General information

Any person who provides labor, professional services, materials, or equipment to improve real property may be able to put a lien on the property. Mechanic's (contractor's) liens provide protection and ensure payment to a person or entity who improved the real property.

Mechanic's liens in Washington are governed by Chapter 60.04 of the Revised Code of Washington (RCW).

Forms and instructions

The Building Industry Association of Washington website has information that helps explain what you need to do to file a lien as well as some sample forms.

The Washington State Bar Association website also has several different blank forms for waiving and/or releasing a lien.
