Mediation in Illinois - Frequently Asked Questions
How much does divorce mediation cost in Illinois?
Our own estimate for mediation in Illinois is about $275 per session, and the calculator above multiplies it by a session count it works out from your answers. The cost is usually split between both parties. Court-connected mediation programs in Illinois are often available at reduced rates, and some counties subsidize the first session.
Is mediation required in Illinois?
On our record, no: Illinois does not require mediation as a prerequisite to filing. That is our own record rather than Illinois's own court rules. Courts often encourage it, and judges in many counties have discretion to order mediation on contested issues. Programs at the courthouse are often free or reduced-fee for low-income filers.
How long do mediation sessions last in Illinois?
We hold no figure for how long a mediation session runs in Illinois, and the per-session cost on this page is our own figure for one session, whatever its length. Ask any mediator or court program you are considering how long its sessions run and how it charges for time beyond that.
Do attorneys participate in Illinois mediation?
It depends on the format. Court-connected mediation in Illinois usually does not include attorneys at the table. Private mediation can be either attorney-assisted (each spouse brings counsel) or attorney-free. Even when attorneys are not present in the room, most mediating spouses have a consulting attorney review the proposed agreement before signing.
What if mediation does not resolve everything in Illinois?
Partial agreements still help. Illinois courts will accept a partial settlement and try only the remaining issues, which is faster and cheaper than litigating from scratch.

How we calculate this estimate
Mediation is priced by the session, so the estimate is sessions multiplied by rate. The session count starts from how many issues are genuinely in dispute, then adjusts for whether both spouses are willing participants, whether custody is on the table, and whether the court ordered mediation. The per-session rate is the one our data holds for your state. You see the total, your likely share if costs are split, and how that compares with a contested case in the same state.
What the estimate assumes for Illinois
- The per-session rate is our own estimate rather than a measured or published one. It came into our data at the original build, nobody has checked it against a mediator's rate card since, and across all fifty states it takes nine distinct values, every one a multiple of 25. The session count is ours too, and the entry below explains what it rests on.
- Rates are per session with a private mediator. Court-connected programs are often cheaper or free, and some states subsidize them.
- Costs are usually split between spouses unless the court orders otherwise or the two of you agree on something else.
- Attorney time spent preparing for and attending mediation is billed separately.
Where the estimate stops
Some cases settle in a single session and some never settle at all. The estimate reflects a typical path, not a promise that mediation resolves your case. A licensed family law attorney can tell you whether mediation is realistic given what is actually in dispute.
