Getting Divorced with Children in Washington (2026 Guide)

Getting divorced with children in Washington requires a court-approved parenting plan, a mandatory 90-day waiting period, and a child support order calculated under the 2026 economic table. Washington charges a divorce filing fee of roughly $280 to $400 (about $314 in most counties), has no minimum residency duration, and replaces the word "custody" with a residential schedule decided under the child's best interests per Wash. Rev. Code § 26.09.187.

Washington is a no-fault dissolution state. Neither spouse must prove wrongdoing; the only ground is that the marriage is "irretrievably broken" under Wash. Rev. Code § 26.09.030. When minor children are involved, the divorce cannot finalize until a permanent parenting plan and child support order are entered. This guide explains how divorce with children works in Washington, what the parenting plan must contain, how child support is calculated under the major 2026 reforms, and how relocation, modification, and timelines affect families.

How Divorce With Children Works in Washington

Divorce with children in Washington begins when one spouse files a Petition for Dissolution in the superior court of the county where either spouse lives. The case cannot finalize for at least 90 days after filing and service under Wash. Rev. Code § 26.09.030, and when minor children exist, the court will not enter a final decree without an approved parenting plan and child support order.

Washington's no-fault system means the court does not assign blame. The petitioner states only that the marriage is irretrievably broken, and the state imposes no separation requirement — spouses may even live together during the 90-day period. The process for a divorce with children Washington families face involves filing the petition, serving the other spouse, filing proposed parenting plans and child support worksheets, completing any required parenting class, and either reaching a settlement or proceeding to trial. Most counties also require financial disclosure and may mandate mediation before trial. Because children are involved, families typically file a temporary parenting plan early so a residential schedule governs the household during the waiting period, since temporary orders frequently become the status quo that shapes the final decree.

Washington Residency and Filing Requirements

Washington has no minimum durational residency requirement, making it one of the most accessible states for filing. Under Wash. Rev. Code § 26.09.030, a spouse may file as soon as either party is a Washington resident — or a service member stationed in the state — at the time the petition is filed. There is no 90-day or six-month waiting period to establish residency before filing.

This residency rule is distinct from custody jurisdiction. Even when Washington can grant the divorce, the court can only enter a parenting plan or child support order if it has jurisdiction over the children. Under the Uniform Child Custody Jurisdiction and Enforcement Act at Wash. Rev. Code § 26.27.201, Washington is generally the children's "home state" only if the children have lived in Washington for the six months immediately before the petition, or if Washington was their home state within the last six months and one parent still lives there. If the children have not lived in Washington long enough, the court may dissolve the marriage but defer the parenting plan to the children's home state. Parents who recently moved should confirm jurisdiction before filing to avoid splitting their case across two states.

The Washington Parenting Plan (Not "Custody")

Washington does not use the word "custody" — every divorce with minor children requires a parenting plan that sets a residential schedule, decision-making authority, and dispute resolution procedures. Under Wash. Rev. Code § 26.09.181, each parent must file a proposed plan using the statewide form FL All Family 140, available free at courts.wa.gov, and the final plan cannot be entered until 90 days after filing.

The parenting plan replaces the older "custody" framework with three core components. The residential schedule specifies where the children live each day, including weekday, weekend, holiday, and summer time. Decision-making authority assigns responsibility for major decisions about education, non-emergency health care, and religious upbringing — either jointly or to one parent. Dispute resolution names the method (mediation, arbitration, or court) parents must use before returning to a judge. A plan may also contain restrictions under Wash. Rev. Code § 26.09.191 when there is a history of domestic violence, abuse, neglect, abandonment, or substance abuse — these limitations can override the standard best-interests factors entirely. Parents are free to agree to a 50/50 residential schedule, and since 2008 Washington courts may order substantially equal alternating time whenever it serves the child's best interests, without requiring a prior history of cooperation.

How Washington Courts Decide the Residential Schedule

Washington courts decide the residential schedule using the seven best-interests factors in Wash. Rev. Code § 26.09.187, with the first factor — the strength and stability of each child's relationship with each parent — given the "greatest weight" by statute. The overarching standard from Wash. Rev. Code § 26.09.002 is the best interests of the child, not the preference of either parent.

When the limitations of RCW 26.09.191 do not apply, the seven statutory factors a judge must weigh are: (1) the relative strength, nature, and stability of the child's relationship with each parent — the most heavily weighted factor; (2) any parenting agreements entered knowingly and voluntarily; (3) each parent's past and potential performance of parenting functions, including who handled daily caregiving; (4) the child's emotional needs and developmental level; (5) the child's relationships with siblings, other significant adults, school, and activities; (6) the wishes of the parents and of a sufficiently mature child; and (7) each parent's employment schedule, with accommodations made accordingly. Washington courts do not presume that mothers or fathers are better caregivers — co-parenting arrangements turn on these objective factors. Custody in divorce here favors stability and continuity, which is why the temporary residential schedule set during the 90-day wait often carries forward into the final plan.

