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

Filing for divorce in Naperville, 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 Naperville divorce requires, where to get it, how to fill it out, and the most common mistakes that send a packet back from the DuPage County Courthouse (18th Judicial Circuit) clerk.

Illinois Divorce Forms: The Required Packet

Every uncontested Naperville divorce uses the same core forms. The names vary by Illinois statute, but the function is identical state to state:

• Petition for Dissolution of Marriage — the foundation document — identifies the parties, asserts Illinois jurisdiction, states the no-fault ground, and asks the court to grant the divorce.

• Marital Settlement Agreement — the binding agreement between spouses covering property division, debts, support, and custody if children are involved. The court incorporates it into the final decree.

• 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 proposed final order. You write what you want the court to rule; the judge reviews and signs.

Local rules add a few forms in most Illinois counties — case info sheets and child-related notices being the most common. The DuPage County Courthouse (18th Judicial Circuit) clerk's checklist is the definitive list.

Where to Get Illinois Divorce Papers

Illinois divorce forms are free, public documents. You have three places to get them:

• 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 DuPage County Courthouse (18th Judicial Circuit) 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.

Avoid generic "divorce form" downloads from random websites — they're often outdated, missing local addenda, or formatted for the wrong state. The DuPage County Courthouse (18th Judicial Circuit) clerk will reject these.

How to Fill Out Illinois Divorce Papers

Illinois divorce forms are unforgiving. The DuPage County Courthouse (18th Judicial Circuit) 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.

After You File: Service, Settlement, Decree

Once DuPage County Courthouse (18th Judicial Circuit) accepts your packet, the case is officially open. From there:

• 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.

Mistakes That Send Your Naperville Papers Back

The DuPage County Courthouse (18th Judicial Circuit) bounces back roughly the same set of mistakes from every DIY filer. Watch for:

• 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 DuPage County Courthouse (18th Judicial Circuit) handles Naperville 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.
