What type of legal document indicates that an offender has fulfilled all sentence conditions?

The correct choice is a certificate of discharge. This document serves as formal acknowledgment that an individual has successfully completed all conditions and requirements of their sentence, including any probation or parole stipulations. When an offender fulfills their obligations—such as attending mandated counseling sessions, making restitution payments, or maintaining a clean record for a specified period—the certificate of discharge is issued.

This document is vital because it signifies the end of the offender's legal obligations related to their sentence, allowing them to reintegrate into society without further legal restrictions. It can also have a substantial impact on the individual's ability to access employment, housing, and other opportunities that require a clean legal standing.

The other options do have significant roles in the legal context but differ in their function. A certificate of rehabilitation is typically utilized to demonstrate an individual's rehabilitation and may support their application for certain rights but does not necessarily indicate full completion of sentence conditions. A final judgment refers to the last decision made by a court in a case but does not confirm compliance with sentence requirements. A pardon letter is a form of clemency that removes certain legal consequences of a conviction but is not the same as completing all sentence conditions.
