Washington spousal maintenance amount

Washington courts decide maintenance amount and duration from statutory factors.

RCW 26.09.090 allows a Washington court to order spousal maintenance in an amount and for a period the court considers just after reviewing the relevant factors. The statute does not provide a statewide percentage formula. [1]

The Washington Courts family-law handbook likewise explains that courts have substantial discretion over how much maintenance is paid and for how long, and that maintenance does not use a formula like child support. [2]

Washington maintenance factors

Washington courts consider financial resources, training needs, marriage length, health, and ability to pay.

RCW 26.09.090 lists factors including the financial resources of the spouse seeking maintenance, the time needed for education or training, the standard of living during the marriage, the duration of the marriage, the requesting spouse’s age and physical and emotional condition, financial obligations, and the paying spouse’s ability to meet both sets of needs. [1]

The statute directs the court to make the maintenance decision without regard to misconduct. [1]
