Surviving Spouse Rights in Washington State: Inheritance, Probate, and Taxes

If your spouse has died in Washington, you already own half of everything the two of you built together, and state law puts you first in line to receive the rest. Surviving spouse rights in Washington State flow from one central fact: Washington is a community property state, and that classification shapes what you inherit, what you can claim during probate, and what taxes you’ll owe. This article walks through what belongs to you outright, what the law gives you from your spouse’s share, and the protections and benefits available while the estate is settled.

What You Already Own vs. What Passes Through the Estate

Almost everything acquired during the marriage is community property in Washington, meaning each spouse owns an undivided half regardless of whose paycheck funded it or whose name is on the title.¹ Wages, the house bought with marital earnings, investment accounts, and debts taken on during the marriage all sit in the community pot. The day your spouse dies, your half is already yours. It isn’t an inheritance, and it doesn’t pass through the will. Only your spouse’s half is up for distribution.

Separate property is different. Anything your spouse owned before the wedding, or received during the marriage as a personal gift or inheritance, stayed theirs alone.² Your spouse could leave separate property to anyone they chose. You have no guaranteed share of it unless the will names you or intestate succession kicks in.

When community money was used to maintain or improve a separate asset (for example, paying down the mortgage on a house your spouse owned before you married), the community can have a reimbursement claim against that property. The accounting can get complicated, and good records of how funds moved between accounts matter if a dispute comes up.

What You Inherit If There Is No Will

When a spouse dies without a will, Washington’s intestate succession statute decides who gets what.³ You receive the decedent’s entire half of community property, which gives you full ownership of all community assets. That result holds no matter how many children, parents, or siblings your spouse had.

Separate property is split differently depending on who else survived:³

If your spouse left children or grandchildren, you receive one-half of the separate estate and the descendants split the other half.
If there are no descendants but a parent or sibling survives, you receive three-quarters, and the remaining quarter goes to the parents or their descendants.
If there are no descendants, parents, or siblings, you inherit all of the separate property.

These shares are fixed by statute. They don’t account for the length of the marriage, the size of the estate, or anyone’s financial need. For most couples whose wealth is primarily community property, the surviving spouse ends up with everything under intestacy. The separate-property split matters most in second marriages where one spouse brought significant assets into the relationship.

What You Can Claim If the Will Cuts You Out

Washington does not have an elective share statute. That’s the tool many other states give a surviving spouse to override an unfavorable will and claim a percentage of the estate. Washington relies instead on the community property system as the main safeguard: because you already own half of all community property, no will can take that away.⁴ Only your spouse’s half can be given away.

A will can, however, leave all of your spouse’s separate property to someone else. If your spouse accumulated substantial wealth before the marriage or received large inheritances, you have no statutory right to claim any of it. Two Washington-specific protections soften that result.

Award in Lieu of Homestead

You can petition the court for an award in lieu of homestead. The base amount is at least $125,000 and is adjusted annually for inflation using the Seattle-area consumer price index.⁵ This award comes off the top of the estate and can override what the will says. It exists specifically so a surviving spouse isn’t left with nothing while probate runs its course.

Family Allowance

If the homestead award isn’t enough, the court can grant a family allowance for the ongoing support of you and any minor children during probate.⁶ The allowance covers day-to-day expenses like groceries, utilities, and housing so you don’t have to drain personal savings waiting for the estate to close. Both the homestead award and the family allowance are priority claims, meaning they are paid before general creditors collect. You activate either one by filing a petition in the probate case.

Running the Estate

Someone has to administer the estate through probate, and Washington gives the surviving spouse first priority to serve as personal representative.⁷ If you’re willing and competent, you can petition the court for appointment, which gives you authority to gather assets, pay debts, and distribute property. Children, parents, and siblings fall further down the priority list in that order.

Serving in that role means you control the timeline and the administrative decisions that affect your financial outcome. You sign legal documents on behalf of the estate, access bank records, and manage real property. If you don’t want the job, you can nominate someone else, though that person will generally need court approval. The appointment requires filing a petition and requesting letters testamentary (if there’s a will) or letters of administration (if there isn’t).

