The Law Office of Zachary W. Williams is dedicated exclusively to the practice of family law throughout the Chicago area.

Zach Williams has over 20 years of experience inside the family court system that has earned him the respect of judges, many of whom appoint him to represent children. His insight and knowledge enable him to more effectively advocate for his clients, whether he’s negotiating a settlement, preparing for mediation or fighting at trial.


Our extensive combined experience in family law can help guide you in the following areas:

• Child Custody and Visitation
• Divorce (Contested/Uncontested)
• Child Support
• Parentage and/or Paternity
• Mediation
• Removal
• Civil Unions/Same-sex Marriage
• Hague Convention Actions
• Grandparents’ Rights and Visitation
• Juvenile Law
• Prenuptial/Postnuptial Agreements
• Child Representation
• Legal Separation
• Civil Orders of Protection
• Domestic Violence
• Marital Property Settlement
• Child Protection (Abuse and Neglect)
• Enforcement of Judgments or Court Orders


We are mindful of the emotional complexities of family law. We believe it is important to maintain civility and collaboration wherever possible. In an effort to maintain this approach, we are committed to involving alternative dispute resolution practices when possible, and encourage mediation before contested litigation. However, we understand that not every case is appropriate for mediation and work with our clients to determine the best course of action in a particular case. If litigation is necessary, we become forceful advocates, helping our clients achieve the results they deserve. Finally, we believe that each of our clients deserves individual attention as well as explanations they can actually understand.
