During that 72 hour period, parent(s) shall not have the right to revoke or terminate the Voluntary Placement Agreement. nor shall they have the right to know the whereabouts of the child, unless the child specifically agrees and unless the Department determines that to so inform the parent(s) would not be contrary to the child's best interests. At the conclusion of the 72 hour period, the Department shall either return the child to his/her parent(s), or shall institute court proceedings to obtain custody of the child, or shall obtain a Voluntary Placement Agreement signed by the mature child's parent(s).
