Are Beneficiary Designations Protected in South Dakota?
South Dakota automatically revokes an ex-spouse as beneficiary at divorceSDCL § 29A-2-804; § 29A-1-201Verified Sep 15, 2026View source; employer plans under ERISA follow federal rules either way, so a 401(k) beneficiary changes only by a new designation.
A beneficiary designation on life insurance, a retirement account, a payable-on-death bank account or a transfer-on-death brokerage account decides who receives that asset at death, in South Dakota as everywhere. The designation controls over the will or trust, and an outdated one stays in force whatever the other documents say.
Yes. South Dakota automatically revokes an ex-spouse as beneficiary on divorce for these asset types: life insurance, retirement accounts, pod accounts, tod accounts, annuitiesSDCL § 29A-2-804; § 29A-1-201Verified Sep 15, 2026View source. An ERISA-governed employer plan (a 401(k), a pension) follows federal law instead and must be updated by hand whatever the state rule says.
Yes. The federal Employee Retirement Income Security Act (ERISA) preempts state law for an employer-sponsored plan such as a 401(k), a pension or group life insurance: the plan pays the designation on file with the plan administrator, and a qualified plan requires the spouse's consent to name anyone else (Egelhoff v. Egelhoff, 2001; Kennedy v. Plan Administrator, 2009). South Dakota sets no spousal-consent requirement of its ownSDCL § 25-2-8; § 29A-2-202; § 29A-2-205Verified Sep 15, 2026View source for an individual account.
South Dakota gives inherited IRAs partial protection from creditorsSDCL § 43-45-16; § 43-45-17Verified Sep 15, 2026View source; the reach can depend on whether the IRA came from a spouse and whether the case is in state or federal court. After Clark v. Rameker (2014), federal bankruptcy law does not protect an inherited IRA on its own.
No. South Dakota does not default to per stirpes for beneficiary designationsSDCL § 29A-2-706 (Reserved); § 29A-2-709; § 29A-6-307; § 29A-6-310Verified Sep 15, 2026View source: when a named beneficiary dies before the account holder, the share lapses unless the designation says per stirpes or names a contingent beneficiary.
