To file for divorce in Illinois, one spouse must meet the residency requirement of living in the state for at least 90 days. Divorce filings must demonstrate “irreconcilable differences” as the reason for separation. To initiate the process, file a Petition for Dissolution of Marriage with your local court. The timeline and process for a divorce can differ significantly based on whether it is contested or uncontested. For contested divorces, court hearings may be needed to determine issues like property division, custody, and support.
