Background: Medicolegal services are essential for protecting patients affected by malpractice resulting from misdiagnosis. However, Law Number 17 of 2023 on Health and related regulations do not explicitly require standardized medicolegal units in hospitals, creating legal uncertainty, weak evidence management, and unequal positions between patients and medical professionals. Objective: This study aims to analyze the existing legal protections for patients affected by misdiagnosis, examine the necessity of medicolegal services in hospitals, and formulate a medicolegal service model that ensures legal certainty, proportional protection for patients and healthcare professionals, and justice in medical dispute resolution. Methods: This research employed a normative-empirical legal approach using statutory, conceptual, and comparative methods. Primary data were collected through interviews with medical practitioners, hospital legal officers, and forensic medicine experts, while secondary data were obtained from legislation, legal literature, and relevant academic sources. The data were analyzed qualitatively using a descriptive-analytical approach. Results: The findings reveal that current legal protections for patients remain fragmented and have not been integrated into a comprehensive hospital-based medicolegal system. The absence of mandatory medicolegal units weakens documentation, medical audits, and preliminary clarification processes, thereby reducing the effectiveness of dispute prevention and resolution. Conclusion: A standardized medicolegal service model is needed, supported by stronger legal foundations, clear authority, procedural standards, and the principles of legal certainty and justice, to create fairer and more effective medical dispute resolution.
