Inherent authority to appoint GAL for minor litigant

Illinois courts have also said that “[c]ourts have inherent power to appoint a guardian ad litem for a minor involved in litigation; in fact, the trial court has a duty to ensure adequate representation of the minor's interest.”  In re Marriage of Vucic, 576 N.E.2d 406, 411 (Ill. App. Ct. 1991); see also In re Estate of Green, 835 N.E.2d 403, 407 (Ill. App. Ct. 2005) (“minor guardianships are derived from the common law and, therefore, a trial court inherently is empowered to appoint a guardian independent of any authority given to the courts under the Act.”).  However, no authority was found to indicate that the guardian ad litem must be an attorney.
