Ind. Code § 31-34-21-0.2
At a child's first periodic case review occurring after June 30, 1998, the local office is required to advise the child's parent, guardian, or custodian in writing that a petition to terminate the parent-child relationship must be filed with respect to the child after June 30, 1999, if the child has been removed from the child's parent and has been under the supervision of a local office for at least fifteen (15) months of the most recent twenty-two (22) months. However, if a child's parent, guardian, or custodian fails to appear at the first periodic case review occurring after June 30, 1998, the local office shall make reasonable efforts to send notice of the advisement to the last known address of the parent, guardian, or custodian.
