Book excerpt: A practical guide to assist legislators and legal practitioners in facilitating the reunification of refugee and migrant children with their families As a result of the sharp increase in the refugee and migrant population in recent years, many children and their families have experienced family separation. Member states are bound by various obligations related to family reunification, and the practical reunification of refugee and migrant children with their family members has proved complex. This handbook is a practical guide both to key legal standards and to promising practices in the field of family reunification and restoring family links. This publication is conceived as a point of reference for capacity-building material, technical assistance, co-operation projects and new practices for and with relevant authorities and institutions. It focuses on the reunification of families with children in the context of international migration, and in particular on reunification possibilities for unaccompanied and separated refugee and migrant children. It presents an overview of legal principles of human rights, children’s rights, refugee law and EU law relevant to family reunification and then discusses key features of family reunification procedures, with promising examples of law and practice and relevant applicable standards. The handbook contributes to achieving the objectives of the Action Plan on Protecting Refugee and Migrant Children in Europe (2017-2019).
