Can My Child Choose Which Parent to Live With in Illinois?

 Posted on August 18, 2026 in Child Custody

Your child doesn't have an absolute legal right to choose which parent to live with in Illinois. However, a judge may consider a mature child's wishes as one factor among many when deciding custody and placement. If you're dealing with a custody dispute in 2026, our Wheaton, IL child custody lawyers can help you understand how your child's preferences might actually factor into your case.

What Does Illinois Law Say About a Child's Custody Preference?

Under 750 ILCS 5/602.5 and 750 ILCS 5/602.7, Illinois courts consider a child's wishes as one of several factors when determining parental responsibilities (the term for custody in Illinois) and parenting time (commonly known as visitation). This preference is never the deciding factor on its own, though. Judges weigh the child's stated preference alongside many other considerations. This includes each parent's relationship with the child and each parent's ability to provide a stable environment.

Even a strong preference expressed by a teenager doesn't guarantee the court will rule in favor of that preference. This is especially true if other factors suggest a different arrangement would better serve the child's overall well-being.

Is There a Specific Age When a Child's Wishes Matter More in Illinois?

Illinois law doesn't set a specific age at which a child's preference automatically matters. Instead, judges generally give more weight to the preferences of older, more mature children. These children need to articulate clear, well-reasoned explanations for their preference.

How Does a Judge Learn About a Child's Custody Preference?

Judges typically do not ask children to testify in open court about which parent they prefer. This could put a child in a difficult position. Instead, courts may use other ways to learn about a child's wishes.

One option is for the judge to interview the child privately in the judge's office. Under 750 ILCS 5/604.10, attorneys can be present unless the parties agree otherwise. A court reporter must also make a record of the interview.

The court may also appoint a guardian ad litem. This is an attorney who investigates the family's situation and makes recommendations about what would be best for the child.

What Role Does a Guardian ad Litem Play in Understanding a Child's Wishes?

A guardian ad litem investigates the family's situation. This often includes interviewing the child directly, along with both parents and other relevant witnesses. This person then makes a recommendation to the court that takes the child's expressed preferences into account. The recommendation also considers other important factors like each parent's home environment and involvement in the child's daily life.

What Other Factors Does an Illinois Court Consider Alongside a Child's Preference?

A child's preference is just one piece of a much larger picture the court considers when making custody and placement decisions. Common factors include:

• Each parent's ability to cooperate and make joint decisions
• The child's adjustment to their current home, school, and community
• Each parent's physical and mental health
• Any history of domestic violence or substance abuse
• The distance between each parent's home and how this affects the child's daily routine

So many factors are weighed together. Because of this, a child's preference alone rarely determines the outcome, especially when other factors point in a different direction.

Can a Child's Custody Preference Change Over Time?

A child's wishes can change as they get older. A new preference may be considered if a parent asks the court to change an existing parenting plan. However, a child's preference does not automatically mean that the court will make a change.

Under 750 ILCS 5/610.5, a court generally must find that circumstances have substantially changed before making a major change to a parenting plan. The court must also find that the change is in the child's best interests. However, Illinois law allows some changes without proof of substantially changed circumstances. A child's new preference may be one factor the court considers when deciding what is best for the child.

What Should You Do if Your Child Has Expressed a Strong Custody Preference?

If your child has shared a preference, protect their emotional health first. Don't pressure them to pick a side. Write down what they've said, in age-appropriate ways. Then talk to your attorney about it. Your attorney can present this information properly, so it's considered fairly as part of your case.
