Texas subcontractors can file a mechanics lien for unpaid change order work, even when the change order was never formally approved in writing, provided the work was performed at the owner's or GC's direction and you followed Texas's lien notice requirements under Tex. Prop. Code § 53.001 et seq. To preserve lien rights, subcontractors without a direct contract with the owner must serve a monthly notice of unpaid balance on the 15th day of the second month following each month in which labor or materials were furnished. Miss those monthly deadlines and you lose lien rights on the work performed in those months — permanently. A mechanics lien in Texas must then be filed by the 15th day of the fourth month after the last month of furnishing.
Does Texas Law Allow Liens for Unapproved Change Orders?
Texas mechanics lien law does not require a signed change order as a precondition for a lien claim. What the law protects is the value of labor and materials actually furnished to the project. Under Tex. Prop. Code § 53.021, any subcontractor or supplier who furnishes labor or materials under a contract with a general contractor — or any other person except the property owner — has lien rights on the improvement and the land. The statute doesn't condition those rights on whether a change order form was signed.
That said, "unapproved" is not the same as "unauthorized." To successfully claim lien rights on extra work, you need to show that someone with authority directed the work. Courts distinguish between work that was genuinely directed — even verbally — by the GC or owner, and work a sub performed unilaterally without any instruction. The former supports a lien. The latter is harder to defend.
This is where your documentation becomes the difference between getting paid and eating the cost.
What Are the Notice Deadlines for Texas Change Order Lien Claims?
For subcontractors without a direct contract with the property owner (which covers most subs), Texas law requires two separate notice steps under Tex. Prop. Code § 53.056 and § 53.057.
Monthly Notices (Second-Tier Subcontractors): You must send a written notice of unpaid balance to the owner and GC by the 15th day of the second month following each month in which you performed unpaid work. So if you did extra work in July and weren't paid, your notice is due by September 15th. Miss it, and you lose lien protection for July's work.
Lien Affidavit Deadline: After completing your work or when payment is overdue, you must file a lien affidavit with the county clerk in the county where the property is located by the 15th day of the fourth month after the last month in which you furnished labor or materials.
For change order work specifically, these deadlines run from the month the change order work was performed — not the month the original contract started. Treat each month of unpaid extra work as its own deadline trigger.
According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days, up from 49% just two years earlier. On change orders — where GCs often claim they need "owner approval" before cutting a check — waits stretch even longer. The notice deadline doesn't care about the GC's approval chain.
What Written Evidence Do You Need to Document Change Order Work?
Documentation is what separates a collectible lien claim from a disputed one that costs you attorney fees to enforce. For Texas unpaid change order work, your documentation package should include:
Direction to perform the work. Text messages, emails, field directives, or verbal instructions confirmed in writing afterward. If your superintendent got a verbal "go ahead" from the GC's project manager, send a confirming email that same day: "Per our conversation at 9 AM, we're proceeding with the additional framing on Grid 7 as directed."
Daily logs showing the extra work. Foreman daily reports that identify the crew, the hours, and specifically what was done that falls outside the base contract scope. These need to be contemporaneous — written the day the work happened, not reconstructed two months later.
Cost breakdown. Labor hours by worker, material quantities, equipment time, and any markup you're entitled to under your subcontract. Texas courts look at the reasonable value of work performed when calculating lien amounts, so your costs need to be documented and defensible.
Invoices submitted. Date-stamped copies of every invoice or change order request you submitted to the GC, with proof of delivery. If they ignored it, that's evidence too.
Photos and RFIs. Timestamped photos showing the extra work in place. If you submitted an RFI about the scope change and got direction back in writing, that's gold.
None of this documentation creates the lien. But it determines whether your lien survives a challenge.
How Does the Texas Prompt Payment Act Apply to Change Order Disputes?
The Texas Prompt Payment Act, codified at Tex. Prop. Code §§ 28.001–28.010, gives subcontractors a right to interest on late payments — and it applies to change order work. Once a GC receives payment from the owner, they must pay subcontractors within seven days for work included in that payment. If the GC doesn't pay within that window, interest accrues at 1.5% per month on the unpaid balance.
Here's where change orders create a trap: GCs sometimes claim that change order amounts weren't included in the owner's payment, so the seven-day clock hasn't started. That's a gray area, but it's not a blank check to delay indefinitely. If the owner paid a progress draw that included — or should have included — the value of your extra work, the Prompt Payment Act clock runs.
The Prompt Payment Act also allows you to recover attorney's fees and suspend work for non-payment after proper notice. Under § 28.009, a contractor or subcontractor who prevails in a Prompt Payment Act claim is entitled to reasonable attorney's fees. That's meaningful leverage when you're in a dispute over a $30,000 change order.
Is a Written Change Order Required Under Texas Law?
Texas law does not impose a blanket statutory requirement that all change orders be in writing to be enforceable. The written change order requirement comes from your subcontract — not from the statute books. Most standard subcontracts (including AIA and ConsensusDocs forms) require written authorization before extra work begins. If yours does, performing work without written approval puts you at risk.
But "at risk" isn't the same as "no recovery." Texas courts have enforced payment claims for extra work under theories of quantum meruit (the reasonable value of work performed) and unjust enrichment when: (1) the work clearly fell outside the original scope, (2) the owner or GC accepted and benefited from the work, and (3) the performing party had a reasonable expectation of payment.
What you can't do is ignore a written change order clause in your subcontract and then act surprised when the GC disputes payment. Read your contract. If it requires written authorization, send a written change order request before the work starts. If the GC says "just do it, we'll handle the paperwork later," get that instruction in writing. That written trail — even informal — is what converts "extra work" from a disputed verbal agreement into a lien-supported claim.
