What is the difference between a conditional and unconditional lien waiver in Ohio?
Last reviewed July 5, 2026
In Ohio, a conditional lien waiver is effective only upon payment being made. An unconditional lien waiver is effective immediately, regardless of whether payment has been received. Both types are used to release lien rights, but the conditional waiver protects the contractor until payment is confirmed.
Key points
- Conditional waivers require payment to be effective.
- Unconditional waivers take effect immediately.
- Use conditional waivers when payment is pending.
- Unconditional waivers are riskier for contractors.
Understanding the difference between these waivers is key for managing payment risks. Conditional waivers are often used when a check's in the mail or payment is expected soon. Unconditional waivers should be used with caution, as they release your right to file a lien regardless of whether you receive payment later.
