When combined monthly net income exceeds $5,000.00, support shall not be set at an amount lower than the presumptive amount of support set for combined monthly net incomes of $5,000.00 unless good cause is found to deviate below that amount, but the Tribal Court may exceed the presumptive amount of support set for combined monthly net income of $5,000 upon written findings of fact establishing such increase as both necessary and in the best interests of the child(ren). [Ord. 50 § 7.5(6), adopted, 3/23/2017.]
