If you were convicted of a felony 18 years ago, the felony conviction is still on your record. If you want to try and get it expunged (removed) I suggest that you consult with a criminal defense attorney to see if there is a chance that this can be done.Courts in determining whether to grant or deny a request to expunge one's conviction look to see what the conviction was for, how long ago was the conviction, what the person who was convicted has done since the conviction and the reasons for the desired expungement.
