RCW 60.04.071: Release of lien rights.

Upon payment and acceptance of the amount due to the lien claimant and upon demand of the owner or the person making payment, the lien claimant shall immediately prepare and execute a release of all lien rights for which payment has been made, and deliver the release to the person making payment. In any suit to compel deliverance of the release thereafter in which the court determines the delay was unjustified, the court shall, in addition to ordering the deliverance of the release, award the costs of the action including reasonable attorneys' fees and any damages.
