South Dakota County
Bennett County, South Dakota
Martin and Pine Ridge border country - from Martin's role as the governmental and commercial hub of Bennett County to the county's position along the Pine Ridge Indian Reservation border (Bennett County borders the Oglala Lakota Nation's Pine Ridge Reservation to the south, and the county's ranching economy, Native American cultural connections, and remote Great Plains character define a corner of southwest South Dakota that retains a distinctly frontier character among the rolling mixed-grass prairie and ponderosa pine draws of the southern Black Hills region).

Key Assets: Bennett County is genuinely home to LACREEK NATIONAL WILDLIFE REFUGE, a 16,570-acre wetland sanctuary established in 1935 and the only national wildlife refuge in South Dakota headquartered west of the Missouri River; nestled within the shallow Lake Creek valley on the northern edge of the Nebraska Sandhills, the refuge combines native sandhills, sub-irrigated meadows, freshwater marshes, and tall and mixed-grass prairie, serving as a critical staging area for migrating waterfowl, sandhill cranes, shorebirds, and grassland-dependent birds along the Central Flyway – one of only four major migratory bird corridors in North America; more than 282 different bird species have been documented at the refuge since 1959, and it is genuinely one of the few places in South Dakota where visitors might hear both an eastern and a western meadowlark singing from the very same spot; most remarkably, Lacreek played a foundational role in one of American conservation’s great comeback stories: after market hunting for their quills, feathers, and skins, combined with widespread habitat loss, had completely wiped out trumpeter swans from central and eastern North America by the early 1900s, the U.S. Fish and Wildlife Service selected Lacreek in the early 1960s to launch the first trumpeter swan restoration effort anywhere in the Midwest – between 1960 and 1962, 57 cygnets were carefully transported from Red Rock Lakes National Wildlife Refuge in Montana, at the time the largest trumpeter swan reintroduction effort ever attempted; the effort succeeded remarkably: by 1964, the first successful trumpeter swan nest in almost a century was documented near Valentine, Nebraska, and the descendants of those original Lacreek swans are found today throughout the Central Flyway as the “High Plains Flock,” with winter counts at the refuge itself reaching as high as 500 birds in January 2022; the refuge also hosts a dedicated Prairie Grouse Viewing Blind, allowing visitors each spring to observe the elaborate mating dances (“leks”) of native prairie grouse
Notes: Lacreek National Wildlife Refuge’s genuine, extensively documented role as the birthplace of the Midwest’s trumpeter swan restoration – reviving a species wiped out from the region by the early 1900s – is one of the most significant wildlife conservation achievements found anywhere in this project.

IMPORTANT CONTEXT
Bennett County occupies a unique legal history: it was formally removed from the Pine Ridge Indian Reservation by an act of Congress in 1909-1912, though much of the county’s land remains held in trust by the reservation. Residents navigating land, jurisdiction, or tribal-related matters should confirm current details directly with the relevant county and tribal offices, as jurisdictional arrangements can be complex.
NOTES
Bennett County is genuinely home to Lacreek National Wildlife Refuge, birthplace of the Midwest’s trumpeter swan restoration effort in the 1960s. All contact information above was sourced from official county, city, library, and refuge pages as of this writing; phone numbers and hours should be reconfirmed directly with the relevant office before a visit.
About Bennett County
Bennett County is southwest South Dakota’s Pine Ridge border and ranching county – cattle ranching on the mixed-grass prairie defines the land use while the county’s proximity to the Oglala Lakota Nation and the remote Black Hills region gives it a distinct Great Plains character anchored by Martin’s small-city services.
Martin (the county seat, population ~1,000) is Bennett County’s governmental and commercial hub, serving ranching families across one of South Dakota’s more remote southwestern counties.

Probate & Estate
Losing someone and having to deal with courts and paperwork at the same time is hard. This section won’t make that easier, but it should tell you what to expect, what it costs, and where to go – so at least you’re not walking in blind.
Where to go
Clerk of Courts, Bennett County PO Box 460, Martin, SD 57551 (605) 685-6969 Bennett County is in southwestern South Dakota, seated in Martin.
Step 1: figure out which path applies
South Dakota HAS adopted the Uniform Probate Code (Articles I, II, III, IV, and VIII, effective July 1, 1995). Probate proceedings are handled by the Circuit Court in the county where the decedent lived, generally administered under the supervision of the Clerk of Courts.
Small Estate Affidavit – Collection of Personal Property (SDCL § 29A-3-1201) – available when the total gross value of the entire estate, wherever located, less liens and encumbrances, does not exceed $50,000. At least 30 days must have passed since death, no petition for appointment of a personal representative is pending or has been granted anywhere, and the decedent had no outstanding debts to the Department of Social Services for medical assistance or institutional/nursing home care. A separate affidavit exists for South Dakota real estate under $50,000, which must also be filed with the Register of Deeds where the property sits.
Informal Probate – the most common track in South Dakota, used when heirs and beneficiaries are getting along and no disputes are expected.
Unsupervised Formal Probate and Supervised Formal Probate – for more complex or contested situations.
Step 2: filing for administration
The personal representative (or an interested party) files an application or petition with the Clerk of Courts in Bennett County, along with the original will if one exists.
For informal probate, the clerk reviews the application administratively and issues Letters Testamentary or Letters of Administration without a hearing in most cases.
Formal proceedings require notice to interested parties and, if contested, a hearing before the circuit judge.
The personal representative gathers and inventories assets, notifies creditors, and pays valid debts and expenses.
After debts and taxes are satisfied, remaining assets are distributed according to the will or South Dakota’s intestacy statutes (SDCL Chapter 29A-2).
The estate is formally closed by filing a sworn closing statement or a petition for formal order of discharge (SDCL § 29A-3-1003).
What it costs
Court costs are set by law and paid to the Clerk of Courts; confirm current fees with Bennett County directly.
South Dakota has NO state estate tax and NO state inheritance tax. Only the federal estate tax may apply, and only to very large estates.
A surviving spouse cannot be disinherited in South Dakota unless the spouse agrees.
