Extracurricular activities — sports teams, music lessons, tutoring, summer camps, dance classes — are one of the most common financial flashpoints between co-parents. The costs add up fast, and disagreements usually boil down to two questions: who gets to decide which activities the child does, and who pays for them.
Both of these questions should be answered by your custody agreement. But the way they're answered varies enormously from one agreement to the next.
Decision-Making: Who Chooses the Activities?
Whether a parent can unilaterally enroll a child in an activity depends on your agreement's decision-making provisions. If you have joint legal custody, extracurricular activities may require mutual agreement — meaning neither parent can sign the child up for a new activity without the other's consent.
However, some agreements treat extracurriculars as a "routine" decision rather than a "major" one, which means the parent who has the child at the time can make the call. Others explicitly list "extracurricular activities" as a category requiring joint decision-making. The distinction matters: if your agreement requires mutual agreement and your co-parent enrolled your child without consulting you, they've arguably violated the agreement.
Who Pays: Common Arrangements
Custody agreements handle extracurricular costs in several ways. The most common are a percentage split — costs are divided in proportion to each parent's income (60/40, 70/30, etc.), often mirroring the child support calculation; a 50/50 split — regardless of income, each parent pays half; mutual agreement required — costs are shared only for activities both parents agree to in advance (if one parent enrolls the child without the other's agreement, that parent bears the full cost); and the enrolling parent pays — whichever parent signs the child up is responsible for the cost.
Some agreements combine these: shared costs for agreed-upon activities, sole responsibility for unilateral enrollments. This is actually the fairest approach — it encourages communication while preventing one parent from creating financial obligations for the other without consent.
What Counts as an "Extracurricular"?
This is where it gets gray. Organized sports, music lessons, and summer camp are clearly extracurricular. But what about tutoring? Is that academic support (which might fall under "education" in your decision-making clause) or an extracurricular expense? What about a school-required field trip? What about club dues or equipment?
The answer depends on your agreement's definitions. Some agreements define "extracurricular activities" broadly to include "any organized activity outside of regular school hours." Others are narrower. If your agreement doesn't define the term, you may need to negotiate with your co-parent or seek clarification through mediation.
What does YOUR agreement say about activities and expenses?

Check Your Agreement — FreeWhat to Do When Your Ex Signs Up Without Asking
If your co-parent enrolled your child in an activity without consulting you — and your agreement requires mutual agreement — start by checking the specific language. Then communicate in writing: "I see that [child] has been enrolled in [activity]. Our agreement requires that we agree on extracurricular activities together (Section X.X). I'd like to discuss this before committing to the cost and schedule impact."
Don't refuse to let your child participate as leverage — that hurts the child, and a judge won't look favorably on it. Instead, address the process violation directly with your co-parent and, if necessary, raise it in mediation. If it's a pattern, document each instance. A parent who repeatedly makes unilateral decisions despite a joint decision-making clause is violating the court order.
Keeping It About the Kids
Extracurricular disputes are often less about the money than about control. Both parents want a voice in their child's development. The best approach is to treat activity decisions as a joint conversation — even if your agreement technically gives you the unilateral right to decide. A quick text saying "I was thinking about signing Ella up for swim lessons on Wednesdays — what do you think?" costs nothing and prevents a lot of resentment.
When money is genuinely tight, be transparent about what you can and can't afford. Courts and mediators are sympathetic to genuine financial constraints — they're much less sympathetic to a parent who can afford the activity but refuses to pay on principle.
