South Dakota mineral rights

SDCL 45-5A-3, Definition of terms

The baseline rule is one sentence carried over from the 1877 Civil Code: the owner of land in fee has the right to the surface and to everything permanently situated beneath or above it. Everything else is a departure from that by grant or reservation. When the estates are split, the surface damages act supplies the working definitions, and its definition of a mineral is unusually wide. A mineral is any substance with economic value, whether organic or inorganic, that can be extracted from the earth, including oil and gas, but excluding water. A mineral estate is an estate in or ownership of all or part of the minerals underlying a specified tract; a surface estate is the same for the surface; and a surface owner is the person who has possession of the surface if other than the mineral developer, either as owner or as lessee. That last clause is what lets a tenant claim under the chapter. The abandonment chapter defines the mineral interest it can extinguish separately and by naming substances first, reaching oil, gas, coal, clay, gravel and uranium and then all other minerals of any kind and nature.

Checked August 4, 2026. Read at SDCL 43-16-1 and 45-5A-3 on 2026-08-04, with 43-30A-1 for the second definition. Chapter 43-16 is titled Land Boundaries, Monuments and Subsurface Rights and its subsurface content is that single sentence: the words mineral, oil, gas and coal return zero occurrences across the whole chapter, which is otherwise about lateral support, roads, boundary trees and monuments.

SDCL 43-30A-2, Abandonment by nonuse--Title vests in surface owner

A South Dakota mineral interest is abandoned if it has not been used for twenty-three years or more, and title to it vests in the owner of the surface estate on the date of abandonment. No judge is required for that to happen. Seven things count as use: production by or with the express permission of the record owner; operations for injection, withdrawal, storage or disposal of water, gas or other fluid substances to produce or enhance production; production from a common vein or seam for solid minerals; the recording within the last twenty-three years of any valid conveyance, lease, mortgage, assignment, probate distribution, termination of joint tenancy affidavit, termination of life estate affidavit, transfer on death deed, judgment or decree making specific reference to the record owner's mineral interest; being subject to an agreement to pool or unitize; recording a statement of claim; or a proper instrument recorded before an affidavit recorded under the older marketable title chapter. The mineral interest defined for this purpose is a broad one, naming oil, gas, coal, clay, gravel and uranium and then reaching all other minerals of any kind and nature. Interests owned by a governmental body are exempt, the chapter applies both prospectively and retrospectively, and its provisions may not be waived until the twenty-three years have run.

Checked August 4, 2026. Chapter 43-30A read end to end on 2026-08-04, all twelve section numbers including the repealed ones. The twenty-three year figure is the current one: the section was enacted by SL 1985, ch 338, § 2 and amended by SL 2016, ch 215, § 1.

SDCL 43-30A-6, Notice by surface owner--Contents--Proof of publication and mailing

To succeed to an abandoned interest the surface owner must publish notice of the lapse once each week for three weeks in the official newspaper of the county, and must also mail a copy by registered or certified mail to the record owner at the record owner's address of record no later than ten days after the last publication. The surface owner may rely on the last address of record at the county register of deeds. Then the section allocates the burden, and it does so against the mineral owner in terms: it is the record mineral owner's obligation to maintain an address of record in that office, and failure to maintain one is a waiver by the record mineral owner of the requirement to mail the notice at all. Recording a copy of the notice with an affidavit of publication and of any mailing is prima facie evidence that notice was properly given. There is no duty of search or inquiry on the surface owner anywhere in the chapter.

Checked August 4, 2026. Read in full at SDCL 43-30A-6 on 2026-08-04. The waiver sentence was added by SL 2016, ch 215, § 5, the same session law that lengthened the period to twenty-three years. Neighbouring North Dakota arranges this the other way: its act defines a reasonable inquiry and lists four searches the surface owner must make. No comparable duty appears anywhere in chapter 43-30A, which was read end to end.

SDCL 43-30A-5, Circumstances in which failure to record statement does not cause abandonment

The statement of claim is normally due before the twenty-three years expire. It must be recorded for the record owner of the mineral interest, contain the owner's name and mailing address and a legal description of the land, and be recorded with the register of deeds in the county where the interest is located; a joint tenant may record for the other joint tenants, but a tenant in common may not. Missing that deadline is not fatal. Failure to record in time does not cause abandonment if the record owner records a statement of claim within sixty days after completion of the publication of the notice of lapse. The interest is treated as in use on the date of recording.

