The Organisation must be informed of any change in your family situation within 30 calendar days via the EDH declaration. All the necessary certificates (birth, marriage, PACS, etc.) must be attached to the document.
In case of change of last name following marriage or divorce, please note that a separate declaration must be filled in to register the new name once the new ID documents have been issued.
More details on the procedure can be found in the admin eGuide.
