Neb. Sup. Ct. R. 4-212
When a specific provision for joint physical custody is ordered and each party's parenting time exceeds 142 days per year, it is a rebuttable presumption that support shall be calculated using worksheet 3. When a specific provision for joint physical custody is ordered and one party's parenting time is 109 to 142 days per year, the use of worksheet 3 to calculate support is at the discretion of the court. If child support is determined under this paragraph, all reasonable and necessary direct expenditures made solely for the child(ren) such as clothing and extracurricular activities shall be allocated between the parents, but shall not exceed the proportion of the obligor's parental contributions (worksheet 1, line 6). For purposes of these guidelines, a "day" shall be generally defined as including an overnight period.