Checked August 4, 2026. Read at SDCL 43-30A-5 and 43-30A-4 on 2026-08-04. Note the trigger differs from North Dakota's sixty days, which runs from the FIRST publication; South Dakota's runs from the completion of publication, which is three weeks later.

SDCL 43-30B-6, Actions not use of mineral interest under chapter 43-30A

Any person or entity holding an interest in a tract may petition the circuit court in that county to declare a trust in favour of the owner of a mineral interest in it whose location or identity cannot be determined. On a showing that the trust is in the owner's best interest and that the petitioner cannot locate or identify them after due diligence, the court declares the trust, appoints the county treasurer or another person as trustee, and authorises the trustee to execute a mineral lease, a ratification, a division order or any other related instrument on terms the court approves. The county treasurer may decline, in which case the court appoints an alternate. All bonuses, rentals, royalties and other income are paid to the trustee, who administers the trust under title 55; if the income does not cover the fees and costs, the petitioner indemnifies the fund. The trust runs until the court finds that an owner has appeared and been identified, with no outside time limit. And then the chapter closes the door it might have opened: no act taken by or on the permission of a trustee, petitioner or court under it counts as use of the mineral interest under the abandonment chapter. So a missing owner's minerals can be leased and can be producing, with the money accruing to them in a county-held trust, while the twenty-three years keep running against the interest itself.

Checked August 4, 2026. Chapter 43-30B read end to end on 2026-08-04, all seven sections. The chapter is recent: SL 2013, ch 223, substantially rewritten by SL 2017, ch 189. Illinois has the other court-declared trust on this record and it works the opposite way round, ending in the court conveying the interest to the surface owner seven years on; South Dakota's trust never ends of itself and the divesting is done by the separate abandonment chapter instead.

SDCL 43-30-3, Marketable record title held free and clear of interest, claims, and charges--Limitation--Notice of claim of interest

Separately from the abandonment chapter, South Dakota has had a marketable record title act since 1947. A person with an unbroken chain of title to any interest in land for twenty-two years or longer, who is in possession of the land, has marketable record title to that interest. That title is held free and clear of all interests, claims and charges whatever which depend on any act, transaction, event or omission twenty-two years or more earlier, whether or not evidenced by a recorded instrument, unless the claimant files a verified notice of claim within twenty-three years of the recording of the deed under which title is claimed. No disability and no lack of knowledge of any kind on anyone's part extends that time. The claims barred are defined as any and all interests of any nature whatever, however denominated. Possession may be shown of record by an affidavit of possession, which cannot be filed until twenty-three years after the conveyance it rests on. The chapter's exceptions cover lessors and reversioners, remaindermen, the state and the United States, and railroad and public utility land. None of them mentions minerals, and the words mineral, oil, gas and coal do not occur anywhere in the chapter. WHAT THAT ADDS UP TO FOR A SEVERED MINERAL INTEREST IS NOT SETTLED HERE, and the page does not pretend otherwise. The act reaches every interest it does not except, which is the shape that makes Florida's act reach minerals by saying nothing about them. But it operates in favour of a person in possession, and a severed mineral owner is not in possession; and the Legislature enacted a dedicated abandonment chapter thirty-eight years later, which is not what a legislature does if the older act already did the work. Pointing the other way, the abandonment chapter treats a mineral owner as having needed to guard against an affidavit of possession recorded under this chapter's section 43-30-7 under prior law. This record reports both readings and resolves neither.

Checked August 4, 2026. Chapter 43-30 read end to end on 2026-08-04, 16,594 characters, and every sentence stated above was read in the chapter itself. The controls: the words mineral, oil, gas and coal each return zero occurrences, against possession at eleven. What is verified here is what the act SAYS and does not say. What is deliberately left open is what it does to a severed mineral estate, because no section read answers that and the two pointers in the text run against each other: the bar reaches any and all interests of any nature whatever, while the operative section requires possession. Nobody should read this rule as establishing that a South Dakota mineral interest does, or does not, survive chapter 43-30 on its own. That question is listed in what this page does not answer yet.

