=========================================================== You aren't going to get away with it. A judge simply isn't going to let you represent your wife in the divorce. MAJOR CONFLICT OF INTEREST there ===========================================================
Who's to say what her "interest" is? It could be in her interest to simply get out of the marriage, with whatever she presently has, and to avoid courts and lawyers.
If she is willing to sign such a power of attorney, before a notary, then to the best of my knowledge the judge is required, by law, to approve the divorce. No "attorney ad-litum" would be required, to "protect her interests", as her original, genuine attorney-in-fact (myself) is standing in front of the court!
