Divorce papers in Illinois: every form, fee, and filing step

Last updated 2026-07-09

What divorce papers do you actually need in Illinois?

Every Illinois divorce starts with the same core set of papers. What you add on top depends on whether you have kids and what you own. The Illinois courts sort these into two buckets: forms that open your case and forms that close it.

To open a case, you need a Petition for Dissolution of Marriage (some counties call it the Complaint for Divorce), a Summons to serve on your spouse, a Domestic Relations Cover Sheet, and a Certificate of Dissolution. Have minor children? You also need a Parenting Plan and an Allocation Judgment for Parental Responsibilities. Have money or property? Both spouses complete a Financial Affidavit.

To close the case, you file a Marital Settlement Agreement (your written deal on everything from who keeps the house to how you split retirement accounts), a Proposed Judgment for Dissolution of Marriage (the order the judge actually signs), and, if children are involved, a Child Support Worksheet run under Illinois guidelines.

The Illinois Courts self-help center publishes all of these forms for free. ^[1] Download them, fill them out in any PDF reader, and print. None of them require an attorney to prepare. If your situation is tangled, though, a one-time consult with a divorce lawyer before you sign anything is money well spent.

Here's the piece people miss. Illinois also requires a Proof of Service or an Acceptance of Service form once your spouse gets the papers. Without that filed with the clerk, your case sits dead. Plan for it from day one.

What are the residency and grounds requirements before you can file?

Two rules gate every Illinois divorce. Clear both and a judge will hear your case. Miss either and you wait.

At least one spouse must have lived in Illinois for 90 days right before filing. ^[2] That's a hard line. Just moved here? Wait out the 90 days. Your spouse lives in Illinois but you don't? They can file.

The second rule is grounds. Illinois is a pure no-fault state, and since 2016 the only ground is "irreconcilable differences." The Illinois Marriage and Dissolution of Marriage Act (750 ILCS 5/401) says a court shall dissolve a marriage when it finds that "irreconcilable differences have caused the irretrievable breakdown of the marriage." ^[2] You don't allege fault. You don't prove it. If both spouses agree, you don't need any separation period at all. If only one spouse wants out, Illinois presumes irreconcilable differences after the two of you have lived apart for six months.

Those two rules cover nearly everyone reading this. Military status or a pending bankruptcy adds procedural layers, so confirm those with the clerk's office before you file.

How much does it cost to file divorce papers in Illinois?

Filing fees are set county by county and change on their own schedules, so a number you saw on a forum two years ago is probably stale. Budget somewhere between $289 and $388 for the initial filing.

Cook County (Chicago) charges $289 for a dissolution filing on its current published schedule. ^[3] Collar counties like DuPage, Lake, and Will usually land between $300 and $388. Some downstate counties run lower. Your county clerk has the exact current figure.

The filing fee is just the start. Here's what else shows up:

Cost item	Typical range
Filing fee (petitioner)	$289 to $388
Service by sheriff or process server	$25 to $65 per attempt
Certified copies of final decree	$2 to $9 per page
Parenting class (required if minor children)	$25 to $75 per parent
Financial Affidavit notarization	$5 to $15

Can't afford the filing fee? Illinois lets you file an Application for Waiver of Court Fees (form CCG0201 in Cook County, with equivalents elsewhere). ^[3] The court waives fees for people at or below 125% of the federal poverty level.

None of that table counts attorney fees. A contested Illinois divorce averages $11,000 to $13,000 according to Martindale-Nolo survey data. ^[4] Handle an uncontested case yourself and that number drops to zero. For the full spending picture, see our general divorce papers guide.

Where do you file divorce papers in Illinois?

You file in the Circuit Court of the county where either spouse lives. ^[2] Illinois has 102 counties, each with its own Circuit Court clerk. Live in Cook County while your spouse lives in Champaign County? You pick. Most people file where they live because it's simpler.

Almost every circuit court now takes e-filing through the state portal, eFileIL. ^[5] You make an account, upload your completed PDFs, pay by credit card, and the clerk processes everything electronically. The system works. It is not pretty. Give yourself extra time the first time through.

Prefer to file in person? Bring two copies of every document. One gets stamped and handed back to you as your filed copy. The other goes in the court file. Some clerks still want paper originals for certain forms, so call ahead.

Once you file, the clerk assigns a case number and returns a stamped Summons. That stamped Summons, plus a copy of the Petition, is what you serve on your spouse.

How do you serve divorce papers on your spouse in Illinois?

Service is the formal delivery of the Summons and Petition to your spouse, and you cannot do it yourself. The Illinois Code of Civil Procedure (735 ILCS 5/2-203) requires personal service for initial divorce filings. ^[6] Someone other than you has to hand the papers directly to your spouse.

