This study aims to find out, in detail and in depth, the occurrence of the phenomenon of early marriage even though it is against the law in Indonesia, especially in eastern Java. In addition, this study was also conducted to explain the mechanisms used by religious believers to navigate the complex interactions between their beliefs and legal mandates, as well as to explore the impacts that occur in the context of education, economy, and social life. This research utilizes a descriptive qualitative method that aims to provide a comprehensive and detailed picture of the phenomenon of early marriage. Data were collected from 50 representative members of communities in which early marriage is still practiced in eastern Java. To collect data, observations and interviews were conducted with participants who met the predetermined criteria and through the snowball sampling method. The result of this study is that the phenomenon of early marriage occurs due to inaccessible education, low community welfare, teenage interactions facilitated by social media, and religious factors. Early marriage is often done by getting married religiously first, then trying to get legal status by appealing in a religious court. The impacts of this phenomenon can vary depending on the specific circumstances and cultural context. These include economic dependence on the spouse or family, making it difficult for individuals to support themselves and access educational resources, such as tuition and school materials.
