The present research intends to analyze the practices and discourses that cross the activities of professionals of the justice system who, in the name of integral protection and care, govern and blame the lives of children, adolescents and their impoverished families. Through the method of research-intervention and the experience as a psychologist in a Childhood and Youth Court, it was used the technique of field diary to analyze parts of the case of a family that had their rights violated by members of the family nucleus itself, and by the State. It is important to consider for this analysis the concepts of Institutional Analysis, the works of Michel Foucault and other authors involved in the issue of the guarantee of children and adolescents rights, so that it can be verified the discourses and practices that arise in justice and can promote subtle or devastating right violations against the family group.
