I have questions about an “unconditional waiver of lien” form. My parents own a construction LLC business in Oregon. We work in subdivisions for new homes. Recently we received a letter from a contractor and we aren’t sure what it means. Based on what I was able to find, if I’m understanding this correctly, an unconditional waiver of lien means once we sign it, if the contractor fails to pay us for the work we do due to liquidation, bankruptcy or other things, we cannot get paid? I dabbled a little into what a mechanics lien is, if we sign this waiver, we wouldn’t be able to file a mechanics lien?
