You do not say whether this is a civil or criminal case. Either way, the avenue to fix is to file a motion to quash the subpoena. There are also certain requirements that must be met for an out of state subpoena to be valid. I would recommend reposting your question under Texas lawsuits and include more details as to whether civil or ciminal and the court involved. Did they send a check for expenses and how was it served. This will allow the texas attorneys a better opportunity to answer your question.
