Child Support in Island County: A 2026 Guide
Understanding child support in Island County, Washington requires navigating both uniform state law and specific local court procedures. The unique geographical nature of Island County, accessible by ferry from the mainland, adds an additional logistical consideration. Under Washington's Revised Code (RCW 26.19), child support obligations are calculated using an Income Shares Model. A methodology designed to ensure that children receive a level of financial support proportionate to what they would have enjoyed if their parents had remained together.
In 2026, the Washington State Administrative Office of the Courts (AOC) updated the mandatory child support economic tables that all Island County courts must use. These tables cap at a combined monthly net income of $50,000 and set a firm Self-Support Reserve (SSR) of approximately $2,394 per month — a critical poverty-protection threshold that prevents courts from issuing orders that would impoverish the paying parent.
