AbstractCustomary inheritance law in Indonesia consists of unique and specific patterns that describe the values of traditional Indonesian society that are based on collective and communal culture. There are three types of customary inheritance system: patrilineal, matrilineal, and parental. Every system has a uniqueness that makes it different with others. These differences often cause disputes and problems. The problems are related especially to the status of men and women in relation to patriarchal and matriarchal systems. Settlement of inheritance is done through discussion, approval, or legal remedies. Judges decisions indicate that there is a renewal on the customary inheritance system in which men and women have equal opportunities to become inheritors of their parents. Abstrak Hukum waris adat di Indonesia terdiri dari pola unik dan spesifik yang menggambarkan nilai-nilai masyarakat tradisional Indonesia berdasarkan budaya kolektif dan komunal.
