Many states, including Illinois, Indiana, and Wisconsin, now allow the placement of a lien on the real property of child support obligors. If your order was issued in court, you should call the circuit clerk in the county where your order was issued.Judgment liens only become liens against interests in real estate. The plaintiff must sign the document and you must then file with the circuit court clerk. A judgment becomes a lien on real estate when evidence of the judgment is recorded in the county in which the real estate is located. But a lien does not result in the immediate collection of the past due child support. The State holds the lien on all legal and equitable interests of responsible relatives in the amount of past-due child support. If one of these things is true, you can fill out the necessary forms then file them with the court. All Illinois Courts must accept these forms. Scroll down below the chart for important information on how to fill out these forms.
