Thank you for your question. I look forward to working with you to provide you the information you are seeking for educational purposes only.
In Louisiana, parental rights and child support are separate issues. This means that signing away parental rights does not absolve a party of their obligation legally to provide child support, so he could sign away his rights and still have to pay support. Even if he tries to get a signed agreement from the mother waiving rights to child support in exchange for him terminating his parental rights, if the court finds that the child needs care and the mom cannot provide that care, then the court could void that agreement as unconscionable and not in the best interests of the child.
Thus, you need to contact a local attorney and get him representation to deal with negotiating and getting approved by a court an agreement where he terminates rights to try to protect him at least with a minimum support payment.
