Purpose: This study examines the normative adequacy and institutional connectedness of Indonesia’s legal framework for protecting child–parent relationships and reconstructs the available legal mechanisms into the Rapid Child Relationship Protection Model (RCRPM). Research Design and Methodology: The study employs normative legal research using statutory, conceptual, limited comparative, and interdisciplinary approaches. Legal materials were purposively selected and verified against authoritative sources, then analyzed through legal mapping, gap identification, authority and limitation verification, and legal reconstruction. Findings and Discussion: The findings show that Indonesian law already provides relevant building blocks, including children’s rights, parental responsibilities, contact rights, special protection, institutional coordination, and monitoring. However, these elements are not explicitly integrated into a continuous pathway for progressively developing relational risks. RCRPM reconstructs them into six stages: early identification, multidisciplinary assessment, immediate protective measures, relationship restoration, integrated institutional governance, and continuous monitoring. Its contribution lies in proposing relational neglect as an analytical and doctrinal lens and integrating existing functions without creating new substantive rights or institutional authority. Implications: RCRPM provides a preventive, coordinated, and sustainable legal framework, while future research should assess its institutional feasibility, implementation, and effectiveness empirically.
