This paper considers Family Support as a fundamental right of the child. It examines the relationship between the well-being of the child as the core concept of contemporary legal and welfare systems and family as a vital institution in society for the protection, development and ensuring the overall well-being of the child. Considering the fact that international legal standards recognise that children’s rights are best met in the family environment, the paper analyses what kind of support is being provided to families by the modern societies in the exercising of children’s rights and with what rhetoric and outcomes. Family Support is also considered as a specific, theoretically grounded and empirically tested practical approach to exercising and protecting the rights of the child. Finally, international legal standards are observed in the context of contemporary theory and practice of Family Support, while the conclusion provides the implications of such an approach.