You have three practical options.

1. Sheriff's service. Pay the county sheriff (usually $25 to $60) to serve your spouse. This is the default and creates an automatic official record.

2. Private process server. A licensed server often moves faster than the sheriff, which helps if your spouse is hard to pin down. Expect $40 to $100 depending on location and number of attempts.

3. Acceptance of service. If your divorce is genuinely uncontested and your spouse cooperates, they sign an Entry of Appearance and Waiver of Service. No formal serve, no waiting. Both of you sign, the form gets filed, and you move on. This is the fastest path by far.

After service (or a signed waiver), your spouse has 30 days to file a response if they want to contest anything. In an uncontested divorce, they usually file an Entry of Appearance showing they agree, or simply sign the final documents.

Service by publication (running a notice in a newspaper) is a last resort. It's only available when you genuinely cannot locate your spouse after documented, diligent effort, and the court has to approve it first.

What goes in a Marital Settlement Agreement in Illinois?

The Marital Settlement Agreement is the heart of your uncontested divorce. It's a private contract between you and your spouse that the judge reviews and, if it passes, folds into the final decree. Get the MSA right and everything after it is paperwork.

An Illinois MSA has to settle every marital issue. Real estate (who keeps the house, or how you sell it and split the proceeds). Every bank and investment account. Retirement accounts (a 401(k) or pension needs a separate Qualified Domestic Relations Order to divide). Vehicles. Personal property. Debts. It also has to address spousal support (Illinois calls it maintenance) or explicitly waive it.

With minor children, the MSA or a separate Allocation Judgment must spell out parental decision-making and a residential schedule. Illinois dropped the word "custody" in 2016; the statute now uses "parental responsibilities" and "parenting time." ^[2] Child support has to follow the Illinois Income Shares model, calculated on the official Child Support Worksheet. A judge cannot approve an MSA that departs from the guidelines without written findings explaining why.

Illinois courts check MSAs to make sure they aren't "unconscionable," meaning one spouse isn't getting wildly shortchanged. A roughly fair split sails through. Lopsided terms draw questions, and sometimes a short hearing.

The MSA has to be signed by both spouses, notarized, and filed with your other closing documents.

What is the process timeline from filing to final decree?

Illinois has no mandatory waiting period for an agreed no-fault divorce with no minor children. On paper, a judge could sign your decree the same day you file if the court has room and every form is clean. In real life, plan on 30 to 90 days for a simple agreed case.

Here's a realistic sequence.

Week 1: Complete and file your opening documents. Pay the filing fee.

Week 2 to 3: Serve your spouse, or get a signed Acceptance of Service the same day if they cooperate.

Week 3 to 6: Both spouses finalize and sign the MSA and the rest of the closing documents.

Week 4 to 10: File the closing documents. The clerk schedules a short prove-up hearing. In Cook County, uncontested cases can do this by affidavit with nobody appearing in court.

Week 6 to 12 (sometimes longer): The judge reviews and signs the Judgment for Dissolution of Marriage. You're divorced.

With minor children, Illinois requires both parents to finish a parenting education program before the final hearing. ^[7] Most run about four hours and cost $25 to $75. Knock it out early or it adds weeks.

Backlog swings by county. Cook County moves slower than rural courts. File in a busy urban court and 90 days is realistic. Small downstate counties sometimes wrap in 30.

Do you have to go to court for an uncontested divorce in Illinois?

Sometimes yes, sometimes no. It comes down to your county and the shape of your case.

Cook County lets you finish an uncontested dissolution without ever showing up if you file a properly notarized Affidavit in Lieu of Prove-Up Hearing with your closing documents. ^[8] The judge reviews the file and signs in chambers. Your decree arrives by mail or through the e-filing portal.

Many other Illinois counties still want at least one short hearing, the prove-up. It runs five to fifteen minutes. One or both spouses stand before the judge, confirm under oath that the agreement is fair and voluntary, and the judge grants the divorce. Some counties require both spouses. Others only need the petitioner.

Check the self-help page for your specific circuit court before you assume you can skip the hearing. The Illinois Courts website keeps a county-by-county directory. ^[1]

With minor children, most counties want at least one parent at the prove-up even in fully agreed cases, though local practice varies.

How do you fill out the Illinois divorce forms without making mistakes?

The forms aren't hard once you see what each one asks. The mistakes that blow up uncontested cases fall into a few predictable buckets, and you can dodge all of them.

Caption errors. Every form has a caption at the top with the county, case number, and party names. The petitioner is whoever filed. The respondent is the other spouse. Swap those and your documents bounce.

