Does my divorce petition have to be filed in a particular county?
Divorce proceedings should take place in the proper venue under Illinois law. This is the county in which either you or your spouse resides. If you are a resident, it is possible to file for divorce in a county where neither you nor your spouse currently resides. However, if you do so, you will need to file a motion along with your petition for divorce explaining why you chose to file in that county. For example, if you live in one county but work in another, it might be reasonable to file for divorce in the county where you work.
