Oklahoma Supplementation of Record (OSR) is a process used by Oklahoma courts to supplement the official court record with documents that are not part of the original record. OSR can include documents such as transcripts, exhibits, pleadings, orders, and judgments that were not part of the original court record. There are two types of OSR: Supplemental Record and Supplemental Exhibits. The Supplemental Record is used to supplement and update the official court record with documents that were not included in the original record and is typically used for appeals. The Supplemental Exhibits are used to supplement the official court record with documents such as photographs, audio recordings, or video recordings that were not part of the original record and are typically used for trial proceedings.
