• Low-Income Provision: When obligor's income falls in the shaded area of the schedule, a second calculation using only the obligor's income is performed; the lesser amount applies.
• Modification: Requires a significant variance of 15% or more (7.5% for orders initially set under Income Shares).
• Income Imputation: If a parent fails to provide income evidence, median income figures may be imputed.
• Parenting Plan Required: All custody orders require a parenting plan specifying days with each parent.
