South Dakota recognizes attested wills, holographic wills, and harmless-error wills

South Dakota Codified Laws — Execution; Witnessed or Notarized Wills; Holographic Wills

S.D. Codified Laws § 29A-2-502

What the rule says

South Dakota provides three pathways to a valid will under the UPC framework:

Attested wills (S.D. Codified Laws § 29A-2-502)

1. A writing. 2. The testator's signature. 3. Two competent witnesses.

Holographic wills (§ 29A-2-502(2))

A SD holographic will is valid if material provisions are in the testator's handwriting and signed.

Harmless-error doctrine (§ 29A-2-503)

Defective documents can be probated with clear and convincing evidence of testamentary intent.

Self-proving affidavits

South Dakota recognizes self-proving affidavits under standard UPC framework.

What you can do about it

For a SD will execution:

- Have the testator and at least two witnesses present. - Use the self-proving affidavit. - Sign at the end of the document. - Avoid using beneficiaries as witnesses.

Who this affects most

South Dakota's flexible three-pathway framework reduces execution risk significantly.
