text: first probation violation for not changing address and no dna sample, how much time will my friend serve?   a probation violation basicly means they go back to serve the balance of what thier probation was.  if they had two years probation left, they go into prison for the remainder of the probation if they send them to prison.  what happens first is of course they get put into jail, pending a hearing,  they may stay in for several months waiting on a hearing.  at the hearing, the judge may or may not violate the probation.
