Lawyer to fight corrupt FRO

I have paid up until he was 18 and something. He had is won child ay 17.5 years old and lived with the girl. His mother has kept this going for 10 years. I know have lost my license insurance and passport. because se failed to info legally that he dropped out of high school had his own kid and didn't live at home. Now I have to defend myself while she has to do nothing. This is criminal . I don't have 5k for a lawyer. So o have lost everything. She stopes them from seeing me in 2012ish. I have not seen or talked to him in 9-10 years. I owe 25k from back when she should have stopped it. I would like to fight her and sue her for the over payment and the fees to get my license back and passport. She needs to feel the pain of all this and understand this is wrong and you cant do this to people unjustly. She needs to know there is consequence for lying on legally docs and hurting people deliberately just for money monthly. There is so much more she did with the affairs while I worked 18 years and she never worked. Collecting cash and abusing mothers allowance. And there is so much more. I need help I want to bring the hammer down on her for all this. I have for the last 10 years of not seeing my family as soon as fro was involved have struggled mentally to even care about waking up. I want her to feel the justice.