Inconsistency between documents. Your MSA says you keep the Toyota. Your Proposed Judgment says your spouse keeps it. The clerk or judge catches it and sends everything back. Write the MSA first, then copy the exact same facts into the Judgment and every other form.

Missing notarization. Both the Financial Affidavit and the MSA require notarization in Illinois. Banks notarize for free. UPS and FedEx stores charge a small fee. Do it before you file.

Child support math. The Illinois Department of Healthcare and Family Services publishes the Income Shares guidelines and the worksheet you have to complete. ^[9] Run the numbers slowly. A support figure that doesn't match the worksheet draws a judge's question at best and a rejection at worst.

Want a pre-checked starting point? Services like DivorceClear sell a complete Illinois document packet for $149 that builds all the forms from your answers and flags inconsistencies before you print. That's a reasonable middle ground between blank PDFs and hiring a lawyer.

Whatever you use, read every form after you fill it out. Then read it again. The clerk can't give you legal advice, and a rejected filing costs you the one thing you're trying to save: time.

What happens to property and debt in an Illinois divorce?

Illinois is an equitable distribution state, not a community property state. ^[2] Marital property gets divided fairly, which is not always down the middle. Courts weigh the length of the marriage, each spouse's contribution, economic circumstances, and whether children will live mostly with one parent.

In an uncontested divorce, you and your spouse decide the split yourselves in the MSA. The judge checks it for basic fairness but generally signs off on what the two of you agreed to voluntarily. That's the biggest advantage of going uncontested: you control the outcome instead of handing it to a judge.

Marital property is nearly everything acquired during the marriage. Gifts and inheritances one spouse received stay separate as long as they were kept separate. The family home, joint accounts, retirement contributions made during the marriage, and most vehicles are marital.

Debt follows the same logic. Credit card balances run up during the marriage are marital debt. Your MSA should name who pays what. Watch this closely: even if your MSA says your spouse pays the Visa, the bank can still come after you if the account is in your name and your spouse doesn't pay. Get accounts transferred out of your name after the divorce is final wherever you can.

Retirement accounts need extra care. A Qualified Domestic Relations Order (QDRO) is a separate court order that actually divides a 401(k) or pension without triggering early withdrawal taxes. ^[10] Your MSA should reference the QDRO. The QDRO itself gets drafted and submitted after the decree is entered. Many plan administrators have their own QDRO forms. Build time into your plan if retirement money is in play.

What about child custody and support in Illinois divorce papers?

Illinois scrapped the words "custody" and "visitation" in 2016 when it rewrote the Illinois Marriage and Dissolution of Marriage Act. ^[2] The current setup splits parenting into two parts: allocation of parental responsibilities (who decides on education, health, religion, and activities) and parenting time (the actual schedule of when each parent has the child).

Your Parenting Plan has to cover both, in detail. A judge won't approve a vague plan. "We'll figure it out" is not a parenting plan. You need specific days, holidays, school breaks, and a protocol for handling changes.

Illinois uses the Income Shares model for child support, so both parents' incomes feed the calculation. ^[9] The Illinois Department of Healthcare and Family Services keeps the schedule of basic support obligations and the worksheet. You can run the math yourself off their published tables.

Changing child support later takes a substantial change in circumstances, like a 20% or greater swing in income. Keep your records.

Where can you get free help with Illinois divorce papers?

Illinois has several free resources that are genuinely good, and you should use them.

The Illinois Courts self-help center at illinoiscourts.gov has downloadable forms, plain-language instructions, and a self-represented litigant section the state keeps current. ^[1] Start there.

Illinois Legal Aid Online (illinoislegalaid.org) has guided interview tools that walk you through the divorce forms one question at a time and generate completed PDFs. ^[11] Free, top to bottom. Their uncontested divorce coverage is solid.

Many Illinois circuit courts run self-help centers or law libraries staffed by people who answer procedural questions. They can't give legal advice, but they can point you to the right forms and tell you whether you filled something out correctly. Cook County's Daley Center has a dedicated self-help desk.

If your income is low, Prairie State Legal Services, Land of Lincoln Legal Aid, and LAF (Legal Assistance Foundation) offer free or low-cost help to qualifying residents. ^[12]

Frequently asked questions

Can I file for divorce in Illinois without a lawyer?

Yes. Illinois law does not require an attorney for divorce. If your divorce is uncontested and both spouses agree on all terms, you can prepare and file the paperwork yourself using forms from the Illinois Courts self-help center. The main risk of going solo is paperwork errors or gaps in the agreement that a judge won't approve. With straightforward finances and no contested issues, self-filing is realistic.

How long does an uncontested divorce take in Illinois?

