Can a signature that is witnessed and/or notarized be a forgery?
Yes. Quite often it can be determined through interviews with the witnesses and notaries that they did not actually see the signature placed on the document. In one case, the witnesses, who were neighbors, waited in the living room while the daughter took the document into the bedroom for the mother to sign. The daughter then returned to the witnesses with the signed document, and assuming the mother had signed it, the witnesses signed the witness lines. The document was a forgery.
