How are variable expenses handled in Wisconsin child support cases?
Variable expenses are child-related expenses that fluctuate with a parent’s periods of physical placement and may be allocated separately from the basic child-support transfer payment in shared-placement cases. Wisconsin’s child-support rules identify categories of variable expenses and provide a framework for allocating them between parents.
Examples can include child care, tuition, special-needs expenses, and other costs that vary depending on the child’s activities or placement, depending on the governing order and the DCF 150 definition. The exact treatment should be stated clearly in the court order because disputes often arise when an order refers generally to “expenses” without identifying what is included, what documentation is required, and when reimbursement is due.
Parents may agree on a percentage allocation or the court may establish one. The allocation may reflect the child-support calculation, the parents’ incomes, and the circumstances of the case.
A good order should distinguish variable expenses from ordinary day-to-day expenses each parent is expected to cover during that parent’s placement time.
