Oklahoma Articles of Correction (AOC) are legal documents that are used to correct errors made on record documents, such as birth certificates, marriage certificates, and death certificates. There are four different types of AOC's: Correction of Name, Correction of Date, Correction of Other Errors, and Correction of Unofficial Records. A Correction of Name AOC is used to change the name of a person on a document, such as in a case of a misspelled name. A Correction of Date AOC is used to correct the date of an event on a record document, such as a birth or death date. A Correction of Other Errors AOC is used to correct errors on a document, such as a misspelling of a name or a wrong birth or death date. A Correction of Unofficial Records AOC is used to make corrections on records that were not issued by the state, such as a church record or family Bible record. All AOC's must be completed and signed by a judge in order for the corrections to be accepted by the state.
