Missouri Exhibit A is a document used in the state of Missouri to provide evidence for a court case. It consists of two parts: a copy of the document that is being used as evidence and an affidavit signed by a custodian of records. It is typically used in civil cases, such as divorce proceedings. There are three different types of Missouri Exhibit A: Affidavit of Record, Affidavit of Evidence, and Affidavit of Identification. An Affidavit of Record is used to certify that a document is an accurate copy of the original. An Affidavit of Evidence is used to establish the authenticity of a document and to provide evidence that it is related to a particular case. An Affidavit of Identification is used to identify a person or document. All three types must be signed by a custodian of records to be valid.
