Wash. Rev. Code § 60.04.161
Any owner of real property subject to a recorded claim of lien under this chapter, or contractor, subcontractor, lender, or lien claimant who disputes the correctness or validity of the claim of lien may record, either before or after the commencement of an action to enforce the lien, in the office of the county recorder or auditor in the county where the claim of lien was recorded, a bond issued by a surety company authorized to issue surety bonds in the state. The surety shall be listed in the latest federal department of the treasury list of surety companies acceptable on federal bonds, published in the Federal Register, as authorized to issue bonds on United States government projects with an underwriting limitation, including applicable reinsurance, equal to or greater than the amount of the bond to be recorded. The bond shall contain a description of the claim of lien and real property involved, and be in an amount equal to the greater of five thousand dollars or two times the amount of the lien claimed if it is ten thousand dollars or less, and in an amount equal to or greater than one and one-half times the amount of the lien if it is in excess of ten thousand dollars. If the claim of lien affects more than one parcel of real property and is segregated to each parcel, the bond may be segregated the same as in the claim of lien. A separate bond shall be required for each claim of lien made by separate claimants. However, a single bond may be used to guarantee payment of amounts claimed by more than one claim of lien by a single claimant so long as the amount of the bond meets the requirements of this section as applied to the aggregate sum of all claims by such claimant. The condition of the bond shall be to guarantee payment of any judgment upon the lien in favor of the lien claimant entered in any action to recover the amount claimed in a claim of lien, or on the claim asserted in the claim of lien. The effect of recording a bond shall be to release the real property described in the notice of claim of lien from the lien and any action brought to recover the amount claimed. Unless otherwise prohibited by law, if no action is commenced to recover on a lien within the time specified in RCW 60.04.141, the surety shall be discharged from liability under the bond. If an action is timely commenced, then on payment of any judgment entered in the action or on payment of the full amount of the bond to the holder of the judgment, whichever is less, the surety shall be discharged from liability under the bond.
Nothing in this section shall in any way prohibit or limit the use of other methods, devised by the affected parties to secure the obligation underlying a claim of lien and to obtain a release of real property from a claim of lien.
