If you've had prior contact with the criminal justice
system and got some kind of probationary sentence
with a promise that your conviction would be set aside and dismissed upon completion of your probation, you got a deferred adjudication.
Not every probation plea results i that, and if it was not explained to you that you case would be dismissed when you fulfilled your requirements, it was probably not part of your deal
But to find out for sure, you could contact your lawyer, who could tell you. You could also go with proof of your identification to the clerk of the court
where you took your plea and ask him to look up the case on the computer
and see if your conviction was deferred.
If you don't need the information in a hurry, you could also order a copy of your official criminal history. You could obtain that from the state
itself. You could also get it from the source that the government itself accesses when doing a background check, which is the FBI.
It costs $18 and you can order their kit on line. Avoid the commercial websites that say they can check your record. They are frequently inaccurate.
