A Washington Construction Lien Notice is a legal document used to assert a lien on a property in the state of Washington. This document is used to protect a party’s right to payment for labor, services, or materials provided in connection with an improvement to the property. The document must be filed with the county auditor, along with a copy of the contract, within 90 days of the last day of furnishing services, labor, or materials. There are two types of Washington Construction Lien Notices: Preliminary Notice and Notice of Lien. The Preliminary Notice must be sent to the property owner and all parties involved with the project prior to filing the Notice of Lien. The Notice of Lien must be filed within 90 days of the last day of furnishing services, labor, or materials and must include a detailed description of the work performed, the amount owed, and the parties involved.
