What is the difference between a constitutional and a statutory mechanic's lien in Texas?

The constitutional lien arises from Article XVI, Section 37 of the Texas Constitution, is SELF-EXECUTING (no notice or filing needed to create it), and is available only to claimants in PRIVITY with the owner. The statutory lien arises under Property Code Chapter 53, is available to original contractors and derivative claimants alike, and must be PERFECTED through strict compliance with notice and filing deadlines. The statutory lien binds later purchasers once recorded; the constitutional lien generally does not bind a purchaser without notice.

Who can claim a constitutional lien?

Only a claimant with a DIRECT contractual relationship with the property owner — an original contractor. Subcontractors and suppliers who contracted with the general contractor rather than the owner are not in privity with the owner and cannot assert a constitutional lien; they must perfect a statutory lien under Chapter 53 or pursue a bond claim. The lien also attaches to buildings and articles made or repaired, so work like landscaping generally falls outside it.

If the constitutional lien is automatic, why file anything?

Because of notice. A constitutional lien generally will not be enforced against a subsequent third-party purchaser who had neither actual nor constructive notice of it, and nothing is recorded to supply that notice. Filing a notice of the lien with the county clerk does not create the lien, but it places the world on notice and protects the claimant against a later buyer. Statutory liens may also take priority, which is a further reason to perfect statutorily where possible.

Why is a homestead lien the hardest to perfect?

Because §53.254 layers contractual requirements on top of the ordinary notice rules and demands strict compliance. Under §53.254(a)–(e), the claimant and the owner must execute a WRITTEN CONTRACT before any labor or material is supplied; BOTH SPOUSES must sign if the owner is married; the contract must be FILED WITH THE COUNTY CLERK; and a contract made by an original contractor inures to the benefit of those working under that contractor. Only then do the warnings matter: §53.254(f) requires the affidavit to carry "NOTICE: THIS IS NOT A LIEN. THIS IS ONLY AN AFFIDAVIT CLAIMING A LIEN." at the top in at least 10-point boldface, and §53.254(g) requires the owner's notice to explain the withholding and 10 percent reservation rules. Repairs or renovations to an existing homestead improvement also implicate Article XVI, Section 50(a)(5).

What is the owner's 10 percent retainage?

It is the amount an owner must reserve during construction and for 30 days after completion of the contractor's work — 10 percent of the contract price or 10 percent of the value of the work performed. It defines the owner's exposure to claimants the owner never hired: apart from that required reservation, an owner generally is not liable to a subcontractor or supplier for amounts already paid to the contractor before the owner received written notice of the claim.

How long does a claimant have to foreclose a statutory lien?

Under §53.158(a), as revised effective January 1, 2022, suit must be brought not later than the FIRST ANNIVERSARY of the last day the claimant could have filed a lien affidavit under §53.052 — reduced from the prior two years. Subsection (a-2) permits extension to not later than the SECOND ANNIVERSARY of the date the affidavit was FILED, provided the claimant and the then-current record owner sign a written extension before the one-year period runs and record it in the same county, where it serves as notice to subsequent purchasers. The shorter window applies to statutory liens; a claimant in privity may argue for the longer general period on a constitutional lien.

