South Dakota living trusts & estate documents

Living trust law in South Dakota

A revocable living trust holds your home, accounts, and other property during your life, you stay in full control as trustee and can change or revoke it any time, then passes it to your beneficiaries without probate when you're gone. In South Dakota, trusts are governed by the SDCL Title 55 (Fiduciaries and Trusts), as amended by 2026 SB 100, effective July 1, 2026.

Avoiding probate in South Dakota

Probate in South Dakota is governed by the SDCL Title 29A (UPC) and handled by the Circuit Court. See state probate code for administration options.

Collection by affidavit is available for personal property of $100,000 or less, with a separate affidavit for South Dakota real property of $50,000 or less (SDCL §§ 29A-3-1201, 29A-3-1203). Assets held in a funded living trust pass to your beneficiaries without probate, whatever the size of the estate. Many South Dakota homeowners set one up for that reason. South Dakota also authorizes a transfer-on-death deed (S.D. Codified Laws § 29A-6-401 et seq.) to pass real estate outside probate. A living trust does the same for every asset, not just real estate.

In South Dakota, creditors generally have 4 months after the first published notice (3-year outside bar from death) to file claims against the estate (SDCL § 29A-3-803), one reason court probate takes time that a funded trust avoids.

Estate and inheritance tax in South Dakota

South Dakota has no estate, inheritance, or income tax. The separate federal estate tax reaches only estates above $15 million per person (2026, adjusted yearly), so most families never owe it.

Protecting a surviving spouse in South Dakota

A surviving spouse in South Dakota who is left out of the will can instead claim an elective share scaled to the length of the marriage, up to 50% of the augmented estate under S.D. Codified Laws § 29A-2-202, a protection the will itself cannot override.

South Dakota also sets aside an area-limited homestead (one acre within a town plat, 160 acres otherwise, under SDCL 43-31-4) plus a family allowance up to $18,000 for the surviving spouse or minor children (S.D. Codified Laws § 29A-2-402), with priority over all claims against the estate.
