I work in Will County and there are people on my caseload who are wards of the state of IL. It is true that you, as involved family, will have an opinion but no rights. And the rep from the state guardian's office who is assigned to your Dad may listen to your opinion but not agree with it and he/she will be the one making the legal decisions. As family members, you can present to the judge your reasons why one of you should become guardian rather than having your Dad become a ward of the state. In my experience, the courts, etc. would prefer a family member to step forward as the state guardian's office is already short staffed, etc. like many other government offices. I would get a lawyer who can go over the particulars of your situation. If finances are a concern, call Will County Free Legal. They will do a consultation at no charge and have a sliding fee scale after that. You may be able to get enough assistance from them. Good Luck! I'm sure this is a hard situation for your family.
