Your question, as phrased, is not a legal question. If you mean what CAN he do, he could file for child custody while everyone remains in Nevada. The rules are complicated, but on the facts you indicate, if your son files an action relating to custody while everyone is here, Nevada will have jurisdiction to hear the case. If the girlfriend returns to Ohio before anyone files anything, Ohio will have jurisdiction to hear the case. of course, in either case, it does not determine who would prevail in such an action, or what order would eventually be entered. For the jurisdictional rules, see "the Basics of Family Law Jurisdiction," and for substantive analysis of how custody cases work in nevada, see the other materials and information posted, all at:
