Wife lies about credit card debt and then what?

Wife withdrew $20K credit card advance and hide the fact from Husband.  After the court heard all of the facts it made some rulings and did not sanction wife for her breach of Fiduciary Duties, although the court did find that wife did breach her duty.  The Appellant court held that the sanction was mandatory and remanded to the lower court to set the penalty against wife.  The moral of the story is that everyone who is married has a duty to be fair in their dealings with the other spouse during marriage and thereafter.
