A document giving up lien rights only for the specific payment received, keeping rights for future work.
A partial lien waiver releases lien rights only for work completed and payment received through a specific date or pay period, while preserving lien rights for future work and any disputed amounts. Partial lien waivers are exchanged with each progress payment throughout the project and form a chain of documented payments. They may be conditional (effective only upon payment clearing) or unconditional (effective immediately).
At the end of March, the HVAC contractor signs a partial lien waiver for work completed through March 31 and receives the $60,000 progress payment in exchange.
