Affidavit of Surviving Joint Tenant Title-Clearance Requirements in Washington

Requirements one by one

Covered survivorship title

Washington's joint-tenancy statute makes survivorship automatic when the creating written instrument expressly declares a joint tenancy. RCW § 64.28.010 says the property passes to the survivor without the cost or delay of probate, while preserving each tenant's unilateral power to sever before death.

For spouses and registered domestic partners, § 64.28.040 treats a joint-tenancy interest as community property for other purposes but still passes it to the survivor under the joint-tenancy rule. Washington does not supply a separate tenancy-by-the-entirety route: § 11.04.071 abolishes survivorship as an incident of that ownership form.

A different survivorship structure is the community property agreement under § 26.16.120. Both spouses or domestic partners may agree in writing that covered community property will be disposed of at either party's death. The post-death recording statute treats that recorded agreement separately from a joint-tenancy deed.

Instrument, death evidence, and offices

RCW § 82.45.197 gives the statewide post-death route. For joint tenants with right of survivorship and remainder interests, the required documentation is a certified copy of the death certificate. It does not require a separate affidavit signed by the survivor.

If property passes under a community property agreement, the package instead contains two items: a copy of the recorded agreement and a certified copy of the death certificate. The documentation is first provided to the county treasurer and must also be recorded with the county auditor. The statute states no deadline for either step.

Execution formalities

There is no new affidavit to swear, acknowledge, or witness for the ordinary joint-tenancy route. The post-death instrument is the certified death certificate, and § 82.45.197 does not name an affiant or require a survivor's signature.

The community property agreement has its own lifetime formalities. RCW § 26.16.120 requires both spouses or domestic partners to execute a written instrument that is witnessed, acknowledged, and certified in the same manner as a real-estate deed. At death, the recorder receives a copy of that already recorded agreement with the certified death certificate; the survivor does not execute a new statutory affidavit under § 82.45.197(1)(a).

Tax and recording effect

The treasurer step is part of the real estate excise tax documentation. RCW § 82.45.010(3)(a) excludes transfers by gift, devise, or inheritance from the chapter's definition of a taxable sale, and § 82.45.197 identifies the documents used to support that treatment.

Recording does not make the death certificate a deed. Title has already passed under the survivorship incident described in § 64.28.010. RCW § 82.45.197 places the certified death evidence in the county record and supports the tax exclusion, but it does not call the filing a conveyance, guarantee marketable title, or make the creating instrument immune from a severance or validity dispute.

What trips people up

The joint-tenant route is not a lack-of-probate affidavit. RCW § 82.45.197 requires a lack-of-probate affidavit for specified heir and unprobated-will transfers, but subdivision (1)(d) gives joint tenants a different route: a certified death certificate.

A community property agreement needs the recorded agreement too. A death certificate alone is enough for the joint-tenancy route. Under subdivision (1)(a), property passing by community property agreement requires both the recorded agreement copy and the certified death certificate.

Tenancy by the entirety is not a Washington survivorship shortcut. RCW § 11.04.071 abolished survivorship as an incident of that form. The relevant statewide structures are an express joint tenancy or a qualifying community property agreement.

Common questions

Must the survivor sign a Washington affidavit? Not for the statutory joint-tenancy route. RCW § 82.45.197(1)(d) names only a certified copy of the death certificate.

Where does the death certificate go? Provide it to the county treasurer for the inheritance real-estate-excise-tax documentation and record it with the county auditor.

Does the same rule apply to a community property agreement? The offices are the same, but the documents differ. A copy of the recorded agreement accompanies the certified death certificate.

Does recording the death certificate itself transfer title? No. RCW § 64.28.010 describes the joint-tenancy interest as passing to the survivor. Recording documents the death and supports the tax treatment; it is not a new conveyance.
