Divorce is different from injury law. The best family lawyers often win by keeping a case out of trial, protecting a business valuation, or negotiating a parenting schedule both parents can live with for years. The top 5 divorce lawyer in Chicago list below isn’t about who shouts loudest in court.
Chicago also has one of the busiest divorce dockets in the Midwest. Cook County’s Domestic Relations Division hears cases at the Daley Center, and judges there expect lawyers to come prepared with financial disclosures and realistic proposals.
Illinois Divorce at a Glance
- No-fault only: Since 2016, “irreconcilable differences” is the only ground for divorce in Illinois. Nobody has to prove cheating or cruelty.
- Residency: One spouse must have lived in Illinois for at least 90 days before the court can finalize a divorce.
- “Custody” is gone: Illinois now uses the term allocation of parental responsibilities, splitting decision-making and parenting time.
- Property: Illinois divides marital property equitably, which means fairly, not automatically 50/50.
- Maintenance formula: When combined gross income is under $500,000, spousal support usually follows a statutory guideline formula.
1. Schiller DuCanto & Fleck LLP
Few Chicago firms have shaped Illinois divorce law as directly as this one. Donald Schiller co-founded the firm with Joseph DuCanto in 1981 and was instrumental in creating the state’s no-fault Dissolution of Marriage Act. He died in October 2024, but the firm he built remains one of the largest in the country devoted only to family law.
In July 2026, Chambers ranked the firm Band 1 for high-net-worth matrimonial work in Illinois, its ninth straight year at the top. Managing Partner Meighan Harmon, Karen Pinkert-Lieb, and Jason Sposeep each earned individual Band 1 rankings.
Offices in Chicago, Lake Forest, and Wheaton cover the city, the North Shore, and DuPage County.
Worth a call if: you have substantial assets, a family business, or a contested divorce likely to reach trial.
2. Beermann LLP
Beermann’s story starts small. In 1958, Miles N. Beermann and Nathan B. Swerdlove opened a neighborhood office on Milwaukee Avenue. Today, the firm runs offices on North Clark Street downtown and in Bannockburn.
Best Lawyers ranked Beermann a Tier 1 family law firm in Illinois for 2026, its 16th consecutive year with that ranking. Crain’s Chicago Business also named it a 2026 “Best Place to Work.”
The firm’s practice range is unusually wide. Beyond divorce, it handles prenups, adoption, guardianships, same-sex custody disputes, and divorces involving athletes and celebrities.
Worth a call if: your divorce involves business ownership, public visibility, or LGBTQ family issues.
3. Berger Schatz
One detail few clients notice: Berger Schatz and Beermann work out of the same downtown tower, 161 North Clark Street, just a few floors apart. Berger Schatz holds Tier 1 rankings in Chicago for both family law and family law mediation in the 2026 Best Law Firms guide.
That dual ranking matters. Not every divorce needs a war. Some spouses want a skilled mediator, and others need a litigator ready to cross-examine a financial expert. Partner Michael Berger, licensed in Illinois since 1973, has lectured extensively on business valuation, goodwill, and challenging financial experts.
Worth a call if: you want mediation as an option, or your case turns on valuing a business.
4. Katz & Stefani, LLC
Co-founders Daniel R. Stefani and Andre Katz built this firm around high-net-worth divorce, representing both the wealthier spouse and the spouse with less financial control. That second group often gets overlooked. A stay-at-home parent may not even know what assets exist.
The firm focuses heavily on valuing closely held corporations and partnerships, a technical area where hidden income often surfaces. Stefani has been recognized in The Best Lawyers in America and named a top family law practitioner by Chicago magazine. The firm has offices in Chicago and Riverwoods.
Worth a call if: you suspect your spouse is undervaluing a business or hiding income.
5. Grund & Leavitt, P.C.
Grund & Leavitt works from North Dearborn Street in River North and concentrates on matrimonial litigation. David I. Grund, a DePaul law graduate, appears in The Best Lawyers in America 2026 for family law.
As a boutique, Grund & Leavitt suits clients who want a senior lawyer personally handling their file rather than passing it down a long associate chain.
Worth a call if: you want litigation experience with a more personal, boutique feel.
Litigation, Mediation, or Collaborative Divorce?
Before hiring anyone, decide what kind of process fits your situation:
- Mediation: A neutral helps both spouses reach agreement. It is usually cheaper and private.
- Collaborative divorce: Each spouse hires a lawyer, and everyone commits to settling without court.
- Litigation: Necessary when there is abuse, hidden assets, or a spouse who refuses to negotiate.
Ask any lawyer you interview which path they recommend, and why.
FAQs

Q2. How is spousal maintenance calculated in Illinois?
A: For couples earning under $500,000 combined, Illinois uses a guideline formula based on both spouses’ net incomes. Marriage length determines how long payments last.
Q3. Do I need a lawyer for an uncontested divorce in Chicago?
A: Not legally, but it helps. A lawyer can spot unfair terms on retirement accounts, taxes, or parenting time before you sign an agreement that becomes very hard to change.
