Divorce Rules in Washington State: Filing, Waiting, and Custody

Divorce rules in Washington state start from a simple premise: this is a no-fault jurisdiction, and either spouse can end the marriage by declaring under oath that it is irretrievably broken. One spouse must be a Washington resident on the day the petition is filed, the other spouse must be formally served, and at least 90 days must pass before a judge can sign the final decree. Within that framework, the court divides property, sets support, and approves a parenting plan if children are involved.

Who Can File

At least one spouse has to be a Washington resident on the filing date. Active-duty military members stationed in Washington also qualify, even if their legal home is elsewhere.¹ There is no minimum length of residency. If you moved here last week and plan to stay, you meet the threshold.

You file in the Superior Court of the county where you live. If your spouse lives in a different Washington county, the case still belongs in yours. A Washington resident can also file when the other spouse lives out of state, though the court’s power to divide out-of-state property or order support against that spouse may be limited.

The Only Ground: Irretrievable Breakdown

Washington does not recognize fault-based grounds. There is no filing option for adultery, abandonment, cruelty, or any other misconduct. One spouse’s sworn statement that the marriage is irretrievably broken is enough, and the other spouse cannot block the divorce by arguing the marriage can be saved.¹

The no-fault approach carries into the financial side too. Judges are instructed to divide property and award maintenance “without regard to misconduct.”² Even when one spouse plainly caused the marriage to fail, that fact alone will not shift who gets what.

Filing the Petition

The case opens when you file a Petition for Divorce (Form FL Divorce 201) with the Superior Court clerk.³ The petition asks for both spouses’ names and addresses, the marriage date and place, information about any minor children, and the property and debts you want the court to address.

The base filing fee is $200, with surcharges that bring the total to roughly $364.⁴ If you cannot afford it, you can ask for a waiver. You qualify if you receive public assistance such as TANF or food stamps, or if your household income is at or below 125 percent of the federal poverty guidelines. A judge reviews a financial disclosure form before granting or denying the request.

Serving Your Spouse

After filing, the other spouse must receive formal notice. Washington requires personal delivery of the summons and petition, and the person who filed cannot hand over the papers themselves.⁵ Any other adult can serve, including a friend, a professional process server, or the county sheriff.

Once served, the respondent has 20 days to file a written response if service happened within Washington. That window extends to 60 days for personal service outside the state or for service by publication.⁶ Missing the deadline does not close the case for the respondent, but it lets the petitioner ask for a default judgment on the petition’s terms.

When You Cannot Find Your Spouse

If your spouse has moved, is hiding, or cannot be located despite a reasonable search, you can ask the court for permission to serve by publication. The motion has to document every effort you made to find them, with dates, methods, and results.⁷ If you know their last home address, you must also mail copies of the summons and petition there before publication is authorized.

The court can then approve publication of the summons in a newspaper, which satisfies notice.⁸ One catch: when the other spouse is outside Washington, service by publication often limits the court’s authority to divide property, set support, or enforce restraining orders. The divorce itself can still go through, but financial and custody orders may require further proceedings.

If Your Spouse Is on Active Military Duty

The Servicemembers Civil Relief Act can delay the case. A service member who cannot appear because of military duties can request a stay of at least 90 days, and courts can extend it as long as active duty prevents participation. If the service member has not responded and has no attorney, the court must appoint one before entering a default judgment. These protections are not automatic; the service member or their attorney has to invoke them.

The 90-Day Waiting Period

No divorce in Washington can be finalized until 90 days have passed from the date the petition was filed and the respondent was served.¹ Both conditions have to be met, so if service takes several weeks, the 90-day clock effectively starts on the service date. Even when the spouses agree on every issue the day after filing, the judge cannot sign the decree until the period runs. There are no exceptions and no way to shorten it.

Most contested divorces take much longer than 90 days. The waiting period matters most in uncontested cases where the spouses have already resolved everything and want to finalize quickly.

Dividing Property and Debts

Washington is a community property state. Anything earned or acquired during the marriage generally belongs to both spouses equally. Property owned before the marriage, along with gifts and inheritances received by one spouse, is separate property.⁹ That classification is the starting point, not the finish line.

The court divides both community and separate property using a “just and equitable” standard, weighing four factors: the nature and extent of community property, the nature and extent of separate property, how long the marriage lasted, and each spouse’s economic circumstances at the time of division.² The statute also mentions whether it is desirable to let the parent with primary custody keep the family home, at least for a time.

Just and equitable does not automatically mean 50/50. In a short marriage between spouses with similar incomes, an even split is common. In a long marriage where one spouse sacrificed career advancement to raise children, the court may award that spouse a larger share to account for reduced earning capacity. Debts follow the same analysis, so a spouse in a better financial position may end up with a bigger share of the debt.

