Will County Divorce: Filing, Costs, and Prove-Up Hearing

To get a Will County divorce, you file a Petition for Dissolution of Marriage in the 12th Judicial Circuit Court through the statewide eFileIL system, pay a $603 filing fee, serve your spouse, and finish with a prove-up hearing before a judge at the Will County Courthouse in Joliet. At least one spouse must have lived in Illinois for 90 days before filing, and Illinois recognizes only one ground: irreconcilable differences.

Who Can File in Will County

Two separate rules decide whether you can file here. The first is residency: one spouse must have lived in Illinois continuously for at least 90 days before the petition is filed.¹ Military members stationed in Illinois count even if they consider another state their permanent home.

The second is venue, which asks which county. Illinois requires the case to be filed in the county where the petitioner or respondent lives.² If either spouse lives in Will County, you can file there. A venue objection has to be raised early or it’s waived for good.

The Only Ground: Irreconcilable Differences

Illinois is a pure no-fault state. The only ground for divorce is that irreconcilable differences have caused an irretrievable breakdown of the marriage.¹ You don’t prove adultery, abandonment, or anything else. The court only needs to find the marriage is beyond repair.

If both spouses have lived separately for at least six continuous months before the judgment is entered, the court treats the irreconcilable-differences requirement as automatically met.¹ Separately doesn’t have to mean different houses; separate bedrooms within the same home can qualify. When both spouses agree the marriage is over, that six-month period can be waived, which lets an uncontested case move faster.

What It Costs to File

The total filing fee in Will County is $603: $364 for the petition and $239 for the appearance.³ Service of process is separate; the Will County Sheriff’s Office charges between $52 and $91 depending on where the respondent is served.⁴ A licensed private process server is the other option.

If you can’t afford the fee, Illinois provides a waiver based on income. A full waiver is available if your income is at or below 125% of the federal poverty level, with partial waivers of 25% to 75% for incomes up to 200%. You qualify automatically if you receive SNAP, SSI, or TANF.⁵

Documents You’ll Need

Pull your financial records before you file. Delays almost always trace back to missing paperwork. Gather:

Recent pay stubs, W-2s, and federal and state tax returns from at least the last three years.
Checking, savings, brokerage, and money market statements for the past 12 months.
Statements for every 401(k), IRA, and pension, with current balances and plan details.
Deeds, mortgage statements, and recent property tax assessments for any real estate.
Credit card, auto loan, student loan, and other debt statements with interest rates.
Policy pages for life, health, auto, and property insurance, showing beneficiaries and premiums.
Signed copies of any prenuptial or postnuptial agreement.

The court forms themselves are standardized statewide and available from the Illinois Courts.⁶ You’ll complete the Petition for Dissolution of Marriage, which sets out what you’re asking for; a Summons to notify your spouse; and a Financial Affidavit, a sworn breakdown of your income and monthly expenses. Names must match your identification exactly, property descriptions should be specific, and the Financial Affidavit expects a line-by-line monthly accounting. Judges read these closely, and inconsistencies push cases back weeks.

Filing and Serving Your Spouse

All civil filings in Will County go through the statewide eFileIL system.⁷ You create an account, upload signed PDFs, and select the filing codes for Will County.

Once the clerk accepts your filing, your spouse must be formally served with copies of the Summons and Petition. The sheriff or a private process server delivers them, and a return-of-service document confirming delivery is filed with the court. Without that proof on file, nothing else in the case can move.

A Faster Path for Qualifying Couples

Illinois offers a streamlined process called joint simplified dissolution for couples who fit a narrow set of criteria. All of these must be true:

No children were born or adopted during the marriage, and the wife is not pregnant.
The marriage lasted eight years or less.
Total marital property, after debts, is worth less than $50,000, and neither spouse owns real estate or retirement benefits (except IRAs worth less than $10,000 combined).
Combined gross income is under $60,000 per year, and neither spouse individually earns more than $30,000.
Both spouses waive maintenance.
Both have shared all asset, debt, and tax information and have a written agreement dividing everything worth more than $100.

Both spouses have to appear together to file the petition.⁸ One trade-off is worth knowing before you choose this path: a judgment entered through simplified dissolution cannot be appealed. If you later regret the property split or wish you’d asked for maintenance, you have no recourse.

How Property Gets Divided

Illinois follows equitable distribution. The court divides marital property fairly but not necessarily equally. Non-marital property (what you owned before the marriage or received as gifts or inheritance) is set aside first; everything else is divided based on a list of factors.⁹

The factors that carry the most weight include each spouse’s contribution to acquiring or preserving the property (including contributions as a homemaker), the length of the marriage, each person’s economic circumstances, and age, health, and earning capacity. Marital misconduct is explicitly excluded from the property analysis. If one spouse wasted marital assets while the marriage was breaking down, the court can account for that dissipation in the split.

