Filing Family Court Cases from Mercer Island
Mercer Island residents file family law cases at King County Superior Court. RCW Chapter 26.09 governs dissolution and legal separation in Washington. The state is no-fault, so you do not need to prove any wrongdoing. The only required ground is that the marriage is irretrievably broken.
You start by filing a Petition for Dissolution and a Summons at the King County Courthouse. The other party must be served under court rules. If both parties agree on all issues, you can submit an agreed final decree without going to trial. Washington requires a 90-day waiting period after service before the court can enter a final order. Property is divided under community property principles unless the parties reach a different agreement.
Cases involving children require more steps. King County requires both parents to attend an approved parenting seminar before the court signs a parenting plan order. RCW Chapter 26.12 establishes family court jurisdiction in Washington and covers guardian ad litem appointments, parenting seminars, and how judges prioritize cases involving children. King County has a family law facilitator at the courthouse to help self-represented filers understand the process.
All official court forms are free at courts.wa.gov/forms. You can find complete packets for dissolution, child support, parenting plans, and protection orders. The Guide and File tool walks through each form interactively.
The King County family law facilitator can help self-represented filers understand forms and next steps but cannot give legal advice. The facilitator office is at the King County Courthouse in Seattle.
