Must a guardian ad litem be an attorney?

In the state I practice (IL) generally the Guardian ad Litems (GALs) are attorneys HOWEVER, the probate statue allows for non-attorneys to be appointed.  The statue says specifically:  If the GAL is not a licensed attorney, he or she shall be qualified, by training or experience, to work with or advocate for the developmentally disabled, mentally ill, physically disabled, the elderly, or persons disabled because of mental deterioration, depending on the type of disability that is alleged in the petition. Also note that the court may allow the GAL reasonable compensation.
