Subject to the provisions of RSA 458-C:5, guidelines provided under this chapter shall be applied in all child support cases, including temporary orders, and in any order modifying a support order.II.

A written finding or a specific finding by the presiding officer on the record that the application of the guidelines would be unjust or inappropriate in a particular case, as determined by using the criteria set forth in RSA 458-C:5, shall be sufficient to rebut the presumption in such case.III. [Repealed.]IV.
