As long as you don't use your real names, you will remain anonymous.
So, from your original post what I understand is ... you are the father of a child?
Were you ever married to the mother? I am guessing not, but please specify.
Has
paternity testing ever been completed and through that testing, were you established legally as the father?
That is VERY important because if you were not married and no paternity has been established, you (in many states) are not legally the father and have no rights.
Has a
child support order even been established? What state? Where (if you know) is Mom/child now (what state) and what state are you in? Have any court orders ever been done? Any motions in court?
If paternity was never established with any court, I am sorry to tell you the likelihood of any court removing the child from Mom and giving you custody is very unlikely.
But, we really need a much more clear picture from you regarding several factors.
