(17)In order to ensure the timely online formation of a company or online registration of a branch, Member States should not make that formation or registration conditional on obtaining any licence or authorisation before that formation or registration can be completed, unless national law so provides for the purpose of ensuring that there is a proper oversight of certain activities. After formation or registration, national law should govern the situations in which companies or branches are not allowed to carry out certain activities without obtaining a licence or authorisation.
