It does now. However, the child and mother never lived in NV, so if he hadn't messed it up, it might not have.
I haven't checked in NV, but in many states, you can obtain the divorce and set the custody and child support issues aside. Then Mom could have filed for custody in child support in whatever state she lived in if she was a U.S. resident. If not, she'd have to file for CS and/or custody in the Phillipines after Dad got the divorce in NV.
In any event, it's too late for any of that. He's stuck paying whatever NV tells him to pay.
