The member States of the Council of Europe, signatory hereto,
Recognising that in the member States of the Council of Europe the welfare of the child is of overriding importance in reaching decisions concerning his custody;
Considering that the making of arrangements to ensure that decisions concerning the custody of a child can be more widely recognised and enforced will provide greater protection of the welfare of children;
Considering it desirable, with this end in view, to emphasise that the right of access of parents is a normal corollary to the right of custody;
Noting the increasing number of cases where children have been improperly removed across an international frontier and the difficulties of securing adequate solutions to the problems caused by such cases;
Desirous of making suitable provision to enable the custody of children which has been arbitrarily interrupted to be restored;
Convinced of the desirability of making arrangements for this purpose answering to different needs and different circumstances;
Desiring to establish legal co-operation between their authorities,
2.
Any State may at any later date, by a declaration addressed to the Secretary General of the Council of Europe, extend the application of this Convention to any other territory specified in the declaration. In respect of such territory, the Convention shall enter into force on the first day of the month following the expiration of a period of three months after the date of receipt by the Secretary General of such declaration.
