Getting divorced in Chicago can cost anywhere from a few hundred dollars to tens of thousands, depending on whether your case is simple and cooperative or heavily litigated. This guide breaks down the Chicago divorce filing fee, typical Chicago divorce attorney cost, and what to expect for uncontested, contested, and mediated divorces.

Average Cost of Divorce in Chicago

These estimates include attorney or mediator fees plus court costs.

Chicago Divorce Filing Fee

Every Illinois divorce begins with filing a Petition for Dissolution of Marriage in circuit court.

• Cook County filing fee: roughly $388 – $400 for the initial petition.

• Respondent filing fee: around $250 – $300 when the other spouse answers.

• Service fees: about $50 – $75 if a sheriff or process server delivers documents.

• Filing fees are set by the county clerk and can change annually, so check the Clerk of the Circuit Court of Cook County website before submitting forms.

• Low-income filers may request a fee waiver using Illinois form CIR-GF-60.

Chicago Divorce Attorney Cost

Attorney billing makes up most of the expense in contested cases. In 2025, the average family-law hourly rate in Chicago ranges from $325 to $550, with senior partners charging more. Retainers for moderately complex divorces typically start around $3,500 – $7,500, but can climb rapidly if discovery, depositions, or trial preparation are needed.

Tips to control attorney spend

• Hire counsel for limited scope (drafting, one hearing) instead of full representation.

• Negotiate hourly caps or flat-fee stages.

• Resolve smaller property or scheduling issues directly with your spouse before bringing in lawyers.

Uncontested Divorce in Chicago

If you and your spouse agree on property, support, and parenting arrangements, you can usually finalize an uncontested divorce for under $2,000, plus the filing fee. Couples often use online platforms like Divorce.com to prepare Illinois-specific forms and submit them to the Cook County clerk.

Uncontested filings move quickly—often within two to three months once both parties sign and the court schedules a brief prove-up hearing.

Chicago Divorce Mediation Cost

Mediation provides a structured but non-adversarial setting to resolve disagreements about parenting, support, or property division.

Private mediators in Chicago charge roughly $150 – $350 per hour.

Most couples complete mediation in 4 – 6 sessions, for a total of $3,000 – $7,500.

The Cook County Domestic Relations Division also offers court-approved mediators for parenting issues, sometimes at reduced rates.

Mediation can cut legal fees dramatically while keeping both parties in control of the outcome.

Contested Divorce in Chicago

When spouses can’t agree on key issues, litigation becomes necessary. A contested divorce involves formal discovery, financial disclosures, expert witnesses, and multiple hearings.

The Chicago contested divorce cost commonly runs $15,000 – $30,000 or more, depending on the number of contested topics and the attorneys involved. Business ownership, real-estate valuation, or maintenance disputes push the figure higher.

Ways to limit costs: exchange financial documents early, stipulate uncontested facts, and consider mediation for side issues while litigating only what’s essential.

Chicago Asset Division Cost

Illinois follows an equitable distribution model, meaning marital property is divided fairly—but not always 50/50.

Expenses that raise Chicago asset division cost include:

• Property appraisals: $400 – $1,200 each.

• Business valuations: $5,000 – $15,000+.

• Retirement account QDROs: $300 – $1,000 per plan.

• Forensic accountants: $150 – $400 per hour** for tracing separate vs. marital assets.

Using neutral experts or agreeing on a single appraiser can save thousands.

Chicago Custody Dispute Cost

When parenting time or decision-making is contested, additional costs arise:

Guardian ad litem or child representative: $1,500 – $5,000 +.

Custody evaluations: $3,000 – $7,000 +.

Parenting coordination or therapy referrals: $1,000 +.

Because Cook County requires mediation before trial on parenting issues, cooperative parents often resolve disputes sooner and at lower cost.
