Illinois Single Mom Guide: Custody Laws, Child Support, Benefits, and Legal Help

Illinois significantly reformed its family law in 2016, replacing traditional custody terminology with new language and restructuring how courts approach parenting arrangements. If you’ve seen older information about Illinois custody, it may no longer reflect current law.

Illinois Child Support

Illinois moved to an Income Shares model in 2017, replacing its previous flat-percentage approach. Both parents’ net incomes are now combined to determine a basic support obligation, which is then divided proportionally.

Key Illinois-specific facts:
– Illinois uses net income for its child support calculation — after taxes and certain mandatory deductions — similar to Pennsylvania and distinct from states using gross income
– Parenting time adjustment: Illinois applies a reduction when the paying parent has 146 or more overnights per year (40% or more of overnight time), using a formula that reflects the shared costs of raising the child in two households
– Healthcare and work-related childcare costs are allocated proportionally between parents in addition to the basic obligation
– Child support in Illinois is enforced through the Illinois Division of Child Support Services (DCSS), which provides free services including establishment, enforcement, and payment processing
– Illinois uses the State Disbursement Unit for payment processing — support is typically paid through this central system rather than directly between parents

Illinois Custody Law

Illinois’s 2016 Marriage and Dissolution of Marriage Act eliminated the terms “custody” and “visitation,” replacing them with allocation of parental responsibilities and parenting time — a significant terminology shift that reflects a changed approach to how courts think about co-parenting.

Key Illinois-specific facts:
– Allocation of parental responsibilities covers decision-making authority over significant matters: education, healthcare, religion, and extracurricular activities. These can be allocated jointly or to one parent, and can even be split by category — one parent making educational decisions, the other healthcare decisions
– Parenting time replaces visitation — it refers to the time each parent physically spends with the child, regardless of who has decision-making authority
– Illinois courts apply a best interest standard considering 17 statutory factors, including each parent’s willingness to facilitate a relationship with the other parent, the child’s adjustment to home, school, and community, and any history of domestic violence
– Child’s preference is one of the 17 factors, considered based on the child’s maturity — there is no specific age threshold in Illinois
– Relocation in Illinois: a parent with the majority of parenting time who wants to relocate more than 25 miles from their current residence (or across state lines) must provide 60 days’ written notice and, if the other parent objects, obtain court approval. The 25-mile threshold is notably lower than many states
– Domestic violence is a significant factor under Illinois law — courts presume that allocating parental responsibilities to an abuser is not in the child’s best interest

Illinois-Specific Points Worth Knowing

• The 2016 terminology shift matters practically — if you’re searching for Illinois custody information, older articles using “custody” and “visitation” may not reflect current law; look for content referencing “allocation of parental responsibilities” and “parenting time”
• Illinois’s 25-mile relocation threshold is notably lower than most states — a parent with primary parenting time moving just across a county line may still need to provide notice and get approval
• Split allocation of parental responsibilities by category is a real option in Illinois that some other states don’t allow — if you and your co-parent have different areas of strength, this can be worth discussing with an attorney
• All Kids’ coverage of all children regardless of immigration status makes Illinois’s CHIP program more inclusive than most states — worth knowing if immigration status has been a barrier to seeking healthcare coverage for your children
• Illinois Legal Aid Online is genuinely excellent — if you’re navigating any family law matter without an attorney in Illinois, this is the first resource to consult
