This study aims to examine the legal protection of children born from unregistered marriages under Indonesian law and to analyze its implementation in Namorambe District. It specifically examines the legal provisions governing children’s rights and the fulfillment of their rights to care, custody, financial support, legal identity, and protection. This study employs a qualitative socio-legal approach, combining analysis of relevant legal regulations with empirical data collected through interviews and direct observations in Namorambe District. The findings show that several children experience the consequences of parental separation or divorce, with inadequate marital preparation identified as one contributing factor. The situation becomes more complex when the parents’ marriage is unregistered, as the absence of formal documentation may weaken the practical enforcement of parental responsibilities. Some parents demonstrate limited responsibility after separation, particularly regarding childcare, custody, and financial support, resulting in the inadequate fulfillment of children’s rights. The study concludes that although Indonesian law provides a legal basis for protecting children regardless of their parents’ marital registration status, implementation remains constrained by limited parental responsibility, legal awareness, and access to protection mechanisms. This study contributes to socio-legal scholarship on Indonesian family law by providing empirical insight into the relationship between marriage registration, parental responsibility, and child protection at the local level. It emphasizes the need for stronger legal awareness, institutional protection, and parental accountability to ensure the fulfillment of children’s rights and welfare.
