The Pennsylvania Oath of Non-Subscribing Witness is an oath taken by witnesses in Pennsylvania who are not subscribing members of an organized religion. It is a legal document that is used in place of a traditional religious affirmation. This oath is used in lieu of a sworn statement and is accepted in most courts as valid evidence. There are two types of Pennsylvania Oath of Non-Subscribing Witness: the standard oath and the expanded oath. The standard oath does not require any religious or moral statements, while the expanded oath requires the witness to affirm certain religious or moral values. Both oaths require the witness to swear to tell the truth, the whole truth, and nothing but the truth.
