Widowed women in Bali often experience injustice in the fulfillment of rights and the imposition of responsibilities in social life in traditional villages in Bali. The customary law in force often places widows in a vulnerable position socially, economically, and legally, which has the potential to violate the principle of gender justice as observed in national law and human rights instruments. This study aims to normatively analyze the rights and responsibilities of widowed women in traditional villages in Bali, and to test their conformity with the principle of gender justice. This study uses a normative legal research method with a legislative, conceptual, and comparative legal approach in several traditional villages. The results of the study indicate an imbalance between customary norms and the principle of gender justice, especially regarding ownership rights, social rights, and family and customary responsibilities that are imposed in a discriminatory manner. Therefore, harmonization is needed between customary law and the principle of gender justice within the framework of national law.
