For the actual documents, you need either a paid download or an in-person request.
To search, you will need at least one of the following:
- Full name of at least one spouse (last name, first name)
- The case number if you have it
- Approximate filing year
The statewide Odyssey portal at odysseyportal.courts.wa.gov also works for King County searches. You can use either tool to find Mercer Island cases. King County's own eCourt system sometimes has more detailed options for family law case filtering.
Mercer Island Divorce Decree Filing Process
Mercer Island residents file for dissolution under Washington State law, specifically RCW Chapter 26.09. The process starts at King County Superior Court. Every step generates documents that become part of the permanent case file.
Washington requires at least one spouse to be a state resident or an armed forces member stationed here. There is no minimum county residency period. Under RCW 26.09.030, the only ground for dissolution is that the marriage is "irretrievably broken." You do not need to prove fault or bad conduct by either party. This no-fault standard makes the legal threshold low, even if the process can still be complex.
The filing spouse submits a Petition for Dissolution and a Summons at the King County Courthouse. The other spouse must be served or sign a Joinder. Washington imposes a 90-day waiting period from the date of service before the court can finalize the dissolution. If both parties agree on all terms, an agreed decree can move through the process faster than a contested case. Contested cases may need mediation, hearings, or a trial before the judge enters the final Decree of Dissolution.
If children are involved, a parenting plan is required. King County requires both parents to complete a parenting seminar. Child support follows the state guidelines in RCW Chapter 26.19, based on both parents' income and the number of children.
King County Superior Court has a Family Law Facilitator in Room W-291 at the Seattle courthouse. Call (206) 263-3542 to ask about their services. The facilitator can help self-represented parties understand court procedures.
