N.D. Admin. Code 75-02-04.1-08.2
A child support obligation must be determined as described in this section in all cases in which a court orders each parent to have equal residential responsibility for their child or children. Equal residential responsibility means each parent has residential responsibility for the child or children for an equal amount of time as determined by the court. If equal residential responsibility is ordered for all the children, a child support obligation for each parent must be calculated under this chapter, and specifically ordered, assuming the other parent has primary residential responsibility for the child or children subject to the equal residential responsibility order. If equal residential responsibility is not ordered for all the children, a child support obligation must be calculated and specifically ordered for each parent for the children for whom the other parent has primary residential responsibility plus the children for whom the parents have equal residential responsibility. The lesser obligation is then subtracted from the greater. The difference is the child support amount owed by the parent with the greater obligation. Each parent is an obligee to the extent of the other parent's calculated obligation. Each parent is an obligor to the extent of that parent's calculated 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.
