This comparative report explores the key features of guardianship systems put in place to cater for the needs of all children requiring such protection and those at risk of becoming victims of trafficking or of other forms of exploitation. In this way, the report looks at how existing guardianship systems for children deprived of parental care respond to the particular needs and vulnerabilities of presumed or identified child victims, or children at risk of trafficking and exploitation, such as unaccompanied children. It aims to assist EU Member States to understand better the strengths and weaknesses of their national system.
