Child Support Modification Lawyer in Chicago, IL

Representation for Child Support Changes After a Substantial Life Change

Everything changes with time, and child support orders that are first issued by the court when a couple divorces may be subject to change with life circumstances. Although it is not always easy to obtain an Illinois child support modification, there are circumstances which occur in a child or parent’s life that may require a change in child support. 

When couples divorce, the court issues orders regarding a variety of financial matters, including any applicable child support.

Time passes and things change, including circumstances for each party regarding their financial or living situation. Even with new circumstances, changing an existing court order is more involved than simply showing that your situation has changed.

If the time has come for you to pursue a modification to your child support or oppose a Petition for Modification of Child Support filed by your ex, call on Anderson Boback & Marshall. 

Our attorneys are child support adjustment lawyers in Chicago with the expertise necessary to help you obtain a modification of your child support order. If you live outside of Illinois but have a case pending in the family courts in Chicago and surrounding counties.

Requirements for Modification of Child Support in Illinois

We Conduct Careful Analysis of the Law and Your Circumstances

Modifying orders issued from a divorce proceeding or child custody case depend upon whether the order affects the financial support of the child or the placement and custody of the child. If requesting to modify the financial child support, a party is required to show evidence of a substantial change in circumstances.

Evidence the court looks at when determined if a substantial change of circumstances has occurred may include, but is not limited to the following:

  • An increase in income or bonuses paid
  • A second job
  • Involuntary pay cuts
  • Losing a job involuntarily through a layoff
  • Additional medical expenses for a prolonged illness
  • Any other events that affect the earning power or income of either party

If you have experienced any of these life-changing circumstances since your original child support order was issued, contact Anderson Boback & Marshall for help in obtaining an Illinois child support modification.

Seeking Modifications of Child Allocation Plans

If you wish to modify a child allocation plan, custody agreement or parenting time, you must provide evidence to the court to support your request for modification. The requirements for issuing a modification a child allocation plan include:

  • A two-year waiting period since the date of the last custody order with significant changes in circumstances warranting a modification along with Affidavits proving a serious threat to the mental, emotional or physical health of the child which cannot wait the two years
  • A change in circumstances that is in the best interest of the child

Natalie E.
I had, what I believed at the time, a simple divorce case that I initially filed on my own. My now ex husband made the case impossibly drawn out, utterly nonsensical, and frustrating. I hired Laura Darby from Anderson Boback & Marshall to represent me because I was exhausted of going in circles trying to get answers from my ex and his attorney. Laura was supportive, experienced, and very responsive with respect to resolving the matter. She jumped into the case and then consistently stayed on top of it to keep it moving along in the court system. I appreciated her insight and the fact that she listened to my concerns and offered reasonable suggestions on how best to proceed. She also kept the cost of services fair and reasonable for someone without a ton of disposable income. Thanks to Laura's efforts the case has finally wrapped up and I'm grateful to be done with it and free. Overall, a fantastic attorney that knows the legal system and does everything in her power to represent your interests.
Response from the owner:It was an absolute joy bringing your matter to a resolution for you! Thank you so much for your kindness and allowing us to advocate for you!
Parth P.
From the moment I had my initial consultation with one of the attorneys on staff, I could tell that I was in good hands. They took the time to understand not only the logistical details of situation, but also the emotional turmoil of going through a divorce process. Their communication throughout was excellent, they seamlessly performed all the necessary work via email and phone calls, and when a tricky situation came up in the 11th hour they navigated it effectively and presented me with options on how we could proceed. Thank you so much!
Response from the owner:Thank you, Parth for your kind words. Our team is honored to serve you and we are thrilled that you are happy with our representation.
Chris D.
I highly recommend the services of Anderson Boback & Marshall. I retained the firm in May 2025 and, thanks to the exceptional work of my attorney, M. Barrett, we reached a desirable agreement with the opposing party in just a few months. M. Barrett provided incredible strategic development and great advice throughout the entire process. I am especially grateful for the knowledge and confidence they provided during a challenging time. Communication was always prompt and professional. Furthermore, I was happy with the firm's transparent billing. There were no hidden fees or charges.If you are looking for effective representation and a team that truly delivers, I highly recommend M. Barrett and the team at Anderson Boback & Marshall.
Response from the owner:Thank you, Chris! We’re so glad Monika and our team could guide you through a challenging time with clarity and results. We truly appreciate your trust and recommendation.
Elizabeth Bailey
I really appreciated Laura’s help on my case. She was professional, empathetic, knowledgeable, and very quick to respond. She made an unfortunate situation much more tolerable with her ability to move my case along quickly and easily. Highly recommend.
Audrey Tabon
I’ve been working with Anderson and Boback since 2019 due to the unfortunate complexities of my case. It’s been exhausting and expensive but having this group of powerful attorneys has been pivotal in the success of my case.
Timothy Host
Attorney Jessica's exceptional assistance and success in securing a proper visitation agreement and reuniting me with my daughter surpassed my expectations. Her prompt correspondence and attention to detail were remarkable, ensuring efficient communication and leaving no aspect of my case overlooked.
Paul Cavill
Laura was my assigned Attorney and she was very professional and did an excellent job. Great advice and did everything as quickly and easily as possible. I couldn't of gone through the unfortunate process I had to and got the outcome I did without her. Highly recommend.
Dan Strickland
Words cannot express the gratitude I have for Jessica Marshall and her team. As a father who was no longer present in the USA, I was facing a monumental task to get access to my daughter in the face of extreme hostility. She made the impossible happen, and I’ll forever be in her debt.
Kelly Olsen
We never go into a marriage thinking I have a great divorce attorney if this doesn’t work out. However, Laura Darby is the attorney you want in your back pocket if you do have to go through a divorce! Laura is extremely knowledgeable, caring, and will advocate for her clients. She will provide realistic, clear, and yet supportive guidance to her clients.
Karen Mae
If you’re looking for a smart, reliable divorce attorney, look no further. I was able to collect many years of back support with the assistance of this office. Jessica Marshall really knows what she is doing and I felt that my outcome was fair. You really do get what you pay for.
Rob Backeberg
My experience with Anderson & Boback was nothing short of professional, efficient and caring. My lawyer, Jessica Marshall, provided a strong sense of guidance, reassurance and a human touch during a very difficult and complicated legal process. Highly recommend Jessica and her team.
Raza K.
Jessica is a dedicated, intelligent and a skillful attorney. Her arguments are skillfully articulated. She helped me in getting my divorce finalized in 2018. She then helped in getting the past due child support from my X-spouse and then recently in getting the maintenance alimony payments settled. I would highly recommend their services.
Joanna Kieplin
Jessica C. Marshall , partner at Anderson & Bobak is one of the best attorneys I had a pleasure to work with! I wish I had found her sooner in my divorce process. I had a post decree military pension issue and it was resolved quickly, efficiently and effectively. I didn’t even have to go to court or interact with my ex- spouse. The billing was also very straightforward and honest. Highly recommended attorney!
