The research method used in this research is descriptive analytical, with a normative juridical approach. This research was conducted by means of library research and field research with data collection techniques through documentation studies and interviews as well as data analysis methods used in this study using qualitative juridical analysis. Based on the results of research and discussion, the following conclusions can be drawn: First, the implementation of the joint venture agreement requires very serious handling and requires professionalism from both parties in order to avoid things that arise from the implementation of the joint venture agreement; Second, the problems that arise in the implementation of the joint venture agreement are due to the distribution of shares of 49% (national) and 51% (foreign) so that foreign companies can make important decisions because the shares are more than half, the distribution of shares is usually small, each only have only 20%, there is a transfer of shares to another party, because of dissatisfaction. The existence of these problems gives rise to investment disputes and efforts that can be made in accordance with the Capital Market Law in the form of dispute resolution by way of deliberation and consensus, arbitration or courts, and specifically for disputes between the government and foreign investors, disputes are resolved through agreed international arbitration.
