Brazil — Law 12.318/2010 (first explicit Parental Alienation statute worldwide)

TL;DR¶

Brazil enacted the world's first explicit Parental Alienation statute with Law 12.318/2010 (Lei da Alienação Parental). The statute defines alienation, lists examples, gives courts a graduated remedy hierarchy (warning → fine → supervised contact → transfer of custody → suspension of authority), and creates the statutory expert-evaluation mechanism (estudo psicossocial). Operating within the Civil Code 2002 + Child and Adolescent Statute (ECA, 1990) framework. Hague 1980 (2000) + Hague 1996 (2015). Universal post-2010 reference point for PA jurisprudence worldwide.
