Rather than making a motion to seal your criminal file as to a criminal conviction, you should consider retaining a criminal defense attorney about the possibility of filing a motion to expunge your prior conviction instead. An expungement motion is a process where a convicted person seeks to have the conviction against him or her eliminated.If the motion is granted, the conviction for all intents and purposes no longer exists. There is no guarantee that a motion for an expungement in your situation would be granted, but it is worth exploring.