Mechanic's & Materialman's Liens: Tex. Prop. Code Ch. 53

TL;DR

Texas gives contractors and suppliers TWO separate lien systems, and confusing them is the classic exam trap. The CONSTITUTIONAL lien comes from Article XVI, Section 37 of the Texas Constitution, which provides that mechanics, artisans, and material men of every class have a lien upon the BUILDINGS AND ARTICLES made or repaired by them for the value of their labor or materials. It is SELF-EXECUTING — no notice, no affidavit, no filing is required to create it — but it is available ONLY to a claimant in PRIVITY with the owner, meaning an original contractor who contracted directly with the owner. Subcontractors and suppliers without that direct contract cannot use it. Its weakness is notice: a constitutional lien generally will NOT be enforced against a later purchaser who had neither actual nor constructive notice. The STATUTORY lien comes from Chapter 53 of the Texas Property Code, is available to original contractors AND derivative claimants (subs and suppliers), and must be PERFECTED by strict compliance with notice and filing deadlines. A properly recorded statutory lien binds subsequent purchasers. Requirements tighten across three property categories — non-residential, residential non-homestead, and residential HOMESTEAD — with the homestead lien of a derivative claimant being the hardest to perfect, requiring the specific warning language of §53.254 in both the notice and the affidavit. A 2021 rewrite effective January 1, 2022 reshaped the chapter, including cutting the §53.158 deadline to foreclose a statutory lien from two years to ONE YEAR — extendable to no later than the SECOND ANNIVERSARY of the affidavit filing date by a written agreement with the then-current record owner, entered before the one-year period expires and recorded in the same county.

Two lien systems, one project

Most states give construction claimants a single statutory lien remedy. Texas gives two, operating in parallel and independently. Understanding which one a claimant has — and what each is good for — is the whole subject.

The constitutional lien exists because the Texas Constitution itself created it. Article XVI, Section 37 provides that "Mechanics, artisans and material men, of every class, shall have a lien upon the buildings and articles made or repaired by them for the value of their labor done thereon, or material furnished therefor; and the Legislature shall provide by law for the speedy and efficient enforcement of said liens." The Legislature answered that mandate with the mechanic's lien statute now found in Title 5, Chapter 53 of the Texas Property Code. The two yield similar protections but function separately and distinctly — a claimant may have one, the other, or both.

The constitutional lien: automatic but limited

The constitutional lien's great advantage is that it is SELF-EXECUTING. It arises as soon as the qualifying claimant furnishes labor or materials under a qualifying contract. There is no notice requirement, no deadline to send a pre-lien letter, and no affidavit that must be filed to bring the lien into existence. A contractor who blows every Chapter 53 deadline may still have constitutional lien rights to fall back on.

Its limits are equally important:

Privity is mandatory. Only a claimant with a DIRECT contract with the owner — an original contractor — can assert a constitutional lien. Subcontractors and suppliers who contracted with the general contractor rather than the owner do not qualify and must perfect a statutory lien or pursue a bond claim.

Buildings and articles only. The lien attaches to the buildings and articles made or repaired, not to land standing alone. Work such as landscaping or irrigation generally falls outside the constitutional language, so that work requires the statutory route.

No protection against a purchaser without notice. This is the practical weakness. A constitutional lien generally will not be enforced against a subsequent third-party purchaser who had neither actual nor constructive notice of it. Because nothing is recorded, an innocent buyer can take free of it. That is why prudent claimants file a notice of the constitutional lien with the county clerk even though filing is not required to create the lien — filing supplies the constructive notice the lien otherwise lacks.

The statutory lien: powerful but unforgiving

Chapter 53 provides the detailed procedure for asserting and enforcing a mechanic's lien, and it is available far more broadly — to original contractors, subcontractors, material suppliers, and, following the 2021 revisions, to architects, engineers, and surveyors. The trade-off is that a statutory lien must be PERFECTED, and Texas courts require compliance with the statute's notice and filing requirements.

The chapter's deadlines and notice obligations vary along two axes. The first is WHO the claimant is: an ORIGINAL CONTRACTOR contracted directly with the owner or the owner's agent, while a DERIVATIVE CLAIMANT did not. Derivative claimants carry the heavier notice burden because the owner has no direct relationship with them and needs to be told a claim exists. The second axis is WHAT the property is: non-residential (commercial), residential non-homestead, and residential homestead, in ascending order of strictness.

Unlike the constitutional lien, a statutory lien that is properly filed of record will be enforced against a subsequent purchaser, because the recording supplies constructive notice. Statutory liens may also take priority over constitutional liens, which is a further reason a claimant in privity should perfect statutorily rather than rely on constitutional rights alone. For how recording and notice determine priority generally in Texas, see our guide to the Texas recording statute and notice.

