Blove29,
There is no court in Texas that provides thirty days for filing an answer after receiving a summons. What court, EXACTLY, issued the summons?
Small claims court has a ten day answer period (monday after ten days). County and District Courts have a twenty day period (monday after twenty days).
You can file an answer by mail. You don't have to show up.
However, after you filed "your notice of appearance", one of three things happens.
First, there may be a motion to strike your "notice of appearance" (not a correct answer) and a motion to enter a default judgment. You have to respond to that motion and show up in court.
Second, you might be served with a summary judgment motion. You have to respond within thirty days if personally served, 34 if by mail. You must also show up in court to defend this motion (after filing an answer).
Third, if there is no summary judgment motion, a trial date is set and you must show up for that.
Something is not correct/confused in your story. I suspect that you recieved additional documents after the summons, and I suspect that different parts of the legal process are being combined or confused.
Finally, what kind of judgment, EXACTLY, was entered? default, summary or final?
Have you gone to the courthouse and gotten an entire copy of the file to answer these questions?
