Common Mistakes That Invalidate Liens
By Caitlin S. Truelove
Attorney at Law

Mechanics' liens serve as a powerful tool for contractors, subcontractors, and suppliers to secure payment for labor and materials provided on a construction project. However, North Carolina law imposes strict procedural requirements for perfecting a lien, and even minor mistakes can render a lien unenforceable.
This article explores common mistakes that our firm as seen that can invalidate a lien in North Carolina and provides guidance on how to avoid them.
- Missing the Deadline to File the Lien
One of the most critical mistakes is failing to file the lien within the required statutory timeframe. North Carolina law sets strict deadlines:
- A Claim of Lien on Real Property must be filed within 120 days from the last date the lien claimant furnished labor or materials to the project.
- A Lien on Funds must be served before the party holding the funds disburses them.
- A lawsuit to enforce the lien must be filed within 180 days from the last furnishing date.
Failing to meet these deadlines can result in the lien being invalid and unenforceable.
- Incorrectly Identifying the Property or Owner
A lien must accurately identify the real property being improved and the property owner. Common errors include:
- Using an incorrect legal description of the property.
- Listing the wrong owner due to a failure to verify property records.
To avoid this, lien claimants should conduct a title search or consult county property records before filing.
- Overstating the Lien Amount
A lien must reflect only the amount legitimately owed for labor or materials provided. Overstating the lien, whether intentionally or by mistake, can lead to challenges, including:
- Legal claims for fraudulent filing.
- Possible invalidation of the entire lien.
To prevent this, claimants should ensure they document all costs accurately and avoid including unapproved or speculative amounts.
Perfecting a lien in North Carolina requires strict adherence to statutory requirements. Missing deadlines, providing incorrect property information, or overstating amounts can all render a lien invalid. Contractors, subcontractors, and suppliers should carefully follow the legal process to protect their lien rights.
