A technical violation occurs when a probationer fails to comply with a condition of probation that is not itself a new crime — such as missing an appointment, failing a drug test, or leaving the state without permission. A substantive violation occurs when a probationer is arrested for or convicted of a new criminal offense while on probation. Substantive violations are generally treated more seriously, but both types can result in revocation and incarceration. An attorney can help you navigate either type of violation effectively.
