In the State of Texas your right to an Expunge your criminal record is very limited. To qualify for an immediate Expunction of your criminal record you must:
If your case was dismissed because of lack or evidence or insufficient evidence, then you must wait until the Statute of Limitation for your case has expired before you can file for an Expunction. The Statute of Limitation for all Misdemeanor offenses is two years from the date of offense. CCP Art. 12.02. The Statute of Limitation for Felony offenses varies from three years to ten years, and in some cases there is no Statute of Limitation. CCP Art. 12.01.
You may believe that you are entitled to an Expunction if you have successfully completed a Deferred Adjudication probation, this is because at the time of your guilty plea the Judge said “if you successfully complete probation then your case will be dismissed and you will have no conviction”. That is not totally correct, the statute specifically excludes an Expunction if your case ended with a Deferred Adjudication probation or community supervision. You are only entitled to file for an Expunction in a very limited number of cases. However it is likely that you are entitled to file a Petition for Non-Disclosure, which will result in a court order that prohibits the government from sharing with the general public information regarding your Deferred Adjudication.
