Ind. Code § 31-33-8-16
After an investigation by the department that a child is a child in need of services, but before petitioning the juvenile court for a dispositional decree or implementing a program of informal adjustment, the department may enter into a voluntary service referral agreement with the child's parent, guardian, or custodian. Under the terms of the agreement, the parent, guardian, or custodian shall successfully participate in and complete any family or rehabilitative services recommended by the department. If a person who enters into an agreement under this subsection fails to substantially carry out the terms of the agreement the department shall terminate the agreement. The department shall provide notice to the juvenile court of any voluntary service referral agreement entered into under this subsection.
