On May 20, 2024, IJRS officially joined the 18 Coalition, a coalition that focuses on policy advocacy on the issue of child marriage in Indonesia. IJRS has also held an initial meeting to discuss future collaboration plans to oversee court practices in adjudicating marriage dispensation applications and other advocacy. We hope that the involvement of IJRS in the 18 Coalition can contribute to evidence-based advocacy for the prevention and handling of child marriage in Indonesia.
