South Dakota Statute of Limitations: Civil, Criminal, and Tolling

The South Dakota statute of limitations sets how long you have to file a lawsuit or how long prosecutors have to bring criminal charges, and the answer depends entirely on what kind of case it is. Personal injury claims run three years. Medical malpractice runs two. Contract and property damage claims run six. Most crimes must be charged within seven years, but the most serious felonies have no deadline at all. Miss the window and the case is over, no matter how strong the underlying facts.

Personal Injury and Wrongful Death

You have three years from the date of injury to file a personal injury lawsuit in South Dakota.¹ That covers negligence claims from car accidents, slip-and-fall incidents, and similar situations. The clock starts on the date of injury, not when you hire a lawyer or decide to sue.

South Dakota courts have recognized a limited discovery rule for injuries that are not obvious right away, meaning the clock may start when you knew or reasonably should have known about the injury. The exception is narrow and courts apply it cautiously.

Wrongful death claims also carry a three-year deadline, running from the date of death rather than the date of the underlying injury.² That distinction matters when someone is injured and survives for a period before dying.

Medical Malpractice

Medical malpractice has a shorter and harsher deadline: two years from the date the malpractice occurred.³ The statute uses “occurred,” not “discovered,” so the two-year clock runs from the date of the medical error even if you did not realize anything went wrong until later. A surgical complication that takes 18 months to manifest could leave you just six months to investigate, find a lawyer, and file.

The statute covers physicians, surgeons, dentists, hospitals, nurses, chiropractors, and other healthcare providers, whether the claim rests on negligence or contract.

Product Liability

Defective product claims for personal injury, death, or property damage carry a three-year deadline, but the statute explicitly includes discovery language: the three years begins when the injury occurred or when it “became known or should have become known” to the injured party, whichever is later.⁴ That built-in discovery rule is more generous than the general personal injury statute.

Contracts and Debts

Breach of contract lawsuits must be filed within six years, and it does not matter whether the agreement was written or oral. The statute covers any “contract, obligation, or liability, express or implied.”⁵

Contracts for the sale of goods governed by the Uniform Commercial Code follow a separate four-year deadline.⁶ The parties can shorten this to as little as one year in the original contract, but they cannot extend it beyond four. Promissory notes payable at a definite time are generally subject to a six-year deadline after the due date.⁷

For general consumer debt like credit card balances, the six-year contract limitation typically applies, running from the last payment or default. That does not erase the debt, but it eliminates the legal mechanism to force collection through the courts.

Property Damage and Land Claims

Property damage claims from trespass, construction defects, or negligence must be filed within six years, whether the damage is to real property or personal property.⁵

Adverse possession claims require continuous occupation of the property for at least 20 years before the true owner loses the right to reclaim it.⁸ Prescriptive easement claims also require at least 20 years of continuous, open, and hostile use.

Assault, Defamation, and Wage Claims

Certain civil claims face a two-year deadline: assault, battery, false imprisonment, libel, and slander.⁹ Wage claims fall under the same two-year statute, with the clock running from the date the wages should have been paid. Federal unpaid wage claims under the Fair Labor Standards Act also carry a two-year deadline, extended to three years if the employer’s violation was willful.¹⁰

Federal Civil Rights Claims

South Dakota has a specific statute setting the deadline for federal civil rights lawsuits under 42 U.S.C. § 1983, which covers claims against government officials who violate constitutional rights. The deadline is three years from the date of the alleged violation.¹¹ Most states force federal courts to borrow the general personal injury deadline; South Dakota’s explicit three-year period eliminates the ambiguity.

Suing a Government Agency: The 180-Day Trap

Suing a state or local government agency requires an extra step that catches many people off guard. You must file a written notice of claim within 180 days of the injury, describing the time, place, and cause.¹² This deadline is separate from and independent of the underlying statute of limitations. You could have two years left on a medical malpractice claim against a public hospital, but if you did not file notice within 180 days, the case is over before it starts.

Criminal Prosecution Deadlines

South Dakota puts time limits on how long prosecutors have to bring criminal charges, with one large exception: the most serious felonies have no deadline at all.

Felonies With No Time Limit

Class A, B, and C felonies can be prosecuted at any time, no matter how many years have passed.¹³ The category includes first- and second-degree murder, all three degrees of rape, first- and second-degree manslaughter, first-degree kidnapping, first-degree robbery, first-degree arson, first-degree burglary, and terrorism. A murder or rape suspect does not become safe from prosecution because time has passed.

Everything Else: Seven Years

Every other criminal prosecution, including lower-level felonies and misdemeanors, must be commenced within seven years.¹⁴ South Dakota does not have a separate, shorter deadline for misdemeanors, which is unusual. A low-level theft misdemeanor and a Class 1 felony assault carry the same seven-year window.

Forgery and theft use a discovery rule: the seven-year clock starts when the crime is discovered rather than when it was committed.¹⁵ If prosecution comes more than seven years after the act itself, the state must prove the crime could not reasonably have been discovered earlier.

If a suspect leaves South Dakota after committing a crime, the limitations clock stops running for as long as they remain outside the state.¹⁶ Time spent out of state does not count toward the deadline.

When the Civil Clock Pauses

Several circumstances pause the statute of limitations on civil claims. These pauses are called tolling and they apply automatically when the conditions are met.

Minority and Mental Illness

If you were under 18 or mentally ill when the claim arose, the limitations period does not start running until the disability ends.¹⁷ A child injured at age 10 in a car accident would have until age 21 to file a personal injury lawsuit, which is three years after turning 18.

Mental illness tolling is capped. The disability cannot extend the filing deadline by more than five years, and in no case more than one year after the disability ends. Only infancy carries no cap on extension.

Fraudulent Concealment

When a defendant deliberately hides wrongdoing, the statute of limitations may not begin until the fraud is uncovered. South Dakota’s general six-year statute explicitly covers fraud claims, and the discovery principle prevents a bad actor from running out the clock through deception.⁵ The plaintiff carries the burden of showing that concealment actually prevented earlier discovery.

Military Service

Under the federal Servicemembers Civil Relief Act, any period of active military service is excluded from the computation of statutes of limitations in state and federal courts.¹⁸ The protection applies to servicemembers as plaintiffs or defendants. A South Dakota resident deployed overseas for two years effectively adds those two years to whatever filing deadline would otherwise apply. IRS collection matters are excepted.

What Happens If You Miss the Deadline

Once a civil statute of limitations expires, the defendant can ask the court to dismiss, and the court will grant it. The strength of the underlying case does not matter. Clear liability, documented damages, a sympathetic story: none of it saves a time-barred claim. Courts have essentially no discretion.

The effects reach beyond litigation. Insurance companies and opposing parties track these dates carefully. Once the statute expires, any leverage in settlement negotiations evaporates because the other side knows the lawsuit threat is empty. A breached contract becomes unenforceable. The breaching party walks away.

In criminal cases, expired deadlines can result in dismissal of charges. If prosecution was not commenced within the statutory window, defense counsel will raise the issue and the case is over regardless of the evidence.
