I assume you have had your probation transferred to Florida and are now being supervised by a Florida probation officer who sends monthly reports back to the Indiana court where you were sentenced..If that is the case, you can petition the Indiana court to terminate your probation. This is fairly common so long as you have done at least 1/2 of your probation, there have been no previous violations of probation and there is no restitution left to be paid. You should contact an attorney who practices in the jurisdiction in Indiana where you were originally placed on probation. That attorney will contact your Florida probation officer to hopefully get a favorable recommendation. Good Luck.
When it comes to early termination of a probationary term, the judge makes the ultimate decision. Usually, a favorable recommendation from the supervising probation agent is a necessity to achieving this objective. The defendant/probationer can file a request to the court for early termination. It sounds like you successfully completed close to 80 percent of your probationary term. Perhaps you can discuss this with your probation officer?
You should check with an Indiana attorney to see if you can terminate your probation since you have already served over half the probationary period. Florida law allows such termination after 50% of the probation if all conditions have been successfully met. My practice is in Tavares, FL where you are likely being supervised but it is the Indiana Court which would make the decision applying Indiana law. You will need a positive report from your Florida probation officer in order to bring a "motion for termination of probation." If you were represented by a public defender originally, they usually do not file this type of motion. You could file it yourself, but I strongly suggest you retain an attorney at the locale where your case was originally heard. Often you do not have to be physically present for the court to rule on such a motion, and if your probation officer and the prosecutor have no objection, most judges will grant the relief.
