Child Support in Washington
State-specific overview · Family Law
Washington calculates child support using combined parental income and a statutory schedule, with support typically ending at age 18.
How Washington treats Child Support
Washington's child support obligation follows RCW 26.19, which establishes a combined parental income model with a percentage-based schedule. The paying parent's share is determined by dividing their income by combined parental income, then applying the appropriate percentage from the state's published schedule. Child support generally terminates when the child reaches age 18, graduates from high school, or becomes self-supporting, whichever occurs first. The court may adjust support based on the child's special needs, educational expenses, or other relevant factors.
The general definition of Child Support
Court-ordered payments from one parent to the other for a child's living expenses.
Child support is money that a court requires one parent to pay to the other parent (or guardian) to help cover the child's expenses like food, housing, education, and healthcare. The amount is usually calculated using state guidelines that consider both parents' incomes, the number of children, and custody arrangements. Child support continues until the child reaches the age of majority, typically 18 or 21 depending on the state. It's a legal obligation separate from custody decisions.
