WashingtonAlimony & Child Support

Washington uses a discretionary test — there's no bright-line statutory threshold. A judge or clerk evaluates the factors below and rules based on the full financial and situational picture. The calculator cannot compute a specific answer here, but these are the factors a court will weigh.

What the court will weigh

Gather documentation for the factors that apply to your situation — judges grant waivers more readily when the affidavit is specific.

  1. Financial resources of party seeking maintenance

    RCW 26.09.090(1)(a): the financial resources of the party seeking maintenance, including separate or community property apportioned to him or her, and his or her ability to meet his or her needs independently, including the extent to which a provision for support of a child living with the party includes a sum for that party as custodian.

  2. Time needed to acquire education or training for employment

    RCW 26.09.090(1)(b): the time necessary to acquire sufficient education or training to enable the party seeking maintenance to find employment appropriate to his or her skill, interests, style of life, and other attendant circumstances.

  3. Standard of living during the marriage

    RCW 26.09.090(1)(c): the standard of living established during the marriage or domestic partnership.

  4. Duration of marriage or domestic partnership

Washington Child Support Calculation Under RCW 26.19.020

In Washington, spousal maintenance and child support are governed by separate statutes, with no single formula linking them. Child support is calculated under the standard schedule in RCW 26.19.020, which uses the parents' combined monthly net income and the number of children. A worksheet, as prescribed by RCW 26.19.071, applies a basic support obligation, which may be adjusted for each parent's residential time and other items. Deviations from the schedule are permitted under RCW 26.19.075, based on factors set out in the statute. Spousal maintenance, governed by RCW 26.09.090, is determined by the court considering factors listed in that law and is not automatically tied to the child support amount. A verified figure of $72,000 appears in the official source. The example below demonstrates how the child support calculation proceeds using the schedule. To estimate a potential obligation, use the DocketMath calculator.