A simple uncontested divorce with no children usually takes 30 to 90 days from filing to final decree in Illinois. Cook County runs slower because of case volume; rural counties move faster. There is no mandatory waiting period for an uncontested no-fault divorce. Your speed depends on how fast you serve your spouse, complete the paperwork, and get a court date or affidavit slot.

What is the filing fee for divorce in Illinois?

Filing fees vary by county. Cook County charges $289 on its current published schedule. Most other Illinois counties fall between $300 and $388. Add service fees ($25 to $65), notarization, and parenting class fees if you have minor children. If you can't afford the fee, apply for a fee waiver using the court's Application for Waiver of Court Fees, granted at or below 125% of the federal poverty level.

Does Illinois require separation before divorce?

No, not if both spouses agree the marriage is over. Illinois eliminated mandatory separation periods for agreed no-fault divorces in 2016. If only one spouse wants the divorce and the other contests it, Illinois presumes irreconcilable differences after six months of living separate and apart. In an uncontested case where both parties consent, you can file and proceed right away.

What forms do I need to file for divorce in Illinois with no kids?

For a no-children uncontested divorce you need: Petition for Dissolution of Marriage, Summons, Domestic Relations Cover Sheet, Financial Affidavit (both spouses), Marital Settlement Agreement, Proposed Judgment for Dissolution of Marriage, and Certificate of Dissolution. In Cook County you may also file an Affidavit in Lieu of Prove-Up Hearing to skip a court appearance. All forms are free from the Illinois Courts website.

How do I serve divorce papers in Illinois?

You cannot serve the papers yourself. Illinois requires personal service by someone other than you, typically the county sheriff ($25 to $60) or a licensed private process server ($40 to $100). If your spouse cooperates, they can sign an Entry of Appearance and Acceptance of Service instead, which skips formal service. Service by publication in a newspaper is a last resort, only allowed when your spouse genuinely cannot be located.

Can I get a divorce in Illinois if my spouse won't sign the papers?

Yes. If your spouse refuses to respond after being properly served, you can file for a default judgment. Your spouse has 30 days after service to respond. If they don't, you file a Motion for Default, and the court can grant the divorce on your petition alone. A spouse who actively fights the proceedings is a different situation and will almost certainly require an attorney.

Do both spouses have to appear in court for an Illinois divorce?

Not always. Cook County allows uncontested divorces to be finalized by notarized affidavit with neither party appearing in court. Many other Illinois counties require at least a brief prove-up hearing. If children are involved, most judges want at least one parent to appear. Check your county's circuit court to confirm current local rules before assuming you can skip the hearing.

How is property divided in an Illinois divorce?

Illinois uses equitable distribution, so marital property is divided fairly but not necessarily 50/50. In an uncontested divorce, you and your spouse decide the split yourselves in a Marital Settlement Agreement, and the judge reviews it for basic fairness. Property acquired before the marriage, or received as a gift or inheritance during it, is generally separate property and stays with the original owner.

How is child support calculated in Illinois?

Illinois uses the Income Shares model, which factors in both parents' net incomes, the number of children, and the parenting time schedule. The Illinois Department of Healthcare and Family Services publishes a schedule of basic support obligations and a required Child Support Worksheet. You must complete the worksheet and attach it to your filing. Amounts that deviate from the guidelines require written findings from the judge.

What is a Qualified Domestic Relations Order and do I need one?

A QDRO is a separate court order that tells a retirement plan administrator to divide a 401(k), 403(b), or pension between spouses without triggering early withdrawal taxes. You need one to divide any employer retirement account. It's prepared after the divorce decree is entered, not before. Your MSA should reference the planned QDRO. Each plan has its own rules, so contact the administrator early.

Where do I file for divorce in Illinois if my spouse lives in a different county?

You can file in the circuit court of the county where you live or the county where your spouse lives. Illinois law allows either. Most people file in their own county for convenience. If you're unsure which county has jurisdiction, or there are complications like property in multiple counties, call the clerk's office before you file to save time.

What is the difference between legal separation and divorce in Illinois?

A legal separation in Illinois is a court order that defines the rights and responsibilities of spouses living apart but not divorced. You stay legally married. It can address property, support, and parenting, and some couples choose it for insurance, religious, or financial reasons. It takes similar paperwork to a divorce but ends with a Judgment of Legal Separation instead of a Judgment for Dissolution of Marriage.

Can I use online divorce forms for Illinois or do I need a service?

You can use the free forms directly from the Illinois Courts website or Illinois Legal Aid Online, which has a guided interview that generates completed PDFs at no cost. Paid document services help if you want forms pre-checked for consistency and completeness, but they aren't required. The state's free resources are genuinely adequate for a straightforward uncontested case with a cooperative spouse.
