Nevada Revised Statutes Title 12. Wills and Estates of Deceased Persons § 136.170. Proof of will when subscribing witnesses are unavailable

1. If it appears to the court that a will cannot be proven as otherwise provided by law because one or more or all the subscribing witnesses to the will, at the time the will is offered for probate, are dead or mentally or physically incapable of testifying or otherwise unavailable, the court may admit the will to probate upon the testimony in person, by deposition or by affidavit of at least two credible disinterested persons that the signature to the will is genuine, or upon other sufficient proof that the signature is genuine.

2. The provisions of subsection 1 do not preclude the court, in its discretion, from requiring in addition, the testimony in person, by deposition or by affidavit of any available subscribing witness, or proof of such other pertinent facts and circumstances as the court deems necessary to admit the will to probate.
