Filing for divorce in Illinois requires completing and submitting specific legal documents to your county circuit court. The primary document is the Petition for Dissolution of Marriage, governed by the Illinois Marriage and Dissolution of Marriage Act (750 ILCS 5). Filing fees range from $250 to $388 depending on your county, with Cook County charging $388 and DuPage County charging $348. Illinois requires only 90 days of residency before you can file, and the state operates as a purely no-fault jurisdiction since 2016, meaning you only need to cite irreconcilable differences as grounds.

What Divorce Papers Do You Need in Illinois?
Illinois divorce papers consist of court-approved standardized forms that must be filed with your county circuit court to initiate and complete a dissolution of marriage. The Illinois Supreme Court has approved statewide standardized forms that all Illinois courts must accept, making the process more uniform across the state's 102 counties. The primary document you need is the Petition for Dissolution of Marriage, which officially requests the court to end your marriage under 750 ILCS 5/401.
The required forms depend on whether you have minor children and whether your divorce is contested or uncontested. For divorces without children, you typically need 5-7 forms, while divorces involving children require 8-12 forms including parenting plans and allocation of parental responsibilities documents. Cook County reports that 68% of divorce filings involve the standard dissolution process, while 32% qualify for the simplified procedure.
Essential Divorce Forms for Illinois
The Petition for Dissolution of Marriage is the foundational document that initiates your divorce case under 750 ILCS 5/401. This form must include both parties' names and addresses, the date and place of marriage, grounds for divorce (irreconcilable differences), and information about minor children if applicable. You must file the original petition plus two copies with your circuit court clerk, and the filing fee ranges from $250 to $388 depending on your county.

Forms for Divorces with Children
When minor children are involved, Illinois requires additional parenting-related documents under 750 ILCS 5/602.10. These forms address parenting time, decision-making responsibilities, and child support obligations. The parenting education class costs $35-$75 per parent and must be completed before the court will enter a final judgment.
Required child-related forms include:
- Allocation of Parental Responsibilities: Designates decision-making authority for education, healthcare, religion, and extracurricular activities
- Parenting Plan: Details the parenting time schedule, including holidays, vacations, and transportation arrangements
- Child Support Worksheet: Calculates support using the Income Shares Model under 750 ILCS 5/505

