This chapter contains reports on violence and victimization experienced by
children and young people. This chapter addresses complaint procedures to secure the participation rights of children and adolescents in residential group care in Germany and is based on the project “Participation in Residential Childcare” funded by the German Research Foundation (DFG). Different complaint processes in the residential groups will be presented against the backdrop of different idiocultures that were analyzed in residential group care. In addition, a theoretical conceptualization of complaint procedures to secure participation rights will be proposed. The review of the care-experienced person Antonina Milinkovic is presented and linked to the following conclusions. The results are discussed against the backdrop of the international discourse about the implementation of the UN Convention on the Rights of the Child.
