In South Dakota, a named life insurance beneficiary receives the death benefit directly, outside your will and outside probate; divorce automatically revokes an ex-spouse’s designation under SDCL 29A-2-804; and if no named beneficiary survives you, the proceeds typically fall to your estate.
The qualifier — and it’s a big one: the divorce-revocation rule applies to policies governed by state law. Employer-sponsored group life insurance governed by ERISA is preempted by federal law (the U.S. Supreme Court’s Egelhoff v. Egelhoff decision), so an unchanged designation on a workplace policy can still pay an ex-spouse even after a South Dakota divorce. The statute also yields to the policy’s express terms, a court order, or the marital settlement agreement.
The rules at a glance
| Situation | What South Dakota law provides |
|---|---|
| Named beneficiary survives you | Benefit pays directly to them, outside probate |
| Divorce | Ex-spouse’s designation revoked automatically — SDCL 29A-2-804 — unless policy terms, a court order, or the settlement says otherwise |
| ERISA group policy (workplace) | Federal law preempts the state revocation rule; the designation on file controls |
| No surviving named beneficiary | Proceeds typically payable to your estate — probate delay, possible creditor exposure |
| Minor named as beneficiary | Insurers generally can’t pay a minor directly; guardianship, UTMA custodian, or a trust fills the gap |
| Buyer’s remorse | Every individual policy delivered in SD carries a 10-day free look — return it in writing for a full refund (SDCL 58-15-8.1) |
Three practical takeaways:
- The designation form outranks your will. Updating a will does not change who a life insurance policy pays. The beneficiary form on file with the insurer controls.
- Divorce is the moment designations break. State law protects you on individually owned policies; your 401(k) life coverage and other ERISA plans need a manual update, because federal law leaves the old form in force.
- Always name a contingent. The estate default is the worst-case routing — slower, and potentially exposed to creditors — and one extra line on the form avoids it.
One more distinction worth knowing: these rules govern insurance contracts and state probate. Assets the federal government holds in trust — trust land and Individual Indian Money accounts — follow a different process entirely, the federal probate under the American Indian Probate Reform Act; see does life insurance go through probate on trust land?
