Time matters for owners in South Dakota. A severed interest left unused for 23 years can be terminated and returned to the surface owner under S.D.C.L. 43-30A.
Quick answer: In South Dakota, a severed mineral interest is not permanent: it can revert to the surface owner if it goes unused. South Dakota's dormant minerals act runs on a 23 year nonuse period before a severed interest can lapse to the surface owner. The governing statute is S.D.C.L. 43-30A. To keep it alive, record a statement of claim, or use the interest within 23 years (S.D.C.L. 43-30A-3). If you may sell, confirm the clock has been met first.
South Dakota can terminate a severed mineral interest after 23 years of nonuse under S.D.C.L. 43-30A. As of June 2026.
South Dakota's dormant minerals act runs on a 23 year nonuse period before a severed interest can lapse to the surface owner. If the interest goes 23 years without use, a lease, production, or a recorded notice, the surface owner can act, so the practical task is knowing when it was last touched.
South Dakota scores 79 out of 100 on the Dormancy Risk Score and ranks number 13 of 51 for how easily an absent owner can lose a severed interest.
South Dakota counts a wide range of acts as use, each resetting the 23 year clock. Under S.D.C.L. 43-30A-3 the interest is used by production with the owner permission, by injection, withdrawal, or storage operations, by production from a common vein for solid minerals, by a recorded conveyance, lease, mortgage, assignment, probate distribution, transfer on death deed, or judgment that specifically refers to the interest, by an agreement to pool or unitize, or by recording a statement of claim under 43-30A-4.
Enter the date the interest was last used, such as a sale, lease, recorded filing, drilling permit, or production, to see when it could lapse and exactly what resets the clock.
South Dakota uses forced pooling to assemble drilling units, so a single owner cannot block development and instead takes a statutory share.
South Dakota protects surface owners by statute, requiring notice and compensation when an operator disturbs land to reach severed minerals.
It can. In South Dakota, 23 years without qualifying activity puts a severed interest at risk of reverting.
It takes 23 years of nonuse, and even then only after the statutory notice and preservation window.
Yes. A non consenting owner can be pooled into a unit in South Dakota.
Record a statement of claim, or within 23 years take production, record a transaction that refers to the interest, or join a pooling or unitization agreement (S.D.C.L. 43-30A-3).
