Filing Fees in Mercer Island
Filing a dissolution of marriage in King County costs around $350. This amount includes state surcharges for various court programs. The fee is paid when you file the initial petition. If you cannot afford it, you can ask for a waiver. King County also has an expedited processing option for document requests that costs $30 extra.
Other costs that come up in a typical dissolution case include process server fees (roughly $50 to $100 if you use a private server), certified copy fees ($5 for the first page, $1 for each additional page), and parenting seminar fees if the case involves children (typically $35 to $75 per person). The sheriff can also serve papers for about $40 to $60 if you prefer using the county.
Fee waivers are available. File a motion and declaration showing your income and expenses. If you receive public benefits or earn below 200% of the federal poverty level, you likely qualify. Forms are at courts.wa.gov/forms. The Washington State Department of Health also sells dissolution certificates by mail for $25, which is cheaper than getting court-certified copies if you only need proof that a dissolution occurred.
The Dissolution Process
Washington State law governs dissolution under RCW Chapter 26.09. The state is purely no-fault. That means neither spouse needs to prove wrongdoing. Stating that the marriage is irretrievably broken is all that is required. The court accepts that and proceeds.
Under RCW 26.09.030, at least one spouse must be a Washington resident or a military member stationed in the state at the time of filing. There is no minimum period of residency within King County specifically. A Mercer Island resident who recently moved from another state may need to wait for Washington residency to attach before filing here.
The case starts with a Petition for Dissolution and Summons. These must be served on the other spouse or that spouse must sign a Joinder. After service, a 90-day waiting period applies before the court can finalize anything. If both parties agree on all issues, the decree can be entered at the end of the waiting period. If there are disputes, the case goes through hearings, possibly mediation, and may take considerably longer. Cases with children always require a parenting plan under RCW 26.09.187. Child support uses state guidelines.
Getting Copies of Records
To get copies of dissolution records from a Mercer Island case, contact the King County Superior Court Clerk. You can go in person to either courthouse, use the KC Record Access Portal online, or mail a written request. Include the names of both parties, the case number if you have it, and a note about which documents you need.
Certified copies are $5 for the first page and $1 per additional page. These carry the court's official seal and are accepted for legal purposes. Non-certified copies are cheaper but less formal. If you only need to look at a document and not take it with you, in-person inspection at the clerk's public terminals is free.
For a dissolution certificate rather than the court file, the Washington State Department of Health handles those for $25 by mail. DOH certificates cover dissolutions from 1968 forward and are often accepted for name changes, passport applications, and similar tasks. The Washington State Digital Archives has some pre-1968 records and historical index information for King County.
