Yes, a good DUI attorney may be able to help you. It seems that you have enough circumstantial evidence to support your defense to the DUI charge, it is highly unlikely that your Ex will admit to driving since that opens him up to criminal prosecution for hit and run. All of the charges you face require you to be driving, if you were not driving then you have a defense. You have 10 days to contact the DMV and request a hearing, you should talk to a DUI lawyer between now and the 10 day limitation for requesting a hearing.
