Agent: managing MyGuichet.lu procedures on behalf of another person
Last update
Summary:
If you know someone, such as a member of your family or a close friend, who needs help completing online procedures on MyGuichet.lu, you can, with their consent, create what is known as a 'digital power of attorney'.
This power of attorney allows you to log on to MyGuichet.lu with your own authentication product (e.g. your LuxTrust product) in order to access someone else's private eSpace. This will allow you to complete online administrative procedures on their behalf. You thus assume the role of agent and the other person assumes the role of principal.
This text explains how you, as the agent, can create a digital power of attorney so you can complete online administrative procedures through MyGuichet.lu on behalf of another person.
If a person has been placed under guardianship in Luxembourg, the procedure for setting up a digital power of attorney is different. If this is your case, please consult our dedicated information page on this subject:
Who is concerned
Any natural person, whether they reside in Luxembourg or not, and who:
- is of legal age; and
- has a 13-digit Luxembourg national identification number (Matricule).
The digital power of attorney is not available for emancipated minors. They cannot entrust another person with managing their online procedures on MyGuichet.lu, nor can they carry out online procedures in the name of another person.
Depending on their role, certain restrictions apply to the principal and the agent.
- Principal
- Agent
The digital power of attorney is currently not available to:
- people placed under guardianship abroad;
- people placed under curatorship (whether in Luxembourg or abroad).
However, it is possible to create a digital power of attorney in order to carry out online procedures via MyGuichet.lu in the name of a person placed under guardianship in Luxembourg. If this is your case, please consult our dedicated information page on this subject:
People under guardianship or curatorship (whether in Luxembourg or abroad) can never carry out online procedures in the name of another person.
| Principal | Agent | |
|---|---|---|
| Competent adult | Yes | Yes |
| Emancipated minor | No | No |
| Person under guardianship in Luxembourg | Yes | No |
| Person under guardianship abroad | No | No |
| Person under curatorship | No | No |
Preliminary steps
Setting up a private eSpace
Before setting up a digital power of attorney, both parties (i.e. the principal and the agent) must ensure they each have a private eSpace on MyGuichet.lu.
To create an eSpace, each one must have their own authentication product, i.e.:
- a LuxTrust product;
- a Luxembourg electronic identity card (eID); or
- an eIDAS-compliant means of authentication from another European country.
When creating a private eSpace, a unique identifier, known as eSpace identifier (also called 'ID' or 'Espace-ID' in Luxembourgish) is assigned to each private eSpace. The eSpace identifiers of both parties must be indicat-ed when the power of attorney is created.
Frequently asked questions
In the event of a problem with a LuxTrust product (e.g. forgotten password or product activation issues), please search the LuxTrust help section first, and where needed, contact LuxTrust's client service directly.
- The principal already has a MyGuichet.lu account but is no longer able to log in.
- The principal has never used MyGuichet.lu and would like to create their MyGuichet.lu account.
The person for whom you would like to complete online procedures (i.e. the principal) is in the following situation: they created a MyGuichet.lu account a long time ago. However, they can no longer log in, for example because the authentication product they were using at the time no longer works or is no longer supported. They therefore have a private eSpace but cannot view the identifier assigned to it. In this situation, they can submit a request to receive the identifier of their eSpace.
They can submit this request:
- to the Guichet.lu Helpdesk using the contact form;
- in person at the Guichet.lu reception desk.
In their request, they must:
- state that they can no longer access their private eSpace and that they need the identifier of their eSpace so they can create a digital power of attorney;
- provide:
- their 13-digit Luxembourg national identification number (Matricule); and
- the email address the identifier should be sent to.
So their request can be processed, they must also prove their identity by showing a valid ID document:
- for a request submitted through the contact form, the Helpdesk will contact them so they can send a scanned copy;
- for a request submitted in person, they must show their ID document at the reception desk.
After their request is processed, they will receive the identifier by email.
Even if they are submitting their request in person at the Guichet.lu reception desk, they will not receive the eSpace identifier right away. They must provide an email address to which the identifier will be sent after the request is processed.
You can also submit the request for the person on whose behalf you wish to complete online procedures. In that case, you must send a copy of their ID document to the Helpdesk or show it at the Guichet.lu reception desk.
In addition to our help pages, we provide tutorials featuring screenshots that guide you step by step through the process of registering on MyGuichet.lu and creating your private eSpace.
If the person for whom you wish to complete online procedures (i.e. the principal) is unable to create a private eSpace using the guides, they can always:
- contact the Guichet.lu Helpdesk by phone on (+352) 247 82 000 between 8.00 and 18.00 on working days;
- visit the Guichet.lu reception desk.
Before contacting the Helpdesk or travelling to the Guichet.lu reception desk, they should make sure they have one of the authentication products listed above. Their product must be operational (i.e. they must have activated it and must know their login details) so our teams can help them create their private eSpace.
Deadlines
You can create a digital power of attorney for a minimum duration of one month and a maximum duration of 12 months.
No reminder will be sent prior to the expiry of the digital power of attorney.
