Attorney Roe Response:
Usually, if you were placed on probation, the date in which to register should appear on the terms and conditions of probation. If it does not, contact the attorney who handled your matter and inquire. You can also go to the courthouse, ask for a copy of the minutes on 8/7/12 to see what the record reflects. Either way, get hopping because you do not want a violation of probation or diversion/Prop 36 fall-off filed against you.
