A:Every state enforces its own laws that limit the amount of time you have after your accident to file a lawsuit. This is referred to as the "statute of limitations." In South Dakota, people who have been injured as a result of someone else's negligence may file a personal injury lawsuit against the other party for up to 3 years after the date of your accident. If you wait too long to file a claim, your lawsuit will likely be dismissed by the South Dakota court system.