SDCL 45-5A-2, Purpose of chapter

South Dakota's surface damages act opens by telling whoever applies it which way to lean. Its stated purpose is to provide the maximum amount of constitutionally permissible protection to surface owners from the undesirable effects of mineral development, and it directs that the chapter is to be interpreted to benefit surface owners regardless of when the mineral estate was separated from the surface estate. The findings behind it are agricultural: that the state's public welfare is largely dependent on agriculture, that mineral and oil and gas development may interfere with the use of the surface, and that surface owners should be justly compensated. On the substance, the mineral developer must pay the surface owner a sum equal to the damages sustained for loss of agricultural production, lost land value and lost value of improvements caused by mineral development. The amount may be fixed by any formula the two agree on, consideration is given to the period over which the loss occurs, and the surface owner may elect to be paid in annual instalments, except that harm from exploration is compensated by a single sum only. Payments cover only land directly affected, and payment for lost land value goes only to the title holder.

Checked August 4, 2026. Chapter 45-5A read end to end on 2026-08-04, all fifteen section numbers. The chapter dates to SL 1982, ch 304, and the definitions in 45-5A-3 tie mineral development to operations commenced subsequent to June 30, 1982.

SDCL 45-5A-4.1, Treble damages for failure to negotiate in good faith

Two separate penalties sit on top of the compensation. If a mineral developer fails or refuses to conduct good faith negotiations with the surface owner to determine damages, whether or not arising out of an existing contract or lease, the court in any subsequent litigation may at its discretion award treble damages on all or part of the surface owner's recovery. Separately, if the developer fails to give the notice the chapter requires before entering for exploration, the surface owner and the surface lessee may seek actual and punitive damages in court. The developer is also responsible for all damage to real or personal property resulting from a lack of ordinary care, and for all damage resulting from an interference caused by mineral development, which is a broader head than negligence alone. The surface owner has two years from when the injury becomes apparent, or should have become apparent to a reasonable person, to notify the developer in writing; the developer then has sixty days to make a written offer of settlement, and the surface owner sixty days to accept or reject it before suing. Nothing in the chapter precludes any other remedy allowed by law.

Checked August 4, 2026. Read at SDCL 45-5A-4.1, 45-5A-5.2, 45-5A-6, 45-5A-7, 45-5A-8, 45-5A-9 and 45-5A-10 on 2026-08-04. The treble damages section is recent, SL 2013, ch 225, and the punitive damages section is SL 2013, ch 226, amended SL 2014, ch 213. This is the opposite arrangement from Alabama, where the statutory remedies are declared the sole and exclusive remedies and punitive damages are excluded.

SDCL 45-5A-5, Notice to surface owner of proposed surface disturbing development activities

The chapter runs two notice periods keyed to how invasive the work is. For surface disturbing development activities, meaning well site construction, road building, grading, excavation, demolition and related work, the developer must give the surface owner written notice at least thirty days before operations commence, sent to the record surface owner at the address shown by the county register of deeds. That notice must disclose the plan of work and operations in enough detail for the surface owner to evaluate the effect on their use of the property, and it must include a form prepared by the Department of Agriculture and Natural Resources advising the surface owner of their rights and options under the chapter. For activities that do not disturb the surface, such as surveying and well staking, seven days notice by registered mail or hand delivery is required, and it goes to the surface lessee as well as the owner, and must carry the developer's name, address and telephone number, an offer to discuss the exploration plan before operations begin, and a diagram of the approximate location of the proposed drilling site. Both notice regimes fall away if the developer and the surface owner or lessee already have a use agreement or contract covering the property.

Checked August 4, 2026. Read at SDCL 45-5A-5, 45-5A-5.1 and 45-5A-5.3 on 2026-08-04. The seven day exploration notice and the existing-agreement exception both date to SL 2013, ch 226. Note the two sections use different address sources: the thirty day notice goes to the address at the register of deeds, the seven day notice to the address shown by the county treasurer.

SDCL 45-9-35, Rights of owners operating well or paying costs for benefit of another under pooling order

In the absence of voluntary pooling the Board of Minerals and Environment or the secretary must, on the application of any interested person, enter an order pooling all interests in the spacing unit, after notice and opportunity for hearing, on terms that are just and reasonable and that afford the owner of each tract or interest the opportunity to receive their just and equitable share without unnecessary expense. The order prescribes how owners elect to participate and provides for payment of the reasonable actual cost of drilling, equipping and operating by those who do, plus a reasonable charge for supervision and interest. An owner who does not want the risk has alternatives that the order must provide if requested: surrender the leasehold interest to the participating owners on some reasonable basis for reasonable consideration, or participate on a limited or carried basis on terms the board finds just and reasonable. If another owner carries the cost, that owner takes the non-participant's share of production until the market value of it equals the sums charged to that interest, but expressly exclusive of a royalty not to exceed one-eighth of production. So the carried owner keeps an eighth flowing throughout, and no multiple of costs, penalty or risk charge appears anywhere in the sections read.

