What is the difference between a conditional and unconditional lien waiver in North Carolina?
Last reviewed July 5, 2026
A conditional lien waiver in North Carolina releases the lien rights only if payment is received. An unconditional lien waiver releases the rights regardless of payment status. This means that once you sign an unconditional waiver, you can't file a lien, even if you haven't been paid yet.
Key points
- Conditional waivers depend on receipt of payment.
- Unconditional waivers release lien rights immediately.
- Use conditional waivers to protect your lien rights until payment.
- Unconditional waivers are riskier if payment is uncertain.
In practice, a conditional lien waiver is often used when you're still waiting for a check to clear. It protects your rights while ensuring the payer knows they can't face a lien if they pay up. An unconditional waiver is riskier because it gives up your rights entirely, even if payment doesn't come through as expected.
