The Deadline That Kills Your Texas Mechanics’ Lien Claim

Texas mechanics’ liens are one of the most powerful tools available in construction disputes. A properly filed lien clouds the property title, stops closings and refinances, and creates the kind of financial pressure that produces settlements. But the lien is only as good as the notice behind it — and Texas has one of the strictest notice regimes in the country.

Most liens are not lost in court. They are lost before the affidavit is ever filed, because the claimant missed a pre-lien notice deadline — sometimes without knowing it.

The Framework: The 15th Day of the Nth Month

Chapter 53 of the Texas Property Code governs mechanics’ liens. It runs on a “15th day of the Nth month” system, and the critical thing to understand is this: your deadline does not start when you send an invoice or when payment is due. It starts when you performed the work or delivered the materials.

Get that timing wrong and your lien rights for that period are gone.

Original Contractors: The Simpler Path

Original contractors — those with a direct contract with the property owner — have the most straightforward timeline. They generally do not need to send pre-lien notices before filing.

For commercial projects, an original contractor must file its lien affidavit by the 15th day of the fourth month after the month in which the contract was completed, terminated, or abandoned.

For residential projects, the deadline is tighter: the 15th day of the third month. Texas law provides enhanced protections for homeowners, which translates into shorter windows for contractors.

Subcontractors and Suppliers: Where Liens Die

Subcontractors and suppliers — those without a direct contract with the owner — face a fundamentally different system. They must send a pre-lien notice before filing, and that notice must be sent separately for each month in which work was performed and remains unpaid.

This is the step that destroys most lien claims.

On commercial projects, the pre-lien notice must be sent by the 15th day of the third month following each month in which unpaid work was performed. For example, work performed in January requires notice by April 15.

On residential projects, the deadline compresses to the 15th day of the second month following the work month.

Miss the notice for a given month — and you have forfeited your lien rights for that month’s work. Miss enough months, and the entire claim is gone. This happens regularly on long projects where a subcontractor works for several months before a payment dispute surfaces. By the time the dispute is clear, the notice windows for the early months have closed.

The 2022 Overhaul: HB 2237

The most significant change to Texas lien law in decades took effect on January 1, 2022 through House Bill 2237. It applies to all original contracts signed on or after that date. If your project predates January 1, 2022, the prior rules apply.

Key changes from HB 2237 that continue to affect practice:

Delivery methods expanded. Previously, pre-lien notices had to be sent via certified mail or personal delivery. HB 2237 allows any traceable private carrier — FedEx, UPS, or similar — that can confirm proof of receipt. The expanded options are useful, but “traceable” means you need documented confirmation. Sending a notice via a method that cannot confirm delivery still creates exposure.

Design professionals now have lien rights. Licensed architects, engineers, and surveyors who provide designs, drawings, plans, or specifications now have mechanics’ lien rights even when they do not have a direct contract with the property owner. They must comply with the same notice requirements and deadlines as subcontractors, but the protection is now available.

Standardized notice forms. The 2022 overhaul introduced standardized form language for pre-lien notices, which reduced some of the technical deficiency traps that had historically been used to defeat lien claims. It did not eliminate them entirely.

Second-tier subcontractor rules simplified. Before 2022, second-tier subcontractors faced a more complex dual-notice requirement. HB 2237 aligned first-tier and second-tier rules, giving all subcontractors the same basic timeline structure.

The 2025 Fix: SB 929

HB 2237 left an unintentional drafting gap. The statute was ambiguous about whether “15th day of the Nth month” deadlines — which are calendar-date based rather than computed-period based — extended to the next business day when they fell on a Saturday, Sunday, or legal holiday. The prior law was clear that deadlines computed as a number of days (“30 days after X”) extended over weekends, but the fixed-date deadlines were left in a gray zone.

Before SB 929, a cautious claimant had to act before the weekend to be safe. A deadline falling on a Sunday effectively moved the practical deadline to the preceding Friday.

Senate Bill 929, signed by Governor Abbott on May 21, 2025, and effective immediately, closed the gap. Any deadline under Chapter 53 that falls on a Saturday, Sunday, or legal holiday now automatically extends to the next business day. This applies across all lien-related deadlines — pre-lien notices, lien affidavit filings, and enforcement actions.

SB 929 also clarified inception date and priority rules for liens by architects, engineers, surveyors, landscapers, and demolition contractors. For these claimants, the time of inception of the lien is now the date the lien affidavit is recorded — not an earlier date. Priority among competing mechanics’ liens for these claimants is determined by recording date.

The Practical Takeaway

If you are a subcontractor or supplier working on a Texas project, the notice calendar begins the moment you perform unpaid work — not when the payment dispute surfaces. By the time a GC stops returning calls, multiple notice windows may have already closed.

The questions to ask at the start of any project are: What tier am I? Is this commercial or residential? Who gets my pre-lien notices? And is my notice calendar running?

The lien is only powerful if it is valid. Validity starts with the notice.
