No answer to your question but two things come to mind. 1) Can you fix your financial statements to show the reality ? If you can show that the ex's atty manipulated them he could be liable. 2) Keep the custody separate if you can. Get the custody order from the court that you have primary custody as everyone appears to believe.
I have no faith in the legal system after my experiences so I hear you loud and clear.
The OC is not manipulating my financial statements as in "changing numbers". He's doing stuff like attributing the expense of 4 delivery vehicles as if they were all a personal benefit to me. Plus many more sneaky little tricks.
I think they should be liable. I've been completely straight forward with my finances from the beginning. My company is a young startup and there's no money in it so I figured there would be nothing for lawyers to come after me for... . boy was I wrong. Now I understand why everyone hates lawyers. If the OC and his forensic hadn't been so sneaky (I'm not listing all of their tricks to keep this brief) I wouldn't have had to spend in the neighbourhood of $30,000 just trying to prove I don't have any money.
There has to be something I can do. This is wrong from every angle.
