In T.M.F. v. Children's Service Society, 112 Wis. 2d 180, 332 N.W.2d 293 (1983), the supreme court was reviewing a parent's application for voluntary consent to terminate parental rights, see id. at 182. The Court also observed that a fixed rule could not be set out as to what information must be provided a parent in each termination case or what questions must be asked or what responses must be elicited. However, the court cautioned that the juvenile court must be "vigilant in protecting the interests of all parties." Id. at 196.
