Who Inherits When There Is No Will in South Dakota
Here is exactly how South Dakota divides an estate when there is no will:
| If the person leaves… | Who inherits in South Dakota |
|---|---|
| Spouse, no children | The surviving spouse inherits the entire intestate estate under SDCL 29A-2-102. This applies regardless of whether the decedent’s parents are still living. South Dakota does not reduce the spouse’s share when parents survive but no descendants exist. |
| Spouse + shared children | The surviving spouse inherits the entire intestate estate under SDCL 29A-2-102. When all of the decedent’s surviving descendants are also descendants of the surviving spouse, the spouse takes everything. The children inherit nothing through intestacy in this scenario (though they may inherit from the surviving spouse’s estate later). |
| Spouse + children from another relationship | The surviving spouse inherits the first 100000 of the intestate estate, plus one-half of the remaining balance, under SDCL 29A-2-102. The decedent’s descendants (children from another relationship) inherit the other half of the balance beyond 100000. If the estate is worth 100000 or less, the spouse takes everything and the descendants receive nothing from intestacy. |
| Children, no spouse | The children (descendants) inherit the entire intestate estate, divided by representation under SDCL 29A-2-103(1). If a child predeceased the decedent but left surviving descendants, those grandchildren take the deceased child’s share by representation under SDCL 29A-2-106. |
| No spouse, no children | Under SDCL 29A-2-103, the estate passes in this order: (1) to the decedent’s parents equally, or to the surviving parent if only one is alive; (2) if no parent survives, to the descendants of the decedent’s parents (siblings, nieces, nephews) by representation; (3) if no parent or descendant of a parent survives, half the estate goes to paternal grandparents (or their descendants by representation) and half to maternal grandparents (or their descendants by representation); (4) if there are no surviving relatives on one side, the entire estate passes to relatives on the other side. |
| No living relatives (escheat) | Under SDCL 29A-2-105, if there is no taker under the intestate succession provisions, the intestate estate escheats to the State of South Dakota. This is rare because the statute reaches broadly to grandparents and their descendants (aunts, uncles, cousins) on both sides before escheat applies. |
These shares come from South Dakota intestate-succession law (SDCL 29A-2-102 (spouse’s share), 29A-2-103 (heirs other than surviving spouse), 29A-2-105 (no taker), 29A-2-106 (representation), 29A-2-107 (half blood)).
How South Dakota divides shares among descendants: South Dakota uses distribution “by representation” under SDCL 29A-2-106. The estate is divided into as many equal shares as there are surviving members of the nearest generation with living members, plus deceased members of that generation who left surviving descendants. Each surviving member takes one share, and the share of each deceased member is subdivided in the same manner among that person’s descendants.
This is sometimes called “per capita at each generation.”
South Dakota homestead and family allowance: Under SDCL 29A-2-402, the surviving spouse or minor children are entitled to a homestead allowance as provided in SDCL chapter 43-31 (homestead is exempt from judicial sale and judgment liens). Under SDCL 29A-2-403, the surviving spouse is entitled to a reasonable family allowance for maintenance during estate administration, up to 18000 as a lump sum or 1500 per month for one year.
These allowances have priority over all claims against the estate and are in addition to any share passing by will, intestate succession, or elective share. The surviving spouse also has a right to occupy the homestead. An heir must survive the decedent by 120 hours under SDCL 29A-2-104 to qualify for homestead allowance, exempt property, and intestate succession.

Half-blood relatives in South Dakota: Under SDCL 29A-2-107, relatives of the half blood inherit the same share they would inherit if they were of the whole blood. A half-sibling is treated identically to a full sibling for intestate succession purposes.
Assets That Pass Outside South Dakota Intestate Rules
Assets with named beneficiaries (life insurance, retirement accounts, payable-on-death bank accounts), property held in joint tenancy with right of survivorship, and assets held in a living trust pass outside South Dakota’s intestate succession rules and are not governed by SDCL 29A-2-102 through 29A-2-103. Only assets in the decedent’s individual name with no beneficiary designation pass through intestacy.
Other South Dakota intestacy rules: South Dakota adopted the Uniform Probate Code (Title 29A). A person must survive the decedent by 120 hours (5 days) to inherit under intestate succession (SDCL 29A-2-104). Legally adopted children inherit the same as biological children (SDCL 29A-2-114). South Dakota has no state estate tax or inheritance tax.
The surviving spouse also has a right to an elective share of the augmented estate under SDCL 29A-2-202, which must be elected within 9 months after the decedent’s death or 4 months after the will is admitted to probate, whichever is later.
What Dying Without a Will in South Dakota Really Means
When someone dies without a will in South Dakota, the state’s intestate-succession law — not the family — decides who inherits. The shares above show exactly how South Dakota divides an estate when someone is dying without a will in South Dakota, and they often surprise people: a spouse may not automatically inherit everything.
Understanding dying without a will in South Dakota helps a family know what to expect before they walk into probate court. Remember that some assets pass outside these rules entirely, so the full picture of dying without a will in South Dakota depends on how each asset was titled.
