What triggers the initiation of an adoption process before a court hearing?

Adoption is a legal process that grants parental rights and responsibilities to individuals who are not biologically related to the child. In order to initiate an adoption process before a court hearing, a petition to terminate parental rights (TPR) must be filed with legal sufficiency. This means that the petition must contain all the necessary information and evidence to support the termination of parental rights. The other options, while important in the adoption process, do not necessarily trigger the initiation of an adoption before a court hearing. Reviewing the social study report, completing a case plan, and conducting a judicial review are all important steps that occur at different stages of the adoption process, but they do not necessarily lead to the initiation of the adoption before a court hearing. Therefore, the correct answer is A filing a petition to TPR with legal sufficiency.
