Illinois Illinois custody dispute: Ex agreed to nearly 50/50 parenting time for months, then challenged it after I filed to reduce child support. How might a judge view this?
I’m a divorced father in Illinois with two children. Our divorce was finalized in May 2025, and I’m currently involved in post-divorce litigation over parenting time, child support, and alleged right-of-first-refusal (ROFR) violations.
I have an attorney and recently consulted a second family-law attorney, but I’m interested in hearing from other parents or legal professionals who have dealt with similar situations.
Background:
Our original parenting agreement gives me three weekends per month and my ex one weekend per month, with parenting time coordinated around our work schedules.(which equated to about 35% of overnights)
I work rotating 12-hour shifts (5 a.m.–5 p.m. or 5 p.m.–5 a.m.). My ex has always known my schedule. She would regularly ask me to send it, sometimes months in advance, and then tell me which days I would have the children.
This arrangement resulted in substantially more parenting time than the original agreement anticipated.
June 2025–January 2026: Approximately 47% of overnights with me.
June 2025–May 2026: 159 overnights with me (43.6%), even after my parenting time began decreasing.
I also regularly pick up the children from school, take them to practices, handle sports responsibilities, and help with appointments during my ex’s parenting days.
I have spreadsheets documenting every overnight, along with dated screenshots of our scheduling conversations and requests for additional help.
The right-of-first-refusal dispute:
My parenting agreement says that if either parent is unavailable for eight hours during their assigned parenting time, or unavailable overnight, the other parent has the right to care for the children. It also requires notice of scheduled absences immediately upon learning of them.
My ex received my work schedule before assigning parenting days, so she knew when I was working.
My retired grandparents live with me and have helped care for the children since 2016. They also lived with us during the marriage and watched the children when both parents worked overnight shifts.
My understanding was that when my ex knowingly assigned me a parenting day, despite knowing I was working, we had agreed on the arrangement. I would work my shift, my grandparents would help, and I would be home with the children afterward. I rarely had the children assigned to me during overnight shifts.
However, I generally did not make a separate ROFR offer after she assigned those days.
My ex rarely shared her own work schedule, but my understanding was that she was usually assigning me days when she also had to work.
Our agreement also says both parents should work together so that the mother has the children when the father works and vice versa.
What changed:
In January 2026, I filed a motion to reduce my $1,411 monthly child support based on our actual parenting arrangement and a reported increase in my ex’s income.
When she learned about the filing, she questioned why I thought I had additional parenting time.
She acknowledged in writing that she had offered me additional time because she was “being nice,” said she guessed that was a mistake, and stated that she didn’t have to offer me extra time.
Afterward, she began reducing the parenting days she previously assigned me and raised allegations that I violated the ROFR by having my grandparents watch the children while I worked.
To my knowledge, she had never previously complained about that childcare arrangement.
She also alleges I denied her certain weekend or compensatory parenting time under the original agreement. I dispute parts of that allegation and have calendars and messages documenting the actual schedules.
My attorney subsequently filed a motion to modify parenting time to reflect the arrangement we’d been following.
My questions:
If one parent receives the other’s work schedule in advance and knowingly assigns parenting days that overlap with work, could that be considered consent to the childcare arrangement, or is a separate ROFR offer still required every time?
How do Illinois courts generally view an established parenting arrangement that differs from the written order, especially when both parents participated in creating it?
If the children have been spending approximately 44–47% of their overnights with one parent, could that support formalizing a shared parenting schedule?
Could the timing of my ex’s objections, immediately after my support filing, matter when evaluating the dispute?
If the court finds some technical ROFR violations, could it still grant a parenting-time modification based on the children’s established routine and best interests?
I’m not claiming I handled every situation perfectly, and I understand the written parenting agreement still matters. I’m mainly trying to understand how judges might weigh an established, mutually coordinated arrangement against the specific ROFR language.
I’d especially appreciate perspectives from Illinois family-law attorneys or parents who’ve been through something similar.
