EX#3's EX and he had an appeal sitting with the NV supreme court for a few years (sorry, but yes, it took THAT long). Meanwhile she did as she pleased on several different subjects. Once he brought the appeal back to the local court (geez, THAT alone took 6 months), had something heard locally (denied), had it sent back to the Supreme court.
I'm no attorney -- but base my answers on experience.
