I am in violation of my probation, because I missed an appointment with my probation officer in Nov. '09,(that I didn't know of), and for attmiting to the use an of illegal drug. Although I did go to the probation office in Nov. to see my probation officer, who wasn't there at the time. Now he's filed for my probation to be revoked. Does anybody know what to do??

Hire an attorney to represent you at the hearing.

The missing the meetting is minor, you seem to brush the issue of drug use, that is enough to revolk probation even without the meeting
