A/RES/64/142 164. The confidential nature of the information collected should be respected and systems put in place for safe forwarding and storage of information. Information should only be shared among duly mandated agencies for the purpose of tracing, family reintegration and care. 165. All those engaged in tracing family members or primary legal or customary caregivers should operate within a coordinated system, using standardized forms and mutually compatible procedures, wherever possible. They should ensure that the child and others concerned would not be endangered by their actions. 166. The validity of relationships and the confirmation of the willingness of the child and family members to be reunited must be verified for every child. No action should be taken that may hinder eventual family reintegration, such as adoption, change of name or movement to places far from the family’s likely location, until all tracing efforts have been exhausted. 167. Appropriate records of any placement of a child should be made and kept in a safe and secure manner so that reunification can be facilitated in the future. 23
