Washington Custody Filing Fees Explained: $310–$364 Just to Walk in the Door
Cost Analysis · By Gale McArthur · 2026-04-04 · 7 min read
Before your attorney bills a single hour, Washington courts charge $310–$364 just to file. Here's every fee you'll face — and how fee waivers under GR 34 actually work.
The first financial shock of custody litigation comes before you even see a courtroom. Washington's filing fee system creates an immediate barrier to access — one that disproportionately affects the parent with fewer resources.

The human cost behind the numbers
Current Filing Fees by Type
Based on actual county clerk fee schedules (King County and Yakima County examples):
| Filing Type | Fee | |---|---| | Dissolution of marriage | $364 (King County) | | Parentage (Uniform Parentage Act) | $310 | | Modification of King County decree | $56 | | Modification of non-King County decree | $310 | | Minor guardianship petition | $310 | | Notice of appeal | $290 | | Clerk's papers (per page) | Varies by county | | Record transmittal to appellate court | Additional fees |
The Hidden Fee Stack
Filing fees are just the beginning. Add service of process costs ($50–$150 per attempt), certified copies ($5–$25 each), and administrative fees, and the "entry cost" can reach $500–$1,000 before any substantive legal work begins.
For parents who need to file multiple actions (temporary orders, restraining orders, modifications), fees compound quickly.
Fee Waivers Under GR 34
Washington General Rule 34 establishes a process to waive civil filing fees and surcharges for qualifying low-income parties. Key points:
- Who qualifies: Generally, parties receiving public assistance or whose income falls below federal poverty guidelines
- What's covered: Filing fees and surcharges within the court's authority
- What's NOT covered: Attorney fees, GAL costs, evaluation costs, service costs
- How to apply: File a motion with supporting financial documentation
The critical limitation: GR 34 fee waivers address entry costs only — they do nothing about the $30,000–$250,000 in professional fees that drive contested cases.
County-by-County Variation
Filing fees can vary by county. While the base statutory amounts are similar, counties may add local surcharges or have different fee structures for specific filing types. Always check your county clerk's fee schedule before filing.
Notable examples from published fee schedules: - King County: Higher base fees but more court-connected services with capped costs - Yakima County: Comparable parentage/adoption fees ($310), clerk/facilitator fees add small but real costs - Snohomish County: Similar fee structure with county-specific administrative charges
The Modification Fee Trap
One of the most troubling fee structures involves modifications. If the original decree was entered in King County, a modification costs just $56. But if the original decree was from another county, the modification filing fee jumps to $310 — even if you're now in King County.
This creates an absurd situation where the cost of seeking a change to your child's parenting plan depends on which county originally handled your case.
What This Means for Families
Filing fees represent less than 1% of total litigation costs in contested cases, but they serve as a gatekeeping mechanism that determines who can even begin the process. For a parent earning minimum wage, a $364 filing fee represents nearly two full days of gross pay.
Combined with the inability of fee waivers to cover the real cost drivers (attorneys, GALs, evaluators), the filing fee system creates a two-tiered access structure: those who can afford to enter the system, and those who cannot.
