How many witnesses does a will need in South Dakota?

A will in South Dakota must be signed in front of two witnesses. The witnesses do not need to be present together when they sign, but each must witness the testator's signature or acknowledgment. See S.D. Codified Laws §29A-2-501 et seq..

Does a will have to be notarized in South Dakota?

No. Notarization is not required for a South Dakota will to be valid, but adding a self-proving affidavit (which is notarized) lets the will be admitted to probate without calling the witnesses to testify.

Is a handwritten will valid in South Dakota?

Yes. South Dakota recognizes holographic wills (wills written entirely in the testator's handwriting and signed by the testator) without witnesses. We do not generate handwritten wills, but you may write one by hand if you prefer.

What is the minimum age to make a will in South Dakota?

You must be at least 18 years old to make a will in South Dakota.

Can I sign my will online in South Dakota?

No. South Dakota does not currently recognize electronic wills. A will must be signed and witnessed in person on paper to be valid; remote online notarization is allowed for other documents like trusts and powers of attorney.

Will

S.D. Codified Laws §29A-2-501 et seq.

Witnesses: 2 required

Two witnesses must sign in the conscious presence of the testator after witnessing either the signing of the will or the testator's acknowledgment of that signature. Showing witnesses a will already signed in private is not enough, because South Dakota did not enact the alternative trigger of acknowledging the will itself. Witnesses may appear in the testator's electronic presence for a non-holographic will (SDCL §18-8-2, SL 2022, ch 56). SDCL §29A-2-502(b)(3)

Notarization: Recommended

Not legally required, but recommended for self-proving affidavit

Holographic will: Valid

Handwritten wills without witnesses are recognized in South Dakota

Self-proving affidavit: Available

Allows the will to be admitted to probate without witness testimony

ViewWitness disqualification / interested-witness rule

SDCL §29A-2-505 (the signing of a will by an interested witness does not invalidate the will or any provision of it; South Dakota has no purging-of-gifts rule)

Living Trust

Witnesses: None required

No formal execution requirements beyond settlor signature; notarization strongly recommended when funding real property

Notarization: Recommended

Not legally required for the trust document, but needed to transfer real property

Durable Power of Attorney

Witnesses: None required

No witnesses required for power of attorney

Notarization: Required

Notarization is required for a valid durable power of attorney

State-specific notes

•Acknowledged before a notary public or other individual authorized by law to take acknowledgments. SDCL §59-12-4

•Durability is NOT presumed under South Dakota law. A power of attorney terminates on the principal's incapacity unless the instrument contains express durability language such as 'This power of attorney shall not be affected by disability of the principal,' 'This power of attorney shall become effective upon the disability of the principal,' or similar words showing the principal's intent that the authority is exercisable notwithstanding disability. SDCL §59-12-3

•A spouse-agent's authority terminates on the filing of an action for divorce, annulment, legal separation, or a protection order between the principal and the agent, unless the power of attorney provides otherwise. SDCL §59-12-9(2)(c)

Living Will Declaration

SDCL §59-7-2.1 (Durable Power of Attorney for Health Care); SDCL §34-12D-1 et seq. (Living Will Declaration), sample form at SDCL §34-12D-3

Last verified: 2026-08

Witnesses: 2 required, or notary

South Dakota accepts either 2 witnesses or notarization

Notarization: Accepted as alternative

Either two adult witnesses or notarization by a notary public satisfies execution, and the same either-or rule governs both halves of the directive (SDCL §59-7-2.1 for the Durable Power of Attorney for Health Care, and SDCL §34-12D-2 for the Living Will Declaration, as amended by 2023 SD Sess. Laws ch. 115, §1)

State-specific notes

•Execution requires either two adult witnesses or notarization by a notary public; either method is valid. The 2023 amendment (SDCL §34-12D-2, Senate Bill 180, ch. 115) replaced the prior witnesses-mandatory-plus-optional-notary rule with this either-or framework.

•The statutory Living Will Declaration form pre-dates its own execution rule. The form still carries signature lines for you, two witnesses and a notary public, and its own instructions describe all three (SDCL §34-12D-3, last amended by SL 2007, ch 193). Treat that as belt-and-braces rather than a requirement: since the 2023 amendment, either two adult witnesses or a notary is enough (SDCL §34-12D-2).

•Witnesses may appear in the declarant's electronic presence. SDCL §18-8-3

ViewWitness disqualification recital

Neither South Dakota section governing this directive disqualifies anyone from serving as a witness. SDCL §59-7-2.1 requires only that the principal's signature be witnessed by two other adult individuals or by a notary public, and SDCL §34-12D-2 requires only that the living will declaration be signed by the declarant, or by another at the declarant's direction, and witnessed by two adults or by a notary public who then notarizes it. Neither section bars a relative, an heir or devisee, the attending physician, an employee of the principal's health care provider or facility, or a person financially responsible for the principal's care. Because §59-7-2.1 calls for two other adult individuals, the witnesses must be persons other than the principal and other than anyone who signs the principal's name at the principal's direction. Two disinterested adults remain sound practice, because a witness with no stake in the outcome is harder to challenge, but South Dakota does not require it.

Electronic will status

South Dakota has not adopted electronic will legislation. A traditional paper will with physical signatures is required.

Digital assets access

South Dakota has adopted RUFADAA (2017). This is the Revised Uniform Fiduciary Access to Digital Assets Act, which lets your executor, trustee, or agent access your email, social media, cryptocurrency wallets, cloud storage, and other digital accounts after death or incapacity.

To take advantage of RUFADAA, your will, trust, or power of attorney must explicitly grant authority to access digital assets. Without explicit authorization, service providers can deny access even to a court-appointed executor.

Remote online notarization (RON)

South Dakota authorized RON in 2019. South Dakota does not use notarization to execute a will, so a will cannot be remotely notarized into existence. The separate self-proving affidavit is a notarial act (SDCL §29A-2-504), and a South Dakota notary located in South Dakota may perform that act on the paper affidavit while you appear by video, but only where the notary already has personal knowledge of your identity from prior dealings (SDCL §18-1-11.1). Identity proofing as a substitute for the notary knowing you is authorized only for notarial acts on electronic records (SDCL §18-1-11.2), not for paper. If your notary does not already know you, plan to appear in person.

Remote online witnessing (ROW)

South Dakota allows remote online witnessing for some estate planning documents. Witnesses can observe your signing over a live video call instead of being physically present. The 2022 SD remote-witnessing package (SL 2022, ch 56) is broader than wills alone: SDCL §18-8-2 (sec. 2 of ch. 56) covers non-holographic wills; SDCL §18-8-3 (sec. 3) covers SDCL §34-12D-2 living will declarations; SDCL §18-8-4 (sec. 4) covers SDCL §59-7-2.1 durable health care powers of attorney, witnessed by two other adult individuals in the principal's electronic presence; SDCL §18-8-5 (sec. 5) covers anatomical gifts and refusals under SDCL §34-26-52(b) and SDCL §34-26-54(b) with the additional requirement that at least one of the two witnesses be disinterested. Definitions in SDCL §18-8-1.
