As noted above, RCW 60.04 contains the rules and procedures for recording liens. Typically when the owner is paying for work in installments, such as progress payments, contractors give a partial release of the lien with each payment. This reduces the amount of the lien by the amount of the payment received. The mechanics' lien statutes are very strict and procedure-oriented. If you don't do each step exactly right, you may not be able to enforce the lien. You should definitely consult a lawyer knowledgable in construction and real estate who can explain your rights and assist you in recording the proper notices and releases.
