Paris Court of Appeal, Pôle 4, Chamber 9 A, 4 June 2026, RG No. 25/08459
🔑 Key takeaways
- On 5 February 2025, a lender had obtained a judgment ordering a borrower to pay €22,459.90, by a judgment “deemed adversarial” (réputé contradictoire), that is, delivered in his absence.
- The summons had been served on 22 October 2024 under the procedure of Article 659 of the Code of Civil Procedure (code de procédure civile) (addressee with no known domicile or residence), at an address where the borrower had never lived.
- Yet, on the credit agreement, the borrower was domiciled at another address, known to the bank: no search had been made there, whereas the judgment itself was then, “curiously”, duly served there.
- The Paris Court of Appeal declares the summons void for a defect of form, for lack of sufficient diligence on the part of the court bailiff (commissaire de justice), the prejudice being established by the deprivation of the right of defence and of the double degree of jurisdiction.
- The annulment of the summons entails that of the judgment; this annulment deprives the appeal of its devolutive effect, so that the court is seised of no claim and sends the parties back to seek better redress.
- The bank, which loses, bears all the costs of the first-instance and appeal proceedings, plus €1,000 under Article 700.

What happened in this case?
The story is the sadly commonplace one of a borrower who learns of his trial once it is too late. An institution specialising in consumer credit had granted a loan to an individual. Repayments having ceased, the lender started recovery proceedings before the protection litigation judge (juge des contentieux de la protection) of the local court (tribunal de proximité) of Bobigny.
By a judgment of 5 February 2025, that judge ordered the borrower to pay the principal sum of €22,459.90, plus interest at the contractual rate of 5.75% per annum from 22 March 2024 on the sum of €20,768.37, and at the statutory rate on the sum of €1,661.47 corresponding to the termination indemnity, as well as €800 under Article 700 of the Code of Civil Procedure and costs. This judgment was delivered “deemed adversarial”, a mention which in itself betrays the problem: the borrower was not there. He had not appeared, nor had anyone for him.
Why this absence? Because the summons to appear had been served on 22 October 2024 at an address in Drancy where, as he argued before the court, the borrower had never lived. The document had been served under the procedure of Article 659 of the Code of Civil Procedure, the one the court bailiff uses when the addressee has “no known domicile, residence or place of work”. On site, the bailiff had met a person who stated that he did not know the addressee.
Having discovered the judgment, which, for its part, had indeed been served at another address, the borrower appealed on 3 May 2025. Before the Paris Court of Appeal, he sought the annulment of the summons and, as a consequence, that of the judgment. The bank, for its part, admitted the error in the address, but argued that the borrower had suffered no prejudice: admittedly he had been unable to be present at first instance, but he had been able to appeal. A line of reasoning that the court did not follow.
A judgment delivered although the defendant has not appeared, but which is treated as adversarial (and not by default) because it is open to appeal or because the summons was served in person. The mention “deemed adversarial” therefore signals, in practice, that the person ordered to pay did not take part in the debate.
Service in person, at the domicile, Article 659: what are we talking about?
To understand the decision, one must grasp the mechanics of the service of documents (signification), that is, the way a procedural document (here, a summons) is officially brought to the attention of its addressee by a court bailiff (commissaire de justice), the former “huissier de justice“. The Code of Civil Procedure sets out a very precise hierarchy, from the most protective to the most degraded.
Service is the official delivery of a procedural document by a court bailiff. It starts time limits running and conditions the regularity of the trial: if done badly, it can deprive the addressee of the opportunity to defend himself, which justifies its nullity.
Why is service in person the rule?
Under Article 654 of the Code of Civil Procedure, service must be made in person. That is the principle. The court bailiff must first seek to hand the document directly to its addressee. Only if this delivery “in person” proves impossible may the document be served by other means.
Article 655 then provides for service at the domicile or residence: if delivery in person is impossible, the copy may be handed to any person present, who must accept it and state his surname, first names and capacity; a notice of call is left. Article 656 governs the situation where no one can or will receive the copy: service is deemed made at the domicile on condition that the court bailiff has verified, and stated in the document, that “the addressee does indeed live at the address given”. Article 658 also requires that an ordinary letter be sent notifying the person concerned of the service.
Only at the very last step, where the addressee has “no known domicile, residence or place of work”, does Article 659 authorise the court bailiff to draw up a report setting out the efforts made to find the addressee. This document, often called a “PV 659” or “report of unsuccessful searches” (procès-verbal de recherches infructueuses), then counts as service of the summons, on condition that a registered letter with acknowledgment of receipt containing a copy of the report and of the document is sent to the addressee at his last known address.
