An Unconditional Partial Lien Waiver is a legal document used in Singapore's construction industry that waives a contractor's or subcontractor's right to file a lien for work completed and paid for up to a specific date or payment amount. Under Singapore law, particularly the Building and Construction Industry Security of Payment Act (SOPA), this document provides assurance to property owners that they won't face double payment claims for work already compensated, while allowing contractors to maintain lien rights for unpaid work or future work.

What is a Unconditional Partial Lien Waiver?

The Unconditional Partial Lien Waiver is a crucial document in Singapore's construction industry that helps manage payment risks and project completion certainty. It is typically used when a contractor or subcontractor receives partial payment for work completed on a project and needs to formally acknowledge receipt of payment while waiving their right to file a lien for that specific portion of work. The document must comply with Singapore's Building and Construction Industry Security of Payment Act (SOPA) and includes specific details about the project, payment amount, and work completed. It's particularly important in large construction projects where multiple payment phases are involved and serves as protection for both the paying party and the contractor.
