If you live in Renton and are starting a divorce, your case is handled by the King County Superior Court, but not at a courthouse inside Renton itself. There is no Superior Court building in Renton. Family law cases for Renton, Kent, and Federal Way are assigned to the Maleng Regional Justice Center (MRJC) in Kent, the south-county facility that serves everyone below Interstate 90 except the zip codes routed to downtown Seattle. The current filing fee is $314, and Washington requires a 90-day cooling-off period before any divorce can be finalized.
This page explains where Renton residents actually file, what it costs to hire a divorce lawyer locally, how long the process takes, and the Washington statutes that govern property and parenting. Renton sits along the south shore of Lake Washington, and residents from neighborhoods like the Highlands, Kennydale, Talbot, and the Cedar River valley all route to the same Kent courthouse roughly 15 to 20 minutes south via SR 167 or I-405.

How do I file for divorce in Renton, Washington?
To file for divorce in Renton, submit a Petition for Dissolution of Marriage to King County Superior Court and pay the $314 filing fee, then serve your spouse. Washington is a pure no-fault state under RCW 26.09.030, so you only need to state the marriage is irretrievably broken. No proof of wrongdoing is required, and your spouse cannot block the divorce by objecting.
The filing packet for a Renton case includes the Petition, a Summons, a Confidential Information Form, and, if you have children, a Proposed Parenting Plan and Child Support Worksheets. You can file in person at the Maleng Regional Justice Center clerk's office in Kent (Room 2C) or electronically through Washington's e-filing system. After filing, you must serve your spouse, usually through a process server or sheriff, which typically adds a $40 to $75 service cost. The 90-day clock starts on the later of the filing date or the service date, so prompt service matters. If you cannot afford the $314 fee, you can submit a Motion and Declaration for Waiver of Civil Fees based on indigency under GR 34 and RCW 36.18.022, and the forms are free at the MRJC Family Law Facilitator's office in Room A-1222.
Where do I file for divorce in Renton? (which courthouse)
Renton residents file at the Maleng Regional Justice Center, 401 Fourth Avenue North, Kent, WA 98032. King County Superior Court assigns south-county family law cases (Renton, Kent, Federal Way, and everything below I-90 except Seattle-routed zip codes) to this Kent facility rather than the downtown Seattle courthouse at 516 Third Avenue.
The MRJC is a full-service courthouse: it handles dissolutions, child support, parentage, adoptions, and domestic-violence protection orders for the southern half of King County. The Superior Court Clerk's office is in Room 2C, and the Family Law Facilitator's office (which provides free forms and procedural guidance but not legal advice) is in Room A-1222. Free parking is available in the on-site garage, though it often fills by 8:30 a.m., so arriving early is wise for any hearing. The courthouse is about 8 miles south of downtown Renton, a 15-to-20-minute drive depending on SR 167 traffic. Note that the building sits in Kent despite serving Renton; there is no separate Renton Superior Court, so do not attempt to file at Renton City Hall or the Renton Municipal Court, which handle only city matters like traffic and misdemeanors, not divorce.
How much does a divorce lawyer cost in Renton?
A divorce lawyer in Renton typically charges $300 to $450 per hour, with most family law attorneys requesting an upfront retainer of $3,500 to $7,500. An uncontested Renton divorce handled by counsel often totals $2,500 to $5,000, while a contested case involving custody or significant property disputes commonly runs $15,000 to $30,000 or more.
These figures reflect the King County market, where rates run higher than rural Washington counties. The biggest cost driver is conflict: every contested motion, deposition, and trial day adds billable hours. A truly uncontested dissolution where both spouses agree on everything can sometimes be completed with limited-scope (unbundled) attorney help for under $2,000 plus the $314 court fee. If you and your spouse agree on the major terms, you can keep costs near the statutory minimum. Many Renton attorneys offer flat-fee packages for uncontested cases and free or low-cost initial consultations. For Renton residents who cannot afford full representation, the King County Bar Association's Neighborhood Legal Clinics and the Northwest Justice Project provide free legal help based on income.

How long does a divorce take in Renton?
The fastest a Renton divorce can finalize is 90 days, the mandatory waiting period set by RCW 26.09.030. This cooling-off period runs from the later of the filing date or the date your spouse is served, and it cannot be waived by agreement or by the court under any circumstances, including cases involving domestic violence.
In practice, most uncontested Renton cases take 3 to 4 months, because court scheduling and final paperwork extend slightly beyond the 90-day floor. Contested divorces move much slower: cases involving disputed custody or property at the Maleng Regional Justice Center typically take 9 to 18 months, and high-conflict custody trials can exceed 24 months. Washington has no separation requirement, so you do not need to live apart for any period before filing. A 2024 statutory provision in RCW 26.09.030 also clarifies that a court cannot use a party's pregnancy as the sole basis for denying or delaying entry of a divorce decree. To shorten your timeline, complete and exchange financial disclosures early and reach written agreement on as many issues as possible before the 90 days elapse, so the court can enter final orders the moment the waiting period ends.
What are the residency requirements to file in King County?
Washington has unusually flexible residency rules: at least one spouse must be a Washington resident (or a service member stationed here), but there is no minimum length of residency. You can file in King County the day you establish residence. This is far more lenient than the six-month or one-year requirements common in other states.
For a Renton case to be filed at the Maleng Regional Justice Center, you should reside in the south King County area below I-90. One important caveat involves jurisdiction over an out-of-state spouse: while Washington can dissolve the marriage as long as one spouse lives here, the court's power to divide property or order support may be limited if your spouse has never lived in Washington and lacks sufficient contacts with the state. In those situations, the court can still grant the divorce itself but may not be able to reach the absent spouse's assets. If your spouse lives in another state, raise this jurisdictional issue with a Renton attorney before filing, because it affects where you can litigate property and support.
How is property divided in a Renton divorce?
Washington is a community property state, but property is divided equitably, not necessarily equally, under RCW 26.09.080. The court divides all assets and debts, both community and separate, in a way that is just and equitable after weighing the length of the marriage, each spouse's economic circumstances, and the nature and extent of the community and separate property.
Equitable does not mean a strict 50-50 split. A King County judge has discretion to award one spouse a disproportionate share based on the statutory factors, such as the desirability of letting the parent with primary residential time keep the family home in a Renton neighborhood like the Highlands or Kennydale. Marital misconduct, including an affair, is excluded from the property analysis under RCW 26.09.080 unless that conduct actually depleted marital assets (for example, spending community funds on an affair). Separate property generally includes assets owned before marriage or received by gift or inheritance, but it can become commingled and subject to division if mixed with community funds over a long marriage. The property division tool below can help you organize assets and debts before negotiating.
