Because to use credible witnesses it must be impossible or very difficult for the borrower to obtain a proper form of ID. That this woman hasn't bothered to go to DMV and update her license (and that she's had this issue before tells me that she's had PLENTY of time to do it) does not qualify as impossible or very difficult. It is EXTREMELY easy to get an updated driver's license after marriage.
Credible witnesses are not *just* another form of ID if there's nothing else available. As a notary instructor you should know this. |
