<![CDATA[The development of the internet has changed the lifestyle and behavior of the world's people, where information and communication is usually done by using a piece of paper to become electronic. This development does not rule out the possibility that it will also occur in transactions in the business sector. At this time transactions that occur between requests and offers can be easily carried out even though the parties concerned are in different areas because of advances in information technology, which is then called E-Commerce technology. The existence of E-Commerce transactions triggers the development of electronic contracts or e-contracts. Referring to Law Number 11 of 2008 concerning Information and Electronic Transactions (UU ITE), electronic contracts are agreements between parties made through an electronic system. However, the existence of this electronic contract actually raises several legal issues regarding the validity of electronic contracts, such as the difficulty of identifying competence between parties as a result of agreements being made not face to face and the difficulty of determining or proving that the electronic contract was indeed approved by both parties. Thus the author is interested in examining two problems, namely 1) What are the terms, principles and elements contained in the law of the agreement if it is related to the validity of the agreement electronically?, 2) What are the legal consequences of the invalidity of an agreement made electronically? In this study, the authors used the normative juridical research method where normative juridical research is legal research carried out by studying laws and regulations or laws and conducting research based on doctrines that are conceptualized as rules or norms which are guidelines for behavior that are considered appropriate. The type of approach used in this study uses two types of approaches, namely, the statutory approach and the conceptual approach.]]>
