Lien waivers work to protect everyone involved in a construction project from a mechanics lien. If a stakeholder on a project is not paid, they can place a lien on the property for non-payment. Lien waivers act as a receipt in the construction industry.

What rights are waived with a California lien waiver?

Essentially, a lien waiver waives the right to sue a payor for non-payment. The lien waiver acts as a receipt of payment so a lien cannot be placed on a property for the non-payment of construction costs.

What is an unconditional lien waiver form?

In California, unconditional lien waiver forms are used when payment for supplies or work has been made. You are waiving your right to place a lien on a property for non-payment because payment has been made. It’s important to note that unconditional lien waiver forms do not protect against insufficient funds (a bounced check). So you should only sign an unconditional lien waiver if funds are in your account.
