Well I think he does. And that's b/c his father signing over his rights, is leaving him without a father, whether he is there for him now or not. At least later on he can say my father is so and so, if even if he is not there for him. Having him sign over his rights means that if anyone asks about his dad all he can say is I don't have one, b/c that is how it will be legally. Also there are finances ,if josh god forbids ever gets really sick, his father could be by law ordered to pay half of any of his expenses. With no rights, he can not be obligated to do that. And what if josh goes to a private school one day, that is not cheap. His father could also be ordered by a judge to cover some of those costs in addition to child support. Without a father he may not be able to go. I say he does need to know what happens, b/c it is his life that is being turned upside down. What if josh does want to spend time with his father one day, and goes to him but dewitt tells him that he is not his father. Or what if josh gets married and wants his wife to meet his father, but wait he doesn't have one. Every time I have said father so far in this post, I have mean birth father.
And maybe she will get married so josh will have an adoptive father then, but he still won't have a birth father. And so what if she doesn't get married then he won't have a father at all. I think josh should make the decision, b/c it is his father and his life no one else's.
