Well if he has to file for it, then you shouldn't have to worry about beating him to it. Just let it ride and deal with it if it comes up. Just see if anyone is willing to testify on your behalf that he hasn't been around ever and has contributed nothing to the baby and even denied paternity of the child, so he has nothing to offer this child. I'm sure you'll at least be awarded custody. He might still be eligible for visitation, but a lot of guys seem to "forget" to show up on their days.
Especially the deadbeat variety.
