Can One Parent Receive Sole Decision-Making Authority in Illinois?
When parents separate or divorce in Schaumburg, a key question is who will make major decisions for their children. Illinois law does not require parents to share this authority equally. A court can give one parent sole responsibility for certain important decisions if it is in the child’s best interests. This does not mean the other parent loses parenting time or becomes uninvolved. In Illinois, decision-making and parenting time are related but separate legal issues. I often tell parents that courts care less about terms like “sole custody” and more about whether the arrangement helps important decisions get made safely and in the child’s best interests.
Illinois Law Allows Sole Decision-Making Authority
Illinois law refers to what many parents still call “legal custody” as the allocation of significant decision-making responsibilities. Under 750 ILCS 5/602.5, a court must allocate those responsibilities according to the child’s best interests. The statute specifically states that Illinois law does not require each parent to receive decision-making authority.
A judge can give decision-making power to one or both parents. The court can also split authority by topic. For example, one parent might handle education decisions, while both share health care choices. In some cases, if parents cannot work together, one parent may get sole responsibility for all major areas to protect the child’s well-being.
This flexibility allows the court to create an arrangement based on the family’s actual circumstances rather than assuming every family should receive the same structure.
What Decisions Can One Parent Be Given Authority To Make?
Section 602.5 identifies several categories of significant decisions affecting a child. These include education, health care, religion, and extracurricular activities. Educational authority can involve choices about schools, tutoring, educational services, and other significant academic matters. Health-related authority may include medical, dental, psychological, and treatment decisions.
The court can allocate each category individually. This means a parent asking for sole decision-making authority should identify which decisions are actually creating problems and why shared authority is not working or would not work. A disagreement about one category does not necessarily justify giving one parent complete authority over every important issue.
Routine decisions are treated differently. Under 750 ILCS 5/602.5(d), the parent exercising parenting time generally has authority to make routine decisions for the child during that time, along with emergency decisions involving the child’s health and safety. Therefore, even when one parent receives sole significant decision-making authority, the other parent ordinarily continues making parenting decisions while the child is with that parent.
How Does A Court Decide Whether Sole Authority Is Appropriate?
The central question under 750 ILCS 5/602.5 is the child’s best interests. A judge must consider all relevant circumstances rather than simply deciding which parent appears more persuasive or which parent first requested sole authority.
Among the statutory factors are the child’s adjustment to home, school, and community, the physical and mental health of those involved, the child’s needs, each parent’s prior participation in significant decisions, previous agreements between the parents, and the parents’ respective wishes. The court may also consider the child’s wishes when the child has sufficient maturity and ability to express a reasoned and independent preference.
One of the most significant factors is the parents’ ability to cooperate in making decisions. The statute specifically permits the court to consider the level of conflict between the parents and whether that conflict affects their ability to share responsibility. Constant disagreement alone does not guarantee sole authority, but a documented pattern showing that joint decision-making repeatedly prevents necessary decisions from being made can be highly relevant.
High Conflict Can Support Sole Decision-Making
Some parents assume joint decision-making must be ordered unless the other parent is abusive or dangerous. That is not the standard. Sole significant decision-making may be appropriate even when both parents are capable of caring for the child if they cannot effectively make important decisions together.
Think about parents who often get stuck on big issues like medical care, school, or therapy. If every major decision leads to long arguments or no action, sharing authority can make things unstable for the child. In these cases, a judge might give one parent the authority to make decisions to keep things consistent and avoid ongoing conflict.
However, ordinary disagreements are expected in parenting relationships. A parent asking for sole authority should be prepared to demonstrate why the conflict is serious enough to affect the child’s welfare or the parents’ ability to make timely decisions.
A Parent’s Past Involvement Can Matter
Illinois courts may consider how involved each parent has historically been in important decisions affecting the child. Under 750 ILCS 5/602.5, the court can examine the level of each parent’s participation in past significant decision-making and any prior course of conduct between the parents.
For example, if one parent has consistently handled medical appointments, communicated with teachers, arranged educational services, and coordinated activities while the other parent remained largely uninvolved, that history may become relevant. It does not automatically determine the outcome, but it can help the court understand how decisions have historically been made and which arrangement may provide greater continuity.
I advise parents not to exaggerate their involvement. School records, medical records, emails, text messages, scheduling applications, and testimony can often establish who actually participated in significant decisions.
Domestic Violence And Abuse Can Affect Decision-Making Authority
Allegations involving domestic violence, abuse, or threats require particularly careful consideration. Under 750 ILCS 5/602.5, the court may consider physical violence or threats of physical violence directed against the child, as well as abuse against the child or another member of the child’s household.
