Texas Mechanic's and Materialman's Liens: Deadlines, Notice Requirements, and How to Perfect Your Lien

By Hank FasthoffJuly 5, 2026

If you furnished labor or materials on a Texas construction project and didn't get paid, a mechanic's lien is the most powerful tool you have. It attaches to the property itself, not to the person who owes you, which means the owner can't sell or refinance without dealing with your claim first. But the lien isn't self-perfecting for most claimants. Texas Property Code Chapter 53 imposes notice requirements and filing deadlines that vary depending on your contractual relationship with the owner, and missing any of them can destroy your lien rights entirely.

Texas is unusual in that it provides two types of mechanic's liens, a constitutional lien and a statutory lien, and understanding the difference between them is the starting point for protecting your payment rights.

Constitutional Lien Versus Statutory Lien

Article XVI, § 37 of the Texas Constitution grants mechanic's and materialman's lien rights and instructs the legislature to provide for their enforcement. The constitutional lien is self-executing, meaning it exists automatically when an original contractor performs work or furnishes materials under a direct contract with the property owner. No filing, no notice, and no affidavit are required to create it. However, the constitutional lien applies only to parties with a direct contractual relationship with the owner. Subcontractors, sub-subcontractors, and suppliers who don't have a contract with the owner don't have a constitutional lien.

Statutory liens under Chapter 53 provide broader protection. They're available to original contractors, subcontractors, sub-subcontractors, suppliers, design professionals (architects, engineers, surveyors), landscapers, and anyone else who furnishes labor or materials for construction or repair of a house, building, or improvement in Texas. Statutory liens also provide priority against subsequent purchasers and lienholders, which the constitutional lien alone may not. But statutory liens require strict compliance with notice and filing requirements. Missing a deadline or omitting required language from a notice can invalidate the lien.

For original contractors, the constitutional lien provides a safety net. If an original contractor misses a statutory filing deadline, the constitutional lien may still exist, though enforcing it requires filing suit within the applicable limitations period. For subcontractors and suppliers, there's no constitutional backstop. If you don't perfect the statutory lien, you don't have a lien.

The 2022 Overhaul

In 2021, the 87th Texas Legislature substantially amended Chapter 53, effective for all original contracts entered into on or after January 1, 2022. If the original contract (the contract between the owner and the general contractor) was signed before January 1, 2022, the old version of the statute applies, even if subcontracts were signed after that date. Both versions will remain in play for projects with older original contracts.

Several of the 2022 amendments simplified the process in important ways. Subcontractor-tier distinctions were eliminated. Under the old law, first-tier subcontractors (those with a direct contract with the original contractor) had different notice deadlines than second-tier subcontractors (those with a contract only with a first-tier sub). Under the new law, all subcontractors follow the same notice and filing requirements regardless of tier.

Service methods were expanded. Notices can now be served by certified mail or by any traceable private delivery service that can confirm proof of receipt (FedEx, UPS, and similar carriers). Weekend and holiday deadlines were addressed. If a deadline falls on a Saturday, Sunday, or legal holiday, it extends to the next business day. These changes apply only to projects with original contracts entered into on or after January 1, 2022.

Who Can File a Mechanic's Lien

Anyone who furnishes labor, materials, specially fabricated materials, or professional services for the construction or repair of an improvement on real property in Texas can claim a mechanic's lien. This includes general contractors, subcontractors at all tiers, material suppliers, equipment lessors (for equipment incorporated into the project), architects, engineers, surveyors, and landscapers.

Design professionals (architects, engineers, and surveyors) and landscapers have lien rights under Chapter 53, but their liens have a different inception date. Most mechanic's liens relate back to the date construction commenced, giving them priority over subsequently filed interests. Design professional and landscaper liens relate back to the date the lien affidavit is recorded rather than the date construction began, which can put them behind other lien claimants in priority.

Notice Requirements for Subcontractors and Suppliers

If you don't have a direct contract with the owner, you must send pre-lien notices before you can file a lien affidavit. Failing to send these notices, or sending them late, invalidates the lien. There's no cure for a missed notice deadline.

For non-residential projects (original contracts entered into on or after January 1, 2022), subcontractors and suppliers must send two notices.

A notice of unpaid claim to the original contractor must be sent no later than the 15th day of the second month following the month in which the labor was performed or materials furnished. If you furnished materials in March, this notice is due by May 15.

A notice of unpaid claim to both the owner and the original contractor must be sent no later than the 15th day of the third month following the month in which the labor was performed or materials furnished. If you furnished materials in March, this notice is due by June 15.

Both notices must substantially comply with the form prescribed in Texas Property Code § 53.056(a-2). They must be sent by certified mail or traceable private delivery service to the owner and original contractor at their last known business or residence addresses.

For residential construction projects (including new home construction, repairs, and renovations to an owner-occupied residence), the notice deadlines are the same, but the notices and the lien affidavit must include specific warning language prescribed by § 53.254. Failing to include the warning language invalidates the lien on homestead property.

Filing the Lien Affidavit

After sending the required notices, the claimant must file a lien affidavit with the county clerk in the county where the property is located.

