How do I file for divorce in Palatine, Illinois?
To file for divorce in Palatine, you submit a Petition for Dissolution of Marriage to the Clerk of the Circuit Court of Cook County, pay the $388 petitioner fee, and serve your spouse. Illinois mandates electronic filing through the Odyssey eFileIL system for most documents, so most Palatine petitions are filed online rather than at a counter.
The process runs in a predictable order. First, you confirm the 90-day residency requirement under 750 ILCS 5/401 is met by at least one spouse. Second, you prepare the petition stating irreconcilable differences as the sole grounds, since Illinois eliminated all fault grounds on January 1, 2016. Third, you e-file through eFileIL and pay $388 (or submit an Application for Waiver of Court Fees under Illinois Supreme Court Rule 298 if your household income is at or below 125% of federal poverty guidelines, roughly $18,500 for a single person in 2026). Fourth, you serve your spouse, who then files an Appearance and pays $181 to $251.
When both spouses agree on every issue, Cook County offers a Joint Simplified Dissolution that can be heard the same day it is filed if you qualify, with both parties appearing together. Couples with significant marital property, retirement accounts, or minor children generally do not qualify and proceed under the standard track. A Palatine divorce lawyer typically handles the petition drafting, e-filing, financial disclosures, and the prove-up hearing.
Where do I file for divorce in Palatine? (which courthouse)
Palatine residents file divorce cases at the Cook County Circuit Court's Third Municipal District courthouse, located at 2121 Euclid Ave, Rolling Meadows, IL 60008, about five miles southeast of downtown Palatine. The main court number is (847) 818-3000, and office hours run 8:30 a.m. to 4:30 p.m., Monday through Friday. Parking is free in the garage on the building's west side.
Venue in Illinois follows residence. Under 750 ILCS 5/104, proceedings take place in the county where either party resides, so a Palatine resident's case is properly venued in Cook County and assigned to the Third Municipal District serving the northwest suburbs. This district covers Palatine, Arlington Heights, Schaumburg, Hoffman Estates, Inverness, Mount Prospect, Rolling Meadows, and surrounding communities.
A practical note: while most domestic relations matters are heard in Rolling Meadows, certain centralized functions historically routed downtown to the Richard J. Daley Center, 50 West Washington St., Chicago. Most Palatine dissolution cases proceed in Rolling Meadows, but confirm your assigned courtroom on the eFileIL confirmation or with the Clerk before any hearing. The Rolling Meadows courthouse also operates a Children's Room in Room 221 for children from infancy to age 16, reachable at (847) 818-3198, useful for parents attending hearings without childcare.
How much does a divorce lawyer cost in Palatine?
A divorce lawyer in Palatine typically charges $250 to $450 per hour, with most local family attorneys billing against a retainer of $2,500 to $5,000. An uncontested Palatine divorce commonly runs $1,500 to $4,000 in total attorney fees, while a contested case with disputed property or parenting issues frequently reaches $7,000 to $20,000 or more depending on litigation length.
The court costs are separate from attorney fees. The petitioner pays $388 to file in Cook County, and the responding spouse pays an appearance fee of $181 to $251. When an uncontested couple files the Marital Settlement Agreement together with the Respondent's Appearance, the combined court cost can approach $639. Additional expenses arise in contested matters: a parenting-time evaluation under 750 ILCS 5/604.10, a guardian ad litem, business or real estate appraisals, and mediation each add fees.
Several factors drive the cost of a divorce lawyer in Palatine. The biggest is whether the case is contested. Disputes over the marital home, retirement accounts subject to a Qualified Domestic Relations Order, maintenance under 750 ILCS 5/504, or the allocation of parental responsibilities all increase hours.

How long does a divorce take in Palatine?
An uncontested divorce in Palatine often finalizes in 45 to 90 days once the 90-day residency requirement under 750 ILCS 5/401 is satisfied and both spouses have signed a Marital Settlement Agreement. Contested cases in Cook County typically take 6 to 18 months, and complex matters involving custody evaluations or business valuations can run longer.
Illinois does not impose a mandatory cooling-off period between filing and judgment. The frequently misunderstood 6-month rule is an evidentiary shortcut, not a waiting requirement: if spouses have lived separate and apart for six continuous months before the hearing, the court treats that as irrebuttable proof of irreconcilable differences. Spouses can satisfy this while living under the same roof, and in uncontested cases both parties may waive the period entirely by stipulating that irreconcilable differences exist.
The timeline depends heavily on docket scheduling at the Rolling Meadows courthouse and the complexity of the marital estate. Cases with minor children require an approved parenting plan addressing both decision-making and parenting time before judgment. A Joint Simplified Dissolution, available to qualifying childless couples with limited property and a short marriage, can be heard the same day it is filed, making it the fastest route in Cook County.
What are the residency requirements to file in Cook County?
To finalize a divorce in Cook County, at least one spouse must reside in Illinois for 90 consecutive days before the court enters judgment, per 750 ILCS 5/401(a). Only one spouse needs to meet this requirement, and a petition can be filed before the 90 days elapse as long as residency is satisfied by the time the judge signs the final order.
Military members stationed in Illinois for 90 days satisfy the same requirement. Venue is separate from residency: under 750 ILCS 5/104, the case proceeds in the county where either party resides, which places a Palatine resident's case in Cook County. If neither spouse lives in the county where the petition is filed, the petitioner must move for an order waiving the venue requirement.
Illinois divides property by equitable distribution under 750 ILCS 5/503, meaning the court divides marital assets in just proportions based on twelve statutory factors rather than an automatic 50/50 split. Non-marital property, including assets owned before marriage or received by gift or inheritance, is generally assigned back to the owning spouse. Decision-making authority over a child's education, health, and religion is allocated under 750 ILCS 5/602.5, while the parenting-time schedule is governed by 750 ILCS 5/602.7, both decided by the child's best interests.
