Real Property Seizure: Only Submissions Filed with the Registry Can Be Used to Apply for an Extension of the Payment Demand (Cass. 2e civ., 5 March 2026, No. 23-16.398)

# How Do You Ask the Court to Extend a Payment Demand Constituting a Seizure of Real Property?

Cass. 2e civ., 5 March 2026, No. 23-16.398, Published in the Bulletin

What Was the Background to This Real Property Seizure?

The case decided by the French Supreme Court on 5 March 2026 originates in a real property seizure procedure launched in 2013 by the Caisse d’épargne et de prévoyance Hauts de France against Madame O. The bank’s claim was based on a notarial loan deed (acte de prêt notarié), an enforceable instrument (titre exécutoire) that allows enforcement proceedings to be commenced directly without a prior court decision.

A payment demand constituting a seizure of real property (commandement de payer valant saisie immobilière) had been published on 30 September 2013 at the land registry (service de la publicité foncière). This demand is the starting act of real property enforcement proceedings and freezes the seized property: from its publication, the debtor can no longer sell or mortgage the property without the consent of the enforcing creditor.

The procedure then dragged on over time. The enforcement judge had to order the extension of the effects of the demand on two occasions. This situation illustrates a common reality: real property seizure proceedings can stretch over several years, in particular where the debtor challenges the proceedings or where procedural incidents occur.

In 2019, nearly six years after the initial demand, the bank again applied for an extension. It is the way in which the bank chose to seise the court that crystallised the dispute and, seven years later, led to this leading judgment of the French Supreme Court.

A further element complicated the procedure: the death of the notary who drew up the deed, who had initially been joined as a third-party guarantor in the proceedings. His successors in title had to resume the appeal proceedings in 2021, adding an estate dimension to an already complex dispute.

What Is an Application to Extend a Payment Demand?

The payment demand constituting a seizure of real property takes effect for a limited period only. Beyond that period, if the property has not been sold, the creditor must ask the court to extend the effects of the demand to prevent it from lapsing.

This time limit is intended to protect the debtor against proceedings that would otherwise drag on indefinitely without result. It also reflects a balance between the creditor’s right to recover its claim and the debtor’s right not to see their real estate assets frozen indefinitely by a seizure procedure.

An application for an extension may be necessary for several reasons: court challenges that delay the sale, difficulties in valuing the property, the search for an amicable arrangement between the parties, or procedural incidents as in this case.

In the present case, the bank had already obtained two successive extensions before seeking a third in 2019. This multiplication of extensions reflects the exceptional length of this real property seizure procedure, which began in 2013 and was still pending in 2026, the date of the judgment of the French Supreme Court.
The enforcement judge has a discretionary power to grant or refuse the extension. They must verify that the reasons for the delay are legitimate and that the creditor has not been negligent in conducting the proceedings. This verification presupposes that the application has been validly brought before them, which brings us back to the heart of the dispute.

What Procedural Problem Arose in This Case?

The dispute concerns a question that appears technical but has major legal consequences: by what procedural instrument must the creditor seise the enforcement judge of an application to extend the payment demand?

This question points to a fundamental distinction in civil procedure between two ways of seising the court: the writ of summons (assignation) on the one hand, and the filing of submissions (conclusions) with the registry on the other. These two procedural techniques are governed by different rules and formalities.

How Had the Bank Seised the Court?

The Caisse d’épargne et de prévoyance Hauts de France chose to seek the extension by writ of summons. In practice, the bank had a bailiff serve two writs of summons on 4 and 8 July 2019 on Madame O., summoning her before the enforcement judge to rule on the application for an extension.

This choice may seem logical at first sight: the writ of summons is the most common way of seising a court in civil matters. It guarantees that the defendant is fully informed of the proceedings brought against them and of the claims made against them. The bailiff travels to the defendant, hands over the instrument in person or in accordance with the statutory methods of service, and the defendant has a period of time in which to prepare their defence.

From the point of view of the creditor bank, this approach had a certain logic: after several years of proceedings, it wished to formally restart the enforcement by a solemn instrument whose receipt by the debtor could not be disputed.

However, this approach overlooked the specific features of the real property seizure procedure, which is subject to particular procedural rules distinct from those applicable to ordinary civil proceedings. These special rules are laid down by the Code of Civil Enforcement Procedures (code des procédures civiles d’exécution), the text that governs all methods of compulsory enforcement.

What Objection Did the Debtor Raise?

Madame O., represented by her counsel, immediately challenged the regularity of this seisin. She raised a plea of inadmissibility (fin de non-recevoir) based on non-compliance with Article R. 311-6 of the Code of Civil Enforcement Procedures.

The debtor’s argument rested on a precise analysis of the applicable text. Article R. 311-6 of the Code of Civil Enforcement Procedures expressly provides that any challenge or incidental application in the context of a real property seizure procedure must be made by filing with the registry submissions signed by a lawyer.

