Seattle Divorce Lawyers

Getting divorced in Seattle means filing in the largest trial court in Washington: the Superior Court of Washington for King County. If you live in Seattle, Bellevue, Mercer Island, Issaquah, or anywhere north of Interstate 90, your dissolution case is handled at the King County Courthouse in downtown Seattle, not the Kent regional center. This page covers exactly where to file, what it costs, how long it takes, and what a Seattle divorce lawyer does, with current 2026 figures and the controlling Washington statutes.

Seattle sits in King County, the most populous county in Washington with roughly 2.3 million residents. The downtown courthouse on Third Avenue serves the northern half of the county, and your case receives a "Seattle" designation based on your residence. Knowing which building serves your neighborhood matters: filing at the wrong location can delay your case schedule and your hearing dates.

Key Facts: Seattle (King County) Divorce at a Glance

How do I file for divorce in Seattle, Washington?

To file for divorce in Seattle, you submit a Petition for Dissolution of Marriage and a Summons to the King County Superior Court Clerk, pay the approximately $314 filing fee, and serve your spouse. Washington is a pure no-fault state, so the only ground is that the marriage is "irretrievably broken" under RCW § 26.09.030. Only one spouse needs to assert this.

The process follows a clear sequence. First, complete the petition along with a confidential information form and, if you have minor children, a proposed parenting plan and child support worksheet. Second, file with the Clerk at Room E-609 or through the Washington State e-filing portal. The Clerk issues a case schedule listing every deadline and your trial date. Third, serve your spouse personally or secure a signed acceptance of service. If your spouse joins the petition, the case proceeds as uncontested. King County also runs a Simple Dissolution program under local rule LFLR 21 for couples with no children, no real property, and full agreement, which streamlines the paperwork considerably.

Where do I file for divorce in Seattle? (which courthouse)

Seattle residents file at the King County Courthouse, 516 Third Avenue, Room E-609, Seattle, WA 98104. The Clerk's Office sits on the sixth floor. This downtown location handles all family law cases filed north of Interstate 90, including Seattle, Bellevue, Mercer Island, Issaquah, and North Bend. Cases get a "Seattle" designation accordingly.

King County operates two Superior Court family law locations, and choosing correctly is essential. If you live south of I-90, including Kent, Renton, or Federal Way, you file at the Maleng Regional Justice Center, 401 Fourth Avenue North, Room 2C, Kent, WA 98032, and your case takes a "Kent" designation. The downtown Seattle courthouse is steps from Pioneer Square and the Chinatown-International District, accessible via the Pioneer Square light rail station. The Family Law Facilitator Program at the Seattle courthouse (Room W-291, phone 206-477-2553) helps self-represented filers with forms and fee waivers. The Clerk's main line is 206-296-9300, open Monday through Friday.

How much does a divorce lawyer cost in Seattle?

A Seattle divorce lawyer typically charges $250 to $450 per hour, with most family law attorneys requesting a retainer of $3,000 to $7,500 up front. An uncontested divorce with limited attorney involvement often totals $1,500 to $4,000, while a contested case involving custody disputes, property valuation, or business interests commonly runs $15,000 to $30,000 or more.

Seattle's cost of living pushes legal rates above the Washington state average. Several factors drive the final bill: whether the divorce is contested, the complexity of property division, whether minor children require a parenting plan, and whether experts such as forensic accountants or custody evaluators are needed. The mandatory court filing fee of approximately $314 is separate from attorney fees. If you cannot afford the filing fee, you can request a waiver under General Rule 34 using forms available free at the Clerk's Office or the Family Law Facilitators Office. To estimate your total exposure before hiring counsel, use the divorce cost estimator. Many Seattle attorneys offer free or low-cost initial consultations, and unbundled "limited scope" representation can reduce costs for filers who handle routine tasks themselves.

How long does a divorce take in Seattle?

The minimum time for a Seattle divorce is 90 days, the mandatory waiting period required by RCW § 26.09.030. This clock starts on the later of the filing date or the date your spouse is served, and it cannot be waived under any circumstances, even when both spouses fully agree.

In practice, timelines vary widely. An uncontested Seattle divorce where both spouses sign agreements on property, support, and parenting can finalize shortly after the 90-day window closes, often in three to four months. Contested cases that proceed toward trial frequently take 12 to 18 months because King County issues a case schedule with structured deadlines for disclosure, mediation, and pretrial motions. The downtown courthouse's high case volume can add scheduling delays. Washington has no separation requirement, so spouses may live together during the entire waiting period without affecting the timeline. Use the divorce timeline tool to map your expected milestones based on whether your case is agreed or disputed.

What are the residency requirements to file in King County?

Washington has no minimum residency duration. Under RCW § 26.09.030, you may file for dissolution in King County if either spouse resides in Washington, or is a member of the armed forces stationed in Washington, on the date of filing. You simply need to live in Washington with intent to make it your permanent home.

This makes Washington one of the most accessible states in the nation for divorce filing. Many states impose six-month or one-year residency waits, but Washington imposes none, so a new Seattle resident can file immediately. Venue is proper in King County when at least one spouse resides there. One jurisdictional caveat applies: under RCW § 26.09.080, if the responding spouse lives outside Washington and lacks sufficient minimum contacts with the state, the court may dissolve the marriage and establish a parenting plan but have limited authority to divide out-of-state property or order spousal maintenance against that spouse.

How is property divided in a Seattle divorce?

Washington is a community property state, but division is not automatically 50/50. Under RCW § 26.09.080, a King County judge divides all property and liabilities, both community and separate, in a manner that is "just and equitable." Courts value property as of the date of trial, not the date of separation.

Judges weigh statutory factors including the length of the marriage, each spouse's economic circumstances, contributions as a homemaker, and the desirability of awarding the family home to the parent who has the children most of the time. A valid prenuptial or postnuptial agreement under RCW § 26.09.070 can override the default community property framework. For families with children, Washington uses parenting plans rather than "custody" orders. Under RCW § 26.09.187, the court applies a seven-factor best-interests standard, giving the greatest weight to the strength and stability of each parent's relationship with the child. Recent reform under House Bill 1620, effective July 27, 2025, strengthened protections in cases involving domestic violence and added "abusive use of conflict" as a factor that can limit a parent's residential time. Child support follows the Washington State Child Support Schedule under RCW 26.19, and 2026 guidelines under Engrossed House Bill 1014 expanded the support table to cover combined monthly incomes up to $50,000.
