NRS 136.180: Proof of will by copy.

1. If the will of a person is detained beyond the jurisdiction of the State, in a court of any other state, country or jurisdiction, and cannot be produced for probate in this State, a copy of the will may be admitted to probate in this State in lieu thereof and has the same force and effect as would be required if the original will were produced.

2. Unless otherwise ordered by the court, a subscribing witness may testify in person, by deposition or by affidavit with respect to a copy of the executed will, and with respect to the handwriting of the affiant as a witness, or the handwriting of the testator or another witness, in the same way as he or she would if the original will were available.
