An Illinois Motion to Terminate Support is a legal motion used in Illinois family law to terminate a court's order of child support or spousal maintenance. This motion can also be used to modify a court's order of support that is already in effect. There are two types of Illinois motion to terminate support: voluntary and involuntary. A voluntary motion is one that is filed by the paying party, while an involuntary motion is filed by the receiving party. The motion must provide details of the reason for the termination, such as a change in financial circumstances, the death of the receiving party, or the emancipation of the child receiving support. The motion must also include evidence to support the motion. Upon filing the motion, the court will determine whether to grant the motion and terminate the support order.
