Abstract:
The aim of this study was to analyze the principle of affectivity in judgments of the
Superior Court of Justice (STJ), discussing the adoption of Brazilian law in which the
current legislation is a crime. The methodology used is descriptive, seeking to clarify
the vision of the theme used, which is not properly disseminated, but which has great
relevance in society. Through the main results in studies carried out through
principles, it was observed that the judiciary's understanding of the conclusion that
socio-affective paternity is equal to biological paternity, and that once built, it is no
longer disconnected. Thus, an understanding gained little by little in a society full of
prejudice and resistance. Therefore, it appears that the principle of affectivity was the
basis for the decisions of the STJ, given that the principle of the dignity of the human
person as well as the best interest of the child prevailed.
