Before reading further, note that I am not an attorney.
One question might shed a little light on your quandary, although I suspect you had to make your decision already. Against whom is the court order directed? Better put, does the court direct that the bank not allow withdrawals, or is the order phrased such that the son/attorney not remove the funds from the guardianship accounts?
