If you are travelling with someone else’s child or with a child with a different surname, you may have to explain the relationship between you and the child to immigration officers in the country you are travelling to. If you are travelling alone with your child, you may have to provide evidence that you have the other parent’s consent to travel. You can find advice on the type of documentation you should bring with you in these situations on the Irish Naturalisation and Immigration Service (INIS) website.
