When parents go through a contested divorce in Chicago or surrounding communities such as Skokie, Evanston, and Oak Park, one of the most critical legal issues involves determining parenting time and parental responsibilities. Illinois courts do not automatically favor one parent over the other. Instead, judges rely on a legal framework known as the “best interests of the child” standard.
.
This standard governs all decisions involving children under the Illinois Marriage and Dissolution of Marriage Act. Whether the dispute involves parenting time, decision-making authority, or modifications to an existing order, courts in Cook County focus exclusively on what arrangement will best support the child’s overall well-being.
.
Understanding how this standard is applied can help parents navigate contested divorce proceedings and protect their relationship with their child.

What “Best Interests of the Child” Means Under Illinois Law

The best interests standard requires courts to evaluate all relevant factors affecting a child’s physical, emotional, and developmental needs. Rather than applying rigid rules, Illinois law gives judges broad discretion to assess each family’s unique circumstances.
.
Under Illinois statutes, parenting time and decision-making responsibilities must be allocated in accordance with the child’s best interests, not the preferences or convenience of either parent.
.
This approach reflects a modern shift away from outdated assumptions—such as automatically favoring one parent—and toward a more balanced, child-centered analysis.

Key Factors Courts Consider in Contested Divorce Cases

When parents cannot agree on a parenting plan, the court will evaluate a detailed set of statutory factors. These factors are outlined in Illinois law and guide judges in determining appropriate parenting arrangements.

The Wishes of the Parents and the Child

Courts consider each parent’s proposed parenting arrangement as well as the child’s preferences, if the child is mature enough to express a reasoned opinion. However, a child’s wishes are only one factor among many and are not determinative.

Caretaking History and Parental Involvement

Judges closely examine the role each parent has played in the child’s life, particularly in the two years leading up to the divorce. This includes daily caregiving responsibilities such as feeding, education, medical care, and extracurricular involvement.

The Child’s Relationship With Each Parent

The strength and quality of the child’s relationship with each parent—and with siblings or other significant individuals—are critical considerations. Courts aim to preserve meaningful relationships whenever possible.

Adjustment to Home, School, and Community

Stability is a major factor. Judges evaluate how well the child is adjusted to their current living environment, school, and community. Disrupting a stable situation may be avoided unless there is a compelling reason.

Mental and Physical Health of All Parties

The physical and psychological well-being of both parents and the child are carefully reviewed. Any condition that affects a parent’s ability to care for the child may influence the court’s decision.

Ability to Cooperate and Co-Parent

Courts strongly favor parents who demonstrate a willingness to cooperate and facilitate a positive relationship between the child and the other parent. A lack of cooperation can negatively impact parenting time allocations.

Distance Between Parents’ Homes

In metropolitan areas like Chicago and nearby suburbs such as Skokie or Naperville, logistics matter. Courts consider travel time, school schedules, and the practicality of shared parenting arrangements.

History of Abuse or Violence

Any evidence of domestic violence, neglect, or abuse is taken very seriously. Courts prioritize the child’s safety and may restrict or supervise parenting time when necessary.

Any Other Relevant Factors

Illinois law allows courts to consider any additional factors that may impact the child’s best interests, giving judges flexibility to address complex or unique situations.

Parenting Time and Decision-Making Responsibilities

Illinois law separates what was traditionally called “custody” into two distinct components: parenting time and parental decision-making.
.
Parenting time refers to the schedule of when a child spends time with each parent. Decision-making responsibilities involve major life decisions related to education, healthcare, religion, and extracurricular activities.
.
Courts may allocate these responsibilities jointly or assign them primarily to one parent, depending on what best serves the child’s needs.

How Contested Divorce Impacts Parenting Decisions

In uncontested divorces, parents typically agree on a parenting plan. In contested cases, however, disagreements can escalate into formal litigation, requiring judicial intervention.
.
Contested divorce cases in Cook County courts often involve disputes over:

  • Allocation of parenting time
  • School placement and educational decisions
  • Religious upbringing
  • Healthcare decisions
  • Relocation requests

When parents cannot reach an agreement, the court may order mediation or appoint a guardian ad litem to investigate and make recommendations.

The Role of a Guardian ad Litem in Chicago Divorce Cases

In highly contested cases, the court may appoint a guardian ad litem (GAL) or child representative. This individual acts as an independent advocate for the child’s best interests.
.
The GAL may conduct interviews with parents, children, teachers, and other relevant parties. They may also review medical records, school reports, and other documentation before making a recommendation to the court.
.
While the GAL’s recommendation is not binding, it often carries significant weight in judicial decisions.

Shared Parenting and Modern Trends in Illinois

Illinois courts increasingly recognize the importance of both parents being actively involved in a child’s life. While equal parenting time is not guaranteed, courts often encourage arrangements that allow meaningful participation from both parents.
.
Research and legal trends suggest that children benefit when both parents remain engaged in their upbringing, provided that the environment is safe and supportive.
.
However, equal parenting time is not appropriate in every case. Courts must balance involvement with practical considerations and the child’s specific needs.

When Parenting Time May Be Restricted

Although Illinois law favors ongoing parental involvement, there are situations where parenting time may be limited.

Restrictions may be imposed when there is evidence of:

  • Domestic violence or abuse
  • Substance abuse issues
  • Neglect or unsafe living conditions
  • Behavior that endangers the child

In such cases, the court may order supervised visitation or impose conditions to protect the child’s safety.

Modifying Parenting Orders After Divorce

Parenting arrangements are not necessarily permanent. Illinois law allows modifications when there has been a substantial change in circumstances or when the existing arrangement no longer serves the child’s best interests.
.
Examples include:

  • A parent relocating within or outside the Chicago area
  • Changes in a child’s educational or medical needs
  • Concerns about a parent’s behavior or living situation

Courts generally prioritize stability, but they will intervene when necessary to protect the child.

Why Local Experience Matters in Chicago and Cook County

Family law cases in Chicago and surrounding areas such as Skokie and Evanston are handled within the Cook County court system, which has its own procedures and expectations.
.
Working with an attorney familiar with local judges, court rules, and regional dynamics can provide a strategic advantage. Local attorneys understand how courts in the area interpret best interest factors and can tailor arguments accordingly.
