Legislators and bar associations consult with Mr. Feinstein to obtain his opinions concerning proposed legislation. Paul Feinstein is on the Circuit Court of Cook County Domestic Relations Division's list of court-approved mediators for both financially related issues and custody related issues. He is also court-approved to be appointed as child representative, guardian ad litem and attorney for children in contested custody, removal and visitation disputes. Paul Feinstein is also trained in Collaborative Divorce and is a Fellow of the Collaborative Law Institute of Illinois and a member of the International Academy of Collaborative Professionals.
