Of course, the flip side to this is that your fiancé never contacted his PO for three months after he KNEW his missed an appointment...even knowing where his PO was employed, knowing his /her phone number, etc. etc. etc. A PO is not a babysitter. it was your fiancé's responsibility to contact the PO, not the other way around!
Correct. Your fiancé failed to comply with the terms of his probation. Probation violations result in warrants and arrest. What did you or your fiancé expect would happen after he decided to just blow off the conditions of his probation?
What MAY happen is that everything your fiancé did during his probation (costs, classes, time, etc.) gets flushed down the toilet and counts for squat. The full sentence for your fiancé's offense is re-imposed and he gets that fine along with jail time. That is worst case, but it IS possible.
What is likely to happen (depending on his prior criminal record and how much he has pissed off the judge that gave him the break of probation that your fiancé pissed on) is that your fiancé's probation is extended...likely with some new, more strict conditions.
