My husband's father died (in Cook County, IL) after a long illness without leaving a will. He didn't own a house and we don't know if he had any accounts/assets other than a bank account that he accessed to pay bills. He was VERY private and didn't discuss whether he had any other assets. If there were records of other assets, they have not been found. He was divorced and my husband is an only child.
How do we determine if there are assets necessitating probate? Is probate necessary even if there are no assets? No idea where to start!
