Due to the increasingly globalized nature of society, there is an increasing number of children with parents who have a different nationalities. If the family breaks apart, there is a tendency for one parent to flee with their children abroad or go back to the home country. If there is an unlawful movement of a child from one EU Member State to another, the provisions of the Brussels IIa Regulation and the Hague Convention apply. In delicate legal matters, such as parental child abduction, it is important to act swiftly. The Brussel IIa Regulation gives the courts in the former state of residence the power to act quickly to ensure the immediate return of the child. The Regulation provides a two-lane system for the recognition and enforcement of a return decision. On one hand, the return decision needs not be recognised and declared enforceable in the other Member State. On the other hand, there are exceptions where the Regulation dispenses with this procedure and describes no need for a declaration of enforceability. In this thesis, these two types of repatriation of a child are illuminated, with a focus on the rules for the protection of the child.
