2026 Guide: How to Block a Saisie Attribution (Attachment of Bank Balances)

Faced with an attachment of bank account balances (saisie attribution), you are not defenceless. This enforcement procedure, although effective for creditors, can be challenged under certain specific conditions. Whether the aim is to protect the unseizable bank balance, to challenge the regularity of the procedure or to raise a procedural defect, several means of blocking a saisie attribution exist to defend your rights.

Understanding the saisie attribution in order to challenge it

How the saisie attribution works

The saisie attribution allows a creditor holding an enforceable title to freeze immediately the sums held in your bank account. The procedure is carried out in the hands of a garnishee (tiers saisi, your bank), which becomes debtor of the seized sums to the seizing creditor.

The effectiveness of this measure lies in its immediate effect: as soon as the notice of seizure is served, your bank must freeze the available funds, up to the amount of the debt plus enforcement costs.

The conditions of validity to check

For a saisie attribution to be valid, several conditions must be met:

• The creditor holds an enforceable title
• A prior order to pay (commandement de payer) has been served and has remained unsuccessful
• The forms and time limits prescribed by law have been complied with
• The debt is liquidated, certain and due

Checking these elements is often the first line of challenge in a strategy of challenging the seizure.

The grounds for opposing a saisie attribution

Opposition for procedural irregularity

An opposition to the seizure may be based on several procedural irregularities. The most frequent formal defects concern:

• Defective service of the notice of seizure
• The absence of a mandatory statement in the bailiff's document (acte d'huissier)
• Failure to observe the period between the order to pay and the seizure
• The bailiff's lack of territorial jurisdiction

These irregularities, if they are substantial, may result in the nullity of the seizure and therefore its blocking.

Challenging the debt on the merits

Even where an enforceable title exists, you retain the right to challenge the existence or the amount of the debt. This challenge may concern:

• Extinction of the debt by payment
• Limitation of the debt (prescription)
• An error in the amount claimed
• Set-off against a reciprocal debt

This remedy often requires the production of probative supporting documents to prove your allegations.

Relying on the unseizable bank balance

The law protects a minimum amount in your bank account, equivalent to the flat-rate amount of the RSA (active solidarity income) for a single person. This unseizable bank balance (solde bancaire insaisissable, SBI) must be released by the bank within fifteen days following the seizure.

If your bank has not complied with this obligation or if it has seized sums beyond what was legally possible, you may obtain a partial release of the seizure (mainlevée).

The available challenge procedures

The opposition procedure before the enforcement judge

The opposition is the main remedy against a saisie attribution. This procedure must be started within one month of service of the notice of seizure.

The application must be lodged with the registry of the judicial court (tribunal judiciaire) of the place where the debtor lives. It must set out precisely the grounds relied on and be accompanied by the necessary supporting documents.

The enforcement judge (juge de l'exécution) has extensive powers: the judge may order the full or partial release of the seizure, grant time to pay, or authorise the payment of certain priority debts.

The request for an amicable release

Before starting court proceedings, it may be worthwhile to attempt a negotiation with the seizing creditor. This amicable approach may result in:

• A payment schedule for the debt
• A partial reduction of the amount claimed
• Immediate release against payment of a negotiated sum

This solution has the advantage of speed and avoids additional procedural costs.

Summary proceedings and urgent measures

In a case of established urgency, in particular where the seizure seriously jeopardises your living conditions, you may apply to the judge in summary proceedings (juge des référés). This accelerated procedure makes it possible to obtain quickly a provisional suspension of the effects of the seizure.

The conditions for summary proceedings are strict: it is necessary to show urgency and the existence of a manifestly unlawful disturbance or of imminent harm.

Preventive strategies and protection of assets

The declaration of unseizability

Certain assets and income benefit from legal protection against seizure. It is essential to know these protections in order to organise one's defence better:

• Family benefits and social allowances
• Salaries within certain limits
• Movable property necessary for everyday life
• Tools essential to professional activity

Declaring these items when bringing the challenge significantly strengthens your position.

Anticipating financial difficulties

Forward-looking management of financial difficulties often makes it possible to avoid seizures or to limit their effects. Amicable over-indebtedness procedures, preventive negotiation with creditors, and debt restructuring are all effective preventive tools.

Spreading funds across several bank accounts

Spreading assets across several banks limits the impact of a saisie attribution. This strategy, which is perfectly lawful, preserves part of the funds needed for everyday expenses.

The consequences of successfully blocking a seizure

The effects of the release

When your opposition to the seizure succeeds, several positive consequences follow:

• Immediate release of the sums wrongly seized
• The possibility of obtaining damages in the event of an abusive seizure
• The procedural costs being borne by the creditor
• Restoration of your normal financial capacity

Recovering the sums paid

If sums have already been paid to the creditor before the seizure was set aside, their return must be obtained. This recovery may require separate proceedings if the creditor does not repay spontaneously.

Preventing repeat seizures

A seizure set aside for a procedural defect does not prevent the creditor from starting again in compliance with the legal forms. This possibility should therefore be anticipated and an overall defensive strategy prepared.

Practical advice to maximise your chances of success

Building the file

A solid challenge file rests on complete and organised documentation. Gather all relevant items:

• The procedural documents received
• Proof of payment or of extinction of the debt
• Bank statements showing the infringement of the SBI
• The correspondence exchanged with the creditor

The time limits that must be observed

The challenge to the seizure is subject to strict time limits which must be observed scrupulously. The one-month opposition period runs from service of the notice of seizure. This period is a clear period (délai franc) and admits no extension.

Particular care must be taken over how these periods are calculated, in particular where service is made electronically or on a third party.

Legal assistance in enforcement matters

The complexity of enforcement procedures often justifies instructing counsel with a particular focus on this area. An experienced lawyer in enforcement law will be able to identify the most relevant grounds of challenge and maximise your chances of success.

This assistance is all the more advisable where the financial stakes are high or where the legal situation presents technical particularities.

Blocking a saisie attribution requires a quick and methodical reaction. Between analysing procedural defects, checking that your rights have been respected and starting the appropriate remedies, each situation calls for a tailored approach. Do not hesitate to seek the help of a legal professional to assess precisely your chances of success and to implement the strategy best suited to your situation. A well-conducted challenge can not only unblock your accounts, but also protect you lastingly against abusive recovery attempts.
