Washington intestacy laws decide who inherits when someone dies without a valid will, or without a will that covers every asset. For families in Snohomish County and King County, that default roadmap can surprise surviving spouses, adult children, and parents who assumed everything would simply pass to the person they had in mind. Understanding how Washington divides community property and separate property after an intestate death gives you real control over whether to leave those defaults in place or replace them with a plan of your own.
At Bountiful Law, we help individuals and families across Snohomish County and King County, Washington, understand how intestacy, probate, and estate planning tools fit together so you can move forward with confidence. This guide explains what Washington intestacy laws actually do, how shares are calculated when a spouse or domestic partner survives, and the planning mistakes that leave people stuck with an inheritance pattern they never wanted.
What Washington Intestacy Laws Actually Do
Intestacy is the legal status of dying without a will that disposes of your probate estate. Washington Revised Code of Washington (RCW) 11.04.015 sets the distribution order for the net estate of a person dying intestate, or for any portion of the estate that the will does not cover. The statute first accounts for a surviving spouse or state registered domestic partner, then distributes whatever remains to issue, parents, grandparents, or their descendants in a fixed sequence. Those rules apply whether the person lived in Lynnwood, Everett, Seattle, Bellevue, or elsewhere in Snohomish County or King County, because they are statewide statutes, not local ordinances.
Community Property Versus Separate Property
Washington is a community-property state. Under RCW 26.16.030, property acquired after marriage or after registration of a state registered domestic partnership by either spouse or domestic partner is generally community property, subject to the separate-property definitions in RCW 26.16.010 and 26.16.020. That classification matters at death because RCW 11.04.015 treats the decedent’s share of the net community estate differently from the net separate estate. The surviving spouse or domestic partner receives all of the decedent’s share of the net community estate, then a fractional share of the separate estate that depends on who else survives.
The Surviving Spouse or Domestic Partner Share
RCW 11.04.015(1) is specific. The surviving spouse or state registered domestic partner receives all of the decedent’s share of the net community estate. For the net separate estate, that survivor receives one-half if the intestate is survived by issue; three-quarters if there is no surviving issue but a parent or issue of a parent survives; or all of the net separate estate if there is no surviving issue, parent, or issue of a parent. Families often focus only on the house or the bank accounts and miss how that community-versus-separate split changes the math for children from a prior relationship.
Who Takes When There Is No Surviving Spouse
If there is no surviving spouse or state registered domestic partner, or after that survivor’s share is set aside, RCW 11.04.015(2) sends the remaining estate to the intestate’s issue; if none, to surviving parents; if none, to issue of the parents; then to grandparents and their issue in the order the statute describes. When takers are in unequal degrees of kinship, more remote descendants take by representation as defined in Title 11. Half-blood relatives generally inherit the same share as whole-blood relatives under RCW 11.04.035, with a limited ancestral-property exception.
How an Intestate Estate Is Actually Handled in Washington
Intestacy answers who inherits. It does not erase the need for someone to collect assets, pay enforceable obligations, and transfer title. In Snohomish County and King County, that work usually runs through the probate court process for assets that require a personal representative. Knowing the distribution statute early helps the family understand what a petition is asking the court to authorize and who has standing to object.
Identify Which Assets Are Even Subject to Intestacy
Not every account follows the will or the intestacy statute. Life insurance proceeds, retirement accounts, payable-on-death bank accounts, and many transfer-on-death registrations pass by beneficiary designation when the designation is valid. Joint tenancy with right of survivorship property can also pass outside the probate estate. Washington intestacy laws still matter for the leftover probate assets, and for any asset whose beneficiary designation failed, lapsed, or named the estate. Families in King County and Snohomish County regularly discover that the house, a sole-owner brokerage account, or a vehicle title is the piece that actually triggers intestacy analysis.
Map Heirs Before Filing
Before a personal representative can distribute under RCW 11.04.015, the family needs a clear picture of the surviving spouse or domestic partner, the decedent’s issue, and whether parents or more remote relatives are in the line of succession. Prior marriages, adopted children, and half-siblings change the chart. Accurate heirship mapping prevents a petition from naming the wrong distributees and reduces later disputes among people who believed they were entitled to equal shares when the statute says otherwise.
Distinguish Probate Administration From the Inheritance Formula
Opening a probate case authorizes someone to gather assets and settle the estate. The intestacy statute tells that person how to divide what remains after lawful obligations. Those are related but separate ideas. A person who dies without a will still may need a court-appointed personal representative, bond questions, notices to heirs, and an inventory. Understanding RCW 11.04.015 helps the personal representative explain to heirs why a spouse receives the community share while children receive only part of the separate estate, or why parents take when there are no issue.
Use Estate Planning Documents When You Want a Different Result
If the intestacy pattern does not match your wishes, Washington law lets you change the outcome while you are alive and competent. A will that meets RCW 11.12.020’s writing, signature, and witness requirements can redirect probate assets. Beneficiary designations, community property agreements, and trusts can redirect other assets. For residents of Snohomish County and King County, the practical question is whether today’s default under RCW 11.04.015 is acceptable, or whether a written plan should replace it.
What Commonly Derails Families After an Intestate Death
Most intestacy problems are not mysteries about the statute’s wording. They come from missing documents, wrong assumptions about community property, overlooked beneficiary forms, and delay while titles and accounts sit unresolved. The same pattern appears in both Snohomish County and King County estates: people thought a conversation or a draft will was enough, then discovered the law filled the gap with a formula nobody reviewed.
Assuming a Surviving Spouse Automatically Inherits Everything
RCW 11.04.015 does give the surviving spouse or domestic partner all of the decedent’s share of the net community estate, but the separate-estate share is often only one-half when issue survive. That distinction is easy to miss when a family home was brought into the marriage as separate property, or when a brokerage account traces to an inheritance. Treating every asset as if it belongs solely to the survivor can create conflict with adult children who have a statutory claim to part of the separate estate.
Leaving Beneficiary Designations Stale or Blank
Intestacy becomes the backup plan for assets that should have passed by contract. An outdated spouse named on a retirement account, a blank payable-on-death line, or a life insurance policy that lists the estate can drag nonprobate assets into the probate conversation. Reviewing designations after marriage, divorce, the birth of a child, or a move into Snohomish County or King County is one of the simplest ways to keep Washington intestacy laws from controlling accounts you never intended to put through court.
Waiting Until After a Crisis to Compare Defaults Against Your Goals
People often postpone wills because they assume Washington’s default is close enough. Sometimes it is. Sometimes it sends property to parents instead of a long-term partner who was never a spouse or state registered domestic partner, or it splits separate property with children from a prior relationship in a way that leaves the survivor house-rich and cash-poor. Comparing RCW 11.04.015 against your actual family chart while everyone is healthy is far easier than reconstructing intentions after a death in Everett, Seattle, or elsewhere in the two counties.
Final Thoughts
Washington intestacy laws under RCW 11.04.015 provide a clear, statewide formula for who inherits when there is no controlling will. Community property rules in RCW 26.16.030 help explain why a surviving spouse or domestic partner often receives the decedent’s community share, while separate property may be shared with issue or other relatives. Half-blood inheritance rules in RCW 11.04.035 and will-execution requirements in RCW 11.12.020 complete the picture of how Washington treats heirs and how you can replace the default with a written plan.
