Self-Proving Affidavit for Wills Requirements in Nevada

At a glance

Requirements one by one

Availability and governing law

Nevada's ordinary route is in NRS 133.050, supplemented at probate by §§ 136.150 and 136.160. It is not the usual testator-plus-witnesses acknowledgment block. Instead, an attesting witness supplies the facts that the witness would have to give in court. Nevada separately imposes a qualified-custodian and continuous- custody requirement on a self-proving electronic will under § 133.086.

Who signs or swears

Any attesting witness may sign either a declaration under penalty of perjury or an affidavit. The testator does not have to acknowledge or swear. Although the statutory sample shows two witnesses, subsection 1 says “any attesting witness,” and § 136.150 permits an uncontested will to be proved by one subscribing witness. After death, any or all witnesses may sign at the executor's or any interested person's request.

When it may be made

Section 133.050 does not confine the declaration or affidavit to the execution ceremony. Section 136.160 removes any doubt about the late route: it expressly allows the affidavit after the testator's death. If an affidavit or declaration is attached and signed at the same time as the will, § 133.055 may treat that signature as a will signature when necessary to prove execution.

Officer, oath and seal

The unsworn declaration route uses Nevada's penalty-of-perjury language and needs no oath officer. For an affidavit, the witness may appear before any person authorized to administer oaths in Nevada or elsewhere. The sample uses a notary public, but the operative text is broader and states no separate official- seal requirement.

Required recitals and form

The controlling standard is functional: the witness states the facts that would be required in court to prove the will. Nevada says its affidavit and declaration forms may be followed substantially. Their recitals cover witnessing the execution, the testator's subscription and declaration of the will, the witnesses' later subscriptions in the testator's and each other's presence and at the testator's request, and the testator's apparent full age and sound mind and memory.

Attachment to the will

The declaration or affidavit must be written on the will. If that is impracticable, it may be on paper attached to the will. An electronic statement must be incorporated into, attached to, or logically associated with the electronic will. The same-time signature-spillover rule in § 133.055 applies only to a statement attached to the will and only when the signature is needed to prove execution.

Electronic, remote and out-of-state rules

Section 133.050 expressly anticipates audio-video appearance and requires the form to say when the testator or a signing witness appeared that way. Section 133.088 defines the communication as real-time sight, hearing, and communication and supplies electronic-signature, electronic-record, and electronic- notarization rules for proceedings relating to electronic wills. The validity of an electronic notarial act follows the commissioning jurisdiction's law.

An electronic will is not self-proving from witness statements alone. It must designate a qualified custodian, remain continuously with a qualified custodian before conversion to a certified paper original, and preserve the declarations or affidavits as part of, attached to, or logically associated with the will. Nevada recognizes a qualifying electronic will executed under another state's law, but the cited provisions do not state a blanket rule that every foreign self-proof clause automatically receives Nevada's paper-will shortcut.

Probate effect and exceptions

The statement is accepted as though the witness testified before the court, and a filed affidavit has the same force as oral testimony. Filing the post-death affidavits also avoids routine subpoenas to county-resident witnesses. In an uncontested case, one subscribing witness's proof may be enough.

That is an evidentiary substitute, not an incontestable certificate. Section 136.150's one-witness admission rule applies when no person contests probate. A certified paper original of a self-proving electronic will receives the stronger presumption and expeditious-admission command only “absent any objection.”

If there is no affidavit

The will is not invalid merely because it lacks the declaration or affidavit. If probate is uncontested, one subscribing witness may testify to due execution, sound mind, and age 18. When subscribing witnesses are dead, incapable, or otherwise unavailable, § 136.170 permits in-person, deposition, or affidavit proof from at least two credible disinterested persons that the signature is genuine, or other sufficient signature proof. The court may still require an available subscribing witness or other pertinent evidence.

What trips people up

The testator is not a required affidavit signer

Nevada's sample affidavit describes what the witnesses swear and gives signature lines for the affiants. The governing sentence authorizes “any attesting witness.” Adding the testator may be a drafting choice, but it is not a condition Nevada imposes for witness self-proof.

The electronic-will custody chain is substantive

Logical association of the witness statements is only one part of electronic self-proof. A designated qualified custodian and continuous qualified custody before paper conversion are also required. Without that chain, the electronic will may still be offered through the ordinary proof route, but it does not earn § 133.086 self-proving status.

Common questions

Can a Nevada witness make the affidavit after the testator dies?

Yes. Section 136.160 expressly allows any or all attesting witnesses to do so at the request of the executor or any interested person.

Must a Nevada self-proving statement be notarized?

No. A witness may instead use the statutory declaration under penalty of perjury. If the witness chooses an affidavit, an oath-authorized person in or outside Nevada must take it.
