

Can the court neutralise immediate repayability after a valid acceleration? Yes, to a certain extent. Article 1343-5 of the French Civil Code allows the court to postpone or spread payment within a limit of two years, taking into account the debtor's situation and having regard to the creditor's needs. Its decision suspends enforcement proceedings already commenced, and the increases in interest or late-payment penalties are not incurred during the period set, any contrary stipulation being deemed unwritten. The provision excludes maintenance debts.
