This study examines the legal validity of marriages among indigenous belief followers in Indonesia and the efforts to secure state recognition for such marriages. In practice, these individuals often face difficulties in obtaining legal acknowledgment due to unclear regulations and limited public understanding. This research employs an empirical juridical method with a sociological and descriptive-analytical approach, combining field data from observations and interviews with primary and secondary legal materials. The findings indicate that indigenous belief marriages can be legitimized if conducted before a leader of the respective belief, in accordance with Article 2 of Law No. 1 of 1974 on Marriage and Government Regulation No. 40 of 2019. After receiving a marriage certificate, followers of indigenous beliefs can register at the civil registry office to obtain an official marriage certificate.
