RCW 60.04.051: Property subject to lien.

The lot, tract, or parcel of land which is improved is subject to a lien to the extent of the interest of the owner at whose instance, directly or through a common law or construction agent the labor, professional services, equipment, or materials were furnished, as the court deems appropriate for satisfaction of the lien. If, for any reason, the title or interest in the land upon which the improvement is situated cannot be subjected to the lien, the court in order to satisfy the lien may order the sale and removal of the improvement from the land which is subject to the lien.
