Virtual property is one form of development in the law of objects that exist in cyberspace through an internet connection. Although the law has stipulated the conditions for the validity of an agreement that must be fulfilled, in practice sometimes there is a sale and purchase agreement where if viewed from the legal aspect it can be seen that the agreement in question deviates or does not meet the legal requirements of an agreement that is legally binding. stipulated in article 1320 of the Criminal Code Per. This creates a lot of problems for players who make transactions through the trade feature. The existence of this transaction can lead to anonymity in conducting transactions so that it violates the legal conditions in entering into an agreement. With these problems a question arises: How is the validity of the virtual property sale and purchase agreement in online games based on the Criminal Code? What are the legal consequences of anonymity in a virtual property sale and purchase agreement in an online game based on the Criminal Code? This study used a normative juridical approach. The data of this research were collected by literature study and interviews with online game players who felt the consequences of anonymity and the analysis of the data used in this study was qualitative. The results of this study If the elements of the legal requirements for entering into an agreement are fulfilled, then the virtual property agreement in this online game can be said to be valid in terms of making an agreement between the two parties. However, in this agreement, it can happen that the subjective conditions in the agreement do not meet, especially on competence. The legal consequences of anonymity in the virtual property sale and purchase agreement in online games, illustrates that there is one subjective condition that is not fulfilled, then the agreement can be canceled (voidable). As long as the agreement has not been legally canceled by the judge, the agreement remains binding on both parties.
