First, I don't think he has a loophole because a tax return is not identified as child support. As we know, it is a return when you have paid too much in during the year and your deductions help out...it's not child support by any means. I would check this out w/your lawyer.
There are two ways of checking for tax refunds...if he has your SSN he can call the IRS and inquire as to when your refund was due to be paid and the amount. I've inquired on my own a few years ago.
But, I would venture to say that he's watching your online account. Is this a joint account in both names? If it is your own, individual account, you can remove his name and place another name there if you so choose. I don't believe you need to have him sign off on your request...check w/your bank and explain the situation to the bank manager. They will advise you how best to take care of this. Then change your password as soon as possible.
Your h is doing the same gnat crap mine did and even though he says he's not doing things, he is and you are finding out about them little by little. Do not trust him by any means.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
