South Dakota Property Study Guide

Half of what you need to know about South Dakota property law is a list of things the state does not have. No prescribed standard fire policy. No FAIR plan. No statutory appraisal clause. No statutory proof-of-loss deadline. No credit-scoring statute. A national outline fills each of those gaps with another state’s rule, and every one of those fills is a wrong answer here. The other half is a single statute — a valued policy law that covers three perils, sits in a chapter nobody would search, and is wrapped in provisos that decide most of the questions asked about it.

The valued policy law, and where it hides

SDCL 58-10-10 is South Dakota’s valued policy law, and it sits in chapter 58-10, “Insurable Interest” — not in a fire chapter, because South Dakota has none. Its catchline names its scope precisely: “Insurance against fire, tornado, or lightning — Measure of damages where property wholly destroyed.”

Three perils, not one. Fire, tornado, or lightning. On a question that supplies a hail loss or a windstorm loss, the section does not engage.

The operative rule reaches real property: “Whenever any insurance policy is written or renewed to insure any real property in this state, including structures on land owned by a person other than the insured, against loss by fire, tornado, or lightning and the property insured is wholly destroyed, without criminal fault on the part of the insured or the insured’s assigns, the amount of insurance written in the policy shall be taken conclusively to be the true value of the property insured and the true amount of the loss and measure of damages.”

Note the two qualifiers inside that sentence before the provisos even begin: the property must be wholly destroyed, and the destruction must be without criminal fault on the part of the insured or an assign.

The provisos are the exam

Read past the headline rule, because the section keeps going and the exam follows it.

Timing. The loss must occur ninety or more days after the policy issued, or ninety or more days after a twenty-five percent or greater increase in limits. That is the anti-selection guard, and it is the proviso most often dropped.

Exceptions to the timing rule. Unchanged renewals, inflation-adjustment policies, and replacement-cost conversions made by written agreement are treated differently.

Special settlements. Builders’ risk is settled “according to the actual value of that portion of the construction completed at the time of the fire, tornado, or lightning loss.” Newly constructed residential property is settled per the policy’s own valuation terms for the completed portion. Appurtenant structures are settled at actual replacement or actual cash value depending on what the policy provides — “unless a specific value was assigned to each structure or property prior to the loss,” in which case the assigned value governs.

Blanket forms are outside the section altogether. “This section does not apply to any claim for total loss to any building which is insured under a commercial blanket form with one amount covering two or more buildings.” A schedule of buildings written under one blanket limit is settled on the policy’s own terms, not on the valued-policy rule.

Multiple policies. Where two or more policies are written on the same property interest, “each insurer shall pay only that proportion of the cost of the loss that the limit of liability under its policy bears to the total amount of insurance covering the loss.”

And one absence that decides a whole category of question: partial losses are not addressed. The section is triggered only where the property is wholly destroyed. On a partial loss you are back to the policy’s own valuation terms — and South Dakota prescribes no form to override them.

There is no standard fire policy, and three other rules follow from that

South Dakota does not prescribe a standard fire policy in the 165-lines sense. There is no fire policy chapter in Title 58 at all — chapter 58-24 is rates, not forms.

What South Dakota uses instead is generic. SDCL 58-11-5 provides that “Insurance contracts shall contain such standard or uniform provisions as are required by the applicable provisions of this title pertaining to contracts of particular kinds of insurance,” with a director power to waive a particular provision. Control of the actual wording then runs through filing and approval — 58-11-12, the form filing standards and review clocks at 58-11-63 to 58-11-77, and ARSD chapter 20:06:28.

Three consequences follow, and each is a question in its own right.

No statutory appraisal clause. Because no form is prescribed, an appraisal provision is a matter of the filed form rather than of the code.

No statutory property proof-of-loss deadline. The only general provision is SDCL 58-12-1, which requires the insurer to “furnish, upon written request of any person claiming to have a loss under an insurance contract issued by such insurer, forms of proof of loss for completion by such person” — and expressly disclaims responsibility for “the completion of such proof or the manner of any such completion or attempted completion.” It sets no deadline in either direction. The ninety-day figure a candidate half-remembers is 58-17-24, and it is health only.

Rate regulation is file-and-use, on the statute’s own words. SDCL 58-24-10: “The filing date is the effective date thereof unless the insurer proposes an effective date subsequent to the filing date.” Two carve-outs sit in the same section — inland marine risks not customarily written to manual rates, and motor vehicle insurance, which runs under 58-24-10.1 — and 58-24-10.2 lets the director pull a line into prior approval “on finding that closer supervision is required.”

No FAIR plan, and what South Dakota has instead

There is no FAIR plan, joint underwriting association or property residual market chapter anywhere in Title 58’s seventy-nine chapters. South Dakota is landlocked, so there is no coastal wind pool or beach plan either.

The state does run residual mechanisms — just not for property. SDCL 58-11-57 directs the director, “After consultation with insurance companies authorized to issue automobile liability policies in this state,” to approve “reasonable plans for the equitable apportionment of motor vehicle liability policies of applicants who are in good faith entitled to but are unable to procure policies through ordinary methods.” That is an automobile assigned risk plan, and the statute does not name it. Health has a risk pool at ARSD chapter 20:06:48. Property has neither.

Where hard-to-place property goes instead is the non-admitted market — which in South Dakota means chapter 58-32, a surplus line broker, and a “diligent effort” standard that states no minimum number of declinations.

Credit-based insurance scores: an absence, not a permission

No South Dakota statute or rule on credit-based insurance scores appears in the Title 58 chapter index, in chapter 58-11’s seventy-seven sections, or in the sixty chapters of ARSD article 20:06.

That is worth stating carefully, because the two possible readings are very different. It does not mean South Dakota has legislated permission to use credit; it means the state has legislated nothing. A producer who tells a South Dakota consumer that a credit-scoring statute protects them is describing a law that does not exist.
