I'm very sorry to hear of your dilemma.
Unfortunately, when you gave your wife the Power of Attorney that was so broad as to allow her to take out mortgages in your name, you were just asking for trouble. However, apparently that is what you did.
I'm not sure what you mean by active loan date. However, look at all the documentation. If she did not sign your signature on any loan documentation until AFTER the moment that she had the the POA, it doesn't matter when she began looking to fund the loan.
So long as the POA was not violated, and the financial transaction made was, arguably, to your benefit--which arguably it was--there is not a thing that you can do about it.
I presume that your present attorney is a private attorney. There is no reason that she should not be handling this, unless she is incompetent to handle any other area of law except family law
--in which case you should fire her and get a more well rounded attorney to assist you.
I wish you the best.
