Parole is a supervised release of a prisoner before the completion of his/her sentence.The prisoner eligible for parole has to be a convicted prisoner who has served the minimum period of his sentence specified by law. The minimum requirement of time served in the prison varies upon classes of prisoner as follow:

  • Excellent class is required to serve at least 2/3 of the latest sentence
  • Very good class is required to serve at least 3/4 of the latest sentence
  • Good class is required to serve at least 4/5 of the latest sentence


The prisoner being released by parole is subject to be supervised not more than 5 years. The prison official will examine and announce the name list of the qualified prisoners. Thereafter, those qualified prisoners have to prepare and inform the related information to the prison official such as accommodation and the name of a guarantor who promises to monitor the prisoner. Furthermore, the prisoners have to inform their relative or guarantor to contact the prison official for acquiring essential information and giving good cooperation with the prison official. For example, the guarantor is requested to ask for a copy of court judgment from the court.

The prison official takes 2-3 months to collect the related documents according to the specification of the Department of Corrections. There must be some coordination made with outside agencies such as provision of copy of court judgment from the court, recommendation of parolee’s behaviour from government official or village chiefs, investigated information of probation offices and information of high-profile drug offenders of Office of Narcotics Control Board etc.

All related documents will be reviewed by the Prison Parole Board and then be forwarded to the Department of Corrections. As soon as the Department of Corrections approves for the parole the prison will be notified to release and supervise the parolees until the termination of sentence.

However, parole is not the right that every prisoner will be granted as it relies on the Parole committee who will review the prisoner’s record and all related documents before granting the parole.

Foreign prisoners are eligible for parole as same as Thai prisoners are. Only the requirement is that foreign prisoners are obligatory to attain a reference letter from their national embassy verifying that the paroled prisoner has a true residence, address and reference person contacts. While on parole the embassy officer will cooperate with the department of corrections in order to monitor and report the following up of parole.
