Creditors have effective means of enforcement at their disposal, including the attachment of bank accounts (saisie-attribution), which allows sums owed to be recovered directly. This procedure may, however, be challenged where it is irregular or infringes the debtor's rights. Understanding how to challenge an attachment of this kind is essential to protect one's financial interests and to assert one's rights before the enforcement judge (juge de l'exécution).
This guide sets out the legal basis for a challenge, the time limits to observe, the grounds that may be relied on and the procedure to follow in order to challenge a saisie-attribution effectively.
Legal basis of the saisie-attribution and conditions of validity
The saisie-attribution is founded on Articles L. 211-1 et seq. of the French Code of Civil Enforcement Procedures. This procedure allows a creditor holding an enforceable title to attach directly, in the hands of a third party (generally a bank), the sums owed to its debtor.
The validity of a saisie-attribution depends on strict conditions that the creditor must satisfy. The creditor must hold an enforceable title within the meaning of Article L. 111-3 of the French Code of Civil Enforcement Procedures: an enforceable court decision, a notarial deed bearing the enforcement formula, a title issued by a public-law legal entity and so classified by statute, or a title issued by the commissaire de justice (bailiff) in the event of non-payment of a cheque or of an agreement between creditor and debtor under the procedure of Article L. 125-1. The absence of an enforceable title, or its lack of enforceability, is a fundamental ground of challenge.
No prior formal demand for payment is required: Article L. 211-1 allows a creditor holding an enforceable title establishing a liquid and due claim to attach directly, in the hands of a third party, the debtor's claims for a sum of money. The only eight-day period specific to this procedure is that for notifying the attachment to the debtor, by act of a commissaire de justice, prescribed on pain of lapse by Article R. 211-3.
The attachment must relate to attachable claims. Certain sums enjoy statutory protection: the sum of a maintenance nature that the garnishee (tiers saisi) leaves at the disposal of an individual debtor, equal to the flat-rate amount of the active solidarity income (revenu de solidarité active) for a single claimant (Articles L. 162-2 and R. 162-2 of the French Code of Civil Enforcement Procedures), that is €651.69 as at 1 April 2026, family benefits, minimum social benefits, and sums paid as damages for personal injury. Attachment of unattachable sums is a substantial irregularity. The resources that escape attachment and the remedies open to the account holder are detailed in our article on attachment of a bank account by a bailiff.
The attachment notice, served on the third party by a commissaire de justice, contains, on pain of nullity, the particulars prescribed by Article R. 211-1: the name and address of the debtor or the name and registered office of the legal entity, a statement of the enforceable title, a separate breakdown of the sums claimed as principal, costs and accrued interest, increased by a provision for interest accruing during the period for challenge, an indication that the garnishee is personally liable to the creditor and is forbidden to dispose of the sums claimed up to the amount it owes the debtor, and reproduction of the provisions referred to in that article. The notice states the time at which it was served.
Time limits for challenging a saisie-attribution
A challenge to a saisie-attribution is subject to a precise timetable that the debtor must observe. Article R. 211-11 of the French Code of Civil Enforcement Procedures requires, on pain of inadmissibility, that the challenge be brought within one month of notification of the attachment to the debtor.
This one-month period is a strict time limit, sanctioned by inadmissibility of the challenge. It is not a clear-days period: in accordance with Article 641 of the French Code of Civil Procedure, it expires on the day of the following month bearing the same number as the day of notification, at midnight. Where the period expires on a Saturday, a Sunday or a public or non-working holiday, it is extended to the next working day (Article 642).
The notification of the attachment to the debtor is the starting point of the period. It is made by act of a commissaire de justice within eight days of the attachment, on pain of lapse, and must state in very prominent characters that challenges must be raised, on pain of inadmissibility, within one month by summons, together with the date on which that period expires and the competent court (Article R. 211-3). It follows the forms of service: delivery to the person, at the home, or under the arrangements of Article 659 of the French Code of Civil Procedure where the addressee has no known home, residence or place of work. An irregular notification may affect the starting point of the period for challenge.
The period cannot be extended by the judge. A debtor who has not raised a challenge within the period retains only the option of bringing, at his or her own cost, an action for recovery of undue payment before the competent court on the merits (Article L. 211-4, paragraph 3).
