I think what OP needs are good resources so that he can educate himself as much as possible. Yeah he also needs a lawyer, if this is that important to him, but being informed will be a force multiplier here.
in my experience people are generally shity when you ask for legal advice online but you could try that. For example stack exchange has one but you'll probably get condemned on there instead of getting helpful advice.
An out-of-the-box idea might be to find a paralegal on FIVERR and ask them to dig up resources to read up on.
Again I apologize for being such a jerk about your suggestion. I'm a terrible person.
