Decision-Making Authority
Decision-Making Authority
in Illinois
As an Illinois decision-making authority attorney, I see this question come up regularly: who makes the final call on your child's schooling, medical care, religious upbringing, and activities.
The authority most parents don't think about until they need it.
When most people think about child custody, they think about the schedule — where the children sleep, who has them on holidays. What they often overlook is decision-making authority: the legal right to make major choices about a child's education, healthcare, religion, and activities.
Illinois law since 2016 requires courts to allocate this authority explicitly as part of every parenting order. It can be allocated jointly — requiring both parents to agree — or solely to one parent. It can even be split by category, with one parent holding authority over educational decisions and both parents sharing healthcare decisions. The arrangement that looked fine at the time of the divorce often becomes a source of serious conflict years later — when a parent wants to change schools, when parents disagree about medical treatment, or when one parent consistently makes decisions without consulting the other.
We help parents establish clear, enforceable decision-making arrangements from the outset — and we help parents whose co-parent isn't respecting those arrangements enforce them.
The allocation of significant decision-making responsibilities is governed by 750 ILCS 5/602.5. Courts must allocate decision-making across four specific categories — education, healthcare, religion, and extracurricular activities — based on the best interest of the child and the ability of the parents to cooperate. The allocation can differ by category, giving courts and families significant flexibility in structuring arrangements that reflect the actual co-parenting dynamic.
The Four Categories
What decision-making authority
actually covers.
Illinois law identifies four specific categories of significant decision-making responsibility. Each category can be allocated independently — which means a parent can have sole authority in one area and share authority in another. Understanding what falls within each category is the starting point for any decision-making dispute.
Education
What this category covers
Educational decision-making authority covers the selection of schools — public, private, charter, or homeschool — as well as major decisions about a child's educational placement, IEP or 504 plan participation, grade retention, tutoring programs, and similar significant academic decisions.
It does not cover day-to-day homework supervision or routine school-related logistics during a parent's parenting time. Those decisions belong to the parent who has the child.
Where disputes arise
Educational disputes are among the most common post-decree conflicts. One parent wants to change schools — perhaps to a private school, a school in a different district, or a school closer to their home. One parent wants to pursue testing for learning differences; the other resists. A child is struggling and the parents disagree on whether intervention is needed.
School transfers · Private vs. public school · IEP decisions · Grade retention · Extracurricular educational programs
Healthcare
What this category covers
Healthcare decision-making authority covers the selection of primary care physicians, specialists, therapists, and dentists — as well as significant treatment decisions including elective procedures, medication for chronic conditions, mental health treatment, and similar major medical choices.
Emergency medical care is always permitted by the parent who has the child, regardless of how decision-making authority is allocated. Healthcare decision-making authority is about non-emergency major decisions, not routine care during parenting time.
Where disputes arise
Healthcare disputes frequently involve disagreements about whether a child should begin medication (particularly for ADHD or mental health conditions), which physician or therapist to use, whether a particular treatment is necessary, and whether a child needs mental health intervention at all.
ADHD / mental health medication · Therapist selection · Elective procedures · Vaccination decisions · Specialist referrals
Religion
What this category covers
Religious decision-making authority covers the child's formal religious upbringing — participation in religious education, confirmation or bar/bat mitzvah preparation, religious school enrollment, and similar significant religious practices and commitments.
Each parent generally retains the right to engage in religious activities with the child during their own parenting time, including attending religious services. Religious decision-making authority primarily governs formal religious commitments that affect both parents' time with the child.
Where disputes arise
Religious disputes often arise when parents have different faith backgrounds or when one parent has changed or abandoned their religious practice after the divorce. They can also arise when one parent seeks to enroll a child in religious education or commit the child to a religious milestone that requires significant time and preparation.
Confirmation / bar mitzvah preparation · Religious school enrollment · Conversion · Holiday observance · Exposure to different faiths
Extracurricular Activities
What this category covers
Extracurricular decision-making authority covers the enrollment and participation in organized activities outside of school — sports teams, dance or music programs, clubs, scouting, and similar commitments that impose schedules and obligations on both parents' parenting time.
A parent cannot unilaterally commit a child to an activity that significantly intrudes on the other parent's parenting time without that parent's agreement — unless the allocation order grants one parent sole authority over extracurricular decisions.
Where disputes arise
Extracurricular disputes often arise when one parent wants to enroll a child in a competitive travel sports team that requires weekend commitments during the other parent's parenting time. They also arise when parents disagree about the intensity of a child's activity schedule, or when one parent refuses to facilitate a child's participation in an activity the child loves.
Travel sports teams · Competition schedules conflicting with parenting time · Activity overcommitment · Withdrawal from established activities
When Co-Parents Conflict
What happens when joint decision-makers can't agree.
Joint allocation works well when both parents can communicate civilly. When they can't — or when one parent consistently makes unilateral decisions despite a joint allocation order — there are specific legal mechanisms available to resolve the dispute and address the violation.
The options when agreement breaks down
A well-drafted allocation order anticipates disagreement and includes a dispute-resolution mechanism. When no mechanism exists — or when it's been exhausted — there are formal paths available.
What this category covers
Many allocation orders include a mediation requirement before either party can return to court on a decision-making dispute. A mediator helps the parents work toward agreement on the specific decision at issue — education placement, medical treatment, or other conflict. Mediation is faster and less expensive than court intervention and is often required as a first step.
Emergency Motion
When a decision can't wait — a medical procedure, an urgent school placement, a time-sensitive issue — a parent can file an emergency motion asking the court to resolve the specific decision. Courts can intervene quickly when the situation warrants it, though emergency motions are not for routine disagreements.
Contempt of Court
When one parent consistently makes major decisions unilaterally in violation of a joint allocation order — enrolling a child in a new school without agreement, changing a primary care physician without notice — that parent is in violation of a court order. A contempt petition can result in makeup provisions, attorney fee awards, and in patterns of repeated violation, modification of the allocation itself.
Modification to Sole Allocation
When joint allocation repeatedly breaks down — when every major decision becomes a legal battle — Illinois courts can modify the arrangement to give one parent sole authority over specific categories or over all decision-making. This requires a showing of substantial change in circumstances and a finding that the modification serves the child's best interest.

These are the questions prospective clients most often raise before their first consultation. We've answered them honestly — because informed clients make better decisions, and that's better for everyone.
Can decision-making authority be allocated differently for each category?
What counts as a "major decision" vs. a day-to-day decision?
What if my co-parent makes a major decision without telling me?
Can my child's preference affect the decision-making allocation?
Does the parent with more parenting time automatically get more decision-making authority?
What happens if we can never agree on anything — can the court just give one parent all the authority?
