Self-Proving Affidavit for Wills Requirements in Minnesota

At a glance

Requirements one by one

Availability and governing law

Section 524.2-504 provides two routes. A will may be executed, attested, and made self-proved in one ceremony, or an already-attested will may receive the acknowledgment and affidavits later.

Under § 524.1-201(17), an electronic will is defined, and § 524.1-201(62) includes it within "will," and the special definitions for §§ 524.2-501 through 524.2-517 include electronic signatures, electronic writings, and audiovisual presence. The general self-proof section therefore is not limited to a paper will.

Who signs or swears

The testator acknowledges the will and signs a sworn declaration. The two witnesses shown in each statutory form sign sworn affidavits. The officer's certificate records the testator's subscription, oath, and acknowledgment and the witnesses' subscriptions and oaths.

Section 524.2-504 supplies no attorney-certification substitute and no person who may complete the testator's part after death.

When it may be made

The one-step route is contemporaneous with execution and attestation. Under subsection (b), an attested will may be made self-proved "at any time after" execution. The statute sets no elapsed-time limit, but the later form still requires the testator and witnesses to participate.

Officer, oath and seal

For the one-step route, the officer must be authorized to administer oaths by the state where execution occurs. For the later route, the officer's authority comes from the state where the acknowledgment occurs. Both routes require the officer's certificate under official seal.

A Minnesota remote online notary must be physically located in Minnesota. The remote certificate must contain the electronic signature and seal, identify the remote appearance, and otherwise conform to state law.

Required recitals and form

The forms require substantial rather than word-for-word compliance. The testator identifies the instrument as the will, states that the signature or direction to another signer was willing, and declares a free and voluntary act, age of at least 18, sound mind, and freedom from constraint or undue influence.

The witnesses swear to the execution facts, including willing signature or direction, signing in the testator's presence and hearing, and the testator's age, sound mind, and freedom from constraint or undue influence.

Attachment to the will

For later self-proof, the officer's sealed certificate must be attached or annexed to the will. A signature on an attached self-proving affidavit counts as a signature on the will if needed to prove due execution.

If an electronic will is self-proved, § 524.2-518 requires a certified paper copy to include the self-proving affidavits. The certified copy may substitute when chapter 524 requires an original will.

Electronic, remote and out-of-state rules

Minnesota recognizes electronic wills, electronic signatures logically associated with the writing, and audiovisual presence between the testator and will witnesses. A compliant remote online notarial act also satisfies a state law requiring appearance before or presence with a notary.

The Minnesota remote notary must remain physically in Minnesota. A signer may be elsewhere in the United States, and the statute provides additional conditions for a signer outside the United States.

Section 524.2-504 lets officer authority come from the relevant state of execution or acknowledgment. Section 524.2-506 separately recognizes some wills executed under another place's law, but the cited provisions do not say that foreign self-proved status alone carries into Minnesota.

Probate effect and exceptions

In a contested case, filing the self-proved will with its attached or annexed acknowledgment and affidavits conclusively presumes compliance with the signature requirements. Other execution requirements are presumed subject to rebuttal, without testimony from a witness.

Proof of fraud or forgery affecting the acknowledgment or affidavit defeats those self-proof presumptions. The statute does not turn the affidavit into a bar against a contest.

If there is no affidavit

In informal probate, a will with the apparent required signatures and a proper attestation clause may be probated without further proof. Otherwise, the registrar may assume execution from an apparently proper will or accept a sworn statement or affidavit from anyone who knows the execution circumstances.

If execution evidence is necessary in a contested case, at least one attesting witness must testify when that person is in Minnesota, competent, and able to testify. Other evidence remains available, including a witness affidavit, and a signed attestation clause creates a rebuttable presumption of its recited events.

What trips people up

An attestation clause and a self-proving affidavit are different

A qualifying attestation clause can permit informal probate without further proof under § 524.3-303(c). It does not produce § 524.3-406(b)'s split contested- case presumptions: conclusive for signatures and rebuttable for the other execution requirements.

Electronic execution does not erase the oath certificate

Electronic signatures and audiovisual presence are recognized, but self-proof still requires the testator's acknowledgment, the witnesses' affidavits, and an oath officer's sealed certificate. A remote online certificate must also state that the appearance occurred remotely.

Common questions

Can a Minnesota will be made self-proving years after signing?

Yes. Section 524.2-504(b) says an attested will may be made self-proved "at any time after" execution, provided the testator and witnesses can complete the required sworn form before the officer.

Can the self-proving ceremony be completed remotely?

Minnesota's remote-online-notary law says a compliant remote act satisfies a state-law requirement that a notarial act occur in the notary's presence. The remote notary must be physically in Minnesota, the certificate must identify the remote appearance, and the other self-proof requirements still apply.

What becomes conclusive when the will is self-proved?

Compliance with the signature requirements. Other execution requirements are only rebuttably presumed, and fraud or forgery affecting the acknowledgment or affidavit defeats the shortcut.

Is a will without the affidavit invalid?

No. Minnesota supplies ordinary proof routes, including an attestation clause in informal probate, testimony when needed in a contested case, witness affidavits, and other evidence.
