If both parents share custody does anyone pay child support?

Possibly. Support obligations are determined by calculating the disparity in parties’ incomes. If a child spends 40% or more overnights per year with a noncustodial parent, a rebuttable presumption exists that the noncustodial parent is entitled to a reduction in their child support obligation.

If the parties have equally shared custody there may not be a support order if their incomes are substantially the same. If one parent makes more money than the other, there will generally be an order for child support even if the parties equally share custody.
