Common questions
What does this calculator estimate?
It estimates construction lien dates under the selected state’s rules from the dates and contract relationship you provide. It does not determine lien eligibility or whether notice was validly served.
When does a Notice of Contest start the shorter period?
The estimate uses the date the notice was served on the lienor. Recording the notice is a separate event.
Can other events change these dates?
Yes. Final payment, contract termination, court proceedings, amended claims, local holidays and emergency closures can change the applicable dates.
Can I use it without an account?
Yes. The web calculator requires no account. The standalone mobile apps are designed to save jobs on your device.
