This normative legal research focuses on the role and integration of customary law within the constitutional frameworks of Indonesia and South Africa. The study aims to understand how customary law has evolved and is currently applied within these countries’ modern legal systems. It employs an analytical descriptive methodology to scrutinize the positive legal norms of customary law and its constitutional incorporation. The research reveals that customary law is a pivotal component in both nations. It serves as a foundational element of statehood and an integral part of the legal systems recognized by their constitutions. In Indonesia, the founding fathers acknowledged customary law as essential to the nation’s identity and diversity. This perspective was further entrenched during the reform era. Similarly, South Africa’s Constitution acknowledges and safeguards customary law, reflecting the Indigenous Peoples’ legal system based on their traditions and customs. However, the study identifies significant challenges in the practical application of customary law. These include conflicts with national positive law, difficulties resolving issues among Indigenous communities, and the complexities of integrating traditional and modern legal systems. These obstacles highlight the necessity for a careful and balanced approach in formulating and implementing regulations related to customary law within the broader context of contemporary law and constitutional provisions. The findings of this research provide essential insights for policymakers and scholars. It underscores the necessity of comprehending the complexities of applying customary law within diverse socio-legal contexts, such as those in Indonesia and South Africa. The study concludes that acknowledging and respecting the unique characteristics of customary law, while addressing its integration challenges, is crucial for its effective implementation in modern legal frameworks.
