Alabama Waiver of Construction Lien is a legal document used in the construction industry that releases a contractor's right to place a lien on a property in Alabama. It is an important document as it protects the property owner from potential claims and provides clarity in the construction process. There are two types of Alabama Waiver of Construction Lien: 1. Conditional Waiver: This type of waiver is typically used when the contractor receives a partial payment or progress payment from the property owner. It waives the contractor's right to place a lien on the property for the specific amount of the payment received. However, the contractor's right to place a lien for any future unpaid amounts remains intact. 2. Unconditional Waiver: This type of waiver is used when the contractor receives full payment for the work done on the construction project. By signing this waiver, the contractor releases their entire right to place a lien on the property, even for any future unpaid amounts. It signifies that the contractor has been paid in full and relinquishes any further claim to the property.
