It is technically possible to expunge a criminal record in Texas without the help of a lawyer. However, it is highly recommended that you hire a criminal defense DUI attorney to guide you through the process. An attorney can:
Advise you on your eligibility for expunction.
Determine the specific laws and regulations that apply to your case.
Guide you through the necessary legal steps.
Help prepare and file the necessary paperwork.
Notify the relevant agencies and the district attorney's office.
Represent you at any hearings.
