The kid wanted to see Nux and that's the only way. Thanks to that Nux found out about the kid. Asperier (the main body) suffers from post-partum depression and doesn't want Nux to know about the kid by the time he found out about the lawsuit fuled by his kid, Nux already knew about it. Nux, originally wanted to give up his parenting rights because he knew that he will never win the lawsuit against Owen but when the court wants to hear his answer he said that he will appeal for his rights to kid.
So he travel, far and wide using the space ship that Owen gave him. While travelling, he met the other two Owen (aside from the 2 Owen he met when his in college) they helped him to reach the kid.
Nux can't enter the planet for Asangards because he is an earthling but due to the lawsuit (and with the help of the kid because apparently Asangards higher ups valued and gave more importance to the needs of the children in their planet especially since the kid of Owen is more special because it was born and created naturally) when meeting with the kid, Nux didn't saw Asperier (coz he's hiding from him, afraid that Nux will hate him once he saw his "ugly" face but don't worry he is not ugly its just his depression talking).
FF, Nux confronted Owen and they reconcile though and eventually got married all SIX of them. That's the rule, Nux have to marry all of Owen's body so yeah it's a happy ending.
