does probation start at sentencing or when sign the probation paperwork?
First, parole is a conditional release from prison that allows a prisoner to rejoin the community after serving all, or a part, of his or her prison term. Probation, on the other hand, is a sentencing order that allows a person convicted of a crime to remain out of jail altogether. Secondly, in both cases, a person on probation or parole must follow certain court-ordered procedures and keep from getting into trouble with the law.
