South Dakota Surviving Spouse Rights in Probate

If your spouse died and left a will that doesn't provide for you the way you expected — or left everything to someone else — South Dakota law gives you specific legal protections that override the will in certain situations. These aren't optional courtesies. They're statutory rights that a surviving spouse can claim regardless of what the will says, and they can significantly affect how the estate is distributed.

Here's what South Dakota law provides for surviving spouses in probate.

The Elective Share: Your Right Against the Will

South Dakota's elective share allows a surviving spouse to reject the inheritance provided by the will and instead claim a percentage of the decedent's augmented estate. This right exists precisely to prevent a spouse from being effectively disinherited.

Under SDCL 29A-2-202, the elective share percentage is based on the length of the marriage — it scales upward the longer the marriage lasted, with longer marriages yielding a larger share. The "augmented estate" includes not just the probate estate but also certain non-probate transfers that occurred during the marriage, preventing a spouse from circumventing the elective share by simply moving assets outside of probate.

To claim the elective share, the surviving spouse must file a petition with the circuit court within nine months of the decedent's death, or within four months after the will is formally admitted to probate — whichever is later. A court may extend the time for good cause under SDCL 29A-2-211.

Whether to claim the elective share requires careful calculation. If what the will provides is already more than the elective share percentage would yield, there's no benefit to filing. If the will provides less, or nothing at all, the elective share claim may significantly increase what the surviving spouse receives.

The Family Allowance

Separate from the elective share, South Dakota provides a family allowance to support the surviving spouse and minor children during the period of estate administration. Under SDCL 29A-2-403, this allowance can be up to $18,000 and is payable as a lump sum or in periodic payments.

The family allowance is not limited to cases of financial need — any surviving spouse may claim it. More importantly, it takes priority over most creditor claims, including:

• General unsecured debts (credit cards, medical bills)
• South Dakota Medicaid estate recovery claims by DSS

The family allowance has priority over all claims except the homestead and exempt-property allowances.

The family allowance is in addition to the surviving spouse's inheritance under the will or intestate succession — it's not an advance or a deduction from what they would otherwise receive.

Homestead Allowance

South Dakota's homestead allowance provides the surviving spouse or minor children with homestead rights during administration. Under SDCL 29A-2-402, the allowance is provided as set out in Chapter 43-31, and the surviving spouse also has exempt-property rights under Chapter 43-45.

The homestead allowance and exempt property are in addition to the surviving spouse's will, intestate, or elective-share interests and have priority over all claims.

Exempt Property

Beyond the homestead and family allowances, SDCL 29A-2-402 provides the surviving spouse with the exempt property described in Chapter 43-45. The qualifying property and amount depend on those exemption provisions.

These rights are in addition to the surviving spouse's inheritance under the will, intestate succession, or elective share.

Surviving Spouse Rights in an Intestate Estate

If the deceased left no valid will, South Dakota's intestate succession rules determine who inherits. Under SDCL 29A-2-102, the surviving spouse's share depends on whether the decedent had children from outside the marriage:

• If all of the decedent's children are also the surviving spouse's children: The surviving spouse inherits the entire estate.
• If one or more of the decedent's surviving descendants are not descendants of the surviving spouse: The surviving spouse inherits the first $100,000 of the estate plus one-half of any remainder. The decedent's other descendants share the rest.
• If the decedent has no surviving descendants: The surviving spouse inherits the entire estate.

These rules apply to probate assets — property held outside of probate (joint tenancy, beneficiary designations, trusts) passes by other mechanisms regardless of the intestate succession rules.

Medicaid Recovery and Surviving Spouses

If the deceased received Medicaid benefits for nursing facility care, home and community-based services, or hospital care while age 55 or older, the South Dakota Department of Social Services (DSS) may have a recovery claim against the estate. This is one of the most significant financial risks surviving spouses face.

However, South Dakota law suspends Medicaid recovery while a surviving spouse is still alive. Recovery is deferred until after the surviving spouse's death.

Additionally, the surviving spouse has a six-month window from the date of the Medicaid recipient's death to file a Petition to Limit Financial Responsibility, which can further protect assets.

What to Do First

If your spouse recently died and you are uncertain about your rights:

1. Do not delay. The elective-share petition deadline is nine months after death or four months after will admission, whichever is later, subject to a possible court extension for good cause.
2. Identify the size and composition of the estate — probate assets, non-probate assets, and any debts including potential Medicaid recovery.
3. Compare what the will provides against what the elective share would yield.
4. Claim the family allowance early — it's available immediately and takes priority over creditors.
5. Consult a South Dakota probate attorney if the estate is large, if a Medicaid claim is expected, or if the will appears to significantly undercut your statutory rights.

South Dakota's surviving spouse protections are meaningful but require action within specific deadlines. Knowing your rights is the first step — exercising them within the statutory windows is what actually protects your share of the estate.
