All income and resources of the parties before the court, new spouses, and other adults in the household shall be disclosed and considered as provided. The presumptive amount of support shall be determined according to the child support schedule. Unless specific reasons for deviation are set forth in the written findings of fact and are supported by the evidence, the court shall order each parent to pay the amount of support determined by using the standard calculation.
The court shall enter findings that specify reasons for any deviation or any denial of a party's request for any deviation from the standard calculation made by the court. The court shall not consider reasons for deviation until the court determines the standard calculation for each parent.
When reasons exist for deviation, the court shall exercise discretion in considering the extent to which the factors would affect the support obligation.
Agreement of the parties is not by itself adequate reason for any deviations from the standard calculations.