Fee Waiver Eligibility
Illinois Supreme Court Rule 298 allows fee waivers for individuals who cannot afford court costs. You qualify if your household income falls at or below 125% of the federal poverty guidelines, which for 2026 means annual income below approximately $18,500 for a single person, $25,000 for a household of two, or $37,500 for a family of four. You must complete an Application for Waiver of Court Fees and submit it with your petition.
Approximately 23% of divorce filers in Illinois receive full or partial fee waivers according to Administrative Office data. The application requires documentation of income, assets, and monthly expenses. If approved, the waiver covers the filing fee, service fees, and most other court costs.
How to File for Divorce in Illinois: Step-by-Step Process
Filing divorce papers in Illinois follows a structured process that takes 45-60 days for uncontested cases and 6-18 months for contested divorces. The process begins with preparing your petition, continues through service of process, and concludes with a final hearing and judgment. Understanding each step helps avoid delays that can extend your timeline by weeks or months.
Step 1: Meet Residency Requirements
At least one spouse must have lived in Illinois for a minimum of 90 consecutive days immediately before filing under 750 ILCS 5/401(a). There is no county-specific residency requirement, but you must file in the county where either spouse resides. Active-duty military members stationed in Illinois satisfy the residency requirement even without legal residency. You can file your petition on day 91 of residency with no waiting period required.
Step 2: Complete Required Forms
Gather and complete all necessary divorce papers based on your specific situation. For a standard dissolution without children, you need the Petition for Dissolution of Marriage, Summons, Financial Affidavit, and proposed Judgment. Divorces with children require additional parenting forms. Double-check that all forms are current versions from official sources and that all required fields are completed accurately.
Step 3: File with the Circuit Court Clerk
Submit your completed petition to the circuit court clerk in your county of residence. Illinois requires e-filing through the statewide electronic filing system (eFileIL) in most counties, though some courts still accept paper filings. You will receive a case number and initial court date at filing. Keep copies of all filed documents for your records.
Step 4: Serve Your Spouse
After filing, you must formally notify your spouse of the divorce action through service of process under 750 ILCS 5/411. Service methods include personal service by a sheriff or private process server ($50-$100), service by certified mail with return receipt requested, or service by publication if your spouse cannot be located. Your spouse has 30 days from service to file a response.
Step 5: Complete Financial Disclosures
Both parties must exchange complete financial information including income documentation, tax returns from the past 3 years, account statements, and debt information under 750 ILCS 5/501. Failure to provide accurate disclosures can result in sanctions and may affect property division. Financial disclosure typically takes 30-60 days to complete.
Step 6: Negotiate Settlement or Proceed to Trial
If both parties agree on all terms, you can submit a Marital Settlement Agreement for court approval. If disputes exist regarding property, support, or children, the court will schedule mediation or a trial. Contested issues require evidence, testimony, and judicial determination, extending the process to 6-18 months.
Step 7: Attend Final Hearing
Once all issues are resolved, either party (or both in uncontested cases) must appear for a final prove-up hearing. The judge reviews the settlement agreement or enters judgment on contested matters. If approved, the court enters the Judgment of Dissolution of Marriage, officially ending the marriage. The Certificate of Dissolution is issued afterward for official records.
Joint Simplified Dissolution: The Fastest Option
Joint Simplified Dissolution under 750 ILCS 5/452 offers the quickest path to divorce in Illinois, with cases finalized in as few as 30 days. This streamlined procedure requires both spouses to agree on all terms and meet strict eligibility requirements. Approximately 15% of Illinois divorces use this expedited process, which costs less and requires minimal court involvement.
Eligibility Requirements
To qualify for Joint Simplified Dissolution, couples must meet all of the following criteria under 750 ILCS 5/452:
- Married less than 8 years
- No minor children born to or adopted by the couple, and wife is not currently pregnant
- Total marital property value is $50,000 or less (after deducting debts)
- Combined gross annual income is under $60,000, with neither spouse earning more than $30,000
- Neither party owns real estate
- Neither party has retirement benefits except IRAs with combined value under $10,000
- Both parties waive any right to spousal maintenance
- Both parties agree on division of all assets and debts
Required Forms for Joint Simplified Dissolution
The Joint Simplified Dissolution packet includes:
- Joint Petition for Simplified Dissolution of Marriage
- Affidavit in Support of Joint Petition
- Agreement as to Division of Property and Debts
- Judgment of Dissolution of Marriage
- Application for Waiver of Court Fees (if applicable)
Both spouses must sign all documents before a notary public. The filing fee for Joint Simplified Dissolution is typically $285-$350 depending on county, lower than standard dissolution fees because both parties file together.
Court Appearance and Finalization
Both spouses must appear together before the judge on the scheduled hearing date. Joint Simplified Dissolution hearings are typically heard the same day as filing in many counties. The judge reviews the petition and agreement to ensure eligibility requirements are met and the agreement is not unconscionable (grossly unfair to either party). If approved, the judgment is entered immediately, and the divorce is final.
Property Division in Illinois Divorce
Illinois divides marital property using equitable distribution under 750 ILCS 5/503, meaning assets are divided fairly but not necessarily equally. Unlike the 9 community property states that mandate a 50/50 split, Illinois courts consider 12 statutory factors to determine a just division. Courts may award one spouse 60% or more of marital assets if circumstances justify an unequal division.
Marital vs. Non-Marital Property
Under 750 ILCS 5/503(a), all property acquired during the marriage is presumed marital and subject to division. Non-marital property includes assets owned before marriage, inheritances received by one spouse, and gifts specifically given to one spouse. However, commingling non-marital funds with marital accounts can convert them to marital property.
The 12 Statutory Factors
Illinois courts consider these factors under 750 ILCS 5/503(d) when dividing property:
- Each party's contribution to acquisition or dissipation of marital property
- The value of property assigned to each spouse
- Duration of the marriage
- Economic circumstances of each spouse
- Obligations from prior marriages
- Prenuptial or postnuptial agreements
- Age, health, and employability of each spouse
- Custodial provisions for children
- Whether division is in addition to maintenance
- Future earning potential
- Tax consequences of distribution
- Each spouse's contribution as homemaker
Child Support and Custody Considerations
Illinois uses the Income Shares Model for calculating child support under 750 ILCS 5/505, basing obligations on both parents' combined net income. Child support guidelines are updated annually, with the most recent update in March 2025. The basic support obligation comes from a statutory schedule, and each parent pays their proportionate share based on income percentage.
Parenting Time and Decision-Making
Illinois replaced the terms "custody" and "visitation" with "allocation of parental responsibilities" and "parenting time" in 2016. Under 750 ILCS 5/602.5, courts allocate decision-making responsibility for education, healthcare, religion, and extracurricular activities based on the child's best interests. The parenting plan must detail the parenting time schedule, including regular periods, holidays, summer vacation, and transportation arrangements.
