How do I know when my relative will be released from prison?

On admission to prison, a prisoner will be given an estimated date for his/her release. The majority of prisoners are entitled to remission at a rate of one quarter, depending on how well they behave for the remainder of their sentence, eg. A person serving a sentence of 4 years will be expected to serve 3 years in custody. Those who are serving a life sentence and have a sentence of one month or less do not benefit from remission.