Checked August 4, 2026. Read at SDCL 45-9-31, 45-9-32, 45-9-33, 45-9-35 and 45-9-36 on 2026-08-04, all from SL 1953, ch 220. The absence of a risk penalty is a reading of those sections, which set out cost recovery and stop there. Compare Florida, where a silent owner is carried at three hundred percent of costs, and Arizona, where the statute gives a just and equitable share with no cost-free fraction written in at all.

SDCL 43-28-17, Priority of first recorded conveyance of real property--Conveyance defined

Every conveyance of real property other than a lease for a term not exceeding one year is void as against a subsequent purchaser or encumbrancer, including the assignee of a mortgage, lease or other conditional estate, who takes in good faith and for a valuable consideration and whose conveyance is first duly recorded. All three conditions must hold together, which makes South Dakota a race-notice state rather than a pure race one. Conveyance is defined broadly for this purpose, embracing every written instrument by which any estate or interest in real property is created or aliened. An unrecorded instrument remains valid between the parties to it and against anyone who has notice of it, so recording protects against strangers rather than perfecting the deed itself, and the recording and deposit of a properly proved and certified instrument is constructive notice to purchasers and encumbrancers from the time it is recorded.

Checked August 4, 2026. Read at SDCL 43-28-17, 43-28-14 and 43-28-15 on 2026-08-04. Chapter 43-28 was read whole, 28,025 characters, and the words mineral, oil, gas and coal return zero occurrences in it, so there is no mineral-specific recording provision and a mineral instrument records like any other. This is the opposite arrangement from Delaware and North Carolina, both pure race, where being first to the office settles it whatever the second taker knew.

SDCL 45-6C-55, Confidentiality period of certain mineral exploration reports

South Dakota starts from disclosure and carves out exceptions, rather than starting from secrecy. Information provided to state agencies in a notice of intent to conduct exploration is public information, with the tentative test hole locations the protected exception and disclosure of protected material a misdemeanour. Well data is on a timer: the board may require mechanical well logs, directional surveys and reports on well location, drilling and production to be filed within thirty days after a well is completed or abandoned, and samples, core chips and complete cores within six months, but the log, samples and cores of an exploratory or wildcat well may be held confidential, on the operator's written request, only until six months after the well is completed. Older exploration filings were put on the same footing retrospectively: geologic reports, aquifer penetration reports, maps and test hole logs from operations initiated or permitted before July 1982 were made confidential for six months following July 1, 2008, extendable by written request for no more than five further years, after which the statute says the information becomes public.

Checked August 4, 2026. Read at SDCL 45-6C-14, 45-6C-55, 45-6D-67 and 45-9-18 on 2026-08-04. The two confidentiality-period sections are word for word identical, enacted once each into the mineral exploration and uranium exploration chapters by SL 2008, ch 229. This is the far end of a spread this record has now seen three points on: Delaware makes exploration data confidential and criminalises the official who discloses it, Massachusetts makes a coal explorer publish its results after a hundred and eighty days, and South Dakota makes the filing public to begin with.

SDCL 43-41B-1, Definitions and use of terms

South Dakota's Uniform Unclaimed Property Act names unpaid mineral proceeds once, in the definition of intangible property, listing them alongside moneys, checks, drafts, deposits, interest, dividends, royalties, vendor checks, income, unpaid commissions, unpaid overcharges and unpaid accounts payable. Having named them it gives them nothing further: there is no mineral-specific dormancy period, no aggregation rule for proceeds one holder is keeping for one owner, and no provision distinguishing suspended royalty from any other unpaid balance. So the general rule governs, and it is a short one. All intangible property held in the ordinary course of a holder's business that has remained unclaimed by the owner for more than three years after it became payable or distributable is presumed abandoned, and property counts as payable or distributable even though the owner never demanded it or presented the instrument required to collect it.

Checked August 4, 2026. Chapter 43-41B read whole on 2026-08-04, 73,495 characters, with mineral returning a single occurrence, the one quoted here, against a control of the general presumption section. Idaho and Maine do the same thing, naming mineral proceeds in a definition and attaching no period to them.
