The legal instruments forming the Common European Asylum System (CEAS) foresee the obligation for Member States to start tracing the family members of unaccompanied children who may be in need of international protection when it is in their best interest. As a consequence, EASO held a series of expert meetings on family tracing between 2013 and 2015. As part of this exercise, a mapping of EU+ States’ policies and practices with regard to family tracing has been conducted. The findings from this consultation showed a diversity of practice among EU+ countries. The practical guide will provide a set of reference and guidance materials on family tracing, as well as a mapping of the current state of play in the EU+ States.
