Wash. Rev. Code § 59.12 § 59.12.140
Proof in forcible entry and detainer.
Operative Text
On the trial of any proceeding for any forcible entry or forcible detainer the plaintiff shall only be required to show, in addition to a forcible entry complained of, that he or she was peaceably in the actual possession at the time of the forcible entry; or, in addition to a forcible detainer complained of, that he or she was entitled to the possession at the time of the forcible detainer.
Washington's Wash. Rev. Code § 59.12.010 et seq. § 59.12.140 sets out what a plaintiff must prove at trial in a forcible entry or forcible detainer case. For a forcible entry claim, the plaintiff need only show that they were peacefully in actual possession of the property when the entry occurred. For a forcible detainer claim, the plaintiff need only show that they were entitled to possession at the time of the unlawful detainer — no additional elements are required beyond the wrongful act itself.

Under Wash. Rev. Code § 59.12.010 et seq. § 59.12.140, a property owner or manager who brings a forcible entry or detainer action in Washington is generally expected to be able to document their right to possession or their peaceful actual possession at the relevant time. Compliant operators typically maintain clear records of lease agreements, ownership documents, and any notices served, as these can establish entitlement to possession. Understanding the limited but specific proof requirements of this statute helps operators prepare appropriately for any court proceeding involving disputed possession.

Wash. Rev. Code § 59.12.010 et seq. § 59.12.140 defines the evidentiary threshold a plaintiff must meet in a forcible entry or detainer proceeding, which can be relevant to tenants who find themselves named in such an action or who are themselves bringing a claim. A tenant who was peaceably in actual possession of a property may have standing to raise a forcible entry claim if that possession was disrupted by force. Tenants facing or considering such proceedings may benefit from consulting a tenant-rights organization or legal aid provider familiar with Washington's unlawful detainer statutes to understand how this proof standard applies to their circumstances.
