The Pennsylvania Oath of Witness to Will Executed By Another is a legal document that is used to confirm that a witness has seen a testator sign a will in the presence of two witnesses and a notary public. This document is used to attest to the fact that the testator was of sound mind, knew the content of the will, and willingly signed it. There are two types of Pennsylvania Oath of Witness to Will Executed By Another: the general form and the special form. The general form is used when an individual is signing a will as a witness and the special form is used when a notary public is witnessing the signing of a will. Both forms require the witness to swear or affirm that the testator was of sound mind and willingly signed the will. The witness must also confirm that the testator was aware of the contents of the will before signing it.
