In facing the entry into force of the AFTA in the ASEAN region there must be harmonization between the legal systems between each ASEAN member country. If not, difficulties will be faced by each country, when the claim of rights in the form of execution of a decision handed down in a country cannot be carried out in another sovereign country. The purpose of this article is to analyse the formation of cooperation in the field of justice between ASEAN countries as a harmonization of law enforcement among ASEAN countries. The conclusion of this article is to form a law enforcement harmonization formation, considering that the regulation and renewal of the rule of law through codification is very slow, so alternative efforts to fill legal rules are urgent to be done by nationalizing transnational legal norms. These efforts are sought through the process of ratification of transnational rules, so that they become part of national law. The act of ratification to ratify multilateral international agreements into national law and the making of bilateral agreements is expected to be able to become an instrument of harmonizing the law between countries with different legal systems.
