The Department of Foreign Affairs' website outlines some of the particularities those travelling with children should be aware of when travelling abroad. Full details are available at www.dfa.ie/travel/assistance-abroad/childrens-issues/
The Deputy should be aware that each country may have their own requirements for those travelling with children who are not their own.

Airlines and ferry companies may also have their own requirements for those travelling with minors.
