If you are searching for a Chicago divorce lawyer, your case will be filed in the Cook County Circuit Court's Domestic Relations Division. Chicago sits entirely within Cook County, so residents from Lincoln Park to Hyde Park to the Loop all file at the same downtown courthouse: the Richard J. Daley Center at 50 West Washington Street, Room 802. Illinois is a no-fault, equitable-distribution state, and the only ground for divorce is irreconcilable differences under 750 ILCS 5/401.
This page covers the local logistics for getting divorced in Chicago: which courthouse serves you, what it costs, how long it takes, and the residency rules under Illinois law. Every figure below was verified against the Cook County Clerk of the Circuit Court and the Illinois General Assembly in 2026.

How do I file for divorce in Chicago, Illinois?
To file for divorce in Chicago, you e-file a Petition for Dissolution of Marriage with the Clerk of the Circuit Court of Cook County and pay the $388 petitioner fee as of 2026. Illinois requires all divorce petitions to be electronically filed through the state e-filing system; in-person paper filing is no longer the standard method, though Room 802 of the Daley Center still accepts exempt filers.
After filing, your spouse must be served and given a chance to respond. In an uncontested case, the respondent files an Appearance ($251) and signs a Marital Settlement Agreement, and the two fees combine into a single $639 payment at e-filing. The final step is a prove-up hearing, which in Cook County is routinely held online. Self-represented filers can get free help at the Daley Center Legal Advice Help Desk in Room CL-29 on the Concourse Level.
Where do I file for divorce in Chicago? (which courthouse)
Chicago residents file for divorce at the Richard J. Daley Center, 50 West Washington Street, Room 802, Chicago, IL 60602, which houses the Cook County Domestic Relations Division (District 1). The office is open 8:30 a.m. to 4:30 p.m., Monday through Friday, and the division phone line is (312) 603-6300.
Because Illinois divorces are e-filed and prove-up hearings are held online, the physical courthouse matters less than it once did. Anyone in Cook County can have their case heard downtown at the Daley Center. The county also operates five suburban district courthouses in Skokie, Rolling Meadows, Maywood, Bridgeview, and Markham, but a spouse must live within that district to use it. For Chicago residents, the Daley Center is the default venue, conveniently located in the Loop near the CTA Clark/Lake and Washington stations.
How much does a divorce lawyer cost in Chicago?
A Chicago divorce lawyer typically charges $250 to $450 per hour, with most family law attorneys requiring an upfront retainer of $2,500 to $5,000. An uncontested divorce where both spouses agree on all terms commonly costs $1,500 to $4,000 in total legal fees, while a contested case involving disputed property, support, or parenting issues frequently runs $8,000 to $15,000 or more.
Court costs are separate from attorney fees. The Cook County petitioner filing fee is $388 in 2026, the respondent's appearance fee is $251, and Cook County Sheriff service costs $60 if the respondent must be formally served. Spouses who cannot afford these costs can file a Petition for Waiver of Court Fees (the "298 Petition") and may qualify if their income is at or below 125% of the federal poverty level or they receive an income-based public benefit. A fee-waiver hearing is required within 14 days of filing.
How long does a divorce take in Chicago?
An uncontested Chicago divorce can be finalized in roughly 4 to 8 weeks once all paperwork is complete, because Illinois imposes no mandatory waiting period and spouses can waive the 6-month separation rule by agreement. The court can enter judgment as soon as the 90-day residency requirement is met, which often runs concurrently with case preparation.
Contested cases take much longer, typically 8 to 18 months in Cook County, depending on the complexity of property division, maintenance, and parenting disputes. The 6-month separation provision under 750 ILCS 5/401 is frequently misunderstood: it is not a required wait but an evidentiary presumption that conclusively establishes irreconcilable differences in a contested case. Living "separate and apart" does not require separate homes; spouses can satisfy it while sharing a residence if they no longer function as a married couple.
What are the residency requirements to file in Cook County?
At least one spouse must have lived in Illinois for 90 days before the court can enter a divorce judgment, under 750 ILCS 5/401. Only one spouse needs to meet this requirement, and military members stationed in Illinois for 90 days qualify even if their permanent home is elsewhere.
The 90-day clock runs to the date of judgment, not the date of filing, so a Chicago resident can file a petition immediately upon establishing residency and let the period elapse while the case proceeds. To file specifically in Cook County rather than another Illinois county, at least one spouse must reside in Cook County. For most Chicago residents this is automatic, since the entire city falls within Cook County's boundaries.
How is property divided in a Chicago divorce?
Illinois divides marital property by equitable distribution under 750 ILCS 5/503, meaning assets and debts are split "in just proportions" based on statutory factors, not necessarily 50/50. Marital property includes most assets acquired during the marriage, while inheritances, gifts, and pre-marital property are classified as non-marital and stay with the original owner.
The court weighs factors such as the length of the marriage, each spouse's contributions, economic circumstances, and any dissipation of assets before dividing. Spousal maintenance, if awarded, follows the statutory guideline under 750 ILCS 5/504: 33.3% of the payer's net income minus 25% of the recipient's net income. A 2025 change under Public Act 103-967 now keeps maintenance accruing even while a payer is incarcerated, with arrears enforceable upon release.
How is custody handled for Chicago parents?
Illinois replaced "custody" with "allocation of parental responsibilities" in 2016, dividing decision-making and parenting time under 750 ILCS 5/602.5 and 750 ILCS 5/602.7 based on the child's best interests. Parents must file a proposed parenting plan within 120 days of any petition for allocation, and Cook County typically orders mediation to resolve disputes.
Decision-making covers four significant areas: education, health, religion, and extracurricular activities. Courts allocate parenting time without considering parental conduct that does not affect the child. A 2025 update clarified that relocation distance is measured by internet mapping using the shortest surface-road route, which matters for Chicago parents weighing a move within or outside the metro area.