Admissible grounds of challenge
A challenge to a saisie-attribution may rely on distinct formal grounds or substantive grounds, the interplay of which determines the procedural strategy.
Formal grounds and procedural defects
Irregularities in the notification are a frequent ground. The notification must be served on the debtor in the forms of Articles 654 et seq. of the French Code of Civil Procedure and must contain, on pain of nullity, the particulars of Article R. 211-3: a copy of the attachment report, an indication of the period for challenge and its expiry date, designation of the competent court and, in the case of an attachment of an account, the amount of the sum of a maintenance nature left at the debtor's disposal.
The absence or inadequacy of the particulars in the attachment notice entitles the debtor to challenge. Article R. 211-1 requires particulars on pain of nullity: identification of the debtor, statement of the enforceable title, and a separate breakdown of the sums claimed as principal, costs and interest. Omission of these elements justifies annulment of the attachment.
Failure to comply with statutory time limits affects the validity of the procedure. An attachment that has not been notified to the debtor within eight days lapses (Article R. 211-3).
Substantive grounds
Challenging the enforceable title makes it possible to call into question the very basis of the attachment. The debtor may rely on extinction of the claim by payment, set-off, limitation or novation. Producing receipts, transfers or correspondence establishing payment is an effective means.
The non-enforceability of the claim results from the judge having granted time to pay, from an amicable payment schedule being performed, or from the existence of collective insolvency proceedings prohibiting individual enforcement. The debtor must produce the corresponding supporting documents.
Unattachable sums enjoy strict statutory protection. Besides the unattachable bank balance, certain claims cannot be attached: remuneration within the limit set by Article R. 3252-2 of the French Labour Code, social benefits, and dismissal payments in certain proportions. Attachment of these sums is a ground of nullity.
Procedure for challenge before the enforcement judge
A challenge to a saisie-attribution falls within the exclusive jurisdiction of the enforcement judge (juge de l'exécution), under Article L. 213-6 of the French Code of Judicial Organisation. The court with territorial jurisdiction is that of the place where the debtor resides (Article R. 211-10 of the French Code of Civil Enforcement Procedures).
Referral to the judge and formalities
The challenge is brought by summons served on the attaching creditor, for the first suitable hearing of the enforcement judge (Articles R. 211-11 and R. 121-11 of the French Code of Civil Enforcement Procedures). The summons reproduces, on pain of nullity, the provisions of Articles R. 121-8 to R. 121-10 on oral procedure. Representation by a lawyer is not compulsory where the claim arises from a debt or seeks payment of a sum not exceeding €10,000; above that amount it is compulsory (Articles L. 121-4 and R. 121-6).
The supporting documents are communicated to the opposing party: a copy of the attachment notice and of its notification, of the enforceable title and of all documents supporting the grounds relied on. A copy of the summons is lodged with the registry of the enforcement judge no later than the day of the hearing, on pain of lapse of the summons (Article R. 211-11).
Notification of the challenge is subject to its own rules. On pain of inadmissibility, the challenge is notified on the same day or, at the latest, on the next working day, by registered letter with acknowledgement of receipt, to the commissaire de justice who carried out the attachment. The party bringing the challenge informs the garnishee by ordinary letter (Article R. 211-11).
Investigation and interim measures
The enforcement judge has wide powers to order any useful investigative measure: expert appraisal, verification of handwriting, personal appearance of the parties. These measures make it possible to establish the facts alleged and to assess the validity of the grounds relied on.
The enforcement judge gives effect to the attachment for the uncontested portion of the debt, by a decision enforceable on the original (sur minute), and may, if neither the attaching creditor's claim nor the garnishee's debt is seriously open to challenge, order payment of a sum that the judge determines by way of interim relief (Article R. 211-12). In the case of an attachment of an account, the unavailability may be ended, by agreement of the parties or on the judge's decision, by the provision of an irrevocable guarantee up to the sums claimed (Article R. 211-21). The judge may also order the release (mainlevée) of any unnecessary or abusive measure (Article L. 121-2).
In cases of urgency, the enforcement judge may allow a summons to be served at the hour the judge indicates, even from hour to hour and on public or non-working holidays (Article R. 121-12). The sum of a maintenance nature provided for by Article L. 162-2 is left at the debtor's disposal without the debtor having to request it (Article R. 162-2).
