Probation in criminal law is a period of supervision over an offender, ordered by the court instead of serving time in prison.
In some jurisdictions, the term probation applies only to community sentences (alternatives to incarceration), such as suspended sentences. In others, probation also includes supervision of those conditionally released from prison on parole.
An offender on probation is ordered to follow certain conditions set forth by the court, often under the supervision of a probation officer. During the period of probation, an offender faces the threat of being incarcerated if found breaking the rules set by the court or probation officer.