According to Madame O., the application for an extension is undeniably an incidental application: it does not start a new procedure but forms part of the real property seizure procedure already under way since 2013. It therefore had to comply with the specific formalities imposed by Article R. 311-6, namely the filing of submissions with the registry.

The writ of summons served by the bank, even though it emanates from a bailiff and complies with all the formalities specific to this type of instrument, does not correspond to the method of seisin provided for by the text. It would therefore be an irregular seisin of the court, justifying the inadmissibility of the application.

This line of defence was particularly clever because the debtor did not have to show that she suffered any prejudice as a result of this irregularity. In procedural matters, certain rules are matters of public policy and their breach automatically results in nullity or inadmissibility, regardless of any harm suffered.

What Position Did the Court of Appeal of Amiens Take?

At first, the enforcement judge seised by the writ of summons gave a guidance judgment (jugement d’orientation) on 26 July 2019, ordering the extension of the effects of the demand for a further period of two years. This judgment implicitly validated the use of a writ of summons, evidently considering that the court had been validly seised.

Madame O. appealed against this decision. The case was therefore brought before the First Civil Chamber of the Court of Appeal of Amiens, which gave its judgment on 21 March 2023, upholding the enforcement judge’s decision.

The Court of Appeal’s reasoning rested on an extensive interpretation of procedural formalities. For the judges in Amiens, since a writ of summons is equivalent to submissions, an incidental application in real property seizure proceedings could validly be made either by lawyer’s submissions or by writ of summons.

This position reflected a pragmatic approach: a writ of summons necessarily contains the claimant’s claims and the grounds for them, just like submissions. Why, then, formally penalise the creditor who chose a more solemn method of seisin, one that better guarantees that the debtor is informed?

The Court of Appeal essentially considered that there was a functional equivalence between a writ of summons and submissions: both instruments fulfil the same function of informing the defendant and seising the court. A flexible interpretation of the texts would therefore require accepting either method of seisin.

This analysis, despite its apparent logic, disregarded the very wording of Article R. 311-6 of the Code of Civil Enforcement Procedures, which provides for only one method of seisin: the filing of submissions with the registry. It is precisely this disregard that the French Supreme Court is going to penalise.

Why Does the French Supreme Court Quash the Appeal Judgment?

In its judgment of 5 March 2026, the French Supreme Court firmly censures the reasoning of the Court of Appeal of Amiens. It quashes and sets aside the judgment in all its provisions, criticising the lower courts for having breached Article R. 311-6 of the Code of Civil Enforcement Procedures.

The highest court restates the principle with a clarity that leaves no room for ambiguity: the incidental application for an extension had to be made by filing with the registry submissions signed by a lawyer, on pain of inadmissibility raised by the court of its own motion, in order to be decided within the real property seizure procedure.

This decision forms part of the French Supreme Court’s settled case law, which ensures scrupulous compliance with procedural rules in the field of enforcement. Formalities are not conceived as an arbitrary constraint, but as an essential guarantee of the rights of the defence and of legal certainty.

What Exactly Does Article R. 311-6 of the Code of Civil Enforcement Procedures Say?

Article R. 311-6 of the Code of Civil Enforcement Procedures, in its first two paragraphs referred to by the French Supreme Court, provides:

“Unless otherwise provided, any challenge or incidental application is made by filing with the registry submissions signed by a lawyer. Submissions and documents are communicated between lawyers in accordance with the conditions laid down in Article 766 of the Code of Civil Procedure. Submissions are communicated by service on a debtor who has not appointed a lawyer.”

This text establishes a clear principle subject to an initial reservation. The principle is the filing with the registry of submissions signed by a lawyer for any challenge or incidental application. The reservation, “unless otherwise provided”, refers to the special provisions of the Code that may provide for another method of seisin for certain particular applications.

In this case, no special provision provides for a different method of seisin for applications to extend the payment demand. The principle therefore applies in full: only the filing of submissions with the registry is permitted.

The French Supreme Court emphasises that this text also organises communication between the parties: submissions and documents are exchanged between lawyers in accordance with Article 766 of the Code of Civil Procedure (electronically via the RPVA, the lawyers’ private virtual network). If the debtor has not appointed a lawyer, communication is made to them by service through a bailiff.

This procedural system has several advantages. It fits within the real property seizure procedure already under way, avoiding a formal break that could complicate the monitoring of the case. It guarantees that the registry, which centralises the entire procedure, keeps track of applications. Finally, it ensures speed, since submissions are immediately added to the file without the service periods specific to writs of summons.

What Is the Sanction for an Irregular Seisin?

The French Supreme Court is explicit: the sanction for an application made by writ of summons instead of submissions is inadmissibility, to be raised by the court of its own motion.

This wording deserves explanation. Inadmissibility means that the court cannot examine the merits of the application. It must note the procedural irregularity and declare the application inadmissible without ruling on the merits of the extension sought.

The fact that this inadmissibility is “raised of the court’s own motion” is crucial. Even if the debtor does not raise the irregularity, the court is obliged to note it and draw the consequences. It cannot cure an irregular seisin. It cannot consider that, since the debtor makes no complaint, it may disregard it.

