A: If your son has no previous record generally the State will recommend a deferred adjudication meaning if he completes probation successfully the charge will not be on his record. Juvenile records are sealed and can only be opened under limited circumstances. Probation for a juvenile is generally community sentence, stay out of trouble, go to school, and keep appointments with the probation officer. That being said conspiracy is difficult to prove in my experience.
A: If you are currently on probation and you fail to fulfill the requirements the State could revoke your probation and sentence you to serve the remainder of your sentence in jail or prison depending on the charge. If a revocation is filed in your case you could qualify for a court appointed attorney. I would not recommend doing this without an attorney.