Decision and means of appeal
The judgment on the challenge rules definitively on the validity of the attachment. In the event of a substantial irregularity, the judge annuls the attachment and orders its release with restitution of the sums taken. Damages may be awarded to compensate for the loss suffered.
An appeal against the judgment is open within fifteen days of its notification; it is lodged, investigated and decided under the rules of the short-notice or fixed-date procedure (Article R. 121-20). The appeal period and the appeal itself have no suspensive effect (Article R. 121-21). A stay of execution may be sought from the First President of the Court of Appeal, who grants it only if there are serious grounds for annulment or reversal (Article R. 121-22).
An appeal on points of law (pourvoi en cassation) is admissible only for violation of the law, lack of legal basis or contradictory reasoning. The Cour de cassation does not consider facts but only the law, which limits the chances of success of this extraordinary means of appeal.
Effects of the challenge on the attachment
The challenge does not call into question the assignment effect of the attachment, which operates from the attachment notice (Article L. 211-2). It does, however, defer payment of the creditor by the garnishee, unless the judge authorises payment of a sum that the judge determines (Article L. 211-5); the garnishee pays only after notification of the decision dismissing the challenge (Article R. 211-13). The request for an amicable release and the urgent measures that may be considered are presented in our guide to blocking a saisie-attribution.
Continued unavailability of the sums
The sums attached remain unavailable during the proceedings on the challenge: the garnishee may pay the creditor only after notification of the decision dismissing the challenge, unless the judge authorises otherwise (Articles L. 211-5 and R. 211-13). In the case of an attachment of an account, the attachment applies to the balance on the day of the attachment, which may be affected only, within the following fifteen working days, by pending transactions dated before the attachment (Article L. 162-1).
Crediting of the account remains possible after the attachment. Sums credited under transactions subsequent to the attachment are not caught by it; a creditor wishing to reach them must carry out a new attachment.
The saisie-attribution, being an act of enforcement, interrupts the limitation period of the attaching creditor's claim (Article 2244 of the French Civil Code).
Consequences of a successful challenge
Where the challenge is upheld by the judge, the attachment is annulled retroactively. This annulment takes effect from the origin of the attachment, which entails immediate restitution of the sums taken with interest at the statutory rate from the date of the deduction.
Damages may be awarded to the debtor to compensate for the loss caused by an irregular attachment. This loss is assessed in particular by reference to the financial consequences of the funds being unavailable: payment incidents, bank charges, or commercial loss resulting from the inability to meet commitments.
An order that the attaching creditor pay the costs generally accompanies annulment of the attachment. This order covers the procedural costs incurred by the debtor in obtaining release of the irregular attachment.
Special cases and complex situations
Attachment of a joint account
An attachment carried out on a joint account raises particular difficulties in determining the rights of each holder. It is notified to each of the account holders; if their names and addresses are unknown to the commissaire de justice, the latter asks the institution holding the account to inform them immediately of the attachment and of the amount of the sums claimed (Article R. 211-22).
The co-holder who is not the debtor has a right of challenge in order to assert his or her rights over the funds attached. The co-holder must establish the reality of his or her claim on the account by any means: origin of the payments in, bank correspondence, or witness evidence. This challenge may lead to the attachment being limited to the debtor's share alone.
A claim to ownership of sums by the co-holder who is not the debtor is made under the ordinary rules. It must be supported by probative and precise evidence making it possible to identify the sums belonging exclusively to him or her.
Multiple attachments
Competition between several attachments on the same account is governed by the rules of Article L. 211-2 of the French Code of Civil Enforcement Procedures. The attachment notice entails immediate assignment of the attached claim to the first attaching creditor; the later notification of other attachments, even from preferential creditors, does not call this assignment into question. Attachments notified to the third party on the same day are deemed simultaneous, and the attaching creditors then rank together. On the competition between a saisie-attribution and an attachment carried out by a public accountant, see our analysis of the administrative attachment in the hands of a third party (saisie administrative à tiers détenteur).
Challenging an attachment where there are multiple attachments may affect the distribution among creditors. Annulment of an earlier attachment benefits later creditors, whose rights are strengthened accordingly.
