In Illinois, a Guardian Ad Litem (GAL) is a court-appointed individual—usually an attorney—who investigates a family law case and submits a report with recommendations in the best interest of a minor child. The GAL’s report typically suggests a visitation schedule and which parent should have decision-making authority. This role ensures the court has an objective assessment focused on the child’s welfare. See 750 ILCS 5/506 for the governing statute.
