The presence of a leader in a traditional community is needed in carrying out its activities as a protector of its citizens. This study aims to find out the dispute resolution process carried out by Karampuang traditional leaders with the power of customary law and also to know the authority of the Pabbatang Karampuang customary institution in resolving disputes. The research was conducted in April-June 2021 in Sinjai District, South Sulawesi Province, Indonesia. The data collection technique was to conduct interviews with the customary stakeholders, religious leaders and the Karampuang indigenous people who were chosen purposive and the library research method. Data analysis used was descriptive analysis. The results of the study show that the conflict resolution process in the Karampuang tradition is handed over to four traditional leaders with different roles who must remain unified and decide all disputes/problems over a joint agreement that cannot be changed anymore. In addition, the authority of the Pabbatang Karampuang Customary Institution in resolving disputes within the community is still divided according to responsibilities. The existence of legal power owned by customary institutions, even though it is not written, is still obeyed by the community.
