Application

The child support guideline schedule amount is rebuttably presumed to be the correct amount of child support in all child support determinations, including both temporary and permanent determinations, and including determinations necessitated by actions for the support of children of married persons, actions seeking domestic violence protection orders, actions arising out of divorce, actions arising out of paternity determinations, actions based upon a claim for necessaries, actions arising out of juvenile court proceedings, interstate actions for the support of children in which a court of this state has the authority to establish or modify a support order, and actions to modify orders for the support of children. The fact that two or more such actions may be consolidated for trial or otherwise joined for convenient consideration of facts does not prevent the application of this chapter to those actions.
