Child Support in Illinois

Although Child Support Law in Illinois is a Straightforward Issue in Divorce, it Remains a Point of Contention – Especially with the New Laws

While child support is a basic right granted to a child of any relationship, it remains one of the most contested issues in any Illinois divorce.

The concerns of both parties include:

  • If you’re the receiving parent with the majority of the parenting time, you will always want (or expect) more child support.
  • If you’re the paying parent, you simply want to pay what is necessary and in the best interest of your family.

At Lawrence R. Surinak Ltd., we’ve been carefully handling these matters and disputes for over 35 years. Regardless of whether we’re representing the receiving or paying parent, we thoroughly calculate child support payments to come to an agreement that is fair for both parties. As such, you can look to our firm as your trusted partner, no matter your position in a divorce proceeding.

So, What is Child Support and How is it Calculated in Illinois? 

Child support is as it sounds: It is regular payments provided from one spouse to the spouse granted the majority of the parenting time (i.e. custody).

The guidelines dictating the amount of child support in Illinois are straightforward. In fact, child support is calculated in accordance with Section 505 of the Illinois Marriage and Dissolution of Marriage Act, which allocates support based on the number of children from the marriage.

Here is the amount of support you can expect to pay or receive as part of your divorce:

  • One Child – 20% of net income
  • Two Children – 28% of net income
  • Three Children – 32% of net income
  • Four Children – 40% of net income
  • Five Children – 45% of net income
  • Six or More Children – 50% of net income

If the Laws Say Child Support in is Calculated by the Number of Children, What is There to Dispute? 

Most often, the definition of “net income” is hotly disputed during child support calculations. According to Illinois state law, net income includes all income earned minus:

  • Federal and state income taxes
  • FICA – This includes costs like social security and Medicare
  • Retirement contributions (only those which are mandatory)
  • Union dues
  • Health insurance premiums
  • Life insurance premiums, but only if ordered by the court to guarantee payment
  • Existing child or spousal support payments
  • Costs necessary for the repayment of debt

There are several other issues that can emerge as well, including:

  • How parental responsibilities are allocated
  • Disputes over current income and earning potential
  • Additional expenses that diminish income, such as tuition for minor children, medical expenses, extracurricular activities, etc.

Our firm is experienced in these matters and others and will protect your interests in any divorce proceeding. We consider it our responsibility to ensure payments are fair and just for both parties and will defend your interests in negotiations or at trial, whichever your case necessitates.

Common Child Support Law Questions:
How Long Does Child Support Last in Illinois?

Whether you are to pay child support or you are to receive payments, it’s a central issue in any case. After all, children are (and should be) the first concern in any divorce, especially because they must be provided for physically, financially, and otherwise.

One of the most common questions is how long it must be paid. As you may suspect, there are laws in Illinois that govern this and as such, you can have a clear answer of what to expect from child support payments.

In this article, we discuss how much child support must be paid as well as for how long so you can better understand the financial implications of your divorce in Naperville, Wheaton, or the surrounding areas.

How Can I Use a Calculator to Determine How Much Child Support Must I Pay By Law?

In almost every divorce, the Court uses the same guidelines to calculate payments according the Illinois Marriage and Dissolution of Marriage Act and family law. This also eliminates your need for something complicated like a child support calculator. These guidelines are as follows:

  • 1 Child – 20 percent of supporting party’s (i.e. parent’s) net income.
  • 2 Children – 28 percent of supporting party’s (i.e. parent’s) net income.
  • 3 Children – 32 percent of supporting party’s (i.e. parent’s) net income.
  • 4 Children – 40 percent of supporting party’s (i.e. parent’s) net income.
  • 5 Children – 45 percent of supporting party’s (i.e. parent’s) net income.
  • 6 or More Children – 50 percent of supporting party’s (i.e. parent’s) net income.

However, this isn’t the case in all divorce proceedings. For example, if the spouse who is paying support makes a significant amount of money and the calculations above would result in a disproportionate amount of money unnecessary to support the children, the Court will deviate from the calculations above to make an appropriate ruling. The most common reasons for deviations include:

  • The financial needs and resources available to the child(ren);
  • The financial needs and resources available to the parents;
  • The standard of living the child(ren) would have experienced if the divorce had not happened;
  • The physical, mental, and emotional needs of the child(ren); and
  • The educational needs of the child.

How Long Must I Pay/Will I Receive Child Support in Illinois? 

Like the legal guidelines above that dictate what most spouses pay for child support, the length of the child support obligation is fairly straightforward as well.

Most supporting parents are ordered to pay child support until each child reaches the age of 18 or graduates from high school. In certain cases, for example if the child has special needs or there are other special circumstances, this may differ.

While you can expect to pay or receive child support until each child graduates from high school, it’s important to remember that the amount may change over time. Let’s say that you lose your job and don’t make as much at your new job. Your child support obligation will decrease based on your new net income, though you will have to return to Court to receive this reduction.
