Rules

Has a Certificate of Completion been issued for your contract?

A starts both the lien and clocks.

Have you filed a claim of lien?

A can be filed any time once work begins, even before completion. What matters is filing no later than 45 days after the clock starts.

Answer the questions above and your deadlines will appear here, each tied to the date that triggers it.

These dates are general information, not legal advice. Edge cases (multiple certificates, abandonment, phased projects) can change the math. When the tracker launches, every deadline here gets watched automatically. Join the waitlist.
