Which document must a contractor sign to waive a subcontractor's mechanic's lien rights?

The requirement for a contractor to sign a waiver and release is rooted in the mechanics lien laws, which exist to protect the rights of contractors and subcontractors in the event that they are not paid for their work on a property. A waiver and release document explicitly states that the subcontractor waives their right to file a mechanics lien against the property for the payments that have been made.

This waiver often serves as a safeguard for property owners and primary contractors against potential claims from subcontractors for unpaid work. By obtaining a signed waiver and release, the contractor assures that they have made the necessary payments to the subcontractor, thus preventing any disputes or claims for additional payment later on related to that specific work.

In contrast, the other options listed do not serve this purpose. A deed of trust is typically related to securing a loan against property, a notice of intention outlines a party's future plans, and a construction contract establishes the general terms for the construction work but does not specifically address lien waivers. Therefore, the waiver and release are the correct documents needed to effectively void the subcontractor's mechanic's lien rights.
