This is a most unfortunate situation. Frankly, I don't see how he can clear up his record without divulging his mother's actions.  She is guilty of fraud, forgery, and several other offenses.  What they need to do know is to sit and speak with a criminal attorney.  Qualified counsel can best advise as to the specifc of this matter. Until his mother's actions are divulged, he won't be able to clear his credit.
