The Illinois Petition for Disabled (Adult) is a legal document used to request that the court appoint a guardian for an adult who is unable to care for themselves due to a physical or mental disability. The petition must be filed in the court of the county where the disabled adult resides. There are two types of Illinois Petition for Disabled (Adult): 1) Voluntary Petition for Guardianship of Disabled Person, and 2) Involuntary Petition for Guardianship of Disabled Person. The voluntary petition is filed by the adult or a relative or friend who is seeking guardianship for the disabled adult. The involuntary petition is filed by a state agency or a relative or friend of the disabled adult who is concerned about the disabled adult's health and safety. The petition must include information about the disabled adult's financial, medical, and psychological condition, as well as the name of the proposed guardian. The court will then consider the petition and make a decision regarding whether guardianship is appropriate.
