If your son's father's parental rights have been terminated, he has no legal duty to pay child support. I encourage you to consult with an attorney who practices family law in your area.
I agree with the previous commenter, but if his rights have not been terminated you need to contact an attorney to asset you in making sure the father is included in a petition for child support payable to the child's custodian.
This is not legal advice, this is a general response that is only intended to be an analysis of the question and facts you have presented. This response does not create an attorney-client relationship, I am not your attorney. You must hire me and we must agree in writing to the representation to form an attorney-client relationship. I am only licensed to practice law in Virginia.
