I'm afraid this is a little outside of our wheelhouse at the Construction Legal Center. While we regularly discuss mechanics liens and even provide free forms for mechanics liens in every state, a mechanics lien secures the right to payment for construction work performed and unpaid. Other liens or encumbrances may be available for lenders in Washington, of course. This resource from RocketLawyer might be useful: How to Place a Lien on a House or Other Personal Property. Further, other online resources such as Avvo provide a forum where individuals can ask legal questions on a variety of subjects and receive answers from attorneys - beyond construction law.
