Defined under the state of Illinois, a dissolution of marriage can be thought of as the divorcing of a married couple. As long as the marriage was considered valid in one of the United States, parties can get divorced in Illinois if either individual lived in the state for 90 days prior to filing or 90 days before a judgment would be entered. While each county has its own local court rules that might guide certain issues or require that some procedures take place in a certain order, your dissolution of marriage is defined by the state that you reside in.
