A written finding for the establishment or modification of a child support order that the application of the child support schedule in § 25-7-6.2 would be unjust or inappropriate in a case is sufficient to rebut the presumption in that case. The best interest of the child must be taken into consideration. Findings to rebut application of the child support schedule must state the amount of support that would have been required under the schedule and include a justification of why the order deviates from the schedule.
