Land management and community engagement are two key components in preventing conflict among native landowners and organizations. Disputes between owners and agencies will be the most difficult impediment to overcome in the land ongoing development. Led to extensive opposition among native customary peoples to native customary land alienation, the government has worked to provide a fair manner of individual ownership for native customary peoples. This point shows how land ownership issues may pose a danger to the nation if they are not addressed in appropriate forms and ways to the native customary community. This paper examines the influence of Communal Grants and land allocation in the Sabah Land Ordinance on native land disputes among Malaysian native landowners. Native landowners from Sabah constituted the population of this study. Samples were chosen using a simple random sampling technique. The gathered 100 complete responses were analyzed using partial least square structural equation modeling (PLS-SEM). The findings revealed that the Communal Grants and land allocation in the Sabah Land Ordinance have significant positive influences on native customary land disputes. This study contributed significantly to the customary land alienation of native peoples as a minority group and indigenous world population.
