How do we know when a child is IN NEED OF CARE AND PROTECTION according to the Children’s Act 38/2005?

Section 150 states that:

1. A child is in need of care and protection if, the child-
   1. has been abandoned or orphaned and is without any visible means of support
   2. displays behaviour which cannot be controlled by the parent or care-giver;
   3. lives or works on the streets or begs for a living;
   4. is addicted to a dependence-producing substance and is without any support to obtain treatment for such dependency;
   5. has been exploited or lives in circumstances that expose the child to exploitation;
   6. lives in or is exposed to circumstances which may seriously harm that child's physical, mental or social well-being;
   7. may be at risk if returned to the custody of the parent, guardian or care-giver of the child as there is reason to believe that he or she will live in or be exposed to circumstances which may seriously harm the physical, mental or social well-being of the child;
   8. is in a state of physical or mental neglect; or
   9. is being maltreated, abused, deliberately neglected or degraded by a parent, a care-giver, a person who has parental responsibilities and rights or a family member of the child or by a person under whose control the child is.
