Whether it be maintenance to or from your current or former spouse, or support for your child(ren), your income is relevant in divorce and parentage proceedings. The fact that you are the person obligated to pay or the person who receives money from another does not change the need for your income to be defined before an order for support is entered.
“But what is my income? I am on social security benefits, or I run a business, or my income is constantly in flux. Surely, you cannot expect me to truly define my income. I’m special,” you say. Thankfully for you, the good and wise people of the Illinois legislature have defined what income is, and also what it isn’t, and they’ve done so in a way that isn’t confusing or contradictory at all. Rather than use a single definition for all family law purposes, they instead have defined income in three separate-yet-related statutes: the Uniform Interstate Family Support Act (“UIFSA”); the Income Withholding for Support Act, and the Illinois Marriage and Dissolution of Marriage Act (“IMDMA”).
