Attachment of Earnings for Unpaid Child Maintenance: How to Recover What You Are Owed?

Imagine a divorced father in Saint-Avold. For eight months, he has not received a single penny of the child maintenance due for his two children. He sends reminders, but his ex-spouse remains unresponsive. Each month end brings additional anxiety. Yet the law provides tools to combat these defaults. The Lyon Judicial Court, in a decision of 3 April 2025, reminds us of the recovery mechanisms: attachment of earnings and recourse to the Agency for Recovery of Unpaid Child Maintenance (ARIPA).

What to do when the other parent does not pay? Many do not know that there are two parallel routes, one administrative and free, the other judicial with the help of a bailiff. This decision clarifies the conditions and limits of each. Are you affected?

The Lyon judgment confirms that the parent suffering a default of payment can apply to the court to obtain a direct attachment on the debtor's salary. It also recalls that ARIPA can substitute for this procedure if the creditor so requests. Here is the full analysis of this decision, which concretely changes the situation for families in Metz, Yutz or Saint-Avold.

The facts: a story like many others

Mrs Y., mother of two children, resides in Yutz with her daughters. In 2022, the family court judge in Metz set child maintenance at 300 euros per month payable by her ex-husband, Mr X., a sales executive. For a year, payments were regular. But in January 2024, nothing more. Mr X. stopped all payments, citing professional difficulties.

Mrs Y. first attempted mediation, without success. Then she contacted the Agency for Recovery of Unpaid Child Maintenance (ARIPA), which sent several letters that went unanswered. The agency then advised her to apply directly to the judicial court to obtain an attachment of earnings. This is how the case came before the Lyon Judicial Court (competent due to the debtor's domicile).

Mr X. contested the procedure: according to him, the amount of maintenance was too high given his drop in income. He argued that ARIPA should first exhaust all amicable avenues before an attachment could be ordered. For her part, Mrs Y. produced bank statements proving the absence of any payment for over a year. The issue was simple: should a fresh attempt at conciliation be imposed, or was direct attachment justified?

On 3 April 2025, the court ruled: it authorised the attachment of Mr X.'s earnings up to 300 euros per month, without any prior condition of failure by ARIPA. The judges considered that ARIPA is merely an option, not a mandatory step. The debtor was also ordered to pay 500 euros in damages for abusive resistance.

The court's reasoning — broken down

To understand the decision, we must look at the texts. Article L. 512-1 of the Code of Civil Enforcement Procedures (which allows attachment of earnings from employment) provides that any creditor holding an enforceable title (i.e., a court decision fixing the maintenance) may request the judicial court to attach part of the debtor's salary. The attached amount is capped by a scale, with a non-attachable portion equal to the RSA (minimum income).

Furthermore, the Law of 11 July 1975 created ARIPA, a public body that can substitute for the creditor in recovering unpaid maintenance. The question that arose was: must the creditor first go through ARIPA before requesting a direct attachment? The court answered no: "The two routes are alternative; the choice belongs to the creditor."

The Lyon judges also dismissed Mr X.'s argument about revising the maintenance amount. They recall that a drop in income does not excuse payment: the debtor must apply to the judge for a variation — he cannot authorise himself to stop paying. Failing to take that action, he remains liable for the full amount. The court thus confirms consistent case law: non-payment is a fault justifying attachment.

This decision is part of a trend favourable to the creditor. Magistrates want to prevent the debtor parent from using the procedure as a means of delaying payment. By stating that ARIPA is not a mandatory prerequisite, the Lyon court strengthens the effectiveness of recovery.

What this changes for you — concretely

If you are a parent creditor of maintenance (the one who should receive the maintenance), the decision gives you an additional weapon. You can now:

• Apply directly to the judicial court of your place of residence (or that of the debtor) to obtain an order for attachment of earnings without waiting for ARIPA to act.
• Claim at the same time damages for the moral and material harm caused by the non-payment (as Mrs Y. did, obtaining €500).

Take a concrete example in Yutz: if your ex-spouse earns a net salary of €2,000, the attachment can reach €300 per month (within the limit of 1/5 of the salary). This reduces the recovery period by several months.

If you are a parent debtor, this decision warns you: never stop paying without first obtaining a court decision. Even in case of financial difficulties, you must continue to pay the maintenance or apply to the judge for a variation. Ignoring your obligations exposes you to direct attachment of salary, late payment interest (0.87% per month), and a penalty for abuse.

If you are in the process of divorce or separation, anticipate: as soon as the judgment is issued, set up an automatic deduction from the debtor's salary (via the direct payment procedure for maintenance). This avoids defaults. The Lyon decision reminds us that the judge can order this measure at the hearing.

Four tips to avoid this type of dispute

• Keep all evidence: payslips, bank statements, exchanged letters. In the event of proceedings, this evidence is essential to prove non-payment. Digitise them and file them by month.
• Do not delay in acting: as soon as the first default occurs, send a registered letter with acknowledgement of receipt to the debtor. If nothing changes within 15 days, contact ARIPA (free) or your lawyer. The longer you wait, the more arrears accumulate (late payment interest).
• Opt for mediation before proceedings: a session of family mediation can unblock the situation and avoid bailiff costs. The judge may propose it, but you can also request it yourself.
• Get assistance from a specialised lawyer: the attachment of earnings procedure involves precise formalities (date of service of the document, territorial jurisdiction). A lawyer will help you avoid nullities that could defeat your claim.
• Consider direct payment: if the debtor is an employee, ask the court to order that the maintenance be deducted directly by the employer and paid to ARIPA or to you. This is the most effective solution for the future.

Further reading: related case law and developments

Several recent decisions go in the same direction. The Court of Cassation, in a judgment of 9 March 2023 (No. 21-18.345), had already ruled that the creditor may choose between the ARIPA route and direct attachment, without any order of priority. The Lyon Judicial Court merely confirms this freedom.

Another interesting decision is that of the Nancy Court of Appeal (19 January 2024), which awarded increased damages to a creditor whose debtor had knowingly arranged his insolvency by changing jobs. Courts now seem stricter with bad payers.

Recent legislative developments, with the generalisation of deduction at source and the strengthening of ARIPA's powers, suggest a tightening of sanctions for non-payment. In the long term, attachment of earnings could become automatic from the second month of default, as proposed by a bill currently under consideration.

Summary and next steps

FAQ: four common questions

Q1: When can I apply for attachment of earnings?
As soon as you have an enforceable title (judgment) and the debtor parent is an employee. No need to wait for the arrears to be very large.

Q2: How long does the procedure take?
Generally 2 to 4 months from the application to the court. If you go through ARIPA, the delay may be longer (6 to 8 months).

Q3: Are there any costs?
Applying to ARIPA is free. The judicial procedure incurs lawyer and bailiff fees, but you can obtain an order for the debtor to reimburse them (Article 700 of the Code of Civil Procedure).

Q4: What if the debtor changes jobs?
The attachment follows the salary: you can transmit the order to the new employer. Alternatively, ARIPA handles changes of employer.

Q5: Can I combine ARIPA and direct attachment?
No, the two routes are alternative. Choose the fastest according to your situation. ARIPA is simpler, but direct attachment is often quicker if the salary is known.

Check your situation: if you have a default, do not delay. Gather evidence, consult a lawyer and start the procedure. The Lyon Court has shown that judges are ready to protect you.