The hierarchy of methods of service
① In person (Art. 654): handed over personally : the rule
↓ if impossible
② At the domicile / residence (Art. 655-656): handed to a third party who is present, or deposited after verifying that the person “does indeed live at the address”
↓ if no known domicile, residence or workplace
③ Report of unsuccessful searches (Art. 659): the last resort, subject to genuine efforts
What is a report of unsuccessful searches (Article 659)?
This is the document drawn up by the court bailiff when the addressee has no known domicile, residence or place of work. It sets out “with precision” the efforts made to find the person. This report counts as service, but only if the searches are genuinely described in it and are serious.
The crucial point, which the Paris Court of Appeal highlights, is that this method of delivery is not a convenience left to the bailiff’s discretion. It follows from the texts that, service in person being the rule, the court bailiff is required to state in the document not only the concrete investigations he carried out to find the addressee, but also the concrete and precise circumstances preventing such service. In other words, a terse PV 659, which merely records that a person met on site “does not know” the addressee, is not enough.
And above all: the judge is not bound by the mere existence of the report. The court recalls that “it is therefore required to verify whether the efforts mentioned in the report are sufficient”. The review is real, and it concerns the concrete content of the searches.
Why were the court bailiff’s efforts insufficient?
This is where the case tips. The court notes that the summons had been served on 22 October 2024 at an address in Drancy, supposedly the borrower’s “last known address”, where the court bailiff states that he went and met a person who declared that he did not know the addressee.
But, and this is decisive, on the credit agreement the borrower was domiciled at a completely different address. In the bank’s own eyes, that address was the borrower’s last known domicile. Yet there was no evidence of “the slightest search at that address”. Worse still, the court points out that the judgment, for its part, was “then curiously duly served” at that address: proof, by implication, that the address in the agreement was perfectly usable and known.
The summons, the document that opens the trial and makes it possible to defend oneself, is served at an address where the borrower never lived, via a PV 659. But the judgment ordering payment is served without difficulty at the address given in the credit agreement. The bank therefore did have this address: it was simply not used at the moment when it would have protected the debtor.
The conclusion is inescapable: in these circumstances, the document containing the summons of 22 October 2024 cannot be regarded as regular. Recourse to Article 659 presupposed that the borrower had “no known domicile, residence or place of work”. That condition was not met, since an address appeared in the agreement and no verification had been carried out there. The report of unsuccessful searches cannot be used to circumvent the obligation to genuinely search for the addressee where he is supposed to be found.
Nullity for defect of form and prejudice: how did the borrower succeed?
The irregularity of a document is not always enough to entail its nullity. In French law, the nullity of procedural documents for a defect of form is subject to a demanding rule, laid down by Article 114 of the Code of Civil Procedure: nullity can be pronounced only if the person invoking it proves the prejudice (grief) caused to him by the irregularity, “even where it concerns a substantial formality or one of public policy”. The court also recalls, via Article 649, that the nullity of court bailiffs’ documents is governed by the rules governing procedural nullities.
A defect of form in a procedural document entails its nullity only if the party invoking it shows that it caused him a “prejudice” (grief), that is, concrete harm in the exercise of his rights. This requirement, laid down by Article 114 of the Code of Civil Procedure, applies even to substantial formalities or those of public policy.
It is precisely on this ground that the bank tried to resist: it admitted the error in the address, but argued that there was no prejudice, since the borrower had been able to appeal. The argument is clever, but the court firmly dismisses it. It finds that the borrower “was unable to learn of the proceedings brought against him, or to ensure his defence, and is thus deprived of a double degree of jurisdiction, which establishes the existence of a prejudice”.
The reasoning deserves a closer look, because it is strategically valuable. Having been able to appeal does not cure the prejudice: on the contrary, it reveals it. If appeal was the only route open, it is because the first-instance proceedings had taken place without the borrower. Yet an appeal is not a substitute for first instance: it is the second degree. By being unable to appear before the first judge, the borrower lost a degree of jurisdiction: he was able to put forward his arguments only once, instead of twice. That is real prejudice, and not a mere theoretical irregularity.
Accordingly, the court declares void, for a defect of form, the summons of 22 October 2024 and, as a consequence, the judgment.
Why does the court send the parties back to “seek better redress”?
The rest of the reasoning is more technical, but carries heavy practical consequences. Once the summons is annulled, the judgment flowing from it is also annulled, since it rests on a void originating document. Yet, the court specifies, “the annulment of the judgment resulting from the nullity of the originating document deprives the appeal of its devolutive effect”.
This is the mechanism by which an appeal transfers to the court of appeal the examination of the dispute judged at first instance. But where the judgment is annulled because the document that opened the trial was void, there is nothing left to “devolve”: the court cannot re-judge a dispute of which it was never properly seised.
The court draws the logical consequence: “the court is seised of no claim”. It therefore notes the absence of devolutive effect and sends the parties back to “seek better redress”. In concrete terms, this means that the court does not decide the question of the debt: it says neither that the borrower owes €22,459.90, nor that he does not. It notes that no court was properly seised, and invites the creditor to start the procedure again, if it wishes, this time serving a regular summons.
