Child Support

Child support is the ongoing obligation of one parent to provide financial support of the children to the other parent. Oregon expects both parents to financially support their children, and this obligation exists whether the parties were married and then divorced, were never married, or even if they never lived together before their child was born.

Child support is calculated by a federal mandated formula, and each state is required to adopt it. Oregon’s child support formula has been established by the Oregon Department of Justice, through its Child Support Program. The main variables that affect child support in Oregon are:

  • Each parent’s gross monthly income.

  • Health insurance costs for both parents, as well as for the child or children.

  • Work-related childcare costs, if any.

  • The number of overnights each parent has with the child per year.

  • Whether either parent has children from any prior relationship.

To learn more about how Oregon calculates child support, you can access Oregon’s Child Support Guidelines and Child Support Calculator here.

If both parents agree, then it is possible for one parent to pay the other parent either more or less than the amount determined by the calculator. Sometimes the court itself will order one parent to pay more or less than the guidelines calculation. Such adjustments always depend upon the facts in your specific case.

Under Oregon law, a child support obligation typically ends when the child turns 18, unless the child is continuing their education at least half-time. Then child support may be extended until that child turns 21.
