A DEGIRO investment account may only be managed by the person to whom the account is registered. This means that you cannot issue a power of attorney (POA) for your account. This is described in our Client Agreement.
An exception to this is when a client passes away. Their heir(s) or an attorney can contact our Service Desk to arrange the transfer of the assets. Please see our FAQ about this subject for more information: "What to do in the event of the passing of a DEGIRO account holder."
