Increase Child Support in Washington

Requesting an increase in child support in Washington typically involves filing a modification based on a substantial change in circumstances since the last order. These cases depend on updated financial information, accurate child support worksheets, and clear documentation of what has changed. This page focuses on the filings used to request an increase and how those documents are prepared and structured. For full child support services and document preparation options, see our Child Support page.

When a Child Support Increase May Be Requested

An increase request is commonly based on a substantial change in circumstances since the most recent child support order. That change may involve income, expenses, the parenting schedule, or the child’s needs.

Common reasons people request an increase

• Income changes: one parent’s income increased, new employment, bonuses, or changes in earning capacity.
• Parenting schedule changes: residential time shifted and the worksheet should reflect the current schedule.
• Higher child-related costs: daycare, health insurance premiums, uncovered medical, transportation, or other recurring expenses.
• Special circumstances: extraordinary medical needs, therapy costs, or special education-related expenses.
• New information: income or assets were not accurately disclosed when the current order was entered.
