Travel documents for minors – Slovakia
Other than their own valid travel document (passport or ID card), no particular extra official authorisation is required by law for minors of any EU country to enter or leave Slovakia.
It is, however, recommended that children travelling to or from Slovakia alone or with an adult other than a parent have the sk of both parents. Similarly if they are travelling with only one parent, the consent of the other parent is advised. The signatures on these declarations should ideally be certified by a notary.
