no it is not the law. there may be a local court rule requiring disclosure from both of you by a certain time. if not, then she or he who asks, gets. she asked, you did not.
since you do not know the procedural rules, why not hire a lawyer who does?
I think you're in Cook County. Cook County has a rule that deals with this. It's too long to go into in this forum. You need to know the rules.

There is no requirement that you must "show me yours before requiring me to show you mine." Financial disclosure, with only sa few exceptions, must e requested or it is not offered. You need a lawyer.
Check your local court rules, but neither the Illinois Marriage and Dissolution of Marriage Act nor the Supreme Court Rules require a person requesting discovery, such as a financial disclosure, to first disclose his or her finances before requesting the same from you.
