You Have Been Served. Now the Clock Is Running.
Getting served with a lawsuit in Texas is disorienting. A process server hands you papers — or you find them taped to your door — and suddenly there is a deadline hanging over you that most people have never heard of. Here is the part that matters: in Texas, you do not get 30 days. You do not get “about a month.” You get a very specific Monday morning, and if you miss it, the plaintiff can win without you ever telling your side.
Thank you for reading this post, don't forget to subscribe!This guide walks through exactly how the Texas answer deadline works, how to calculate yours to the day, and the traps that catch even experienced litigants.
The Rule in Plain English: TRCP 99
Texas Rule of Civil Procedure 99 controls the deadline. The citation you were served with must command you to file a written answer with the clerk on or before 10:00 a.m. on the Monday next after the expiration of twenty days after the date of service.
Read that again, because every word does work:
- Twenty days — counted from the date you were served, including weekends and holidays.
- The Monday next after — you do not answer on day 20. You answer on the first Monday after those 20 days run out.
- 10:00 a.m. — not end of business. Ten in the morning, sharp.
How to Calculate Your Answer Deadline (Step by Step)
Follow these steps exactly:
- Pin down your service date. This is the day the papers were actually delivered to you (or a legally valid substitute), not the day the lawsuit was filed.
- Count forward 20 days, starting with the day after service as day 1. Count every day — weekends and holidays included.
- Find the next Monday after day 20. That Monday is your answer date. (If day 20 itself is a Monday, you go to the following Monday.)
- File by 10:00 a.m. on that Monday with the clerk of the court that issued the citation.
Worked example
Say you are served on Wednesday, October 14, 2026. Day 1 is October 15. Count 20 days: that lands on Tuesday, November 3. The next Monday after November 3 is Monday, November 9, 2026. Your written answer must be filed by 10:00 a.m. on November 9.
One more, because this is where people slip: served on Monday, October 12. Twenty days later is Sunday, November 1. The next Monday is November 2 — but check whether the court is open (if November 2 were a court holiday, the deadline would roll to the next day the court is open). Always verify court holidays.
The 10:00 a.m. Trap Is Real
Most lawyers calendar the answer day and assume a few hours of slack. Texas courts do not give slack. In G&C Land v. Farmland Management Services, the plaintiff took a $3 million+ default judgment at 10:15 a.m. on answer Monday — fifteen minutes past the deadline (No. 14-10046, 5th Cir. Sept. 23, 2014). The court later set it aside, but only after expensive motion practice that nobody wants. Calendar 10:00 a.m., then file the Friday before if you can.
Special Cases That Change the Deadline
Service by publication
If you were served by publication (common when a defendant cannot be found), the window is longer: 42 days from the date the citation was issued, with the answer due on the Monday after that period.
Substituted service
Service left with someone at your home or posted on your door still starts the 20-day clock from the effective service date shown on the officer’s return. Do not assume “I never personally received it” pauses anything — check the return of service.
Out-of-state defendants
The same Monday-after-20-days rule applies, but service itself often takes longer to complete. Your 20 days run from the date service was legally effected, not the date the lawsuit was filed.
If the court is closed on your Monday
Under TRCP 4’s computation rules, if the last day falls on a Saturday, Sunday, or legal holiday, the period runs to the end of the next day that is none of those. Verify against the court’s holiday schedule.
What Happens If You Miss It
The plaintiff can ask the court for a default judgment — meaning they win without you presenting a defense. That said, Texas practice has a safety valve: if the judge has not yet signed a final judgment, you can usually still file your late answer and get back in the case. Call the clerk, ask whether a final order has been signed, and file immediately. Do not wait to “talk to a lawyer first” if the deadline is today — file a general denial now, get counsel after. (Our guide on what to do when you miss a court deadline covers the federal side of this problem.)
Do Not Confuse This With Federal Court
If you were served in a federal case, different rules apply — generally 21 days under FRCP 12, not the Texas Monday rule. Suing in the wrong system with the wrong deadline is its own malpractice trap. See our Texas court deadlines guide for how TRCP 4 computation works across motion types, and use our legal deadline calculator to double-check any date math.
FAQs
How many days do I have to answer a lawsuit in Texas?
Twenty days from the date of service, plus time to reach the next Monday. Your written answer is due by 10:00 a.m. on the Monday after the 20-day period expires (TRCP 99).
What if the 20th day falls on a Monday?
You go to the following Monday. The rule says the Monday next after the expiration of the 20 days.
Do weekends count in the 20 days?
Yes. Count every calendar day, including weekends and holidays. Weekends only matter at the end: if your answer Monday is a court holiday, the deadline rolls to the next open court day.
Can I file my answer late in Texas?
Often, yes — if the judge has not signed a final judgment yet, you can usually file a late answer. Call the clerk to check, then file immediately.
Does the 10:00 a.m. deadline really mean 10:00 a.m.?
Yes. A $3M+ default judgment was taken at 10:15 a.m. on answer Monday in G&C Land v. Farmland. File early.
Is the deadline different if I was served by mail or publication?
Service by publication gives you 42 days from issuance instead of 20. For other methods, the 20-day clock runs from the effective service date — and separate TRCP 21a rules can add 3 days to deadlines triggered by mailed papers in ongoing litigation.