For original contractors, the lien affidavit must be filed no later than the 15th day of the fourth month after the month in which the original contract was completed, terminated, or abandoned. If the project was completed in January, the filing deadline is May 15.

For subcontractors and suppliers, the lien affidavit must be filed no later than the 15th day of the third month after the month in which the original contract was completed, terminated, or abandoned. If the project was completed in January, the filing deadline is April 15.

For retainage claims, a subcontractor who properly sent a retainage notice under § 53.057 must file the lien affidavit no later than the 15th day of the third month after the original contract was completed, terminated, or abandoned.

A copy of the lien affidavit must be sent to the owner or reputed owner no later than the fifth day after the affidavit is filed with the county clerk. Texas Property Code § 53.055.

Your lien affidavit must be signed by you or an authorized representative and must include a sworn statement of the amount claimed, a description of the labor or materials furnished and each month in which the work was performed or materials delivered, the name and last known address of the owner, the name and last known address of the original contractor, a legally sufficient description of the property, and the claimant's name and mailing address.

The Owner's Statutory Retainage

Texas Property Code § 53.101 requires the owner to retain 10 percent of the original contract price (or 10 percent of the value of the work done under the contract, whichever is greater) during the project. These "reserved funds" are held for the benefit of subcontractors, suppliers, and laborers who have lien rights. If the owner pays out the full contract price without retaining the statutory 10 percent and a subcontractor later files a valid lien, the owner may be liable for the amount that should have been retained.

When a subcontractor sends a timely notice of unpaid claim to the owner, the notice "traps" funds in the owner's hands. Even if the owner hasn't yet received the subcontractor's notice, the statutory retainage creates a fund from which subcontractor claims can be satisfied. If the owner has already paid out all contract funds by the time the notice arrives, there may be nothing to trap, which is why subcontractors should send notices as early as possible rather than waiting until the deadline.

Foreclosure

Filing a lien affidavit preserves the lien. Enforcing it requires a suit to foreclose on the lien in the district court in the county where the property is located.

For non-residential projects, the claimant has two years from the last day the claimant could have filed the lien affidavit to file suit to foreclose. For residential construction projects, the deadline is one year. Texas Property Code § 53.158. Missing the foreclosure deadline extinguishes the statutory lien.

Removing an Invalid Lien

Property owners have the right to challenge a mechanic's lien they believe is invalid or unenforceable. Under Texas Property Code § 53.160, the owner can file a summary motion to remove the lien on an expedited basis. Grounds include failure to send required notices, failure to file the lien affidavit within the statutory deadline, or filing a lien for an amount the claimant knows exceeds what's owed. If the court removes the lien, the claimant may be liable for the owner's attorney's fees. Under the 2022 amendments, the owner must give the claimant at least 30 days' notice before the hearing on the motion, and the court may allow expedited discovery.

Homestead Properties

Perfecting a lien on a homestead is the most complex application of Chapter 53. Texas law provides strong protections for homesteads, and lien claims on homestead property must satisfy additional constitutional and statutory requirements beyond what non-homestead liens require.

For subcontractors, the lien depends on whether the original contractor complied with the homestead contracting requirements under Article XVI, § 50(a)(5)(A)-(D) of the Texas Constitution, which include a written contract signed by both spouses and filed in the county clerk's office. If the original contractor didn't comply, derivative claimants (subs and suppliers) may have no lien rights against the homestead at all, regardless of how perfectly they followed the Chapter 53 procedures.

Practical Recommendations

Send notices early. Don't wait until the deadline. If payment is overdue, send your notice of unpaid claim to the owner and original contractor immediately. Early notice traps funds in the owner's hands and demonstrates that you're protecting your rights.

Calendar every deadline from the first day of the project. The notice and filing deadlines under Chapter 53 run from the month in which labor was performed or materials furnished, and from the month in which the original contract was completed, terminated, or abandoned. If you don't know when the original contract was completed, you may miss a deadline without knowing it. In Page v. Wood Structural Components, Inc., 102 S.W.3d 720 (Tex. 2003), the Texas Supreme Court held that a subcontractor's lien deadline runs from the date the original contract is completed, terminated, or abandoned, even if the subcontractor didn't know when that happened.

Confirm whether the original contract was entered into before or after January 1, 2022, because the answer determines which version of Chapter 53 applies. Ask the general contractor or the owner, and document the answer.

Include all required information in the lien affidavit. An affidavit that omits the property description, the claimant's address, or the sworn statement of the amount claimed is defective and may be subject to removal under § 53.160.

Don't assume a constitutional lien protects you if you're a subcontractor. Constitutional lien rights extend only to parties with a direct contract with the owner. If you're a sub at any tier, your only lien right is the statutory lien, and it requires strict compliance with Chapter 53.

A mechanic's lien is the strongest payment protection available on a private construction project in Texas, but it's only as strong as the claimant's compliance with the notice and filing requirements. Every missed notice, every late affidavit, and every omitted piece of required information is a defect that can eliminate the lien entirely. Protect your lien rights from day one, not after the payment dispute has already started.
