The Partial Unconditional Lien Waiver is commonly used in Singapore construction projects when partial payments are made for completed work. While Singapore's legal framework differs from US mechanics' lien laws, this document serves as a crucial tool for managing payment risks under the Building and Construction Industry Security of Payment Act (SOPA). It confirms receipt of payment for specific work and waives the contractor's right to make further claims for that portion. This document is typically required before progress payments are released and helps protect owners from potential double payment claims while allowing contractors to maintain their rights for unpaid work.
