Under Missouri Revised Statutes the court can only extend your probation by 1 year if you received a 5 year probationary term. Thus, you can end up with a total of 6 years. However, it is quite common to revoke an individual that has an SIS probation and resentence the defendant to a term of years in prison and then place them on an SES probation for another 5 years. With that being said, if you are currently on an SES type of probation then the court can only extend it by 1 year.
If the court is trying to revoke your probation I would suggest that you speak with attorney that deals with probation revocation hearings so that you know your rights. Good luck .
