Washington is a community property state under RCW 26.16. All property acquired during marriage is community property — equally owned 50/50 by both spouses regardless of who earned the money or whose name is on the title. Separate property (inherited during marriage, acquired before marriage) remains separate only if not commingled with community funds. King County Superior Court (Family Law Division, 516 Third Ave., Seattle, WA 98104) handles divorce. Both spouses must sign the deed for sale of community real property (RCW 26.16.030). Washington REET (1.10%–3.0%) applies to every sale — including divorce-related sales. Washington has no mandatory separation period before filing.
Washington Community Property: How Seattle Divorce Property Division Works
Washington is one of nine community property states. RCW 26.16 governs the community property system in Washington:
Community property: All property acquired during the marriage, regardless of whose name is on the title or who earned the income. A Seattle home purchased during the marriage with one spouse’s salary is community property even if titled in only one spouse’s name.
Separate property in Washington:
- Property acquired before the marriage
- Property acquired during marriage by gift or inheritance to one spouse alone — but ONLY if not commingled with community funds
- Property excluded by prenuptial or postnuptial agreement
The commingling trap. Washington courts apply strict commingling analysis. If separate property funds (e.g., an inheritance) are deposited into a joint account and used for community purposes, the separate property “transmutes” into community property — and tracing it back to separate status requires forensic accounting. For Seattle homes purchased with a mix of separate and community funds, both spouses should consult a Washington family law attorney before agreeing to any division.
The “just and equitable” standard in Washington (RCW 26.09.080). Despite being a community property state, Washington’s divorce courts divide property “in a just and equitable manner” considering all relevant factors — not necessarily 50/50. Washington courts can award one spouse more than 50% of the marital estate if circumstances warrant (e.g., one spouse is the primary caregiver of minor children and needs the family home; one spouse created waste of marital assets). Washington does NOT use marital misconduct as a property division factor — unlike North Carolina, which considers adultery, substance abuse, and abandonment.
King County Superior Court: How Seattle Divorce Proceeds
King County Superior Court Family Law Division is at 516 Third Avenue, Seattle, WA 98104. Seattle divorces do NOT require a mandatory separation period — the dissolution can be filed immediately. Washington’s mandatory 90-day waiting period (from filing to final decree) applies — the court cannot enter a final divorce decree less than 90 days after filing.
Temporary Orders in Seattle Divorce: During pending divorce proceedings, King County Superior Court can enter Temporary Orders governing: use of the marital home, mortgage payment obligations, insurance maintenance requirements, and temporary maintenance (spousal support). Temporary Orders are critical to prevent one spouse from allowing the Seattle home’s condition to deteriorate, failing to pay the mortgage, or letting insurance lapse.
Washington Community Waste Doctrine. If one spouse deliberately dissipates or wastes community assets during the divorce (e.g., allows a rental property to fall into disrepair, fails to pay property taxes, lets insurance lapse), the court can account for the waste in the final property division — awarding the non-wasting spouse a larger share of remaining assets. This incentivizes both spouses to maintain community property during the divorce proceedings.
Both Spouses Must Sign — Washington’s Community Property Title Rule
RCW 26.16.030 requires the joinder of both spouses for conveyance of community real property. Washington title insurance companies will not insure a transaction where the grantor is one spouse and the other spouse has not signed the deed, unless:
- A court order establishes the property as separate property
- A court order specifically authorizes the sale by one spouse alone
- A power of attorney (Washington-compliant) authorizes one spouse to sign for the other
In practice: both spouses must sign the deed. If one spouse refuses, the court can order the sale and appoint a commissioner (referee) to sign on behalf of the refusing spouse.
Three Options for the Seattle Marital Home in Divorce
Option 1: Sell and Split Proceeds (Most Common)
Both spouses agree to sell. Washington REET (1.10%–3.0%) is paid by the seller — for a $750,000 Seattle home, that’s $8,655 in REET plus commission (5%–6% = $37,500–$45,000). Net proceeds are divided per the divorce agreement or court order. A cash sale eliminates commission — the only unavoidable cost is REET and basic closing costs.
Washington CGET consideration: If the couple qualifies for the federal primary residence exclusion ($500,000 married), the sale of the marital home typically produces no CGET. If one spouse is awarded the home and later sells as a single person, only the $250,000 single-filer exclusion applies — potentially creating CGET on the gain above $250,000.
Option 2: One Spouse Buys Out the Other
The keeping spouse refinances in their name alone (removing the departing spouse from the mortgage) and pays the other their share of equity. King County Superior Court can order a buyout if the couple cannot agree. The buyout payment is not subject to REET — REET applies only to third-party sales, not spousal buyouts (they are excluded from REET under RCW 82.45.010(6)(a)).
Option 3: Deferred Sale (Bird’s Nest)
Court orders the house to remain for use by the custodial parent and children until a triggering event (youngest child turns 18, remarriage, sale). During the deferred period: the non-occupying spouse retains a community property interest; mortgage, taxes, insurance, and REET accrue until sale. Seattle’s rapidly appreciating market makes deferred sales financially complex — each year of deferral may push the eventual sale price into a higher REET bracket.
