Texas Mechanics Lien Deadline Calculator, Counted in Months
Texas does not count a lien deadline in days. Property Code chapter 53 counts whole months after the month in which the work was provided, so labor on the second and labor on the thirty first of a month share one date, and the month you finish the job is usually not the month that matters. Put in the month you were on site and this gives you the notice date, the affidavit date, the five day copy to the owner, and the day suit has to be on file.
Worked example
These are the figures the calculator opens with and the answer it gives. Change anything above and every number below moves with it.
- Who you are on this jobSubcontractor or supplier
- What kind of projectCommercial, or anything that is not a residence
- Month the work was provided, or ended if you are the original contractorMarch
- Year of that month2026
- Does your contract hold retainageNo
- Days early you want the notice to go out7 days
First deadline, and it is the noticeJune 15, 2026
Every month of work carries its own notice deadline. Section 53.056(a-1) counts from the month during which the labor or materials were provided, not from the end of the job, so a crew on site from March to August owes six notices on six different dates. Missing March kills the lien for March's money even if the other five go out perfectly.
| Notice to the owner and the original contractor | June 15, 2026section 53.056(a-1)(1), the 15th of the third month after the month of the work |
|---|---|
| Put that notice in the post by | June 8, 2026keeping 7 days in hand, because 53.003(b) wants certified mail or a traceable service, and neither is instant |
| Lien affidavit filed with the county clerk | July 15, 2026section 53.052(b), the 15th of the fourth month after the month you last provided labor or materials |
| Copy of the affidavit to the owner | within 5 days of filingsection 53.055(a), and 53.055(b) sends a copy to the original contractor inside the same five days |
| Suit to foreclose the lien | July 15, 2027section 53.158(a), one year from the last day you could have filed, not from the day you did |
What this calculator assumes
- The month of the work is month zero. Sections 53.056 and 53.052 both count whole months after it, so work provided on the 2nd and work provided on the 31st of the same month share one deadline.
- For a subcontractor or supplier the trigger month is the month the labor or materials were provided, or, for specially fabricated materials that were never delivered, the month they would normally have been required if that is later. For an original contractor it is the month the work was completed, terminated, or abandoned.
- These are the dates for unpaid labor or materials. Contractual retainage runs on its own dates under sections 53.057 and 53.052(d), counted from a contract ending rather than from your last month on site, so this page flags it rather than folding it in.
- A deadline landing on a Saturday or Sunday is moved forward under section 53.003(e). That subsection moves legal holidays too, and the holiday calendar that binds you is the county clerk's, not this page's.
- This is the chapter as amended by House Bill 2237, in effect since 1 January 2022. Anything describing a second month notice to the contractor followed by a third month notice to the owner is the older law.
The first Texas deadline is not the lien
A subcontractor who waits for the job to end before thinking about a lien has usually lost part of it already. Section 53.056(a) says a claimant other than an original contractor must give the notice it prescribes for the lien to be valid, and section 53.056(a-1) dates that notice from the month during which the labor or materials were provided. Not the month the job ended. Not the month the invoice went unpaid. The month you were on site.
For a project that is not a residence the notice is due on the fifteenth day of the third month after that month. Work provided in March is noticed by June the fifteenth, whether the job runs another week or another year. For a residential construction project it is the fifteenth day of the second month, so March is noticed by May the fifteenth.
An original contractor does not send this notice at all, because 53.056(a) speaks to a claimant other than an original contractor and he already has the owner's ear. What he does not get is a longer filing window.
The month of the work is month zero
Every deadline in this chapter is a fifteenth. Section 53.052(b) puts a subcontractor's affidavit on the fifteenth day of the fourth month after the later of the month the claimant last provided labor or materials and the month undelivered specially fabricated materials would normally have been required. Section 53.052(a)(1) puts an original contractor's on the fifteenth day of the fourth month after the month his work was completed, terminated, or abandoned.
Count the way the statute counts. The month of the work is not month one, it is the month you count from, so March plus four months is July and the affidavit is due on July the fifteenth. Counting March as month one and filing in June is a month early and harmless. The expensive error is the other one, reading the fourth month as four calendar months from the day you worked and filing on the third of August.
Because the count runs in whole months, the day inside the month is irrelevant. That is generous on the thirty first and it is much less generous on the first, where a single day of work at the start of March buys exactly the same deadline as a full month of it.
