Some children, whose rights have been violated, are referred to the protective modality called the foster family, also known as the foster care. This is a temporary alternative, in which an already constituted family receives, in their residence, children in need of care. The warm family nucleus commits itself to valuing and respecting the individual and cultural particularities of each one. The foster families must contribute to the restoration of affections and fulfillment of fundamental rights, as recommended in the Statute of the Child and Adolescent and the Law on the Protection of Children and Young People. The most important objectives of foster care in families are to protect, ensure family and community coexistence, and to ensure that family reintegration is possible, when possible and safe. Today, in Brazil, the foster care is inserted in a national public policy, as an action to be implemented in the services of Special Social Protection of High Complexity. The services of foster family have great relevance, mainly in this scenario, since they suggest the non-institutionalization, giving character of more directed care. In Portugal, this measure is also contemplated in legislation, however, as in Brazil, it has been developed on a residual basis. This paper is a meeting of scientific articles whose main objective is to think about the challenges and possibilities of family reintegration of children accepted in this modality. Through the survey monkey methodology and the content analysis the data were collected and analyzed in three stages. The results of the research point to the need to increase the reception, better understanding of the phenomenon of reintegration, and reflection on the time of return valuing the singularity of each case. Thus, the improvement of studies and investment in family care must be prioritized both in Portugal and in Brazil, to the detriment of institutionalization practices.
