UNIÃO ESTÁVEL: O PRINCÍPIO DO INFORMALISMO FRENTE AO ARCABOUÇO JURÍDICO CONTEMPORÂNEO

Abstract

The theme of the research revolves around the legal institute of stable union, inserted within the branch of family law, contained within the scope of Brazilian civil law, in interdisciplinary dialogue with the disciplines of Notary Law and Public Registry Law, aiming to investigate whether the inherent absolute informality persists in the stable union institute in the face of the contemporary legal framework. The underlying hypothesis is that, with legal and jurisprudential changes, the principle of absolute informality does not subsist in the same manner as before, becoming increasingly flexible to the extent of being observed as relative informality. The article outlined its objectives as defining stable union, as well as its brief historical-legislative trajectory, its requirements and legal effects, its methods of declaration and registration, and finally, informality as a consequence of the principle of freedom. The method employed was hypothetical-deductive, and the adopted review approach was indirect bibliographical and documentary. Furthermore, as theoretical foundations, the pillars of legislation, doctrine, and jurisprudence of superior courts were employed.
