King County Divorce Process: Filing Steps, Family Law Orientation, and Local Rules
King County has the busiest family law docket in Washington State, and its Superior Court imposes several local rules that do not apply in other counties. If you are filing for divorce in King County — whether you live in Seattle, Bellevue, Renton, or Kent — there are mandatory steps beyond the standard statewide process that you must complete or risk having your case stalled.
Step 1: File Your Petition ($364 Filing Fee)
Filing happens at the King County Superior Court Clerk's Office in downtown Seattle, or electronically through the King County e-Filing Portal. The filing fee is $364 (the statewide base fee plus King County's local surcharges).
If you cannot afford the fee, you can file a Motion and Declaration for Waiver of Civil Filing Fees under General Rule 34. You will need a completed financial statement showing your household income is at or below 125% of the federal poverty guidelines.
Once filed, the Clerk issues a case number and an automated Order Setting Domestic Case Schedule. This document contains strict local deadlines specific to your case — track them carefully.
Step 2: The Mandatory Family Law Orientation
King County requires every self-represented party in a family law case to attend a Family Law Orientation session. This is an informational class that explains how the court process works, what resources are available, and what the court expects from unrepresented litigants.
Key details:
- Offered online through the King County registration and video program
- Takes approximately one hour
- Complete it by the deadline on your Case Schedule; local rules generally require completion within 30 days of filing or service
- $20 per person plus processing fees; eligible parties can request a fee waiver
- Registration is through the King County Superior Court website
This is separate from the mandatory parenting seminar. If you have minor children, you must also complete the "What About the Children" parenting class within 60 days of service — a four-hour course currently offered online through Zoom.
Step 3: Serve Your Spouse
Standard Washington service rules apply: personal service by a third party over 18, acceptance of service signed by your spouse, or (if your spouse cannot be located) court-ordered service by mail or publication.
The 90-day mandatory waiting period starts on the later of your filing date or the date your spouse is properly served or joins the action. King County cannot shorten this timeline.

Step 4: The Simple Dissolution Program
King County offers a streamlined Simple Dissolution Program for couples who meet all of these criteria:
- No minor children
- No real estate
- Limited community assets and debts
- Both parties are self-represented
- Both parties agree on all terms
If eligible, you work directly with courthouse facilitators who review your forms and present them to a judicial officer in chambers. This eliminates the need for a court hearing entirely. If any dispute arises during the process, you are disqualified from the program and must proceed through the standard calendar.
Step 5: Finalization Without a Hearing (Declaration in Lieu of Formal Proof)
Some Washington counties require at least one spouse to appear before a judge to "prove up" the divorce — brief testimony under oath confirming the basic facts. King County allows you to skip this by filing a Declaration in Lieu of Formal Proof.
In this declaration, both parties verify under penalty of perjury: the date of marriage, date of separation, that the marriage is irretrievably broken, that neither party is pregnant, and that both agree to the terms in the proposed final orders. Courthouse facilitators then present the paperwork to a judge in chambers, and you receive your signed final decree by mail.
This saves a trip to the courthouse and eliminates the scheduling delay of getting onto the uncontested dissolution calendar.
King County-Specific Pitfalls
The Case Schedule is not optional. The automated Order Setting Domestic Case Schedule includes deadlines for disclosure of assets, completion of mediation (if applicable), and readiness for trial. Missing these deadlines can result in sanctions or case dismissal.
Facilitator appointments may require orientation first. Check the current King County instructions before requesting an appointment. Facilitators review your documents for completeness and formatting — they do not give legal advice but can catch errors that would cause a rejection.
E-filing has specific formatting requirements. Check the current portal instructions for PDF format, separate-file uploads, and any restrictions on combined documents.
