How to File for Divorce in Washington: Residency, Grounds & Waiting Period

In Washington, a divorce is legally called a dissolution of marriage (or dissolution of domestic partnership). You can petition for dissolution if you are a Washington resident, are a member of the armed forces stationed in Washington, or are married or in a domestic partnership to someone who is a resident or a servicemember stationed here. Washington has no durational residency requirement — there is no minimum number of days or months you must have already lived in the state before you file. The only ground you need is that the marriage or domestic partnership is "irretrievably broken," and you do not need your spouse's consent to move forward. Once filed, the court cannot enter a final decree until at least 90 days have passed since both the petition was filed and the summons was served on (or first published to) the other spouse.

Is Washington a no-fault state?

Yes. Washington is a pure no-fault state. The petitioner does not have to prove wrongdoing — adultery, abandonment, cruelty, or anything similar — to obtain a dissolution. The sole legal basis is that the marriage or domestic partnership is irretrievably broken. Because consent from the other spouse is not required, one party can start and finish the process even if the other party disagrees that the marriage should end.

Residency: what you actually need to qualify

Washington's residency rule is intentionally simple. A party may file for dissolution if any one of the following is true:

• The filing party is a resident of Washington;
• The filing party is a member of the armed forces stationed in Washington; or
• The filing party is married or in a domestic partnership to a person who is a Washington resident or who is a member of the armed forces stationed in Washington.

There is no waiting period of a certain number of days or months of residency before you are allowed to file. That said, residency to file is not the same as the court having full authority over every issue in your case. If your spouse has never lived in Washington, that can limit the court's ability to divide certain debts and property or to set spousal support against that spouse, depending on the circumstances. If your case involves children, Washington courts generally need the children to have lived primarily in the state for the last six months for the court to have jurisdiction to enter a parenting plan, under the interstate custody-jurisdiction framework (the UCCJEA). If your children have recently moved to or from another state, this is worth confirming with your local Washington superior court clerk or a family law attorney before you file, since jurisdiction rules can be fact-specific.

Grounds: "irretrievably broken"

Washington does not ask you to explain why the marriage is over. You simply state, in the petition, that the marriage or domestic partnership is irretrievably broken. There is no requirement to show fault, and the other spouse cannot block the dissolution simply by objecting or refusing to agree that the marriage is over.

The 90-day waiting period — time-sensitive

Flag: this is a firm minimum, not a typical timeline. Washington law prohibits the superior court from entering a decree of dissolution until at least 90 days have elapsed from two separate starting points: (1) the date the petition was filed, and (2) the date the summons was served on the respondent, or, if the respondent could not be personally served, the date of first publication of the summons. Both 90-day clocks must run before a judge can finalize the case — so if service is delayed, your effective waiting period is delayed too. Ninety days is a floor, not a promise: contested issues (property, parenting plans, support) commonly push a case well past that point.

Military families: an added protection

Flag: time-sensitive if a spouse is deployed or on active duty. Under the federal Servicemembers Civil Relief Act (SCRA), a servicemember whose military duties materially affect their ability to appear in court — including in a divorce, custody, or support case — can request a stay (a pause) of the proceedings of at least 90 days. This protects an active-duty or deployed spouse or parent from a default judgment being entered against them, or from being forced to litigate while they are unable to participate. If you or your spouse is on active duty and a stay is requested, expect your case timeline to extend beyond the standard 90-day dissolution waiting period.

Property and debts: "just and equitable," not automatically 50/50

Washington is a community property state, but that does not automatically mean everything is split exactly in half. The court divides property and liabilities in whatever manner it finds "just and equitable" after weighing factors that include the nature and extent of the community property, the nature and extent of any separate property, the duration of the marriage, and the economic circumstances of each spouse at the time the division takes effect. In practice this means the court has real discretion, and outcomes vary based on your specific facts — there is no fixed percentage split described in the statute.

Military retirement pay in a Washington divorce

If either spouse has military retired pay, a separate federal law — the Uniformed Services Former Spouses' Protection Act (USFSPA) — allows Washington's courts to treat "disposable retired pay" as property that can be divided in the divorce. USFSPA does not create any federal entitlement to a 50/50 split; how much, if anything, a former spouse receives is still decided under Washington's own "just and equitable" property-division standard described above. Separately, direct payment of a former spouse's share from the Defense Finance and Accounting Service is only available where the couple was married at least 10 years overlapping with at least 10 years of the military spouse's service (sometimes called the "10/10 rule"). Falling short of 10/10 does not prevent a division of retirement pay by the court — it only affects whether DFAS will pay the former spouse directly rather than through the servicemember.

Spousal support ("maintenance")

Washington calls spousal support "maintenance," and it is addressed in its own statute separate from the property-division statute. Because the specific factors and amounts are set out in that separate maintenance statute rather than in the materials summarized here, do not assume a particular dollar figure, percentage, or duration — confirm current maintenance factors with your Washington superior court or a family law attorney for your specific facts.

Modifying a parenting plan later

If you already have a Washington parenting plan or custody decree and circumstances change later, know that Washington courts apply a deliberately high bar to changing it. Generally, a court will not modify a prior parenting plan or custody decree unless it finds — based on facts that arose after the prior decree or plan, or that were unknown to the court at the time — that a substantial change has occurred in the circumstances of the child or a parent. (The statute lists several specific exceptions to this general rule.) This means a parenting plan is not something a court will casually revisit; you generally need a genuine, substantial, and often new change in circumstances.

What you can do in Washington

1. Confirm you qualify to file. Check that you (or your spouse) meet the residency, armed-forces, or domestic-partner criteria described above. There is no minimum residency duration, but if children are involved, confirm they meet the six-month jurisdictional guideline for a parenting plan.
2. Prepare and file the Petition for Dissolution of Marriage and Summons with the clerk of the superior court in the appropriate Washington county. Forms and instructions are available on the Washington Courts website's Court Forms section.
3. Serve your spouse with copies of the filed Summons and Petition. If personal service is not possible, ask the clerk or a family law attorney about service by publication — remember, the 90-day clock for service (or first publication) is separate from the 90-day clock for filing, and both must be satisfied.
4. Note both 90-day dates on a calendar the day you file and the day you (or a process server) complete service, since the court cannot finalize your dissolution until both 90-day periods have passed.
5. If either spouse is active-duty military, be aware the case can be paused for a stay under the SCRA if military duties materially affect that spouse's ability to participate.
6. Gather documentation of property, debts, and income before any hearing on property division or maintenance, since the court's decision on both is based on your specific financial circumstances rather than a fixed formula.
7. If you have a military retirement asset, note whether your marriage overlapped at least 10 years with at least 10 years of the military spouse's service, since that affects only how direct payment works, not whether the asset can be divided at all.
8. For anything not covered by the materials above — specific maintenance amounts, filing fees, or unusual jurisdictional facts — confirm directly with your Washington superior court clerk or a family law attorney before relying on it.
