He can't "sign off his rights". Protective services would have to conduct an investigation, after receiving a complaint of abuse and neglect to see if there is conduct warranting court intervention, and possibly termination of parental rights. From your statement's, his conduct does not rise to that level. If he hasn't seen the child and does not care to, then don't worry about it.