This rigour is explained by the nature of the rules at issue. The rules on jurisdiction and procedure in the field of enforcement are matters of public policy. They protect not only the particular interest of the debtor but also the general interest attached to the proper administration of justice and compliance with legal procedures.

In this case, the French Supreme Court does not merely quash the appeal judgment. It also orders the bank to pay the costs, as well as €3,000 to Madame O. under Article 700 of the Code of Civil Procedure (compensation for irrecoverable costs, in particular lawyers’ fees).

These financial orders are a clear signal to enforcing creditors: failure to comply with procedural rules has a cost, not only in terms of lost time but also financially.

What Is the Practical Scope of This Judgment?

The judgment of 5 March 2026 was published in the Bulletin of the French Supreme Court, which gives it enhanced normative weight. Such publication signals that the highest court intends to lay down a principle of law designed to guide all lower courts.

Beyond the particular case decided, this judgment establishes a clear rule applicable to all real property seizure procedures: any incidental application, whether an extension of the demand, a challenge to the claim, an application for release (mainlevée) or any other application forming part of the pending proceedings, must imperatively be made by filing submissions with the registry.

What Are the Consequences for Enforcing Creditors?

For banks and other creditors commencing real property seizure procedures, this judgment calls for heightened vigilance in complying with procedural formalities.

Legal advisers and lawyers acting on behalf of creditors must now systematically favour the filing of submissions with the registry for any incidental application in a real property seizure procedure, even if a writ of summons seems to them more solemn or more secure.

This requirement applies in particular to the following applications, all of which are incidental applications in a pending real property seizure procedure:

– Application to extend the effects of the payment demand
– Application to postpone the auction hearing
– Application to set a new reserve price
– Application to amend the conditions of sale
– Application for authorisation to visit the seized property

Failure to comply with these formalities exposes the creditor to having its application declared inadmissible, with all the consequences that entails. If an extension is not obtained in time, the demand lapses. The creditor must then restart the entire procedure from the beginning: service of a new demand, new publication at the land registry, fresh challenges becoming possible.

This obligation to start again presents several major risks for the creditor. First, a risk of limitation: if in the meantime the limitation period for the claim expires, the claim may become irrecoverable. Next, a financial risk: each procedural step generates costs (bailiff, lawyer, land registry publication) that accumulate. Finally, a risk of the debtor’s insolvency worsening: during the months or years needed to restart the procedure, the debtor’s financial position may deteriorate.

What Protections Do Debtors Whose Property Is Seized Have?

From the point of view of a debtor facing a real property seizure, this judgment is an important procedural guarantee. It confirms that procedural rules are not mere administrative formalities but effective protections of the rights of the defence.

Debtors can now rely on this judgment to challenge any incidental application that is not made in accordance with the statutory requirements. In practical terms, if a debtor receives a writ of summons for an application to extend or any other incidental application in a real property seizure, they must systematically raise inadmissibility before the court.

This challenge does not require showing any particular prejudice. The mere finding of the irregularity is sufficient. The debtor does not have to prove that they were prevented from defending themselves or that they suffered harm. The procedural irregularity is sufficient in itself.

Moreover, the judgment recalls that the court must raise this inadmissibility of its own motion. Even if the debtor has no lawyer or is unaware of this technical rule, the enforcement judge irregularly seised by a writ of summons should note the inadmissibility.

This protection operates in a context in which debtors whose property is seized are often in a vulnerable situation: financial difficulties, lack of legal information, absence of representation by a lawyer in the early stages of the procedure. The rigorous formalities imposed by Article R. 311-6 thus constitute a safeguard against proceedings that would not scrupulously comply with the legal framework.

Conclusion

The French Supreme Court’s judgment of 5 March 2026 is a firm reminder of the procedural rules applicable to real property seizures. By quashing the judgment of the Court of Appeal of Amiens, which had accepted that an application for an extension could be made by writ of summons, the highest court reaffirms the mandatory nature of Article R. 311-6 of the Code of Civil Enforcement Procedures.

This decision illustrates the rigour of procedural formalities in the field of enforcement. Far from being mere technical subtleties, procedural rules are fundamental guarantees for the balance between the creditor’s right to recover its claim and the debtor’s right to defend themselves within a protective legal framework.

For creditors and their advisers, this judgment calls for heightened vigilance in the choice of procedural instruments. Any incidental application in a real property seizure must now imperatively be made by filing submissions with the registry, on pain of inadmissibility. The writ of summons, the traditional method of seisin in ordinary civil procedure, has no application in this specific context.

For debtors, this case law offers an effective defence against irregular proceedings. It recalls that even in the urgency of compulsory recovery, scrupulous compliance with legal forms remains an unavoidable requirement of the rule of law.

This case, which will have lasted more than thirteen years since the initial demand in 2013, also demonstrates the complexity and potential length of real property seizure procedures. It recalls the importance, for all parties, of a precise knowledge of the applicable rules in order to avoid procedural errors that can lose years and permanently compromise the outcome of a procedure.
