A notarizing officer having taken an acknowledgment of an instrument and made a certificate of that fact cannot afterwards amend or change his certificate for the purpose of correcting a mistake. This can be done only by the parties reacknowledging the instrument. However, typographical errors may be corrected by striking out the erroneous characters and inserting the correct ones above. Such changes should be initiated by the parties who executed the instrument and by the notarizing officer.