Protection of individual debtors
Individual debtors benefit from specific protections in matters of saisie-attribution. Besides the unattachable bank balance, over-indebtedness (surendettement) proceedings may affect the execution of the attachment through a stay of enforcement or partial write-off of debts.
The over-indebtedness commission may recommend the release of attachments that are disproportionate to the debtor's situation. Once approved by the judge, these recommendations are binding on creditors and justify challenging attachments that have lapsed.
Frequently asked questions
Can I challenge a saisie-attribution without a lawyer?
Representation by a lawyer is not compulsory before the enforcement judge where the claim arises from a debt or seeks payment of a sum not exceeding €10,000; above that amount it is compulsory (Articles L. 121-4 and R. 121-6 of the French Code of Civil Enforcement Procedures). In the first case, the debtor may serve the summons personally through a commissaire de justice. The technical nature of the procedure and the shortness of the time limits nevertheless make it advisable to instruct a lawyer.
Can the one-month period for challenge be extended?
No. The one-month period provided for by Article R. 211-11 of the French Code of Civil Enforcement Procedures is prescribed on pain of inadmissibility and no provision allows the judge to extend it. The debtor may, however, argue that the period has not started to run where the notification is void because it lacks the particulars required by Article R. 211-3. After the period has expired, the debtor retains the option of bringing, at his or her own cost, an action for recovery of undue payment before the competent court on the merits (Article L. 211-4).
What happens if my bank has attached unattachable sums?
Attachment of sums that are legally unattachable is a substantial irregularity justifying partial or total annulment of the attachment. The debtor must challenge promptly, producing documents establishing the unattachable nature of the funds: payslips, certificates from social security bodies, or bank statements detailing the origin of the payments in. The judge then orders immediate restitution of the sums wrongly taken, with interest for late payment.
Can I obtain damages in the event of an irregular attachment?
Annulment of a saisie-attribution for irregularity gives the debtor a right to compensation for the loss suffered. This loss is assessed in particular by reference to the consequences of the funds being unavailable: bank charges for incidents, commercial loss, or inability to meet significant instalments. The amount of damages is assessed in concreto according to the circumstances of each case. Production of precise evidence of the losses alleged is a condition for the award of this compensation.
Does my challenge automatically suspend the attachment?
The challenge does not deprive the attachment of its assignment effect, but it defers payment of the creditor by the garnishee until the decision dismissing the challenge, unless the judge authorises payment of a sum that the judge determines (Articles L. 211-5 and R. 211-13). The judge gives effect to the attachment for the uncontested portion of the debt (Article R. 211-12). In the case of an attachment of an account, the debtor may request, from the time of the summons, that the unavailability be ended by the provision of an irrevocable guarantee up to the sums claimed (Article R. 211-21), or request the release of an unnecessary or abusive measure (Article L. 121-2).
How can I prove that I have already paid my debt?
Proof of payment may be established by any means: receipts signed by the creditor, bank transfers, correspondence acknowledging receipt of payment, or set-off between reciprocal claims. Production of these documents necessarily accompanies the challenge. In the absence of a formal receipt, proof may result from a body of consistent indications: a bank debit matching the amount of the debt, the absence of any reminder after the alleged payment, or conduct of the creditor that is inconsistent with non-payment.
What should I do if the creditor persists after its attachment has been annulled?
Final annulment of a saisie-attribution prevents the creditor from carrying out a new attachment on the same basis, unless the defects that justified the annulment have been remedied. If the creditor persists with vexatious enforcement after annulment, the debtor may seek damages for abuse of rights and ask for a prohibition on further enforcement on the same basis. Repeated use of irregular procedures may engage the civil liability of the creditor and of its counsel.
Strategic recommendations
Challenging a saisie-attribution effectively requires a prompt and methodical response. Before any court proceedings, analyse precisely the conditions of validity of the attachment and assemble a probative file supporting your grounds of challenge. Producing a structured legal memorandum, accompanied by relevant supporting documents, optimises your chances of success before the enforcement judge.
If the attachment seriously jeopardises your financial situation or that of your business, seek the substitution of an irrevocable guarantee for the unavailability of the account (Article R. 211-21) or the release of an unnecessary or abusive measure (Article L. 121-2), pending the final decision on the challenge.
