How to Modify Child Support in Washington

Washington requires a 25% or greater change in income to qualify for a modification review. Other qualifying circumstances include:

  • Significant change in custody or parenting time
  • Child's needs have substantially changed
  • Job loss or major income reduction
  • Three years have passed since the last order (automatic review period)
⚠️ Never stop paying support without a court order. Arrears accrue at 12%/year interest in Washington. File for modification immediately if your circumstances change.
