Washington Eviction Summons is a legal document issued by a court in the state of Washington to a tenant or resident informing them of an impending eviction. The summons outlines the legal reasons why the tenant or resident is being evicted and the legal process required to contest the eviction. The summons also sets a timeline for the tenant or resident to move out. There are two types of Washington Eviction Summons: a Summons for Unlawful Detained and a Summons for Unlawful Retainer and Possession. The Summons for Unlawful Detained is used when the tenant has failed to pay rent or breached the terms of the lease. The Summons for Unlawful Retainer and Possession is used when the tenant has stayed beyond the expiration of the lease or has not vacated after a notice to terminate.
