This is unclear. Was this a joint account? Is that how she got funds out of it? Your complaint is that you didn't give her permission? Or is this account in your name only and she forged your signature to get the money? If she forged your signature, I suppose you could have her arrested and prosecuted, if that is the kind of marriage you have/want. Is total control that important to you? If you don't want her prosecuted, then it sounds like you have a normal marriage where a wife can have equal access to the marital community's funds to fill household needs. It sounds like you have other ideas of how a marriage ought to be. Can't help you with that.
Is this a question about identity theft? It's not what the legal problem is here.
