Nebraska: Self-Proving Affidavit for Wills Requirements

Requirements one by one

Availability and governing law

Nebraska authorizes both simultaneous and later self-proof in Neb. Rev. Stat.
§ 30-2329. Sections 30-2429 and 30-2430 supply the ordinary proof routes and the
express evidentiary effect in formal probate.

Who signs or swears

The testator acknowledges and signs, and both attesting witnesses make
affidavits and sign. The statutory forms use three participant signature lines
and distinguish the testator's acknowledgment from the witnesses' sworn
statements. Nebraska provides no witness-only or substitute post-death route.

When it may be made

The will may be executed, attested, and self-proved in one ceremony. An already
attested will also may be made self-proved “at any time subsequent to its
execution.” The later form still requires the testator and both witnesses, so
it is not a procedure the estate can complete after the testator's death.

Officer, oath and seal

Each acknowledgment and affidavit must be made before an officer authorized to
administer oaths under Nebraska law or the law of the state where execution
occurs. The officer's certificate must be under official seal.

Required recitals and form

The statute says the form and content must be substantially as provided. The
testator declares that the instrument is the will, that the signature was made
willingly or directed by the testator, and that execution was a free and
voluntary act. The form also addresses age, sound mind, constraint, and undue
influence. Each witness swears to the testator's execution facts and that the
witness signed in the testator's presence and hearing.

Attachment to the will

For later self-proof, the officer's sealed certificate must be attached or
annexed to the will. In a contested formal case, the statutory presumptions
arise when the will and the attached or annexed acknowledgment and affidavits
are filed.

Nebraska also gives the signatures in the self-proof ceremony an execution
function: the testator's acknowledgment and the witnesses' affidavits are
sufficient to satisfy § 30-2327's will-signing requirements.

Electronic, remote and out-of-state rules

The cited provisions state no will-specific electronic, remote, or foreign-
self-proof mechanism. They do expressly recognize an officer authorized under
Nebraska law or under the law of the state where execution occurs.

Probate effect and exceptions

In a contested formal proceeding, self-proof conclusively presumes compliance
with the signature requirements. Other execution requirements are presumed but
remain subject to rebuttal, without calling a witness merely to obtain those
presumptions. Proof of fraud or forgery affecting the acknowledgment or
affidavit defeats the stated shortcut.

Self-proof therefore does not make every dispute conclusive. It does not by
itself conclusively resolve capacity, undue influence, fraud outside the
acknowledgment or affidavit, or other substantive contest grounds.

If there is no affidavit

In an unopposed testacy case, the court may act on the pleadings if the statutory
conditions are met. If execution evidence is needed, one attesting witness's
affidavit or testimony is sufficient; if that is unavailable, other evidence or
an affidavit may prove execution.

In a contested case, when execution evidence is necessary, at least one
attesting witness must testify if the witness is within Nebraska, competent,
and able. Otherwise due execution may be proved by other evidence. The absence
of self-proof changes the proof route; § 30-2430 describes it as evidence for an
otherwise attested will, not as a separate validity requirement.

What trips people up

“At any time subsequent” still needs all three people

The later route sounds open-ended, but the statutory form still requires the
testator and both witnesses to act. It cannot be completed after the testator
has died merely because the witnesses remain available.

Only the signatures become conclusive

Section 30-2430 separates signature compliance from the other execution
requirements. Signatures are conclusively presumed; the remaining execution
facts are only rebuttably presumed, and fraud or forgery affecting the
acknowledgment or affidavit removes the shortcut.

Common questions

Does a Nebraska self-proving affidavit need a seal?

Yes. Section 30-2329 requires the officer's certificate to be under official
seal for both the simultaneous and later routes.

What if no witness is available in an unopposed probate?

Section 30-2429 permits execution to be proved by other evidence or affidavit
when an attesting witness's affidavit or testimony is unavailable.
