The Committee for the Rights of the Child (CDENF) finalised the implementation review of the Recommendation CM/Rec(2019)11 on effective guardianship for unaccompanied and separated children in the context of migration and published the report after presenting it to the Committee of Ministers during its 1519th meeting on 12-13 February 2025.  Adopted at the CDENF plenary meeting in December 2024, the report is based on the replies to a questionnaire by member states and includes references to consultations with children and young people who have experienced the guardianship system. A full report on these consultations is also appended to the implementation review report. The implementation review highlights that one of the main challenges reported by countries is the diversity of guardianship models and of legal nature or names given to the guardians, both between and within countries. The analysis also shows that all guardianship models have the potential to comply with the Recommendation as long as they comprehensively address all situations in which children may find themselves, regardless of their age or residence status, incorporating a child rights-based approach.
