The change of children's supervision right should be brought to the court.
 Legal procedures for change of guardianship: first, the existing guardians cannot perform or fail to perform their guardianship duties, or infringe upon the legal rights and interests of the ward, which is the prerequisite for changing the guardianship of children;
 Secondly, someone needs to file a lawsuit to change the child's guardian, including the child's parents, grandparents who have raised the child for a long time, etc. They must be close relatives or organizations living with the child;
 Finally, according to the specific situation, the court made a judgment to change the custody of children from the principle of being conducive to the physical and mental growth of children.
 The application for change of child custody can only be made through the court. In real life, the custody of children is a complex issue, and the relevant laws have no clear provisions.
 Therefore, if you want to change the guardianship of children after divorce, in addition to the existing guardians who are objectively unable to perform their guardianship obligations, you must do a good job in collecting evidence that the existing guardians are detrimental to the growth of children, which is the key to obtaining the change of child guardianship litigation.
