Can I appeal a Luxembourg district court civil judgment if I missed the deadline by 5 days?

In Luxembourg
Last Updated: Feb 23, 2026
I received the written judgment last week but I only realised the appeal time limit after it had passed. Is there any way to ask for an extension or reinstatement due to a genuine mistake, and what documents would I need?

I understand your concern; missing a legal deadline by just a few days can be incredibly stressful, especially when it involves a court judgment.


In Luxembourg, the law is generally strict regarding appeal deadlines, but there is a specific legal mechanism designed for situations exactly like yours.


1. The "Relevé de Déchéance" (Relief from Forfeiture)


Under the Law of 22 December 1986, you can petition the court for a "relevé de déchéance". This is a procedure that allows a party who has missed a mandatory deadline (like an appeal period) to be "relieved" of that mistake and have their right to appeal reinstated.


 

 


To be successful, you must demonstrate that you were unable to act within the deadline due to an "excusable cause" or circumstances beyond your control.




  • A "Genuine Mistake": Simply forgetting the date is rarely enough. However, if the mistake was caused by a legitimate misunderstanding of the notification, a medical emergency, or a failure in the delivery of the judgment, the court is more likely to grant the extension.




  • The 5-Day Window: Missing the deadline by only 5 days is actually a point in your favor, as it shows you acted "as soon as possible" once you realized the error.




2. Time Limits for the Request


You must act quickly. The request for relief must typically be filed within 15 days from the moment the "obstacle" (your mistake or lack of knowledge) ceased to exist. Since you realized the mistake "last week," your window to file this request is currently open but closing fast.


3. Necessary Documents


To file for a relevé de déchéance, you will generally need to provide:




  • A formal Petition: A written request to the President of the District Court (Tribunal d'arrondissement) or the Court of Appeal, explaining why you missed the deadline.




  • Proof of the "Excusable Cause": If you were ill, a medical certificate; if there was a postal issue, the envelope with the postmark; if it was a technical legal error, a detailed explanation of the confusion.




  • The Original Judgment: A copy of the written judgment you received.




  • Evidence of Diligence: Proof of the date you actually "realized" the mistake (e.g., an email to a lawyer or a timestamped note).




4. Can you appeal a District Court Civil Judgment?


Yes, civil judgments from a Luxembourg District Court are generally appealable to the Court of Appeal (Cour d'appel), provided the value of the claim exceeds €2,000.


 

 




  • Standard Deadline: Usually 40 days from the date of formal service (signification) by a bailiff.




  • Requirement: In Luxembourg, you must be represented by a qualified lawyer (Avocat à la Cour) to file an appeal in the District Court or Court of Appeal.






Next Step


Because the 15-day window for the relevé de déchéance is so short, your most critical next step is to contact a Luxembourg Avocat à la Cour immediately. Only they can file the petition for you.
