Check the notice deadline
for an unpaid work month.

For subcontractors and material suppliers on eligible Texas private projects. Free to use; no account required.

The work month matters—not the late invoice date.

If you are a subcontractor or supplier, check notice timing for each unpaid work month. Confirm project eligibility, then enter a work or delivery date in the unpaid month. This tool shows only a monthly notice estimate; it does not calculate affidavit or suit deadlines. Separate legal review may be needed.

Your project

Residential covers construction or repair of an owner's residence, including improvements appurtenant to it, under a contract with the owner. A qualifying residence is a house with 1–4 units or an individual condo or co-op unit, owned by one or more adults and used or intended as a dwelling by an owner. Homestead requirements are separate and not checked here. Unsure? Ask a Texas construction attorney before choosing.

Monthly notice estimate

Your notice estimate will appear here.

Complete the project questions, then check the work month. The estimate does not decide whether a lien is valid.

Monthly notice estimates only. This tool does not calculate affidavit or suit dates. Public projects, payment bonds, homestead projects, retainage and specially fabricated materials are outside this tool. Estimates only, not legal advice.

Why do you ask about the original contract?+
The engine does not support original contracts entered into before January 1, 2022. A later work date alone does not establish whether the contract is supported.
