Chicago Divorce Papers: Forms, Filing & Cost (2026)

Filing for divorce in Chicago, IL starts with a stack of paperwork. The exact forms depend on Illinois statute, but every uncontested case needs the same core packet: a petition, a settlement agreement, financial disclosures, and a proposed decree.

This guide walks through every form a Chicago divorce requires, where to get it, how to fill it out, and the most common mistakes that send a packet back from the Cook County Circuit Court clerk.

The Chicago Divorce Paperwork Checklist

The Illinois court system has a defined set of divorce forms. For an uncontested Chicago filing, you'll need:

• Petition for Dissolution of Marriage — this is what starts the case officially. Includes both spouses' information, Illinois residency facts, the no-fault basis, and the relief requested.

• Marital Settlement Agreement — the contract that resolves property, debts, support, and (if applicable) custody. The court turns this into the final order.

• Financial Disclosure Forms — required by Illinois to confirm both spouses have shared full income, asset, and debt information. Format varies; most states use a standardized financial affidavit.

• Summons — the notice served on the responding spouse (skipped when filing jointly or with a waiver of service).

• Parenting Plan + Child Support Worksheet — required when minor children are involved. Spells out custody, parenting time, decision-making, and the calculated child support number.

• Proposed Judgment for Dissolution of Marriage — the order the judge will sign at the end. You draft it; the court approves it.

Many Illinois counties layer on local forms (case information sheets, child-related notices, service contact forms). Always confirm the local addenda with the Cook County Circuit Court clerk before submission.

Where to Download Chicago Divorce Forms

You can get the Illinois divorce packet from three sources, in order of cheapest-to-most-convenient:

• The Illinois courts website (free). Every required form is published as a fillable PDF. You'll need to identify the correct forms for your situation, download them, and fill them out yourself.

• The Cook County Circuit Court self-help center (free). Many Illinois courthouses staff a self-help clerk who can hand you a paper packet and answer non-legal questions about which forms apply.

• Online divorce services like Divorce.com™ (flat fee). The service prepares the entire packet from a guided questionnaire, so you never see a blank state form. Saves the most time; not free.

Don't grab forms from non-court websites. Anything not from the official Illinois courts site (or a service that sources from it) is likely outdated or wrong-county. Rejected packets cost weeks.

Completing Your Chicago Divorce Forms Without an Attorney

Illinois divorce forms are unforgiving. The Cook County Circuit Court will bounce back any packet with the wrong date format, a missing signature, or inconsistent financial figures. Some practical guidance:

• Use legal names, not nicknames. The name on the petition has to match the name on your marriage certificate and on every supporting document.

• State the Illinois residency requirement on the petition. 90 days in Illinois. The petition typically requires a sworn statement that you meet it.

• Cite the no-fault ground. Illinois is no-fault; the only ground is irreconcilable differences. An uncontested filing should reference this language directly.

• Match dollar amounts across forms. The financial affidavit, settlement agreement, and (if applicable) child support worksheet should all reconcile — clerks check for this.

• Sign and date in front of a notary where required. Several forms — settlement agreements, financial affidavits — require notarized signatures. Don't sign in advance.

• Don't leave any field blank. Write "N/A" or "None" rather than skipping a question. Blanks are interpreted as incomplete forms.

Submitting Chicago Divorce Papers to the Court

Your packet goes to Cook County Circuit Court. Illinois supports e-filing through Illinois eFileIL (efile.illinoiscourts.gov), so most Chicago filers submit electronically rather than walking the papers into the clerk.

• Filing fee: approximately $285–$388, paid at submission. Illinois accepts fee waiver applications for filers under income limits.

• E-filing system: Illinois eFileIL (efile.illinoiscourts.gov). Most Illinois counties now accept the full divorce packet electronically.

• Paper filing alternative: still available in most counties for filers who prefer to walk the packet into the clerk's office.

Next Steps Once Your Chicago Papers Are Filed

Submitting the divorce papers starts the case — it doesn't finish it. The remaining sequence:

• Service on the responding spouse — accomplished by Acceptance of Service (signed by the spouse), by sheriff, or by process server. Skipped entirely for joint petitions in counties that allow them.

• Illinois waiting period — no statutory waiting period for uncontested cases. Used to finalize the settlement agreement and exchange any required financial disclosures.

• Submission of the signed settlement + proposed decree — after the wait expires. Most uncontested cases are decided on the documents without a hearing.

• Certified copies of the Judgment for Dissolution of Marriage — issued by the clerk after the judge signs. Order multiple; you'll need them for DMV, banks, retirement accounts, and beneficiary updates.

Why Illinois Divorce Papers Get Rejected

Most Chicago divorce papers are rejected for the same handful of reasons. Avoid these and your packet typically clears on the first review:

• Missing signature or notary block. The most common single rejection reason. Every signature line needs to be completed; notary stamps need to be present on forms that require them.

• Inconsistent financial figures. If the income on your financial affidavit doesn't match the income on the child support worksheet, the clerk will catch it.

• Using outdated form versions. State courts revise forms periodically. Always download from the official site within a few days of filing.

• Wrong court/wrong venue. Filings need to go to the correct Illinois court for your county of residence. The Cook County Circuit Court handles Chicago divorce cases.

• Incomplete settlement agreement. The agreement should resolve every issue — property, debts, support, custody (if applicable). Vague language gets bounced back.

• Wrong filing fee. Fees change. Check the current schedule at the clerk's office before submitting.
