This Master s dissertation proposes a critical gender perspective study of alimony in Brazilian Civil Law, specifically within Family Law. The research presents feminist legal methodologies to analyze existing legal doctrine, both classical and emerging approaches that consider gender. It explores the historical relationship between women s unpaid care work and Family Law, drawing on Marxist and socialist feminism. Recognizing Brazil s social and racial complexities, the dissertation defines the women most impacted by alimony rights. It then delves into feminist critiques of social reproduction, analyzing its role in challenging the productive/reproductive work divison and understanding the care crisis in neoliberalism. Finally, considering social and family oppressions alongside Social Reproduction Theory s intersectional framework, the dissertation analyzes alimony through a gendered lens, highlighting inconsistencies in Brazilian legal doctrine and jurisprudence. It emphasizes the debate around autonomy versus vulnerability, particularly regarding patrimonial imbalances after marriage dissolution. Additionally, it identifies further gender factors and the potential for incorporating a gender perspective into future alimony legislation.