Maintenance (Spousal Support)

Illinois uses a statutory formula in most cases. Maintenance equals 33⅓% of the paying spouse’s net annual income minus 25% of the receiving spouse’s net annual income, but the receiving spouse can’t end up with more than 40% of the couple’s combined net income.¹⁰

Duration is tied to the length of the marriage through a statutory multiplier. A 5-year marriage uses 0.24 (about 1.2 years of maintenance); a 15-year marriage uses 0.64 (about 9.6 years). For marriages of 20 years or more, the court can order maintenance for the length of the marriage or indefinitely.¹⁰ Judges can deviate from the formula if applying it would be unjust.

Child Support

Illinois uses an income shares model. Both parents’ incomes are combined, a support amount is calculated based on the combined income and the number of children, and each parent’s share is proportional to their share of that combined income.¹¹ The Illinois Department of Healthcare and Family Services publishes the worksheets. The guideline amount is presumptively correct, but judges can adjust it based on the child’s needs, educational requirements, or the standard of living the child would have had.

Parenting Class and Standing Orders

When minor children are involved, both parents must complete an approved parenting education program before the court will enter a final judgment. The 12th Judicial Circuit requires this under local Rule 8.05, and the Will County Circuit Clerk maintains the list of approved providers, including an online option through the Center for Divorce Education.¹² File the certificate of completion with the clerk early. Judges check for it before signing the judgment, and forgetting it stalls your case at the finish line.

When the case is filed, the court also issues standing orders that freeze the status quo. Neither spouse can hide assets, change insurance beneficiaries, or remove children from the state without the other’s consent or a court order. Violating a standing order invites sanctions and damages your credibility with the judge.

The Prove-Up Hearing

Every Will County divorce ends with a prove-up hearing before the assigned judge. If both spouses have reached agreement, the hearing is short. The petitioner testifies under oath to confirm residency, the date of marriage, that the relationship has broken down, and that the terms of the proposed judgment are understood and fair.

You schedule the hearing through the case coordinator for your assigned judge at the Will County Courthouse, 100 West Jefferson Street in Joliet. Before the hearing, the proposed Judgment of Dissolution of Marriage needs to be drafted and ready for the judge’s signature. That single document carries every order on property, maintenance, child support, and parenting. Once the judge signs, the marriage is legally dissolved. If the respondent never answered, the court can enter a default judgment and the hearing focuses on jurisdiction and basic facts. Get a certified copy of the signed judgment from the clerk; you’ll need it to change your name on identification, update beneficiaries, and prove the marriage ended.

Loose Ends People Miss

A few things catch people after the judgment is signed, and the deadlines on some of them are tight.

Health insurance. If you’re on your spouse’s employer plan, divorce ends that coverage. Federal law lets a divorced spouse continue coverage through COBRA for up to 36 months, but you or a qualified beneficiary must notify the health plan within 60 days of the divorce.¹³ Unlike other qualifying events, this notice is on you, not the employer. Miss the 60-day window and you lose COBRA entirely, with no appeal.

Retirement accounts. Private retirement plans governed by ERISA require a Qualified Domestic Relations Order (QDRO) before the plan administrator can pay benefits to a former spouse.¹⁴ Without a valid QDRO, the plan can only pay the participant, no matter what your decree says. The QDRO has to be reviewed and approved by that specific plan’s administrator under its own rules.¹⁵ Get it drafted and qualified before the divorce is finalized; fixing it afterward is much harder. Government pensions and church plans follow different rules because ERISA doesn’t cover them.

Social Security. If your marriage lasted at least 10 years, you may be eligible to collect Social Security on your ex-spouse’s record. You must be at least 62, currently unmarried, and not entitled to a higher benefit on your own record.¹⁶ If your ex hasn’t filed yet, you also need to have been divorced for at least two years. Claiming on an ex-spouse’s record doesn’t reduce their benefit or their current spouse’s. If you’re close to the 10-year mark, the timing of your filing matters.

Taxes. For any divorce agreement executed after December 31, 2018, the paying spouse cannot deduct maintenance and the receiving spouse does not report it as income.¹⁷ Older agreements still follow the previous rules unless formally modified. For couples with children, the custodial parent (the one the child lives with more than half the year) generally gets the child tax credit, head of household status, the dependent care credit, and the Earned Income Tax Credit. The custodial parent can sign a written declaration letting the noncustodial parent claim the dependency exemption and child tax credit, but the EITC and head of household status stay with the custodial parent regardless.¹⁸ A settlement that says you’ll alternate claiming the child each year does not override the residency rule for the EITC.