The chain of consequences
Irregular summons (Art. 659 without genuine efforts)
→ nullity of the summons (prejudice established)
→ nullity of the judgment that flowed from it
→ loss of the devolutive effect of the appeal
→ the court is seised of no claim
→ parties sent back to seek better redress + the bank bears all costs and €1,000 under Article 700
For the borrower, the result is a clear victory: the order to pay more than €22,000 disappears, and it is the bank that bears all the costs of the first-instance and appeal proceedings, as well as an allowance of €1,000 under Article 700 of the Code of Civil Procedure. The creditor who “loses” goes back to square one.
What is the practical scope for borrowers who are being sued?
This decision, although delivered by a court of appeal and described as “unpublished”, illustrates a fundamental point of vigilance in consumer credit litigation. Lenders recover unpaid debts on a mass scale. Debtors have often changed address, no longer respond, or are hard to locate. In this context, recourse to the report under Article 659 is extremely common: it makes it possible to obtain a judgment ordering payment without the debtor ever having learned of the trial.
The Paris Court of Appeal’s message is clear: Article 659 is not an easy route. It presupposes that the addressee is genuinely untraceable, and that the court bailiff has established this through concrete efforts. Where the creditor itself, the bank, has in its own contractual file an address that has not been explored, the PV 659 is fragile. The fact that the judgment could be served at that same address completes the demonstration that it was available.
The particular power of this ground must also be appreciated. Unlike a challenge to the amount of the debt or to the interest rate, the nullity of the summons does not merely reduce the order: it brings down the entire judgment, without the appeal judge having to examine the merits. The creditor obtains nothing and must start everything again, with, in the meantime, the risk that the limitation period has run or that the two-year forfeiture period specific to consumer credit (forclusion biennale) has become enforceable against it.
One limit can nevertheless be pointed out: the solution obviously does not release the borrower from his debt on the merits. The court does not say that the credit is not owed; it says that the trial was not properly commenced. Nothing prevents the lender from serving a new summons, this time at the right address. The victory is therefore procedural, but it is far from negligible: it restores to the borrower his right to defend himself, with two degrees of jurisdiction, and places on the creditor the cost and risk of a new procedure. It is often in this interval that room for negotiation arises, or even the outright discontinuance of the claim.
What reflexes should you adopt if you are convicted without having been notified?
Receiving service of a judgment whose existence you were unaware of is a distressing situation, but not one without a way out. Several checks are needed without delay, and the time limit to act is short: from service of the judgment, the appeal must in principle be lodged within one month.
The first reflex is to examine the summons and the way in which it was served. At what address? By what method: in person, at the domicile, or by report under Article 659? Does this address correspond to the one you gave to the lender, in particular the one appearing on your contract? If the summons was served at an address where you never lived, whereas another address was known to your creditor, the decision under comment shows that nullity is conceivable.
The second reflex is to gather the documents that establish your true domicile at the relevant period: credit agreement stating your address, rent receipts, bills, administrative supporting documents. These elements serve to show that the court bailiff could, and should, have found you.
The third reflex is to characterise your prejudice precisely: you were unable to appear, unable to put forward your defences (challenge to the statement of account, to the rate, to the forfeiture of the right to interest, to the forfeiture period), and you lost a degree of jurisdiction. It is this concrete demonstration that secures the nullity.
The appeal period runs from service of the judgment. Do not let this period pass thinking that “the trial is already lost”: it is precisely the appeal that allows you to raise the nullity of the summons. A quick review of your file by a lawyer is essential as soon as you receive the document.
Beyond the nullity of the summons, the appeal is also an opportunity to put forward, on the merits, all the grounds specific to consumer credit that your non-appearance at first instance had prevented you from raising: regularity of the credit offer, compliance with the formalities of the Consumer Code (code de la consommation), forfeiture of the right to interest, verification of creditworthiness, two-year forfeiture period. Nullity of the procedure and grounds on the merits are not mutually exclusive: they are cumulative in the defence strategy.
What to Remember
With this judgment of 4 June 2026, the Paris Court of Appeal recalls an obvious point too often mistreated in mass consumer credit litigation: no one can be ordered to pay without having been properly called to defend himself. The report under Article 659 is not a free pass; it requires genuine efforts, and the judge reviews their sufficiency. Where the creditor holds in its own file an address that has not been explored, the summons is fragile, and its nullity brings down the whole edifice, right up to the judgment ordering payment.
For the borrower who is being sued, the lesson is twofold. First, never consider that a judgment delivered in his absence is definitively final: the regularity of service is a ground of defence in its own right. Second, act quickly, because the time limits for appeal are short. Behind a simple “address error”, it is the fundamental right to be heard by a judge that is at stake.
