Illinois Custody Mediation: How It Works, What It Costs, and When It's Required

When Mediation Is Required in Illinois

Under 750 ILCS 5/602.10(c), the court shall order mediation to assist parents in formulating, modifying, or implementing a parenting plan unless it determines that impediments to mediation exist. If parents fail to submit an agreed parenting plan within the 120-day period, the court must order mediation, subject to that impediment exception. This isn't optional — it's a statutory mandate.

The exception is when the court finds that "impediments to mediation" exist. That typically means cases involving documented domestic violence, severe substance abuse, or a cognitive impairment that prevents meaningful participation. An active Order of Protection may be relevant to that determination, but it does not by itself guarantee a waiver.

Even outside the mandatory trigger, courts routinely recommend mediation at any point in a custody dispute. Judges prefer that parents reach their own agreements, and mediation resolves a large percentage of cases that would otherwise go to trial.

How Cook County Mediation Works

Cook County operates mediation through Family Court Services, which provides free mediation sessions for parents in contested custody cases. The program is limited — typically two sessions — but it's a structured opportunity to work through disputes with a trained mediator at no cost.

Both parents attend separately first for intake interviews, then meet jointly with the mediator. The mediator doesn't make decisions or issue recommendations to the judge. Everything discussed is confidential and can't be used as evidence if the case proceeds to trial.

Cook County also houses the "Focus on Children" parenting education program, but that's a separate requirement — don't confuse the two. The parenting class is mandatory for covered parties subject to Rule 924's exceptions. Mediation is a separate court-referred process under Section 602.10(c), Rule 905, and local rules.

Mediation in Other Counties

Outside Cook County, mediation looks different. Most downstate and collar counties don't have free court-run mediation programs. Instead, the court orders parents to select a private mediator and split the cost.

Private family mediation in Illinois typically costs $100 to $500 per hour, with most sessions running two to four hours. Some mediators offer flat-rate packages for a full parenting-plan mediation (usually three to five sessions). Many mediators are family law attorneys who also practice mediation, and their rates reflect their legal expertise.

Counties with their own mediation programs include DuPage (through the Family Center) and Lake County, but the scope and availability vary. Check with your Circuit Clerk's office for local resources.

What Happens in a Mediation Session

Mediation isn't arbitration. The mediator has no authority to impose a decision. Their role is to facilitate a structured conversation, identify areas of agreement, and help parents work through the specific points they disagree on.

A typical custody mediation addresses:

• The parenting-time schedule — which days, transition times, pickup/dropoff logistics
• Decision-making allocation — who decides education, health, religion, extracurriculars
• Holiday and vacation rotations
• Right of first refusal terms
• Communication protocols between parents
• Relocation provisions

If you reach a full or partial agreement, the mediator drafts a memorandum of understanding. Your attorneys (if you have them) then convert that into the formal language required for the parenting plan. If mediation fails, the case goes back to the court for a contested hearing.

How to Prepare for Mediation

Parents who walk into mediation with a specific, written proposal resolve their disputes faster and at lower cost than parents who show up hoping to "talk things out." Before your session:

Know your schedule. Map out a week-by-week parenting-time proposal. Don't say "I want 50/50" — say "I want a 2-2-5-5 rotation with Monday/Tuesday with me, Wednesday/Thursday with you, and the five-day blocks alternating Friday-through-Tuesday and Wednesday-through-Sunday."

Know the financial stakes. Under the Income Shares Model, your parenting-time split drives child support. If you're asking for at least 146 overnights for the non-majority parent under current law (at least 110 for each parent starting January 1, 2027 under SB3524), that triggers the shared-care calculation. Understand what your proposal means financially before you negotiate.

Document your caretaking history. Courts and mediators respond to evidence. If you've been the parent doing school pickups, cooking dinner, and handling bedtime for the past two years, that history supports your request for substantial parenting time.

Prioritize. Decide in advance which provisions are essential and where you have flexibility. If the school district matters more to you than the holiday rotation, you'll negotiate more effectively by knowing your own priorities.
