Washington calls it 'dissolution of marriage,' not divorce, and two things shape almost every case here: community property rules and a mandatory 90-day wait before anything can be finalized.
Washington is one of a small number of true community property states. As a general rule, income earned and property or debt acquired by either spouse during the marriage is presumed to belong equally to both, regardless of whose name is on the account or title. Property owned before the marriage, along with gifts and inheritances kept separate, is generally treated as separate property — but commingling it with joint funds can blur that line quickly, which is why tracing records matter early. Courts divide the community estate in a way that is 'just and equitable,' which in practice usually lands close to an even split but isn't required to be exactly 50/50.
Washington is also a no-fault state: the only ground needed is that the marriage is 'irretrievably broken,' so there's no need to prove wrongdoing. Cases are filed in Superior Court at the county level — King County, Pierce County, Snohomish County, and so on — and each county runs its own local procedures and forms, so it's worth checking your specific county Superior Court's family law website once you know where you'll file.
Washington imposes a mandatory minimum waiting period: a court cannot enter a final dissolution decree until at least 90 days have passed since the petition was filed and served on the other spouse. This is a floor, not an estimate — contested issues, disclosure disputes, or a crowded court calendar routinely push real cases well past 90 days. Treat the 90-day mark as 'the earliest possible,' not a deadline to plan around.
Residency in Washington is comparatively simple: one spouse must currently reside in the state (or be a member of the armed forces stationed here) at the time of filing. Unlike many states, Washington does not require a minimum number of months of residency before you can file — confirm current requirements with your county court or a local family law attorney, since local practice can add wrinkles.
Because Washington starts from a presumption of equal community ownership, thorough records make the process smoother rather than more contentious. Begin collecting: recent pay statements and the last two to three years of tax returns; statements for every bank, investment, retirement, and pension account; mortgage and property tax records for any real estate; vehicle titles and loan statements; and business records if either spouse is self-employed or owns a company. If you're claiming something as separate property — an inheritance, a pre-marriage asset, a personal injury settlement — gather the paper trail showing where it came from and how it's been kept apart from joint funds, since separate-property claims are won or lost on documentation.
Save every letter and email exchanged with the other spouse or their lawyer from the start. In a community property state, a clear record of who proposed what, and when, becomes the backbone of settlement talks — and of any parenting plan negotiations if children are involved.
Washington requires a written Parenting Plan in any case involving minor children, spelling out the residential schedule, decision-making authority, and a dispute resolution process for future disagreements — vague, aspirational plans tend to generate more conflict later than specific, workable ones. Child support is calculated using the Washington State Child Support Schedule, based primarily on both parents' incomes and the number of children, with adjustments for residential time and specific expenses. Many counties encourage or require mediation for contested parenting plan terms before a case goes to trial, so it's worth asking your county court what's expected locally.
1) Start your financial documentation binder now, separating community and potential separate-property items as you go. 2) Confirm your county's residency and filing requirements, since procedures vary between Superior Courts. 3) If children are involved, sketch out what residential schedule and decision-making split would actually work day-to-day, before positions harden. 4) Get at least one consultation with a Washington family law attorney early — many offer limited-scope help for specific steps even if you're otherwise self-representing. 5) Keep every letter and its date organized from day one; with a 90-day floor and no guaranteed finish line beyond it, knowing exactly what's been sent, received, and promised is what keeps the case moving instead of stalling.
Property and debt acquired during the marriage is generally presumed to belong to both spouses equally, while property owned before marriage or received as a gift or inheritance is usually separate — though commingled funds can complicate that. Courts divide the community estate in a way that's just and equitable; confirm specifics with a local attorney.
No. Washington law requires at least 90 days between filing and service of the petition and entry of the final decree. This is a minimum, not a typical timeline — many cases, especially contested ones, take longer.
Washington generally requires that one spouse currently reside in the state (or be military personnel stationed there) at filing, without a fixed durational residency period like some other states use. Court and case specifics vary, so confirm current rules with your county Superior Court or a local family law attorney.
