Early marriage in Indonesia is one of the problems not only related to marital law (the age limit of marriage), but also related to issues of child protection and human rights. Many factors underlie early marriage, starting from the factors of customs, families, religious views, to the economy. In fact, based on the facts and results of research, early marriage at least provides a social impact, namely the occurrence of divorce, weak family stability, the occurrence of gender discrimination, and parenting to children who are not optimal. This research discusses two important things, namely, first, what is the role of the government in upholding and protecting children's rights in cases of early marriage in Indonesia, and second, what factors influence the enforcement and protection of children's rights in early marriage. This study uses qualitative methods with socio-legal approach by comparing existed cases either through print or online media with relevant laws and regulations. This study confirms that in the case of early marriage, there are at least some children's rights that are violated, namely: (1) the right to education, (2) the right to protection, (3) the right to play and recreation, (4) the right to equality. In the case of early marriage, children are often victims of violence and discrimination. In some cases, early marriage also causes the release of parental responsibility to children.
