How Child Support Works in Oregon
Oregon uses the Income Shares to determine child support obligations.
The Income Shares model combines both parents' incomes, finds the basic support obligation from a state schedule, then divides it proportionally. More parenting time (overnights) reduces the non-custodial parent's payment through a parenting time credit.
