You listen very carefully to what your wife has to say because she is your wife and that will have an effect on your marriage. But you make legal decisions based on expert legal advice from an attorney. I recommend you discuss the decision with your wife so she is part of the decision making process.
It might be nice that your wife is giving you legal advice, but if she isn't a lawyer the advice is not useful. If you need legal advice, consult a lawyer with a degree who has passed the bar in your state.
