The Indonesian traditional local custom known as the Ulayat is a local community right to manage certain surrounded land or water for marine natural resources management. There is recognition that the existence of customary law in Indonesia, especially concerning the fisheries and marine resources management system, is of the important and strategic value of the national effort to support sustainable marine and fisheries resources management. The aims of this research are: to identify the perceptions and aspirations of society toward Local Custom values and the adherence to the prevailing traditional/customary law, and to identify the extent to which opportunities for Local Custom values empowerment can be preserved and utilized in managing the coastal areas in North Lombok. This research uses a case study method (Yin, 2011) and qualitative analysis method. The sampling method is being collected purposively. The research results showed that the perceptions and aspirations of society toward the Local Custom values (called awig-awig) is still very strong and is still being practiced. Society tends to be more convinced that the law enforcement using customary law is more effective and has a strong deterrent effect because there are clear sanctions and prohibitions. It is due in part to distrust of the formal law, which seems arbitrary in pursuing any prosecution. The Local Custom, tradition, and customary law, as well as traditional institutions in North Lombok Regency, have an opportunity to be preserved and further developed by implementing awig-awig.
