You've painted a complicated picture that is probably more complicated than stated. Assuming a valid cause of action exists that isn't time barred, you will have a difficult time finding an attorney to take such a case, certainly not on a contingency basis. Find a good family law attorney regarding the custody issue and go from there.

I don't know if you have an actionable claim against anyone based on your question. But moving forward, you should get right with child support, get a custody lawyer to fight for you, and get back in your child's life in a positive way. Good luck.
There is no valid basis for you to bring a claim for "pain and suffering" because of what has happened to you based upon prior and/or pending legal actions and court orders issued as a result thereof. Similarly, you can not make a claim that your son was damaged psychologically by the prior history you describe for numerous and complex reasons that would be too lengthy to go into here. Furthermore, to bring a claim in behalf of your son would require a Legal Guardian to act for him in the lawsuit as he is a minor and minors can not bring lawsuits solely in their own name. You do not have custody and it is highly doubtful that your ex would agree to the bringing of such a claim, let alone allow you to do so.