Feature	Constitutional lien (art. XVI, §37)	Statutory lien (Prop. Code Ch. 53)
Who may claim	Only claimants in PRIVITY with the owner	Original contractors AND derivative claimants
How it arises	SELF-EXECUTING — automatic	Must be PERFECTED by notice and filing
Attaches to	Buildings and articles made or repaired	The improvement and, per the chapter, the property
Purchaser without notice	Generally NOT enforceable	Enforceable once properly recorded
Deadline to foreclose	Longer general limitations period	ONE YEAR under §53.158(a); extendable to two years by recorded agreement under (a-2)

The homestead layer

Homestead property is where Texas lien law is at its strictest, and it is the most heavily tested corner of the subject. A lien on a homestead is valid only if the claimant strictly complies with Chapter 53's requirements, plus additional constitutional requirements.

Note first a definitional point that trips people up: HOMESTEAD is not the same as RESIDENCE. Homestead is defined by Property Code §41.002 with its urban and rural categories, while "residence" and related terms are defined within Chapter 53 itself. A property can be a residence without being a homestead.

Written contract first. The requirement that actually FIXES a lien on a Texas homestead comes before any notice or affidavit. Under §53.254(a)–(e), the person who is to furnish material or perform labor and the OWNER must execute a WRITTEN CONTRACT setting forth the terms of the agreement; the contract must be EXECUTED BEFORE the material is furnished or the labor is performed; if the owner is MARRIED, the contract must be SIGNED BY BOTH SPOUSES; if the contract is made by an ORIGINAL CONTRACTOR, it INURES TO THE BENEFIT of all persons who labor or furnish material for that original contractor; and the contract must be FILED WITH THE COUNTY CLERK of the county in which the homestead is located, who records it in records kept for that purpose.

Miss any of those and there is no homestead lien to perfect, however careful the later notices are. The both-spouses requirement in §53.254(c) reflects the same principle that runs through Texas homestead law generally — one spouse cannot unilaterally burden the homestead.

The warning requirements come next. Under §53.254(f), a lien affidavit relating to a homestead must contain a specified notice conspicuously printed, stamped, or typed at the TOP OF THE PAGE in a size equal to at least 10-POINT BOLDFACE or the computer equivalent, reading in full: "NOTICE: THIS IS NOT A LIEN. THIS IS ONLY AN AFFIDAVIT CLAIMING A LIEN." Under §53.254(g), the notice given to the owner under Subchapter C must include or attach a statement explaining that the owner's property may become subject to a lien if the owner fails to withhold payment sufficient to cover a claim after receiving notice of it, or fails, during construction and for 30 days after completion of the contractor's work, to reserve 10 PERCENT of the contract price or of the value of the work performed.

That 10 percent reservation is the owner's statutory retainage, and it defines the owner's exposure: apart from the required 10 percent, an owner is generally not liable to a subcontractor or supplier for amounts paid to the contractor before the owner received written notice of the claim. Where the work involves repairs or renovations to an existing improvement on a homestead, Article XVI, Section 50(a)(5) of the Texas Constitution imposes its own contractual mandates. For the broader homestead framework, see our guide to constitutional homestead protection.

