The guardians of a person aged under 18, who have been entered in the population register, can jointly authorise each other or a person of their choice to manage the minor’s matters on their own if the child does not have a non-disclosure for personal safety reasons.
When the mandates have been granted, the person, company, association or other organisation (the assignee) that received the mandate can, in services that use Suomi.fi e-Authorizations, handle the matters of the person who granted the mandate. You can grant as many mandates as you wish and to as many parties as you wish.
Another person, company, or organisation may also ask you for a mandate for transactions, in which case you grant the mandate by approving a mandate request.
