Determination of child support obligation - Split custody or primary residential responsibility

A child support obligation must be determined and specifically ordered for the child or children for whom each parent has primary residential responsibility pursuant to a court order or, if there is no court order, for whom each parent has primary physical custody. The lesser obligation is then subtracted from the greater. The difference is the child support amount owed by the parent with the greater obligation. The offset of child support obligations in this section is for payment purposes only and must be discontinued for any month in which the rights to support of a child for whom the obligation was determined are assigned to a government agency as a condition of receiving public assistance.
