How to File a Mechanics Lien in Texas: Affidavit, Filing, and Notices

To file a mechanics lien in Texas, you send the required preliminary notices to the owner and general contractor, prepare a sworn lien affidavit that meets Texas Property Code Section 53.054, record it with the county clerk in the county where the property sits, and mail a copy of the recorded affidavit to the owner (and to the general contractor if you’re a subcontractor) within five days. Every step has its own deadline under Chapter 53 of the Property Code, and missing any one of them can wipe out your lien rights for the work it covers.

Who Can File

Anyone who provided labor, materials, machinery, or equipment for construction or repair of an improvement to real property can claim a mechanics lien, provided the work was done under a contract with the owner or with someone acting on the owner’s behalf, such as a general contractor.¹ That covers general contractors, subcontractors, material suppliers, equipment lessors, and individual laborers.

Texas actually recognizes two kinds of mechanics liens. A constitutional lien arises automatically for anyone who contracts directly with the owner, with no filing required. But a constitutional lien doesn’t protect you against later buyers or lenders who take an interest in the property without knowing about your claim. To get that broader protection, and to preserve any lien rights at all if you don’t have a direct contract with the owner, you have to perfect a statutory lien through the notice, affidavit, and recording steps below.² Subcontractors and suppliers have no choice: the statutory process is their only route.

Send Preliminary Notices First

If you have a direct contract with the owner (an original contractor), you do not have to send a preliminary notice before filing your affidavit.² Skip to the affidavit section.

If you’re a subcontractor or supplier without that direct contract, you must send written notice to both the owner and the original contractor before your lien can be valid. The deadlines run month by month based on when you worked:

Commercial projects: no later than the 15th day of the third month after each month you provided labor or materials.
Residential projects: no later than the 15th day of the second month after each month you provided labor or materials.

Each month of work stands on its own. If you worked in March and April but only sent a timely notice for March, you lose lien rights for the April work.²

The notice has to follow the format set by the statute. It must include a warning statement telling the owner the property could be subject to a lien if funds aren’t withheld from future payments to the general contractor, along with the project details, your name and contact information, a description of the labor or materials you provided, the original contractor’s name, and the amount owed.² Send it by certified mail with return receipt requested so you can prove delivery. That notice does more than preserve your lien: it triggers the owner’s obligation to withhold funds from the general contractor to cover your claim.

One wrinkle for suppliers of specially fabricated materials that were never delivered because of nonpayment: the notice deadlines run from the month those materials would normally have been delivered, not from when you last worked.²

Check the Homestead Contract Rule Before You Spend More Time

Residential jobs come with a trap that kills more Texas liens than anything else. If the property is the owner’s homestead (their primary residence), the original contract between the owner and the contractor must be in writing, signed by both spouses if the owner is married, and filed with the county clerk in the county where the property is located.³ The contract should be filed before or at the same time as any lien notice. Without that filed written contract, no mechanics lien — original contractor’s or subcontractor’s — can attach to the homestead.

Before you invest time in preparing an affidavit for a residential job, confirm the original contractor filed a compliant written contract. If they didn’t, no procedural fix later on can save the lien.

Prepare the Affidavit

The lien affidavit is the sworn document that puts your claim on the public record. Texas Property Code Section 53.054 requires it to include:⁴

The exact dollar amount of the unpaid debt.
The name and last known address of the property owner.
The name and last known address of the original contractor.
A legal description of the property. A street address alone won’t do; pull the legal description from the property deed or the county appraisal district’s records.
A description of the labor or materials you provided, in enough detail to be identifiable.
The specific months during which you performed work or delivered materials.

Sign the completed affidavit in front of a notary public. Without the notary’s seal, the clerk will reject the filing or a court may later throw the lien out.

Record the Affidavit With the County Clerk

File the notarized affidavit with the county clerk in the county where the property sits. Deadlines depend on your role and the project type.

Original contractors:

Residential: file no later than the 15th day of the third month after the month work was completed, terminated, or abandoned.
Commercial: file no later than the 15th day of the fourth month after the month work was completed, terminated, or abandoned.

Subcontractors and suppliers:

Residential: file no later than the 15th day of the third month after the month you last provided labor or materials (or the month specially fabricated materials would normally have been delivered, if later).
Commercial: file no later than the 15th day of the fourth month after the month you last provided labor or materials (or that same specially fabricated materials date, if later).

These deadlines are firm. Filing one day late forfeits your statutory lien rights for the work the affidavit covers.²

Most counties accept in-person filing, and many larger ones offer e-filing. Recording fees vary but typically start around $25 for the first page and $4 for each additional page. The clerk will assign an instrument number or a volume and page number when the document is accepted. Ask for a file-stamped copy at submission; it’s your immediate proof that you met the deadline.

Send the Post-Filing Notice Within Five Days

Recording the affidavit isn’t the last step. Within five days after filing, you must send a copy of the recorded affidavit to the property owner at their last known business or residence address. If you’re not the original contractor, you must send a copy to the original contractor within the same five-day window.⁵

Use certified or registered mail so you have delivery confirmation. Missing this five-day notice can invalidate the lien if the owner or contractor challenges it.⁵ Keep the receipts and tracking records with the rest of your lien paperwork.

What Happens After You File

A recorded lien secures your position and gives you leverage, but it doesn’t pay you. Collecting typically means negotiating a payoff or suing to foreclose on the lien. Texas gives you one year from the last day you were allowed to file the affidavit to bring that lawsuit. You can extend it to two years from the date you filed the affidavit, but only if you and the current owner sign a written extension agreement before the original one-year period runs out.⁶ Miss both deadlines and the lien is unenforceable.

Once you’re paid, you’re on the clock the other direction. If the owner, the contractor, or whoever paid you sends a written request for a release, you must furnish a recordable release within 10 days.⁷ Sitting on a paid lien can leave you liable for the owner’s attorney’s fees and court costs if they have to sue to clear the title.
