Find your next step in the Illinois family law case process

Where should you begin in the Illinois family law case process?

Cook County's Domestic Relations Division handles divorce, parentage, parenting time, decision-making, support and related matters. The legal issue determines the papers and rules that apply. A case about an existing parenting order can require a different approach from a new divorce.

Start with the stages of divorce guide for divorce, parenting and custody information for decisions about children, or child support information for support questions. If terms in your papers are unfamiliar, use the family law glossary.

Identify the papers and instructions that control your next step

An initial petition starts a case. An answer responds to its allegations; a motion asks the judge to act in a case already underway. Keep the petition, summons, filed responses, notices and signed orders together so you can identify what has happened and what is scheduled.

For divorce, the Illinois Courts instructions address filing, notifying the other spouse, arranging court dates and completing the case. Use the instructions for your situation, including the separate forms for cases with children. Do not assume that a general overview replaces the directions on the forms you are using.

How do you check your assigned court and hearing arrangements?

Cook County domestic relations cases are assigned to an individual calendar judge or a judicial team. Check your case record and hearing notice for the assigned calendar and current instructions.

A hearing may be in person or remote. The Illinois Courts divorce instructions explain how to confirm the arrangements and prepare the documents needed for court. Check the notice and the court's own instructions rather than relying on an old calendar link.

Separate parenting questions from financial questions

For children, parenting time and significant decision-making are distinct parts of parental responsibilities. A parenting plan addresses both. A proposed schedule does not, by itself, answer every question about education, health or other significant decisions.

Use the parenting information and support information as separate starting points. Bring the current order and a clear list of questions when you seek advice.

Understand what happens at the end of the case

The Illinois Courts divorce instructions distinguish cases with a complete agreement from cases where issues remain unresolved. An agreement still goes before the judge. Keep a copy of every order the court enters and read what it requires.

After a judgment, a new issue may concern compliance with the existing order or a requested change. The parenting modification page explains that topic. Read the current order before assuming a later agreement has changed it.

Choose legal help that matches the task

Illinois permits limited scope legal services such as advice, document review and representation for a defined part of a case. The limitation must be reasonable under the circumstances and the client must give informed consent (Ill. R. Prof'l Conduct 1.2(c)). Ask which tasks are included and who remains responsible for filing, service, deadlines and court appearances.

Before a consultation, write down the case number, court, next hearing date and the issue you want help with. Bring the documents that show the current status. If you do not know a detail, mark it unknown instead of guessing.
