No. What each parent owes for a particular expense depends on what the court order says, not on how the expense is characterized. Base child support already covers a child’s ordinary day-to-day needs, so those are not separately billed between parents. Medical and dental support are handled separately because Texas law requires every support order to address them. Beyond those, decrees vary widely: an order may separately address extracurricular activities, school expenses, childcare, tutoring, camps, or other costs — or it may say nothing about them at all.
A single activity often involves several different costs: registration, uniforms, equipment, tournament fees, travel, and transportation. An order may allocate some of these without addressing the rest, and that distinction has real consequences. Where the order allocates a cost, it can be enforced according to its terms. Where the order is silent, the other parent generally has no obligation to contribute, and a court cannot enforce an obligation the order does not impose. The parent who incurs an unaddressed cost usually ends up bearing it alone, unless the other parent agreed in advance to share it. That makes advance agreement worth getting in writing before a significant cost is incurred.
If the order does require reimbursement, follow its procedures carefully. Those provisions may require receipts or proof of payment, set each parent’s percentage, or impose a deadline for requesting reimbursement — and a parent who misses a deadline or cannot document the expense may lose the right to be reimbursed for it.
