The West Nusa Tenggara Subnational Regulation No. 5/2021 on the Prevention of Child Marriage establishes a comprehensive framework to address child marriage at the provincial level. It includes the creation of a special task force for complaints and assistance, provisions for investigations, awards, monitoring, evaluation, and financing. The regulation also strengthens children's participation through peer counselors, Youth Posyandu, and formal mechanisms for adolescent involvement, while empowering Children's Forums as pioneers and reporters. Additionally, it emphasizes transforming values, norms, and cultural practices that contribute to child marriage.
