There are two types of Montana Waiver of Lien Claim by Subcontractor: 1. Conditional Waiver: A conditional waiver is used when a subcontractor acknowledges receiving payment but states that it is conditional upon the payment being cleared and successfully deposited. This type of waiver is commonly used to ensure that funds are transmitted before removing the lien rights. 2. Unconditional Waiver: An unconditional waiver is used when a subcontractor certifies that they have received payment for furnished labor, materials, or services in a construction project. By signing an unconditional waiver, the subcontractor relinquishes their right to file a lien against the property as payment has already been received. It is vital for subcontractors to carefully review and understand the terms and conditions of the waiver before signing. It is recommended to consult with a construction attorney to ensure compliance with Montana's lien laws and secure their rights to payment.
