A divorce, also referred to as a marital dissolution, is the termination of a marriage by court order. In Illinois, there is a 90 day residency requirement, meaning that the husband or wife must have lived in Illinois for 3 months. If neither spouse has lived in Illinois for the required 90 days, then the Illinois court system cannot grant a divorce. The proper court for filing for divorce in Illinois is the circuit court for the county where either spouse lives. The Illinois divorce law section can be found at
