Child Support

Child support in Illinois is not a percentage of one paycheck. Both parents’ net incomes go into it, and so does the number of overnights.

A Will County Child Support Attorney Who Fights for Fair, Enforceable Orders

Child support is the court ordered payment that covers a child’s needs after parents separate, and Illinois sets it with a statewide formula rather than a judge’s impression of what seems fair. Whether you are asking for support or answering a request for it, the numbers drive the result, and a misstated income or an overlooked expense changes what you pay or receive for years. Support is also not only arithmetic. It decides whether your child’s routine survives the separation intact, and whether both parents walk away feeling the split was honest. Jeff McCarthy represents Will County parents personally in support cases, from the first calculation through the enforcement or modification that comes later.

How Illinois Calculates Child Support

Illinois uses the income shares model under 750 ILCS 5/505. Both parents’ net incomes are combined, a basic support obligation is read off the Illinois Healthcare and Family Services child support schedules, and that obligation is divided between you in proportion to your share of the combined income. Parenting time changes the math in shared care cases, where the number of overnights each parent has is counted directly into the calculation. Childcare, health insurance premiums, school costs, and other extraordinary expenses are handled as add ons rather than being buried in the base figure. Jeff runs this framework before you file, so you know the likely order in advance instead of finding out at a hearing.

How a Support Case Is Filed, Decided, and Enforced

The case opens with a petition, either yours or the other parent’s. We prepare and file the paperwork in the right court, or draft the response if you have been served. Getting the filing right matters more than it looks, because the court’s authority to award support, and the date support starts running from, both trace back to this document.

Both parents then file a financial affidavit. That means pay stubs, tax returns, and documentation of childcare, health insurance, and education costs on each side. This is the step people are tempted to rush or shade, and it is the step that decides the number. An incomplete affidavit from the other parent is challengeable, and challenging it is often worth more than arguing about the formula.

With both affidavits in, the guideline figure is calculated. Most cases settle here into a stipulated agreement that the court approves. Where the guideline produces an unjust result, Illinois allows the court to deviate from it, and we make that argument with evidence when your circumstances genuinely justify one rather than because the number is inconvenient.

If no agreement is reached, we argue your position at a support hearing and the judge enters the order. After that the order is enforceable. When a parent falls behind, the remedies include wage garnishment and other collection tools, and we pursue them. When incomes or parenting time change substantially, the order can be modified, which is a separate filing and not something that happens automatically.

Support cases put pressure on co-parents that custody cases do not, because money is involved and trust is usually already low. You may be worried about affording the payment, angry at a co-parent who contributes nothing, confused about how the figure was reached, or anxious about what all of it means for your child. What you get here is a full analysis of your finances, a plain explanation of your rights, responsibilities, and options, protection from demands that the statute does not support, and advocacy aimed at your child’s stability rather than at winning an argument.

Speak With Jeff McCarthy About Your Child Support Case

Support outcomes turn on local practice as much as on the statute, and Jeff McCarthy knows the support commissioners, the judges, and what the Will County court expects to see in a financial affidavit. He handles the connected matters himself as well, custody, parenting time, enforcement, and modification, so the pieces stay consistent instead of being argued by different people in different rooms. He negotiates where negotiation gets a better number and litigates where it does not, and he explains the arithmetic until you can check it yourself.

FAQ

Illinois child support questions, answered

Plain answers to what people ask about child support in Will County.

Illinois uses the income shares model under 750 ILCS 5/505. Each parent's net monthly income is calculated using the state's conversion table, the two incomes are combined and looked up on the Illinois Schedule of Basic Child Support Obligations, and that basic obligation is split between the parents based on each one's share of the combined income. Parenting time also factors in, since once each parent has the child for 146 or more overnights a year the calculation adjusts to reflect that both households cover day to day costs. Call Jeff at (815) 838-5297 to see what the guidelines suggest for your situation.

Yes. Child support can be reviewed and changed when there is a substantial change in circumstances, such as a shift in either parent's income or in the child's needs. We can help you request a modification or respond to one.

It can. Under Illinois law, a court can order parents to contribute to the college and educational expenses of a non-minor child, including tuition, housing, and related costs. This is decided separately from regular child support and depends on the parents' resources and the child's needs.

Not usually. Support modifications only take effect from the filing date of the request, not before.

Yes, but only if both parents sign a formal agreement (stipulation) that’s filed with the court and legally enforceable.

Technically yes, but courts rarely allow it unless it clearly serves the child’s best interest and no public assistance is involved.
