I totally agree with cyjeff and mmmagique. He needs his own attorney.

In addition, I believe in Illinois there is no waiting period if there are grounds for divorce filed. If they go no-fault, then there is a 6 month waiting period if they both agree.

Six months is not really that long. It will probably take that long to hammer out the details. However, if she wants the divorce right away, then SHE should agree to letting him file on the grounds of mental cruelty!
