South Dakota Intestate Succession

When someone dies without a will in South Dakota, the state decides who gets what. There is no negotiation, no consideration of relationships or promises made — just a statutory formula under SDCL Title 29A that distributes assets based on family structure. If you are trying to figure out where you stand as an heir, understanding these rules is the first step toward knowing what to expect.

The Surviving Spouse's Share

South Dakota's intestate succession rules prioritize the surviving spouse, but the exact share depends on whether the deceased had children and whose children they are.

If all of the deceased's children are also children of the surviving spouse — meaning there are no children from prior relationships on either side — the surviving spouse inherits the entire estate. This is the simplest scenario and the most common one.

If the deceased had children from a prior relationship, the surviving spouse receives the first $100,000 of the estate plus one-half of the remaining balance. The deceased's children from the prior relationship split the other half.

If the surviving spouse has children from a prior relationship but the deceased does not, the surviving spouse still receives the first $100,000 plus one-half of the remainder.

If there are no surviving children or descendants, the surviving spouse inherits everything, regardless of whether the deceased's parents or siblings are alive.

Children's Share

When the deceased has no surviving spouse, children inherit equally. If a child predeceased the parent but left their own children (the deceased's grandchildren), those grandchildren step into their parent's share through a principle called "representation."

South Dakota treats adopted children the same as biological children for inheritance purposes. However, children who were given up for adoption and adopted by another family generally lose their inheritance rights from their biological parents.

When There Is No Spouse or Children

If the deceased left no surviving spouse and no descendants, the estate passes to the deceased's parents equally, or to the surviving parent if only one is alive.

If neither parent survives, the estate goes to siblings and their descendants. If no siblings survive, it continues to more distant relatives — grandparents, aunts, uncles, and cousins — following the degree of kinship.

If no relatives can be found at all, the estate "escheats" to the State of South Dakota.

Protections for the Surviving Spouse

Even before the intestate distribution is calculated, South Dakota law provides several protections that take priority over the general inheritance formula.

Homestead allowance: The surviving spouse is entitled to a homestead allowance that protects the family home from creditors and ensures a basic level of financial security during the estate settlement process.

Family allowance: Under South Dakota law, the surviving spouse (or dependent children) can claim up to $18,000 as a family allowance for maintenance during the probate process. This allowance has priority over most creditor claims — only administration costs and funeral expenses rank higher.

Exempt property: The surviving spouse can claim household furniture, furnishings, appliances, and personal effects up to $10,000 in value, exempt from creditor claims.

These protections apply whether the deceased died with or without a will. They are designed to prevent the surviving spouse from being left destitute while the estate works through probate.

What Counts as a Probate Asset

Intestate succession rules only apply to probate assets — property that was solely owned by the deceased with no designated beneficiary or survivorship mechanism. Common probate assets include:

• Bank accounts in the deceased's name alone (no POD designation)
• Real estate held solely in the deceased's name (no TOD deed or joint tenancy)
• Vehicles titled solely to the deceased
• Personal property, investments, and business interests

Assets that pass outside of probate — and therefore outside intestate succession — include joint tenancy property (passes to the surviving joint tenant), life insurance with named beneficiaries, retirement accounts with designated beneficiaries, payable-on-death bank accounts, and transfer-on-death deeds.

This distinction matters enormously. In many South Dakota estates, particularly those where the couple owned everything jointly, the probate estate may be small or even empty, meaning intestate succession has little practical effect.

The Probate Process Without a Will

Administering an intestate estate in South Dakota follows the same basic process as a testate estate, with a few key differences. Instead of a named executor, the court appoints an "administrator" based on the priority list in SDCL 29A-3-203 — typically the surviving spouse, then other heirs.

The administrator receives Letters of Administration rather than Letters Testamentary, but the duties are identical: inventory assets within three months, publish the creditor notice and wait four months, pay valid debts in priority order, and distribute the remainder according to the intestate formula.

The court filing fee is the same $122, and the process can be handled through informal probate if no one disputes the distribution.

The South Dakota Probate Process Guide covers both testate and intestate estates, walking administrators through every step from filing for appointment to closing the estate.

Common Complications

Blended families create the most friction in intestate succession. When the deceased has children from a prior marriage, the surviving spouse's share is reduced, and the split can feel deeply unfair to either side — especially when the family home is the estate's primary asset.

Unmarried partners receive nothing under South Dakota intestate succession, regardless of how long the relationship lasted. Only a legal spouse qualifies.

Estranged children inherit equally with children who maintained close relationships. The law does not consider the quality of family bonds.

These scenarios are precisely why estate planning attorneys encourage everyone to create a will. But when a will does not exist, the statutory formula is final.
