The SSR and Low-Income Safeguards
In 2026, the SSR remains a vital safeguard. When the combined income is $2,500, the court ensures the $543 payment doesn't violate the $2,394 rule, protecting the payor's ability to live.
Filing in King County Superior Court
In King County Superior Court, located in Seattle, child support orders based on a $2,500 combined income are filed with theKing County Superior Court clerk at 516 3rd Ave, Room E-609, Seattle, WA 98104. Filing fees inKing County are $314. Once filed, the presumptive$543/mo order for one child becomes the baseline unless either parent requests a deviation hearing.
Income Bracket Context
At $2,500/mo, this household falls in the lower income bracket of Washington's 2026 schedule — below the state median of $7,114/mo. At this level, SSR protections and low-income deviations are more likely to influence the final order than the presumptive $543 figure.
Deviation Likelihood in King County
At the $2,500 level, deviation requests are less common but still possible in King County. The most frequent grounds are extraordinary healthcare costs, shared custody arrangements, or documented debts. The presumptive $543 is upheld in the majority of standard cases at this income tier.
Children-Specific Insight

These neighboring brackets help illustrate how Washington's 2026 schedule scales support incrementally with income.
