South Dakota Intestate Succession: Essential Guide For Heirs
Understand how South Dakota distributes your estate if you die without a will, protecting spouses, children, and family.
When someone passes away in South Dakota without a valid will, state laws determine how their estate is divided among heirs. This process, known as intestate succession, prioritizes close family members like spouses and children to ensure fair distribution of probate assets.
Understanding Probate vs. Non-Probate Assets
Not all property falls under intestate rules. Only assets requiring probate—those solely in the deceased’s name without beneficiary designations or co-ownership—follow these laws. Common non-probate items include joint tenancy real estate, life insurance with named beneficiaries, retirement accounts like IRAs or 401(k)s, and payable-on-death bank accounts. These transfer directly to co-owners or beneficiaries, bypassing probate and intestate succession.
If a beneficiary predeceases the owner without alternatives named, the asset may enter probate and follow intestate rules. South Dakota residents should review titles and designations to control asset flow independently of intestacy.
Spousal Inheritance Rights in Intestacy
A surviving spouse’s share hinges on surviving descendants (children, grandchildren, great-grandchildren) and their parentage. If no descendants exist, or all are shared with the spouse, the spouse receives 100% of the intestate estate.
However, if descendants from prior relationships survive, the spouse gets the first $100,000 plus half the remainder. Descendants split the rest. This protects blended families while honoring the current marriage.
| Family Scenario | Spouse’s Share | Other Heirs’ Share |
|---|---|---|
| No descendants | Entire estate | None |
| Descendants only with spouse | Entire estate | None |
| Descendants from prior relationship(s) | First $100,000 + ½ balance | Remaining ½ to descendants |
Example: Maria dies intestate with $250,000 in probate assets, survived by husband Tom and two kids from a previous marriage. Tom inherits $100,000 + ½ of $150,000 ($75,000) = $175,000. Kids share $75,000 equally.

Children’s Shares Under Intestate Laws
Children inherit equally if no spouse claims the full estate. In per stirpes distribution, a deceased child’s share passes to their descendants. Adopted children count equally; stepchildren do not unless legally adopted.
Posthumous children born within 10 months inherit if viable. Half-blood siblings share equally with full-blood. Heirs must survive the decedent by 120 hours (5 days) to qualify, preventing simultaneous-death complications.
Inheritance for Parents and Siblings
Without spouse or descendants, parents inherit equally. If parents predecease, siblings (or their descendants) take equal shares. Grandparents, aunts/uncles, cousins follow in line before escheat.
| No Closer Relatives | Who Inherits |
|---|---|
| Spouse or descendants | Parents (equal shares) |
| Parents gone | Siblings or their issue |
| No siblings | Grandparents, aunts/uncles, cousins |
| Truly alone | State of South Dakota (escheat) |
Escheat is rare; laws trace remote kin.
Who Qualifies as a Legal Heir?
South Dakota presumes paternity for a man’s child if married to the mother at birth or if he openly treated the child as his own with evidence. Paternity suits may arise in probate. Unwed mothers’ children inherit maternally without issue.
Immigration status doesn’t bar inheritance. Half-relatives treated same as full. Divorces revoke spousal/beneficiary claims unless waived. Homicide bars killers from inheriting.
Key Procedural Rules in Intestacy
- 120-Hour Survival: Heirs must outlive decedent by 120 hours.
- Advancements: Lifetime gifts count against shares if intended as such.
- Debts: Paid from estate before distribution; debtor heirs may offset.
- Disclaimers: Heirs can renounce shares, passing to next in line.
Homestead, Exempt, and Allowance Protections
Beyond shares, spouses/minor children get homestead up to $170,000 (adjustable), exempt property ($20,000 household goods, etc.), and family allowance during probate. These are absolute rights.
Why Draft a Will? Risks of Intestacy
Intestate laws may mismatch wishes, especially in blended families or with non-relatives (friends, charities). Legislative changes can alter distributions. Wills, trusts, and designations offer control, avoid probate delays (6-18 months), and reduce costs.
Consult attorneys for TOD deeds, revocable trusts to bypass probate entirely.
