Not sure about the Illinois laws, but I know several celebs have been successfully sued for pallimony (sp?). It's like alimony but you don't have to be married to get it. Basically if the other party (cause it's not just limited to women!) handled 'spousal duties' for a period of time and was not able to earn a living then he/she may be eligible for some support. I don't think you have to have children to sue for pallimony. At least that is the way I remember it from Entertainment Tonight type shows!
