In the legislation of family litigation, we should act in accordance with the consistency of highlighting the authority and the supervision right of the Constitution， learn from the experience of overseas procuratorial organs participating in family litigation， take advantage of the traditional advantages and current good development trends of procuratorial organs， and bring into play the professional expertise of the procuratorial organs to protect public interests. To introduce procuratorial power into family litigation legislation， it is necessary to establish the principle of procuratorial organs supervising family litigation in accordance with the law. Procuratorial organs can exercise supervision power comprehensively， legally， modestly， and honestly， focusing on whether the protection of rights of vulnerable parties has been implemented. In the legislation of family litigation， the procuratorial organ should be endowed with the litigation status of the principal party， to lodge a complaint as a plaintiff or to be notified by the court to participate in the litigation as a defender according to the requirement of special cases. Additionally， in the legislation of family litigation， the procuratorial organs should be endowed with the litigation status of the secondary party， on the basis of real demand， to participate in the litigation lodged by others and express their opinions in court. Based on the reality of the lack of professionals required for family litigation， procuratorial power can be appropriately extended， with procurators acting as assistants and investigators in family litigation.
