He wants to sign his rights away
No, he can't. There has to be a court order. Judges are reluctant to do this unless there is an adoption in the offing. The concern is that the parents whose rights have been terminated will then not have to pay child support and the child will then file for public benefits of one sort or another. I suggest you discuss this with a family law practitioner.
