Generally, the only reason to file a prenup with a court would be if the spouses are seeking a divorce, so I really don't know what the last part of your first question means. Beyond that, it is impossible to say, in the abstract, how a move from one state to another might impact a prenup. One would need to read the prenup and know all of the relevant facts and circumstances. If your intent was to ask whether a move to a different state automatically renders a prenup void or unenforceable, the answer is no.
