Which document serves to affirm that all required payments have been made for construction services?

• A. Change order
• B. Notice of completion
• C. Conditional lien waiver
• D. Building permit

Answer: (C)

The document that serves to affirm that all required payments have been made for construction services is the conditional lien waiver. This document is used in the construction industry to waive the right to file a lien on a property under certain conditions, often contingent upon receipt of payment. By signing a conditional lien waiver, contractors and subcontractors acknowledge that they have received payment for their work, but only to a certain extent or upon certain conditions being met. This offers a level of security to property owners and ensures that the contractor will not later seek to place a lien on the property for unpaid work.

The other choices represent different types of documents that serve distinct purposes within construction but do not specifically confirm that all payments have been made. A change order modifies the original construction contract, a notice of completion marks the end of construction work and serves to start the period for filing liens, and a building permit signifies legal permission to begin construction but does not address payment status. Thus, the conditional lien waiver is the most appropriate document for affirming that all required payments have taken place.
