In Nevada, there is no “magic” age where children get to decide which parent they want to live with. The custodial preference of a minor child is just one factor of many under the “best interest of the child” statute NRS Chapter 125C (http://www.leg.state.nv.us/Nrs/NRS-125C.html#NRS125CSec0035). Depending on the age of your child(ren), you may request to allow your child to testify.
