A French seizure can be challenged, and a single judge hears the challenge. What decides the outcome is rarely the argument. It is the clock: most enforcement measures carry a deadline of one month or less, and a debtor who misses it is barred for good.

The judge who hears every challenge, and what he may now decide

Every challenge to a French enforcement measure goes before the juge de l’exécution, the enforcement judge usually abbreviated to JEX. Article L. 213-6 of the Code de l’organisation judiciaire gives that judge exclusive jurisdiction. The jurisdiction covers difficulties relating to enforceable titles and disputes arising during forced enforcement.

Exclusive means exclusive. No other French court may rule on the point, and the parties cannot agree to send the dispute elsewhere. The rule matters to a foreign creditor or debtor for a practical reason: a challenge filed before the wrong court is not redirected, it is dismissed.

The scope of that jurisdiction has just widened. Law no. 2026-403 of 26 May 2026 rewrote Article L. 213-6, and the new wording took effect on 28 May 2026. The JEX now hears these disputes even where they bear on the substance of the right, unless the matter falls outside the ordinary courts altogether. The same reform transfers pending proceedings to the JEX automatically, and the parties or their lawyers must be told without delay.

That widening is easy to overstate. Ruling on the substance of the right raised during enforcement is not the same as retrying the judgment behind it. A debtor who lost on the merits does not get a second hearing because a bailiff has since knocked at the door. What the debtor gains is the ability to argue, before the enforcement judge, that the debt has been paid, set off or extinguished by limitation. The institution itself, its territorial rules and its procedure are covered in our guide to the French enforcement judge.

One month to challenge a bank garnishment, and three formalities to get right

A debtor whose bank account has been garnished has one month to challenge the measure. Article R. 211-11 of the Code des procédures civiles d’exécution runs that month from the day the seizure is served on the debtor. Missing the deadline bars the challenge outright.

The month is the visible trap. The formalities around it catch more debtors, because the article imposes three steps and sanctions them differently:

  • file the challenge within one month of service on the debtor;
  • notify the enforcement officer who levied the seizure, the same day or the next working day at the latest, by registered letter with acknowledgement of receipt;
  • lodge a copy of the summons with the registry of the enforcement judge, by the day of the hearing at the latest.

The first two steps carry inadmissibility. The third carries a different sanction: the summons itself lapses. A debtor can therefore file in time, notify in time, and still lose the case on a filing missed at the registry desk. Bank account seizures and their mechanics are set out in our guide to garnishment in France.

One drafting detail is worth flagging to foreign readers. Article R. 211-11 still refers to the huissier de justice. That profession was merged into the commissaire de justice on 1 July 2022, and the code has not been updated on this point. The officer to notify is the commissaire de justice named on the seizure document.

Real-estate foreclosure runs on a different and harsher clock

Foreclosure on French real property follows its own timetable, and the window closes early. Article R. 311-5 of the Code des procédures civiles d’exécution bars any challenge raised after the orientation hearing. The court applies that bar of its own motion, without waiting for the creditor to raise it.

The audience d’orientation, or orientation hearing, is the hearing at which the court decides whether the property will be sold by auction or by private treaty. Everything a debtor wants to argue about the title, the debt or the regularity of the procedure must be argued by then. After that hearing the debtor keeps only a narrow right: where a later procedural document is notified, a challenge to that document may be brought within fifteen days of its notification.

A creditor does not have to plead the bar for it to apply, because the court raises it on its own motion. For a debtor served with a commandement de payer valant saisie, the practical consequence is immediate. Instructing a lawyer after the orientation hearing is usually too late, whatever the merits. The procedure as a whole is described in our guide to foreclosure in France.

Challenging a seizure does not stop it

Filing a challenge before the JEX does not suspend the seizure, and neither does appealing the decision. A debtor who wants the enforcement stopped must apply separately for a stay. Article R. 121-22 of the Code des procédures civiles d’exécution sends that application to the first president of the court of appeal.

The application is made by summons in interim proceedings, served on the other party and, where a third party holds the seized asset, notified to that third party as well. Until the first president rules, the application produces a provisional effect of its own: it suspends the enforcement, provided the decision under appeal had not already called the enforcement into question.

The threshold is deliberately high. A sursis à exécution, or stay of enforcement, is granted only where serious grounds exist for setting aside or varying the decision under appeal. A debtor who applies without such grounds runs a real risk. The first president may impose a civil fine of up to 10 000 euros for a manifestly abusive application, and damages may be claimed on top. The order of the first president cannot be appealed to the Cour de cassation.

Debtors sometimes confuse this stay with the provisional enforcement attached to a first-instance judgment, which is a separate mechanism explained in our guide to provisional enforcement in France.

What a successful challenge delivers: release of the measure, and damages against the creditor

A debtor who wins before the JEX can obtain more than the end of the seizure. Article L. 121-2 of the Code des procédures civiles d’exécution empowers the judge to release any measure that is unnecessary or abusive. The same article allows the judge to order the creditor to pay damages for abusive seizure.

Two distinct grounds sit in that one sentence, and the weaker of the two is the one most often overlooked. Abuse requires proof of the creditor’s conduct. A measure that is merely unnecessary requires no such proof, and a seizure of 40 000 euros to recover 900 euros is unnecessary on its face. A debtor facing a disproportionate measure argues the first ground, not the second, because the first is easier to establish.

The symmetry with the stay procedure is worth holding in mind, since the two provisions point in opposite directions. Article L. 121-2 penalises the creditor who seizes abusively. Article R. 121-22 penalises the debtor who applies abusively for a stay. Both risks are real and they sit on different texts, so a debtor who is advised only of the second has been advised badly.

Deadlines this short leave little room to shop around once a seizure has landed.
