Lawsuit Steps in South Dakota
Hire an Attorney
Most personal injury attorneys in South Dakota work on contingency — no upfront fees. They evaluate your case and advise on whether litigation makes sense.
Investigation & Evidence
Your attorney gathers medical records, accident reports, witness statements, and expert opinions to build the strongest possible case.
Demand & Negotiation
Before filing suit, your attorney typically sends a demand letter and attempts settlement. Most cases resolve without going to court.
File the Complaint
If negotiations fail, your attorney files a complaint in the appropriate South Dakota court. You must file within 3 years of the injury.
Discovery
Both sides exchange evidence, take depositions, and may hire expert witnesses. Discovery typically takes 6–18 months.
Mediation / Trial
Most cases settle during or after discovery. If not, your case goes to trial before a judge or jury under South Dakota court rules.
Key South Dakota Law Facts
South Dakota uses modified comparative negligence under SDCL § 20-9-2 with a 51% bar — plaintiffs who are 51% or more at fault cannot recover any damages; below that threshold, the damages award is reduced proportionally by the plaintiff's assigned percentage of fault.
Personal injury claims must be filed within 3 years from the date of injury under SDCL § 15-2-14; the statute may be tolled for minors, incompetent persons, and under the discovery rule for injuries or wrongdoing that were not immediately apparent.
South Dakota does not require no-fault personal injury protection insurance and operates as a traditional at-fault tort state, requiring injured parties to prove negligence or another theory of liability to recover compensation from the responsible party.
