Nev. Rev. Stat. § 15.010

1. In all cases of the verification of a pleading, the affidavit of the party shall state that the same is true of the party’s own knowledge, except as to the matters which are therein stated on the party’s information and belief, and as to those matters that the party believes it to be true. And where a pleading is verified, it shall be by the affidavit of the party, unless the party is absent from the county where the attorneys reside, or from some cause unable to verify it, or the facts are within the knowledge of the party’s attorney or other person verifying the same.

2. When the pleading is verified by the attorney, or any other person except the party, the attorney or other person shall set forth in the affidavit the reasons why it is not made by the party.

3. When a corporation is a party, the verification may be made by any officer thereof; or when the State, or any officer thereof in its behalf, is a party, the verification may be made by any person acquainted with the facts; except that in actions prosecuted by the Attorney General, in behalf of the State, the pleadings need not, in any case, be verified.

4. In all cases where, by the foregoing provisions, the verification may be made by the attorney, such verification may be by the attorney made on information and belief if the facts are not within the attorney’s knowledge.

5. The affidavit may be in substantially the following form and need not be subscribed before a notary public: Under penalties of perjury, the undersigned declares that he or she is the ________________________________ (plaintiff, defendant) named in the foregoing ________________________________ (complaint, answer) and knows the contents thereof; that the pleading is true of his or her own knowledge, except as to those matters stated on information and belief, and that as to such matters he or she believes it to be true. _________________________________________________
