Washington court costs
Formal probate costs $290 statewide: a $200 base fee plus $40 and $50 surcharges that the same section makes mandatory for probate filings.
$290 is the amount the statute states. Sources reviewed August 7, 2026. Latest primary-source re-fetch October 3, 2026.
Every line below is computed from the statutory schedule quoted at the end of this page. These are court charges only. They are not an estimate of the total cost of settling an estate.
| Charge | $25,000 estate | $100,000 estate | $400,000 estate | $1,000,000 estate |
|---|---|---|---|---|
| Superior court filing fee, first document | $200 | $200 | $200 | $200 |
| Judicial stabilization surcharge, subsection (5)(c) | $40 | $40 | $40 | $40 |
| Clerk operations surcharge, subsection (6) | $50 | $50 | $50 | $50 |
| Total from this schedule | $290 | $290 | $290 | $290 |
The surcharges are not optional. Subsection (5)(c) applies to all fees under this section except (2)(b), (d) and (h), and subsection (6) lists (2)(f) expressly, so both attach to a probate filing.

Washington’s $290 figure is not a single line. It is the sum of the separate charges below, each set by its own part of the Washington fee provision. Every one is a permanent, statewide charge on opening this kind of case, which is why they combine into one number a filer can check rather than take on trust.
Added together, these come to $290 — the figure this page headlines. If any component changed in the source, the sum would no longer match, and the build withholds the total rather than publishing a number whose parts no longer add up.
These amounts appear in or beside the same Washington schedule, so a reader can easily mistake one for part of the fee. Each is held out of the figure above for the specific reason given, which is the difference between an honest total and an inflated one.
The Washington caveats are listed once, on the Washington overview.