Small Estate Affidavit

Not every estate needs formal probate. If the probate estate is worth $100,000 or less (not counting your community property share), you can claim assets through a small estate affidavit instead of going through the full court process.⁸ The affidavit can be presented to banks, employers, or anyone holding the decedent’s property, and they are required to release the assets.

You must wait at least 40 days after the death, and all of the decedent’s debts (including funeral expenses) must already be paid or accounted for. The affidavit requires a description of the property being claimed, written notice to all other potential heirs, and a copy mailed to the Washington Department of Social and Health Services.⁸ No court appearance is needed.

Life Insurance, Retirement Accounts, and Other Non-Probate Assets

Life insurance payouts, retirement accounts, payable-on-death bank accounts, and jointly held property with survivorship rights all transfer directly to the named beneficiary without passing through probate. These can be the largest portion of an estate, and they follow the beneficiary form on file rather than the will.

Washington’s community property rules still apply. Your half of community property is confirmed to you, and only the decedent’s half can be directed elsewhere.⁴ If your spouse named someone else as the beneficiary on a retirement account funded entirely with community earnings, you still have a claim to your half of those funds.

Federal law adds another layer for employer-sponsored retirement plans. Under ERISA, a married participant’s spouse is automatically the beneficiary of the plan unless the spouse signs a written waiver.⁹ That waiver has to be notarized or witnessed by a plan representative. No one can quietly redirect a 401(k) away from a spouse without that consent.

A note on movers: if you and your spouse acquired assets in a separate-property state before relocating to Washington, the state’s quasi-community property rules can treat those assets as if they had been community property all along, giving you the same half-interest.¹⁰

Tax Benefits You Shouldn’t Miss

Double Step-Up in Cost Basis

This is one of the most valuable and least understood benefits of being a surviving spouse in a community property state. Under federal tax law, when one spouse dies, the cost basis of the survivor’s half of community property resets to fair market value along with the decedent’s half.¹¹ In separate-property states, only the decedent’s half gets this adjustment.

The dollar impact can be dramatic. Say the two of you bought your home decades ago for $150,000 and it’s now worth $800,000. You get a full basis reset to $800,000. Selling the next day would trigger zero capital gains tax. In a separate-property state, only half would reset, leaving potentially hundreds of thousands of dollars in taxable gain on your half.

Filing Status

In the year your spouse dies, you can still file a joint federal return for that tax year, preserving the wider tax brackets and higher standard deduction.¹² For the two following tax years, you may qualify for Qualifying Surviving Spouse status if you have a dependent child, which continues the joint-return brackets. After that, you file as single or head of household.

Washington Estate Tax

Washington is one of roughly a dozen states with its own estate tax, and its threshold is far lower than the federal one. For 2026, the filing threshold and exclusion amount is $3,076,000.¹³ Estates above that face graduated rates starting at 10% and climbing to 35% on amounts over $9 million.¹⁴ Property left directly to you qualifies for the marital deduction and won’t trigger state estate tax at the first death, but it will be counted in your estate later. Couples with combined assets approaching $3 million need to plan for this, because the Washington threshold catches estates that sail comfortably under the federal exemption.

Federal Estate Tax and the Portability Election

The federal estate tax exemption for 2026 is $15,000,000 per individual, a figure increased by the One, Big, Beautiful Bill Act signed in July 2025.¹⁵ Most married couples won’t owe federal estate tax. Even so, consider filing Form 706 within nine months of the death (a six-month extension is available) to elect portability of your spouse’s unused federal exclusion.¹⁶ Portability can let you shelter up to $30 million in combined exemptions. Asset growth, future inheritance, or changes in tax law could make that election valuable decades later. Miss the filing deadline and the option is gone permanently.

Social Security Survivor Benefits

You can begin collecting Social Security survivor benefits as early as age 60, or age 50 if you have a qualifying disability. If you are caring for the deceased’s child who is under 16 or disabled, you can collect at any age, with no minimum. Benefits claimed before full retirement age are reduced, so timing involves real tradeoffs. A surviving former spouse can also qualify if the marriage lasted at least ten years.¹⁷

Survivor benefits are federal and work the same way in every state. One Washington wrinkle is worth noting: the deceased’s earnings record (which sets the benefit amount) was built on community income. If you stayed home to raise children, you still benefit from your spouse’s full earnings history, because those wages belonged equally to both of you under Washington law.
