Answer:
There's not a black and white answer to this question. If the wife has been signing her husband's name to his checks for a long time, and he hasn't raised a fuss, he may have ratified her actions. If he benefited from the payments his wife made from his account, he can't press a forgery or fraud case very far, either. Even if the wife was paying one of her own obligations without her husband's permission to sign his name, the "repeat wrongdoer" rule in 4-406 of the UCC would limit the bank's exposure.
