“Article 15 (1) In exercising their jurisdiction under the provisions of Chapter II, the authorities of the Contracting States shall apply their own law. (2) However, in so far as the protection of the person or the property of the child requires, they may exceptionally apply or take into consideration the law of another State with which the situation has a substantial connection. (3) If the child's habitual residence changes to another Contracting State, the law of that other State governs, from the time of the change, the conditions of application of the measures taken in the State of the former habitual residence.”
“Parental responsibility which exists under the law of the State of the child's habitual residence subsists after a change of that habitual residence to another State.”
