It may be possible to seal an aggravated assault if you are placed on deferred adjudication. If you successfully complete deferred adjudication you may apply for an Order of Nondisclosure sealing the record five years from the date of discharge from deferred adjudication community supervision. An expunction is different from an Order of Non-disclosure (sealing order). You may expunge the record only if you are found not guilty, or the case is dismissed, your case is never presented to a Grand Jury and the statute of limitations has expired, or a Grand Jury declines to indict you and the statute of limitations has expired. Even then, it can be incredibly challenging to seal or expunge criminal records. You will make things far easier on yourself by avoiding a conviction in the original trial rather than attempting to rewrite the past retroactively.
