Allocation of Parental Responsibilities in Illinois: Why 'Custody' is Obsolete

Introduction to the 2016 IMDMA Changes

In 2016, the Illinois Marriage and Dissolution of Marriage Act (750 ILCS § 5/101 et seq.) underwent a massive overhaul. The traditional concept of "custody" was completely removed from the legal dictionary in Illinois. Instead, the law now focuses on the 750 ILCS § 5/602.5 allocation of parental responsibilities. This change was designed to reduce conflict between parents and focus on the child's best interests. Rather than fighting over who gets "sole custody," parents now divide decision-making powers across four critical areas: education, healthcare, religion, and extracurricular activities. If you are navigating this process in Chicago, Joliet, or Waukegan, understanding these new terms is the first step toward protecting your parental rights.

Step-by-Step Process for Allocating Parental Responsibilities in Illinois

Whether you live in Cook County, DuPage County, or Sangamon County, establishing parental responsibilities generally follows a specific path through the Illinois Circuit Court system. You must ensure you follow local rules, as a judge in the 18th Judicial Circuit Court of DuPage County, Wheaton might have slightly different scheduling procedures than one in Peoria.

Step 1: Gathering Documents and Filing the Petition

The first step is to file a formal request with the court. If you are married, this is typically done alongside your divorce papers. If you are unmarried, you will file a Petition to Establish Allocation of Parental Responsibilities. You will file these forms at your local Circuit Court, such as the Circuit Court of Cook County, Chicago or 19th Judicial Circuit Court of Lake County, Waukegan. You may need to use the Form APR, Illinois, Illinois Supreme Court Commission on Access to Justice, Petition for Allocation of Parental Responsibilities.

Step 2: Drafting the Parenting Plan

Under 750 ILCS § 5/602.10, all parents must submit a proposed Parenting Plan within 120 days of filing. This document outlines how you will split decision-making and parenting time. The state provides a standard Form ATJ 108.4, Illinois, Illinois Supreme Court Commission on Access to Justice, Parenting Plan (Divorce with Children) that covers all mandatory fields, including the child's primary residence for school purposes and a detailed schedule for holidays and summer vacations.

Step 3: Mandatory Mediation

If you and the other parent cannot agree on the Parenting Plan, Illinois law requires you to attend mediation. Mediators are neutral third parties who help you resolve disputes regarding education, health, religion, or extracurriculars. If mediation fails, the court will step in to make a determination. You might also interact with a Guardian ad Litem if the court appoints one.

Step 4: Court Hearing and Final Order

If disputes remain, a judge will make the final allocation based on the "best interests of the child" standard. The judge will issue an Allocation Judgment, which becomes a legally binding court order.

Sole vs. Joint Decision-Making

In Illinois, decision-making is broken down into four major categories. Parents can share joint responsibility for all four, or they can divide them. For instance, one parent might have sole authority over healthcare decisions, while both parents jointly decide on education and religion. The courts evaluate parental cooperation under 750 ILCS § 5/602.5; when high levels of parental animosity make cooperation impossible, courts will not force equal parenting time or joint decision-making against the child's best interests, as demonstrated in In re Marriage of Virgin, 2021 IL App (3d) 190650 (IL Appellate Court 2021).

How Illinois Mediators Assign Disputed Areas

When parents cannot agree, mediators look closely at the historical involvement of each parent. If one parent has always taken the child to doctor appointments in Naperville, coordinated official immunization records through the Illinois Department of Public Health, Springfield, or communicated directly with the child's pediatrician or local pediatric clinic, the mediator will likely suggest that this parent retain healthcare decision-making. The goal is to maintain stability and consistency for the child's daily life.

The Impact of Allocation on School District Registration

Even though "custody" is obsolete, school districts still need to know where the child lives. The Parenting Plan must designate one parent's address as the child's residence for school enrollment purposes. This does not give that parent more "power," but it dictates whether your child attends school in the Chicago Public Schools system or a suburban district. It is highly recommended to finalize this detail before the school year begins.

How Much Does it Cost in Illinois?

The costs can vary significantly based on whether your case is contested or uncontested. Here is a general breakdown of what you might expect to pay in Illinois:

How Long Does the Process Take?

An uncontested allocation where both parents agree on the Parenting Plan can be finalized in 2 to 3 months. However, if the case is heavily disputed and requires a trial, psychological evaluations, or a Guardian ad Litem, the process can drag on for 12 to 18 months in the Illinois Circuit Court system.
