The normative legal method is used in this study. This method compares the legal systems of the top ASEAN countries and other RCEP members. This analysis concludes that ASEAN bankruptcy legislation can be improved by using current systems from other ASEAN and RCEP nations. When faced with bankruptcy, the consistency of regulations is supposed to give legal certainty for corporate actors. This will also provide investors from other countries with a sense of security.