What changed in the 2021 rewrite

A substantial revision of Chapter 53 took effect JANUARY 1, 2022, applying to projects with a prime contract entered into on or after that date. Several changes matter for the exam and for practice:

Shorter foreclosure deadline. Under §53.158(a), suit must be brought to foreclose the lien not later than the FIRST ANNIVERSARY of the last day a claimant may file the lien affidavit under §53.052 — reduced from the prior two years. Subsection (a-2) supplies the safety valve: the period may be extended to not later than the SECOND ANNIVERSARY OF THE DATE THE CLAIMANT FILED the lien affidavit, if before the one-year period expires the claimant enters into a WRITTEN AGREEMENT with the THEN-CURRENT RECORD OWNER to extend it. That agreement must be RECORDED with the clerk of the same county where the lien was recorded, and it is considered notice of the extension to any subsequent purchaser. Note that the two anchors differ: the one-year period runs from the last day the affidavit COULD have been filed, while the two-year outside limit runs from the date it WAS filed. Subsection (a-1) adds that where suit is pursued solely to discharge a lien because limitations expired, the claimant’s foreclosure rights are NOT revived. These rules govern statutory liens; a claimant in privity may still argue for the longer general limitations period on a constitutional lien.

Design professionals gained lien rights. Revised §53.021 removed the prior requirement that architects, engineers, and surveyors contract directly with the owner, so those professionals may now have statutory lien rights when they contract with a general contractor or a subcontractor.

Statutory form notices. Sections 53.056 (unpaid labor and materials) and 53.057 (contractual retainage) now require the use of statutory form notice letters set out in the text of the Property Code, replacing the prior practice of drafting notices freehand.

Second-tier subcontractors. Subcontractors without a contract with the original contractor no longer have abbreviated notice requirements.

Deadline computation and waivers. Section 53.003(e) provides that when a deadline or the last day of a period falls on a Saturday, Sunday, or legal holiday, the period extends to the next day that is not one of those. Lien waivers no longer require notarization.

Why this matters to a license holder

A real estate license holder does not file mechanic's liens, but the subject reaches licensed practice constantly. A recorded mechanic's lien clouds title and will surface on a title commitment, potentially delaying or killing a closing. A seller who recently completed construction or renovation may have unpaid claimants whose lien deadlines have not yet run — meaning a lien can appear AFTER the contract is signed. Because a properly perfected statutory lien binds subsequent purchasers, a buyer who closes without addressing the risk can inherit the problem.

That is why title insurance underwriting scrutinizes recent construction, and why lien waivers and affidavits are standard closing deliverables where work has been done. For how title insurance responds to recorded encumbrances, see our guide to Texas title insurance, and for the warranties a deed carries against encumbrances, see our guide to statutory deed warranties.

Bottom Line

Texas runs two parallel mechanic's lien systems. The CONSTITUTIONAL lien under Article XVI, Section 37 is SELF-EXECUTING and needs no notice or filing, but reaches only claimants in PRIVITY with the owner, attaches to buildings and articles rather than land alone, and generally cannot be enforced against a purchaser without actual or constructive notice — which is why prudent claimants record notice anyway. The STATUTORY lien under Property Code Chapter 53 is open to original contractors and derivative claimants, must be PERFECTED by strict compliance with notice and filing requirements, and once recorded binds subsequent purchasers and may outrank a constitutional lien. Strictness rises from non-residential to residential non-homestead to residential HOMESTEAD, where §53.254(a)–(e) first requires a WRITTEN CONTRACT executed BEFORE work begins, SIGNED BY BOTH SPOUSES if the owner is married, and FILED WITH THE COUNTY CLERK, and only then §53.254(f) requires the "NOTICE: THIS IS NOT A LIEN. THIS IS ONLY AN AFFIDAVIT CLAIMING A LIEN." heading in at least 10-point boldface at the top of the affidavit and §53.254(g) a specified owner warning about withholding payment and reserving 10 PERCENT during construction and for 30 days after completion. The 2021 rewrite effective January 1, 2022 cut the §53.158(a) foreclosure deadline from two years to ONE YEAR — extendable under (a-2) to the second anniversary of the affidavit filing by a timely written agreement with the then-current record owner, recorded in the same county — extended §53.021 lien rights to architects, engineers, and surveyors without owner privity, and required statutory form notices under §§53.056 and 53.057. For a license holder the practical point is that liens cloud title and can surface after contract, which is why recent construction draws underwriting scrutiny.
