Thanks for the chance to assist
Here is the law for TX for expungement
Tex. Code Crim. Proc. art. 55.01 (2007)
Art. 55.01. Right to Expunction
(a) A person who has been placed under a custodial or noncustodial arrest for commission of either a felony or misdemeanor
is entitled to have all records and files relating to the arrest expunged if:
(1) the person is tried for the offense for which the person was arrested and is:
(A) acquitted by the trial court
, except as provided by Subsection (c) of this section; or
(B) convicted and subsequently pardoned; or
(2) each of the following conditions exist:
(A) an indictment or information charging the person with commission of a felony has not been presented against the person for an offense arising out of the transaction for which the person was arrested or, if an indictment or information charging the person with commission of a felony was presented, the indictment or information has been dismissed or quashed, and:
(i) the limitations period expired before the date on which a petition for expunction was filed under Article 55.02; or
(ii) the court finds that the indictment or information was dismissed or quashed because the presentment had been made because of mistake, false information, or other similar reason indicating absence of probable cause
at the time of the dismissal to believe the person committed the offense or because it was void;
(B) the person has been released and the charge, if any, has not resulted in a final conviction and is no longer pending and there was no court ordered community supervision under Article 42.12 for any offense other than a Class C misdemeanor; and
(C) the person has not been convicted of a felony in the five years preceding the date of the arrest.
(a-1) Notwithstanding Subsection (a)(2)(C), a person's conviction of a felony in the five years preceding the date of the arrest does not affect the person's entitlement to expunction for purposes of an ex parte petition filed on behalf of the person by the director of the Department of Public Safety under Section 2(e), Article 55.02.
(b) Except as provided by Subsection (c) of this section, a district court may expunge all records and files relating to the arrest of a person who has been arrested for commission of a felony or misdemeanor under the procedure established under Article 55.02 of this code if the person is:
(1) tried for the offense for which the person was arrested;
(2) convicted of the offense; and
(3) acquitted by the court of criminal
(c) A court may not order the expunction of records and files relating to an arrest for an offense for which a person is subsequently acquitted, whether by the trial court or the court of criminal appeals, if the offense for which the person was acquitted arose out of a criminal episode, as defined by Section 3.01, Penal Code, and the person was convicted of or remains subject to prosecution for at least one other offense occurring during the criminal episode.
(d) A person is entitled to have any information that identifies the person, including the person's name, address, date of birth, driver's license number, and social security number, contained in records and files relating to the arrest of another person expunged if:
(1) the information identifying the person asserting the entitlement to expunction was falsely given by the person arrested as the arrested person's identifying information without the consent of the person asserting the entitlement; and
(2) the only reason for the information identifying the person asserting the entitlement being contained in the arrest records and files of the person arrested is that the information was falsely given by the person arrested as the arrested person's identifying information.
YOu can see the entire section here
THere is NO automatic drop off
Further, very few people who are convicted actually qualify. Look at para (a)(2) above to see if you qualify.
If yes, you can file yourself. The steps are in the link I post above. Since you are corresponding with the court, you would be well served to at least have a lawyer assist with this...i suspect you can find one who will do this for a reduced rate.
Also, look here to see if you even have a record in TX
