Civil dispute resolution through litigation often encounters obstacles such as high costs, lengthy procedures, and the potential for prolonged conflict between parties. As an alternative, mediation offers a more efficient, faster, confidential dispute resolution method that emphasizes a win-win solution. However, the effectiveness of mediation largely depends on the legal system governing it. This study aims to comparatively analyze the mediation systems for civil dispute resolution in Indonesia and Singapore as a form of alternative dispute resolution. The research adopts a normative juridical method with a statutory and comparative approach. Based on the findings. In Indonesia, mediation is regulated through Law No. 30 of 1999 and Supreme Court Regulation (PERMA) No. 1 of 2016, functioning as a complementary mechanism to litigation and requiring court endorsement for its outcomes to have legal force. Conversely, Singapore regulates mediation comprehensively through the Mediation Act 2017 and has ratified the Singapore Convention on Mediation 2019, enabling mediated settlements to have immediate enforceability and international recognition. While mediation costs are generally lower in Indonesia, Singapore’s system is more advanced in terms of efficiency, legal enforceability, and global competitiveness.
