Any natural person, whether they reside in Luxembourg or not, and who:

• is of legal age;
• is appointed guardian of an individual through a decision by a Luxembourg court; and
• has a 13-digit Luxembourg national identification number (Matricule).

In cases of guardianship of a minor, a digital power of attorney cannot be created even if the person has reached the minimum age to use MyGuichet.lu.

To create a digital power of attorney you must have your own private eSpace on MyGuichet.lu.

When creating a private eSpace, a unique identifier, known as the eSpace identifier (also commonly referred to as the 'ID' or 'Espace-ID' in Luxembourgish) is assigned to each private eSpace. You must indicate the identifier of your eSpace when setting up the power of attorney.

Creating a power of attorney

As a guardian, you may only create a digital power of attorney for the person under your guardianship in person, at the Guichet.lu reception desk.

You can book an appointment in advance (see 'Online services and forms › Appointment booking'). The person under your guardianship does not need to go with you to the Guichet.lu reception desk.

When creating the power of attorney in person, you must provide the following information:

• about yourself:
  • your surname and first name;
  • your date and place of birth;
  • your 13-digit Luxembourg national identification number (Matricule);
  • the identifier of your private eSpace; and
• about the person under your guardianship:
  • their surname and first name;
  • their date and place of birth;
  • their national identification number (Matricule).

You must also have the following documents with you:

• your identity card;
• a copy of the identity card of the person under your guardianship;
• the original copy of the guardianship order.

The staff member at the Guichet.lu reception desk will be able to use this information to create the digital power of attorney for you.

You will then receive an email notifying you that you have received a power of attorney. This email will automatically be sent to the email address you entered in your private eSpace.

Acceptance and cancellation of a power of attorney

Expiry and renewal

The digital power of attorney on MyGuichet.lu automatically expires at the end date of the period of validity. If you wish to renew the power of attorney, you must create a new power of attorney at the Guichet.lu reception desk.

Ongoing procedures eligible for the power of attorney

Procedures that you have not submitted before the expiry of the power of attorney are saved in the private eSpace of the person under your guardianship. After the power of attorney is renewed, you can resume the procedures without losing the information that was already entered.

If a government department is still processing certain procedures when the power of attorney expires, you can continue these procedures after renewing the power of attorney.  

Journal of powers of attorney

In the journal of powers of attorney (see 'Online services and forms') on MyGuichet.lu, you can:

• view the list of people whose private eSpaces you currently have access to (i.e. active powers of attorney);
• view all powers of attorney that have been rejected or cancelled, or that have expired;
• download proof of power of attorney for:
  • the active power of attorney that authorises you to access the private eSpace of the person under your guardianship;
  • the powers of attorney that have expired or been cancelled.

Proof of power of attorney

Proof of power of attorney is an official document that:

• certifies that you are authorised to act on behalf of the person under your guardianship; and
• is valid only for administrative procedures completed under the digital power of attorney on MyGuichet.lu;
• cannot be used to prove power of attorney outside of MyGuichet.lu (e.g. in person at a government department or at a bank).

The proof of power of attorney contains a GouvCheck QR code that can be used to verify the authenticity of an official document issued in Luxembourg, free of charge and in real time.