How Do You Send a Demand Letter for Unpaid Change Order Work in Texas?
A demand letter is your first formal move before litigation or lien enforcement. It does several things: it creates a paper trail, it starts the clock on certain legal remedies, and it sometimes triggers payment from GCs who would rather pay than deal with a recorded lien on their bonded project.
Your Texas demand letter for unpaid change order work should include:
- Project identification: Full property address and legal description, contract number, and names of all parties.
- Scope of disputed work: A clear, factual description of what was performed, when, and why it was outside the original scope.
- Dollar amount demanded: Itemized by labor, materials, and any applicable markup from your subcontract. Include the invoice numbers and dates.
- Statutory basis: Reference Tex. Prop. Code § 53.021 (lien rights) and §§ 28.001–28.010 (Prompt Payment Act) explicitly. GCs who know you know the law respond differently than GCs who think you're bluffing.
- Deadline to respond: Give 10–14 days. State plainly that failure to pay will result in lien filing and referral to counsel.
- Delivery method: Send via USPS Certified Mail with a Certificate of Mailing. This creates proof of delivery that holds up in court.
Send the demand letter to the GC and — if your notices are current — directly to the property owner. Keep a copy of everything.
What Is the Step-by-Step Process to Protect a Texas Change Order Claim?
Here's the practical sequence for protecting Texas unpaid change order work from the moment extra work is directed:
- Day of direction: Confirm the instruction in writing (email or text) before or immediately after starting the work.
- End of each work month: Submit a written change order request or invoice to the GC.
- 15th of the second month after each unpaid work month: Serve your monthly notice of unpaid balance on both the owner and GC via Certified Mail.
- After all extra work is complete: Send a formal demand letter if payment hasn't come.
- 15th of the fourth month after the last month you worked: File your lien affidavit with the county clerk.
- Within two years of lien filing: File suit to enforce the lien if payment still hasn't been made (Tex. Prop. Code § 53.158).
Miss step 3 for any given month and you lose lien coverage for that month's work. Everything else flows from keeping those monthly notice deadlines.
According to Rabbet's 2024 Construction Payments Report, slow payments cost the U.S. construction industry an estimated $280 billion in 2024, adding roughly 14% to total construction spending. Change orders are a disproportionate contributor — they're the payment category most frequently held up by disputes over scope, authorization, and owner approval chains.
Frequently Asked Questions
Can I file a lien for verbal change orders in Texas?
Yes. Texas mechanics lien law under Tex. Prop. Code § 53.021 does not require written change orders as a condition of lien rights. If someone with authority directed the work verbally, and you performed it, you have potential lien rights on its value. Your challenge is proving the direction happened — which is why written confirmations (texts, emails) sent at the time of the instruction are critical. A well-documented verbal direction is far stronger than a he-said/she-said dispute months later.
What if the GC says the owner never approved the change order?
That dispute is between the GC and the owner — it's not your problem as a sub, and it doesn't eliminate your lien rights against the property. Under Texas law, the property owner can be held liable for improvements they accepted even without direct authorization of every change. Your lien runs against the property regardless of the GC/owner payment dispute, as long as your notices are current and properly served.
How do I calculate how much to put in my lien for change order work?
Include all unpaid amounts for labor, materials, equipment, and applicable markup under your subcontract. Do not include amounts that are genuinely disputed as base contract items versus change order work — that confusion weakens your claim. Your lien amount should match your outstanding invoices for the extra work. Texas courts can reduce lien amounts if they find claims are overstated, and an overstated lien can expose you to liability.
Does the Texas Prompt Payment Act cover subcontractors directly?
Yes. Tex. Prop. Code § 28.002 covers subcontractors and requires GCs to pay within seven days of receiving payment from the owner for work included in that payment. For change orders, the question is whether the owner's payment included — or should have included — the extra work value. If it did, the seven-day clock runs. Violation of the Prompt Payment Act entitles you to 1.5% monthly interest and potential attorney's fees under § 28.009.
What county do I file my Texas lien in?
File your lien affidavit with the county clerk in the county where the property is physically located — not where your company is based or where the GC's office is. For large projects that straddle county lines, you may need to file in multiple counties. The county clerk's office can confirm the correct filing location. Always get a file-stamped copy of your lien affidavit for your records.
Can I file a lien on a bonded public project in Texas?
Public property in Texas is not subject to mechanics liens. For public projects — city, county, state, school district — your payment protection comes from payment bond claims under Tex. Gov't Code § 2253.001 et seq. (the Little Miller Act). The notice requirements and deadlines for payment bond claims are different from private project lien requirements. If your project is public, do not file a mechanics lien — file a bond claim.
What happens after I file a Texas mechanics lien for change order work?
Filing the lien affidavit puts the owner on notice that you have an unpaid claim against their property. It clouds the title, which creates pressure to resolve the dispute — particularly if the owner is trying to sell or refinance. You then have two years from the lien filing date to file a lawsuit to enforce it (Tex. Prop. Code § 53.158). If you don't sue within that window, the lien expires. Most disputes settle before litigation once a valid lien is on record.
How much does it cost to file a Texas mechanics lien?
County clerk filing fees vary by county but typically run $15–$40 for a lien affidavit. That's the government fee. If you use a service to prepare and mail your preliminary notices — which is where most subs lose their lien rights — LienFlash charges $24.99 per notice, which includes attorney-reviewed, state-compliant forms and USPS Certified Mail with a Certificate of Mailing PDF. Losing lien rights on a $40,000 change order because you skipped a $24.99 monthly notice is an expensive mistake.
