Avoid These Three Simple Mistakes in Your Illinois Custody Dispute

 Posted on October 14, 2026 in Child Custody

Parents frequently disagree about issues related to the allocation of parental responsibilities and parenting time during their divorce. When parents cannot reach an agreement or create a parenting plan, mediators or a collaborative divorce team may be able to help. However, if other methods fail or if a case is extremely contentious, parents may end up litigating their custody dispute in an Illinois family law court.

At A. Traub & Associates, our Wheaton, IL family law attorneys bring over 100 years of combined experience to the table. We know how meaningful the allocation of parenting time and decision-making responsibilities can be, so we provide personalized service suited to your unique situation.

What Three Mistakes Should Parents Avoid in 2026 Custody Disputes?

Although there is no failsafe way for a parent to ensure they get what they want in a court hearing, there are certain mistakes that parents should try to avoid:

Sharing Details of the Dispute on Social Media

Nearly everyone uses social media, but during a contentious divorce, putting too many details on social media accounts can have negative consequences. Even with the most private account settings, information can be obtained and used as evidence in court. Trash-talking the other parent, posting pictures of late-night parties, and even photos of fun but risky behaviors with children may be used to try to prove lack of parental fitness in court. When in doubt, less is more when it comes to social media use.

Trying to Get Revenge on an Ex

Parents using court disputes to hash out resentments over their relationship issues is highly frowned upon in the court. Although spouses may have very good reasons for disliking each other once a divorce has begun, allowing that bitterness to influence negotiations over the children will get in the way of discovering and pursuing the children’s best interests.

Judges have seen many parents arguing over their children, and can tell when one spouse is trying to get back at the other. Save frustrations with a spouse for a therapist and use the court to find a good solution for the children.

Exposing Children to Parental Conflict

Children suffer when parents use them as weapons in their conflict. Children should be kept out of personal and legal conflicts and should never be a listening ear for parental grievances. Parents should also never try to alienate each other from their children, criticize each other to the children, or use the children as messengers when they cannot communicate effectively. If a judge discovers parents engaging in these behaviors, it could negatively influence court proceedings.

What Is the Deciding Factor in the Allocation of Parental Responsibilities?

In Illinois, the deciding factor in the allocation of parental responsibilities is the best interests of the child. Illinois law uses the term "allocation of parental responsibilities" in place of "custody." Under this approach, a judge divides two things between parents. The first is decision-making, which covers major choices about school, medical care, and religion. The second is parenting time, which is the schedule for when the child stays with each parent. To decide how to divide parenting time, the judge reviews a set of factors found in state law (750 ILCS 5/602.7). These factors include, but are not limited to:

• The wishes of each parent and of the child
• How involved each parent has been in daily care
• The child’s adjustment to home, school, and community
• The mental and physical health of everyone involved
• Any history of abuse or violence
• Each parent’s willingness to support the child’s bond with the other parent

No single factor takes precedence over all others. A parent who earns more money does not automatically get more time. A parent who stayed home with the child does not automatically win either. The court wants a plan that keeps the child safe, stable, and connected to both parents when possible.

What Is a Guardian ad Litem, and How Are They Used in Custody Disputes?

A guardian ad litem is an attorney the judge appoints to look into a custody case on the child’s behalf. Judges often appoint one when parents strongly disagree or when there are concerns about a child’s safety. The guardian ad litem does not work for either parent. Rather, his or her job is to learn what arrangement would serve the child best.

To do this, the guardian ad litem may visit each parent’s home and talk with the child. He or she may also speak with teachers, doctors, and others in the child’s life. Afterward, the guardian ad litem gives the judge a report with a recommendation. The guardian ad litem can also testify in court, and both parents may question him or her.

The judge does not have to follow the recommendation, but it often carries a lot of weight. Parents should treat every meeting with the guardian ad litem seriously. Being honest, on time, and focused on the child can help. Parents may also be ordered to share the cost of the guardian ad litem’s fees.

How Should Parents Prepare for a Contested Custody Hearings?

Parents preparing for a contested custody hearing in Illinois should start gathering proof well before the court date. A judge makes decisions based on evidence, not on who tells the better story. Helpful records can include report cards, medical records, and calendars showing who handled school pickups and appointments. Texts and emails with the other parent can also show how each parent communicates.

Parents should also be ready with a clear parenting plan. Illinois requires parents to file a proposed parenting plan with the court, either on their own or together. A strong plan covers school routines, holidays, travel between homes, and how parents will share news about the child.

Witnesses can help as well. A teacher, coach, or family friend may be able to describe a parent’s role in the child’s life. Parents can talk with an attorney about which witnesses would be most useful.
