South Dakota gives creditors six years to sue on a contract, obligation, or liability, express or implied. A South Dakota judgment or a sealed instrument gets twenty years, and a judgment from another state gets ten. A spoken promise does not extend the deadline; an acknowledgment counts only in a signed writing.
The deadlines, and where each one is written
| What is being collected | Deadline to file suit | Statute |
|---|---|---|
| A contract, obligation, or liability, express or implied | 6 years | SDCL 15-2-13(1) |
| A liability created by statute, other than a penalty or forfeiture | 6 years | SDCL 15-2-13(2) |
| A judgment or decree of a South Dakota court | 20 years | SDCL 15-2-6(1) |
| A sealed instrument, except a real estate mortgage | 20 years | SDCL 15-2-6(2) |
| A judgment of a federal court or of another state or territory | 10 years | SDCL 15-2-8(1) |
Section 15-2-13 lists the civil actions that “can be commenced only within six years after the cause of action shall have accrued,” starting with “[a]n action upon a contract, obligation, or liability, express or implied,” other than those covered by the longer periods in §§ 15-2-6 to 15-2-8 and two subdivisions of § 15-2-15.
Credit cards
Chapter 15-2 does not mention credit cards. Because the six-year rule covers contracts “express or implied” without separating written from oral agreements, an ordinary card or loan balance falls within it unless the creditor can show a sealed instrument.
What this means in practice: for an ordinary South Dakota card, loan, or account balance, the code points to six years from when the claim accrued.
When the clock starts, and what pauses it
Under § 15-2-4, on “a mutual, open, and current account where there have been reciprocal demands between the parties,” the claim accrues “from the time of the last item proved in the account on either side.” The chapter does not otherwise define accrual for a card or loan.
Under § 15-2-30, an action “is commenced as to each defendant when the summons is served on him,” not when the complaint is filed. Under § 15-2-20, if the debtor is out of the state when the claim accrues, the period runs from the person’s return, and time spent residing out of the state afterward does not count.
What restarts the clock in South Dakota
Section 15-2-29 is the only section on the subject:
No acknowledgment or promise is sufficient evidence of a new or continuing contract, whereby to take the case out of the operation of this chapter, unless the same be contained in some writing signed by the party to be charged thereby; but this section shall not alter the effect of any payment of principal or interest.
An acknowledgment or promise counts only in a writing you signed. The section says it “shall not alter the effect” of a payment but does not say what that effect is, and no other section of Chapter 15-2 does. That part is left to the courts.
How often South Dakota consumers report collection problems
South Dakota consumers filed 190 debt collection complaints with the Consumer Financial Protection Bureau in the 12 months ending October 7, 2026, which is 0.1% of the 316,737 filed nationwide and ranks 50th among reporting states.
Of those, 51, or 27% of the South Dakota total, were categorized as a collector taking or threatening to take negative or legal action, against 25% nationally.
These are raw complaint counts, not rates. They are not adjusted for population, and a complaint is an allegation the CFPB has published, not a finding that a company broke the law. The figures refresh weekly from the CFPB’s public database.
If you are sued on a debt you believe is too old
Under § 15-2-1, “[t]he objection that the action was not commenced within the time limited can only be taken by answer or other responsive pleading.” If you do not respond to a South Dakota collection suit, the defense is lost, and a South Dakota judgment carries twenty years under § 15-2-6.
Two South Dakota-specific things to check: when you were served, since that is when the action counts as commenced; and whether the creditor claims a signed writing in which you acknowledged the debt or promised to pay. Court deadlines are short, so this is a point at which speaking with a South Dakota attorney or a legal aid organization is worth the call.
How South Dakota compares
The same question gets a different answer a state line away. These are the closest comparisons to South Dakota:
- North Dakota: next door, six years, with the same signed-writing rule
- Nebraska: next door, five years written and four unwritten
- Minnesota: next door, six years on consumer debt, and nothing revives it

This page explains what the South Dakota statutes say. It is general information, not legal advice. It does not say what effect a payment has on the deadline, because § 15-2-29 preserves that effect without stating it.