One feature of Washington law that surprises many people: judges can award one spouse’s separate property to the other. This typically happens in long-term marriages where the community estate alone is not enough to reach a fair result, particularly when one spouse holds significant separate assets and the other has little ability to support themselves going forward.²

Spousal Maintenance

Maintenance (called alimony in most other states) is not automatic. A court may award it to either spouse after weighing the statutory factors, and misconduct is not one of them.¹⁰ Judges look at what property the requesting spouse received in the divorce and whether they can meet their own needs, how long it would take them to gain the education or training for appropriate work, the standard of living during the marriage, the length of the marriage, the age and physical and emotional condition of the requesting spouse, and whether the other spouse can pay maintenance while still covering their own needs.

Washington has no formula for amount or duration. A judge might award two years of support to help a spouse finish a degree, or indefinite support after a 25-year marriage where one spouse has not worked outside the home in decades. The trend in most cases is toward temporary, rehabilitative maintenance meant to bridge the gap until the recipient becomes self-sufficient.

Parenting Plans When Children Are Involved

When minor children are part of the marriage, Washington requires a formal parenting plan as part of the final decree. Each parent files a proposed plan, and those proposals become the basis for negotiation or, if the parents cannot agree, a court decision.¹¹ The plan covers where the children live day to day and on holidays, which parent makes major decisions on education, healthcare, and religious upbringing, and how future disputes between the parents will be resolved.

A parent who files a proposed plan and gets no response from the other can ask the court to adopt their plan by default. Both proposals must include a signed statement that the plan was submitted in good faith, and the court can order a mandatory settlement conference to narrow disagreements before trial.

Restrictions for Safety Concerns

Washington law imposes mandatory limits on a parent’s time with children when there is evidence of domestic violence, physical or sexual abuse of a child, or a pattern of emotional abuse.¹² These are not discretionary considerations the judge weighs alongside other factors. If the conduct is established, the statute requires residential time limits and can require sole decision-making authority for the other parent.

The restrictions also apply when a parent lives with someone who has a history of these behaviors. Long-term substance abuse that interferes with parenting can also lead to limits on residential time. The court has some flexibility in choosing the level of restriction, but ignoring the issue is not an option once the conduct is proven.

Child Support

Washington calculates child support from an economic table that sets a presumptive amount based on both parents’ combined monthly net income and the number of children. The table covers combined incomes up to $50,000 per month. Above that, the court can order more if it makes written findings explaining why.¹³

For lower-income households with combined income below $2,200 per month, the obligation is based on each household’s resources and expenses rather than the standard table. The minimum cannot drop below $50 per child per month. Each parent’s share is proportional to their share of combined income, so a parent earning 70 percent of the total pays 70 percent of the support amount.

Retirement Accounts and Social Security

Retirement accounts earned during the marriage are community property and can be divided. For employer-sponsored plans governed by federal law, such as 401(k)s and pensions, you need a Qualified Domestic Relations Order to actually split the account. A QDRO directs the plan administrator to pay a portion of the benefit to the non-employee spouse.¹⁴ The order must name the participant and the alternate payee, identify each plan, and specify either a dollar amount or a percentage to be transferred.

Washington state retirement plans through the Department of Retirement Systems follow their own process. DRS can be required to pay a portion of a member’s account to an ex-spouse or split it entirely, but only when a court-ordered property division directs it.¹⁵ Getting the QDRO or state property order right is one of the most technical parts of a divorce, and a poorly drafted order can be rejected by the plan administrator.

Social Security benefits cannot be divided as property, but a divorced spouse may qualify for benefits on an ex’s earnings record. You must have been married at least 10 consecutive years, be at least 62, and be currently unmarried. If your ex has not filed for benefits yet, you must also have been divorced at least two years before claiming.¹⁶ The maximum is 50 percent of the ex-spouse’s full retirement amount, and claiming on their record does not reduce what they receive.

Taxes After Divorce

Your filing status for a given year depends on your marital status on December 31. If the decree is entered any time before year-end, you file as single (or head of household if you qualify) for the whole year. If the decree does not come through until January, you are still married for the prior year and must file jointly or as married filing separately.¹⁷

Spousal maintenance payments carry no tax consequences for either party in divorces finalized after 2018. The paying spouse cannot deduct the payments, and the receiving spouse does not report them as income.¹⁸ Any Washington divorce finalized in 2019 or later falls under the current rule.

For parents sharing custody, only one parent can claim the child tax credit for a given child in a given year. The default rule is that the parent who had the child more than half the year gets the credit. Parents can agree to let the noncustodial parent claim it, but that requires IRS Form 8332 signed by the custodial parent. Working out who claims which child, and in which years, is worth addressing in the divorce agreement rather than fighting about it every April.
