- Mechanic's Lien
- A statutory security interest placed on a property by a contractor, subcontractor, or supplier who has not been paid for labor or materials provided to improve that property.
- Lien Waiver
- A document in which a claimant voluntarily relinquishes their right to file a mechanic's lien, typically in exchange for payment.
- Conditional Lien Waiver
- A waiver that becomes effective only upon receipt and clearance of a specific payment β it does not extinguish lien rights until the payment actually clears.
- Unconditional Lien Waiver
- A waiver that takes immediate effect upon signing, regardless of whether the associated payment has actually cleared β the highest-risk waiver for the signing party.
- Progress Payment Release
- A lien release covering work performed and paid for through a specific date or draw, while preserving lien rights for future unpaid work.
- Final Release
- A lien release covering all work performed on a project through completion, extinguishing all remaining lien rights of the signing party.
- Claimant
- The subcontractor, supplier, or laborer who holds or has the right to file a mechanic's lien against the property.
- Through Date
- The specific calendar date through which the lien waiver covers work performed β work completed after this date is not released.
- Statutory Lien Waiver Form
- A prescribed lien waiver form mandated by state law in jurisdictions such as California and Texas β using a non-statutory form in these states can render the waiver void.
- Retainage
- A percentage of each progress payment β typically 5β10% β withheld by the owner or GC until project completion, which is usually addressed in a separate final lien release.
- Bond Claim
- A claim against a payment bond posted by the GC or owner on a bonded project, which substitutes for a mechanic's lien on public works projects where property liens are unavailable.
