Washington divorce laws are no-fault, community-property rules administered by the Superior Court in each county, with a mandatory 90-day wait between filing and a final decree. One spouse states that the marriage is irretrievably broken, the court divides assets and debts in a way it considers just and equitable, and if children are involved, a parenting plan replaces the older language of custody and visitation. Nothing about who caused the breakup changes the outcome.
Who Can File and on What Grounds
Washington recognizes a single ground for ending a marriage: the relationship is irretrievably broken. Under RCW 26.09.030, the petitioning spouse alleges that the marriage cannot be repaired, and the court proceeds from there. Proof of infidelity, abandonment, or any other misconduct is neither required nor relevant.1Washington State Legislature. RCW 26.09.030 – Petition for Dissolution of Marriage or Domestic Partnership If both spouses agree the marriage is over, the decree follows once procedural requirements are satisfied. If one disagrees, the court weighs the circumstances and can still grant the dissolution.
At least one spouse must be a Washington resident or a member of the armed forces stationed in the state. A spouse married to someone who meets either condition also qualifies. The statute sets no minimum length of residency.1Washington State Legislature. RCW 26.09.030 – Petition for Dissolution of Marriage or Domestic Partnership
The 90-Day Waiting Period
No judge can sign a final decree until 90 days have passed from both the filing of the petition and the completion of service on the other spouse.1Washington State Legislature. RCW 26.09.030 – Petition for Dissolution of Marriage or Domestic Partnership This clock runs even when both spouses agree on every issue from day one. The earliest a decree can be entered is the ninety-first day.2Washington State Legislature. RCW 26.09.150 – Decree of Dissolution, Legal Separation, Declaration of Invalidity
During the wait, the court can hold temporary hearings to set interim support, a temporary parenting schedule, or restraining orders. Many couples use the three months to mediate, which tends to resolve disputes faster and more cheaply than trial. Contested cases often run far longer than 90 days.
How Property and Debt Are Divided
Washington is a community property state. Most assets and debts acquired during the marriage belong equally to both spouses regardless of whose name appears on the title or account. Property one spouse owned before the marriage, inherited individually, or received as a personal gift is generally separate.
What surprises many people: the court has authority to divide both community and separate property. Under RCW 26.09.080, the judge must reach a disposition that is “just and equitable” after weighing all relevant factors, and just and equitable does not automatically mean a 50/50 split.3Washington State Legislature. RCW 26.09.080 – Disposition of Property and Liabilities The factors include:
- The nature and extent of the community property.
- The nature and extent of each spouse’s separate property.
- The duration of the marriage, since longer marriages tend to produce more intertwined finances.
- The economic circumstances of each spouse at the time the division takes effect, including whether the spouse with primary custody of the children should remain in the family home.
Fault has no place in this analysis. A spouse who caused the breakdown of the marriage receives the same property consideration as the other. Debts follow the same framework, with the judge assigning responsibility for mortgages, credit cards, and other obligations on the same equitable basis.
Spousal Maintenance
Washington has no formula for spousal maintenance, called alimony in some other states. Under RCW 26.09.090, courts have broad discretion to award maintenance based on one spouse’s need and the other’s ability to pay. Factors include the length of the marriage, each spouse’s financial resources and earning capacity, the standard of living established during the marriage, and the time a spouse may need to obtain education or training for appropriate employment.
Maintenance can be temporary, lasting only through the divorce process, or long-term when one spouse significantly sacrificed career development during the marriage. Awards can be modified later if circumstances change substantially. No fixed duration is tied to years of marriage, which makes maintenance one of the less predictable parts of a Washington divorce.
Parenting Plans Instead of Custody
Washington does not use the words “custody” or “visitation” in its orders. Instead, the court enters a Parenting Plan that spells out where the children live and when, who makes major decisions, and how disputes between parents get resolved. The child’s best interests govern every piece of it.4Washington State Legislature. RCW 26.09.002 – Policy
The residential schedule is the core of the plan. It specifies the days and overnights each parent has throughout the year, including holidays, school breaks, and summer. Parents who agree can submit their own schedule, but the court reviews every proposal before signing off.
The plan also allocates decision-making authority over education, healthcare, and religious upbringing. The court can assign these decisions to one parent, both parents jointly, or split them by category, depending on whether the parents have cooperated historically and can realistically continue to do so.5Washington State Legislature. RCW 26.09.184 – Permanent Parenting Plan
The statute requires the court to restrict a parent’s residential time where serious concerns exist, including a history of domestic violence, sexual or physical abuse, a pattern of neglect, or substance abuse problems that interfere with parenting. Restrictions range from supervised visits to a bar on overnight stays, and the court can condition any residential time on drug or alcohol treatment.
How Child Support Is Calculated
Washington uses the Income Shares Model, which aims to give children the same share of parental income they would have received if both parents lived together. The calculation starts with the combined monthly net income of both parents and applies the Washington State Child Support Schedule to produce a baseline obligation.6Washington State Legislature. RCW 26.19 – Child Support Schedule
Each parent’s share is proportional to their income. If one parent earns 60% of the combined income, that parent owes roughly 60% of the basic support amount. Both parties complete Child Support Worksheets accounting for mandatory deductions such as taxes, Social Security, and healthcare premiums. The number of children and their ages also move the final number.
Deviations from the standard calculation can occur when a parent has the children for a significantly greater share of overnights, when extraordinary medical or educational expenses exist, or when a child has special needs. The court must document the reason for any deviation in writing.7Washington State Legislature. RCW 26.19.071 – Standards for Determination of Income
Changing Orders After the Decree
Child support, parenting plans, and spousal maintenance can all be modified when circumstances change substantially. A job loss, a significant raise, a relocation, or a shift in a child’s needs can all support revisiting the original order.
For child support, the court generally looks at whether the existing obligation would be materially different under the current schedule. The parent requesting a change files a petition and provides updated financial information. Parenting plan modifications face a higher bar: the moving parent typically has to show a substantial change in circumstances and that the proposed modification serves the child’s best interests. That threshold protects children from constant schedule upheaval driven by parental conflict rather than genuine need.
Forms, Filing, and Service
Opening a case starts with three core documents: a Summons (FL Divorce 200) that formally notifies the other spouse, a Petition for Divorce (FL Divorce 201) that states what you are asking the court to do, and a Confidential Information Form (FL All Family 001) that keeps sensitive identifiers like Social Security numbers out of the public record. All of these are on the Washington Courts website.8Washington State Courts. Court Forms: Divorce (Dissolution)
If child support, maintenance, or attorney fees are at issue, add a Financial Declaration (FL All Family 131). Back it up with tax returns from at least the past two years and recent pay stubs. These records verify the income figures that feed the support worksheets and give the court an accurate picture of each spouse’s finances.
You file the paperwork with the Superior Court Clerk in the appropriate county and pay the filing fee. Fees vary by county, so confirm the amount with the local clerk; if you cannot afford it, you can request a waiver. Then arrange for someone to deliver the documents to your spouse. The person serving the papers must be at least eighteen and not a party to the case, which usually means a professional process server or a sheriff’s deputy.9Washington State Legislature. RCW 4.28.080 – Summons, How Served A proof of service form then goes to the court to confirm the notification, and the 90-day clock begins to run.
