Deciding to end a marriage is one of the hardest decisions a person can make. Knowing what the legal process looks like in Illinois can help you move through it with more clarity and less uncertainty.
Step 1: Meeting Illinois residency requirements
Before filing, at least one spouse must have lived in Illinois for at least 90 days. You file in the circuit court of the county where either spouse currently resides.
Illinois is a pure no-fault divorce state. The only ground for divorce is irreconcilable differences, and you do not need to prove wrongdoing by either spouse. If you have lived separately for at least six months, Illinois courts presume the marriage has irretrievably broken down. Both spouses can waive this period by agreement.
Step 2: Filing the petition for dissolution of marriage
The process begins when one spouse files a Petition for Dissolution of Marriage with the circuit court. Filing fees typically range from $300 to $450 depending on the county. Once filed and served, the responding spouse has 30 days to answer; however, in uncontested cases where an appearance and agreement are filed, you can have a judge enter a final judgment as soon as the court schedule allows.
Step 3: Formally notifying your spouse
The petition must be formally delivered to the other spouse after filing. Once served, the respondent has 30 days to file a response. Failing to respond can result in a default judgment.
Step 4: Completing financial disclosure
Both parties must complete a sworn financial affidavit disclosing all income, expenses, assets and debts. This is mandatory. Filing an inaccurate affidavit can result in court sanctions or attorney fee awards. If children are involved, parents must also complete an approved parenting education program of up to four hours, available online in most counties.
Step 5: Negotiating a settlement or going to court
Most Illinois divorces settle without a trial. When both spouses agree on property division, spousal maintenance and parenting arrangements, they submit a Marital Settlement Agreement to the court. If they cannot agree, a judge decides.
Contested divorces take significantly longer and cost more. Many courts also require mediation before scheduling a trial on parenting disputes.
Step 6: Finalizing the divorce
When the court approves the final terms, the judge signs a Judgment of Dissolution of Marriage, marking the official legal end of the marriage. Both spouses receive certified copies needed to update beneficiary designations, transfer property and change insurance coverage.
Getting the right support
Every divorce case has its own complications, whether that involves dividing shared assets, working out a parenting plan or navigating an uncooperative spouse. Having an attorney who understands Illinois family law can help you anticipate issues before they become costly problems and protect your interests at every step.
