The Pennsylvania Oath of Subscribing Witness is a formal document used to verify the identity of a witness when giving testimony or depositions in a legal matter. This document is also known as an affirmation of identity and is commonly used in the state of Pennsylvania. The Oath is usually sworn before a Notary Public or other authorized officer and requires the witness to swear or affirm that they are the person named in the document and that they are giving truthful statements. The Pennsylvania Oath of Subscribing Witness comes in two forms: the Pennsylvania Affirmation of Identity and the Pennsylvania Subscribing Witness Oath. The Affirmation of Identity simply requires the witness to affirm that they are the person named in the document and that the information they are providing is truthfully given. The Subscribing Witness Oath requires the witness to swear or affirm that they are the person named in the document, that the information they are providing is truthfully given, and that they have seen the document they are testifying about and that it is genuine.