Child Support in Washington (2026 Reforms)

Child support in Washington is calculated using the statewide economic table in Wash. Rev. Code § 26.19.020, which under Engrossed House Bill 1014 now covers combined monthly net incomes from $2,200 up to $50,000 effective January 1, 2026. The table sets a presumptive basic support obligation based on the parents' combined net income and the number of children, then apportions it between parents in proportion to their incomes.

The 2026 reforms represent the largest child support overhaul in over a decade. Previously the economic table only addressed combined incomes up to $12,000 per month; EHB 1014 quadrupled that ceiling to $50,000, giving courts presumptive guidance for far more families. For incomes above $50,000, Wash. Rev. Code § 26.19.065 lets a court exceed the presumptive amount only on written findings of fact. The same statute raised the self-support reserve — the income floor a paying parent keeps — from 125% to 180% of the federal poverty level for one person, protecting lower-income parents. A presumptive minimum order of $50 per child per month applies when income falls below that reserve. Washington also became the first state to recognize paid family and medical leave deductions in support calculations. These changes do not update existing orders automatically; a parent must file a formal modification to apply them.

The 90-Day Waiting Period and Divorce Timeline

Washington requires a mandatory 90-day waiting period that begins on the later of the filing date or the service date, and this period cannot be waived or shortened under Wash. Rev. Code § 26.09.030. Even when both spouses fully agree, no final decree or parenting plan can be entered before day 90, as Wash. Rev. Code § 26.09.181 confirms the decree shall be entered "not sooner than ninety days after filing and service."

The 90-day rule is a cooling-off period, not a separation requirement — spouses may continue living together throughout. An uncontested divorce with children where parents agree on the parenting plan and child support often finalizes shortly after the 90-day mark, frequently within four to six months total once paperwork is processed. A contested divorce with children, by contrast, can take twelve months or longer when parents dispute the residential schedule, decision-making, or support, because discovery, mediation, evaluations, and trial scheduling extend the timeline. Many counties require parents to complete a court-approved parenting seminar before finalization. Filing temporary orders early is strategically important: temporary parenting plans and support orders govern the household during the wait and frequently anchor the final outcome.

Modifying a Parenting Plan or Support Order

Washington allows modification of a parenting plan only when there has been a substantial change in circumstances and the change serves the child's best interests, under the demanding standard of Wash. Rev. Code § 26.09.260. Major changes to the residential schedule generally require showing that the current plan is detrimental, while child support is easier to revisit, typically every 24 months or upon a substantial income change.

Washington deliberately makes major parenting-plan changes difficult to protect children's stability. Courts will not reopen the residential schedule for minor disagreements; the moving parent usually must prove the child has been integrated into their home with the other parent's consent, the existing environment is detrimental, or a parent has been held in contempt. Minor adjustments — such as updating the schedule for a child's changing activities — face a lower bar. Child support modification under Wash. Rev. Code § 26.19.065 and related provisions can proceed when income changes substantially, when a child's needs change, or to apply the new 2026 economic table to an older order. Because EHB 1014's expanded $50,000 table and 180% self-support reserve are not retroactive, parents wanting the updated calculations must file a modification rather than waiting for an automatic adjustment.

Relocating With Children After Divorce

Washington's Child Relocation Act requires a parent who has the children a majority of the time to give written notice before moving, generally at least 60 days in advance for moves outside the child's school district, under Wash. Rev. Code § 26.09.430. The non-relocating parent then has 30 days to file a formal objection with the court after receiving notice under Wash. Rev. Code § 26.09.440.

The relocation framework, codified at Wash. Rev. Code § 26.09.405 through 26.09.560, balances a parent's right to move against the child's interest in stability. For a move outside the school district, notice must be served personally or by mail with return receipt at least 60 days before the move; if the relocating parent could not have known in time, notice is due within five days of learning of the move. Notice must include statutorily required language warning that relocation will be permitted unless the other parent files an objection within 30 days. For moves within the same school district, the parent must give reasonable notice, but the other parent cannot block the move — only seek modification under Wash. Rev. Code § 26.09.260. Special protections allow delayed or waived notice when a parent is fleeing domestic violence or facing an immediate safety risk. Failure to give proper notice can result in contempt, sanctions, or fines.