Residential pulls everything in by a month
Section 53.001 defines a residential construction project as a project for the construction or repair of a new or existing residence, including improvements appurtenant to the residence, as provided by a residential construction contract. If that is the job, both stages move one month earlier: the notice under 53.056(a-1)(2) to the fifteenth of the second month, the affidavit under 53.052(a)(2) or 53.052(c) to the fifteenth of the third.
Nothing on a residential job announces this. The work looks the same, the invoices look the same, and the month that would have been comfortable on a commercial project is the month the notice was already late. If you run both kinds of work, the project type belongs in the same place you keep the address, because it is a date input and not a description.
Filing the affidavit is the middle of the job
Section 53.055(a) gives you five days from filing to send a copy of the affidavit to the owner at his last known business or residence address, and 53.055(b) sends a copy to the original contractor inside the same period if you are not one. That is five days after filing, not five business days and not five days after somebody gets round to it.
Then section 53.158(a) sets the outside date: 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 section 53.052. Read what the anniversary runs from. It is not the day you filed. A claimant who files in April on a July deadline gets no extra time at the far end, and a Texas lien left sitting while payment is discussed is a lien on a one year timer.
Section 53.158(a-2) allows that to be pushed to the second anniversary of the date the affidavit was filed, but only by a written agreement with the then current record owner of the property, recorded with the clerk of the same county. It is a document somebody has to sign, not a grace period.
When the fifteenth is a Saturday
Section 53.003(e) says that in determining the deadline or computing the period of days in which to provide a notice or to take any action required under this chapter, if the deadline or the last day of the period is a Saturday, Sunday, or legal holiday, the period is extended to include the next day that is not a Saturday, Sunday, or legal holiday. Roughly two fifteenths in every seven fall on a weekend, so this is an ordinary case rather than a rare one.
This page moves a weekend date forward and tells you when it has. It does not move legal holidays, because the list that binds you is the one the county clerk keeps, and the clerk's office is where the affidavit has to arrive. Check the date against that calendar before you spend the extra day.
The safer habit is to treat the roll as insurance rather than as time. Section 53.003(b) wants the notice delivered in person, by certified mail, or by another traceable private service that can confirm proof of receipt, and none of those land the same afternoon.
Questions people ask
Does the Texas lien deadline run from the end of the job?
No, and this is the mistake that costs the most money. Section 53.056(a-1) dates a subcontractor's notice from the month during which the labor or materials were provided, and section 53.052(b) dates the affidavit from the month the claimant last provided labor or materials. On a job running March to August, March's money is governed by March's dates. The end of the job is the trigger only for an original contractor, whose 53.052(a) deadline runs from the month his work was completed, terminated, or abandoned.
What are the dates if I worked in March on a commercial job in Texas?
The notice to the owner and the original contractor is due by June the fifteenth, the fifteenth day of the third month after March, under section 53.056(a-1)(1). The lien affidavit is due by July the fifteenth, the fifteenth day of the fourth month, under section 53.052(b). If the same work is a residential construction project both move a month earlier, to May the fifteenth and June the fifteenth.
Do I have to send a notice if I contracted directly with the owner?
No. Section 53.056(a) applies to a claimant other than an original contractor. You still file the affidavit on the fifteenth of the fourth month after your work was completed, terminated, or abandoned, the third month if it is residential, and you still have to send the owner a copy of the filed affidavit within five days under section 53.055(a).
Is unpaid retainage on the same dates?
No. If your contract provides for retainage, section 53.057(a-1) requires a separate notice of claim for unpaid retainage by the earlier of the thirtieth day after your own contract is completed, terminated, or abandoned and the thirtieth day after the original contract is terminated or abandoned. Section 53.052(d) then puts the affidavit for retainage at the fifteenth day of the third month after the month the original contract ended. Both run from a contract ending rather than from your last month on site.
How long do I have to sue after filing the lien affidavit?
Section 53.158(a) requires suit to foreclose not later than the first anniversary of the last day you could have filed the affidavit under section 53.052, which is not the day you actually filed. It can be pushed to the second anniversary of the filing date under 53.158(a-2), but only by a written agreement with the then current record owner that is recorded in the same county.
Did the 2022 changes move these dates?
Yes. House Bill 2237 rewrote the notice structure with effect from 1 January 2022, repealing subsections of both 53.056 and 53.057 and replacing the old notice letters with the forms now printed in 53.056(a-2) and 53.057(a-2). Anything you read that describes a second month notice to the original contractor followed by a third month notice to the owner is describing the law before that date.
