Traditional villages with their customary law have a strategic role in handling Covid-19 starting from managing their territory to distributing social assistance. Through traditional village institutions, the Bali Provincial Government uses local wisdom in increasing community participation and institutions to be actively involved in handling activities and overcoming the impact of Covid-19. This study aims to determine the role of customary law to support government policies in handling Covid-19 in Bali. This study is a descriptive study in which the method used is a normative legal research method, using a statutory approach, a historical approach, a conceptual approach, a philosophical approach, and a case approach.
