What is a Lien Waiver?
A lien waiver is a legal document in which a contractor, subcontractor, or supplier relinquishes the right to place a lien on a property once payment is received.
Why Lien Waivers Matter in Real Estate
In Canadian construction and real estate, lien waivers protect property owners from claims for unpaid work or materials.
Key points:
- Issued after payment for services or supplies
- Helps ensure clear title on completion
- Often required by lenders before disbursing funds
Understanding lien waivers helps owners and developers manage construction risk and secure financing.
