Unfortunately, it is illegal, in fact a federal felony bank fraud to open a credit card account in anyone's name, even if permission is given by the person who's information is used on the application and if a person uses a credit card that was issued to another person, that can constitute federal felony credit card fraud, which is a very serious federal felony crime punishable by up to 5 years in prison, fine of up to $250,000 and also a criminal restitution upon conviction.
So with that said and given the seriousness of the situation and potential felony charge, it is important not to discuss the matter with anyone and to consult and retain an experienced local criminal defense attorney and to let this local attorney handle any and all communications with husband, authorities, police, etc...since anything that a suspect says herself, can and will be used against her if criminal charges are filed.

When, choosing a local attorney to represent you, it would be a good idea to choose someone who has a practice exclusively dedicated to criminal law, has at least 10 years of experience and handled similar matters and also regularly practices before the court located in the jurisdiction where your matter might be heard.
