I am a business owner in Sioux Falls and believe I may have been the victim of fraud that took place four years ago. In South Dakota, when does the statute of limitations for a cause of action for fraud start?

Under South Dakota law, in an action for relief on the ground of fraud, the cause of action shall not be deemed to have accrued until the aggrieved party discovers, or has actual or constructive notice of, the facts constituting the fraud.
