Our approach
Steady counsel for a difficult transition.
Ending a marriage involves legal questions and personal ones at the same time. Illinois law sets the framework—where you can file, how property is divided, how parental responsibilities are allocated, and how support is calculated—but how those rules apply depends on the facts of your family.
Our aim is to explain your options plainly, help you understand what the Illinois Marriage and Dissolution of Marriage Act requires, and pursue a resolution that fits your priorities, whether that is a negotiated agreement or a matter that needs to be presented to a judge.
Illinois Divorce & Family Law is a practice of Tanner-Flomberg Law Group, based at 448 N La Salle Dr, Floor 9, Chicago, IL 60654. We work with clients throughout Illinois, often through virtual consultations, subject to conflict checks, the scope of the matter, attorney availability, and any in-person court appearances a case may require.

How Illinois divorce generally works
A typical path, from first questions to judgment
- 01
Eligibility
At least one spouse must meet Illinois's 90-day residency requirement, and the only ground is irreconcilable differences.
- 02
Filing & service
A petition is filed with the circuit clerk in the proper county and formally delivered to the other spouse.
- 03
Disclosure & negotiation
Both sides exchange financial information and work toward agreements on property, support and parenting.
- 04
Resolution
Agreed terms are presented for approval, or unresolved issues are decided by the court after a hearing or trial.
Every case differs; timing depends on the court, the issues, and how much the spouses agree. Read the step-by-step filing guide.
