Illinois Child Support Updates for Frankfort Parents
TL;DR: Frankfort parents follow the same Illinois child support statutes as the rest of the state, primarily the Illinois Marriage and Dissolution of Marriage Act. Support is generally calculated under Illinois’s “income shares” framework, and parenting time can matter in certain cases. If you are considering a change, gather clear income and expense records and talk with an attorney before filing.
Illinois child support is statewide
Child support in Frankfort (and throughout Will County) is governed by statewide Illinois law, primarily the Illinois Marriage and Dissolution of Marriage Act (IMDMA), found at https://www.ilga.gov/legislation/ilcs/ilcs3.asp?ChapterID=59&ActID=2086. Local court practices can affect scheduling and procedure, but the rules for setting and changing support come from state statutes.
How Illinois generally calculates child support (income shares)
Illinois generally uses an “income shares” approach to calculate child support. In broad terms, the court considers both parents’ financial information and applies the statutory framework in https://www.ilga.gov/legislation/ilcs/fulltext.asp?DocName=075000050K505 to arrive at a support amount intended to reflect the support a child would have received if the parents lived together.
Orders may also address certain child-related costs, such as health insurance and childcare, depending on the facts presented and what the statute authorizes.
Shared parenting time can affect the support calculation
Parenting time can affect how support is calculated in some situations. Illinois law includes provisions that allow parenting time to be considered in the support calculation where applicable. See https://www.ilga.gov/legislation/ilcs/fulltext.asp?DocName=075000050K505.
Because parenting schedules can be detailed (school-year vs. summer, holidays, transportation, and mid-week time), clarity matters. If you are asking the court to rely on a particular schedule, it helps to present a precise calendar and supporting records (for example, a consistent overnight log).
What counts as income (and why documentation matters)
Support calculations depend heavily on accurate financial disclosures. Documentation can include pay stubs, tax returns, and proof of other compensation. Illinois’s child support statute defines “net income” and outlines required inputs for the guideline calculation. See https://www.ilga.gov/legislation/ilcs/fulltext.asp?DocName=075000050K505.
If income varies (overtime, commissions, bonuses, seasonal work, or self-employment), organized records can reduce disputes and help the court evaluate income more reliably.
When parents seek updates to support: common reasons for a change
Many parents seek a change to child support after a significant shift in real-world circumstances. Examples may include:
- Job loss, new employment, or a substantial change in income
- A material change in parenting time
- New or changed childcare arrangements
- Changes to health insurance availability or premium cost
- Changes in a child’s needs
Whether an existing order can be changed (and from what date) depends on the statutory requirements and the specific facts. Illinois’s modification provisions are addressed in https://www.ilga.gov/legislation/ilcs/fulltext.asp?DocName=075000050K510.
Modification vs. enforcement: different tools, different goals
Modification is a request to change support going forward under the standards in Illinois law. Enforcement focuses on collecting support already due under an existing order.
In many cases, the Illinois Department of Healthcare and Family Services (HFS) provides child support services, including collection and disbursement functions. See https://hfs.illinois.gov/childsupport.html.
Tip: document parenting time and payments as you go
Small recordkeeping habits can prevent big disputes. If parenting time is contested or changing, keep a consistent overnight log and save messages that confirm schedule changes. If you pay for shared child expenses, keep receipts and proof of payment in one place.
Checklist: what to gather before a support review, negotiation, or court date
- Recent pay stubs and proof of any additional income
- Recent federal and state tax returns and W-2/1099s
- Proof of the child(ren)’s health insurance cost
- Childcare contracts, invoices, and proof of payment
- A proposed parenting schedule (or a log of actual overnights)
- Documents showing major changes (employment separation notices, benefit letters, medical documentation, etc.)
- If self-employed: bank statements, profit-and-loss reports, and business expense documentation
Will County and Frankfort logistics: where local process can matter
Even though the statutes are statewide, local procedure can still affect how your case moves (deadlines, financial disclosure practices, and scheduling). A lawyer familiar with Will County practice can help you comply with local expectations while grounding your case in the statewide requirements of the IMDMA.
FAQ

No. The rules for setting and modifying child support come from Illinois statutes, including the IMDMA (750 ILCS 5), though local practice can affect procedure and scheduling.
Can parenting time change the child support number?
It can in some cases. Illinois law allows parenting time to be considered in the guideline calculation where applicable under 750 ILCS 5/505.
Can I change support if income or expenses change?
Possibly. Modifications are governed by statutory standards and case-specific facts. See 750 ILCS 5/510 for modification provisions.
