Omitted or Pretermitted Children Under Wills in South Dakota

Short answer A South Dakota child born or adopted after a will may receive a share if the will neither mentions nor provides for the child, subject to an outside-transfer exception. A child omitted because the testator believed the child dead is treated as an omitted later child. The share is intestate-equivalent if no child lived at execution; otherwise, when the will benefited then-living children, it comes from those gifts. (S.D. Codified Laws § 29A-2-302.)

Requirements one by one

Child and share

Under § 29A-2-302(a), the ordinary route requires a child born or adopted after execution and neither mentioned nor provided for in the will. Subsection (b) treats a child omitted because the testator believed the child dead as an omitted later child. If no child lived at execution, the starting value is an intestate-equivalent share. Where the will gave property to then-living children, the later child's pool is those gifts, equalized as if the omitted later children had been included.

Property used

Earlier children's gifts abate ratably under § 29A-2-302(a)(2)(iv), preserving the testamentary plan as far as possible. In the no-child route, § 29A-3-902 ordinarily uses undisposed property first, then residuary gifts, property not specifically devised, and other property; contrary will intent can change the order.

What trips people up

The other-parent exception applies to the no-child route and requires that parent to survive and be entitled to take an all-or-substantially-all devise. Separately, an outside transfer disqualifies a child only if its intended role as a replacement for a will provision is shown under § 29A-2-302(a)(3). The ordinary entry test says neither mentioned nor provided for; the section has no separate intentional-omission exception.

Common questions

Does an outside gift automatically cancel the share? No. The in-lieu intent must be shown by the testator's statements or reasonably inferred from the transfer's amount or other evidence (§ 29A-2-302(a)(3)).

Can the share be a future trust interest? Under § 29A-2-302(a)(2)(iii), it should match the equitable or legal, present or future character of earlier child gifts where feasible.
