Even if your boyfriend can get the conviction expunged, it won't make the new charge go away. Beyond that, Florida appears to permit expungement only where the charge is dismissed, nolle prossed, or results in acquittal, provided that the applicant has not been found guilty of a subsequent offnese. It also permits criminal records to be sealed where there is no adjudication of guilt, such as where a defendant receives a delayed disposition. But Florida does not appear to offer similar remedies following conviction.

If he has not already done so, your boyfriend needs to consult a criminal defense lawyer.
