When you pay child support in Washington, the amount is based on a calculation that uses both parents' monthly income as a determining factor, as well as the number and ages of the children involved. The court uses the state guidelines to arrive at the figure, which is presumed correct.

However, there are times when the child support order is already in place, but the obligation no longer reflects the amount that should be paid because conditions have changed. Suppose a parent has been downsized and has taken a lesser-paying job or they have to act as a caregiver for an ailing parent. The court does take these changes in consideration in terms of child support obligations and usually requires the change of circumstances to modify support.

But the child support modification doesn't happen automatically except that the law provides for a review and possible adjustment every two years. If two years have passed from the date of the entry of the order or since the last modification (whichever is most recent), it may be adjusted without showing a substantially changed circumstance and is based on changes in income or state guidelines.

In Washington, either parent can modify an existing child support order. You can modify it by taking two different actions: either file a motion for adjustment of child support or submit a petition to modify child support. Both procedures have specific requirements and you can file one or another, depending on the specific situation.
