If my wife get divorced and we get split custody, can ex move out of state with my daughter without my permission?

Short answer: no.

In short, no. However, this is somewhat of a gray area under Nevada law right now and pending before our Supreme Court as well as in the legislature. Best bet is to have an attorney do your papers and add in any special protective language that may be necessary such as a restriction on either parent moving more than 10 miles away from their present location so as to ensure the split custody schedule will work. Remember, Nevada is a very large state and one could move within the state and still be very far away.
