When parents separate, getting child support right is essential for stability. Work directly with Jordan Greenberg at the Law Office of Jordan Greenberg — a solo child support lawyer serving Chicago and suburbs — to calculate fair support, modify outdated orders, and enforce obligations with minimal conflict.
How Illinois Calculates Child Support
Illinois uses an income shares model that looks at both parents’ income and parenting time to set support. The court can also account for health insurance, child care, extraordinary medical costs, and educational expenses. The rules live in the Illinois Marriage and Dissolution of Marriage Act: 750 ILCS 5 (see § 505 for core child support guidelines). A precise calculation requires current pay stubs or profit and loss statements, tax returns, health premium documents, and the actual parenting schedule — not estimates.
- Income shares worksheet built from verifiable documents
- Adjustments for health insurance, out-of-pocket medical, and child care
- Shared parenting time credits when overnights meet statutory thresholds
- Add ons or deviations when the guideline number is unfair on the specific facts
If you searched for child support attorney or legal family advice, the starting point is numbers plus a realistic look at weekly logistics. That combination drives durable orders and fewer post judgment disputes.

Modifying Support When Life Changes
Support is not frozen forever. A substantial change in circumstances — job loss, income growth, health costs, schedule shifts — may justify a new amount. Illinois allows modification when the guideline result would change significantly or a material circumstance has shifted. See 750 ILCS 5 (including § 510 on modification). As a spousal support modification attorney and child support lawyer, Jordan aligns updated proof with a targeted petition so adjustments are grounded in evidence, not assumptions.
- Document changes: new pay records, employer letters, medical statements, child care receipts
- Rebuild the worksheet and compare old and new results
- Propose interim steps — temporary payments or cost sharing — while the case is pending
- Convert agreements into a clear order that payroll can implement without delay
The most persuasive modification request pairs clean numbers with a short, factual story. No drama — just proof and a guideline that points to the right outcome.
Enforcement and Defense
When payments stop, enforcement tools include income withholding, judgment for arrears, interest where the statute allows, and contempt proceedings for willful nonpayment. When an order is wrong or circumstances changed long ago, defense may focus on correcting the amount and setting a realistic catch up plan rather than escalating penalties.
- Accounting that distinguishes principal, interest, and credits for direct payments
- Income withholding orders tuned to payroll cycles to prevent shortfalls
- Negotiated consent orders that reduce court time and future disputes
- Protection against improper demands when records or amounts are inaccurate
For interstate issues or employer changes, we coordinate the transfer and re issuance of withholding so support continues without gaps.
Spousal Support and Related Family Orders
Many families address spousal support at the same time as child support. Illinois uses formulas and factors for maintenance based on income and marriage length, with caps and exceptions. Alimony attorneys often call this “maintenance” in Illinois. We explain the range, how it interacts with child support, and when a deviation makes sense. If you need spousal support attorneys for a modification or termination request, the playbook is similar — updated proof plus a focused petition.
- Side by side modeling of maintenance and child support to avoid double counting
- Tax treatment review for current law rather than outdated assumptions
- Integrated drafting so parenting plans, support, and insurance obligations do not conflict