Illinois law also permits restrictions on parental responsibilities under 750 ILCS 5/603.10. If the court finds after a hearing that a parent’s conduct seriously endangered the child’s mental, moral, or physical health, or significantly impaired the child’s emotional development, the court may reduce or eliminate that parent’s decision-making responsibilities, adjust parenting time, require supervision, impose treatment requirements, or enter other protective conditions.
These cases are highly fact-specific. Allegations should be supported by credible evidence whenever possible, particularly when one parent is asking the court to substantially restrict the other’s parental rights.
Sole Decision-Making Does Not Mean Sole Parenting Time
This distinction is one of the most important points for parents to understand. Significant decision-making authority is governed primarily by 750 ILCS 5/602.5, while parenting time is addressed separately under 750 ILCS 5/602.7.
A parent may therefore have sole authority over major decisions while the other parent still receives substantial parenting time. The court must independently determine parenting time according to the child’s best interests. Illinois law presumes parents are fit, and parenting time generally will not be restricted unless the statutory requirements for a restriction are satisfied.
A parent cannot assume that receiving sole decision-making authority means receiving every weekend, most overnights, or exclusive physical care of the child. Each issue requires its own legal analysis.
How Illinois Courts Determine Parenting Time
Under 750 ILCS 5/602.7, courts consider numerous factors when determining parenting time. These include the child’s needs and wishes when appropriate, each parent’s prior caretaking involvement, the child’s adjustment to home, school, and community, the distance between the parents’ homes, the parents’ schedules, and their ability to cooperate with the proposed arrangement.
The court also considers each parent’s willingness and ability to place the child’s needs ahead of personal interests and to encourage a close and continuing relationship between the child and the other parent. Violence, abuse, and circumstances that may justify restrictions are also relevant.
This means a parent who receives sole decision-making authority should still avoid interfering unnecessarily with the other parent’s relationship with the child. Decision-making authority is intended to serve the child, not to provide leverage against the other parent.
Can Decision-Making Be Divided Between Parents?
Yes. Illinois law allows courts to allocate different categories to different parents. This can sometimes provide a practical solution when parents communicate poorly but have different strengths or areas of historical involvement.
For example, one parent may receive authority concerning education while the other receives authority concerning medical care. The parents might share another category. The appropriate arrangement depends on the child’s needs and the evidence presented.
Dividing authority can reduce conflict in some cases, but it can create additional problems if the categories overlap significantly. Medical issues can affect school attendance, educational decisions can influence extracurricular activities, and psychological treatment can involve both educational and medical considerations. For that reason, an allocation order should be drafted carefully and clearly.
Can Sole Decision-Making Authority Be Changed Later?
An allocation of parental responsibilities does not necessarily remain unchanged until the child becomes an adult. Illinois law permits modification under certain circumstances, although the applicable legal standard can depend on when the requested change is made and what has occurred since the prior order.
A parent seeking a future modification should be prepared to show why circumstances justify changing the existing arrangement and why the proposed change serves the child’s best interests. Evidence that the current arrangement has become unworkable, that circumstances have materially changed, or that the child’s needs have changed may become important.
Likewise, a parent who initially did not receive significant decision-making responsibility may later seek greater involvement if circumstances support modification. These cases require close attention to the existing order, the history after its entry, and the current needs of the child.
Evidence Can Be Critical In A Sole Decision-Making Dispute
Requests for sole authority often turn on specific evidence rather than broad accusations that the other parent is “difficult.” Courts generally need facts demonstrating how the conflict affects actual parenting decisions.
Useful evidence may include communications showing repeated refusal to discuss important issues, school or medical records, documentation of missed appointments, evidence of unilateral decisions, testimony from relevant witnesses, or records establishing a parent’s history of involvement. When safety concerns exist, police reports, protective orders, treatment records, or other admissible evidence may also become relevant.
I encourage parents to focus on the child’s needs and specific decision-making problems rather than compiling every disagreement that occurred during the relationship. Illinois law directs courts not to consider parental conduct that does not affect the parent’s relationship with the child. A strong case therefore concentrates on legally relevant facts.
Protecting Your Rights In An Illinois Decision-Making Dispute
Disputes over significant decision-making authority can affect a child’s education, medical care, psychological treatment, activities, and overall stability for years. Whether you are requesting sole authority or opposing a request by the other parent, the court will focus on the child’s best interests and the evidence concerning how decisions have actually been made.
I represent parents on either side of these disputes and evaluate the complete history of parental involvement, communication, decision-making, parenting time, safety concerns, and the child’s needs. A carefully prepared case should explain not merely what arrangement a parent wants, but why that arrangement is workable and consistent with Illinois law.
