No, unfortunately, as I mentioned, no
criminal conviction can be expunged in Texas unless it has been pardoned, only arrest records. Please refer to the links that I gave your father both for the confirmation that convictions cannot be expunged in Texas and also for the procedures for a pardon.
If I were you, I would use an attorney to assist you since there are several steps, including the gathering of records and the artful writing of your request for a pardon. There are some criminal defense attorneys who have a practice that includes pardons.
I, like the other Experts on this site, am here to assist customers like you. However, we do so in anticipation of being paid for our efforts, just like other professionals do, since this is our livelihood and not a hobby. To that end, I am more than happy to clarify my answer to you and answer any related follow up questions that you might have for the value that you have offered for the question. In return, I ask that you show good faith in compliance with the TOS by accepting my answer, whether the news is good or bad, so that I will be paid for my efforts. Please let me know if you experience technical difficulties when attempting to ACCEPT my answer by clicking on the green button. That way I can notify customer service.