- Effective date
- Expiry date
Creating the power of attorney alone will not allow you to complete online procedures on behalf of the other person. If you, as the agent, create the power of attorney, the other person must first accept the request in order for the power of attorney to take effect.
The effective date therefore corresponds to the date on which your principal accepts the power of attorney.
You cannot select an effective date that is in the future.
The expiry date is always calculated:
- starting from the date on which the power of attorney is created, not from the effective date;
- based on the validity period selected when the power of attorney was created.
The person who creates the power of attorney – whether that is the principal or the agent – can choose the validity period.
As an agent, you:
- cannot change the validity period;
- can cancel the power of attorney at any time.
Your principal will receive an email notification (and a push notification if they use the MyGuichet.lu mobile app) if you cancel the power of attorney.
Your principal may, at any time:
- change the validity period, in accordance with the minimum and maximum duration of the power of attorney;
- cancel the power of attorney.
They can perform both of these actions:
- online through their MyGuichet.lu private eSpace;
- in person at the Guichet.lu reception desk.
You will receive an email notification (and a push notification if you use the MyGuichet.lu mobile app) if your principal changes the validity period or cancels the power of attorney.
| Principal | Agent | |
|---|---|---|
| Selection of the validity period during creation | Yes | Yes |
| Subsequent change of the validity period | Yes | No |
| Cancellation of the digital power of attorney | Yes | Yes |
How to proceed
Scope of the power of attorney and legal liability
The digital power of attorney on MyGuichet.lu is a generic power of attorney. Further details on the scope and legal liability can be found under guichet.lu/digital-power-of-attorney.
Creating a power of attorney
The person for whom you wish to complete online procedures may create the power of attorney themselves or ask you to do it.
Below you will find instructions on how to create the digital power of attorney as an agent. If the other person prefers to create the power of attorney themselves, they can find all the information they need in the explanatory text for principals:
As the agent, you can create the digital power of attorney:
- online through MyGuichet.lu; or
- in person at the Guichet.lu reception desk.
- MyGuichet.lu
- Guichet.lu reception desk
To create the digital power of attorney through MyGuichet.lu (see 'Online services and forms'), you need the following information about the person for whom you wish to complete online procedures:
- their 13-digit Luxembourg national identification number (Matricule); and
- the identifier of their private eSpace.
Please also view our tutorial that features screenshots and guides you step by step through the process of creating a digital power of attorney if you are the agent.
To create the digital power of attorney in person at the Guichet.lu reception desk, you do not need to make an appointment. The person for whom you wish to complete online procedures 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 for whom you wish to complete online procedures:
- their surname and first name;
- their date and place of birth;
- their national identification number (Matricule);
- the identifier of their private eSpace.
You must also have the following documents with you:
- your identity card;
- a copy of the identity card of the person for whom you wish to complete online procedures.
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.
Whichever method you use to create the digital power of attorney, the person for whom you wish to complete online procedures will receive an email notifying them that they have been sent a power of attorney. This email will automatically be sent to the email address your principal entered in their private eSpace.
Acceptance of a power of attorney
Creating the power of attorney alone will not allow you to complete online procedures on behalf of the other person. They must first accept the request through their private eSpace on MyGuichet.lu in order for the power of attorney to take effect.
You will receive an email notification (and a push notification if you use the MyGuichet.lu mobile app) when the principal has accepted the power of attorney.
After the principal accepts the request, the digital power of attorney will remain active during its validity period.
Rejection and cancellation of the power of attorney
- Rejection
- Cancellation
If the other person does not want you to be able to complete online procedures on their behalf and does not want to serve as your principal, they can reject the request in their private eSpace on MyGuichet.lu.
You will receive an email notification (and a push notification if you use the MyGuichet.lu mobile app) if the other person rejects the power of attorney.
Once they reject the request, the same request cannot be re-sent. To try again, you must create a new power of attorney, either through MyGuichet.lu or in person at the Guichet.lu reception desk.
Both parties can cancel the digital power of attorney at any time. Additional information about cancellation is available under 'Deadlines › Expiry date'.
Expiry and extension
- Expiry
- Extension
If the digital power of attorney is not extended or renewed, it will automatically expire at the end of the validi-ty period selected during its creation.
No reminder will be sent prior to the expiry of the digital power of attorney.
If the initial duration of the power of attorney was set at less than one year, only your principal can extend the power of attorney by changing the validity period:
- provided that this change is made before the expiry date; and
- in accordance with the minimum and maximum duration of the power of attorney, which is always calculated starting from the initial date of creation.
The total duration of a power of attorney may never exceed one year.
As the agent, you cannot extend the power of attorney.
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 (either on MyGuichet.lu or at the Guichet.lu reception desk).
Good to know
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 your principal's private eSpace. After the power of attorney is extended or renewed, you can resume the procedures without losing the information that was already entered.
If there are procedures the government department is still processing when the power of attorney expires:
- your principal can continue the procedures on their own; or
- one of the 2 parties can renew the power of attorney so you can continue.
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 all the active powers of attorney that authorise you to access someone else's private eSpace.
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 your principal; 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.
