The deadline to answer an amended petition in Texas turns on one question: have you already answered the original petition? If you filed a general denial, Texas Rule of Civil Procedure 92 presumes that denial automatically extends to the amended claims, and you typically do not need to file anything new. If you have not yet answered, your deadline is the same as for the original petition: by 10:00 a.m. on the Monday next after 20 days from the date you were served.1Texas Rules Project.

Both answers deserve some unpacking, because the wrong assumption in either direction can cost you.
When Your General Denial Already Covers the Amendment
This is the scenario most defendants overlook, and it is the one that matters most. Rule 92 provides that a general denial “shall be presumed to extend to all matters subsequently set up by the plaintiff.”2Texas Rules Project. Texas Rule of Civil Procedure 92 – General Denial When the plaintiff amends the petition, your original general denial stretches automatically to cover the new allegations. You are not in danger of default simply because the petition changed and you did not file a fresh answer.
That protection has a limit. The Rule 92 presumption keeps you from losing the case by default, but it does not raise affirmative defenses on your behalf. If the amended petition adds a new cause of action, and you have a defense specific to that claim, such as the statute of limitations on a newly added fraud count, you need to plead it yourself. The denial carries forward; the defenses do not.
So the practical rule is this: if your general denial is on file and the amendment is just a sharper version of what the plaintiff already alleged, you can usually sit tight. If the amendment adds genuinely new claims that trigger specific defenses, file an amended answer that raises them.
When You Need to File a New Answer
Two situations require you to actively respond to an amended petition.
The first is that you have not answered at all. If the plaintiff files an amended petition before you have filed anything, the amended petition becomes the operative pleading, and you must answer it. Under Rule 64, an amended petition is “entire and complete in itself” and replaces every earlier version.3Texas Courts. Texas Rules of Civil Procedure – Rule 64 Your deadline is 10:00 a.m. on the Monday next after 20 days from the date you were served with the amended petition.1Texas Rules Project. Texas Rule of Civil Procedure 99 – Issuance and Form of Citation If your deadline for the original petition has not yet run, you still have at least until that date. Use whichever gives you more time.
The second situation is subtler. Your original answer used specific denials rather than a general denial, and the amended petition adds allegations your specific denials do not address. Allegations you have not denied can be treated as admitted. In that case you need to file an amended answer that reaches the new material.
If you have already answered and the amendment introduces new claims requiring affirmative defenses, no single rule sets a fixed number of days for your amended answer. File it promptly and well before trial. If the court has issued a scheduling order, follow the cutoff it sets for amended pleadings.
How to Count the 20 Days
Texas Rule of Civil Procedure 4 governs the math.4Texas Courts. Texas Rules of Civil Procedure March 1 2026 – Rule 4 Start counting the day after you are served. The day of service itself does not count. Include every calendar day after that, weekends and holidays included.
Once you have 20 days, look at the next Monday. Your answer is due by 10:00 a.m. that Monday. If that Monday is a legal holiday, like Labor Day, the deadline rolls to the end of the next business day.4Texas Courts. Texas Rules of Civil Procedure March 1 2026 – Rule 4
A separate quirk in Rule 4 excludes weekends and holidays from any time period of five days or fewer. That does not change the 20-day answer window, but it can matter if a scheduling order gives you a shorter deadline to respond to something later in the case.
What Happens if You Miss the Deadline
If you never file an answer and the deadline passes, the plaintiff can take a default judgment. Rule 239 lets the plaintiff move for default any time after the answer was due, as long as no answer is on file and the return of service has been on file for the required period.5Texas Courts. Texas Rules of Civil Procedure – Rule 239 A default judgment is a final ruling in the plaintiff’s favor without any hearing on your side of the case.
The court does not enter default automatically the moment you miss your deadline. The plaintiff has to ask for it, and still has to prove up damages. But you lose the ability to contest liability, because every factual allegation in the petition is treated as admitted. The resulting judgment can cover the full amount the plaintiff requested, plus court costs.
If you filed an answer to the original petition and the plaintiff later amends, this risk largely falls away. A plaintiff cannot take a default against a defendant who has an answer on file, and your general denial extends to the amended pleadings under Rule 92.2Texas Rules Project.

Setting Aside a Default Judgment
If a default has already been entered against you, the window to undo it is narrow. File a motion for new trial within 30 days after the judgment is signed.6Texas Rules Project. Texas Rule of Civil Procedure 329b – Time for Filing Motions After 30 days the trial court loses the power to vacate the judgment, and your only remaining option is appeal.
Texas courts evaluate these motions under the three-part test from Craddock v. Sunshine Bus Lines. You must show all three:7Texas Courts. Supreme Court of Texas – Craddock Analysis
- Your failure to answer was not intentional or the result of conscious indifference, but was due to accident or mistake.
- You have a meritorious defense that, if true, would change the outcome.
- Setting aside the judgment will not delay the case or otherwise unfairly prejudice the plaintiff.
Courts apply this test seriously. “I forgot” or “I didn’t think it mattered” will not clear the first prong. Genuine confusion about service, a medical emergency, or a documented calendaring error can. On the meritorious defense element, you do not have to prove you will win. You only have to show your defense is not frivolous and would entitle you to a trial.
How to File Your Answer
E-filing is mandatory for attorneys in Texas district and county courts and strongly encouraged for self-represented parties.8Office of Court Administration. eFileTexas.Gov – Official E-Filing System for Texas File through efiletexas.gov. Create an account, choose to file into an existing case, enter the case number from the petition, and upload your answer. The system serves the opposing party electronically.
In justice courts that do not use e-filing, deliver your answer to the court clerk in person or by mail, and separately serve a copy on the plaintiff or their attorney. Add a certificate of service to the answer stating the date and method of delivery. Keep a file-stamped copy. If anyone later disputes whether you met your deadline, the stamp is your proof.
Label the pleading correctly under Rule 64, identifying what it responds to, such as “Defendant’s Original Answer” or “Defendant’s First Amended Original Answer.” A general denial is enough to prevent default, but if the amended petition raises new claims that trigger affirmative defenses, plead those defenses in the same document. They are waived if you do not raise them.
